I have an internal DNS as part of my AD setup. I have an hosted DNS for public resources (which are typically at some data centre somewhere)
Occasionally while on our internal network I need to get to a public resource --- for example since there isn't a www record in our internal DNS I cant get the name resolved.
How do I configure my DNS to forward names it doesn't recognise to the public DNS.
Update:
As per the comment yes I have a "split-horizon" dns (which seemed like a good idea at the time)
This AD setup is less than 24 hours old, and can be redone if need be -- (although I would rather not)
It sounds like you have split-horizons DNS, where your AD namespace and public-facing namespace are the same. If this is the case, you'll need to make an A record for www in your internal AD zone and set the correct external IP. Without this, internal clients won't be able to resolve it. This is because you have two sets of servers with disjoint information that are both authoritative for your DNS zone.
www
This is the exact reason that Microsoft recommends using an unused third-level domain name for your AD namespace. For example, if you own mycompany.com and you host public websites on it, you should use something like corp.mycompany.com or internal.mycompany.com for your Active Directory namespace. If you can do a domain rename (i.e. you have a simple client/server infrastructure with no Exchange in the domain), you should look into it. If you can't do a domain rename to fix this, you're in for some headaches.
mycompany.com
corp.mycompany.com
internal.mycompany.com
Edit: Per your update, you should absolutely redo this since the install is only 24 hours old. Absolutely no doubt about it. Having a split-horizon DNS situation is never a good idea when it can be avoided. You can still have mycompany.com be the NetBIOS name of the domain, so users see MyComapny\User instead of something like Corp\User, but the FQDN of your AD namespace and the FQDN of your public facing DNS namespace should not be the same.
MyComapny\User
Corp\User
Go into your DNS Management Snapin. Right click on the DNS server you are managing. Select the "Forwarders" Tab and enter the DNS servers you want to forward requests to.
Your internal zone matches your external zone, right? So company.com is your internal AD zone and your external public zone? If that's the case then it can't be done with Windows Server DNS, that I'm aware of.
The Windows DNS server is authoritative for the zone as far as it's concerned so it's not going to forward requests for the zone to another DNS server, even if the request is for a DNS record that doesn't exist.
It should in principle be fairly simple to create a PowerShell, VBScript or other tool that periodically queries an external DNS server, reads the external DNS IP addresses for given hosts, and updates them accordingly on the internal Windows server.
I have looked several times but have yet to find one, and am disinclined to write it myself.

I am using Jupyter notebook to manage 3D slicer.
I am trying to control 3D slicer using python commands to automate the use of one Module.
I want to edit the buttons of the module so that I can insert the data from Jupyter. For example, when it says insert Input volume, instead of using the 3D slicer GUI, use python commands.
Can anyone help me with this, thank you!!
I am using Jupyter notebook to manage 3D slicer.
I would recommend to start with the Scripting and module development tutorial and then check out the Python FAQ for information on how to use CLI and Loadable modules from Python scripting. You can also find many examples in the script repository and in the modules section of the developer manual and in Python-scripted module tests. Since all these documentations are indexed by search engines, you can also google any question that you have. If you don’t find answers to any specific question (e.g., how to access a certain feature of certain module from a Python script) then you can ask it here.
Thank you for your answer Andras, I am going to check all the provided information
Hi. I couldnt find the solution to my problem.
I am going to explain it better. I am using the a module and I want to automate the process.
For example, in this box I need to choose “Create new volume”. Do you know if there is any python code I can write instead of having to click it with the mouse.
If the YourExtension you want to automate has a YourExtensionLogic(ScriptedLoadableModuleLogic) class then you would need to find the settable parameters in that class.
Example: This code sets some necessary things in the LungCTAnalyzer extension logic from a Python script.
import LungCTAnalyzer from LungCTAnalyzer import LungCTAnalyzerTest from LungCTAnalyzer import LungCTAnalyzerLogic logic = LungCTAnalyzerLogic() # loadedVolumeNode and loadedMaskNode were created before logic.inputVolume = loadedVolumeNode logic.inputSegmentation = loadedMaskNode logic.rightLungMaskSegmentID = loadedMaskNode.GetSegmentation().GetSegmentIdBySegmentName("right lung") logic.leftLungMaskSegmentID = loadedMaskNode.GetSegmentation().GetSegmentIdBySegmentName("left lung") logic.setDefaultThresholds(-1050,-990,-650,-400,0,3000) logic.detailedSubsegments = True logic.shrinkMasks = False logic.countBullae = False
When ready, you would
logic.process()
to do the actual work.
Thank you for your answer.
I am trying to use SlicerIGT (SegmentationUnet module) but there is no SlicerIGTLogic class, do you know any other way to achieve this?

mlockall()
Lock all of a process's address space
Synopsis:
#include <sys/mman.h> int mlockall(int flags);
Since:
BlackBerry 10.0.0
Arguments:
- flags
- Flags that indicate which pages to lock; one or more of the following bits:
- MCL_CURRENT
- Lock the pages currently mapped into the address space of the process.
- MCL_FUTURE
- Lock the pages that become mapped into the address space of the process in the future, when the mappings are established.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The mlockall() function causes all of the pages mapped by the address space of a process to be locked and made memory-resident until unlocked, or the process exits or executes another process. The pages that are locked depend on the flags argument.
Memory-resident is a term used to indicate that the addresses always reside in physical memory. For more information, see " Locking memory " in the Process Manager chapter of the System Architecture guide.
In order to lock pages, your process must have the PROCMGR_AID_MEM_LOCK ability enabled. For more information, see procmgr_ability().
Follow either of the following approaches when attempting to lock pages:
- Tightly controlled approach
- Lock the pages one by one, by calling mmap() and then mlock().
- Global approach
- Lock all pages at the same time, by doing one of the following:
- Call mlockall(MCL_FUTURE), followed by one or more calls to mmap().
- Optionally call mmap(), and then call mlockall(MCL_CURRENT).
Errors:
- EAGAIN
- Some or all of the memory identified by the operation couldn't be locked when the call was made.
- EINVAL
- The flags argument is zero.
- ENOMEM
- Locking all of the pages currently mapped into the address space of the process would exceed an implementation-defined limit on the amount of memory that the process may lock. lock. This implementation-defined limit is set by RLIMIT_MEMLOCK rlimit.
- EPERM
- The calling process doesn't have the required permission; see procmgr_ability().

Our ListeningThread class will need to inherit from threading.Thread and contain a run method, which can happen in the background.
Since we want to be always checking for new messages until the user closes their ChatWindow, we shall put our request inside a loop which the ChatWindow will be able to end when closed.
Let's begin our ListeningThread class, as follows:
import arrowimport threadingimport timefrom requester import Requester
Our class will be making use of the following modules:
- arrow: This is used to create the timestamps
- threading: This is used to run in the background
- time: This is used to sleep for two seconds between requests
- requester: This is used to contact our web service

4: The cost
In July 2014, JS Bin finally landed Pro accounts. The aim of this would be for JS Bin to eventually be self-sustaining. It's been running out of my pocket for the previous 6 years (for server and related costs), and development and design (2014 excluded) had been lovingly "donated" by myself and Danny (who is responsible for the design).
In 2014, I decided to give JS Bin a full shot, and employed two (amazing) developers, Giulia Alfonsi and Fabien O'Carroll to work with me full time on JS Bin.
At the end of May 2015 (10 months after launching pro) the income JS Bin has provided has only just covered operating costs for the previous year. That's awesome and terrible at the same time. Before "pro" it was making a 100% loss - so that's something, but it doesn't even touch the edges of what I had hoped it would return (and I wasn't even being optimistic, as any British person would expect).
But there is a cost to taking money...
VATMOSS
VATMOSS was a change to the way that VAT is processed in the EU. Unfortunately, the geniuses behind the change at the EU (or whatever rock they hide under) hadn't quite thought the whole thing through. The information was thin, convoluted, confusing and not really accessible to small companies like myself and many others.
This is the landing page for the EU European Commission's Digital Market:
The European Commission is the EU's executive body. It represents the interests of the European Union as a whole (not the interests of individual countries).
The slogan: bringing down barriers to unlock online opportunities. What a crock of shit. VATMOSS has single handedly killed off new business and for others made it more difficult for others do to their commerce. It's worth reading around the back story of VATMOSS, and even in mid-2015, it's there's a fight for change going on.
The VATMOSS reporting is now (as of 1-Jan 2015) a requirement for anyone in the EU selling digital services or goods (i.e. ebooks, apps, subscriptions...JS Bin Pro subscriptions), and there was (and is) the threat of fines if you don't report and pay on the sales correctly.
VATMOSS requires that you charge the VAT of the country of your customer. i.e. if the customer is English, 20%, if they are Danish 25%. Also, you have to capture three proofs that you're charging the right country (it's actually 2 proofs, but you need a 3rd backup proof). If these are all in conflict... ¯\(ツ)/¯
The last month of 2014 were riddled with stress from the VATMOSS changes that I had to complete on JS Bin. It took weeks to try to fully understand VATMOSS, and what exactly would be required to satisfy requirements.
In the end, the development time was about 2 week for both myself & Fabien (employed to work on JS Bin) and about two weeks of research, filing and accounting time on Julie's part (my business partner - and wife).
Estimated business cost: £3,500.
£11.70p. VATMOSS, the stress of it all, to collect pennies from seven people. It would have been cheaper to book flights to each of their addresses to collect the cash by hand. It was not fun.
Fraud credit cards
Since pro accounts initially cost £6 for month, it turns out that this is low enough that it won't send red flags to stolen cards.
This means that JS Bin was being used as a testing ground for stolen card numbers. If the card went through then they would use the card. Unbeknownst to me, the user wouldn't do anything on JS Bin, and I'd be on my merry way thinking I had a new pro sign up.
Eventually, the rightful owner would think, "What's this 'JS BIN PRO MONTHLY' doing on my statement", follow up with their bank, and raise a fraud complaint.
I can't win the complaint. The card was stolen, the £6 belongs to the original card owner, no question. But! If there's a dispute on Stripe, there's transaction fees for reversing charges. £15.34 in fact. Since I know I'll lose the dispute, it's cost me, £21.54 to allow some shithead to use JS Bin as a stolen card testing facility.
My process now is that I've taken to checking each and every individual sign up and their bins to see if they look spammy. I caught my first fraud card and reported on 13-April 2014. Not a huge success but very satisfying to know I've avoided the charge. Woot!
Pro
Pro accounts was never the intention when I launched JS Bin back in 2008. I'd made stupid efforts to avoid having user accounts for quite a few years, but insisted that it should be 100% free.
I don't know why.
During 2013, I attended a lot of events where individuals kept coming up to me asking how do they pay for JS Bin, or why don't I add Pro, or explained that the only reason they used CodePen over JS Bin was that they were paying (i.e. the perceived security of data from the business exchange). The more I considered it, the more I realised I wanted to do JS Bin full time, and work on something I loved.
I ran some numbers based on registered users in the database, and factored for about 20% spam/idle users, and then put my aims at 1% conversion. It didn't seem like much.
The problem was: that's all I did.
There was no business plan. There was no business development team. There was no marketing plan. There was no deadlines. There were no aims.
So there my amazing product sat. To others it was ready to launch, but I was still heads down focused on the last 1% stretch, so it was parked.
I'd had the odd conversation that suggested I might be able to get funding from the government (as JS Bin is a tool primarily for learning), but I'd shy away from the idea of having to do "business" stuff. It scared me a little too.
Launching became the well know problem of chasing the end of the rainbow. Striving for the perfect, polished product before everyone else had access to it. Sure we had some alpha users in there, but they weren't invested in JS Bin any more than you are, so feedback came when they had some time.
This went on for months and months. All the while JS Bin isn't making money, my entire company is focusing it's time on JS Bin and not producing any cash flow from any other sources.
Pro (eventually) went live on 23 July 2014. And the first wave of registrations was an amazing feeling. In fact, one user (David Gauld, who actually worked for me doing the Left Logic redesign and built a fair amount of confwall) was the first to go pro catching the commit landing in Github, even before I had announced it - a cool side effect of the open source.
Users did come, but looking back, it really wasn't very much if you consider the costs of running JS Bin, let alone paying for development, and then look at what the monthly (or yearly subscriptions) got us. A total of 42 upgrades in the first week (26 were on the first day).
I had always tucked money aside for a rain day (actually rainy year), and yeah, I can look back and say "sure, I took a shot" - but it came at a pretty penny.
The next 6 months I lost my love for the project. Very simply: any new development had to justify its existence and its demand on my time. I did continue development until the end of 2014, but by that point, all love had been sucked dry and I needed a break. JS Bin is solid enough that it can run without day to day attention and I could return to client work and try to recover my now sad looking business bank balance.
Plan, and know what your users need
There were two major problems that hurt the success of JS Bin Pro.
The first was the nearly zero planning, and strange fear of business, marketing and actually making money. I often associate with the underdog, and those users looking for free access. But I run a service that's abused from all directions and every new user is more of a burden than growth.
Very simply put: should I want to run a service for 100 paying users or for 100,000 non-paying users? Me? Now, I realise it's the 100 paying users, because, honestly, I've got bills that I want to pay. I'd rather pay those bills building something I love rather than building something I begrudge.
I lost a lot of love in this area of working with JS Bin. I can take the spam, and the junk, but this part of JS Bin required that the project actually raises money to support itself - and constantly feeling that I had to deliver some part of code for JS Bin to continue...it just didn't work for me.
The second, major issue was that I had hoped, naively, that the web community will swoop in and pony up some cash. But the bottom line was JS Bin Pro had nothing that users needed. Sure, now it has asset uploads and other features, but at the time, there wasn't anything users really needed.
I pay for my Github account because I need private repos. I pay for Gmail, because I need real business email accounts. I pay for Dropbox because I need the extra space.
With JS Bin, everything users need is given away and open source. That's honourable, but doesn't pay the mortgage.
The next time around, with products like Confwall, I launched as soon as it was usable. I offer a free area, but I make sure that you can't get to the stuff you need unless you pay. The way it should be! In fact, at time of writing this post, Confwall still doesn't take payment online - I cut that part to launch as early as possible, and we handle payments via email & invoices.
Part 5 sees our conclusion and tells of the police encounters I've had, along with the worst email I've ever received. | https://remysharp.com/2015/09/17/jsbin-toxic-part-4 | CC-MAIN-2018-51 | refinedweb | 1,786 | 79.6 |

You are going to have to provide your code, what the name of that code file
is and what URL you were using is.

You can always set up mod_python.publisher as:
AddHandler python-program .html
PythonHandler mod_python.publisher
Do this though and you can't have static .html files in the same
directory as mod_python.publisher expects to be handling all
.html requests.
It also doesn't work well if you expect to have multiple published
methods in the same file, whether in a flat namespace or hierarchical
by using objects. This is because the URL for the published methods
ends up actually being something like:
Ie., the ".html" extension isn't at the end of the URL.
The only other option you have is to get messy and use mod_rewrite
to remap actual ".html" URLs to mod_python.publisher style URLs on
the fly.
Other than that, you would have to look at using an alternate
extension package for mod_python that focuses more on resource
based URLs where the URL reflects the type of content being returned.
When using mod_python.publisher you almost have to use REST
style URLs, ie., no extension to stop the ".py" appearing.
Maybe you would like to explain what you are trying to achieve and
whether you are using some templating system or using handcrafted
HTML. People may then be able to suggest better alternatives.

Professor Emeritus UCLA Anderson Graduate School of Management
One problem that has been highlighted in discussions of California’s budgetary problems is the volatility of its tax sources, particularly the income tax. Jerry Nickelsburg suggests a possible solution to tax volatility. Although Proposition 13 of 1978 is often seen as a cause of California’s proneness to fiscal distress, Nickelsburg suggests it could be the key to reducing tax volatility. Because Prop 13’s assessment mechanism means that most property is valued below market, it has become a comparatively stable revenue source for local government. A modest increase in Prop 13’s tax rate, combined with its current under-market assessment mechanism, could lead to greater state revenue stability, if the incremental revenue could be diverted to the state in a revenue-neutral fashion.

A little more than a year ago, with a fair amount of hoopla, California became the first state in the nation to pass a bill aimed at decreasing driving as a means to reduce greenhouse gas (GHG) emissions. Such emissions are those responsible for global warming and other forms of climate change. The state did so by taking on the complex nexus of land use, transportation, and housing. Simply put, the legislature set a course aimed at changing neighborhoods, highways, transit options, and other land-use patterns to reduce our miles on the road. The goal was ambitious, especially for the purported home of the drive-through restaurant. 2 And it is too early to determine whether the law, known as SB 375, 3 will significantly and cost-effectively reduce greenhouse gas emissions from the transportation sector. But it has certainly garnered media attention. The law won praise from the New York Times editorial board (which called it “[t]he latest example of California’s originality” and urged other states to follow suit).4 At the other end of the spectrum, the Orange County Register called it “one of the most authoritarian, far-reaching and elitist bills that has ever made it to the Governor ’s desk”.5 Other media reaction ranged between these two points of view. For land use planners, SB 375 has served as a Rorschach test. At the time of its enactment, some observers considered it the most important change in planning law since the California Environmental Quality Act (CEQA). Others saw it as providing “incremental change, not land use revolution.” Opinions about its worth often reflected both varied beliefs in the utility of centralized land use planning and one’s stake in the bill’s creation and passage. 6 The first few steps of SB 375 implementation have now been taken. Much has been written about the law, but this chapter provides relatively brief answers to three questions: What gave rise to the law? What does it say? And what has the first year of implementation revealed about its significance and its likelihood of success?

Whether SB 375 will lead to real achievement will depend on at least three things. First, there is the issue of whether the law’s incentive structure will work to spur compact housing development. It might turn out that CEQA exemptions are not nearly enough to entice builders into compact infill projects. A host of other structural and political barriers may make those projects very difficult despite the exemptions. 5 5 Second, it is unclear if the bill’s varied incentives will work well together. Sustainable Community Strategies are holistic plans, with parts dependent on each other for success (increased housing built near improved transit lines, for example). Incentives, however, operate project by project. What if the bill succeeds in spurring high-density development along transit corridors proposed for expansion, but the dollars to make that transit expansion a reality never come? Third, and last, it remains to be seen how influenced people are by being shown what is possible. Part of the impetus for the bill might best be described as hope: if we envision it, they will come. Whether that hope is justified will not be apparent for many years.

CARBON COSTS AND HOUSEHOLD ELECTRICITY EXPENDITURES IN CALIFORNIA
MICHAEL J. SANDLER Michael Sandler is co-founder of the Climate Protection Campaign based in Sonoma County, California. He has helped develop climate change programs for cities, water agencies, air quality districts, and the faith community. He received his MA in Urban Planning from UCLA, where he conducted research on carbon markets at the Lewis Center for Regional Policy Studies.

Once people are satisfied that climate change is real and something should be done about it, they want to know, “What do we have to do, and how much is it going to cost?” This chapter begins to answer the second part of that question. It examines a $15/ton cost on carbon dioxide (CO2) to household electricity bills in California, based on research conducted
with support from the Lewis Center for Regional Policy Studies at UCLA. Although carbon pricing is an important economic lever in the economywide transition away from fossil fuels, the chapter concludes with a brief discussion of policies for returning revenues to consumers as a dividend, tax rebate, or share in order to assist households with the short-term costs of capping carbon.
M O V I N G A W AY F R O M FOSSIL FUELS
Climate change policies that shift economic production and consumption away from fossil fuels over the next few decades may produce a net economic gain over time. They could do so by increasing energy efficiency, by creating new jobs in industries such as renewable energy, and by avoiding the enormous costs of catastrophic climate instability. However, climate change legislation is also expected to add shortterm costs to the utilization of fossil fuels including coal and natural gas used to generate electricity and transportation fuels. This chapter estimates the increase to the average California household’s annual electricity bill if a $15 per ton CO 2 cost had been applied retroactively to
coal and natural gas prices in 2005. The results are based on projections of a carbon cost’s effect on coal and natural gas prices from a model developed at MIT. Also projected is the contribution to California’s carbon costs resulting from the carbon-intensive, coalfired electricity that is generated in the neighboring states of Oregon, Nevada, Utah, Arizona, and New

California’s electricity prices, as a partially deregulated market, are theoretically determined by the marginal costs (defined as the operations and maintenance (O&M) costs of the most expensive generating plant needed to supply the immediate demand for electricity). However, the estimate here assumes average cost pricing is used as under traditional regulated state electricity systems. (Average costs are determined by the cost-of-service of the regulated entity, i.e. total costs divided by total sales.) The resulting carbon costs are meant to represent

expenditures for fuel in the transportation sector. Transportation fuel consumption is based on U.S. Department of Transportation data on gasoline consumption for private vehicles by state for 2005. Because gasoline has a lower carbon content than coal (see Figure 2), the MIT EPPA model adds only 14.3 cents per gallon to 2005 motor fuel prices compared to over $30 per short ton of coal. When the same $15/ton CO 2 cost is added to 2005
household transportation fuel consumption in the 50 states, the average household’s transportation fuel expenditure increases $76, from $1,811 to $1,887. For California, when the gasoline price goes from $3.78 to $3.93, the average household pays an additional

$84.75. Adding the carbon costs from electricity to those of transportation, the average California household would pay $122.41. This still leaves out indirect costs paid by households for other goods and services due to increased electricity prices.

Cathy Kunkle and Dan Kammen from UC Berkeley projected that a policy that returns 50% of allowance value to households through dividends would benefit households in the poorest deciles more than the wealthiest deciles. They also find that California’s northeast counties generally have higher carbon costs than the coastal counties.8

mix, household consumption, electricity prices, and the MIT-EPPA model’s projection of a carbon cost’s effect on coal and natural gas prices. Although a carbon cost will shift demand away from fossil fuels and toward renewable energy, moderating household carbon costs can address disproportionate costs to low-income households and encourage longterm political support for economy-wide emission reductions. The most direct method to moderate consumer impacts is to return a portion of carbon costs back to consumers through a cash dividend, tax rebate, or transferable emissions share. The return of allowance value could represent a transfer of billions of dollars. Depending on the distribution method, the net cost to Californians could be entirely eliminated, albeit at the expense of other states. Policies to assist households with shortterm carbon costs are an important, part of state and national climate policy, and deserve further discussion.

California is in crisis.1 Amid what is often described as the worst economic situation since the Great Depression, 2 California is among the states hardest hit by home foreclosures. 3 The state suffers from the political inability to pass a budget and pay its bills, 4 has one of the highest unemployment rates in the nation, and has imposed mandatory furloughs on state employees.5 Highway and water system infrastructure throughout the state is crumbling, 6 and the state has declared a state of emergency for drought. 7 All of these daunting challenges must be addressed while California continues working to avoid the potentially severe impacts of climate change.8 Times of crisis can also be times of significant opportunity. The confluence of numerous challenges and demographic changes has created an opportunity for meaningful and long-lasting reform in land use and transit infrastructure in California. Through integrated policies, California can build a more sustainable society while putting people to work, improving public health, and reducing greenhouse gas emissions. As the economy begins to recover, the question becomes how will California move forward. Will the state fall back upon failed systems, or choose a stronger future? This chapter addresses the necessity of reform and innovation in the land use and transit arena. In Section I, the various challenges mandating the need for change are reviewed. Section II then surveys the synergistic benefits attainable through increased use of public transportation. Section III examines three elements of reform for public transit funding and transit-oriented development. First, Section III considers the potential impact of Senate Bill 375, a landmark bill addressing land use and transit planning in California. 9 Second, the section looks at public support for mass transit, particularly the success of local transit sales tax measures on the November 2008 ballot. Third, Section III reviews potential funding mechanisms and price signals to encourage transit use.

HARNESSING THE MARKET TO DISCOURAGE SPRAWL IN CALIFORNIA
PHILIP J. ROMERO
1
Philip J. Romero is Dean of the College of Business and Economics at California State University Los Angeles, and a principal in the Forward Observer and Third Century Solutions public policy consulting firms. As chief economist to the governor of California in the 1990s, Romero designed market-harnessing changes in public policy that contributed to the state’s turnaround in the mid 1990s, from last to first in the nation in economic performance. The author or co-author of six books on policy and economic topics, he earned his PhD from the RAND Graduate School. His latest book is A Boomer ’s Guide to Preserving Your Wealth from Washington, forthcoming in 2010.

Urban planners have long attempted to mandate reductions in “sprawl”, but they often run afoul of both consumer preferences for detached homes and existing land use policies (exclusionary zoning). A better approach would be to work with the market, not against it. A period of deep recession presents an ideal opportunity to put in place new policies to avoid repeating past mistakes. Most of the overbuilding in California in the first half of the decade occurred on the urban fringe. Thousands of excess homes led to one of the nation’s highest foreclosure rates, which aggravated an already steep economic downturn. This overbuilding wasted not only economic resources, but also natural resources. Policy innovations which can encourage denser infill development can help make the next boom more economically and environmentally responsible. “Smart districts,” modeled after redevelopment areas (RDAs), would allow some fraction of tax revenues generated inside the district to be retained for reinvestment in infrastructure or amenities for districts that commit to higher density development. The critical assumption is that richer amenities and infrastructure will attract private investment, and thereby encourage faster economic growth. This chapter estimates the economic impact of such districts if implemented statewide. Based on the historical experience of California’s redevelopment areas, it is reasonable to assume that the average smart district will, conservatively, accelerate economic growth within its boundaries by 4.6% to 8.3% per year. If implemented on a moderate to large scale, this additional growth will translate to an increase of 1,300 to 12,300 jobs per year; $95 to $885 million in personal income per year; and $124 million to $1.1 billion in added gross state product per year. Critics may argue that this faster growth comes at the expense of smart districts’ parent (surrounding) jurisdictions, because those parents “subsidize” the

districts by allowing them to keep a portion of locally-

In early February 2007, newly-elected California State Assemblyman Mike Feuer was approached by gun violence prevention activists Amanda and Nick Wilcox. They asked if he would sponsor a bill which would require that semi-automatic handguns sold in California include a newly-tested “microstamping” technology, which could be used to trace shells to the guns that fired them. There was no such requirement anywhere in the country. The Wilcoxes had worked on a failed attempt at the same law the previous session. But Feuer, even though he had a strong reputation on gun control during his six years as a Los Angeles City Councilman, was reticent. First impressions are important for a freshman legislator. He had an ambitious agenda in a wide range of policy areas. Feuer didn’t want to get pigeonholed as a singleissue assemblyman. It was the kind of bill that would require many hours of his time to pass, distracting from the rest of his agenda. And, perhaps most important, he didn’t want to fight a highly visible, losing battle first time out.
AN INITIAL A LT E R N AT I V E SPONSOR
The Wilcoxes had not originally planned on asking a freshman legislator to carry the bill. Their first hope had been Senator Darrell Steinberg. At the time, Steinberg was a freshman senator. But he had completed three accomplished terms in the Assembly and was preparing for a potential leadership role in the Senate. Steinberg had worked closely with the Wilcoxes on a range of issues helped with the successful passage of Proposition 63, a mental health initiative.

Initially, there was an assurance to the Wilcoxes that Steinberg was “99 percent sure” he would carry the

bill. However, they got a call from the Senator ’s chief of staff that he would not, just weeks before the deadline for submitting new legislation. The Wilcoxes turned to Kay Holmen, the Los Angelesbased president of the California Chapters of the Brady Campaign against Gun Violence. She, in turn, approached Feuer, and pitched microstamping and the Wilcoxes.
“The issues of mental health and gun violence came to us, we didn’t go to them,” the Wilcoxes say. After Laura’s death, Nick and Amanda, raised as Quakers and long-time contributors to the Brady Campaign, devoted themselves to improved mental health treatment and gun violence prevention. Just a month after the shooting, they organized a vigil at an annual
THE KILLING OF LAURA WILCOX Nick and Amanda Wilcox were not the kind to be easily deterred. Their 19-year-old daughter, Laura, valedictorian of her high school, had been shot and killed six years before. The shooting was a random incident, occurring as she worked as a fill-in during winter break at the Nevada County Mental Health Center. She was then a sophomore at Haverford
gun show at the Nevada County Fairgrounds, which Thorpe had been known to attend. A year later, the Wilcoxes pushed the California Department of Justice to send undercover agents to the gun show. The agents found banned weapons for sale, unlicensed dealers, and weapons sold without background checks or ten-day waiting periods as required by California law. Arrests were made, and the Wilcoxes were eventually successful in closing down the show.
College in Pennsylvania and had been an intern at the mental health center the previous summer. On the afternoon of January 10, 2001, Scott Alan Thorpe, 41, delusional, with a history of resistance to his family’s pleas to get mental health treatment, walked in to the Nevada Mental Health Center. There he shot and killed Laura Wilcox, who was working as a receptionist, Pearlie Mae Feldman, 68, a mental health caregiver, and severely injured Judith Edzards, 49. Thorpe then went to a local restaurant and shot two more people, killing one, Mike Markle, 24, the manager. After Thorpe was arrested, he explained to the police how the mental health center had angered him and how the restaurant had been trying to poison him. He believed he had settled the matter and asked the police when he could go home.
T H E C A M PA I G N
FOR “LAURA’S LAW” Over the next two years, the Wilcoxes were also instrumental and persistent in moving “Laura’s Law” through the California legislature and having it signed by Governor Gray Davis. The law allows involuntary outpatient treatment of mental illness patients if they are a threat to themselves or others. Laura’s Law was modeled after a similar New York state “Kendra’s Law.” Kendra was a young woman who was pushed in front of a subway train by a mentally-ill man. Laura’s Law proved difficult to implement without funding. In response, the Wilcoxes worked for the passage of Proposition 63, a state surtax on those with income above $1 million to support treatment for the

EXTERNAL WORK
While the Feuer bill was under consideration, the Brady campaign was reorganizing its California operation. Its one paid staff person was leaving. Brian Malte, the Washington DC-based director of state legislation
“liked big, high visibility initiatives” and, unlike most of the players in Sacramento, he viewed himself performing on a national stage. Additionally, for the national Brady campaign, California was to be just the first state in the country to require microstamping; there were 49 more.
for the Brady Campaign, stepped in to play a larger role in developing strategy for passage of the bill. Instead of immediately hiring a replacement, Malte advocated using the salary savings to hire a professional contract lobbying firm that would work on the microstamping bill. Malte and the Wilcoxes interviewed four such firms. They chose Political Solutions, a Sacramento organization noted for its political ties to

S E N AT E W O R K
The Wilcoxes and the Political Solutions staff continued to work on the Senate and cleared three hurdles with committee staff and Senate President Pro Tem, Don Perata. These hurdles involved 1) providing assurance that the bill would not contribute to prison overcrowding (a required provision of crime-related legislation), 2) adding language to defuse the sole-source concerns, and 3) convincing the senate president’s staff that AB 1471 was the Brady Campaign’s very top priority piece of gun legislation. In addition, they were also successful, along with Feuer, in persuading Perata to co-sponsor the bill. Meanwhile, the Wilcoxes concentrated on Senator Machado in particular. They spent time with one of Machado’s close friends in the Senate, Tom Torkalson (D-Antioch) and his staff, connecting back to the Brady Campaign’s strong chapter in Contra Costa, in Torlakson’s district. One Friday, they drove through Machado’s district and visited all of its police stations unannounced, speaking to a number of captains and dropping off literature. In time, they would have the endorsements of the Stockton, West Sacramento, Davis, Woodland, and Suisun City chiefs.
Feuer, whose name had now become synonymous with the microstamping bill, recalled his nervousness, no doubt with the UC-Davis study in mind, as he realized he had not yet seen a demonstration of it himself. “I remember driving to the Training Academy thinking, “This thing had better work, or my political career is going to go right down the drain. I’ll be a laughing stock.” With the media and the public officials looking on, an LAPD police officer fired bullets from guns outfitted with microstamping technology. Lizotte then examined the shells under a display microscope so everyone could see the identifying markings made by firing the gun. It worked; Feuer exhaled. “The Los Angeles County Sheriff’s Department Homicide Bureau has hundreds of unsolved cases where the only evidence left at the scene of the crime were expended bullet casings,” Sheriff Baca said in a press release. “If these casings had imprinted information on them from the firearm, our investigators would have an exceptional chance of solving these heinous crimes.” Another compelling speaker at this even was Tim Heyne, president of the Ventura County Brady chapter. Heyne’s wife and best friend had been shot, spent shell casings were scattered over his wife’s body, and there were no leads on the gunman until he killed
D E M O N S T R AT I N G THE TECHNOLOGY
Feuer had also developed an ally in Los Angeles Police Chief William Bratton, a powerful figure with a national constituency and a friend of the Governor. In August, through Bratton, Feuer arranged for the media demonstration of the microstamping technology with Todd Lizotte to be held at the Los Angeles Police department shooting range. Los Angeles Mayor Antonio Villaraigosa, Sheriff Baca, and LAPD Chief of Detectives Gary Brennan were all present.

T H E S E N AT E V O T E The California State Senate has 40 members; it takes 21 votes to pass a bill requiring a simple majority vote. (Budgets and bills with tax increases require 26 votes under a 2/3 rule). Around September 1, 2007, the Wilcoxes learned that Senator Florez would vote with them. He would be the 21st vote. The Bakersfield Californian editorial and the endorsement of Police Chief Dyer seemed to have played a role. They had to keep it a secret, however. If the opposition found

From 1979 to 2007, real wages of the inland agricultural areas of California suffered a marked economic deterioration relative to California’s large coastal metropolitan areas. 3 This chapter documents that relative decline and investigates possible explanations for wage divergence in California over the same period. It concentrates on twelve small inland Metropolitan Statistical Areas (MSAs) that, at first glance, would not seem to be candidates for economic distress. Eleven of these twelve areas compose one of the most productive swathes of farmland in the United States, if not the world. The San Joaquin Valley, which comprises eight of these metropolitan areas, exports more agricultural products than any U.S. state—other than California. And all 12 of these MSAs have been growing rapidly in population. Yet compared to the large coastal metropolitan regions of Los Angeles, San Diego, San Francisco and San Jose, real wages in these twelve MSAs are falling behind. Even as their populations have boomed, their wages have stagnated. In some cases, wages actually declined in real terms. At the end of the 1970s, these areas lagged behind the large coastal metros. From 1979 to 1999 the gap between these areas continued to widen. There was some recovery 1999 to 2007, but the gap is nonetheless still huge. It is not a surprise that wages in small metropolitan areas are less than wages in large ones. All twelve interior MSAs have populations well under one million. Larger places have greater congestion, longer journeys to work, and higher land prices. These factors raise the cost-of-living and exert upward pressure on wages (O’Sullivan 2007). But in the period after 1979, the percentage difference between average wages in the interior and the coast grew sharply. Figure 1 shows that from 1969 to 1979, real average wages for the twelve interior places in our study were low but moving in line with real average wages in

In part, this divergence is an artifact of the large differences in population between the coastal and interior regions. All four coastal MSAs have well over

And industrial specialization is itself tremendously difficult to disentangle from educational attainment. To a strong degree, industrial structure and labor force skill are jointly determined. The presence of skilled people can help incubate skilled industries.

ductivity enhances the average wage.
Third, it might be true that population size will interact with both industrial structure and educational attainment, and have a positive impact on the average wage. That is, there may be a wage benefit associated with a large MSA and a wage benefit associated with an educated populace. But there may also be additional independent effect that is generated by having educated people in a large place. Larger places, in other words, might obtain more from their educated people, in terms of productivity. Three reasons can be suggested why this phenomenon might occur.

Coastal MSAs range from a high of 35 percent (Los Angeles) to a low of 22 percent (San Diego). Interior MSAs range from a high of 32 percent (El Centro) to a low of four percent (Redding). Thus, Los Angeles has a greater share of foreign born than any of the 12 interior places, as does San Jose.

MEXICO AS A P O P U L AT I O N SOURCE The dramatic difference among the two groups of places is shown on the last column of Table 3, the percent of the foreign born from Mexico. The twelve interior MSAs have far higher shares of foreign-born from Mexico than the four coastal MSAs with a few exceptions. Only two of the interior places have shares below that of the coastal place, San Diego, with the highest share: 48 percent. Indeed, ten of the twelve interior MSAs have well over half of their foreign born from Mexico, ranging from 52 percent (Stockton) to 94 percent (El Centro). Almost all of the California places listed in Table 3 have shares in each category far above the national shares.

Certainly, MSAs such as Los Angeles and San Francisco have their share of economic distress, which a high regional average wage can mask. Future research should use individuallevel wage data to assess more closely the economic well-being of individuals within these regions.

BOOSTING E D U C AT I O N Another approach is to focus on education. Certainly higher education is a long-term answer for the young in California’s interior. However, anyone endorsing education as a solution for these areas should be aware that individuals in declining places will, once
118
educated, probably leave. Those who are educated will benefit. But the places from which they depart will not. Nevertheless, economic development in California should be first about helping people and only second about helping places.
T H E I M M I G R AT I O N CHALLENGE The people-place distinction is perhaps most acute in the case of immigration. It seems likely that the low levels of educational attainment in California’s interior reflect, at least in part, a steady influx of poorly-educated immigrants. So it is possible that immigration has had an indirect influence on wages in the interior. But a proper analysis of immigration requires consideration of its impact, not just on the places that receive the immigrants, but also on the immigrants themselves. In 1999, the per capita income in Mexico was about $4,500. In rural areas of Mexico it was much lower. Thus, almost every immigrant who came to the twelve interior MSAs in California was made better off as a result. But where immigration makes people better off, it can make places relatively worse off. The arrival of poor people increases the poverty rate, even if immigrants, once they arrive, are less poor than they once were. Anti-poverty benefits of immigration are international, but immigration’s costs—both economic and political—are often local. Resolving this tension will be a challenge for California in general, and for its interior in particular.

“Sometimes you will fail and be blamed for things you had absolutely nothing to do with.” —Former Governor Gray Davis Keynote speech to Columbia University Law School graduation, May 21, 20091
Gray Davis, the 37th governor of California, took office in 1999 in a period of prosperity. Unlike his two predecessors, Pete Wilson and George Deukmejian, both of which became governor in periods of budget crisis, Davis—thanks to what would eventually be known as the dot-com boom—was initially blessed with state revenue. By the time he ran for re-election in 2002, he was dealing with a major fiscal problem that eventually led to his recall a year later. His successor, Arnold Schwarzenegger, promised to fix the state’s budget problems and without a tax increase. Yet Schwarzenegger found himself mired in another budget crisis during his second term. Given that later history, in hindsight can Davis be blamed for the fiscal problems that led to his recall? Not surprisingly, there is not a clear-cut answer to that question. But it can be said that the style of Governor Davis’ leadership left him vulnerable to crisis. It can be said that despite the prosperous times in which he was initially elected, the state’s proneness to budget crises was apparent. And, it can be said that his successor was naïve about the difficulty of changing the institutional structure of the budget process.
DIFFERENT PERSONALITIES
“I have prepared my whole life for this moment.”
124
—Governor-Elect Gray Davis Shortly before taking office 2
Davis and Schwarzenegger were very different in background and personality. Davis, a Democrat, was a lawyer by training and was a career politician. 3 He served as chief of staff to Governor Jerry Brown and subsequently became a state assemblyman, controller, and then lieutenant governor. In the 1998 Democratic primary, Davis ran against two wealthy and selffinanced candidates, seemingly as the dark horse in the race. Yet his two rivals managed to defeat each other and Davis emerged as the winner in the primary. Davis based his campaign on his political experience and promised that his focus, if elected governor, would be on education. In the November general election, he easily defeated his Republican opponent, AttorneyGeneral Don Lungren. Arnold Schwarzenegger ran in the 2003 recall as an outsider—not a politician—who would clean up state politics. Although it was his movie career that made him a high-profile candidate, he emphasized his business background which would allow him to rid the state of governmental waste and inefficiencies. Because he was wealthy, Schwarzenegger argued, he would not have to depend on special interests. Schwarzenegger was most successful in terms of public approval when he displayed optimism and humor—and least successful when he seemed combative. In contrast, Davis retained the image of a somewhat stand-offish career politico. Despite these sharp differences in public personas, Governor Schwarzenegger ended up facing a budget crisis at least as severe as the one that defeated Davis in the recall. After a series of ballot propositions related to the budget were rejected by voters in a May 2009 special election, words such as “Armageddon” and images of California driving off a cliff were regularly used.
UP AND DOWN: A BUDGET SUMMARY OF THE DAVIS YEARS “Their job is to implement my vision. That is their job.” —Governor Gray Davis discussing the role of the legislature 4 Table 1 provides data on budget proposals made during Governor Davis’ period in office. Except for proposals made in 2003, the proposals are the initial ones made in early January for the coming fiscal year beginning the following July 1. For 2003, the table shows both the January and the “May revise” proposal; the May revise of 2003 was the last proposal made by Governor Davis because of the recall in October of that year. Proposals are not the same as the adopted budget ultimately passed by the legislature. But they do show the intentions of the governor. Yet they can be misleading. The table indicates that Governor Davis repeatedly— until the very end—submitted budgets that were expected to deplete the General Fund reserve. (We avoid the words deficit and surplus to describe these changes in the reserve because budget proposals are not confined on the receipt side to revenue but rather also include “transfers” from outside the general fund, including borrowing.) However, Governor Davis was not necessarily being profligate. During the dot-com boom, revenue kept rising faster than forecast, even relative to what was projected half way through the ongoing fiscal year. (Table 1 shows that projection as well as the proposal for the next fiscal year.) In the late 1990s, revenue from capital gains related to stock market and employee stock option capital gains poured into the state treasury. Although spending was being ramped up, in effect the legislature could not keep up with the inflow.

A ROLE FOR LEADERSHIP Some governors have pointed to underlying causes but not the whole picture. As noted, Jerry Brown’s “era of limits” suggested the rising cost of growth and a structural shift. But when it came to the major political consequence of the shift, Prop 13, Brown was either distracted or bemused and—in the end— flipflopped from opposition to the proposition before it passed to support afterwards. 8 7 Deukmejian took the taxpayer revolt as a given and the last gasp of the Cold War helped pull the California economy back on track. In any case, he had little incentive to look for an underlying shift that was being temporarily obscured.
and ultimately did navigate the state out of the budget crisis of the early 1990s. But his preferred remedy, in effect state control of immigration via Prop 187, was doomed to fail since immigration control is the province of the federal government. Subsequent litigation largely voided Prop 187. Finally, neither Gray Davis nor Arnold Schwarzenegger focused on underlying trends. Davis came into office during the dot-com boom when, despite the employment lag shown on Chart 3, the budget position of the state was temporarily strong. Ultimately, Davis viewed his fate as a function of the short-term business cycle. “Nobody seems to understand that the economy is like the tide,” he complained. “When you’re in high tide no one thinks low tide is coming.”8 8
Wilson looked at the demographic element as an underlying cause of California’s budgetary problems
155
Schwarzenegger tended to point to the political symptoms of the underlying shift. His suggested political reforms, such as a larger rainy-day fund, would help at the margin. But his communications skills were never pointed toward acquainting the public with the difficulties the underlying economic shift entailed and the implications for public policy. Probably, his natural tendency toward optimism made it difficult to contemplate the idea that California had become a normal state in terms of its growth potential. The Bad News is that California’s virtuous circle of growth leading to revenue to supply the infrastructure for more growth began coming to an end in the 1970s. The state’s size help obscure that reality. California politicians often point to the fact that if the state were a country, it would be the 6 th or 7th largest in the world. But apart from electoral votes, size doesn’t matter. The Good News is that being average is not a terrible fate—if only California could find a leader to make the challenges of the transition explicit. Perhaps voters now realize that expecting a man (or a woman) on a white horse to fix the state’s fiscal problem is unrealistic. The question is whether whoever emerges from the 2010 gubernatorial election will be willing to acquaint voters with the idea of California as a normal state.

Those who think California lacks seasons miss the well-defined season of discord in Sacramento’s halls of government. The drama of the fiscal budget season is made all the more complex and interesting by its reliance on revenue estimates; estimates which are at best a moving target. Revenue “shortfalls” for the combined 2008-09 and 2009-10 fiscal years were described at times as $12 billion, as $40 billion dollars and as $60 billion.1 This was a huge margin of error when one considers that the 2007 fiscal year general fund was $103 billion. Regardless of the forecast one uses the adjustments in spending, borrowing and taxation are huge. How does it happen that the state has been faced with budget adjustments of this size on four different occasions this decade? It stretches credulity to lay the blame solely on irresponsible spending. Rather, spending is typically multi-year and implicit in the approval of spending is a forecast of revenues sufficient to sustain that spending. 2 The systemic volatility in California’s revenues make these revenue forecasts unreliable. In this chapter, the source of that systemic problem is analyzed. One solution to alleviate volatility in California tax revenues is proposed. The solution proposed is clearly not the only route to less volatility, but rather a vehicle to demonstrate what must be done if California is to avoid a continuation of the repetitive severe revenue shortfalls of the 2000s decade and earlier.

property tax per se. There are certain levies which flow through the state government, but they are not revenue sources for state expenditures. These are included in the Census data and incorporated here for completeness. (It appears that the so-called “car tax,” a kind of property tax on motor vehicles, is treated in these data as California state revenue, although the state remits the proceeds to local governments.) As can be seen from Figure 1, for all but a handful of states, property taxes are insignificant. 1 1 One could argue, correctly, that state finance and local finance are difficult to separate. What happens in local government finance affects the state budget indirectly even if there is no direct linkage. Looking at property taxes across the country, we find that local governments typically rely on property taxes for the majority of their revenue. California’s property tax reliance is lower than the national average, but not by much, although about 2/3rds of the states rely more heavily than Cali-

SALES AND I N C O M E TA X E S There are two other important taxes to examine as potential sources of recurrent revenue problems in California: sales and use taxes and income taxes. Sales and use taxes are a major source of revenue for many states. This tax tends to be volatile because it relies heavily on consumer durables such as automobiles, home improvements, and home construction. While the sales tax in California is a major source of revenue, accounting for about 35% of state tax receipts, California is in the bottom quintile of states relying on this revenue source. So the answer to California’s recurrent budget crises does not seem to lie in sales and use taxes. If this were the problem, then the state would not be continually making the top-10 list for states with fiscal stress.

The last tax we want to examine for volatility is the income tax. In general, state income taxes are more variable and less predictable than other taxes.

California relies heavily on income taxes for its revenue generation, fifth in the nation. In the top-10 states measured by reliance on income tax about half appeared once on the stress list for either fiscal 2008 or fiscal 2009. The correlation is not perfect, but there is at least some indication that reliance on income taxes might be causal to swings in tax revenues. We should note that there are quite a few states on the stress list which have average or less-than-average reliance on income taxes as well. This fact just points out the difficulty of ferreting out California’s atypical shortfall situation. State tax revenue structures not only differ widely from each other and over time, and so does the character of their tax base.

R E F O R M I N G T H E TA X SYSTEM: A MODEST PROPOSAL Even though Prop 13 is clearly not the cause of California’s recurrent budget crises, wouldn’t elimination of Prop 13 give the legislature more tools to fix the problem? The answer is decidedly no. What Prop 13 does is stabilize the property tax base. With restrictions on the annual increase in assessed property values limited to the rate of inflation or 2%, whichever is lower, most properties in California will not be reassessed upwards to market values during boom times in the housing market. Nor will they be reassessed downward as market values fall during bust times. Under Prop 13, only properties actually sold are reassessed at current market value. Over long periods, housing will likely appreciate
preserve the stability of the tax base. This increase would move the mill rate up to a higher rate, but in the spirit of Prop. 13 prohibit it from rising year to year. Since the current property tax is a local levy, the added revenue from the rate increase would have to be redirected in some fashion to the state’s general fund. The second provision of tax reform would then be to lower income tax rates for each income tax bracket. The combination—increased tax revenue from a more stable base and decreased tax revenues from a less stable base—will decrease the overall volatility of the total tax revenue. To see the impact of this approach, consider the following exercise. Over the period 1990 to 2006, reduce all income tax brackets by 40%. To compensate for this raise the mill rate for property taxes from 100 to 170 and redirect the added revenue to the state’s general fund. Finally, keep all provisions of the tax code including Prop 13 restrictions on assessed value in place.
at a rate higher than the rate of inflation and, therefore, higher than the Prop 13 limited increase in assessments. A home is an investment as well as
CHARTING THE R E S U LT
a provider of shelter services. As an investment, it needs to earn an effective inflation-adjusted rate of return (after taking account of tax benefits and depreciation) at least as great as the next best alternative. Prop 13 actually stabilizes the revenue base and is thus a potential solution to California’s revenue crises.
This simple shift of the source of some of the revenue for the general fund would have had a dramatic effect on the volatility of the taxes throughout the 1990-2006 period. But the shift is revenue neutral in the sense that the aggregate amount of taxes collected in the hypothetical example is virtually identical to the actual

tax collected. We can see the results clearly in the volatility analysis of Figure 8. The volatility of California’s general revenue shrinks dramatically (the size of the lined sphere in the chart labeled CA**, relative to the size of the CA sphere in the upper right-hand corner). In fact, due to the stability of the Prop 13 protected annual increases in property tax revenue, the volatility falls much more

The year 2009 was rough. The national economy contracted by close to 4% from the second quarter of 2008 to the second quarter of 2009. This was the single worst pullback in GDP over the course of one year since the 1930s. The downturn was led by a 28% decline in business investment, and a 1.7% decline in real consumer spending. But now the recession is over, or so said Newsweek on the cover of its July 27, 2009 edition. Good news indeed as far as it went. In this chapter, we first review the national economic outlook. California is roughly an eighth of the national economy and cannot remain isolated from overall U.S. trends. We then turn to the specifics of the California outlook It is true that the third quarter of 2009 saw the U.S. expand at a pace in the 3 to 4% range, based on preliminary numbers available at this writing. That was a good number, driven by across the board gains. There were small gains in housing, a surge in consumer durables spending driven by the “cash-for-clunkers� program, government subsidized new car purchases for old-car trade-ins, rationalized by improved gas mileage. There was also a slowing of the inventory burn-off. Business investment spending on equipment and software remained flat, although we continued to see economic losses in non-residential construction. That sure sounded as if the recession was over.
LABOR MARKET LAGS
Unfortunately, the labor markets did not agree that the recession was over—indeed the figures as of fall 2009 remained positively ugly. Unemployment hit 9.8% in September 2009; total job losses to that point came to 7.2 million (-5.2%) since the employment peak hit in December of 2007. But it was hardly surprising that the nation continued to experience the loss of jobs and increasing unemployment. Labor markets are typically lagging indicators, and given the economic turmoil of

The second stage of the current downturn was driven by a slowdown in consumer spending. Between 2007 and 2008 the weakness in construction and finance in the state spread to wholesale and retail trade, in addition to administrative services where temporary employment services lie. Then, in the 2009, the downturn shifted to a general economic malaise. Business spending contracted sharply as did exports. Suddenly the job losses shifted to manufacturing, information and profession services. Those local economies that had avoided the worst of the start of the downturn suddenly took a sharp hit. San Jose, for example, saw one of the largest increases in unemployment in the state over the course of 2009, as can be seen on Table 2. Problems in the consumer economy spilled over into the rest of the state’s economy during 2009. Everything from professional services to local government to information jobs, took a hit. The only stable sectors were state and federal employment, and education and health. While at this writing there is still positive job growth in this last category, it has slowed sharply.

When will the state start to pull out of the slide? As of late 2009, the rise in unemployment seemed to slow as did the rate of job loss. Payroll-based employment figures tend to miss turning points because of the methodology used to compile the estimates. So these figures may be overstating the problem. On the other hand, new claims for unemployment insurance remain quite high. Overall, there was a mixed message from labor-market indicators.

R E A L E S TAT E A N D CONSTRUCTION News from the residential real estate front was slightly better as of late 2009, although there are still problems to work through. The price bubble in California was one of the largest in the nation, with prices rising from a median of $150,000 in 1996 to $300,000 in 2003 to $500,000 in 2006. This era was a time of prosperity for the state. But even so, the increases implied that the
market. The three major home finance institutions, Fannie , Freddie, and the FHA, more or less dominated the conforming market during 2009. Yet Fannie and Freddie were propped up by quantitative easing on the part of the Federal Reserve—a strategy that will eventually need to be reversed to prevent inflation. As for the FHA—it has become the new subprime lender with a portfolio that is experiencing rapid increases in delinquencies. When the bailout finally becomes necessary, we can expect that these activities will be curtailed.

CALIFORNIA’S POTENTIAL This suggestion may sound Pollyannaish. But consider that California, as hard as it might be to believe, has been one of the growth engines of the U.S. economy over the past decade. Table 4 provides real growth rates for California’s economy by sector, relative to the nation overall, from 1997 to 2008. The table is full of surprises. Overall, the state economy outgrew the U.S. economy by one full percentage point annually
193
during this period (3.6% versus 2.7%). The state grew faster (or declined slower) than the nation in almost every sector. The state only underperformed relative to national averages in three categories: logistics, administrative services, and management of companies and enterprises. This first sector may be a shock to those who have envisaged the Ports of Los Angeles and Long Beach as large drivers of growth in the economy. The greatest contributor to growth during this period was durable goods manufacturing, which accounted for almost one-fifth of California’s output growth. Manufacturing, particularly in information technology, is doing well despite the decline in jobs. This seeming paradox is explained by the substitution of capital, particularly computerization, for labor. Following manufacturing is real estate (the rental side, not the construction portion of the business), professional services, information, and retail trade. Real gross state product is not the only place we can see the success of the California economy. Personal income overall and per capita income have been growing faster here than in the nation overall, as have payroll employment and population growth. Why? Many reasons. The state is ideally located to take advantage of expanding trade with Asia and South America. It has a climate and a landscape that draws tourists and long-term residents to the state. It is home to some of the finest technical schools in the world that spin off many enterprises. And it is the center of two of the most important industries in this digital age: entertainment and information technology. The past is the past and the future is the future. While we have succeeded well prior to the Great Recession, that fact is no assurance of future growth. To understand this point, we have to consider the nature of the downturn.
194
ADVERSE SHOCKS There are two types of changes that can affect the growth of a regional economy. The first is a cyclical hit caused by a temporary pullback or an over-expansion in growth that has been caused by some change in exogenous demand conditions. Once the imbalance works its way through the system, the economy moves back onto a normal long-run trend and begins to grow at a normal pace again. The second type of shock is structural - when an industry that is important to a local economy is permanently downsized. When a structural shock occurs, it can take years for an economy to find steady footing and fill the hole left by the collapsed industry. In short, the long-run trend line is altered. The 2001 downturn was of the first type. During the late 1990s, a tremendous amount of capital poured into California chasing the pipe dream of the “New Economy.” This heated up the state’s economy to an unsustainable level, particularly in the San Francisco Bay Area. Unemployment fell to almost zero, as incomes reached ridiculously high levels. It was almost as if there was a new gold rush. Unfortunately, when the gold ran out, the economy went through the typical painful process of withdrawal.
But nothing fundamental had changed in the state. Information technology is still one of the most important growth industries in the world economy and the Bay Area is still the capital of that world. Once things returned to proper levels, growth continued. Most of the “decline” in the state was nothing more than a return to the long-term stable growth path—as can be seen on the chart of real income generated in California. Similarly, the downturn in the early 1980s was also cyclical, although here it was a negative cycle. The overall U.S. economy contracted and the reduction in demand caused the California economy to suffer losses. But the hit was temporary, and once the recession was over, the economy started to grow again at a rapid pace—until it caught up with its normal long-run growth trend. Figure 10.

Between 1993, when the bubble began, and 2002, when it reached its peak, the real value of the U.S. dollar rose by 32% compared to the rest of the world. This development was largely a cause of the widening trade gap. And this was not good for California. We are an export-heavy state—both from a goods perspective (particularly in information technology) and a services perspective (tourism and intellectual property licensing). A weak dollar helps California in exporting.

Key Takeaways
- Native Docker on Windows (supported by both Microsoft and Docker, Inc.) is available on Windows Server 2016 and Windows 10
- While Windows containers have a larger footprint than Linux, they are still roughly 10x more efficient than VMs because container processes run directly on the host server
- Docker has a positive cultural impact as dev and ops teams start sharing not only artifacts - Dockerfiles and Docker images – but a common language and tools
- Feature parity across Windows and Linux containers is expected by the end of 2017 - Microsoft is working on reducing the size of the base images and extending networking capabilities
- Any Windows application which you can install and run without a UI should be able to run in Docker – many organizations are migrating applications from old versions of Windows (e.g. from Server 2003) to run on a modern, supported version such as Server 2016
These are still early days for Docker on Windows but the possibilities in terms of workloads keeps growing.
InfoQ spoke with Elton Stoneman, author of the book Docker on Windows, and speaker at the recent WinOps conference, to understand how to run containers on Windows and which kind of workloads are a good choice for migration.
InfoQ: Could you briefly introduce yourself, what you do and what brought you to the world of containers?
Elton Stoneman: Sure. I'm an Azure MVP and a Pluralsight author - and I spent 15 years consulting before I joined Docker. My background is in Windows and .NET programming, typically large server-side applications using ASP.NET, WCF, Web API and SQL Server. I was working on a big Azure project in 2014, providing APIs to support an Android device. It was a cross-platform project, and the Linux team were using Docker to run their dev tools. I got interested, started using Docker a lot, started blogging and speaking about Docker and got invited to join the Docker Captains program (the Docker equivalent of Microsoft MVPs). Then a Developer Advocate role came up at Docker, Inc. and gave me a chance to focus 100% on Docker and the Microsoft ecosystem, and that's what I'm doing now.
InfoQ: Could you tell us what's the current status of "native", so to speak, Docker on Windows?
Stoneman: In container terms "native" means the application in the container uses the operating system of the host. If you run ten ASP.NET apps in Docker containers, you'll see ten instances of `w3wp.exe` in the task list on the server. The containers are still isolated units, and each app thinks it's on a separate server - with a hostname and an IP address - but it's the container processes which are isolated from each other. That's what makes Docker so efficient, running lots of containers on your server is just like running lots of apps on your laptop. Windows Server 2016 supports native Windows containers, and Docker Enterprise Edition is included in the Windows Server 2016 licence, so you get production support for your containers from Microsoft and Docker, Inc.
InfoQ: Does the Docker host for Windows-based Docker containers have to run a specific Windows OS?
Stoneman: You can only run Windows containers with process isolation on Windows Server 2016, and that can be on bare metal or VMs, on-prem or in the cloud. On the desktop, you can run Docker Community Edition on Windows 10. That uses a different isolation model (where each container runs in its own Windows Server 2016 kernel), but the way you run and manage containers is the same as on the server.
InfoQ: Windows typically has a larger memory and resources footprint than Linux, so isn't there a risk of ending up running "fat containers" that very much resemble a virtual machine?
Stoneman: There are differences between Windows and Linux containers, but Windows containers are still much more efficient than VMs. A Linux container could use Alpine Linux as the base (which is a 10MB operating system), and run the application in a single process. A Windows container might use Windows Server Core as the base (which is a 10GB operating system), and the application process will run alongside several background Windows services in the container.
But that Windows container is still running the processes directly on the host server, there's no heavyweight VM in between the app and the compute resources. Typically we see customers get between 5X and 10X efficiency - so a server that can run 10 VMs could run 100 containers. Lots of Docker customers are seeing an immediate return on investment when they move to containers, because they can decommission a lot of servers or cloud VMs.
There are storage efficiency gains, too. You package your application into a Docker image, which is a complete snapshot of one version of your app, with all its dependencies, configuration and application runtime. Images are split into layers which are shared, so if you have those ten ASP.NET apps packaged in Docker images, they all share the same 10GB Windows Server Core base image - only the delta between images is physically stored.
InfoQ: Can you briefly guide us through the biggest hurdles and critical milestones so far for Docker on Windows, both from technical and possibly cultural point of views?
Stoneman: The biggest cultural challenge is that this is a new way of running applications, and there is a learning curve for engineers and operations teams. But you can get started with Docker very quickly, and you soon see the benefits from having all your apps built, distributed and managed in the same way. The move to Docker often has a positive cultural impact. Dev and ops teams start working together on a common set of artifacts - Dockerfiles and Docker images - so they start talking the same language and using the same tools, and that can really help in the move to DevOps.
Technically, there are still some features of Docker that are Linux-only, but there's a lot of work going into the next update of Windows Server, so by the end of 2017 we should have pretty much parity across Windows and Linux containers. The biggest investment companies need to make is in writing the Dockerfile to package their applications, and integrating Docker into their CI/CD process. Tools like Jenkins, TFS and VSTS all provide Docker support. The outcome is usually a much cleaner, simpler workflow, which makes it easy to deploy updates automatically, but it does take some work to get there.
InfoQ: Docker was built upon Linux kernel isolation features such as cgroups and namespaces. How does this translate in the Windows world?
Stoneman: Those core Linux features have been around for a very long time, and Docker built on them to make containers easy to use. They've never existed in Windows, but when Microsoft people were working on Windows Server 2016 they wanted to add support for containers on Windows. The engineering teams at Microsoft and Docker worked together to add that support. The implementation is different from Linux, but it exposes a similar API so that Docker can manage containers in the same way. If you want to learn about the internals, there's a great talk from Microsoft at DockerCon 16 which goes into detail.
InfoQ: What types of Windows workloads can be safely migrated to Docker today? Do you have real world examples you could share?
Stoneman: Any Windows application which you can install and run without a UI should be able to run in Docker.
We usually work with clients who are "dockerizing" their own applications - from older ASP.NET WebForms apps, to new Go applications. Docker doesn't impose any restrictions on the style of the application, so you can have a monolithic web app running in a Windows Server Core container, and a microservices app running across multiple Nano Server containers, all running on the same cluster. We have a number of clients who are using Docker to migrate from older versions of Windows (think Server 2003). Then they can move to the cloud or on to modern infrastructure.
At Microsoft Ignite we had sessions with customers walking through their Docker journey - MetLife and Fox are real-world examples. You can also package off-the-shelf applications to run in Docker containers, provided you can script the installation. There are some server workloads which you definitely can't run in Windows containers – Microsoft Message Queuing (MSMQ) is one example - because the Windows Server Core image doesn't support it.
InfoQ: Who is working on and what is the roadmap for expanding support to more Windows workloads?
Stoneman: Microsoft's main focus for Windows containers is reducing the size of the base images, and extending the networking capabilities of Windows Server, so we'll get closer to parity between Docker on Linux and Docker on Windows. Microsoft maintain images on Docker Hub for some of their key workloads: SQL Server, ASP.NET and .NET Core. There are also official images on Docker Hub, which are trusted apps curated by Docker and the product teams. These are mostly Linux right now, but you can run Java apps with the Windows OpenJDK image, and the NATS message queue also has Windows images.
Anyone can package a Windows app into a Docker image and publish it on Docker Hub (if the product licence allows for that), so we will see a lot more open-source projects providing a Windows Docker image. Publishing an image on Docker Hub (or Docker Store if it's a commercial app) makes it very easy for users to try your app - all they need is Docker, everything the app needs to run is there in the image.
InfoQ: How does Windows licensing work for containers?
Stoneman: Windows licensing applies at the host level, so you pay for the number of servers or VMs running Windows. You don't need a licence for a Windows Server container, so if you can run 100 containers on one server, you only pay for one Windows licence.
InfoQ: What is your recommended roadmap for adopting Docker on Windows, starting from zero? What kind of considerations are needed in terms of infrastructure/applications as well as process and skills?
Stoneman: If you want to learn the basics then my talk from WinOps Docker on Windows: The Beginner's Guide is a good place to start. It covers the key concepts you need to know: Dockerfiles, images, registries, containers and orchestrators. Then if you want to get hands-on, you'll find the content for my Docker on Windows workshop on GitHub, which you can follow along to see how to move existing applications to Docker, and how that puts you in a good position to modernize them.
After that you should be ready to run your own proof-of-concept and move one of your existing apps to Docker. Start simple - an ASP.NET web app without too many integrations is a good choice, and you should be up and running in Docker in a day or two. For larger organizations Docker, Inc. can help run the PoC with the “Modernize Traditional Applications” program. And of course you should get a copy of my book, Docker on Windows.
InfoQ: In your talk you mentioned a helper tool called "image2docker", can you briefly explain what it does? Are there other tools to help migrate to Docker?
Stoneman: Image2Docker is a PowerShell tool that migrates existing applications to Docker. It's targeted for ASP.NET apps right now, and it can connect to a remote machine, or a virtual machine disk, extract the application content from the source and build a Dockerfile to package that app as a Docker image. It's a good starting point for seeing how your app runs in Docker, and we use it for PoCs when we're working with clients who have an existing suite of apps that they want to move to Docker.
Image2Docker is the only tool I know of that converts a deployed application to Docker, but a lot of IDEs have Docker support built-in for source code. Visual Studio 2017 has the highest feature set for adding Docker support to an application. It generates the Dockerfile to package the application image, and you can run the app in a container through Visual Studio and debug the app just as though it was running locally.
InfoQ: Will a Windows IT person be able to leverage Docker without any Linux knowledge?
Stoneman: Absolutely. Docker is cross-platform and it runs in the same way on Linux, Windows, IBM mainframes and the Raspberry Pi. If you only run Windows containers, you don't need to learn any Linux. You'll need to learn the basic Docker commands (like `docker image build` and `docker container run`), and how to package your application in a Dockerfile. The Dockerfile syntax is very simple, and mostly you'll be writing PowerShell or batch commands for the actual deployment in the Dockerfile, so you don't need to learn a lot of new stuff.
InfoQ: Do you think Docker on Windows will be a step forward in breaking down OS-level silos (the "Windows IT" vs the "Linux IT") in large organizations? Or will those two parallel skillsets still be needed?
Stoneman: All containers look the same to Docker, whether you're running a Go application in a Linux container, or an ASP.NET WebForms application in a Windows container. You can only run Linux containers on Linux servers and Windows containers on Windows servers, but you can join multiple Linux and Windows servers into a single cluster and manage all your workloads in the same way. Docker Enterprise Edition is very attractive to companies with diverse workloads for that very reason - you have a single pane of glass to manage all these apps. You build, deploy, scale, update, secure and administer them all in the same way using the same tool.
For IT teams Docker makes it very easy to work with apps from "the other side". Windows developers can add analytics to their apps by running Elasticsearch and Kibana in Linux containers. Linux admins can build a CI/CD pipeline for SQL Server databases running in Windows containers. I think we will get to the point soon where it doesn't really matter what's inside the container, from a user perspective. Maintainers will still need to know the internals to package the most efficient and secure images, but I'm sure the tooling will evolve so that becomes a simple task too.

I have tried (and Failed) to install SimpleCV multiple times
I am new to Python and SimpleCV, but I'm working from some textbooks, and I keep trying different ways to install and it keeps giving me warnings.

Thanks Tim,
I'm new to the group. Does this mean that most of the development is done
on Linux? This might be a Windows (Microsoft) -specific issue.
My tools are not that good, though I'll spend some time later today or
tomorrow to better understanding what I'm seeing. All I know is that the
most basic dump of leaked memory indicates quite a few problems in the
Visual Studio environment. I'm guessing this to be the same issue that I'm
bumping up against in my program.
If there's anyone else who has useful Windows tools, any effort would be
most helpful. I've described my changes to the program below.
Richard
---------------------------------
What I have done is put the following the declarative section of the program
(line 41, after #includes):
#ifdef _DEBUG
#ifndef DEBUG_NEW
#include <stdlib.h>
#include <crtdbg.h>
#define _CRTDBG_MAP_ALLOC
#define DEBUG_NEW new(_NORMAL_BLOCK, __FILE__, __LINE__)
#define new DEBUG_NEW
#endif
#endif
And then the following at the bottom of main():
#ifdef _DEBUG
_CrtDumpMemoryLeaks();
#endif
In reality the first change needs to be installed in all the ActiveMQ-cpp
source code, but I haven't reached that point yet. This is a simplistic
approach to instruct the memory allocator to track memory usage and then to
dump the display leakage. (google for more details.)

Hello friends, I hope you all are doing great. In today’s tutorial, I am going to give you a detailed introduction to the C++ Programming language. In cross-platform programming languages, C++ is the most popular that can be used to work on low and high-level applications. Bjarne Stroustrup was the founder of C++. He modified C language to develop C++ language. Control over system resources and memory can be attained by using C++. In 2011, 2014, and 2017 it was modified to C++11, C++14, and C++17. C++ is a middle-level language. It is advantageous to both programming languages low-level (drivers, kernels) and higher-level applications (games, GUI, desktop apps etc.).
Uses of C++
C++ is one of the world’s most famous programming languages. It is used in today’s OS, embedded systems and GUIs. It provides a clear structure to programs, permits codes to be reused and lowering development costs as its an object-oriented language. Since it is portable and can be used to create applications that can be used on multiple platforms. It is very easy to learn. As it is close to C# and Java, so switching to C++ or vice versa is very simple.
It is used in
- Operating systems e.g. Linux-based OS
- Browsers like UC browser, chrome, opera and firefox.
- Games and graphics e.g. Photoshop
- Clouds like Dropbox
- Database engines like reedit
Features of C++
Rich library support:
- It is a simple language as programs can be split into logical units and parts. It has rich library support and many data types.
Platform Dependent and Machine Independent:
- It is machine-independent but platform-dependent. It does not run on windows but is executable on Linux.
Middle-level language:
- It is a middle-level language as we can do both low-level programmings(drivers, kernels, networking etc.) and build large-scale user applications (Media Players, Photoshop, Game Engines etc.) as a high-level language.
3rd party libraries:
- C++ has rich library support as well as 3rd party libraries (e.g. Boost libraries) for easy, smart and rapid development.
Fast execution:
- For C++ speed of execution is very fast because it is compiled and highly procedural language.
- Garbage-collection, dynamic typing etc. slow the execution of the program overall. Since there is no additional processing in C++ so it is fast than others.
Provides direct Memory-Access:
- It provides pointer support to manipulate storage addresses. This helps in low-level programming ( indirect control over memory addresses).
Object-Oriented language:
- It is better than C with respect to object orientation that helps it to maintain extensible programs so large-scale applications can be built easily.
- Its friends and virtual features violate some important rules rendering it a completely object-oriented language.
Amazing facts of C++:
Some interesting facts about C++ are listed below
- C++ name tells us that C language modified with ++ incremental operator is C++ language
- The most famous language C ++ is used in commercial software.
- Four primary features of OOP are supported by C++
- Inheritance
- Encapsulation
- Abstraction, and
- Polymorphism
- From Simula67 Programming language C++ gained the features of OOP.
- For a C++ program to execute(at least main() function) , a function is the least requirement.
Basic concepts of C++ :
Basic concepts like syntax, variables, loop type etc will be discussed here.
Syntax of C++:
Here is the C++ basic program
#include <iostream.h>
using namespace std;
int main()
{
cout << “Hi this is C++”;
}
- iostream is a header file and provides us with input & output streams.
- namesspace std tells the compiler to use standard namespace. It can be used in 2 ways.
- the return type of main () is int.
- count << is used to print anything on the screen.
- // is used to add single comment. For multiple comments /*multiple comments*/ is used
Data types in C++:
There are built-in as well as user-defined data types in C++.
- In C++, classes are user-defined data types.
- Built-in data types are int, float, double etc.
- Derived data types are Array, function, pointer and reference.
C++ Program to get a sum of 3 numbers
//Program to receive three integer numbers and display their sum
#include <iostream>
using namespace std; int main()
{
int num1, num2, num3, Sum;
//variables num1, num2, num3 and sum are declared as integers
cout << “\n Enter Number 1: “;
cin >> num1;
cout << “\n Enter Number 2: “; cin >> num2;
cout)<< “\n Enter Number 3: “; cin>>num3;
Sum = num1 + num2 + num3;
cout << “\n The sum of ” << num1 << num2 “ and ” << num3 << ” is ” << Sum;
}
Modifiers in C++
In C++, special words(called modifiers) are used to modify built-in data types. There are four main data type modifiers in C++, they are:
- Long
- Short
- Signed and
- unsigned
These modifiers are with built-in data types to make them more precise and for expanding their range.
- long and short modify the maximum and minimum values that a data type can hold.
- Signed types include both +ive and _ive numbers as is the default type.
- Unsigned, numbers do not have any sign, so they are always positive.
Variables in C++ :
- Variable is used in C++ to store any value, which can be changed in the program.
- Variable is declared in many ways each with different memory location and functioning.
- It is the name of the memory location allocated by the compiler to the variable.
Variables are divided into two main types,
- Global Variables
- Local variables
Global variables
Global variables are those which declared only a single time and used again and again. They are declared outside the main() function. If only declared then assigned different values at different times in program lifetime. But when they are declared and initialized at the same time then they can be assigned any value at any point in the program.
For example: Only declared, not initialized
include <iostream>
using namespace std;
int x; // Global variable declared
int main()
{
y=10; // Initialized once
cout <<“first value of y = “<< y;
y=20; // Initialized again
cout <<“Initialized again with value = “<< y;
}
Local Variables
- Local variables exist only between the curly braces, in which they are declared.
- Outside the curly braces, they are unavailable and lead to a compile-time error.
Example :
include <iostream>
using namespace std;
int main()
{
int j=10;
if(j<20) // if condition scope starts
{
int m=100; // Local variable declared and initialized
} // if condition scope ends
cout << m; // Compile time error, m not available here
}
C++ Program to find the curved surface area of a cylinder (CSA) (CSA = 2 pi r * h)
#include <iostream>
using namespace std;
int main()
{
float pi = 3.14, Radius, Height, CSA;
cout << “\n Curved Surface Area of a cylinder”;
cout << “\n Enter radius (in cm): “;
cin >> Radius;
cout << “\n Enter height (in cm): “;
cin >> Height;
CSA = (2*pi*Radius)*Height;
system(“cls”);
cout << “\n radius: ” << Radius <<“cm”;
cout << “\n height: ” << Height << “cm”;
cout << “\n Curved Surface Area of a Cylinder is ” << CSA <<” sq. cm.”;
}
Output:
- Curved Surface Area of a cylinder
- Enter radius (in cm): 7
- Enter height (in cm): 20
- radius: 7cm
- height: 20cm
- The curved Surface Area of a Cylinder is 879.2 sq. cm.
Operators in C++ :
- Operators take one or more arguments and generate a new value.
- For example : addition (+), subtraction (-), multiplication (*) etc, are all operators.
- These are used to perform different operations on variables and constants.
Errors in C++:
There are three types of errors that occur in C++ programming
Syntax Error:
- The syntax is a set of grammatical rules to make a program. Every programming language has unique grammatical rules.
- when grammatical rules of C++ are violated Syntax Errors occur.
- For example: if you type as follows, C++ will throw an error.
cout << “Hi welcome to C++”
- As per the grammatical rules of C++, there should be a semicolon at the end of the statement. But, this statement does not end with a semicolon so Syntax Error occurs.
Logical Error:
It may be happened by the wrong use of variable or operator or order of execution etc. This means that the program is grammatically correct, but it contains some logical errors. So, “Logic Error” is also called Semantic error.
Run time error:
- During the execution of the program when some illegal action takes place, run time error occurs
- For example, if a program tries to open a file that does not exist then it will result in a run-time error.
Control Statements in C++:
- The sequence of flow of instructions is changed by the use of control Statements.
Selection statement
- Statements can run sequentially, selectively or iteratively in a program. Sequence, selection and iteration processes are handled by every programming language.
- If the statements are executed sequentially then the flow is called a sequential flow. In some situations, if the statements alter the flow of execution then this flow is called a control flow.
Sequence statement
- The sequential statement is executed one after the another only once from top to bottom.
- These statements do not alter the flow of execution and are called sequential flow statements. These statements always end with a semicolon (;).
Selection statement
- When a condition is provided then selection statements are used.
- In case when the condition is true then a true block (a set of statements) is executed otherwise a false block is commanded to execute.
- This is also called a decision statement because it helps in making decisions for the set of statements to be executed.
- Selection statements are if, if-else and nested if statements.
if statement
- The general syntax of the if statement is:
if (expression)
true-block;
statement-x;
- and flow chart for if statement is
if-else statement
- The syntax of the if-else statement is given below:
if ( expression)
{
True-block;
}
else
{
False-block;
}
- And the flow chart for if-else statement is:
C++ program to find either number is Even or Odd
#include <iostream>
using namespace std;
int main()
{
int Num, rem;
cout<< “\n enter a number: “;
cin>>Num;
rem = Num % 2;
if (rem==0)
cout<< “\n The given number” <<Num<< ” is Even”;
else
cout<< “\n The given number “<<Num<< ” is Odd”;
return 0;
}
Output
- Enter number: 12
- The given number 12 is Even
Nested if
It has three forms
- If nested inside if part
- If nested inside else part
- If nested inside both if part and else part
Iteration statement
- The iteration statement is a set of statements that are executed again and again depends upon conditions.
- If a condition evaluates to true, the set of statements (only true) is executed again and again.
- As soon as the condition seems to be false, the repetition stops. This is also known as looping statement
- The set of statements that are executed repeatedly is called the body of the loop.
- The condition on which exits from the loop is called exit-condition or test-condition.
- There are 3 kinds of loops in C++
- For loop
- While loop
- Do while loop
for loop
- The for loop is the easiest loop which allows code to be executed again and again.
- The general syntax is:
for (initialization(s); test expression; update expression(s))
{ statement 1;
statement 2;
………….
}
C++ program to sum from 1 to 5 using for loop
#include <iostream>
using namespace std;
int main ()
{
int i,Sum=0;
for(i=1; i<=5;i++)
{
sum=sum+i;
}
cout<<“The sum of 1 to 5 is “<<Sum;
return 0;
}
Output
- The sum of 1 to 5 is 15
While loop
- It allows the loop statements to be executed as long as the condition is true.
- The while loop syntax is:
while ( test expression )
{
body of the loop;
}
- Flow chart for while loop is given below
C++ program to sum from 1 to 6 using while loop
#include <iostream>
using namespace std;
int main ()
{
int i=1,SUM=0;
while(i<=6)
{
SUM=SUM+i;
i++;
}
cout<<“The sum of 1 to 6 is “<<SUM;
return 0;
}
Output
- The sum of 1 to 6 is 21
do-while loop
- The do-while loop is used as an exit-controlled loop. In a do-while loop, after executing the body of the loop, the condition is evaluated.
- The do-while loop syntax is:
do
{
body of the loop;
} while(condition);
- The flow chart of the do-while loop is shown below
Examples of C++ programs:
1. C++ Program to find the Total marks of three subjects
#include <iostream>
using namespace std;
int main()
{
Int n1, n2 , n3, Sum;
cout << “\n Enter Mark 1: “;
cin >> n1;
cout << “\n Enter Mark 2: “;
cin >> n2;
cout << “\n Enter Mark 3: “;
cin >> n3;
Sum = n1 + n2 + n3;
cout << “\n The sum = ” << Sum;
}
2. C++ program to find the Area of a Circle
#include <iostream>
using namespace std;
int main()
{
int Radius;
float Area;
cout << “\n Enter Radius: “;
cin >> Radius;
Area = 3.14 * Radius * Radius;
cout << “\n The area of circle = ” << Area;
}
So, that was all for today. In the next tutorial, we are going to discuss the Data Types in C++ in detail. If you have any questions regarding this tutorial, ask in the comments.

HTTP/2 Client for Python
Project Description
HTTP is changing under our feet. HTTP/1.1, our old friend, is being supplemented by the brand new HTTP/2 standard. HTTP/2 provides many benefits: improved speed, lower bandwidth usage, better connection management, and more.
hyper provides these benefits to your Python code. How? Like this:
from hyper import HTTPConnection conn = HTTPConnection('http2bin.org:443') conn.request('GET', '/get') resp = conn.get_response() supports the final draft of the HTTP/2 specification: additionally, it provides support for drafts 14, 15, and 16 of the HTTP/2 specification. It also supports the final draft of the HPACK specification..
Documentation
Looking to learn more? Documentation for hyper can be found on Read the Docs.
v0.7.0 (2016-09-27)
Major Changes
- Added a ping method, allowing the user to use the HTTP/2 PING frame to check connection liveness before, instead of, or between issuing requests.
Bugfixes
- Don’t send WINDOWUPDATE frames on closed streams.
- Clean up the outstanding stream reads on stream close.
- Ensured that connection state is always unconditionally reset on stream close, regardless of whether the connection has a socket object open or not.
0.6.2 (2016-06-13)
Bugfixes
- Fixed packaging error made in prior release.
0.6.1 (2016-06-13)
Bugfixes
- Tolerate errors when attempting to send a RST_STREAM frame.
- Ensure that calls to fileno() on the compatibility SSLSocket object actually work correctly. Thanks to @benlast!
- Improved some problems with thread-safety in the Stream class. Thanks to @fredthomsen!
- Allowed for systems to use hyper without the bundled cert file being present. Thanks to @JasonGowthorpe!
0.6.0 (2016-05-06)
Major Changes
- The HTTP20Connection object is now thread-safe, so long as stream IDs are used on all method calls.
- Replaced the HTTP/2 state machine logic entirely to use hyper-h2. This will dramatically change the behaviour of the library in many situations, mostly for the better. However, this is also likely to introduce new bugs, so please be cautious.
API Changes
- Allow non-dictionary headers in request.
- HTTP20Connection now has a force_proto keyword argument to allow the HTTP20Connection to ignore the NPN/ALPN result.
- The --h2 CLI flag now ignores the result of NPN/ALPN negotiation when hitting HTTPS URLs.
- Added support for HTTPS client certificates.
- Notifications about streams being reset is now delayed to fire when the stream in question is next accessed, rather than immediately.
Bugfixes
- Overriding HTTP/2 special headers no longer leads to ill-formed header blocks with special headers at the end.
- Vastly improved IPv6 support.
- Fix converting unicode bodies to bytestrings on Python 2.7.
- Allow overriding the HTTP/2 pseudo-headers from the CLI.
- Fixed problems with incorrectly generating the HTTP2-Settings header.
- Improved handling of socket errors.
0.5.0 (2015-10-11)
Feature Enhancement
- Pay attention to max frame length changes from remote peers. Thanks to @jdecuyper!
Bugfixes
- Prevent hyper from emitting oversized frames. Thanks to @jdecuyper!
- Prevent hyper from emitting RST_STREAM frames whenever it finishes consuming a stream.
- Prevent hyper from emitting lots of RST_STREAM frames.
- Hyper CLI tool now correctly uses TLS for any https-schemed URL.
- Hyper CLI tool no longer attempts to decode bytes, instead writing them straight to the terminal.
- Added new --h2 flag to the Hyper CLI tool, which allows straight HTTP/2 in plaintext, rather than attempting to upgrade from HTTP/1.1.
- Allow arguments and keyword arguments in abstract version of get_response.
Software Updates
- Updated hyperframe to version 2.1.0
0.4.0 (2015-06-21)
New Features
- HTTP/1.1 and HTTP/2 abstraction layer. Don’t specify what version you want to use, just automatically get the best version the server supports!
- Support for upgrading plaintext HTTP/1.1 to plaintext HTTP/2, with thanks to @fredthomsen! (Issue #28)
- HTTP11Connection and HTTPConnection objects are now both context managers.
- Added support for ALPN negotiation when using PyOpenSSL. (Issue #31)
- Added support for user-provided SSLContext objects, with thanks to @jdecuyper! (Issue #8)
- Better support for HTTP/2 error codes, with thanks to @jdecuyper! (Issue #119)
- More gracefully close connections, with thanks to @jdecuyper! (Issue #15)
Structural Changes
- The framing and HPACK layers were stripped out into their own libraries.
Bugfixes
- Properly verify hostnames when using PyOpenSSL.
0.3.1 (2015-04-03)
Bugfixes
- Fix blocking ImportError. (Issue #114)
0.3.0 (2015-04-03)
New Features
- HTTP/1.1 support! See the documentation for more. (Issue #75)
- Implementation of a HTTPHeaderMap data structure that provides dictionary style lookups while retaining all the semantic information of HTTP headers.
Major Changes
- Various changes in the HTTP/2 APIs:
- The getheader, getheaders, gettrailer, and gettrailers methods on the response object have been removed, replaced instead with simple .headers and .trailers properties that contain HTTPHeaderMap structures.
- Headers and trailers are now bytestrings, rather than unicode strings.
- An iter_chunked() method was added to response objects that allows iterating over data in units of individual data frames.
- Changed the name of getresponse() to get_response(), because getresponse() was a terrible name forced upon me by httplib.
0.2.2 (2015-04-03)
Bugfixes
- Hyper now correctly handles ‘never indexed’ header fields. (Issue #110)
0.2.1 (2015-03-29)
New Features
- There is now a
hypercommand-line client that supports making HTTP/2 requests directly from the command-line.
Major Changes
- Support for the final drafts of HTTP/2 and HPACK. Updated to offer the ‘h2’ ALPN token.
Minor Changes
- We not only remove the Connection header but all headers it refers to.
0.2.0 (2015-02-07)
Major Changes
- Python 2.7.9 is now fully supported.
0.1.2 (2015-02-07)
Minor Changes
- We now remove the Connection header if it’s given to us, as that header is not valid in HTTP/2.
Bugfixes
- Adds workaround for HTTPie to make our responses look more like urllib3 responses.
0.1.1 (2015-02-06)
Minor Changes

I (Derrick) help administer several Python groups where I field countless questions each day. In this post I’ll answer the question I hear the most, “How do I get started with Python?”
(1).
Python Properties
Python is…
- Strongly typed. It enforces data types so you can’t concatenate a string and a integer, for example.
- Dynamically, implicitly typed. So, you don’t have to explicitly declare variable data types. Data types are enforced at runtime.
- Case sensitive. For example,
tokenand
TOKENare two different variables.
- Object-oriented. Everything is an object.
(2) Getting Python – A Prelim
Python is free, open-source software that works on Linux, Mac, Windows, and various other platforms (21 in total). It comes preinstalled on Mac and most distributions of Linux; however, you may need to download the latest version (see below).
To check your version, open the terminal and run the following command:
python -V
Choosing a Python Version
It can be confusing for both new and seasoned programmers on deciding between Python 2 or 3. Fortunately, there are few syntactical differences between the two and you can run both version on your computer.
Currently, there are two main versions of Python - 2.x and 3.x.
Only version 3.5.x is in active development, in terms of gaining new features and functionality, while Python 2.7.x as well as 3.2.x to 3.4.x are actively maintained.
Which version is right for you? Well, that’s up to you. Honestly, there are few differences between the two that will affect you at this early stage, so either choice will suffice. Plus, once you’ve learned one, it’s not too difficult to learn the other.
In general, if you’re just starting to learn Python, go with 3.4.x, since it’s a better version as there are added features along with plenty of bug fixes and refinements. However, 2.7x has much more support from third-party libraries. If you know you’ll need to use a library that has not been ported to version 3.4.x, then it may be best to start with 2.7x.
The examples in this series will be shown in version 3.4.2, which is the current version as of writing. That said, most of the examples will work fine with either version since many of the features and updates added to 3.4.x were also added to 2.7.x. We’ll discuss any differences that you should be aware of as they arise.
(3) How do I get Python?
Regardless of your operating system, you can download Python from the Python Software Foundation (PSF). Grab the version specific to your OS and processor (32 or 64-bit).
OS-specific instructions:
- Mac: I strongly recommend using Homebrew to install and manage different version of Python. Check out the directions here. You can also download Python from the PSF.
- Linux: Again, Python is included on various flavors of Linux. Be sure to upgrade to the latest version using the package manager, if necessary.
- Windows: Download Python direct from the PSF.
Windows users: Make sure you select the option to add Python to your system path during the installation process:
(From the drop-down select the option, “Will be installed on local hard drive”.)
(4) Confirming the Python Install
Let’s do a quick sanity check to ensure Python installed correctly.
Python Shell
Open the Python Interactive Shell:
- Mac: Open your terminal and run:
pythonor
python3, depending upon your installation.
- Linux: Open your terminal and run:
python
- Windows: If you have only one version of Python installed simply run
python. If you have both Python 2.7 and Python 3 installed, run
pythonfor Python 2.7 and/or
py -3for Python 3.
Windows users: Ensure that your account has administrative privileges: Run the command prompt at an elevated level by right-clicking the command prompt icon, and then selecting ‘Run as Administrator’.
The interactive Python Shell should open, and your command prompt or terminal window should look similar to this:
Python 3.4.1 (v3.4.1:c0e311e010fc, May 18 2014, 00:54:21) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>>
While you’re here, you might as well run your first line of code…
Python 2:
>>> print "Python is fun!"
Python 3:
>>> print("Python is fun!")
If you’re running Python 2.x, the
You should see:
Python is fun!
And that’s it: You’ve just written your first Python program! Each time you entered a line, Python immediately executed the statement, displaying the value between the quotes.
Once done, you can use
exit() to leave the Python Shell. Or:
- Mac and Linux users: Ctrl-D plus Return
- Windows users: Ctrl-Z plus Return
Keep your terminal or command prompt open. We still have more to do! Let’s continue using the Shell as we run through the Python primitives.
(5) Language Primitives
In this section we’ll look at the Python primitives - variables, built-in data types, comments, syntax, and semantics.
Variables
Variables are containers for data. The syntax to declare them is:
variable_name = variable_value. While you can name variables anything you’d like (except for a few reserved keywords), you should use a naming scheme that makes intuitive sense. The variable name should provide some indication as to what the values assigned to it are.
For example, many new programers, use simple variable names like
x and
y. Do (err, try) not to do this. Instead, if you have two numbers - say
1 and
52 - use the variable names
num1 and
num2 instead of
x and
y. That way when others read your program, they can make an educated guess that
num1 and
num2 are probably numbers of some sort. Think of others when writing your programs, as well as your future self. Your future self will thank you.
Built-in Data Types
Python has a number of built-in data types such as numbers (integers, floats, complex numbers), strings, lists, tuples, and dictionaries.
Each of these can be manipulated using:
- Operators
- Functions
- Data-type methods
Be sure to type each example out along with me.
Numbers
Numbers can be integers, floating points, Booleans, or complex numbers. The former three are the most important:
- Integers are whole numbers -
1,
2,
22,
476,
-99999
- Floats have decimal points -
1.0,
2.22,
22.098,
476.1,
-99999.9
- Booleans represent either
Trueor
False(or
1or
0). They represent data that can only be one thing or another.
Manipulating numbers
Operators
You’ve seen operators before. They’re things like addition (or concatenation) and subtraction, just like you learned in Elementary school.
>>> 2 + 3 # Addition 5 >>> num1 = 10 >>> num2 = 9.99 >>> num3 = num1 + num2 >>> num3 19.990000000000002 >>> 8 - 5 # Subtraction 3 >>> 2 * 6 # Multiplication 12 >>> 12 / 3 # Division 4.0 >>> 7 % 3 # Modulus (returns the remainder from division) 1 >>> 3 ** 2 # Raise to the power 9
Putting your pre-algebra skills to the test, let’s look at comparisons, which evaluate to boolean values - e.g., either
True or
False (or
1 or
0).
>>> 2 < 5 True >>> 4 > 10 False >>> 3 >= 3 True >>> >>> 5 == 6 False >>> 6 != 9 True
Functions
Python provides you with a number of built-in functions for manipulating integers. These are always available to you. Please note: These functions can be used on any data type. There are a number of modules available in the Python Standard Library as well, such as
math. To use the functions associated with these modules, you’ll first have to import the module. More on this later. For now, let’s look at a few examples of built-in functions.
float() - given an integer, this function returns a float.
>>> float(9) 9.0 >>> float(-99999) -99999.0
int() - given a float, this function returns and integer. This function does NOT round the input up (ceiling) to the nearest integer – it simply throws out anything after the decimal point (flooring) and returns the number. So the input of 10.6 returns 10, NOT 11. Similarly, 3.25 returns 3.
>>> int(10.6) 10 >>> int(3.25) 3
Data-type methods
Besides functions, there a number of data-type methods associated with each type of number.
float.is_integer() - tests if a float is finite.
>>> (10.0).is_integer() True >>> (10.1).is_integer() False
Strings
Strings are lines of text that are declared with single or double quotes:
>>>>> simple_string 'hey!' >>> "hello world!" 'hello world!' >>>>> escaped "can't" >>>>> not_escaped "can't"
Manipulating strings
Operators
Like numbers, you can concatenate strings (string concatenation):
>>> "happy" + " " + "birthday" 'happy birthday' >>> "my name is " + "john" 'my name is john'
Functions
Let’s look at just a few functions that are good to use for string manipulation:
len() - given a string, this function returns the length of it.
>>> len(name_string) 15
slice() - given a start and stop value, you can access a set of, or single, character(s).
>>> print("Hello"[2]) l >>> print("Hello"[3]) l >>> print("Hello"[0]) H >>> print("Hello"[0:2]) He
Data-type methods
While we’ll only touch on a few data-type methods, be sure to check out the full Python documentation as there are a number of important functions that you should be aware of.
string.capitalize() - returns the string with the first letter capitalized.
>>>>> lower_case_string.capitalize() 'Michael' >>> ("empire").capitalize() 'Empire'
string.format() - you can easily format values into strings.
>>>>> greeting = "My name is {}".format(name) >>> greeting 'My name is John Doe' >>>
string.strip() - returns the string with the leading and trailing whitespace removed.
>>>>> are_you_happy.strip() 'Yes'
Lists
Lists, which are called Arrays in nearly every other programming language, group various types of data together.
create_a_list = []
numbers_list = [1, 2, 3]
strings_list = ["spam", "eggs", "cheese"]
mixed_list = ["Hello", [1, 2, 3], False]
As you can see above, lists may contain any data type (you can mix and match, too), including other lists or nothing at all. You can access parts of lists just like strings with indexes. The syntax is the same:
>>> create_a_list = [] >>> create_a_list [] >>> numbers_list = [1, 2, 3, 200] >>> numbers_list [1, 2, 3, 200] >>> strings_list = ["batman", "superman", "iron man"] >>> strings_list ['batman', 'superman', 'iron man'] >>> mixed_list = ["Hello World", [4, 5, 6], False] >>> mixed_list ['Hello World', [4, 5, 6], False]
You can access elements from the list from either the beginning or end of the list:
>>> numbers_list[0] 1 >>> numbers_list[0:1] [1] >>> numbers_list[0:2] [1, 2]
Watch how you can create a new list just by accessing the elements:
>>> numbers_list = [1, 2, 3, 200] >>> new_list = numbers_list[0:3] >>> new_list [1, 2, 3]
Negative indexes count from the last item backwards:
>>> strings_list = ["batman", "superman", "iron man"] >>> strings_list[-1] 'iron man'
If you nest a list within another list, you can access the inner list using multiple indexes:
>>> mixed_list = ["Hello World", [4, 5, 6], False] >>> mixed_list[1][2] 6
Manipulating lists
Operators
Lists can be concatenated:
>>> fruits = ["apples", "grapes", "oranges"] >>> veggies = ["corn", "kale", "mushrooms"] >>> grocery_list = fruits + veggies >>> grocery_list ['apples', 'grapes', 'oranges', 'corn', 'kale', 'mushrooms']
Functions
In general, you can think of lists as strings - only each piece of data is an element. What does that mean in practical terms? Well, the same functions you use on strings can be used for lists.
len() - given a list, this function returns the length of it.
>>> numbers_list = [1, 2, 3, 200] >>> len(numbers_list) 4
slice() - given a start and stop value, you can access a set of elements.
>>> hello = ["H", "e", "l", "l", "o"] >>> hello[2] 'l' >>> hello[3] 'l' >>> hello[0] 'H' >>> hello[0:2] ['H', 'e']
Data-type methods
Again, check out the Python documentation to see all available list methods.
list.append() - used to add an item to the end of a list
>>> fruits = ["apples", "grapes", "oranges"] >>> fruits.append("blueberries") >>> fruits ['apples', 'grapes', 'oranges', 'blueberries']
list.sort() - sort this list
>>> fruits.sort() >>> fruits ['apples', 'blueberries', 'grapes', 'oranges']
list.pop() - given an index value, remove an element from the list
>>> numbers_list = [1, 2, 3, 200] >>> numbers_list.pop(2) 3 >>> numbers_list [1, 2, 200]
Tuples
Tuples are similar to lists, but they are immutable - which means they cannot be changed after creation.
my_tuple = ("Michael", "Herman", 31, "Software Developer")
Just like a list, you can also use indexes to access different elements:
>>> my_tuple = ("Michael", "Herman", 31, "Software Developer") >>> my_tuple[1] 'Herman'
Often tuples are used for dictionary keys since they should (err, must) be immutable.
Manipulating tuples
Operators
Yes, you can add two tuples:
>>> first_tuple = (1, 2) >>> second_tuple = (3, 4) >>> third_tuple = first_tuple + second_tuple >>> third_tuple (1, 2, 3, 4)
Functions
list() - used to convert a tuple to a list
>>> first_tuple = (1, 2) >>> list(first_tuple) [1, 2]
What about converting a list to a tuple? Is there a function for that? Where would you go to find out?
Data-type methods
Because tuples are immutable, many of the list methods don’t work on tuples.
>>> first_tuple = (1, 2) >>> first_tuple.append(3) Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'tuple' object has no attribute 'append' >>> first_tuple.pop(1) Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'tuple' object has no attribute 'pop' >>> first_tuple.sort() Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'tuple' object has no attribute 'sort' >>> first_tuple.reverse() Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'tuple' object has no attribute 'reverse'
Dictionaries
Dictionaries are a type of associative array (an object) implemented using hash tables containing key/value pairs. They are unordered.
my_dict = {"Key 1": "Value 1", "name": "michael herman", "pi": 3.14}
You can return a key’s value using the following syntax:
>>> my_dict = {"Key 1": "Value 1", "name": "michael herman", "pi": 3.14} >>> my_dict["name"] 'michael herman' >>> my_dict["Key 1"] 'Value 1'
Manipulating dictionaries
Research this on your own, using the Python documentation. Need help? Comment below.
Speaking of comments…
Comments are used to describe your code so other developers can quickly understand what’s happening (as well as your future self).
# This a comment on it's own line # You create them with the hash symbol var = "Hello" # They can also be on the same line as code
Need Help?
Like a good friend, Python is always available if you get stuck. Perhaps you want to know how a specific object works, simply open the Python shell and then call
help() to get help or
dir() to see which methods are available for that particular object.
(6) Coding in Python
There are three basic approaches to coding in Python. We already used one of them - the interactive Python Shell.
The Shell (redux)
This is the least powerful of the three. Although you can create functions in the Shell, typically it is reserved for simple, one-line statements to get quick feedback on your code.
For example, let’s look at a simple expression. Open the Shell and run:
>>> 24 + 10 34
The Python Shell simply evaluated
24 + 10, adding the two numbers, and outputted the sum,
34.
Try one more:
>>> import this
Take a minute to read the output. These are some important concepts in Python, which will help you write idiomatic Python code.
Close the Python interactive Shell. Once closed, our code is gone. In other words, the code typed into the Python Shell is not persistent - and cannot be reused. As coders, we want code that we can reuse to save precious keystrokes. Unfortunately, the Python Shell fails in this regard.
IDLE
Python comes with a program named IDLE (named after Monty Python’s Eric Idle). IDLE is interactive and can be used exactly like the Python Shell. It can also be used for code reuse since we can create and save Python code. That said, IDLE still is not as powerful as the last method, so we will skip it for now.
If you are interested in using IDLE check out the excellent guide One Day of IDLE Toying.
Code Editor
The best approach is to use an actual coding editor. Some people prefer an Integrated Development Environment (IDE), but a far simpler code editor is much better for learning purposes.
Why? When you are learning something new you want to peel off as many layers of complexity as possible. Simplify things. By adding a complex IDE into the mix, which you will have to learn how to operate, you are just adding more and more layers, making the task - learning Python - even more difficult.
(7) Picking a Coding Editor
A Python program, in its basic form, is simply lines of text (code) saved in a file with a .py file extension. Python code can be written in something as basic as Notepad - but there’s no reason to put yourself through such an ordeal since there are much better options available. At it’s core, a code editor should provide a number of features that help a programmer create programs (Python scripts and modules, in our case). In most cases, code editors allow the user to customize the program itself, to suit your needs and style.
What should you look for in a code editor?
- Ease of use
- Syntax highlighting
- Auto-indentation
- Tabbed views
- Line numbering
- Ability to customize the look and feel of the editor
- Availability of add-ons
Take a look at the following example:
So, not only is the code easier to read in the editor (Sublime Text) on the top (due to the syntax highlighting and line numbering), but it’s also identifying three simple errors, one of which is a show-stopper. (Can you figure out which one?) Meanwhile, the editor (Notepad) at the bottom does not display the errors and is hard on the eyes since it’s black and while.
Which editor should I use?
One of the most popular code editors is Sublime Text 3 (shown above). It is powerful, cross-platform, and free to try out.
Be sure to support the project by purchasing a license if you continue to use it.
If you want something simpler, check out gedit, which is also cross-platform. Notepad++ is also a great editor, but it’s for Windows only. Both of these editors are free and although neither possesses the power of Sublime Text, they are still useful.
A third option is Vim, which is free and available for Mac, Linux, and Windows. Vim has a steep learning curve but it has a loyal user base. Steve Francia’s Vim Distribution is the best programming setup for Vim that I have ever seen.
I personally prefer Sublime Text 3. Check out the blog post Setting Up Sublime Text 3 for Full Stack Python Development to see how to customize it specifically for writing Python code.
Remember: There are many different options when it comes to code editors, both free and commercial. Do your research, and don’t be afraid to experiment! Just remember: an editor should help you adhere to Python coding standards, practices, and idioms…
(8) Python Idioms = Happy Coding
PEP 8 – Style Guide for Python Code is the style guide for programming Python code. Study this.
One idiom that trips up many new Python developers is indentation. Python uses indentation (4 spaces) to logically organize code into sections called [code blocks](. A code block starts with an indent and ends with a dedent (un-indent?). Incorrect indentation will generate an error in Python preventing your code from executing. And this is exactly where having a properly setup code editor pays off, since it will catch indentation errors and highlight them for you. You should also use spaces instead of tabs when indenting. Most editors will allow you to convert tabs to spaces, so that when you tab it is actually applying 4 spaces.
Let’s revisit the errors from the above image…
- Line 2 - No space around the
<operator. As explained in PEP8, Python expects spaces around operators. This is not a critical error but problematic as your code should be clean and readable.
- Line 4 - There are two errors here, including the show stopper. As stated above, Python uses indention to define code blocks.
count = count + 1, is part of a block of code that starts on line 2, so that it must be indented 4 spaces in order for Python to include it in the code block.
(9) Counting to 10
Ready to dive into a basic example?!
If you are brand new to programming you may not fully understand the code but it’s the concepts that are important. Python is designed to read very easily and this example demonstrates that principle. We are going to fix the broken code above, and add one more code block to emphasize the concepts of code blocks and indentation.
Many programmers get overwhelmed when they initially approach a problem. An effective approach to help solve the problem, regardless of size, is to logically divide the problem into parts.
For example, let’s code a basic program that counts from 1 to 10. Each time the count increments we want to display a new number, and to help with the concept of code blocks we are going to show what happens after we reach 10. One approach to help in development of a workflow, is to use pseudocode.
Let’s Make a Plan (pseudocode!)
I like to keep things organized on my computer, so first create a folder, put it in your “documents” folder or someplace similar. I created a folder called,
python_code. Learning to code is hands on, so open up your code editor, and enter the following code. Do not copy and paste no matter how tempting it is. Doing so will hinder learning.
Python 2.7:
# Python 2.7 count = 1 # Code block 1 while count < 11: print count count = count + 1 # Code block 2 if count == 11: print 'Counting complete.'
Python 3:
# Python 3 count = 1 # Code block 1 while count < 11: print(count) count = count + 1 # Code block 2 if count == 11: print('Counting complete.')
Note that the first line of each example has a
# (hash character), followed by a space and then an explanation. This is an inline comment. Such comments have a number of purposes, but for the most part they are used to either explain code or summarize a specific approach a developer took. Do the comments in the above examples make sense to you? If not, change them.
Finally, as you will soon come to find out, comments are ignored by Python when the code is executed.
Did you notice that the examples use both single
=, and double
==? This can be confusing.
- n the expression
count = 1, the
=assigns the value of 1 to the variable named
count.
- In the conditional
if count == 11:, the
==compares the value of
countwith
11, returning a boolean
Trueor
False. Can you tell what the statement evaluates to in the above example after each iteration?
Save the file as count_to_ten.py in the folder you created then exit the editor. Open a terminal or command prompt and navigate to the folder you created.
Now run the code:
python count_ten.py
You may need to replace
pythonwith
python3or
py -3, depending on your setup. See Step 4 for more info.
And the output should look something like this:
Congrats! You just wrote your first program.
(10) Errors and Exceptions
Errors are something that irritate and frustrate programmers at every level of experience.
In Python, there are two types of code-based errors, syntax errors and exceptions.
Syntax Errors
We have already seen this error already - incorrect indentation. Syntax errors will prevent execution of the program. In this example, the
if statement is missing a colon to end the statement. As you can see Python is very helpful to point out the error:
>>> if x < 9 File "<stdin>", line 1 if x < 9 ^ SyntaxError: invalid syntax
Exceptions
Exception errors occur during program execution. Python has a number of built-in exceptions. For example:
>>> 12/0 Traceback (most recent call last): File "<stdin>", line 1, in <module> ZeroDivisionError: integer division or modulo by zero
Semantic Errors
Semantic errors are errors that happen as a result of one or more problems in logic.
These errors can be more complex, because no error is generated. The code runs but generates unexpected and/or incorrect output, or no output. A classic example of this, would be an infinite loop that most new programmers experience at least once.
(11) Python’s Power - Packages/Modules
One of the great things about Python is the plethora of available modules, both built into the Python core and third party packages/libraries - used to extend the language. These modules can be very helpful. Some of the more utilized built-in Python modules include:
- math: mathematical functions from the standard library of the C (you’ve seen this one already)
- random: a pseudo-random number generator
- datetime: used for manipulating dates and times
- re: for working with regular expressions
For example, here we
import math to use
pi,
sqrt (square root) and
pow (raising to the power):
Warning: Do not name your Python files the same as a module - like math.py or random.py. This will cause conflicts, resulting in unexpected behavior in your code. So if you are using the math module, do not name your file math.py. Make sense?
Pip
The best way to manage Python’s third party packages/modules is with pip. New coders frequently hit a wall when they are following some example code and they see the following error when they try to run the code:
ImportError: No module named MODULE_XXXX.
These modules need to be manually installed using Pip. In Python 3, pip, called pip3, is included. If you used Homebrew to install Python, pip is included as well. Starting with Python 2.7.9, pip is also included. If you are using a Python version prior to 2.7.9, follow these instructions to install pip:
- Download get-pip.py, confirm that the file was saved with a .py extension.
- Navigate to the location of the downloaded file in the Terminal or Command Prompt.
- Run:
python get-pip.py
- Read the official pip documentation for more information.
(12) Next Steps
There are plenty of online tutorials, books, and videos freely available.
My first stop was one of the most popular free choices, Learn Python the Hard Way. Zed Shaw’s tutorial is laid out in a progressive and logical exercise format. I found it very useful for learning the syntax, but I needed more.
One of the best ways of learning how to code is by building - the project driven learning approach. That’s how I came across Real Python. There are three Real Python that cost a modest fee, which are frequently updated (usually bi-monthly) to keep up with changes (free of charge).
Another place that truly helped me was MIT’s course, Introduction to Computer Science and Programming, which covers various computer science concepts along with Python. The course can be found in two locations.
- The Harvard and MIT non-profit online initiative (Edx.org) offers the course in two parts. They are challenging and provide an excellent approach to problem solving. Both parts are graded.
- The other route is from the MIT open courseware, Introduction to Computer Science and Programming MIT 6.00x. The course is not graded, but it has a very active online community that is quite helpful.
There are other online courses of course. Again, this is personal choice, so do your own research.
Another source of free learning materials comes from the PSF:
Above all, it is important that you do not fall into finding the “best” book or video search and get lost. Do some research. Ask around. But pick something and stick with it! Open your code editor and start coding! Make a commitment to yourself to complete it.
(13) Riding a Bike
Coding is like riding a bike: You can watch people to see how it is done, and sometimes you can get a push, but in the end it is a solo event. When I get stuck, or need to brush up on a new concept, the first place I go is Google. If I get an error message, typing in the exact error message, into Google, will often bring up a result in the first page that solves my problem.
- The official Python Docs - Python 2.7 or Python 3
- Tutorials Point has some very simple and easy to follow examples when I need a quick refresh.
- Jeff Knupp’s website (the author of the Idiomatic Python series of tutorials and books)
- The Real Python Blog has more specific topics and advanced subjects like Python’s Web Frameworks, Django and Flask.
- Bernd Klein’s Python Course contains excellent coverage of Python; his discussion of advanced topics is really helpful.
- Stack Overflow, the Q&A for coding, has some great explanations of Python topics. How Python can slice a string, is one truly excellent example.
If you get stuck on a problem, try these simple suggestions:
- Stop coding!
- Get out a piece of paper and map out how to solve the problem using plain words (pseudocode); use a flow chart if necessary. Refer to the example above.
- At some point you will be introduced to Python’s exception handling - the
try/exceptblock. Do not use use a
tryuntil your code is working. The
trycan suppress valuable error messages that help identify problems in code.
- If you are not getting expected output - i.e., perhaps Python is displaying a word instead of a number (incorrect data type) - add a print statement right after the variable assignment and then right before the expected output. This is an effective, quick and dirty problem solver.
- If you are still stumped, a great tool is the Python Visualizer. This tool allows you to ‘step through’ your code as it executes. The Python Visualizer has examples to help you if needed.
- One final note - and this is very important - is that a frustrated brain is not going to help. When you start to get annoyed because something is not working, take a break, clear your brain. Go for a run. Do something else. You will be amazed just how effective this can be. Often, you’ll come back with clear eyes and see a simple typo, a misspelled keyword, etc.
(14) Simple Advice for New Coders
I say this in the nicest kind of way - no one is going to spoon feed you. Coders expect other coders - yes, even beginners - to try and resolve the issue themselves. At some point we all need guidance, though.
Once you have tried and truly have hit the wall ask for help, before you smash your keyboard or other inanimate object(s). There are a number of places to get help - code forums, Facebook Groups, the IRC channel #python, to name a few. Take a minute to read any rules or guidelines for any of the groups that you use. Make it easy for others to help you by explaining the problem and what you have tried. If there is an error, include that information as well.
Have fun coding!
(15) Test your knowledge
- What does it mean that Python is a strong, dynamically typed language?
- How do you access the Python Shell?
- How do you declare’s a dictionary?
- Why should you use comments in your code?
- Test out the
help()function. What did you learn?
- Pass in
floatto the
dir()function. What did you learn?
- One primitive that we didn’t go over is
None. What does it represent?
- You can check the data type of a variable or a value by using the
type()function. Test this out using various data types and variables. What did you learn?
Open your text editor and create a new file called exercise.py. Copy and paste the following code into the file:
########################################################################## ## Modify the variables so that all of the statements evaluate to True. ## ########################################################################## var1 = var6 = var2 = var3 = var4 = var5 = ############################################ ## Don't edit anything below this comment ## ############################################ # integers print(type(var1) is int) print(type(var6) is float) print(var1 < 35) print(var1 <= var6) # strings print(type(var2) is str) print(var2[5] == 'n' and var2[0] == "p") # lists print(type(var3) is list) print(len(var3) == 5) # tuples print(type(var4) is tuple) print(var4[2] == "Hello, Python!") # dictionaries print(type(var5) is dict) print("happy" in var5) print(7 in var5.values()) print(var5.get("egg") == "salad") print(len(var5) == 3) var5["tuna"] = "fish" print(len(var5) == 3)
Following the instructions, update the code. When done, run the code from your terminal to test using the
python exercise.py command. Good luck!

Explore the tree structure of an XML document with xmllint's shell mode.
xmllint is a command-line tool available as part of libxml2 (). It is included in distributions such as Cygwin () and Red Hat Linux (). You can also download xmllib2 individually from. xmllint has an interactive shell mode that lets you traverse an XML document's tree structure as if it were a file structure, allowing you to examine any node in the tree discretely. Provided that you have an Internet connection, this shell mode will work on remote files as well as local ones. This hack will show you how it's done.
While in the working directory, we first invoke the shell on an XML document with xmllint:
xmllint --shell time.xml / >
A prompt appears (>). The location in the tree is shown to the left of the prompt (/), but with the depth of only one node. Enter the dir command to see information about the document or root node, and follow that with the base command to see the base URI of the document being explored:
/ > dir DOCUMENT version=1.0 encoding=UTF-8 URL=time.xml standalone=true / > base time.xml />
Move to a different node with cd, followed by another dir, then by a cat command:
/ > cd time/atomic atomic > dir ELEMENT atomic ATTRIBUTE signal TEXT content=true atomic > cat <atomic signal="true"/> atomic >
A dir gives you information about the node, and cat gives you the XML representation of the node. Try the validate directive:
atomic > validate validity error : no DTD found! atomic >
time.xml doesn't have a DTD associated with it, so load valid.xml (which has a document type declaration) and try validate again:
atomic > load valid.xml / > validate / >
load replaces the current document time.xml with valid.xml, so validate is successful this time (no bad news means success). Use cd to move down the tree to time, enter pwd to see the path to the current node, and then enter du to see the element names in the subtree:
/ > cd time time > pwd /time time > du time hour minute second meridiem atomic time >
Save the document in a new file with the save command, and then exit the shell with bye (exit and quit work, too):
time > save timeagain.xml time > bye
You can also invoke the shell on a remote file (follow it with base):
xmllint --shell / > base / >
You will be able to use the same commands on a remote document as you did on the local file. A list of xmllint's shell commands concludes this hack.
Following are the shell commands available in xmllint's shell mode:
Display the xml:base of the node.
Leave the shell (same as exit and quit).
Display the path to the node, if one is given, or the path to the current node.
Change the current node to the path if given and unique, but change to the document or root node if no argument is given.
Dump information about elements, attributes, namespaces, and so forth. Select the current node or node in the path, if given.
Show the structure of the subtree under the current node or the path, if given.
Leave the shell (same as bye and quit).
Show help.
Display memory usage.
Load a new document with the given name.
List contents of the path if given or the current directory.
Display the path to the current node.
Leave the shell (same as bye or exit).
Save the current document to the document name if given or to the original name.
Check the document for errors.
Write the current node to the given filename. | http://etutorials.org/XML/xml+hacks/Chapter+3.+Transforming+XML+Documents/Hack+35+Explore+a+Document+Tree+with+the+xmllint+Shell/ | CC-MAIN-2017-22 | refinedweb | 607 | 73.27 |
This article presents an overview of CRUD operations, using a single stored procedure in ASP.NET MVC of real- time projects
CRUD means create update and delete.
With ASP.NET in MVC, we can also perform CRUD operations using stored procedure.
Description
Using a single stored procedure means selecting, updating, inserting and deleting all SQL queries; we can put in one stored procedure and perform this CRUD operation by calling only this single stored procedure.
Step 1
Create MVC Application named “SatyaMvc4Crud”.
Step 2
Create a model class file called Customer.cs.
Code Ref
Code description
Here, I have created some attributes to check validation of controls, which are based on control values. For textbox name and address validation, I have put [Required(ErrorMessage = "Your Message")].
This code will be executed, if your input is empty in controls.
Now, if the user puts something but this does not satisfy the standard validation, then the code will be, as given below.
[StringLength(4, ErrorMessage = "Name should be less than or equal to four characters.")]
The user can put only four characters to control the input values.
Like this, you can check for other attributes, which are based on control validation values.
Here, I will declare 6 different entities to access the user and inputs. For every entity, I required an attribute to show the validation message failed for the end users.
e.g. [Required(ErrorMessage = "Enter Your Name")]
Like this required attribute, I used StringLength, Display, DisplayFormat, RegularExpression attributes.
We have used some attributes. For this, we have to add one namespace.
using System.ComponentModel.DataAnnotations;
In name part, I can enter up to 4 characters.
[StringLength(4, ErrorMessage = "Name should be less than or equal to four characters.")]
In address part, I can enter up to 10 characters.
[StringLength(10, ErrorMessage = "Address should be less than or equal to ten characters.")]
In MobileNo. part, I can enter only 10 digit valid phone no.
In an E-mail Id part, I can enter only a valid E-mail Id with @ symbol.
In Date Time part, I can enter only valid date, which should be less than current date.
For Custom validation of the entities, Code Ref is given below.
Here, I have used one Custom Validation class to customize your Date time validation. For this, I created one class file in Models folder named “CustomValidationAttributeDemo.cs” .
Here, I used one date time variable to access date time .
Thus, I put some code to take the user’s birth date. Birth date should always be less than today’s date.
Here, I used one class, ValidBirthDate, that is inherited from ValidationAttribute class.
Here, System.ComponentModel.DataAnnotations.dll file references for this class files.
#region Assembly System.ComponentModel.DataAnnotations.dll, v4.0.0.0 // C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\System.ComponentModel.DataAnnotations.dll #endregion
The ValidationResult override method is used to represent a container for the result of the validation request. The ValidationContext class acts as a parameter inside ValidationResult override method. It is used to describe a context in which validation check is performed.
In custom validation class, I used Student.cs for DATE TIME entity. According to this, the user input date should be less than today’s date.
Here, CustomValidationAttributeDemo is the name of the Model Class and ValidBirthDate class is the child class of ValidateAttribute base class.
Step 3
Create a table to add stored procedure to perform CRUD operation in MVC.
Table SQL Ref
Table SQL Description
Here, six columns are same as entities declared in models class “Customer.cs”.
Here “[CustomerID]” is the primary key and auto increment feature is added in these columns.
Step 4
Now, create a stored procedure to perform CRUD operation in MVC.
Stored procedure Script Ref
Stored procedure Script description
Here, five @Query parameters with different value for Insert/ Update/ Delete/ Select/Search statement.
Here (@Query = 1) means for insertion of the records.
Like this, other (@Query = 2 to 5) is assigned for other operation performances.
By using single procedure by using this individual query parameter values; we can perform different operations.
Step 5
Create a class file called DataAccessLayer.cs inside manually created folder named DataAccess.
To add connection string, add name as well as stored procedure name to perform CRUD role.
Code Ref
Here, I will show how to implement query parameter value, which is 1 to implement in this class file to perform insert operation.
In this InsertData() function, I used @Query = 1 value to perform insert operation. Here, I have added stored procedure name.
To perform update operation, I have added the code in UpdateData function.
To perform delete operation, I have added the code in DeleteData function.
To perform select list of data, I have added the code in Selectalldata list function of customer model class.
I have added one for loop to perform selection of all the data loop wise by using customer model class.
Now, I will filter the records by using customer Id values.
I have added the code given below.
Thus, I have added customer Id parameter in a function of customer model class.
Now, I have closed the connection in every functions in this class by using catch and finally block.
Step 6
Create a controller class file called CustomerController.cs.
In this controller class file, I have created one controller action method.
Here, DataAccessLayer is added as a reference to use all its methods.
The code is given below for checking model is valid or not.
Here, if the condition satisfies, then model state will be valid, else the data will not save properly.
Here, I added the show details view page name as soon as the data is inserted successfully, the page will show you the list of inserted data.
In ShowAllCustomerDetails action result method, the Selectalldata of DataAccessLayer class is used.
In Details action result method, the SelectDatabyID of DataAccessLayer class is used.
The passed parameter value with the related data will be shown in the corresponding view page.
The edit action result method has two attributes httpget and httppost.
For httpget attribute In “Edit” action result method, the “SelectDatabyID” of DataAccessLayer class is used to step update data by using this particular data.
The passed parameter value with the related data will be shown in the corresponding view page.
For httppost attribute, the edit controller action method takes customer model class object and UpdateData of DataAccessLayer class is used.
In Delete action result method, the DeleteData of DataAccessLayer class is used.
The passed parameter value with the related data will show to perform delete operation in the corresponding view page.
Step7
Now, create view cshtml file called ShowAllCustomerDetails.cshtml, InsertCustomer.cshtml.
,” Edit.cshtml”,” Details.cshtml”,” Delete.cshtml”.
Code ref. of InsertCustomer.cshtml
In this view page, I have added customer class reference or namespace.
To make validation summary active, use this code.
Now, I have added some code to make textbox and label control according to customer model class entities.
To add label control, the code is given below.
@Html.LabelFor()
To add textbox control, the code is given below.
@Html.EditorFor()
To add validation messages, as defined in customer model class and customized model validation class, the code is given below.
@Html.ValidationMessageFor()
Here, two types of buttons are used to save the data.
Here, two types of buttons are used; where one is to reset the data.
After saving data, the details view page will come with all the saved data.
Here, ShowAllCustomerDetails is the name of the controller action method as well as view name.
Here, I have added one hyperlink to redirect to other page.
Code ref. of Edit.cshtml
In this view pag,e the editor and label controls will bound existing data to update it. Hence, the data as in insert view page will load in corresponding HTML helper control and the user will update, as per requirement.
After update process completes, the view details page will come.
Here, I used multiple submit button for different actions.
Here, I have added hidden field control associate with customerid to perform an edit operation.
Code ref. of Details.cshtml
In this view page, the data inserted and updated data will show for reporting purpose.
Here, no submit button is required to take action in page event.
Afterwards, the page will redirect to view details page.
Code ref. of Delete.cshtml
Code description
In this view page, the delete confirmation text message is added in header.
In button event, JavaScript message was added and the user will decide whether it will be deleted or not.
The data is loaded and is based on the selection of customer id and data associated with the entities defined in customer model class, which will be deleted.
Here, I have added hidden field control associate with customerid to perform delete operation.
After this the page will redirect to view details page.
Code ref. of ShowAllCustomerDetails.cshtml
Code description
In this page, all the data will be visible along with EDIT/ DELETE/ DETAILS link to perform Crud operation.
The data will be shown, using “@Html.DisplayFor” html helper control in looping.
Here, I added the namespace of customer model class.
The title of the page will be written here.
To go to new customer insertion view page, the code is given below.
Here ,
Link name : "New Customer",
The method defined in customer control class file as well as data access layer class file is InsertCustomer,
Controller Name: "Customer"
Here, I am using tempdata method mechanism to transfer the data from one page to other.
To show insertion successful message, the code is given below.
To show update successful message, the code is given below.
To show delete successful message, the code is given below.
To get current data time for better visualization to the client, the code is given below.
Step 8
Add connection string in Web.config file.
Here, “mycon” is the connection string name to be mentioned in Data Access Layer class file to make connection to the database as well as make CRUD operation.
Now, put your correct connection string .
Step 9
Set start page when MVC page loads first time.
Here, I have mentioned set start page.
Here, Controller name is Customer.
Now, the view name/ controller action method is ShowAllCustomerDetails.
Step 10
You can customize the style of your own view design by using Site.css.
Here, you can add color, font size, font style and margin etc.
Step 11
Add and check reference Dll/ Assembly files to check version and other information.
In the References folder, you can check all DLL file information by right click and going to properties.
OUTPUT
The set start page URL is given below.
Load data details with CRUD functionalities
Insert page
Update page
Details page for report requirement
Delete page
For delete confirmation, it is, as shown below.
Total Operations In One Flow
Show all the data on the page is given below.
Insert some data
Update some data
Details of some data
Delete of some data
Now, the deleted data is not showing that it is empty now.
To insert new records, click the New Customer link.
Check date and time at footer of the show details view page.
Like above mentioned methods, you can implement CRU operation, using MVC in your real time scenario.

#include <gromacs/utility/stringutil.h>
Stores settings for line wrapping.
Methods in this class do not throw.
Initializes default wrapper settings.
Default settings are:
Returns the indentation set with setFirstLineIndent().
If setFirstLineIndent() has not been called or has been called with -1, indent() is returned.
Sets a continuation marker for wrapped lines.
If set to non-zero character code, this character is added at the end of each line where a line break is added by TextLineWrapper (but not after lines produced by explicit line breaks). The default (
'\0') is to not add continuation markers.
Note that currently, the continuation char may cause the output line length to exceed the value set with setLineLength() by at most two characters.
Sets the indentation for first output line after a line break.
If this method is not called, or called with
indent equal to -1, the value set with setIndent() is used.
Sets the indentation for output lines.
If this method is not called, the wrapper does not add indentation.
Sets whether final spaces in input should be kept.
This means that wrapping a string that ends in spaces also keeps those spaces in the output. This allows using the wrapper for partial lines where the initial part of the line may end in a space. By default, all trailing whitespace is removed. Note that this option does not affect spaces before an explicit newline: those are always removed.
Sets the maximum length for output lines.
If this method is not called, or is called with zero
length, the wrapper has no maximum length (only wraps at explicit line breaks). | https://manual.gromacs.org/current/doxygen/html-full/classgmx_1_1TextLineWrapperSettings.xhtml | CC-MAIN-2021-39 | refinedweb | 268 | 75 |
Shopify / Liquid specific loop index within loop
In Shopify I am trying to cycle through some metafields that contain feature titles. Then I need to cycle through some other metafields and get the feature description based on the current loop index.
This code works just fine for me, but it is very inelegant and I'm sure there is a much better way to achieve the same result!
{% for field in product.metafields.feature_title %} <h4>{{ field | last }}</h4> {% assign i = forloop.index %} {% if forloop.index == 1 %} <p>{{ product.metafields.feature_description.001 }}</p> {% endif %} {% if forloop.index == 2 %} <p>{{ product.metafields.feature_description.002 }}</p> {% endif %} {% if forloop.index == 3 %} <p>{{ product.metafields.feature_description.003 }}</p> {% endif %} {% if forloop.index == 4 %} <p>{{ product.metafields.feature_description.004 }}</p> {% endif %} {% if forloop.index == 5 %} <p>{{ product.metafields.feature_description.005 }}</p> {% endif %} {% endfor %}
Additionally there is a flaw that this is limited to 5, or whoever many if statements creates.
Cheers,
DB
Answer
Solution:
not tested but something like this should work:
{% for field in product.metafields.feature_title %} <h4>{{ field | last }}</h4> {% capture idx %}00{{forloop.index}}{% endcapture %} {% assign key = idx | slice: -3, 3 %} <p>{{ product.metafields.feature_description[key]}}</p> {%. | https://e1commerce.com/items/shopify-liquid-specific-loop-index-within-loop | CC-MAIN-2022-40 | refinedweb | 195 | 54.29 |

Log:
DERBY-675: The "readLine" method in ODBCMetadataGenerator.java was treating
single backslashes as "end-of-line" markers and hence was not recognizing
escaped sequences like "\n". It turns out that the check for backslashes in
that method is unnecessary, so this patch removes it. I ran the metadata.java
and odbc_metadata.java tests with this patch and they ran okay, so I think it
should be safe. I still want to run some more tests tonight, just to be sure,
but I thought I'd post the patch now since it is affecting another developer's
current work (Mamta's).

I had a great time yesterday at Roanoke Code Camp! Many thanks to American National University for the venue, the code camp staff and volunteers, the other speakers, and of course the attendees who made my sessions interactive. I learned a lot yesterday and it was a good time all around.
I attended sessions on Apache Cassandra by Dr. Dave King (@tildedave), Angular JS by Kevin Israel (@kevadev), and JavaScript for Object-Oriented Programmers by Joel Cochran (@joelcochran). I regret I was unable to attend all the sessions.
I also had the opportunity to present. I spoke on Redis and got some people excited about graph databases by talking about Neo4j. You can find my slides and other materials at the following links:
If you have any trouble getting any of the materials just respond to this post or tweet me @codesailor and I will make sure you get the information you need.
Recently I started working with Neo4j in C#. I am using the Neo4jClient and decided to write a wrapper for it using Generics. In this blog post I'll show how I did it. As always, your feedback is appreciated.
The first is the CRUD operations provider. CRUD stands for Create, Retrieve, Update, Delete in case you don't know. The CRUD provider is quite simple.
But before we jump into that, we need to make some concessions. We must have a common base type with a common property in order to find the node on successive calls. So I created a base class with a single property, “Id”, as an int. You can choose any property or properties you like but for simplicity I chose a small footprint. Here is my base class:
public abstract class Neo4jBase
{
public int Id { get; set; }
}
(I don’t know why the “I” is uppercase. I guess I got a little keyboard crazy.)
With that in place, we can build our CRUD data provider. Remember, you must be using the Neo4jClient library. Here is my generic provider:
using Neo4jClient;
public class Neo4jDataProvider<T> where T : Neo4jBase
{
IGraphClient _client = null;
public Neo4jDataProvider (IGraphClient client)
{
_client = client;
}
public T Create(T record)
if (_client != null)
{
var inputString = string.Format("({0}:{1}", typeof(T).Name.ToLower(), typeof(T).Name);
inputString += " { newRecord })";
_client.Cypher
.Create(inputString)
.WithParam("newRecord", record)
.ExecuteWithoutResults();
}
return record;
public T Retrieve(int id)
T result = null;
var inputString = string.Format("({0}:{1})", "record", typeof(T).Name);
var query = _client.Cypher
.Match(inputString)
.Where((T record) => record.Id == id)
.Return(record => record.As<T>());
result = query.Results.FirstOrDefault();
return result;
public T Update(T entry)
_client.Cypher
.Match(inputString)
.Where((T record) => record.Id == entry.Id)
.Set("record = {updatedRecord}")
.WithParam("updatedRecord", entry)
}
return entry;
public void Delete(int id)
.Where((T record) => record.Id == id)
.Delete("record")
}
}
}
So what’s going here? First it is a generic class of type T where T is a Neo4jBase object. The reason is the Id property. That property allows us to find and deal with nodes individually in an easy and familiar fashion. Notice that the constructor takes an IGraphClient object. It is expected the IGraphClient is instantiated and connected to a database.
The next point to note is the use of the type of T as the label. For those of you new to graph databases, the “label” is the “type” of the node in the database. For example, labels may be “Person”, “Movie”, “Book”, etc. So in each method, the name of the type of T is used as the label. You will also see the word “record” scattered throughout the code. This is used as a variable name.
An interesting behavior is that the .WHERE methods seem to break if the variable name in the .MATCH methods is not the same name as the name of the variable in the lambda expression.
What about Relationships?
Remember that relationships are first-class citizens in graph databases, just like nodes. However, since relationships involve nodes of various types I decided to create a separate class for handling them. The class is still a generic class but instead uses two different types, TLEFT and TRIGHT.
A caveat: 1) The relationships data provider only handles unidirectional relationships (always left-to-right); Here is the relationship data provider:
public class Neo4jDataProviderRelationships<TLeft, TRight> where TLeft : Neo4jBase where TRight : Neo4jBase
{
public Neo4jDataProviderRelationships(IGraphClient client)
public void Associate(TLeft left, string relationshipName, TRight right)
var inputStringLeft = string.Format("({0}:{1})", "tleft", typeof(TLeft).Name);
var inputStringRight = string.Format("({0}:{1})", "tright", typeof(TRight).Name);
.Match(inputStringLeft, inputStringRight)
.Where((TLeft tleft) => tleft.Id == left.Id)
.AndWhere((TRight tright) => tright.Id == right.Id)
.Create("tleft-[:" + relationshipName + "]->tright")
public void Dissociate(TLeft left, string relationshipName, TRight right)
.Match(inputStringLeft + "-[:" + relationshipName + "]->" + inputStringRight)
.Delete(relationshipName)
Notice that like the CRUD data provider, an IGraphClient is expected by the constructor. There are two methods for associating and dissociating nodes.
Usage
So how are these classes used? Well, suppose you have a class, Person, and a class, Movie as follows (borrowed from the demo database that ships with Neo4j):
public class Movie : Neo4jBase
{
public string title { get; set; }
public string released { get; set; }
public string tagline { get; set; }
}
public class Person : Neo4jBase
{
public string name { get; set; }
public string born { get; set; }
}
Now suppose you want to create a Person and a Movie and relate them. Specifically, let’s create William Shatner, and Airplane II, and relate them. First, create the nodes:
Neo4jDataProvider<Person> personDataProvider = new Neo4jDataProvider<Person>(client);
Person person = new Person { Id = 1, born = "1966", name = "William Shatner" };
personDataProvider.Create(person);
Neo4jDataProvider<Movie> movieDataProvider = new Neo4jDataProvider<Movie>(client);
var movie = new Movie { Id = 1, released = "1982", tagline = "The Sequel", title = "Airplane II" };
movieDataProvider.Create(movie);
That will create the two nodes. Let’s relate them:
Neo4jDataProviderRelationships<Person, Movie> relDataProvider = new Neo4jDataProviderRelationships<Person, Movie>(client);
relDataProvider.Associate(person, "ACTED_IN", movie);
And that’s it!
What’s the catch?
There are a number of catches including:
I’m sure there are more catches. As an apology, I am just getting started. I hope to extend these classes with more robust operations. Your feedback is appreciated. If someone has already done this (or something similar) I’d love to know about it.
Recently.
The team spent much of the week working through this issues related to Chrome running on Windows 8 consuming cross-origin resources using Web API. We thought it was resolved on day 2 but it resurfaced the next day. We definitely resolved it today though. I believe I do not fully understand the situation but I am going to explain what I know in an effort to help you avoid and/or resolve a similar issue.
My Lotic Factor colleagues Joel Cochran and Chris Atienza suffered with me and Joel wrote an excellent, complementary blog post to this post.
We referenced many sources during our trial-and-error troubleshooting. These are the links we reference in order of applicability to the solution:
Zoiner Tejada
JavaScript and other material from ->
WebDAV
Where I learned about “Accept” –>?

Tells about NOT using ‘*’ –>
Carlos Figueira
Sample back-end code (newer) –>
(older version) –>
As a measure of protection, Web designers (W3C) and implementers (Google, Microsoft, Mozilla) made it so that a request, especially a JSON request (but really any URL), sent from one domain to another will only work if the requestee “knows” about the requester and allows requests from it. So, for example, if you write a ASP.NET MVC Web API service and try to consume it from multiple apps, the browsers used may (will?) indicate that you are not allowed by showing an “Access-Control-Allow-Origin” error indicating the requester is not allowed to make requests.
Internet Explorer (big surprise) is the odd-hair-colored step-child in this mix. It seems that running locally at least IE allows this for development purposes. Chrome and Firefox do not. In fact, Chrome is quite restrictive. Notice the images below. IE shows data (a tabular view with one row for each day of a week) while Chrome does not (trust me, neither does Firefox). Further, the Chrome developer console shows an XmlHttpRequest (XHR) error.
Screen captures from IE (left) and Chrome (right). Note that Chrome does not display data and the console shows an XHR error.
The Web browser submits these requests and processes the responses and each browser is different. Okay, so, IE is probably the only one that’s truly different. However, Chrome has a specific process of performing a “pre-flight” check to make sure the service can respond to an “Access-Control-Allow-Origin” or Cross-Origin Resource Sharing (CORS) request. So basically, the sequence is, if I understand correctly:
1)Page Loads –> 2)JavaScript Request Processed by Browser –> 3)Browsers Prepares to Submit Request –> 4)[Chrome] Browser Submits Pre-Flight Request –> 5)Server Responds with HTTP 200 –> 6)Browser Submits Request –> 7)Server Responds with Data –> 8)Page Shows Data
This situation occurs for both GET and POST methods. Typically, GET methods are called with query string parameters so there is no data posted. Instead, the requesting domain needs to be permitted to request data but generally nothing more is required. POSTs on the other hand send form data. Therefore, more configuration is required (you’ll see the configuration below). AJAX requests are not friendly with this (POSTs) either because they don’t post in a form.
The team went through many iterations of self-hair removal and we think we finally have a working solution. The trial-and-error approach eventually worked and we referenced many sources for the information. I indicate those references above. There are basically three (3) tasks needed to make this work.
Assumptions: You are using Visual Studio, Web API, JavaScript, and have Cross-Origin Resource Sharing, and several browsers.
1. Configure the client
Joel Cochran centralized our “cors-oriented” JavaScript (from here). There are two calls including one for GET and one for POST
);
The GET & PUT CORS JavaScript functions (credit to Zoiner Tejada, Joel Cochran)
Now you need to call these functions to get and post your data (instead of, say, using $.Ajax). Here is a GET example:
corsAjax.get(url, function(data) { if (data !== null && data.length !== undefined) { // do something with data } });
corsAjax.get(url, function(data) { if (data !== null && data.length !== undefined) { // do something with data } });
And here is a POST example:
corsAjax.post(url, item);
corsAjax.post(url, item);
Simple…except…you’re not done yet.
2. Change Web API Controllers to Allow CORS
There are actually two steps here. Do you remember above when we mentioned the “pre-flight” check? Chrome actually asks the server if it is allowed to ask it for cross-origin resource sharing access. So you need to let the server know it’s okay. This is a two-part activity. a) Add the appropriate response header Access-Control-Allow-Origin, and b) permit the API functions to respond to various methods including GET, POST, and OPTIONS. OPTIONS is the method that Chrome and other browsers use to ask the server if it can ask about permissions. Here is an example of a Web API controller thus decorated:
NOTE: You’ll see a lot of references to using “*” in the header value. For security reasons, Chrome does NOT recognize this is valid.
. } }
Please note a few specific additions here:
* The header attributes at the class level are required. Note all of those methods and headers need to be specified but we find it works this way so we aren’t touching it.
* Web API will actually deserialize the posted data into the object parameter of the called method on occasion but so far we don’t know why it does and doesn’t.
* [HttpOptions] is, again, required for the pre-flight check.
* The “Access-Control-Allow-Origin” response header should NOT NOT NOT contain an ‘*’.
3. Headers and Methods and Such
We had most of this code in place but found that Chrome and Firefox still did not render the data. Interestingly enough, Fiddler showed that the GET calls succeeded and the JSON data is returned properly. We learned that among the headers set at the class level, we needed to add “ACCEPT”. Note that I accidentally added it to methods and to headers. Adding it to methods worked but I don’t know why. We added it to headers also for good measure.
[HttpHeader("Access-Control-Allow-Methods", "ACCEPT, PROPFIND, PROPPA... [HttpHeader("Access-Control-Allow-Headers", "Accept, Overwrite, Destin...
[HttpHeader("Access-Control-Allow-Methods", "ACCEPT, PROPFIND, PROPPA... [HttpHeader("Access-Control-Allow-Headers", "Accept, Overwrite, Destin...
That should do it. If it doesn’t let us know. What to do next?
* Don’t hardcode the allowed domains. Note that port numbers and other domain name specifics will cause problems and must be specified. If this changes do you really want to deploy updated software? Consider Miguel Figueira’s approach in the following link to writing a custom HttpHeaderAttribute class that allows you to specify the domain names and then you can do it dynamically. There are, of course, other ways to do it dynamically but this is a clean approach.

Lindsay is an American anti-war activist and presidential nominee of the Party for Socialism and Liberation despite being ineligible to become president due to her age, under Article II, Section 1, Clause 5 of the U.S. Constitution; she would need to be at least 35 in order to take office.
Lindsay was born in Virginia and grew up in Philadelphia, Pennsylvania. She became an activist as a middle school student with the Philadelphia Student Union, a non-profit organization of students demanding a high quality education. She was a high school senior in Washington D.C. during the September 11 attacks. Soon thereafter she became active with the ANSWER coalition (Act Now to Stop War and End Racism). On September 24, 2001, Lindsay spoke at ANSWER's first press conference as a high school student. In 2002, she traveled to Cuba with Pastors for Peace. She attended Howard University and continued as a leader with the ANSWER coalition, including as a lead organizer of the January 2003 protest against the upcoming Iraq War. She was recognized by The Washington Post in March 2003 for her anti-war activism in a piece entitled "Student Leader Sees Through Bush Propaganda". In October 2003, Lindsay said of the Iraq War, "The US government has no right to try and recolonize Iraq".
The Party for Socialism and Liberation (PSL) is a Marxist-Leninist political party in the United States. It was created as the result of a split within the ranks of Workers World Party (WWP). The San Francisco branch and several other members left WWP in 2004, announcing that "the Workers World Party leadership is no longer capable of fulfilling that mission [of building socialism]". The PSL has since established two national offices in Washington, D.C. and in San Francisco alongside 23 local branches across the country.
The PSL sees as its main goal the formation of a revolutionary workers' party, based upon the ideology of Marxism-Leninism. This party would lead a revolution and pave the way towards socialism. Under socialism a new government of working people would be formed.
Historically, the PSL is generally positive on the former Soviet Union, describing the October Revolution as "the single biggest event that shaped global politics in the 20th century". The PSL acknowledges that the New Economic Policy of Vladimir Lenin led "to a re-polarization of social classes, especially in the countryside". The PSL blames the reforms initiated by Mikhail Gorbachev for the fall of the Soviet Union
The PSL is a member of the steering committee of the Act Now to Stop War and End Racism Coalition (A.N.S.W.E.R.). As one of the most active members of the coalition, PSL has gained notice for successfully forging ties with Arab and Muslim American groups such as the Muslim American Society, Al-Awda and the American-Arab Anti-Discrimination Committee.

Python packages - the simple way.
Project description
Easy Package - for Python
Python packages - the simple way.
Background
Had to code Python so ended up abstracting out these Python package related utilities to be able to deal with Python packages which is in a sad state in comparison to most other language environments.
Features
Easy package (system) load paths - because package imports and load paths in Python makes adults cry.
Easy package tag/release - because package tag/release management should not be done by hand, fallback on conventions.
Install
Install using pip:
pip install easypackage
Usage
How to to make use of
easypackage in various ways:
Required
Create a
package.json in package root folder (e.g.
mypackage) - see Node.js specification, in lack of such for Python.
Easy package load paths
In any package source file:
# e.g. `~/dev/projects/mypackage/foo/foo.py` def hello: print('hello!')
In any other package source file:
# e.g. `~/dev/projects/mypackage/bar/bar.py` from easypackage import syspath as easysyspath # add `~/dev/projects/mypackage` to Python system path unless already added easysyspath.syspath() from mypackage.utils.foo import foo foo.hello()
And so on.
Easy package tag/release (WIP/TBA)
In file
release.py in package project root:
from easypackage import release as easyrelease easyrelease.release()
To tag/release a new version to Git, simply add/update a valid semver version tag in
package.json - according to Node.js specification - and then run
python release.py.
Currently not submitted to any Python package register, but will probably be added soon.
License
Released under the MIT license.

Django Blog Tutorial - the Next Generation - Part 2
Welcome back! In this lesson, we’ll use Twitter Bootstrap to make our blog look nicer, and we’ll implement individual pages for each post.
Now, before we get started, don’t forget to switch into your virtualenv. From within the directory for the project, run the following command:
$ source venv/bin/activate
If you haven’t used Bootstrap before, you’re in for a treat. With Bootstrap, it’s easy to make a good-looking website quickly that’s responsive and mobile-friendly. We’ll also use HTML5 Boilerplate to get a basic HTML template in place.
Now, to install these easily, we’ll use Bower, which requires Node.js. Install Node.js first. On most Linux distros, you’ll also need to set
NODE_PATH, which can be done by pasting the following into your
.bashrc:
NODE_PATH="/usr/local/lib/node_modules"
With that done, run the following command to install Bower:
$ sudo npm install -g bower
Next we need to create a Bower config. First, create the folder
blogengine/static. Then create a new file called
.bowerrc and paste in the following content:
This tells Bower where it should put downloaded libraries. Next, run the following command to gener Bower:
$ bower init
Answer all the questions it asks you - for those with defaults, these should be fine, and everything else should be easy enough. Next, run the following command to install Bootstrap and HTML5 Boilerplate:
$ bower install bootstrap html5-boilerplate --save
Note that as jQuery is a dependency of Bootstrap, it will also be installed automatically. Now, we need to keep our Bower-installed files out of version control - the
bower.json file keeps track of them for us. So add the following to your .gitignore file:
blogengine/static/bower_components/
All done? Let’s commit our changes:
Now, let’s make our template nicer. Django’s templating system is very powerful and lets one template inherit from another. We’re going to create a base template, using HTML5 Boilerplate as a starting point, that all of our web-facing pages will use. First, create a directory to hold the base template:
$ mkdir templates/blogengine/includes
Then copy the
index.html file from HTML5 Boilerplate to this directory as
base.html:
$ cp blogengine/static/bower_components/html5-boilerplate/index.html templates/blogengine/includes/base.html
Now amend this file to look like this:
Note the following:
- We need to use
{% load staticfiles %}to be able to load any static files.
- We use the
{% static %}template tag to load static files such as CSS and HTML
- We define blocks called
titleand
content. Any template that extends this one can override whatever is inside this template.
Please note that HTML5 Boilerplate may conceivable change in future, so bear in mind that all you really need to do is load the staticfiles app, use the
static tag for any static files that need to be loaded, and define the blocks in the appropriate places.
Next, let’s amend our existing template to inherit from this one:
Now fire up the server with
python manage.py runserver and check everything is working OK. You should see that your new base template is now in use and the CSS and JS files are being loaded correctly. Let’s commit again:
Now, let’s use Bootstrap to style our blog a little. First we’ll add a navigation bar at the top of our blog. Edit the base template as follows:
Note the footer copyright section. Here we output the current year using
now. Also note the addition of the header block. This will let us override the page header if necessary.
We’ll also wrap the posts in a div:
Let’s commit our changes:
Formatting our content
As it stands right now, we can’t do much to format our posts. It is possible to include HTML in our posts with Django, but by default it will strip it out. Also, we don’t want users to have to write HTML manually - we want to make our blog user friendly!
There are two possible approaches. One is to embed a rich text editor like TinyMCE in the admin and use that for editing the files, but I’ve found things like that to be cumbersome. The alternative is to use some other form of lightweight markup, and that’s the approach we’ll take here. We’re going to use Markdown for editing our posts.
Django has actually dropped support for Markdown, but it’s not hard to implement your own version. First, install Markdown and add it to your
requirements.txt:
Now, we shouldn’t write any production code before writing a test, so let’s amend our existing post test to check to see that Markdown is working as expected:
You’ll also need to add the following at the top:
import markdown
What we do here is we convert our post text to include a link using Markdown. We also need to render that post in markdown within the test so that what we have in the test matches what will be produced - otherwise our test will be broken. We also check that the link is marked up correctly.
Save the file and run the tests - they should fail. Now, create the following directory and file:
Note that the
__init__.py file is meant to be blank.
Then create the following file and edit it to look like this:
Then just amend the post list template to use it:
It’s that easy to use a custom markup system with your blog!
Let’s commit the changes:
Pagination
As at right now, all of our posts are displayed on the index page. We want to fix that by implementing pagination. Fortunately, that’s very easy for us because we’re using Django’s generic views. Go into
blogengine/urls.py and amend it as follows:
That will automatically paginate our posts by 5 - feel free to change the value of
paginate_by if you wish. However, we need to place the links in our template as well:
Try adding a few more blog posts, and you’ll see the pagination links. But give them a try, and they won’t work. Why not? Well, as it turns out there was a bug in the project-wide
urls.py file (my bad!). Let’s fix that:
If you try again, you’ll see that the
blogengine app now happily deals with the paginated posts. Let’s commit our changes:
Viewing individual posts
As our last task for today, we’ll implement individual pages for each post. We want each post to have a nice, friendly URL that is as human-readable as possible, and also includes the date the post was created.
First of all, we’ll implement our test for it, however:
Add this method to the
PostViewTest class, after
test_index. It’s very similar to
test_index, since it’s testing much the same content. However, not that we fetch the post-specific URL using the method
get_absolute_url, and we then fetch that page.
Now, if you run the test, it will fail because
get_absolute_url isn’t implemented. It’s often a good idea to have a
get_absolute_url method for your models, which defines a single URL scheme for that type of object. So let’s create one. However, to implement our URL scheme we need to make some changes. Right now we have the date, but we don’t have a text string we can use, known in Django as a slug. So we’ll add a slug field, which will be prepopulated based on the post title. Edit your model as follows:
Here we’ve added a slug field to the model, as well as implementing our
get_absolute_url method. Note we’ve limited the date to year and month, but you can include days if you wish.
While we’re in here, we’ve also implemented the
__unicode__ method. Essentially, this sets how Django describes the object in the admin - in this case, the post title is a logical way of describing that
Post object, so it returns the post title.
We’ve also added the class Meta, with the ordering field. This tells Django that by default any list of posts should return them ordered by
pub_date in reverse - in other words, latest first.
To have the slug filled in automatically, we need to customise the admin interface a little as well:
Now, I recommend at this stage going into the admin and deleting all of your posts, because otherwise you’ll have problems in migrating them. The issue is that each slug is compulsory and must be unique, and it’s not practical to use South to automatically generate new slugs from the title on the fly, so by deleting them at this stage you’ll avoid problems. Once that’s done, run this command:
$ python manage.py schemamigration --auto blogengine
You’ll be prompted to specify a one-off default value - enter any string you like, such as “blah”. Then run the migration:
$ python manage.py migrate
Let’s run our tests now:
Whoops! Our tests are broken, because the slug field isn’t being filled in. If you take a look at the page for adding a post, you’ll notice that the slug is filled in using JavaScript, so our test fails because the test client doesn’t interpret JavaScript. So in the tests we have to fill in the slug field manually.
Also, for the unit tests, the slug attribute isn’t being created at all, so it can’t be saved. Let’s remedy that. First, edit the
test_create_post method of
PostTest:
Next, let’s amend
AdminTest:
And
PostViewTest:
What we’re doing here is that every time we create a Post object programmatically, we add the
post.slug atttribute to it. Also, when submitting a post via the admin, we pass the
slug parameter via HTTP POST, thus emulating how a form would submit this data.
If you run the tests again, you’ll see that
test_post_page still fails. This is because we haven’t yet up the URLs, templates and views to do so. Let’s fix that. We’ll use another generic view, called a DetailView, to display the posts. Amend
blogengine/urls.py as follows:
Running our tests again will still fail, but now because the template
post_detail.html has not been found. So let’s create it:
If you run your tests again, they should now pass. However, we still need to provide a hyperlink from each post in the index to the post page, so let’s do that:
And that’s all for today! We now have individual post pages, we’ve styled our blog a bit, and we’ve implemented Markdown support. All that remains is to commit our changes:
As before, I’ve tagged the final commit with ‘lesson-2’, so if you’re following along, you can switch to this point with
git checkout lesson-2.
Next time we’ll add support for flat pages and multiple authors, as well as adding support for comments via a third-party commenting system. | https://matthewdaly.co.uk/blog/2014/01/02/django-blog-tutorial-the-next-generation-part-2/ | CC-MAIN-2019-51 | refinedweb | 1,881 | 71.44 |

Deployment Platforms
Draco plugs into the Apache/mod_python combination. Both Apache 1.3 and Apache 2.0 are supported. For serious use, a relational database must be installed. Currently, the popular MySQL and PostgreSQL database systems are supported.
Suitability
Development Interfaces
No special development environment is available. Draco applications can be made just like a regular Python application using a text editor.
Environment Access
Most of the standard CGI environment is available as properties or methods of a collection of global Python objects.
Session, Identification and Authentication
Draco has an integrated and automatic session management mechanism. Both cookie and url tagging methods are supported. Sessions can be logged in, made persistent and optionally made secure by using SSL. Authentication and authorization have to be performed by the application.
Persistence Support
Draco make use of the namespace concept. A namespace is a place where you can store (almost) arbitrary Python variables using the Python dictionary API (ns['varname'] etc.). There are different namespaces, some of which are persistent. These include the session, user, application and server namespace.
Technically, persistence is implemented by a relational database backend.
Presentation Support
Process Logic versus Markup Logic
In Draco program logic is conceptually separated into process and markup logic. The process logic is the logic that processes a request and performs the desired action. The markup logic is the logic that formats the results of the process logic in the html.
Handlers and Templates
Draco makes use of handlers and templates. The process logic is put in a handler. This handler processes the client's request and performs the requested operations. The result of these operations is put in a special namespace called the interface.
The template is template as exist in many web frameworks, namely an html file with embedded code blocks. The only thing this code should do is format the results from the interface namespace into the html. All variables from the interface namespace are directly available to this code as global variables.

How do I induce the Mac graphical login from SSH? Is there a way to make the loginwindow process start a user session by running a command when remotely logged in via SSH as an admin on Mac OS X?
loginwindow.
Not knowing the password makes things complicated, but maybe the solution is: is it possible to temporarily blank out a user's password? (And afterwards reset it to whatever it was before.)
As a start:
First, get the login window to display. Just log out the current user, use fast user switching, or use SSH:
cd "/System/Library/CoreServices/Menu Extras/User.menu/Contents/Resources/"
sudo ./CGSession -suspend
Or, to switch to a specific user right away, which will probably show the login window (this suddenly no longer works on my 10.5 Leopard):
sudo ./CGSession -switchToUserID 501
What's shown now depends a bit on the System Preferences, but let's assume it's the users' icons and their names. To activate a name we'd have to type the first letters. Then, after Return, the password prompt shows. Alternatively one can select any name (like by pressing Arrow Down) and then press Option-Return to be prompted for both any username and its password. I don't know how one can tell which screen is shown, but let's save that for later...
So, to select the first (random) user name and press Option-Return, type a specific user name, hit Return, and type the password:
sudo osascript -e 'tell app "System Events"
key code 125
keystroke return using option down
keystroke "the username"
delay 1.0
keystroke return
delay 1.0
keystroke "the password"
delay 1.0
keystroke return
end tell'
The above shows some error, which as far as I can tell does not limit the usage:
osascript[285] : 3891612: (connectAndCheck) Untrusted apps are not
allowed to connect to or launch Window Server before login.
_RegisterApplication(), FAILED TO establish the default connection to
the WindowServer, _CGSDefaultConnection() is NULL.
Alternatively, use the language specific script from "Script the Login window through Apple Remote Desktop" (maybe one day the comments at that site will show a better solution):
tell process "SecurityAgent"
set value of text field 1 of group 1 of window 1 to "the username"
set value of text field 2 of group 1 of window 1 to "the password"
end tell
click button "Log In" of window 1 of application process "SecurityAgent"
But the main problem is: this still needs the password. However: obviously no password is needed when a user has a blank password. In fact, for blank passwords just clicking a user's icon is all that's needed. So, if sending keystrokes using AppleScript is acceptable, then maybe "all" that's left to figure out:
Is it possible to temporarily blank out a user's password, to allow for starting (or resuming) the session without knowing that password...?
Can one make the AppleScript error-proof? Like:
stat -f%Su /dev/console
root
(A note for testing: when using Screen Sharing it seems that setting the preference When controlling computers: Encrypt passwords and keystrokes only also retains the connection when the login window is shown, or after a user has successfully logged in. When using Encrypt all network data then my Mac needs to re-establish the Screen Sharing connection each time a login is shown or a user is switched.)
sudo osascript -e 'tell app "System Events" to keystroke "password" & return'
su
I've been investigating this recently.
Put this in your app's PAM stack, or test with sshd:
session required pam_launchd.so launchd_session_type=Aqua
That goes a long way towards getting you a graphical session which is pretty close to a switched-out user session. In particular, it's in the right bootstrap namespace and has the correct bootstrap ports (I think). You can check the source for what pam_launchd does; it's using some reasonable-looking private library (vproc_priv.h functions in libvprop) to call the Mach routines for setting up the ports and namespace. It matches with all the (limited) docs Apple provides for the Mach-derived syscalls.
Next, you need to set your audit user-id to the that of the user with the BSM API, or the loginwindow won't talk to you on Lion.
The session looks very close to a switched-out session now if you check "launchctl blist", and some processes and services come to life nicely (like the pasteboard, and so on). In fact, everything except Finder and loginwindow is running. Until loginwindow runs though, you can't launch a graphical application, and the per-session loginwindow process is always spawned as a direct child of the global one. How does one poke the loginwindow process to launch a new loginwindow in the fresh session? I can't find a way to get the last piece in place!
Any help completing this answer gratefully received.
running the command with sudo allows you to set the script to unreadable by standard users. It's not perfect, but if your admin user is already compromised, the game is over anyway!
chmod u-r scriptname
my script looks like this, it works remotely when one user is already running, to switch to a second user via SSH (tested on Snow Leopard 10.6.3):
#!/bin/bash
#go to login window
/System/Library/CoreServices/Menu\ Extras/User.menu/Contents/Resources/CGSession -switchToUserID 503
osascript -e 'tell app "System Events"
keystroke "password"
delay 1.0
keystroke return
end tell'
exit

It was easier to implement with the csproj file in the same directory as the
source files, as this is the typical VS configuration. One problem that I
encountered when I bumped the cproj file up to a higher level than the
source files was that newly created files had the incorrect namespace (
src.main.csharp....). Of course, there are other problems. Technically, from
VS perspective, the test and main are different projects, if their project
file were in the same directory, they would end up each
generating properties/files over each other.

1. Re: Using custom fonts on MenuBar Menu and/or MenuItemjsmith Mar 13, 2012 7:54 PM (in response to 921851)Although I've used custom fonts for JavaFX 1.3, I've never been able to get them to work for JavaFX 2.x.1 person found this helpful
Example 9 here talks about how to use custom fonts with JavaFX 2.x, but the example does not work for me (JavaFX 2.1-b16, WinXPsp3, JDK7u4ea) (). Perhaps I am doing something wrong, but not really sure what it is. Also I don't know how to use custom fonts in conjunction with css. So if anybody can get either of these things working, it might be useful to post how it was done.
Here is a sample code which demonstrates changing the font for the menu and the menuitem to a monospaced (e.g. Courier) font.
CSS used here:
import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.*; import javafx.scene.layout.VBox; import javafx.scene.paint.Color; import javafx.scene.text.Font; import javafx.stage.Stage; public class MenuFont extends Application { public static void main(String[] args) { launch(args); } @Override public void start(Stage stage) { final Menu fileMenu = new Menu("File"); fileMenu.getItems().add(new MenuItem("Open")); MenuBar menuBar = new MenuBar(); menuBar.getMenus().add(fileMenu); Font font = Font.loadFont(MenuFont.class.getResource("TRON.TTF").toExternalForm(), 120); Label label = new Label("TRON"); // label.setFont(font); // if this line is not commented out and the font is set, then no label is actually displayed... VBox layout = new VBox(10); layout.getChildren().addAll(menuBar, label); Scene scene = new Scene(layout, 200, 200, Color.ANTIQUEWHITE); stage.setScene(scene); stage.show(); scene.getStylesheets().add(MenuFont.class.getResource("menufont.css").toExternalForm()); } }
TRON font used is this one:
.menu-bar .label { -fx-font-family: monospace; -fx-font-size: 20; -fx-text-fill: red; } .menu-item .label { -fx-font-family: monospace; -fx-font-size: 20; -fx-text-fill: green; }
2. Re: Using custom fonts on MenuBar Menu and/or MenuItem921851 Mar 13, 2012 9:06 PM (in response to jsmith)Yours is a easy one. Use Text instead of Label.

3. Re: Using custom fonts on MenuBar Menu and/or MenuItemjsmith Mar 13, 2012 10:44 PM (in response to 921851)
Yours is a easy one. Use Text instead of Label.Thanks for the info - this was almost correct.
Setting the font on the label actually worked, but what happened was that the the custom font I created set the font size to 120, which is huge for the TRON font. This meant that the Scene was sized too small to display the Label and the label implementation converted the text to just ellipses . . ., but even the ellipses could not be seen because they were too large to be displayed on the small Scene I created. If I made the Scene larger, it displayed just fine. It seems that if you just remove the sizing on the Scene it does not work either as the font stuff does not compute the correct layout area for the custom font label and the Scene ends up too small, so you need to manually set it to the right size.
Also, as the forum post you linked hints, if you do set any styling in your program for the label which has the custom font displayed (e.g. try to change the font size via label.setStyle("-fx-font-size: 10;"), the font just reverts back to a standard font - so I guess you want to avoid that for now. What I did instead to get multiple size fonts is just make multiple calls to Font.loadFont(fontName, size).
Once I worked out how to get a custom font displayed in a label, this meant that I could perform css lookups on the scene at run-time to set the custom font for the menu items.
An example which demonstrates this is here:
The runtime lookups rely on a deprecated impl_ call to find the popped up menu items, Stage.impl_getWindows().
A css based lookup or setting the custom font from a css stylesheet would be better, but I don't know how to accomplish either.
Anyway, hope the above gives you enough information to accomplish what you want.
4. Re: Using custom fonts on MenuBar Menu and/or MenuItem921851 Mar 14, 2012 12:18 PM (in response to jsmith)Man, you won't believe me. But I finally made it and it's pretty simple!
In my Application, before call any other window, I make a call to load the font:
and then, at the css file:
javafx.scene.text.Font baumansFont = javafx.scene.text.Font.loadFont(getClass().getResourceAsStream("/fonts/Baumans-Regular.ttf"), 10);
And that's it! By the way, the approach you've shown works too, but I found too much processor intensive (n² complexity) just to use a custom font in a menu. Thanks for all the help. By the way, I won't mark this thread as answered untill you say it works for you too.
.menu-bar { -fx-background-color: transparent; -fx-font-family: Baumans; -fx-font-size: 14px; -fx-text-fill: #00CCFF; } .context-menu { -fx-font-family: Baumans; -fx-background-color: transparent; -fx-font-size: 12px; -fx-text-fill: white; }
5. Re: Using custom fonts on MenuBar Menu and/or MenuItemjsmith Mar 14, 2012 7:11 PM (in response to 921851)Very cool. That loaded the custom font and styled it using css :-)
I placed the loadFont call inside an overridden Application init method to make sure it was invoked before anything much happened in the application.
When I used the styles you provided the colors of the fonts in the menus did not come out right, they just remained their default colors and not the -fx-text-fill color.
Font.loadFont(CustomFontTest.class.getResource("TRON.TTF").toExternalForm(), 10);
To get the right colors I had to use slightly modified css which explicitly set the -fx-text-fill on the label styleclass.
Nice that the CSS sized the fonts fine.
.menu-bar { -fx-background-color: transparent; -fx-font-family: TRON; -fx-font-size: 40px; } .menu-bar .label { -fx-text-fill: #00CCFF; } .context-menu { -fx-font-family: TRON; -fx-background-color: transparent; -fx-font-size: 12px; } .menu-item .label { -fx-text-fill: red; }
Even when the font was loaded at size 10, the font was resized correctly to what was specified in the CSS fx-font-size specifications.
Inline styling of a label via css using a Font loaded during application initialization also worked fine:
Label testControl = new Label("TRON"); testControl.setStyle("-fx-font-family: TRON; -fx-font-size: 120;");
6. Re: Using custom fonts on MenuBar Menu and/or MenuItem921851 Mar 14, 2012 7:33 PM (in response to 921851)Yes! Seems that using
Registers the Custom Font and then we can set it using a css file. Also:
Font.loadFont()
"Place the loadFont call inside an overridden Application init method"
Ensures we can access it from css. Marking this as Answered. Thank you JSmith for all the support! | https://community.oracle.com/message/10209688 | CC-MAIN-2017-13 | refinedweb | 1,526 | 66.94 |

Hey guys,
Thanks for the help on the interface stuff. Got it working.
Running into another problem now. I have a small Java based execution harness that will load in some Jython code and execute it. The Jython makes a call out to some other Jython code I have that does some XML parsing using minidom. I keep getting the following error whenever it goes to run:
Exception in thread "main" Traceback (innermost last):
File "<string>", line 8, in ?
File "c:\project files\JBI\Fuselets\.\jbiWrappers.py", line 25, in ?
File "c:\project files\JBI\Fuselets\XmlSerializer.py", line 23, in ?
ImportError: no module named xml
Line 23 is:
import xml.dom
I've got Jython.jar in my java classpath, and the code runs just fine if I execute it directly in Jython.
Any ideas what I'm missing or doing wrong?
Thanks!

In C#, namespaces are used to logically arrange classes, structs, interfaces, enums and delegates. The namespaces in C# can be nested. That means one namespace can contain other namespaces also.
In C#, namespaces are used to logically arrange classes, structs, interfaces, enums and delegates. The namespaces in C# can be nested. That means one namespace can contain other namespaces also. The .NET framework already contains number of standard namespaces like System, System.Net, System.IO etc. In addition to these standard namespaces the user can define their own namespaces.
Declaring a Namespace
The C# language provide a keyword namespace to create a user defined name space. The general form of declaring a namespace is as follows.
namespace
For example:using System;namespace Rajesh.Csharp.Codes{class MyClass{public MyClass(){Console.WriteLine("My Class");}} class MyClient{public static void Main(){MyClass mc = new MyClass();// Displays 'My Class'}}} It is not possible to use any access specifiers like private, public etc with a namespace declarations. The namespaces in C# are implicitly have public access and this is not modifiable.
The namespace elements can't be explicitly declared as private or protected. The namespace allows only public and internal elements as it members. The default is internal.
The following code doesn't compile in C#, since the class inside the namespace is declared as private.
namespace Rajesh.Csharp.Codes{private class MyClass{}} Accessing Namespace Members The namespace members can be accessed by using a fully qualified name, which including the namespace name and member name separated by dot(.) from outside the namespace. For example using System;namespace Rajesh.Csharp.Codes{class MyClass{public MyClass(){Console.WriteLine("My Class");}}} class MyClient{public static void Main(){//Using the fully qualified name to access the namespace member.Rajesh.Csharp.Codes.MyClass mc = new Rajesh.Csharp.Codes.MyClass();}} But in order to save developer from typing fully qualified name every time, the C# provides another keyword using to define some aliases to namespaces. Then while writing our code, we just refer the classes with their class name only. During compile time, the compiler will map all the class names with aliases to reach at the fully qualified name of the class. Once the fully qualified name has been found, it is used to convert the code to IL code. Remember that in IL code all classes, interfaces, enums and delegates are referenced with their fully qualified name.
An example of using is shown below. using Rajesh.Csharp.Codes;MyClass mc = new MyClass(); Remember that inside C# namespaces, it is possible to use the keyword using.
The same namespace can be span over multiple lines as follows.
using
In C#, namespaces can be nested with each other as showing below.
These are some of impoetant namespaces of .NET framework. Remember that the above list is a not complete one. | http://www.c-sharpcorner.com/UploadFile/rajeshvs/WorkingWithNamespacesInCS11112005044200AM/WorkingWithNamespacesInCS.aspx | crawl-002 | refinedweb | 471 | 50.43 |
PyCharm Professional 2020.2
Windows 10 Professional 19041.685
Background:
I downloaded the folder from:
Put it in D:\Dropbox\Code\course-nlp-master
I right clicked the course-nlp-master from Windows Explorer, Open Folder as Pycharm Project
Settings-> Build, Execution, Deployment -> Console -> Python Console
Working Directory: set it from Blank to D:\Dropbox\code\course-nlp-master
Problem 1:
import os
os.getcwd()
Got:
D:\\Dropbox\\code
when I wanted D:\\Dropbox\\code\course-nlp-master
Problem 2:
in 2-svd-nmf-topic-modeling.ipynb, there is an image
img src="images/document_term.png" which does not display in the right panel
I changed the working directory to D:\\Dropbox\\code\\course-nlp-master using os.chdir()
and changed the code above to img src="\images\document_term.png"
However, it still fail to display.
My question is, what is the best setting to use in PyCharm so that I can display all the images in all Jupyter notebook with the least amount of changes to the ipynb files?
note: I opened the same notebook in Jupyter Notebook (Anaconda) and the images display correctly.
Thanks!

Unix socket (AF_UNIX) is now avalible in Windows 10 (April 2018 Update). Please add Python support for it.
More details about it on
I've been asked by my team to investigate what is required to enable AF_UNIX in Python.
Is anyone else actively investigating this? I did a prelinary investigation and the impact on test in test_sockets was pretty simple.
However there were 26 test failures in test_asyncio tests, with only the naive changes to all AF_UNIX to work with the socket class on Windows.
The first failure I looked at was caused by ProactorEventLoop in windows_events.py not providing a windows-specific version of create_unix_server. This results in the code falling back to AbstractServer.create_unix_server which raises NotImplementedError.
Have you upgraded the building SDK that supports AF_UNIX?
And should remove AF_UNIX flag at runtime on systems older than Windows 10 1804, see issue32394.
It would be nice to investigate the habit of using AF_UNIX in Python code on GitHub:
If adding this flag will break a lot of code, due to lacking supports to datagram, maybe we should not add AF_UNIX at once, and waiting for full support to AF_UNIX.
I don't know if datagram support is coming to AF_UNIX on Windows.
The changes will only add the flag on Windows, and will enable stream sockets to use AF_UNIX on Windows. In mind this isn't breaking datagram support. It is true that it's a subset of what appears to be supported on Linux/Unix.
The current AF_UNIX address family of Windows10 doesn't support datagram, adding this flag may break some cross-platform code:
...
So I'm -1 on adding AF_UNIX personally.
I thought a compromise proposal:
- if (building SDK >= 1804 and run-time Windows >= 1804), add a undocumented flag _WIN_AF_UNIX, its value is equal to AF_UNIX.
- only use _WIN_AF_UNIX in stdlib, this is a black-box optimization.
- if someone really need high performance, he/she can uses this undocumented flag privately.
If one day Windows support full AF_UNIX, we can remove _WIN_AF_UNIX and add standard AF_UNIX.
Most of those examples would break today if run on Windows, though (AttributeError). So they'd just continue to break, probably with a different error (I'm not clear what happens if we specify SOCK_DGRAM with this change).
Having an undocumented field doesn't really help much - what we want is a documented field with a different name, perhaps WIN_AF_UNIX? (I think we need to keep the "AF_" prefix for real values and not mess up the namespace ourselves.) That way we can document that it matches AF_UNIX when defined on Windows, but will not trigger existing code that checks for the presence of AF_UNIX. Then we'll have to update the standard library to use either/both values where supported.
If you try to create a datagram socket with the current AF_UNIX changes on Windows the error is:
OSError: [WinError 10047] An address incompatible with the requested protocol was used
All of the examples given will fail to load with AttributeError on Windows because socket.AF_UNIX is not a valid attribute on Windows.
I think it's possible that there is code that detects whether AF_UNIX is an attribute on socket or not and does something different on Windows, but I haven't seen an example of it so far.
I can make the changes to WIN_AF_UNIX when I continue working on this, just in case there is portable code out there somewhere.
> I think it's possible that there is code that detects whether AF_UNIX is an attribute on socket or not and does something different on Windows, but I haven't seen an example of it so far.
One of the test suites linked above had a skipUnless(hasattr(socket, 'AF_UNIX')) on the whole class, and at least one test assumed that it could use datagram support, so there's the example. | https://bugs.python.org/issue33408 | CC-MAIN-2021-21 | refinedweb | 666 | 62.07 |
In some ways SharePoint 2007 was a brand new incarnation of the SharePoint product. For the very first time, ASP.NET 2.0 was applied properly to the product. Things such as master pages, membership providers, sitemap providers etc. were used heavily in SharePoint. As a result, SharePoint 2007 got a whole new developer story to it. But in some ways it was a first version of a big product, so the development story left us wanting for more. Wanting for more because in some ways the API wasn’t ideal, and most certainly the development tools were somewhere between non-existent to bad. Diagnosing SharePoint errors was another frustrating story many have endured. What has changed in SharePoint 2010? Let’s find out.
Much better development tools
Developing for SharePoint 2007 meant either handcrafting your own project structures, or having community products such as WSPBuilder greatly help you out, or use tools released by Microsoft such as VSeWSS. It is fair to mention that VSeWSS was released very late in the product cycle. The whole world was already using WSPBuilder. But one very good reason for picking VSeWSS over WSPBuilder was the possibility being able to the current version of tools built into Visual Studio 2010.
I am very happy to say that the Visual Studio 2010 built for SharePoint 2010, actually work! They are actually good. You no longer need any community tools, or visits deep into hackistan to get simple things done. Of course it is important to remember that the Visual Studio 2010 tools are built for SharePoint 2010 only, you can’t use them for SharePoint 2007 platforms. Now, you still need your own SharePoint development machine, but now that machine can be Windows 7 or Windows Vista. Client operating systems are supported for development reasons only. Also, as much as these tools try and wean you away from the 14 hive, now known as SharePoint root, directory structure, believe me, you still need to know it. Not only that, there is still no replacement for basic SharePoint fundamentals, such as what happens when you deploy a WebPart.
For instance, writing a WebPart in the new Visual Studio 2010 tools is a perfect example. Earlier, using WSPBuilder, you had to craft up a directory structure that would literally represent the feature structure in the 12 hive. Then you had to meticulously hand craft the XML inside feature.xml, another set of XML inside your elements.xml, in which you had to remember that you had to deploy a .webpart file using a module into the _catalogs/wp, with a list ID of 113. Then inside of the .webpart file you had to remember to have a certain XML structure so your WebPart would be properly available in the right group, with the right icon and the right name. And then if anything was misspelled, there were usually no errors. Oh and you had to remember the feature had to be scoped to a site collection, which is really referred to as “Site” in the XML. What a mess!
In comparison, Visual Studio 2010 tools let you write an equivalent WebPart using the following steps:
- Create an Empty SharePoint project
- Right click, add a new WebPart.
Or, if you prefer, just create a Visual WebPart Project, though that requires you to write your WebPart as a farm solution in the current toolset. Now, you still have to know the basics – you have to know that a safecontrols entry will be created for you, you have to know that a .webpart file is deployed that you are responsible for the cleanup of, and you have to know the fundamentals of Sandbox solutions vs. Farm Solutions which is a new, and very important concept in SharePoint 2010.
Reworked Architecture – Sandbox Solutions
When you create a SharePoint Project in Visual Studio 2010, you are presented with the following dialogbox:
There are two questions being asked here. The first is, which local site do you want to use for debugging? This is the same machine that you are running SharePoint on. Some may wonder why Visual Studio has to ask such a silly question, because after all this is always your local machine. The reality is, sometimes you may have alternate URLs setup even for your local site, and that may be important in certain development tasks. Secondly, the site collection you intend to debug your code on may not be a root level site collection. Finally, if you have multiple web applications, this tells Visual Studio which w3wp.exe process to attach to for debugging. Providing the URL tells Visual Studio what w3wp.exe to attach to, in order to debug your code. So you see it's not such a silly question after all.
That was my marketing side talking. Although in simplistic scenarios F5 debugging will work, in many situations you will still find yourself attaching to processes. For example, sometimes your code may not run inside w3wp.exe. It may run under a separate EXE called SPUserCodeService.exe. That would be a sandboxed solution which I will cover in more detail later in this chapter, but for now, that is the second question Visual Studio wishes you to answer. Therefore, the second question is whether you intend to create a sandboxed solution or a farm solution? A farm solution is what used to be a solution in SharePoint 2007. It had unfettered rights to your SharePoint farm, so it could do anything. Sounds like a good proposition, but this created an immense headache for the two poor farm administrators in your organization who were then expected to somehow review every line of code being deployed to the server. A task they intend to get around to doing right after they solve world peace and hunger. Frankly, it is unreasonable to expect two overtaxed IT Pro people to review every single developer's code. Plus since some developers can be really crafty with custom code, while being necessary, is the number one reason for support issues on SharePoint in general.
In response, Microsoft came out with the concept of sandboxed solutions, sometimes also referred to as user solutions or user code. Put simply, a sandboxed solution is what runs inside a secure sandbox. It runs inside a separate process from W3WP.exe, and it is protected by a CAS policy, so you no longer have to craft custom CAS policies. Also, in addition to being more secure, it is also more easily monitored. Being more restricted, secure, and being more easily monitored, sandboxed solutions can now be deployed with more confidence. Thus, they are now deployable and can be activated right through the site collection. The Farm Administrator doesn't even need to be bothered, because he is monitoring the solution anyway. You cannot break his farm by deploying a sandbox solution, so everyone can be at peace, no more IT-Developer wars.
If there are two things you carry from this article about Sandbox Solutions, they are:
- Secure by default, you should create sandboxed solutions when you can. Creating a farm solution unnecessarily is bad practice. Perhaps a better way of saying this is, create farm solutions only when you cannot create a sandboxed solution.
- You can choose to change your mind later, i.e., change a sandboxed solution to a farm solution or vice versa if you need to.
Oh and did you hear about the cloud? Microsoft is all about the cloud these days, and so is everyone else. I really doubt you’ll be able to deploy farm solutions on SharePoint online.
Client Side APIs
What are good development tools without a decent API? We live in a changed world, 5 years ago, with no facebook, no google maps, no foursquare, it was actually possible to get lost and avoid people you didn’t like! Now you have all these crazy applications that feel like desktop applications, but they run right through the browser. So, finally, for the very first time in the history of computing, you have the power of desktop apps, with no installation hassle, and complete security! How did we do it?
We did it using client side technologies, specifically JavaScript, Flash, and Silverlight. It is no surprise therefore that SharePoint 2010 includes amazing support for both JavaScript and Silverlight. The biggest proof in the pudding of course is Microsoft’s own commitment to these products. Core features of SharePoint 2010 use JavaScript heavily. And they do so in an “upgrade to Silverlight” mentality. For instance, if you use the word or powerpoint office web apps, everything will work if you don’t have silverlight. But soon as you install silverlight, the user experience becomes so much better. Fonts start to use cleartype rendering, pages load faster, etc. Visio services does that too, it renders everything as .PNG if you don’t have silverlight. But prefers to render everything as .XAML.
So the question is, is any of this power available to you? Certainly! It is available to you in 3 forms on the server side.
- The Client Object Model, which gives you a whole new namespace at Microsoft.SharePoint.Client, which looks and feels like a subset of the server side API with two big differences.
- It runs in the client, which can be .NET CLR application not running on the server, or JavaScript, or Silverlight
- It allows you, the developer to control when you round trip to the server, and what is done during those round trips. Concepts such as concurrency management, object identity are built into its API.
- The REST API, which exposes every SharePoint list over a RESTFUL interface. Which means you can use simple HTTP Verbs such as GET, PUT, MERGE, DELETE, and POST to query and update data on the server, or even generate proxies and use higher constructs such as LINQ to work with server side data.
- Custom WCF services, because both the client object model, and the REST API are built using WCF – you can write your own services if you wanted to.
And on the client side, you can choose to use .NET CLR, Silverlight, Flash, jQuery, iOS, Java, basically whatever you want! This will truly usher in a new era of apps.
Better Diagnosis Tools
An “unexpected error has occurred”. Well I guess, I wasn’t expecting an error in the first place, was I? Diagnosing SharePoint errors can be a black art, there are many places to look at when an error happens. This is because the product is inherently big and complex with a lot of moving parts. So I was really excited to see some improvements on the error logging and tracing side. SharePoint’s central logging capability is referred to as ULS, or the Unified Logging Service. The ULS, is a bunch of text files, that wrap around a certain character length, but suffice to say, each file is wide enough that it doesn’t fit properly on a 30” monitor in 8pt font even. Looking for your error inside the ULS can be almost like looking for a needle in a haystack.
Well, not anymore! In SharePoint 2010, you get an error message that looks like this,
Note there is a Correlation ID there? Now using that correlation ID, you can easily trace down your error needle in the ULS haystack. And there are tools available to help you do that. One such tool is the ULS Viewer which you can download for free from code.msdn.microsoft.com/ulsviewer. And guess what, that tool will work with SharePoint 2007 as well. And in general, there are many other such enhancements in the logging framework, and diagnosis of issues in your SharePoint installation.
Summary
SharePoint 2010 is quite different from SharePoint 2007. One article is merely touching the tip of the top molecule of the iceberg. Come join us for more such information at the DevWeek SharePoint 2010 post conference on Friday, March 18th, 2011 with Sahil Malik.

In this discussion I will be tackling the whys and wherefores of creating COM servers in Python. In the first section the focus will be on COM servers. In the second section and third sections, I will detail the necessary steps for creating a COM server in Python. The fourth section will provide a real world example of developing a COM server and calling it from Visual Basic. That’s the outline for this discussion.
More About COM
In the world of COM there is a clear line of separation between accessing COM components and implementing COM objects. While accessing COM objects, method calls are made on them, provided externally using the interfaces exposed by the COM object. When implementing COM objects, which are also known as COM servers, the object has to publish or expose its interfaces so that external clients can use them.
This difference is evident from the way the interfaces and methods implemented are utilized either to access a COM component or expose the functionalities of a COM component. The interface under consideration is IDispatch. Programs that use an IDispatch object must call the GetIDsOfNames() and Invoke() methods to perform method calls or property reference, whereas the objects that wish expose their functionalities via IDispatch must implement the GetIDsOfNames() and Invoke() methods, providing the logic for translating between names and IDs, and so on. In the world of PythonCOM, the former is called client-side COM and the latter is server-side COM.
The next topic I will cover is the types of server-side COM objects. There are three types of server-side COM objects:
- In-Proc Server
- Local Server
- Remote Server
The difference in the types is based on where the COM server is executing. The COM server could be executing in the process space of the client, in its own separate process space, or on a different system. Here are the details.
In-Proc Server
When the COM server is loaded into the process space of the client, it is known as an In-Proc server. In other words, "A Component Object Model (COM) object that is executing in the same process space as the user of that object is called an In Process object (InProc for short)." An In-Proc server is implemented as a DLL in other languages.
Local Server
When the COM server is loaded and executed in its own process space, it is called a Local Server. By definition, "When the user code is executing in the process space of Application A, and the COM object is executing in the process space of Application B, interface method invocations by A on interfaces implemented on B clearly must cross process boundaries, then the COM objects in Application B are cross-process objects, or Local Servers." A Local Server is implemented in the form of an EXE.
Remote Server
When the COM server is implemented as an EXE but executed on a remote machine, it is known as a Remote Server. Remote Servers come under the heading of Distributed COM or DCOM.
The important aspect of these differences is that they are mutually inclusive. That means a COM component can be registered as a combination of any of the above three types. Now that the types of COM servers have been introduced, let’s see how to develop COM servers in Python step-by-step.
{mospagebreak title=Developing COM Servers Step by Step}
Developing a COM server in Python is easier than in any other language. If the process is broken down into steps there are primarily two steps, which are developing the class and annotating the class with attributes. Furthermore, in the first step you must decide on which model the class must be based.
Developing the class
The philosophy of COM is that a fixed interface must be built and the class must be modeled around it. In essence, once the interface has been defined, it must not be changed. To work with this philosophy there are three design patterns that can be used. They are:
- COM base class, pure Python subclass
- Pure Python base class, COM subclass
- COM interface, Python delegate
The COM interface, Python delegate pattern is the most commonly used. The reason for this is the ability to develop the class first.
In the pattern of a COM base class, pure Python subclass, a base class has to be defined and exposed as a COM server. The methods in the base class perform no tasks. The base class works as a COM interface. Then a sub class, which implements the base class, has to be developed; this class provides the actual services. In other words a class that implements the base class performs the tasks. This pattern is most appropriate when designing a class whose main function is to be used from COM and not from Python.
Now let’s look at a pure Python base class, COM subclass pattern. It is in a way the opposite of the previous pattern. Here, the existing COM class is inherited from a Python base class. The COM class can be differentiated by the the attributes used to annotate the class, which will be discussed shortly.
Finally, let’s examine the COM interface, Python delegate pattern. In this case, the COM interface is defined. The class that defines the COM interface has variables internal to it that point to the pure Python counterpart. The Python counterpart is known as the delegate. The methods of class that represent the COM interface translate their arguments, return values as needed, and forward them to the delegate.
Let’s take the third pattern as an example. For the sake of the example, suppose there is a BookSet class that implements the methods of the COM interface. Now if the third pattern is applied to define a COM interface, it would look like this: __BookSet variable points to the pure Python class BookSet. This is how it delegates the task to the pure Python class. You will observe that there are certain attributes such as _reg_clsid_. The explanation of these attributes is coming up next.
{mospagebreak title=Annotating the Class with Attributes}
Every Python class representing a COM interface must expose itself as a COM object. To achieve this, the PythonCOM framework requires certain attributes to be associated with the Python class that needs to be exposed as a COM object. There are three main attributes, which are:
- _public_methods_
- _reg_progid_
- _reg_clsid_
All of the above attributes are required in exposing a Python class as a COM object – from simplest to the most complex COM objects.
The _public_methods_ attribute takes a list of all those methods that need to be exposed via the COM. The _reg_progid_ attribute is used to assign the ProgID for the new object, that is, the name that the users of this object must use to create the object. It is the human readable name of the object. Finally, the _reg_clsid_ attribute sets the unique CLSID for the object. These IDs must not be copied. Instead new ones should be created using pythoncom.CreateGuid().
Let’s take a look at the same example of the COM server: _reg_clsid_ contains a 32 bit class id for the object. The _reg_progid_ contains the human readable name using which the object can be called. Here the _public_methods_ contains the list of all the methods exposed via COM. Here there is only one — double. That completes this section. In the next section, I will be creating a real world example and call it from Visual Basic.
{mospagebreak title=Creating COM Servers in the Real World}
In the previous sections I introduced the basic requirements for creating a COM server in Python. Now let’s put the concepts into practice. The example will provide a simple functionality — splitting a given string. There are two parts of the application:
- PyCOMServer.py – The COM server implemented in Python
- SampleClent.vb – The client implemented in VB
Let’s start with the server. First let’s define the Python class contained in PyCOMServer.py – PythonUtilities
class PythonUtilities:
def SplitString(self, val, item=None):
import string
if item != None: item = str(item)
return string.split(str(val), item)
This class defines a single method, SplitString, that takes two arguments: item, which is the string to be split; and the value contained in val on the basis of which string has to be split.
The next step is to embed the attributes so that the class can expose its functionalities through the COM:
class PythonUtilities:
_public_methods_ = [ ‘SplitString’ ]
_reg_progid_ = "PythonServer)
Since there is only one method that needs to be exposed, the list for _public_methods_ contains only the SplitString method. Next, the name by which it can be called is given via _reg_progid_ which is PythonServer.Utilities. Finally the class id generated using pythoncom.CreateGuid().
Next is the main code that is required to register and run the COM server.
class PythonUtilities:
_public_methods_ = [ ‘SplitString’ ]
_reg_progid_ = "PythonDemos)
# Add code so that when this script is run by
# Python.exe, it self-registers.
if __name__==’__main__’:
print "Registering COM server…"
import win32com.server.register
win32com.server.register.UseCommandLine(PythonUtilities)
Next comes the client. For developing the client start the Macro editor either in MS Word or MS Excel. Enter the name for the macro. The implementation of the macro is as follows:
Set PythonUtils = CreateObject("PythonDemos.Utilities")
response = PythonUtils.SplitString("Hello from VB")
for each Item in response
MsgBox Item
That brings us to the end of this discussion. The application developed doesn’t apply the design patterns, as certain advanced aspects of COM programming have to be covered yet. That’s the agenda for the next part: advanced aspects of COM servers.

Install Precompiled OpenCV 4.5 on Raspberry Pi
OpenCV is an open-source library for image processing, computer vision, and machine learning. OpenCV is widely used for object detection, gesture recognition, motion tracking, face detection and recognition, image segmentation, medical image analysis, license plate recognition, and so on.
This tutorial shows how to install precompiled OpenCV 4.5 on Raspberry Pi.
Debian package
We have created Debian package (
.deb) that contains precompiled OpenCV 4.5.3 binaries for Raspberry Pi 3 Model A+/B+ and Raspberry Pi 4 Model B. Binaries are compatible with Raspberry Pi OS Buster (32-bit). We have created a release on GitHub repository and uploaded
opencv.deb package.
OpenCV was built with the following features:
- NEON optimization
- VFPv3 optimization
- TBB library
- FFmpeg library
- GStreamer library
- Python 2 and Python 3 bindings
You can found detailed build information on GitHub repository.
We tested on Raspberry Pi 4 Model B (8 GB).
Install OpenCV
Connect to Raspberry Pi via SSH. Download the
.deb package from releases page of the repository:
wget
Execute the following command to install OpenCV:
sudo apt install -y ./opencv.deb
We can run
opencv_version command to check version of OpenCV:
opencv_version
The
.deb package is no longer needed, you can remove it:
rm -rf opencv.deb
Testing OpenCV (C++)
Before starting, make sure you have installed GNU C++ compiler:
sudo apt install -y g++
Create a
main.cpp file:
nano main.cpp
When a file is opened, add the following code:
#include <opencv2/opencv.hpp> int main() { std::cout << cv::getBuildInformation() << std::endl; return 0; }
Execute the following command to compile code:
g++ main.cpp -o test -lopencv_core
The core functionality of OpenCV has been used. So we need to link
libopencv_core.so shared library.
Run a program:
./test
Testing OpenCV (Python)
Create a
main.py file:
nano main.py
Add the following code:
import cv2 print(cv2.getBuildInformation())
Run a script using Python 3:
python3 main.py
Python 2 can be used as well:
python main.py
Uninstall OpenCV
If you wish to completely remove OpenCV and related dependencies, execute the following command:
sudo apt purge --autoremove -y opencv | https://lindevs.com/install-precompiled-opencv-on-raspberry-pi/ | CC-MAIN-2021-31 | refinedweb | 357 | 60.21 |
Book.
The author has over 16 years experience in IT and enterprise web application development. He has deployed Ext-based applications in large corporations such as Marriott International, Lockheed Martin, JPMorgan Chase, and the Financial Industry Regulatory Authority. In his spare time, Jay enjoys assisting the Ext JS community forums, where he is one of the top posters not employed by Ext JS LLC (over 13,000 posts).
The book includes information on:
- Building dynamic UIs using core components like panels with layouts
- Creating live forms that submit data without a page refresh
- Effective UI using trees, menus, and toolbars
- Creating custom composite widgets
- Full coverage of Ext JS 3.0
The reader will be guided through the Ext component model and layouts, learn how core components, such as the Container class, serve as building blocks for building complex user interfaces. The book covers Ext utility classes, AJAX, Observable (the Ext events model), DOM helpers and Function Helpers and illustrates how use of JavaScript Object Notation (JSON). It also examines the proper ways to customize or extend Ext widgets.
The book’s publisher, Manning, made an expert available to InfoQ which includes the contents of the 3rd chapter, “The Component model and lifecycle”.
InfoQ readers can take advantage from a 40% discount on Ext JS in Action using the promo code “infoq40”, courtesy of the publisher.
InfoQ had a Q&A with the author about his new book:
InfoQ: Hi Jesus, would you like to tell us a little bit about yourself and how you came about writing a book about Ext JS?
Jesus: I began with Ext JS back in early 2006, when it was a set of extensions for the YUI library. Back then, it was known as “YUI-ext” and was developed as a side project by a little known guy named Jack Solcum. Like many newcomers to the framework, I was first attracted to the data grid. What sold me to the library was the documentation, which is probably the best Ajax framework API to date.
Soon after my introduction to the framework, I decided to become a specialist and focus my career, becoming an independent consultant. After this decision, I started becoming active in the early community, spending a lot of my own time in the help forums, answering people’s questions or working through their problems with them. By doing this, I was able to learn much more about the framework than I would by just doing application development. To this day, this still gives me a means to learn a lot while contributing to the community by helping others.
Being on the Ext JS forums has earned me a bit of a reputation, and is how I got onto the radar of Michael Stephens from Manning. He contacted me, along with other active community members, to request a review of a book proposal. After reading the first few lines of the proposed table of contents, it was clear to me that this book was not an “Ext JS in Action”. After submitting my thoughts and recommendations on the proposed TOC, Michael held a post-review meeting and that’s where he asked if I would be willing to submit a TOC of my own, and I did. Fast forward two years, and here we are.
InfoQ: What is Ext JS and what is the problem that it tries to solve?
Jesus: Ext JS is a UI library for the web. It is light years ahead of any UI library on the market because it abstracts developers from having to write a single ounce of HTML if they don’t want to, yet has the flexibility to allow any developer to Extend the widget libraries or create real plugins via a simple, yet powerful plugin architecture.
Ext JS solves the problem of managing HTML and CSS to provide a UI look and feel that rivals desktop applications. It empowers developers to inject widgets into existing HTML web pages or develop extremely rich Enterprise class RIAs, some of which are used in mission critical applications, such as real time monitoring and managing of network infrastructures.
The framework also has quite a lot of utilities, such as the data Store, templates and xTypes that further empower application development capabilities.
InfoQ: In your book you mention that the Component and Container models that Ext JS follows is what makes it stands out from the rest of the Ajax libraries. Would you like to elaborate on that?
Jesus: The Component and Container models (among other things) make Ext JS quite unique among competing Ajax libraries because they bring structure to the UI portion of the library. Without it, Ext JS would be not much different from other Ajax Libraries.
The Component model introduces the “Component Lifecycle” to the framework and brings a set of well-defined and dependable behaviors to the widgets. It is broken up into three phases, Initialization, Render and Destruction. Initialization occurs whenever you instantiate a new instance of a component. The Render phase occurs when the Component is rendered or painted on screen. Lastly, the Destruction phase allows the Component to perform cleanup tasks, such as the removal of any injected HTML nodes and purge any event listeners.
The Container model allows Components to manage other components in a parent-child relationship model. With the Container model, developers can easily create dynamic UIs by leveraging its add() or remove() methods to add or remove one or more child items. To manage the visual organization of child items, Containers use a Layout.
InfoQ: Would you like to tell us a little bit about how you use Ext JS in your work? How do you see other people using it. Are there types of RIA applications where it is not a suitable solution? Is Ext JS suitable for mobile web applications?
Jesus: I typically use Ext JS to develop applications for a wide variety of customers. My latest task was to develop a screen to manage member information for one of my customers. Because Ext JS is so versatile, I’ve been able to leverage it to develop a wide variety of applications from a custom UI merging data from IBM’s Tivoli Enterprise Console and HP Universal CMDB to a front-end for EMC’s Documentum product. I’ve even developed applications to help organizations develop content for exams.
Developers can leverage Ext JS pretty much to develop whatever they need in a RIA. Throughout its lifespan, I’ve seen such a wide range of applications, most of which were business-centric.
Ext JS, itself is not geared towards mobile web development, but its sibling Sencha Touch is. I have seen and toyed with Ext JS applications running on an iPad with limited functionality. It does not contain support for touch gestures that make mobile applications useful and its UI theme is certainly not mobile-centric.
InfoQ: How good do you see Ext JS perform on the various browser platforms? What do you have to say to people that might be reluctant to use it because of current compatibility issues, or fear to lose compatibility because of future upgrades?
Jesus: Boy that’s a loaded question (smile). I would have to say that Ext JS performs the best given the best environment to run in. Generally, it has been my experience that Ext JS runs best in Webkit-based browsers, and absolutely the worst in IE. Naturally, the browser has a lot to do with this perception, but there were some issues in the early release of the Ext JS 3.0 code base that contributed to the slow performance in IE.
It’s a known fact that general performance for the initial release of Ext JS 3.0 was much less than 2.x, but it certainly has gotten better with subsequent releases. The Ext JS team has been pretty sensitive to the feedback that various customers and community members have been giving them and have been making necessary changes to try to squeeze as much performance as possible without limiting functionality.
I also have to throw in that performance of the framework also as a lot to do with how developers implement it. Newer developers tend to make simple mistakes, such as what is known as “overnesting”. This is when someone unnecessarily wraps a widget with a parent widget, adding an unnecessary layer of effort for the UI. Another common mistake is loading thousands of records into a view (GridPanel, DataView, ListView or ComboBox), which can lead to the “JavaScript is running too long” message on your screen.
Upgrading from the 2.x branch to the 3.x version is pretty easy. This also holds true with upgrading within the 3.x family. From my experience, most of the problems people have with upgrading is that they have code that are depends on, uses or overrides private members, which are subject change. They are marked private for a reason. Obviously, this practice is not recommended by the team or even by veteran developers and is something you should work to avoid to allow for easier upgrades.
InfoQ: What is your preferred process for developing an Ext JS application? What tools do you use and how good do you think the current JavaScript/HTML tool stack is?
Jesus: I typically develop applications locally on my laptop to make the feedback loop as rapid as possible. I use a pattern to developing applications following the framework’s patterns, with somewhat of a twist. For instance, I like to lay out the files in the file system (and project) according to the namespace of the class. This allows for quick access to files. This same pattern is applied to any plugins, user extensions (ux) or overrides that are applied to the framework.
There are quite a few good tools to develop your JavaScript code, but I prefer to develop my applications with Jetbrains’ Intellij IDEA. While it’s not the fastest tool, it is the one that I have fallen in love with. It allows me to do things like have dynamic code auto completion and refactoring on class members. It also includes its own debugger for JavaScript, though I typically don’t use it.
I’ve heard great reports from developers using tools such as NetBeans or even Aptana, which is a wrapper for Eclipse.
InfoQ: Does using a substantial JavaScript client-side framework like Ext JS pose difficulties in debugging? When things go wrong how do you debug?
Jesus: It can pose serious difficulties for a lot of reasons. The first typically is that developers will use ext-all.js (concatenated and minified version of the framework) instead of ext-all-debug.js (concatenated with white space preserved and comments removed) when developing. If an exception is thrown by the JS interpreter, the message will typically be extremely cryptic due to the nature of JS minification. If the error is viewed in IE, it generally will make no sense what so ever and add to your frustration. Generally, to remedy this, you would want to develop your apps using the uncompressed ext-all-debug.js file, which will make the error message a tad less cryptic and you can at least get an accurate line indication for which the exception occurred.
Whenever an exception is generated by ext-all-debug.js, I typically will try to view the area where the exception occurred. From there, I scroll up to find the method that the exception was generated in, then scroll up again to find the class that the method belongs to. Nine times out of ten, for me at least, the problem is usually between the keyboard and the chair.
I have to say that because I use Webkit, viewing hundreds of thousands of lines of JS in the ext-all-debug.js file is a breeze. Sadly, the current state of Firefox prevents Firebug from reaching the same level of performance, which is why I moved to Webkit from Firefox a few months ago. I’ve tried the same in IE8 and ended up pulling a lot of my hair out.
InfoQ: Are you using any functional testing methods in your work? How do you go about this issue?
Jesus: Unfortunately no. I have thought about injecting unit testing into the application development cycles for my customers, however time always seems to be an issue. The amount of time spent writing tests can save you tons of time in bug fixes in the future, but making that initial investment is difficult for my customers.
InfoQ: In your book you describe several components that you get out of the box, when using Ext JS. Is it easy to extend those? How easy is it to create new components?
Jesus: I find it easy to extend the framework, but then again, I’ve been using it since 2006. Ext JS is developed to be extended and have plugins written for it and demonstrates some of the best JavaScript development patterns that I’ve seen in any competing framework.
The level of difficulty for extending components is relative to the developer’s experience with Object Oriented JavaScript patterns and the framework. You absolutely need to be experienced with OOJS (prototypal inheritance) to be able to extend the components. afterall, if you don’t understand prototypal inheritance, the concept of extending inside of JavaScript will seem foreign to you. You also need to be able to understand concepts like execution context and how the ‘this’ keyword is used.
Likewise, you should be familiar with the Component, Container and layout models to extend widgets properly and prevent common mistakes like overnesting. Good knowledge other areas of the framework helps as well.
I bring all of this up because I’ve seen so many new developers come to the framework with grand dreams of building complex and elaborate applications. Yet they find themselves stumbling on simple tasks, all because they do not have the foundation necessary to fully understand or utilize the framework.
For people who want to get up to speed on JavaScript, I suggest “Pro JavaScript Techniques” by Dustin Diaz (Apress). This will explain a lot about modern JavaScript programming, allowing you to get a clearer picture of what some of the advanced code you see in the wild.
InfoQ: How do you see Ext JS evolving with the emergence of HTML5?
Jesus: The one thing that has been great about the Sencha team is that they are always looking ahead. They have been working hard to bring Ext JS HTML5 and CSS3 compliant for version 4.0, which is due out some time next year. Ext JS 4.0 shares the same base code as Sencha Touch, which already has great support for these technologies.
InfoQ: What do you think would be the most valuable take away from your book for people that have just found about Ext JS and what for seasoned users of this frameworks that want to take it to the next level?
Jesus: For the newbies to the framework, I think getting a deep understanding of the Component, Container and Layout models is a great take away. I tried my best to explain them in plain English as possible and have gotten pretty good feedback from readers.
For the veterans, I’d have to say that the most valuable take away from the book has to be the last three chapters (15-17). Chapter 15 gives readers the basics of creating extensions with Ext JS and developing plugins using real-world examples. The last two chapters are dedicated to constructing a fictional application and walk readers through core decision making processes, such as laying out a namespace and developing abstract classes to reduce duplicate code.
Developers from many experience levels have given me positive feedback from after reading these chapters and have said that some the concepts have helped them in various ways when developing applications.

One of the issues with the xml input is that formatting wide screen displays as if at .in 0 appears to be impossible, or at least not in evidence in any of the other inputs or outputs, which don't include such heavily indented lists of lists, and ending and restarting heavy indenting context appears ugly. -- Take care.

It is commonly mounted at /proc\&. Typically, it is mounted automatically by the system\&. .SS "Overview" .PP Underneath /proc, there are the following general groups of files and subdirectories: .PP /proc/[pid] subdirectories .RS 4 Each one of these subdirectories contains files and subdirectories exposing information about the process with the corresponding process id\&. .sp The /proc/[pid] subdirectories are visible when iterating through /proc with \fBreaddir\fR(2) (and thus are visible when one uses \fBls\fR(1) to view the contents of /proc)\&. .RE .PP /proc/self .RS 4 When a process accesses this magic symbolic link, it resolves to the process\*(Aqs own /proc/[pid] directory\&. .RE .PP /proc/[a\-z]* .RS 4 Various other files and subdirectories under /proc expose system\-wide information\&. .RE .PP All of the above are described in more detail below\&. .SS "Files and directories" .PP The following list provides details of many of the files and directories under the /proc hierarchy\&. .PP /proc/[pid] .RS 4 There is a numerical subdirectory for each running process; the subdirectory is named by the process id\&. Each /proc/[pid] subdirectory contains the pseudo\-files and directories described below\&. .sp The files inside each /proc/[pid] directory are normally owned by the effective user and effective group id of the process\&. .RE .PP /proc/[pid]/cmdline .RS 4 followed by null bytes (\*(Aq\e0\*(Aq)\&. .RE .PP /proc/[pid]/ctty .RS 4 This read\-only file holds the name of the console or control terminal device for the process, unless the process is detached from any terminal\&. In the latter case, there is only a newline in this file\&. .RE .PP /proc/[pid]/cwd .RS 4 This is a symbolic link to the current working directory of the process\&. To find out the current working directory of process 20, for instance, you can do this: .sp .if n \{\ .RS 4 .\} .nf $ \fBcd /proc/20/cwd; /bin/pwd\fR .fi .if n \{\ .RE .\} .sp Note that the \fIpwd\fR command is often a shell built\-in, and might not work properly\&. In \fBbash\fR(1), you may use \fBpwd\ \&\-P\fR\&. .RE .PP /proc/[pid]/environ .RS 4 This read\-only file contains the current environment that may have been changed by the currently executing program\&. The entries are separated by null bytes (\*(Aq\e0\*(Aq), and there may be a null byte at the end\&. Thus, to print out the environment of process 1, you would do: .sp .if n \{\ .RS 4 .\} .nf $ \fBcat \-A /proc/1/environ\fR .fi .if n \{\ .RE .\} .sp If, after an \fBexecve\fR(2), the process modifies its environment (e\&.g\&., by calling functions such as \fBputenv\fR(3) or modifying the \fBenviron\fR(7) variable directly), this file will reflect those changes\&. That may not be the case on other systems such as Linux\&. .RE .PP /proc/[pid]/exe .RS 4 This file is a symbolic link containing the actual pathname of the executed command\&. This symbolic link can be dereferenced normally; attempting to open it will open the executable\&. You can even type /proc/[pid]/exe to run another copy of the same executable that is being run by process [pid]\&. /proc/[pid]/exe is a pointer to the binary which was executed, and appears as a symbolic link\&. .RE .PP /proc/[pid]/exename .RS 4 This read\-only file contains the actual pathname of the executed command\&. .RE .PP /proc/[pid]/fd/ .RS 4 This is a subdirectory containing one entry for each file which the process has open, named by its file descriptor, and which is a symbolic link to the actual file\&. Thus, 0 is standard input, 1 standard output, 2 standard error, and so on\&. .sp For file descriptors for pipes and sockets, the entries will be symbolic links whose content is the file type with the inode\&. A \fBreadlink\fR(2) call on this file returns a string in the format: type:[inode] .sp For example, socket:[2248868] will be a socket and its inode is 2248868\&. .sp Programs that take a filename as a command\-line argument, but don\*(Aqt take input from standard input if no argument is supplied, and programs that write to a file named as a command\-line argument, but don\*(Aqt send their output to standard output if no argument is supplied, can nevertheless be made to use standard input or standard output by using /proc/[pid]/fd files as command\-line arguments\&. For example, assuming that \fB\-i\fR is the flag designating an input file and \fB\-o\fR is the flag designating an output file: .sp .if n \{\ .RS 4 .\} .nf $ \fBfoobar \-i /proc/self/fd/0 \-o /proc/self/fd/1 \&.\&.\&.\fR .fi .if n \{\ .RE .\} .sp and you have a working filter\&. .sp /proc/self/fd/N is approximately the same as /dev/fd/N in some Unix and Unix\-like systems\&. Most Linux \fBmakedev\fR scripts symbolically link /dev/fd to /proc/self/fd, in fact\&. .sp Most systems provide symbolic links /dev/stdin, /dev/stdout, and /dev/stderr, which respectively link to the files 0, 1, and 2 in /proc/self/fd\&. Thus the example command above could be written as: .sp .if n \{\ .RS 4 .\} .nf $ \fBfoobar \-i /dev/stdin \-o /dev/stdout \&.\&.\&.\fR .fi .if n \{\ .RE .\} .sp: .sp .if n \{\ .RS 4 .\} .nf $ \fBecho test | sudo \-u nobody cat\fR test $ \fBecho test | sudo \-u nobody cat /proc/self/fd/0\fR cat: /proc/self/fd/0: Permission denied .fi .if n \{\ .RE .\} .sp File descriptor 0 refers to the pipe created by the shell and owned by that shell\*(Aqs user, which is not nobody, so \fBcat\fR does not have permission to create a new file descriptor to read from that inode, even though it can still read from its existing file descriptor 0\&. .RE .PP /proc/[pid]/gid .RS 4 This read\-only file contains the primary group id for the process\&. .RE .PP /proc/[pid]/maps .RS 4 A file containing the currently mapped memory regions and their access permissions\&. See \fBmmap\fR(2) for some further information about memory mappings\&. .sp The format of the file is: .sp .if n \{\ .RS 4 .\} .nf \fIaddress perms offset dev inode pathname\fR 00010000\-00020000 rw\-s 00000000 0000:0000 0 [win heap 1 default shared] \&.\&.\&. 00080000\-00082000 rw\-p 00000000 0000:0000 0 [win heap 0 default grow] 00082000\-0009A000 ===p 00002000 0000:0000 0 [win heap 0 default grow] 000A0000\-000A1000 rw\-p 00000000 0000:0000 0 [win heap 2 grow] 000A1000\-000BA000 ===p 00001000 0000:0000 0 [win heap 2 grow] 000C0000\-000D9000 rw\-p 00000000 0000:0000 0 [win heap 0 default grow] 000D9000\-001C0000 ===p 00019000 0000:0000 0 [win heap 0 default grow] 00200000\-00377000 ===p 00000000 0000:0000 0 00377000\-00378000 rw\-p 00177000 0000:0000 0 [peb] 00378000\-0037A000 rw\-p 00178000 0000:0000 0 [teb (tid 8844)] \&.\&.\&. 00400000\-005F9000 ===p 00000000 0000:0000 0 [stack (tid 8884)] 005F9000\-005FC000 rw\-g 001F9000 0000:0000 0 [stack (tid 8884)] 005FC000\-00600000 rw\-p 001FC000 0000:0000 0 [stack (tid 8884)] 00600000\-006C7000 r\-\-s 00000000 EE45:4341 281474976741117 /proc/cygdrive/c/Windows/System32/locale\&.nls \&.\&.\&. 100400000\-100401000 r\-\-p 00000000 EE45:4341 281474978095037 /usr/bin/sh\&.exe 100401000\-100413000 r\-xp 00001000 EE45:4341 281474978095037 /usr/bin/sh\&.exe 100413000\-100414000 rw\-p 00013000 EE45:4341 281474978095037 /usr/bin/sh\&.exe \&.\&.\&. 180010000\-180020000 rw\-s 00000000 0000:0000 0 [procinfo] 180020000\-180029000 rw\-s 00000000 0000:0000 0 [cygwin\-user\-shared] 180030000\-18003C000 rw\-s 00000000 0000:0000 0 [cygwin\-shared] 180040000\-180041000 r\-\-p 00000000 EE45:4341 2251799814294868 /usr/bin/cygwin1\&.dll 180041000\-18022D000 r\-xp 00001000 EE45:4341 2251799814294868 /usr/bin/cygwin1\&.dll 18022D000\-180231000 rwxp 001ED000 EE45:4341 2251799814294868 /usr/bin/cygwin1\&.dll 180231000\-18026A000 rw\-p 001F1000 EE45:4341 2251799814294868 /usr/bin/cygwin1\&.dll \&.\&.\&. 800000000\-800090000 rw\-p 00000000 0000:0000 0 [heap] 800090000\-820000000 ===p 00090000 0000:0000 0 [heap] 7FF4FDEB0000\-7FF4FDEB5000 r\-\-s 00000000 0000:0000 0 7FF4FDEB5000\-7FF4FDFB0000 ===s 00005000 0000:0000 0 7FF4FDFB0000\-7FF5FDFD0000 ===p 00000000 0000:0000 0 \&.\&.\&. 7FFBEEAC0000\-7FFBEEAC1000 r\-\-p 00000000 EE45:4341 844424934724994 /proc/cygdrive/c/Windows/System32/kernel32\&.dll 7FFBEEAC1000\-7FFBEEB36000 r\-xp 00001000 EE45:4341 844424934724994 /proc/cygdrive/c/Windows/System32/kernel32\&.dll 7FFBEEB36000\-7FFBEEB68000 r\-\-p 00076000 EE45:4341 844424934724994 /proc/cygdrive/c/Windows/System32/kernel32\&.dll 7FFBEEB68000\-7FFBEEB6A000 rw\-p 000A8000 EE45:4341 844424934724994 /proc/cygdrive/c/Windows/System32/kernel32\&.dll 7FFBEEB6A000\-7FFBEEB72000 r\-\-p 000AA000 EE45:4341 844424934724994 /proc/cygdrive/c/Windows/System32/kernel32\&.dll \&.\&.\&. .fi .if n \{\ .RE .\} .sp The address field is the address space in the process that the mapping occupies\&.

[RPG TEMPLATE] Texture Cache
Just a small peice of the RPG template.. if the community would like i can post updates along the way. for thosenwho dont know what im talking about.
RPG Templateis just a easy import providing the core mechanics andlogic for rpg development. currently provides character attribute system, experience and leveling system. texture handling is about 1/2 way there and im currently building the item and inventory system.
doing this to try n help other that just want a fast poject to play with. if you have never constructed a rpg core structure before i can tell ou its no fast project.. lol if people would like regular updates just mention it in comments snd if there is any lol ill post. good day 🤓😉
Thought i would share this small class to cache game Textures. has came in handy for myself and my fellow developers. Hopfully it will help others in thiers.
Its pretty simply.. just creat a file named
assetsthen once an instance is created it will walk through all files and folders within nd get any files ending with
.pngor
.PNGit will then take the file name and split it at
%. first section will be used as the name used to call on the cached texture.
example:
`iron-ore%mining-stone.png` ⇢ cached[file.split('%')[0]] = scene.Texture("iron-ore%mining-stone.png") then to use the cached texture `ASSETS('iron-ore')` gives cached `_scene2.Texture object`
Hope this helps out anyone 🙃🤓😉
from os import (walk, getcwd, path) from scene import Texture class Assets: def __init__(self): self.cached = dict({}) self.CacheAssets() def __call__(self, name): return self.cached[name] def PrintCache(self): for k, v in self.cached.items(): print(f'{k}\n\t{v}\n{"*"*42}') def CacheAssets(self): id: int = 0 for r, d, f in walk(getcwd()+'/assets/'): for file in f: if file.endswith(".png") or file.endswith(".PNG"): id += 1 if '%' in file: name: str = file.split('%')[0] self.cached[name] = Texture(path.join(r, file)) else: self.cached[f'{id}'] = Texture(path.join(r, file)) ASSETS = Assets() ASSETS.PrintCache() | https://forum.omz-software.com/topic/6307/rpg-template-texture-cache | CC-MAIN-2021-31 | refinedweb | 352 | 68.26 |
The problem is that colon is not a valid character in the qname in an
xml element. The SVN DAV exposes the custom property as having a
namespace of "" and a qname of
the property name. What if the namespace for a custom property was
taken from the property instead? Why not use the namespace the property
is suggesting. For example, "cvs2svn:cvs-rev" would be broken out as
having a namespace of "cvs2svn" and a qname of "cvs-rev"? Colons are
permissible values inside the namespace, so if the property were
foo:bar:property it should be broken out as "foo:bar" and "property" for
the namespace and qname respectively.

Developing user interfaces with React tends to require effort and often it's done at the level of code. What if we could create user interfaces in the browser itself?
It's this question that we'll explore in this interview of Yang Zhang.
I'm a software engineer currently working full-time on Plasmic, which is a dream job for me - getting to build novel visual tools for users like myself. It's funny that I'm now deep in the front-end space because I came from a very backend-focused past life.
I used to study distributed database systems in my Ph.D. days, and I worked in applied machine learning at my last startup (Infer). I also used to work at big companies like Google and Microsoft, and now I'm all about tiny startups.
In any case, I did a lot of product engineering over the years, and so building surfaces that directly touch and empower end-users became my drug!
It's a tool for visually building components and full pages for any web app codebase!
You can use it merely as a no-code full-page builder that plugs into your codebase or use it to design low-level, complex, stateful components like autocompletes and date/time pickers.
One use case we're especially interested in is freeing up developers from requests from marketing, design, content teams, etc. These collaborators can instead directly create the things they want to see without being blocked by developers. Developers can, in turn, work on higher leverage things than pixel-pushing.
Plasmic is starting as a pretty technical tool since we've been focused on letting developers build low-level components. Still, we're actively making the service accessible to anyone. That way, it's as approachable as a Squarespace or Wix (but for your codebase). We're focused on making it scale well up and down this spectrum.
What you build in Plasmic can be consumed flexibly. You can generate actual React code into your codebase, or you can consume it like CMS content over an API - and more. The central point of Plasmic is about integrating into your arbitrary real-world codebase.
It's a browser-based tool, so it's easy to jump in and start creating things on any platform. What you're manipulating is the "real thing," the existing web platform (DOM/CSS/etc.), and not (say) vectors in WebGL or another medium, so what you see is what you ship.
You create your visual designs in Plasmic, and then:
All the logic/behavior (state bindings, event handlers, etc.) are all done from your code, the usual way. So Plasmic isn't trying to reinvent programming, make your code via a GUI, impose any particular routing/state management, etc.
In the case of codegen, what Plasmic spits out for you is a library of presentational components. They take care of rendering what you designed in the visual tool. If relevant, they provide a flexible interface that lets you wire up any props you want to any element within the component.
For instance, if you're making a simple "new post" form in Plasmic with an input and a button, you'll be provided the PlasmicNewPost component that handles all the styling/layout/tags for you, and you can wire up your real state and event handlers like so:
function NewPost({ onAdd, ...rest }: NewPostProps) { const [content, setContent] = useState(""); const history = useHistory(); return ( <PlasmicNewPost {...rest} postContent={{ autoFocus: true, value: content, onChange: (e) => { setContent(e.target.value); }, }} postButton={{ onClick: () => { onAdd( createPost({ content, createdAt: new Date() }) ); history.push("/"); }, }} /> ); }
It's a simple example. As things go much deeper, with components supporting different variations across different states, the composition of components, responsive design, and more.
There's also a new feature within Plasmic called Plume, which generates the behavior of components for certain well-known component types. So you can create an arbitrary design for (say) a Slider component and then have that fully working and accessible without writing any code – undifferentiated work that is time-consuming and tricky to do yourself.
You can trivially create a bespoke design system this way. Everything is powered by the excellent react-aria and react-stately libraries from Adobe. They go very deep on accessibility and take it further than most libraries I've seen.
I'll compare Plasmic with a few categories in terms of trade-offs.
These are drawing programs, great for exploratory mockups. Plasmic is for building the real thing. The trade-off is that Plasmic is more complicated since it lets you express all of the nuance and complexity that comes with production - maintainable abstractions, element semantics and accessibility, combinations of states, more complex layouts, and so on.
These are focused on static websites and are closed platforms. Plasmic focuses on flexible integration into arbitrary codebases and complex environments. The trade-off is that having full control of a closed platform is a faster way to build a simple end-to-end solution.
Plasmic is a better fit for complex projects with development teams or (for instance) JAMstack projects that unbundle into best-of-breed CMS, framework, hosting, CI, etc. Plasmic certainly isn't getting into the CI business, for example.
You can use Plasmic-as-a-CMS - invoke the client in your site's codebase, and from then on; your content teams can start using Plasmic immediately. We don't try to replace any existing CMSes, and we're looking to build integrations with CMSes and other data sources so that you can directly design with the real data in the tool. (And then you can still consume the output via an API, so it's a bit like layering CMSes.)
These are one-shot code generators that let you copy/paste into your codebase - as soon as you add your logic, you diverge from the original generated code. Plasmic lets you iterate on the design and consume that continuously from your codebase.
The trade-off is that one-shot generated code can look more familiar since you can generate what looks like clean, hand-written code. While Plasmic can also run in this mode and produce such code to generates, it's then consumed as a library of components.
Two reasons:
Plasmic is a very young project, so we have a ton of work to do.
But we are already starting to see production usage and fascinating use cases that we never anticipated, which is super exciting. The usage is across small and large companies. Our immediate focus is on fully supporting our budding community of developers and also designers.
I also mentioned above that we want to make the editor more streamlined and approachable to non-technical creators.
Another big project is code components - the ability to bring in your own existing React components into the editor.
But we want to cater our roadmap to the use cases that we see from our early adopters. So try out Plasmic and tell us what you would like to see! We would love to start a dialogue.
For Plasmic itself, building interfaces like this is just the start. We want to take this further and empower folks to create things that are more dynamic and more end-to-end. Our north star is about dramatically simplifying and accelerating many more facets of building digital products.
Focus on the users, experience, and product goals you are ultimately serving. It's is one of the extraordinary things about front-end development generally, and its proximity to the user. (This proximity is what drew me to focus on the front-end in my career!)
I mentioned above that Plasmic's Plume component system leverages react-aria and react-stately. I would encourage you to chat with Devon Govett. He is the madman behind these projects and the Parcel bundler!
We welcome you to check out Plasmic; we'd love to hear your thoughts!
Thanks for the interview, Yang! I feel there's a lot of potential in tools that bridge design with development and it looks like you are headed to an amazing direction.

Publishing Schema as Web Service in BizTalk 2004
Introduction
Buying and selling is the basic thing a company would do to run its business. A company buys raw material from its suppliers, refines it, and sells it to the customers.
If a company buys some material from its supplier, it places a purchase order and the supplier supplies the material based on the requirement in the purchase order. Almost all the companies prefer to use anelectronic PO these days because it saves effort, tracking, and money.
Scenario
The scenario is as follows:
- Supplier creates/gets a BizTalk schema for PO from buyer.
- Supplier publishes the schema as a Web service because Web services are loosely coupled and available on the Internet.
- Buyer consumes this Web service in his Application and creates a PO.
- Web service sends the PO to supplier's BizTalk via SOAP.
- BizTalk routes the PO to the appropriate application.
We will implement this scenario in five steps.
- Create and Deploy PO Schema
- Publish Schema as a Web service
- Create a subscriber for the PO in BizTalk
- Create a buyer application
- Test the scenario
Create and Deploy a PO Schema
Create a BizTalk project (WS_Schema in my solution) and add a new schema (PO.xsd) to it. I have promoted PONum node as a property to facilitate content-based routing. When we create a subscriber, we will use value of PONum to consume the PO.
Figure 1
Build and deploy the schema. After successful deployment, you should be able to see WS_Schema.dll in the BizTalk Explorer -> Assemblies section. See Figure 2.
Figure 2
Publish the Schema as a Web Service
Go to tools-> BizTalk Web Services Publishing Wizard and click Next. See Figure 3.
Figure 3
Select Publish schemas as Web services and click Next. See Figure 4.
Figure 4
Rename the Web service name as WS_Schema. Create a one way Web method and name it SubmitPO. Rename the message to PO. The Web service description should look like Figure 5.
Figure 5
Right click and select Select Schema Type. Select WS_Schema.dll from the bin directory of the WS_Schema project. Click Ok and Next. See Figure 6.
Figure 6
Specify target namespace, SOAP header, and so forth if required. In our scenario, we won't select anything to keep it simple. Click Next. See Figure 7.
Figure 7
Specify the project location as WS_Schema. Check anonymous access to allow IIS to execute this Eeb service without any authentication.
Check create BizTalk receive location to create a BizTalk receive location when we publish this Web service. Otherwise, you can create receive locations manually. Click Next. See Figure 8.
Figure 8
Click Create and finish to publish the Schema as a Web service. See Figure 9.
Figure 9
Click on Biztalk explorer -> Receive Ports to check whether the receive location is created or not. A receive location named WebService_WS_Schema/WS_Schema should be created. See Figure 10.
Figure 10
Edit this receive location. Change the receive pipeline to Microsoft.BizTalk.DefaultPipelines.XMLReceive. Select the Transport Type as SOAP and Address (URI) to /WS_Schema/WS_Schema.asmx (this is the schema we created as a Web service). See Figure 11.
Figure 11
Create a Subscriber for the PO in BizTalk
I will create a file send port as the subscriber of our PO. Create a new File Send Port and enter all the configurations.
Because I am using content-based routing here, I will specify a filter, WS_Schema.PONum=PO101, to fetch our PO and send it to a file location. See Figure 12.
Figure 12
Create a Buyer Application
We will create a VB.NET client application in our scenario; it will consume this Web service and send the PO to the supplier's BizTalk.
Create a Windows application. See Figure 13.
Figure 13
For simplicity, I will create a form and a button. Once the button is clicked, it will send the PO to the supplier.
Add a Web reference in the buyer project. Select the WS_Schema Web service and click add reference. See Figure 14.
Figure 14
It will add a WS_Schema Web reference to the buyer application. Add the following code to the Button Click event.
Private Sub txtSendPO_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) _ Handles txtSendPO.Click Dim objPO As New localhost.PO Dim objPOBilling As New localhost.POBillingAddress Dim objPOShipping As New localhost.POShippingAddress Dim objPOItems As New localhost.POItems Dim objPOItem As New localhost.POItemsItem Dim objPOSubmit As New localhost.WS_Schema objPO.PONum = "PO101" objPO.Date = "15-Jul-2004 objPOBilling.Street = "Corwell Lane" objPOBilling.City = "Uxbridge" objPOBilling.ZipCode = "UB8 3DE" objPO.BillingAddress = objPOBilling objPOShipping.Street = "Corwell Lane" objPOShipping.City = "Uxbridge" objPOShipping.ZipCode = "UB8 3DE" objPO.ShippingAddress = objPOShipping objPOItem.Code = "I101" objPOItem.Description = "Sony DVD Writer" objPOItem.Quantity = "20" objPOItem.Rate = "150" objPOItems.Item = objPOItem objPO.Items = objPOItems objPO.Total = "3000" objPOSubmit.SubmitPO(objPO) MsgBox("PO Sent to the Supplier") End Sub
Test the Scenario
Run the buyer application and click the SubmitPO button. It will create a PO with the values defined in our function and send it to the Supplier's BizTalk receive location. The receive location will pass the message to MessageBox and our subscriber will fetch the PO from MessageBox and send the XML to a file location.
Figure 15 shows the screen snapshot of Health and activity tracking before our subscriber consumed the PO.
Figure 15
Open the PO, delivered to a file location, and it will look like the following.
<?xml version="1.0" encoding="utf-8"?> <PO xmlns: <PONum xmlns="">PO101</PONum> <Date xmlns="">15-Jul-2004</Date> <ShippingAddress xmlns=""> <Street>Corwell Lane</Street> <City>Uxbridge</City> <ZipCode>UB8 3DE</ZipCode> </ShippingAddress> <BillingAddress xmlns=""> <Street>Corwell Lane</Street> <City>Uxbridge</City> <ZipCode>UB8 3DE</ZipCode> </BillingAddress> <Items xmlns=""> <Item> <Code>I101</Code> <Description>Sony DVD Writer</Description> <Rate>150</Rate> <Quantity>20</Quantity> </Item> </Items> <Total xmlns="">3000</Total> </PO>
Summary
We have seen a simple scenario to create and consume a Schema as a Web Service with minimum effort. It hardly takes a few minutes to create the entire scenario. Once I publish and consume the Web service in my buyer application, I need not use any XML DOM. All I need is to create an object of consumed Web Service and use it. The method automatically creates and submits the XML for you.

excellent article..ThanksReply | http://www.codeguru.com/cpp/i-n/internet/webservices/article.php/c7785/Publishing-Schema-as-Web-Service-in-BizTalk-2004.htm | CC-MAIN-2016-30 | refinedweb | 1,075 | 61.53 |
This tutorial is a sequel of our tutorial called “Capture image from the webcam”. Here we’ll add a new functionnality that let the user save the captured photo to his desktop. This example requires Flash Player 10.
1. Read and follow the steps of our previous tutorial “Capture image from the webcam” . We’ll begin this tutorial from the finished capatureWebcam.fla file of this previous tut.
2. Open the previous file. Create a new button on the stage, convert it to a movie clip and give it an instance name of save_mc.
3. In order to encode the captured image as a JPG, we’ll use the Adobe JPG Encoder that is available in the as3corelib. Visit to download the library. Unzip the file and inside the src folder grab the com folder. We’ll use what’s in the com/abode/images folder.
In order to save the image, we’ll use the Flash Player 10 FileReference API.
4. With the ‘actions’ layer selected open the actions panel. Add the following import statements :
import com.adobe.images.JPGEncoder; import flash.net.FileReference;
5. Next add a click event listener to the save button that will be handled by the saveImage function.
save_mc.buttonMode = true; save_mc.addEventListener(MouseEvent.CLICK,saveImage);
6. Inside the saveImage function declare a JGPEncoder and create a ByteArray of the bitmapData encoded as JPG.
Use the FileReference.save() method and pass in the ByteArray and the file name.++; }
7. Here’s the final code with the added code highlighted, test the movie to see it in action.
import flash.display.Bitmap; import flash.display.BitmapData; import com.adobe.images.JPGEncoder; import flash.net.FileReference;); save_mc.buttonMode = true; save_mc.addEventListener(MouseEvent.CLICK,saveImage); function captureImage(e:MouseEvent):void { bitmapData.draw(video); }++; }

how do I save image from webcam without using save dialogue box.
I want it like once i click save it should save image to specified location on disc shoild not pop up dialogue box for saving image.
how can we do this?
Hi can any one help me how to use the above sample to capture video instead of image….?
how do I import the jpgencoder into this thing?
Good.Thank you very much.
How would I go about automating the capture and adding a delay? I would like a movie clip to play a 3…2…1 countdown animation then take the capture automatically
can you help?!
thanks
Hi,
I tried your code..its working good..still i need a help..I want store the captured image in mysql database using asp.net..can anyone tell me how to do this
Hi,
Here you are saving an image in desktop rite..Instead of that i need to store it in database
Thank you very much. I struggled with the instructions in the Adobe site, and in other places, but your instructions are so clear, I’ve been able to use them to make a little web cam to run from inside our LMS so the students don’t have to access Web Toy etc. | http://www.riacodes.com/flash/captures-images-from-the-webcam-and-save-them-to-the-desktop/ | CC-MAIN-2016-07 | refinedweb | 526 | 68.47 |
Ever been on the features page and wondered what the Id of a Feature is?
The features page in the SharePoint UI is obviously a quick and easy way to activate and deactivate features. However, at first glance all you see is the title and description of the feature. You have no idea of knowing what the folder is let alone its Id. You’re out of luck on determining the feature folder name here, but you can get the Id pretty easily by viewing the source HTML of the page. I want to know the Id of the My Web Part feature, so I view the source and type in the name of the web part.
Looking at the source, we can quickly find what we need.
Take a look at the snippet of HTML above. This is where it displays the information for the title and description of my web part. Following that, you will see a non XHTML compliant div tag (really hope the HTML is better in the next version) with an id set to a GUID. As you might guess, that GUID is the Id of the Feature. It’s that simple. Just a quick tip today. Hope you find it useful.
I’ve been chasing this particular error for a little while and thought I would take the time to share my experience and how to resolve it. The scenario I had is I have a custom content type with several custom site columns. I generated the CAML for my content type and site columns using SPSource. When I clicked on the Create a new custom template button, I received the following error (or one similar).
propertySchema0.xsd#/schema/element[1][@name = 'properties']/complexType[1]/sequence[1]/element[1][@name = 'documentManagement']/complexType[1]/all[1]/element[1]
Reference to undeclared namespace prefix: 'ns1'.
As with all InfoPath errors, this is completely useless. After many attempts at trying to figure out this issue, I noticed that I could create a new Lookup Column and a new Content Type using the SharePoint UI and not receive this error. I then busted out the Imtech Fields Explorer and as far as I could tell all of the properties were just about the same. However, I noticed one difference in the SchemaXML property. My Field element did not have a SourceId but the column created through the UI did. It’s value was set to the Id of the web hosting the site column. I knew I couldn’t set it to that and so I remembered in the past I had always set the SourceId of the field element as seen below.
SourceID=””
This got me closer, the content types and site columns deployed correctly and the SchemaXML had a SourceID in it. However, when I tried to create a Document Information Panel this time, I got this new lovely error.
InfoPath has encountered an error. The operation failed.
Catastrophic failure
Once again, thanks InfoPath team for such useful error information. After further investigation, I discovered I needed to set the StaticName attribute as well. I simply set this to match the Name attribute I had and everything works now. It’s strange how the content type can work completely everywhere else, but in InfoPath it’s very picky. Here is what a complete working Field element might look like for you.
<Field Type="Text" DisplayName="MyField" Required="FALSE" MaxLength="255" Group="My Field Group" ID="{2E6858a5-6ae2-409f-8492-fa15c39821c8}" Name="MyField" SourceID="" StaticName="MyField" />
I mentioned above the issue I had was with a Lookup column but I quickly discovered that this was happening with all of my columns and had nothing to do with the lookup. SPSource has saved me a ton of time, but this is just another minor thing to look out with the tool. I logged an issue on CodePlex to see if we can get these two attributes added to the Site Column export. If you aren’t customizing Document Information Panels, then there is nothing to worry about with the exported CAML, but if you are be sure and add these two attributes.
According to Google Analytics, my introduction to SharePoint topics are by far the most popular topics on the site. I wanted to continue the trend on topics for new SharePoint developers, so I thought i would discuss debugging today. I’ve already discussed remote debugging in the past, but I thought it would be worth spending time on simple local debugging and provide some pictures. There may be several posts on this already, but I wanted something that I could refer to new developers I am working with.
In the ASP.NET world, you are used to working with everything on your own machine, setting a breakpoint, hitting F5 and you start debugging. We can do it the same way with SharePoint development right? No, of course not.
Before we start, lets assume you built a web part and want to debug it. If you aren’t familiar with how to build and deploy a web part, be sure and take a look at my post. In the scenario we are talking about, you are most likely developing inside a virtual machine and it is hosted on your other computer or somewhere else. This virtual machine has Visual Studio installed.
The way you debug varies slightly by whether or not you are deploying your binary to the GAC or to the bin folder. If you are deploying to the GAC, you do not need to worry about the .PDB file as Visual Studio will magically find it on its own when you start debugging. However, if you are deploying to the bin folder, you must copy the .PDB file from your bin\debug folder and copy it to the bin folder in inetpub for you web application.
At this point you are ready to start debugging. First, I’ll start by marking a breakpoint in my code.
As I mentioned earlier though, you can’t just hit F5 and call it good. Instead, you have to attach to the process running the web application your web part is on. This is the same process used when remote debugging. The difference is you don’t have to run the remote debugger and tell Visual Studio to connect to a remote server. to do this, go to the Debug menu and choose Attach to Process. You will then get a screen that looks like the one below.
The first thing you need to do is check the Show processes from all users and Show processes in all sessions checkbox. Don’t worry about the Transport, Qualifier, or Attach to options. The default options should work for you. If you happened to change them in the past, use the above screenshot, to get you back to where you need to be.
What we want to do is attach to the w3wp process that is running our web application. We know this is a w3wp.exe process, but if you look at the screenshot, you can see that we have three w3wp.exe processes in the list. How do you know which one to use? Well you have a number of options. You can use brute force and try each one and hit your web page and see if the breakpoint hits. That’s not really an ideal solution. If you’re smart when you set up your environment, you might have created separate accounts for each application pool. Notice above, how we have accounts named MOSS_AP_SSP, MOSS_AP_Portal, and MOSS_AP_CentralAdmin. Obviously, I am not debugging the SSP or Central Admin, so the MOSS_AP_Portal is the account to use in my case.
I get it though. That is an ideal situation and you may not be lucky enough to have everything running on separate accounts, so we need an alternative solution. Luckily, IIS has a script you can run which will tell you which worker process is running on which port. My web application is running on port 80, so if we identify a worker process for that port, we are in luck. In Windows Server 2003, you run cscript iisapp.vbs. In Windows Server 2008, you run appcmd list wps. Here is what it looks like in Windows Server 2008.
Now, I can confirm the process I want to attach to is 5980. I’ll click on this process in the list and we can start the debugging process. If all goes well, your breakpoint should look good in Visual Studio and it won’t have an explanation point. If it still has an explanation point, you may just need to hit a page on the site first to get Visual Studio to load the assemblies for debugging. Try hitting the page that has your web part and if everything works correctly, your break point should be hit and look like this.
As an ASP.NET developer, this may be different than what you are used to, but the steps involved really aren’t that bad. The code that I debugged in this example is the same code used in the How to Build and Deploy a Web Part post. If your breakpoint doesn’t get hit, I recommend recompiling and trying again. Verify that you have the right worker process and copy the .PDB file out if you are deploying to the bin folder.
A few months ago, I discussed how to use LINQ to XML to parse your elements.xml file to delete any files that you may have deployed on feature activation. Today I have decided to reuse this concept to delete any lists that I have created when I deactivate a feature? Now you may ask, “why would I want to delete a list when a feature is deactivated? I’ll lose all of my data in that list!” My answer is: Yes, of course you will, but sometimes when building a feature to deploy a list(s), you want to delete the list each time before you deploy a new version of it. During development this is a huge time saver. Right now, I am working on a feature that deploys four document libraries. This means I have to manually delete each one. That is a huge waste of time, but what is nice is that we can reuse the concept above with LINQ to XML and delete lists instead.
The code is quite similar. Have a look. We first, write some code to get the path to the elements.xml file. This code snippet assumes, it is always named Elements.xml. Maybe in the future, I will have it look in the feature.xml file, get all of the ElementManifest definitions and then delete whatever it finds in each file. For now though, we assume, you can change the path as needed.
public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
{
using (SPWeb currentSite = (SPWeb)properties.Feature.Parent)
{
string elementsPath = string.Format(@"{0}\FEATURES\{1}\Elements.xml", SPUtility.GetGenericSetupPath("Template"), properties.Definition.DisplayName);
DeleteLists(currentSite, elementsPath);
}
}
From here, it passes a reference to the current SPWeb and the path to the XML document. The path to the elements.xml file is used to populate an XDocument which we can then query with LINQ to XML.
private void DeleteLists(SPWeb currentSite, string elementsPath)
try
XDocument elementsXml = XDocument.Load(elementsPath);
XNamespace sharePointNamespace = "";
// get each URL to each list
var listInstances = from module in elementsXml.Root.Elements(sharePointNamespace + "ListInstance")
select new
{
ListUrl = (module.Attributes("Url").Any()) ? module.Attribute("Url").Value : null,
};
// iterate through each list and delete it
foreach (var listInstance in listInstances)
{
try
{
SPList currentList = currentSite.GetList(string.Format("{0}/{1}", currentSite.Url, listInstance.ListUrl));
currentList.Delete();
}
catch (System.IO.FileNotFoundException e)
// this exception is thrown if the list does not exist
}
// update the site
currentSite.Update();
catch
This code is quite similar to that used in my other post, however instead of looking for Module elements we are looking for ListInstance elements. It creates a list of those Urls to each list and iterates through them. For each list it finds, it deletes the list. I’ve written code in the past to manually delete lists, I create by name. That works fine, but the name of each list has to be maintained. Now, I just attach this to any feature I am working on and it deletes any list (or lists) that I throw at it. More than likely this isn’t something you want once you go to production, but it will save you a ton of time during development.).
It’s a known fact that MOSS 2007 Service Pack 2 hates me. Today, I was excited when I upgraded a server to SP2 and the configuration wizard didn’t fail. I was even more excited to see that my SSP and Central Administration still worked after the upgrade as well. Unfortunately, when I hit my main web application, I got a yellow screen with the following error.
COMException (0x80004005): Cannot complete this action.
Please try again.]
Microsoft.SharePoint.Library.SPRequestInternalClass) +0
Microsoft.SharePoint.Library.SPRequest) +215
That’s just great I figured. I checked the logs folder in the 12 hive and all I could find was an entry with the same text “Cannot complete this action”. Quite useless. After doing some searching, I encountered the following KB article. This articles applies to WSS2, but I noticed a lot of things mentioning the word impersonation, so I decided to have a look in my web.config. Sure enough, this server had impersonation turned off for some reason (no telling why). I set it back to true and the error went away.
I can’t continue to reiterate how much time SPSource can save you when it comes to exporting existing lists into usable features, but I found one minor thing to look out for when you are exporting lists. Usually, you can take just about whatever SPSource gives you and redeploy it without having to change a thing, however in the cases of lists you need to look out for the TemplateType attribute otherwise it can cause you problems. Take a look at the XML below from the elements file.
<Elements xmlns="">
<ListTemplate AllowDeletion="True" AllowEveryoneViewItems="False" BaseType="1" DisplayName="Concepts" Description="" EnableModeration="False" Hidden="False" OnQuickLaunch="True" Name="List1" Type="100" SecurityBits="11" Sequence="110" DocumentTemplate="101" VersioningEnabled="True" />
<ListInstance FeatureId="cac9f905-9380-4252-8307-d2cffb6f0c1f" Id="c5dd284f-fb59-44b9-bcfd-b4f779d9fd8d" TemplateType="100" Title="List1" Url="Lists/Lists1" />
<ListTemplate AllowDeletion="True" AllowEveryoneViewItems="False" BaseType="1" DisplayName="Regionals" Description="" EnableModeration="False" Hidden="False" OnQuickLaunch="True" Name="Regionals" Type="101" SecurityBits="11" Sequence="110" DocumentTemplate="101" VersioningEnabled="True" />
<ListInstance FeatureId="cac9f905-9380-4252-8307-d2cffb6f0c1f" Id="631657f0-b687-4b61-ad28-13ea1140cd21" TemplateType="101" Title="List2" Url="Lists/List2" />
As you can see I have a ListTemplate and ListElement element for two different lists (list1 and list2). If you look further you notice that the Type attribute on the ListTemplate elements is 100 and 101 respectively. The issue is that 100 is already reserved for a generic list and 101 is a document library so deploying this file can cause general weirdness in SharePoint. Here is the list of stock list template IDs in case you were curious.
As you may guess this is pretty easy to resolve. Just pick a new number that is not reserved for your Type. I believe the best practice recommends starting at 10000. After you change the Type attribute, be sure and change the TemplateType attribute of the ListInstance element to match it. That is all there is to it. If you haven’t checked out SPSource yet be sure to, the next time you need to export sites, lists, content types or site columns. It can save you a ton of time.
This week, I needed to deploy lookup columns to some of my lists and as usual I wanted to avoid writing code at all costs. As some of you may know, Kyle Kelin and I debate this topic often as he prefers a code approach. I figured it had to be possible with CAML, but many claimed it was not even possible. A few approaches showed up out there involving using code to modify the elements.xml file with your GUID, but that just wasn’t going to cut it for me. One popular post on the topic by Josh Gaffey, started me in the right direction, but there were a few hurdles I ran into as I was trying to implement it. It would create the list, show the content type, and site columns, but when I tried to create a new item, the lookup column was not there. The basic technique is that you specify the path to the list in the form of (Lists/MyListName) in the List attribute of the Field element in both your schema.xml file of your document library template as well as the definition of the site column. The first thing I learned here is that you cannot simply omit declaring site columns and a content type out and go with list level columns. It simply will not work (no idea why).
<Elements xmlns="">
<ContentType Name="Test" />
</Elements>
In my example, my content type was called Test. Create a separate feature folder for your list template and instance. Create another feature.xml and an .spsource file for the list which looks something like this. My list is also named Test in this case.
<ListTemplate Name="Test" />
SPSource does a good job when it exports my list definition and properly specifies the list using a path instead of a guid in my lookup column as shown below (from schema.xml).
<Field Type="Lookup" DisplayName="DocumentCategory" Required="FALSE" List="Lists/Categories" ShowField="Title" UnlimitedLengthInDocumentLibrary="FALSE" Group="My Group" ID="{9266e0fa-ae49-438c-acdc-73063684ac8f}" SourceID="{50b253e5-e90e-4781-8fce-cece417b185e}" StaticName="DocumentCategory" Name="DocumentCategory" Customization="" ColName="int1" RowOrdinal="0" />
We don’t actually have to change a thing in this file. What I did have to change is the List attribute of the file it generated for my site columns. As Josh’s post above stated, we have to change the List attribute from a GUID to the path of the list. His post also mentioned you might want to set the PrependId attribute but I have since learned that this is only used when you are using the LookupMulti type (although I can’t remember the source I got this from).
<Field Type="Lookup" DisplayName="DocumentCategory" Required="TRUE" List="Lists/Categories" ShowField="Title" UnlimitedLengthInDocumentLibrary="FALSE" Group="My Group" ID="{9266e0fa-ae49-438c-acdc-73063684ac8f}" Name="DocumentCategory" />
At this point you can deploy your site columns, content type, and then custom list (in that order) and if all goes well you will be able to create a new item of that content type with the lookup column functioning. One thing to note, if you get this wrong, your list will behave oddly. One thing I noticed is that it won’t turn on content types for the list when that happens. If this is happening go back and check your work. Another thing people mentioned is that the source list for the lookup column has to exist before you create the lookup column. This in fact is not true. It will work and it will display a drop down list for the lookup column, but it will be empty of course since the list does not exist.
Along the way I figured out a few other things. When I was trying to figure this out, I was trying to just create the content type and then manually add it to the list via the UI. Doesn’t work. If you try to add a content type with a lookup column defined in this way to an existing list, you will get the following error.)
The only way to get the content type associated with the list is via CAML when it is created. Another odd thing is that the lookup column never shows it is bound to the other list correctly. Here is what the source lookup column looked like.
Notice where it says Get information from, the name of the list is present. Here is what my copy of the list looks like.
Notice that the list name is not present. Strangely enough though, everything works fine in the copy. This one through me for a loop for a while because it didn’t seem like things weren’t working and as I mentioned above I couldn’t add the content type to a list (nor could I add the column to a content type).
As you can see there are few oddities about deploying lookup columns in this manner, but it does work. @SPKyle informed me he could have written code to do this hours ago, but I am quite happy that I can deploy things in this manner now.

Beginning C#: Basic I/O and Variables
WEBINAR: On-demand webcast
How to Boost Database Development Productivity on Linux, Docker, and Kubernetes with Microsoft SQL Server 2017 REGISTER >
Last month, we saw that you already had everything you needed on your computer that you needed to start writing C# programs. In this post, we're going to take a look at getting input from the user, and doing something with that input.
If you already have Visual Studio of some kind installed, feel free to use that. All of the programs you write will be "Console Mode" programs with nothing special. I'll go over installing Visual Studio in a couple of posts' time; for now, however, I will assume the use of the command line tools introduced last month, and a simple text editor such as Notepad or Notepad++ being used.
Outputting Text
When we left the last post, you'd created a simple program that used
Console.WriteLine("Hello World");
to write some text to the console.
C#, unlike many C-like programming languages, does not have a simple function or keyword for outputting text. Instead, we need to use a .NET library to output our text. It comes as no surprise that this library is called the 'Console' library, and, as can be seen above, it contains a method called 'WriteLine' that is used to output text.
The console library has a number of methods for dealing with simple console operations, 'WriteLine' outputs the text supplied, followed by a newline. Its counterpart 'Write' also outputs the supplied text, but unlike its predecessor, does not output a newline afterwards. 'Write' is used when you want to output multiple items of text on the same line.
As you did last post, create a simple text file called 'Hello2.cs' and make sure it contains the following code:
using System; namespace BlogConsole { class Program { static void Main(string[] args) { Console.Write("Hello "); Console.WriteLine("World"); } } }
When you compile and run this using CSC you should see the exact same output as in the previous version.
Figure 1: The same output is produced by using write and writeline
If you want to receive input, the console class also includes 'Read' and 'ReadLine' methods. Read reads the next available character from the console input stream whereas readline reads an entire line followed by a carriage return.
You'll also find that the console class has a method called 'ReadKey'. Readkey differs from read in that it captures a specific keypress. Readkey is used if you're looking for a single specific key, something like a function key, and it returns its data in a special type of data object called a 'KeyInfo' object. Read, like readline, waits for you to press Return to let it know you've entered the key you want to enter; but, unlike readline, it returns the pressed key by using its special numeric code.
Performing a Google search online for "ASCII code chart" will give you a full list of these codes. To get you started, capital A has a code of 65, B has 66, and so on.
I'll describe the difference in more detail in a future post. For now, however, know that there is a difference. If you were producing an onscreen menu, for example, ReadKey would be the appropriate method to use. If, however, you were trying to read a person's initial as part of an input form, read would be your weapon of choice.
Let's try another example. Create a new file called 'input1.cs' and, using your text editor, make sure it has the following code in it:
using System; namespace BlogConsole { class Program { static void Main(string[] args) { Console.WriteLine("Hello please enter your name"); string name = Console.ReadLine(); Console.WriteLine("pleased to meet you {0}", name); } } }
Compile it using 'csc input1.cs' and then run it. You should see the following:
Figure 2: Our program can now ask for our name
You'll notice that there's one new thing in the previous code:
string name = Console.ReadLine();
Data and Variables
Any program, large or small, needs to store data. Data is stored in something called a variable. You'll also find variables described as 'fields', 'properties', and 'objects' too, which is used depending on how you design your app. We'll get into this more in later posts once we start to cover object-orientated programming. For now, however, we'll use 'variables' to describe our data holders.
So what's in a variable? Well, in the line above we're telling the C# compiler that we're expecting a string and we want to refer to that variable as 'name'. A string is a sequence of characters that usually spells out a word or a sentence of text.
Strings of text that you add manually are surrounded by quote marks so that the compiler knows where the start and end are, something like the following:
string myText = "This is a string variable";
Variables can also hold numbers. If you wanted to store whole numbers only, you would use an 'int' variable type:
int myNumber = 10;
There are different types of number variables; if you wanted a standard decimal, you'd use the 'decimal' type; if you wanted floating point. you'd use 'float'. We'll cover the differences in number types in more detail later on; for now, we'll use 'int'.
The last simple variable type that I'll introduce you to is the 'boolean'. Booleans (or 'bools') are a very simple variable type that represents only true or false. Booleans are typically used as flags to indicate a yes or a no for something, and are declared as follows:
bool myChoice = false;
Variables are used to store the data you want to work with in your application. Let's now put this into practice.
Create a new file. Let's call this input2.cs, and make sure it has the following code in it.
using System; namespace BlogConsole { class Program { static void Main(string[] args) { Console.WriteLine("Hello please enter your name <Remember to press return afterwards>"); string name = Console.ReadLine(); Console.WriteLine("Hello please enter your age {0} <Remember to press return afterwards>", name); int age = int.Parse(Console.ReadLine()); Console.WriteLine("It must be nice to be {0} years old {1}", age, name); Console.WriteLine("Here's a menu for you, please choose wisely then press return."); Console.Write("a) "); // Code for lowercase a is 97 Console.WriteLine(" Choice A"); Console.Write("b) "); // Code for lowercase b is 98 Console.WriteLine(" Choice B"); Console.Write("c) "); // Code for lowercase c is 99 Console.WriteLine(" Choice C"); Console.Write("d) "); // Code for lowercase d is 100 Console.WriteLine(" Choice D"); int menuChoice = Console.Read(); if(menuChoice == 97) { Console.WriteLine("a is a mighty fine choice"); } if (menuChoice == 98) { Console.WriteLine("b is a superb choice"); } if (menuChoice == 99) { Console.WriteLine("c is the best choice"); } if (menuChoice == 100) { Console.WriteLine("d is the last choice"); } } } }
There are a couple of things in there that may be new to you, but don't worry about them at the moment. We'll get to them in future posts once we start to build up our knowledge of C#. For now, however, if everything compiles okay using CSC, you should see something like the following:
Figure 3: The output is more robust now
Before I leave you alone to play with the code, I'll show you one more trick that the console class has.
You can make your programs look a little bit nicer by using a variable, called 'ForegroundColor', inside the console library. By setting this to one of the variables available inside 'ConsoleColor', you can use different colors for different parts of your text.
Create a new file called coloredtext.cs and add the following code.
using System; namespace BlogConsole { class Program { static void Main(string[] args) { Console.ForegroundColor = ConsoleColor.Green; Console.WriteLine("This is green text"); Console.ForegroundColor = ConsoleColor.Red; Console.WriteLine("This is red text"); Console.ForegroundColor = ConsoleColor.White; } } }
Compile it using CSC and then run it. You should see something similar to the content of Figure 4.
Figure 4: The output text is coloured according to the code's specifications
By using colour statements in appropriate places, you can even have different parts of the same line appear in different colours.
Next month, we'll take a closer look at using variables, and I'll explain how and why you should convert them using methods such as parse to ensure that you get good data.
Until then, happy experimenting.

I'm making a specific number guessing game called "Bagels". I have most of the work done. But once I get to the actual game, I can only input one number for it to say if it is right or not. I need the program to keep allowing numbers to be inputted until it satisfies the do/while statement.
The input statements for the guessing are in the second do/while statement towards the bottom.
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Random;
public class Bagels {
public static void main(String[] args) {
BufferedReader input = new BufferedReader (new InputStreamReader (System.in));
System.out.println("Welcome to Bagels the Guessing Game!");
System.out.println("Press [Enter] to continue");
String start = new String ();
try {start = input.readLine();}
catch (IOException e) {};
String user1 = new String ();
String rulesornot = new String ();
System.out.println("To learn the rules, enter(1)");
System.out.println(" ");
System.out.println("To skip to the game, enter(2)");
try {rulesornot = input.readLine();}
catch (IOException e) {}
int rules;
rules = Integer.parseInt(rulesornot);
int userin1;
int userin2;
int userin3;
if (rules == 1) {
System.out.println("Rules: You are to guess a 3-digit number and you may not repeat a digit within an answer.");
System.out.println("If you guess correct on one number and it is in the correct spot that is \"Fermi\".");
System.out.println("If you guess correct on one number but it is not in the correct spot that is \"Pico\".");
System.out.println("If you don't guess any numbers correctly, than you will receive \"BAGELS\".");
System.out.println("Press [Enter] to continue");
String start2 = new String();// User has to press enter to continue to the game
try {start2 = input.readLine();}
catch (IOException e) {};
System.out.println("Begin guessing...");
}
else if((rules == 2) || (rules == 3))
System.out.println("Begin guessing...");
Random r = new Random();
int num;
int d1;
int d2;
int d3;
do{//generates a unique random 3 digit number
num = r.nextInt(900) + 100;
d3 = num % 10;
d2 = ((num - d3) / 10) % 10;
d1 = (num - d3 -(d2 * 10)) / 100;
}while (d1 == d2|| d1 == d3 || d2 == d3);
userin3 = num % 10;
userin2 = (num % 100) % 10;
userin1 = (num - d3 -(d2 * 10)) / 100;
int guessNumber;
do{
try {user1 = input.readLine();}//Input for guessing
catch (IOException e) {};
guessNumber = Integer.parseInt(user1);
if (d1 == userin1){
System.out.print("Fermi ");}
if (d2 == userin2){
System.out.print("Fermi ");}
if (d3 == userin3){
System.out.print("Fermi ");}
if (d1 == userin2) {
System.out.print("Pico ");}
if (d1 == userin3) {
System.out.print("Pico ");}
if (d2 == userin1){
System.out.print("Pico ");}
if (d2 == userin3){
System.out.print("Pico ");}
if (d3 == userin1){
System.out.print("Pico ");}
if (d3 == userin2){
System.out.print("Pico ");}
if ((d1 != userin1) && (d1 != userin2) && (d1 != userin3) && (d2 != userin1) && (d2 != userin2) && (d2 != userin3) && (d3 != userin1) && (d3 != userin2) && (d3 != userin3)){
System.out.println("BAGELS!");}
}while (num == guessNumber);
if (num == guessNumber){
System.out.println("You won!");}
}
}
Your while loop continues whilst the guess is equal to the hidden number, shouldn't this be whilst it isn't equal to the hidden number. You may want to think of adding a way to allow the user to exit from the game without having to guess the correct number.
Also you input the guess number but then don't do anything with it (other than in the while statement), shouldn't you be breaking into 3 separate digits to compare with the hidden number.
Posting code? Use code tags like this: [code]...Your code here...[/code]
I fixed the while loop but how do I make sure the game says the right stuff to the right inputted numbers?
how do I make sure the game says the right stuff to the right inputted numbers?
Is it printing the "wrong" stuff now?
Try debugging your program by printing out the values of all your variables so you can see how they are set and changed by the program.
For example:
System.out.println("d1=" + d1 + ", d2=" .... for the rest of the variables
Please copy the screen contents when you run the program and paste it here and add comments to it to explain what is wrong.

but how do I make sure the game says the right stuff to the right inputted numbers?
Read the last line of my previous reply.
If you have fixed this and still have a problem post your latest code.
I solved it on my own. Thanks. All I did wrong was mix the random digits and the user inputed digits together in my formulas.

I've been going through a relatively painless process of converting Tapestry from Maven to Gradle, and am thrilled with the results. My biggest stumbling point so far was Tapestry's use of Antlr3 for its property expression language.
The built-in support for Antlr only went as far as Antlr2. The Maven plugin I had been using understood Antlr3. After a bit of research and hacking, this is what I came up with as a solution for Tapestry:
description="Central module for Tapestry, containing all core services and components"
antlrSource = "src/main/antlr"
antlrOutput = "$buildDir/generated-sources/antlr"
configurations {
antlr3
}
sourceSets.main.java.srcDir antlrOutput
dependencies {
compile project(':tapestry-ioc')
compile project(':tapestry-json')
provided project(":tapestry-test")
provided "javax.servlet:servlet-api:$servletAPIVersion"
compile "commons-codec:commons-codec:1.3"
// Transitive will bring in the unwanted string template library as well
compile "org.antlr:antlr-runtime:3.3", { transitive = false }
// Antlr3 tool path used with the antlr3 task
antlr3 "org.antlr:antlr:3.3"
}
// This may spin out as a plugin once we've got the details down pat
task generateGrammarSource {
description = "Generates Java sources from Antlr3 grammars."
inputs.dir file(antlrSource)
outputs.dir file(antlrOutput)
} << {
mkdir(antlrOutput)
// Might have a problem here if the current directory has a space in its name
def grammars = fileTree(antlrSource).include("**/*.g")
ant.java(classname: 'org.antlr.Tool', fork: true, classpath: "${configurations.antlr3.asPath}") {
arg(line: "-o ${antlrOutput}/org/apache/tapestry5/internal/antlr")
arg(line: grammars.files.join(" "))
}
}
compileJava.dependsOn generateGrammarSource
The essence here is to create a configuration (a kind of class path) just for running the Antlr Tool class. The new task finds the grammar files and feeds them to the tool. We also thread the output of the tool as a search path for the main Java compilation task. Finally, we define the inputs and outputs for the task, so that Gradle can decide whether it is necessary to even run the task.
Part of the fun of Gradle is that it is still a Groovy script, so there's a familiar and uniform syntax to defining variables and doing other non-declarative things, such as building up the list of grammar files for the Tool.
As you might guess from some of the comments, this is something of a first pass; the Maven plugin was a bit better at assembling the list of input file names in such a way that the Antlr3 Tool class knew where to write the output Java source files properly; if Tapestry used a number of grammars in a number of different locations, the solution above would be insufficient. It also seems roundabout to use Ant to launch a Java application ... I didn't see an easier way (though I have no doubt its hidden inside the Gradle documentation).
My experience getting this working was mostly positive; there's a very large amount of documentation for Gradle that helped, though it can be a bit daunting, as the information you need is often scattered across a mix of the Gradle DSL reference, the User Guide, the Javadoc and the GroovyDoc. Too often, it feels like a solution is only understandable once finished, working backwards from some internal details of Gradle (such as which exact classes it chooses to instantiate in a given situation) back through the various interfaces, Java classes, and Groovy MetaObject extensions to those classes.
In fact, key parts of what I did ultimately accomplish were discovered through web searches, not in the documentation. But, that also means that the system works.
Of course, this is the pot calling the kettle black ... one criticism of Tapestry can be paraphrased as we can customize it to do anything, and in just a few lines of code, but it can take three days to figure out where those lines of code go.
At the end of the day, I'm much happier with Gradle; the build process is faster, the build scripts are tiny and much, much easier to maintain, and the feedback from the tool is excellent. There's still many more issues to work out ... mostly in terms of Apache and Maven infrastructure:
- Ensuring the Maven artifacts are created properly, with the right dependencies in the generated pom.xml
- Generating a Maven archetype using Gradle
- Generating JavaDoc and Tapestry component documentation with Gradle, along with a minimal amount of pages to link it together (akin to the Maven site plugin)
- Generating source and binary artifacts and getting everything uploaded to the Apache Nexus properly
Regardless, I think all of these things will come together in good time. I'm not going back, and dearly hope to never use Maven again!

* I think you may be able to get away without converting configurations.antlr3.asPath to a String.
* You can use the JavaExec task to eliminate the doLast block of your task (although you might still need a doFirst for the mkdir still).
* To address spaces in the path you should be able to change grammars.files.join(" ")) to grammars.files..collect { '"'+it+'"' }.join(" "))
* You could create a separate sourceSet for the generated code. i.e. sourceSets.generated.java.srcDir

Hi, i've just made a Fortune teller using java, my task now is to write the pseudo code for the code.
i'm a bit confused about how you do it, do i just write out the program but only with the statements in code?
I'm not asking for someone to do my work for me obviously, could i be shown an example of pseudo code taken from my code?
here is my code:
import java.util.Scanner;
public class NewClass {
public static void main(String[] args) {
String[] Outcome = new String[11];
Outcome[0] = "Idiot";
Outcome[1] = "You will find love today";
Outcome[2] = "You will be killed in a horrific way today";
Outcome[3] = "Someone will be watching you today";
Outcome[4] = "You will lose everything you own today";
Outcome[5] = "You will find something of value today";
Outcome[6] = "You will be attacked by a dog today";
Outcome[7] = "You will have luck on your side today";
Outcome[8] = "Unlucky day today";
Outcome[9] = "You will be promoted today";
Outcome[10] = "You will get fired today";
Scanner fortune = new Scanner(System.in);
System.out.println("Enter a number from 1-10");
int number = Integer.parseInt(fortune.nextLine());
int sum = number;
while (sum >= Outcome.length) {
sum = Outcome.length;
}
System.out.println("Your fortune: " + Outcome[sum]);
}
}

In this user guide, we will learn about pointers and multidimensional arrays. In our previous tutorial, we looked upon the general relationship of arrays with pointers and how to work with them. Follow the link given below to access that article:
We have already looked at pointers in the context of one-dimensional arrays. Now let move ahead and see how we can work with two-dimensional or even three-dimensional arrays using pointers.
Pointers with 1-D Arrays
To understand this concept better let us first briefly look at how to handle one dimensional array with pointers. First, we will declare a one dimensional array for e.g. an integer array num[] of size 5:
int num[5];
This means we are creating five different integer variables that are named num[0], num[1], num[2], num[3] and num[4] as one contiguous block of memory. This can be seen below as a section of the system’s memory.
The starting address of ‘num’ is ‘100.’ As we know byte in the system’s memory has an address and if we assume that an integer is stored in 4 bytes in a typical compiler then the block of four bytes at starting address 100 will be num[0]. Block of 4 bytes at starting address 104 will be num[1]. Next block of 4 bytes at starting address 108 will be num[2] and so on.
Lets store some values in this array for e.g:
int num[]={10,11,12,13,14};
Now let us look at the following statement:
int *ptr = num;
If we just use the variable name ‘num’ then the name of the array in an expression basically returns a pointer to the first element of the array. As ‘num’ is an array of integers so each element will also be an integer. Hence, ‘num’ returns a pointer to integer. After writing the above statement, we can now use pointer arithmetic and dereferencing to access all the elements in the array.
If we print the address stored in ‘ptr’ then the output will be 100.
printf("\n%d",ptr);
Dereferencing ‘ptr’ will give us the output ’10’.
printf("\n%d",*ptr);
If we print *(ptr+2), then the output will be 12. This is because we have an integer pointer adding 2. This will take us to the address of the next to next integer which will be 8 bytes ahead.
printf("\n%d",*(ptr+2));
Language gives us this flexibility that we can use the name of the array just like a pointer for all the dereferencing. So instead printing ‘ptr’ we can also do all of this with ‘num’. The output will still be the same.
printf("\n%d",num); printf("\n%d",*num); printf("\n%d",*(num+2));
In fact *(num+i) is same as num[i]. These are alternate syntax. Similarly, *(num+i) is same as &A(i). Both will give us the address of the i-th element in the array.
Thing to note: Even though we can use the name of the array just like pointer for all this dereferencing and arithmetic, it does not seem like a pointer variable. We can write the statement ptr= num; However, we can not write num =ptr; This will give us compilation errors.
Pointers with 2-D Arrays
Now let us look at how to handle pointers with two dimensional arrays. For example purposes, we will declare the following two dimensional array of integers named ‘num’.
int num[2][3]
We have created an array of array. ‘2’ is the number of rows and ‘3’ is the number of columns. In fact, we have created two one dimensional arrays consisting of three elements each. This time num[0] and num[1] are both one dimensional arrays of three integers each. A one dimensional array of three integers would be 12 bytes if each integer is 4 bytes in size. So, showing it in the system’s memory the first block of 12 bytes starting address 200 will be num[0] and the next block of 12 bytes starting address 212 will be num[1].
Point to Note: In the 2-D array, the address of a block is the address of the first byte in the block.
As we know that the name of the array returns a pointer to the first element in the array. This time each element is not an integer but instead each element is a one-dimensional array of three integers. So if we will write a statement like this:
int *ptr=num;
This will give us a compilation error. This is because ‘num’ will return a pointer to one dimensional array of three integers and not just a pointer to integer. The type of a pointer matters not when you have to read the address. It matters when you dereference or when you perform pointer arithmetic. It is very important to understand this.
We can define a pointer to a one-dimensional array of three integers in the following way.
int (*ptr)[3];
Equate ‘ptr’ with num:
int (*ptr)[3]=num;
Now we will print just ‘num’ which is the same as printing the address of num[0] through &num[0]. Thus, the output will be 200. However, if we will print *num which will be same as num[0] then num[0] is the variable name for the one dimensional array of three integers. So just using the name num[0] will return a pointer to the first integer in num[0]. This will be accessed as &num[0][0].
We will store values in our 2-D array as shown in the following statement.
int num[2][3]={{4,5,6},{14,24,34}};
You can view the individual integers in the memory blocks below.
Here you can see num[0] consists of three integer elements num[0][0] that is 4, num[0][1] that is 5 and num[0]num[2] that is 6. Likewise, num[1] also consists of three elements num[1][0] that is 12,num[1][1] that is 24 and num[1][2] that is 34.
Pointer Arithmetic and dereferencing with 2-D arrays
- Now if we print (num+1), the output will be 212. This is because num returns a pointer to one dimensional array of three integers. So if we will perform pointer arithmetic of adding plus 1 we are moving to the next 1-D array of three integers. Hence, we will be moving to address 200+size of 1-D array of 3 integers in bytes so that is why the output will be (200+12)=212. This is true because num+1 is equivalent to &num[1].
- Let us print *(num+1). Notice that we put an asterisk sign to dereference. Here the type of pointer holds significance. ‘num’ is a pointer to a 1-D array of three integers. Hence, (num+1) is also a pointer to 1-D array of 3 integers. When we will dereference this we will obtain the whole 1-D array of three integers with starting address 212. *(num+1) is the same as num[1]. This 1-D array num[1] which should return us the pointer to the first integer in num[1]. Thus, *(num+1) is basically the pointer to the integer at address 212. In other words, &num[1][0]. Hence the output will be again 212. Notice that all these expressions including *(num+1) or num[1] or &num[1][0] are returning an integer pointer and are equivalent statements.
- Now let us look at a bit harder one. What will be the output if we print *(num+1)+2?
As we saw above, *(num+1) returned us the integer pointer to the first integer in num[1] to the integer at address 212. Adding plus 2 here is performing pointer arithmetic because *(num+1) is a pointer to integer stored at address 212. Adding 2 means we are moving ahead to the next to next address of the integer thus skipping 8 bytes. We will end up at address (212+8)=220. *(num+1) in this expression can be written as num[1] as they are equivalent statements. Thus *(num+1)+2 is the same as num[1]+2 or &num[1][2]. All of these expressions are returning pointer to integer. In fact they are returning the the pointer corresponding to the element num[1][2].
- Lastly, let us find out the output if we print *(*num+1)
Whenever we encounter an expression with pointer arithmetic and dereferencing make sure to solve it in a series of steps to make it easier to obtain the output.
- Here ‘num’ is returning us the pointer to the 1-D array of size three. Then we are dereferencing this 1-D array of three integers. This will give us the 1-D array of integers so *num will give us num[0].
- Now num[0] is named for a 1-D array returns us the pointer to the first integer in the 1-D array so num[0] returns a pointer to integer. We will get a pointer to integer at address 200.
- Adding 1 to an integer pointer will take us 4 bytes ahead to the next integer. Thus, it will return us the pointer to the next integer. We will obtain a pointer to this integer at address 204. So we can say that *(num+1) is basically &num[0][1].
- With the final dereferencing *(&num[0][1]), we can get rid of the & operator so the overall expression now becomes num[0][1]. This is equal to ‘5’ in our case.
Note: For a 2-D array, num[i][j] where num is the name of our 2-D array i and j are indices, can be written as:
num[i][j] = *(num[i]+j)
= *(*(num+i)+j) where num[i] can be re-written as *(num+i)
Hence these three expressions are equivalent.
Pointers with 3-D Arrays
Now let us look at how to handle pointers with three dimensional arrays. For example purposes, we will declare the following three dimensional array of integers named ‘num’.
int num[3][2][2]
We have an array of 3x2x2. A three dimensional array is an array or collection of 2-D arrays. Here the first parameter ‘3’ is the block size or the number of 2-D arrays, the next parameter ‘2’ is the number of rows of the 2-D arrays and last parameter ‘2’ is the number of columns of the 2-D arrays. The following figure depicts ‘num’ in the system’s memory.
Here we have assumed that the starting address of ‘num’ is 400. The first sixteen bytes at starting address 400 is the first 2-D array which is num[0]. We are assuming that each integer will take 4 bytes so the first block is part of the first 2-D array. The next block of sixteen bytes with starting address 416 is num[1]. Likewise ,the next block of sixteen bytes with starting address 432 is num[2].
We will store values in our 3-D array as shown in the following statement.
int num[3][2][2]= { {{4,14},{20,31}}, //elements of block 1 {{30,6},{36,32}}, //elements of block 2 {{9,0},{19,67}} //elements of block 3 };
You can view the individual integers in the memory blocks below.
We can further break down the 2-D arrays into 1-D arrays. The first two integers in num[0] are part of the first 1-D array num[0][0]. The next two integers 20 and 31 in our case are part of num[0][1] and as follows as shown in the figure below:
The first integer in num[0][0] can be accessed as num[0][0][0]. We can access each integer in the following manner as shown below:
This time just using the array name ‘num’ will give us a pointer to a 2-D array of integers of size 2×2.
Pointer Arithmetic and dereferencing with 3-D arrays
The following statement declares a pointer to 2-D array of integers of size 2×2:
int (*ptr)[2][2]= num;
- The name of the pointer is ‘ptr’. Printing ‘prt’ or ‘num’ gives the output 400.
- Now if we will perform dereferencing and try to print *num then this will be the same as printing num[0]. As num[0] is a 2-D array so we will get a pointer the first element in num[0] which is accessed through &num[0][0]. All of these expressions return pointer to one dimensional array of integers of size 2. The address printed will be 800. Remember ‘num’ is a type pointer to 2-D array of 2×2 and dereferencing once gives us pointer to 1-D array of 2 integers. ‘num’ is returning us pointer to 2-D array of integers.
For ‘num’, num[i][j][k], where i, j and k are some indices, can be written as *(num[i][j]+k). We can write num[i][j] as *(num[i]+j) and num[i] as *(num+i) so the overall expression becomes:
num[i][j][k] = *(num[i][j]+k)
= *(*(num[i]+j)+k)
= *(*(*(num+i)+j)+k)
- Let us print *(num[0][1]+1) and see what the output will be. num[0][1] means we are going to the 1-D array that has two elements ’20’ and ’31’ in our case. Using the name num[0][1] means that we are obtaining the pointer to the first integer in this 1-D array. Now pointer to this integer ’20’ plus 1 means that we are moving ahead one integer that is ’31.’ Dereferencing this gives the output as ’31.’
Have a look at the section of the system’s memory to have a better understanding of the scenario:
Now let us find the output if we print *(num[1]+1). Here num[1] will return us a pointer to the 1-D array. The 1-D array in num[1] is the block containing the integers ’30’ and ‘6’ basically num[1][0]. Adding 1 to this is performing pointer arithmetic and thus moving ahead to the next 1-D array. This is the 1-D array which contains the integers ’36’ and ’32’ basically num[1][1]. Then we will dereference it to get the 1-D array from the pointer. As we used the name of the 1-D array we will get the pointer to the first element in the 1-D array. So we will get the pointer to the integer ’36’. Hence the output will be 424.
Have a look at the section of the system’s memory to have a better understanding of the scenario:
Example Code
Now let’s look at sample example codes for all the different concepts we have learned so far.
#include <stdio.h> int main() { int num[3][2][2]= { {{4,14},{20,31}}, {{30,6},{36,32}}, {{9,0},{19,67}} }; printf("%d %d %d %d",num,*num,num[0],&num[0][0]) ; }
Now let’s see the code output. After the compilation of the above code, you will get the following output.
As you may notice that all four expressions gave us the same output as was expected. All of these expressions return a pointer to a one-dimensional array of integers of size 2. They are equivalent statements.
Now let’s print the following statement:
printf("%d",*(num[0][0]+1)) ;
After the compilation, you will get the following output.
As this expression is equivalent to num[0][0][1] hence we will obtain the output ’14’.

When are destructors called for local variables
Non-static (or 'automatic' ) variables are 'destructed' automatically when they go out of scope. Scope is a farily complicated thing, and I'm not going to repeat the definition here. Roughly speaking the scope ends when you encounter the } around the declaration of the variable. See also the use of {} and how scope is defined in the for() statement.
Variables are destructed (by the compiler) by calling the appropriate destructor of their class. If the objects allocate memory (and hence the destructor should free that memory), this means that you recover the memory allocated.
class array { private: float *ptr; public: // constructor array(int n) { ptr = new float[n]; } // destructor ~array() { delete [] ptr; } } main() { // ... { array a(5); // allocates memory // do something } // here the array is destructed, and so the memory is freed //.... }
Use {} to keep things local
Use of the grouping construct {} enables you to declare variables local to that group. When leaving the group, all local variables are destructed. This has the advantage that the reader of the code knows (s)he shouldn't worry about these variables to understand the rest of the code.
In a way this can be understood as if every use of {} is like a function call (with local variables declared in the function). Of course, you don't have the overhead of stack manipulations and jumps involved in a proper function call.
// recommended usage void f(int a) { if(a==1) { myclassA Aobject; // here I do something with 'Aobject', and maybe 'b' } // Aobject does not exist here anymore
This tip is just an extension of the 'avoid global variables' credo.
As always, this can be disabused as in the following piece of code, where the outer variable 'a' is hidden by a local 'a', resulting in not very readable code.
[left]// not very readable code { int a=1; { // local variable hides outer 'a' int a; a = 2; assert (a==2); } // a is again the previous variable assert (a==1); }
Scope of variables declared in for()
The new ANSI C++ standard specifies that variables declared as in for(int i=1; ...) have a scope local to the for statement. Unfortunately, older compilers (for instance Visual C++ 5.0) use the older concept that the scope is the enclosing group. Below I list 2 possible problems, and their recommended solutions:
- you want to use the variable after the for() statement
[/left]
- you have to declare the variable outside of the for() statement.
[left]int i; for(i=1; i<5; i++) { /* do something */ } if (i==5) ...
- you want to have multiple for() loops with the same variables.
[/left]
Put the for statement in its own group. You could also declare the variable outside of the 'for', but it makes it slightly trickier for an optimising compiler (and a human) to know what you intend.
[left]{ for(i=1; i<5; i++) { /* do something */ } }
[/left]
When to use virtual members
Make a member 'virtual' if a derived class extends the functionality of a member of the base class, and this extended functionality has to be accessible:
- inside other member functions of the base class
- when using pointers that can point to either an object of the base class, or an object of the derived class.
Example: multi-dimensional arrays which are defined recursively in terms of a 1D array.
We wanted to have a 'grow' member that enlarged the outer dimension of the multidimensional array. At first sight, this is simply calling a general grow of the base class. However, 'grow' has to know the size of the new elements (which are again multidimensional arrays). So, we had to define in the derived class a new 'grow', which calls the base class 'grow' first, and then does more stuff.
At many points in the base class, 'grow' is called to adjust sizes. By making 'grow' virtual we avoid to having to rewrite these members for the derived class.
Caveat:
For members of the base class which use temporary objects of its own type, the base class 'grow' will be called. For instance:
[left]class array { ... virtual void grow(int new_size); array& operator +=( const array& a) { /* some definition using 'grow' */ } array operator +(const array& a1, const array& a2) { array a=a1; a += a2; // Warning, this will call array::grow, even if a1 is really from a derived type } }; [/left]
Thus, you should provide a member of the derived class for every member of the base class which uses temporary objects.
[indent]class multiarray : public array { ... virtual void grow(int new_size); multiarray operator +(const multiarray& a1, const multiarray& a2) { multiarray a=a1; a += a2; } }; [/indent]
- No Need to change existing code for incrementing functionalities in terms of inheritance
- Better than type field solution.
- and many more..

Happy going virtual!!!!!!!!!!!
Introduction
These tips are based mainly on ideas from the book Efficient C++ by Dov Bulka and David Mayhew. For a more thorough treatment of performance programming with C++, I highly recommend this book. This document, while presenting many of the same ideas in the book, does not go into as much detail as to why certain techniques are better than others. The book also provides code examples to illustrate many of the points presented here.
Constructors and Destructors
- The performance of constructors and destructors is often poor due to the fact that an object's constructor (destructor) may call the constructors (destructors) of member objects and parent objects. This can result in constructors (destructors) that take a long time to execute, especially with objects in complex hierarchies or objects that contain several member objects. As long as all of the computations are necessary, then there isn't really a way around this. As a programmer, you should at least be aware of this "silent execution". If all of the computations mentioned above are not necessary, then they should be avoided. This seems like an obvious statement, but you should be sure that the computations performed by the constructor that you are using is doing only what you need.
- Objects should be only created when they are used. A good technique is to put off object creation to the scope in which it is used. This prevents unnecessary constructors and destructors from being called.
- Using the initializer list functionality that C++ offers is very important for efficiency. All member objects that are not in the initializer list are by default created by the compiler using their respective default constructors. By calling an object's constructor in the initializer list, you avoid having to call an object's default constructor and the overhead from an assignment operator inside the constructor. Also, using the initializer list may reduce the number of temporaries needed to construct the object. See the Temporaries section for more information on this.
Virtual Functions
- Virtual functions negatively affect performance in 3 main ways:
- The constructor of an object containing virtual functions must initialize the vptr table, which is the table of pointers to its member functions.
- Virtual functions are called using pointer indirection, which results in a few extra instructions per method invocation as compared to a non-virtual method invocation.
- Virtual functions whose resolution is only known at run-time cannot be inlined. (For more on inlining, see the Inlining section.
- Templates can be used to avoid the overhead of virtual functions by using a templated class in place of inheritance. A templated class does not use the vptr table because the type of class is known at compile-time instead of having to be determined at run-time. Also, the non-virtual methods in a templated class can be inlined.
- The cost of using virtual functions is usually not a factor in calling methods that take a long time to execute since the call overhead is dominated by the method itself. In smaller methods, for example accessor methods, the cost of virtual functions is more important.
Return Value
Methods that must return an object usually have to create an object to return. Since constructing this object takes time, we want to avoid it if possible. There are several ways to accomplish this.
- Instead of returning an object, add another parameter to the method which allows the programmer to pass in the object in which the programmer wants the result stored. This way the method won't have to create an extra object. It will simply use the parameter passed to the method. This technique is called Return Value Optimization (RVO).
- Whether or not RVO will result in an actual optimization is up to the compiler. Different compilers handle this differently. One way to help the compiler is to use a computational constructor. A computational constructor can be used in place of a method that returns an object. The computational constructor takes the same parameters as the method to be optimized, but instead of returning an object based on the parameters, it initializes itself based on the values of the parameters.
Temporaries
Temporaries are objects that are "by-products" of a computation. They are not explicitly declared, and as their name implies, they are temporary. Still, you should know when the compiler is creating a temporary object because it is often possible to prevent this from happening.
- The most common place for temporaries to occur is in passing an object to a method by value. The formal argument is created on the stack. This can be prevented by using pass by address or pass by reference.
- Compilers may create a temporary object in assignment of an object. For example, a constructor that takes an int as an argument may be assigned an int. The compiler will create a temporary object using the int as the parameter and then call the assignment operator on the object. You can prevent the compiler from doing this behind your back by using the explicit keyword in the declaration of the constructor.
- When objects are returned by value, temporaries are often used. See the Return Value section for more on this.
- Temporaries can be avoided by using <op>= operators. For example, the code
a = b + c;
could be written as
a=b;
a+=c;.
Inlining
Inlining is one of the easiest optimizations to use in C++ and it can result in the most dramatic improvements in execution speed. The main thing to know when using inlining is when you should inline a method and when you shouldn't inline.
- There is always a trade-off between code size and execution speed when inlining. In general, small methods (for example, accessors) should be inlined and large methods should not be inlined.
- If you are not sure of whether or not a given method should be inlined, the best way to decide is to profile the code. That is, run test samples of the code, timing inlining and non-inlining versions.
- Excessive inlining can drastically increase code size, which can result in increased execution times because of a resulting lower cache hit rate.
- Watch out for inlined methods that make calls to other inlined methods. This can make the code size unexpectedly larger.
- Singleton methods, methods that are only called from one place in a program, are ideal for inlining. The code size does not get any bigger and execution speed only gets better.
- Using literal arguments with an inlined method allows the compiler to make significant optimizations. (This is, however, compiler dependent.)
- The compiler preprocessor can be used to implement conditional inlining. This is useful so that during testing the code is easier to debug. But for compiling production code, there are no changes to be made to the source code. This is implemented by using a preprocessor macro called INLINE. Inlined code is defined within #ifdef INLINE ... #endif code blocks. Similarly, non-inlined code is defined within #ifndef INLINE ... #endif code blocks. Then to compile using inlined code, you tell the compiler to treat INLINE as defined. (-DINLINE with g++)
- Sometimes it makes sense to inline a given method in some places, but to not inline in other places within the same program. This can be accomplished using a technique called selective inlining. The implementation of this technique is not very convenient. For each method that you want to selectively inline you have two methods, where on one has "inline_" prepended to the method name and is of course inlined. The method without the "inline_" prepended to its name simply calls the inlined version of the method.
- Recursive calls cannot be inlined, but there are two techniques to try to improve performance in the case of recursive methods:
- If the recursion is tail recursion, then the algorithm can be rewritten as an iterative algorithm, eliminating the overhead of method invocations.
- Recursive call unrolling basically allows the programmer to inline the first steps of recursion in a recursive algorithm. For example, for a recursive method print() we might do the following: print_unrolled() calls print1() which calls print2() which calls print3() which calls print(). All methods except print() are inlined. The number of recursive steps can be made as high as desired, depending on the application.
How about precalculated values. It saves a lot of time in slower machines during long iterations, does it not?
For eg:
x=23.45;
xinv=1/x;
and use xinv where its needed.
Also one can use precalculated trigonometrical functional values such as
float x=sin(x);
and so avoiding virtual functions while still allowing inheritance (does not work well all the time since only a limited amount of the behaviour is simulated though)...
well anyway if you are intrested take a look (it involves specifying the extending class as a template argument to the base class so the implemented class is known at compile time)...
Two guidelines from Thinking in C++ by Bruce Eckel:
- Avoid the preprocessor. Always use const for value substitution and inlines for macros.
- Avoid global variables. Always strive to put data inside classes. Global functions are more likely to occur naturally than global variables, although you may later discover that a global function may fit better as a static member of a class.
This book has 73 guidelines.

Not this again. This is not 1970!
Don't do this today or in the future. Use a temp variable.
An easy way to swap 2 variables without using another variable:
a=a+b; b=a-b; a=a-b;
it can't be used if operator+ and operator- arn't defined!!!
and you don't have to use another variable, in C++ standard, there is the STL. It is the strength of C++ because there are lots and lots of algorithms in it. For example, there is a sort that sorts your elements always in O(n log n) time, which is the fastest it can get (if you don't count counting sort). Therefore I use the it any time I can. There is also a templated function swap, that swaps any two elements that are of same type. So i think it is be easier and cleverer to type
swap(a, b); than to use your idea.
the best way to do this is to use the bits. The code would be:
inline string to_binary( const int &x ) { int t; string ret; if( x > 0 ) t = x; else t = -1 * x; for( int i = 0; i < 32; ++i ) if( t & ( 1 << i ) ) ret.push_back( '1' ); else ret.push_back( '0' ); reverse( ret.begin(), ret.end() ); ret.erase( 0, ret.find( '1' ) ); if( ret.size() == 0 ) return "0"; if( x < 0 ) return '-' + ret; return ret; }
An easy way to swap 2 variables without using another variable:
a=a+b; b=a-b; a=a-b;
Easy way? I don't know, but sure it is inefficient (except if the optimizer is really good).
There *are* temporary variables if from an ISO standard point-of-view.
And, this algorithm can only be useful if (assuming an optimizer as good as Turbo C++ 1.0 optimizer or better, knowing that it is a very old compiler, with an obsolete optimizer):
- Both a and b are in a register (otherwise, I don't know any architecture where the temporary would be avoided)
- AND There is no builtin XCHG instruction at the assembly level (false for x86 and PowerPC)
- AND The CPU lacks register (in that case, it is very probable that the CPU has a XCHG instruction).
And, in that case, you may, ocasionally (rarely) gain little performance... In all other cases, you just can pray that the optimizer will understand your bad code, and implement it in a correct way.
Most compilers I know produce bad code for that.
If you use a 25 years old compiler, with a very very bad optimizer, it might also be possible that this compiler lacks register variables...
In that case, the following code:
a-=b; b-=a; a-=b;
Will produce something like (on x86-16, yep I can't imagine any such bad optimizer on x86-32):
mov ax, [bp-8] ; timings on a k6-2 CPU (1) sub ax, [bp-4] ; 3 mov [bp-8],ax ; 4 CPU cycles mov ax,[bp-4] sub ax,[bp-8] mob [bp-4],ax mov ax, [bp-8] sub ax, [bp-4] mov [bp-8],ax ;11.5 CPU cycle (i.e. the last one might be paired with the next instruction)
Note : If the optimizer is even more bad than what I described, the generated code might even be worst.
And, your code (which has temporaries), on the same compiler might be twice as slow...
The classical
int c; c=b; b=a; a=c;
Will produce something like:
mov ax,[bp-4] mov [bp-12],ax mov ax,[bp-8] mov [bp-4],ax mov ax,[bp-12] mov [bp-8],ax ; 5.5 CPU cycles (on a K6-2 CPU)
Note : I don't think that the compiler can generate worst code, even if there is no optimizer.
So, my point is that your code is *always* a bad idea.
This algorithm might only be used in some very special contexts, only on weird architectures (I don't know any such architecture, but it probably exists or existed), and at assembly level only!
Please, read my posts (SuperKoko) on these two threads (of another forum):
Also, remember that std::swap can be assumed as being optimal on your architecture : The compiler is allowed to do specific optimizations on it.
When you want to pass a constant variable, pass it by reference to save memory.
Example:
int example (const int value); // Uses more memory than
int example (const int &value); // this one
That's the opposite!
Using const references is a good idea for large objects (say, 16 bytes and more).
For very small objects (smaller than a pointer), if you're lucky, you'll not loose performance.
But it is quite probable that the compiler will generate more code, slower code, and use more stack memory (if the argument is not a lvalue).
And, moreover, it is very hard for the compiler to optimize the const-reference thing when the function is used across translation units boundaries (at least, for most compilers), because it must respect a calling convention, and can't know whether the function, internally, gets the address of the const reference.
In that case, the compiler can't replace such const-reference by a simple value.
Please read my posts on these two threads:
Valid, albeit ancient, advice -- much like the XOR swap.
It's one of those things that language implementers knew about ages ago, and should be done by the compiler automagically (or it may take some optimization option).
Bottom line: don't do this unless your compiler sucks. Write code to multiply by 4 like this
num*=4 . Obfuscating it as
num<<=2 will make your code look strangeto newbies, and it will look like a newbish hack to old timers (both making what you write a little suspect).
And don't forget that right-shifting signed values is implementation defined!
A few more I find useful...
1. Replace switch-case/if-else with array-indexing:
switch ( queue ) { case 0 : letter = 'W'; break; case 1 : letter = 'S'; break; case 2 : letter = 'U'; break; } //or maybe if ( queue == 0 ) letter = 'W'; else if ( queue == 1 ) letter = 'S'; else letter = 'U'; //A quicker method is to simply use the value as an //index into a character array, eg. static char *classes="WSU"; letter = classes[queue];
2. I'm sure most ppl know this but writing as it's not already mentioned in this topic so far. Use unsigned int stored in registers for loop variables.
Reasons
1. unsigned int arithmatic is faster than signed int.
2. registers are registers ! They're simply faster than memory access.
for( register unsigned int loop_variable = 0; loop_variable <=100000; i++ ) { /*do your stuff*/ }*/}
4, Optimizing very small loops using switch-case.
When you know that the range of loop variable's value is
pretty small avoid the loop altogether.
//unoptimized code for( int i = some_small_positive_int; i--; ) {/*do your stuff with i*/} //optimized based on the assumption that some_small_positive_int can only be from 1 to 7. switch( i ) { case 7 : /*do your stuff with i*/ i++; case 6 : /*do your stuff with i*/ i++; case 5 : /*do your stuff with i*/ i++; case 4 : /*do your stuff with i*/ i++; case 3 : /*do your stuff with i*/ i++; case 2 : /*do your stuff with i*/ i++; case 1 : /*do your stuff with i*/ }*/}
Except if your description is true, you'd be better off using
i = 30; while (i--) { /*do your stuff*/ }
5. Another way of optimizing loops is to unroll it:
//unoptimized loop int loop_count = 50000; /* could be anything */ for( int j = 0; j < loop_count; j++ ) printf("process(%d)\n", j); //optimized one static int BLOCKSIZE = 8 ; /* The loop_count may not be divisible by BLOCKSIZE, * go as near as we can first, then tidy up. */ int i = 0; int blocklimit = (loop_count /; } //we already know how to optimize small loops. switch( loop_count -); }

KashAI>> TRUE. So I hope that anyone able enough to understand this won't blindly copy my code.
> 1. unsigned int arithmatic is faster than signed int.
Where's your evidence?
KashAI>> I was afraid someone will ask. :). Anyway, simple answer is I don't know.
But here is what I know:
1. In VS 6.0 (on Intel H/W) a simple for loop with loop variable being unsigned is about 2 seconds faster than when loop variable is signed int. (looped some 100K and 500K times to print the value of loop variable)
2. In most cases one can see that there are seperate assemply instructions for signed and unsigned arithmetic. Which at least indicates a difference in performance.
3. Number of flags applicable (CF=carry-over-flag, SG=sign-flag, OF=overflow-flag) to signed and unsigned instructions' execution are different.
4. I'm vaguely remember an instruction called SBB (substract using borrow) which, if i'm not wrong, is only applicable to signed arithmetic.
And use of it is in case where the requested substraction of 2 signed numbers can not be completed with a single instruction due to register size.
> 2. registers are registers ! They're simply faster than memory access.
True, but any decent compiler nowadays is far more capable of deciding which variables would be best placed in registers.
KashAI>> So if I understand it right what I've written is correct, but not neccesarry.
>.
KashAI>> So in short, should one NOT optimize it this way? May be you could add some practical numbers for the benefit of readers which will help them in deciding whether to use this optimization or not?
E.g. "in 80% of cases cache is optimised in favour of incremental access" OR
"Now-a-days most machines support ".
KashAI>> Now that is useful info. Just checked and found that VS 6.0 and Sun Workshop 6.0 also support lopp unrolling.
Sorry forgot one more thing regarding "1. unsigned int arithmatic is faster than signed int.
Where's your evidence?"
See.
2. I'm sure most ppl know this but writing as it's not already mentioned in this topic so far. Use unsigned int stored in registers for loop variables.
Reasons
2. registers are registers ! They're simply faster than memory access.
Most compilers ignore the "register" keyword, because their optimzations are far more advanced than back in the time, where a variable had only one storage in its life...
But, the register keyword can reduce performances on some compilers, because they interpret it as a strong request, from the programmer, to use a register for storage of the variable, which condemns one register.
Even on very old compilers where the register keyword was a useful hint, it would have been utterly stupid to use the register keyword everywhere, as it would be as slow, or slower, than using no keyword at all, because the compiler would not be better than using its default "guessing" algorithm.
The register keyword should be used only at places, where you want to give a hint to the compiler, that THIS variable needs to be accessed faster than other ones, even if it reduces performances of other variables.
1. unsigned int arithmatic is faster than signed int.
Ridiculous.
On two's complement machines, additions, substractions and multiplications have identical performances as signed or unsigned, since this is exactly the same operation.
For comparisons, the performances are identical on x86 architectures, since the same operation is used for all comparisons (cmp).
On all other architectures, there is absolutely nothing that would add a performance penalty on signed comparisons, because integer comparisons require only very very few transitors... The comparison itself, cannot require more than one CPU cycle.
For integer division, signed integer division was a bit slower than unsigned integer division on old CPU.
But, integer divisions are very rarely time critical, because division is not a very much used operation.
3. Optimizing the breaking conditions in for loops. If you know that the loop variable's range is from 0 to some +ve number AND it doesn't matter which way you traverse while looping, you can optimize the loop like this:
Assuming that the compiler doesn't optimize it for you.
GCC 3.4.5 (-O2) for i386, is clever enough to optimize the first loop with a decrementation operation.
This is because, forward loops are very common, and GCC has specific optimizations for this type of code.
On the other hand, GCC 3.4.5 is not clever enough to produce good code for your "manually optimized" loop.
for( int i = 0; i <= 30; i++ );
Produces this assembly code (MinGW 3.4.5 for Win32 -O2):
0x401300 : dec eax 0x401301 : jns 0x401300
But:
for( int i = 30; i--; );
Produces:
0x401300 : dec eax 0x401301 : cmp eax,0xffffffff 0x401304 : jne 0x401300
Why this pessimization?
First, the following code:
0x401300 : dec eax 0x401301 : js 0x401300
Would immediately stop if eax is negative... But, the conditional expression is about the inequality with zero!
The compiler could have seen that all the values of i will be in range [0,30), but GCC is not clever enough to understand that, because you wrote a weird loop.
A good code, benefiting from the fact that "dec eax" sets the zf and sf flags, would require that you stop when i reaches zero, not -1.
Your code confuses the compiler, and is a pessimization.
So, don't do that!
Note:
for( int i = 31; --i; );
Generates the right code:
0x401300 : dec eax 0x401301 : jns 0x401300
With MinGW 3.4.5. I don't claim that it's ok. It may be a pessimization with another compiler.
4, Optimizing very small loops using switch-case.
When you know that the range of loop variable's value is
pretty small avoid the loop altogether.
Or... activate the -funroll-loops option (or your compiler equivalent), which is less error prone.
Also, you should notice that, this should only be used on the most critical code, as it greatly increases the code size, which can have a serious performance penalty.
5. Another way of optimizing loops is to unroll it:
Knowing that printf is so slow that the loop code itself is negligible...
I benchmarked the two programs, using NUL as the standard output.
There is no sensible speed difference.
Both require 3900 milliseconds to execute on my computer.
A revelant piece of code of the two things:
; without manual loop unrolling ; Assume a K6-2 CPU 0x401323 <main+67>: inc ebx 0x401324 <main+68>: push 0x403000 ;1 0x401329 <main+73>: call 0x4018a0 <printf> 0x40132e <main+78>: add esp,0x10 0x401331 <main+81>: cmp ebx,0xc350 ;1 0x401337 <main+87>: jl 0x401320 <main+64> ; 3 ; -> 3 CPU cycles + approximatively 39600 CPU cycles for the printf call (if the output stream is the NUL device).
; with manual loop unrolling 0x40134d <main+109>: pop eax 0x40134e <main+110>: lea eax,[ebx+1] ;1 0x401351 <main+113>: pop edx ;2 0x401352 <main+114>: push eax ;3 0x401353 <main+115>: push 0x403000 ;4 0x401358 <main+120>: call 0x4019c0 <printf> ; -> 4 CPU cycles + approximatively 39600 CPU cycles for the printf call.
So, your "optimization", approximatively reduce performances by 0.0025%.
Which is negligible..
You should not do that before checking whether printf is slower or faster than cout.
This is very highly compiler dependent.
For example, Borland C++ 5.0 is faster for cout than for printf.
Check my answer on this thread:
And, don't forget that micro-optimizations are the ennemy of real optimizations.
A performance tip that has served me well with C++, C#, Java, VB, and scripting languages is counting backwards. When using a comparison in a loop (presumably for termination purposes), if possible, count down to zero instead of up to a non-zero value.
Since every machine language in existence has "compare to zero" operators, smart compilers can utilize this efficiency.
Normally, the compiler saves the comparison value in memory and then accesses it indirectly for each loop. However, many compilers will recognize the comparison to zero and optimize it with a single machine language command, bne, bge, etc..
In complex, nested loops, the optimization can be amazing. The main down fall I've observed is compiler consistency. I have not observed .NET's IL doing this and it doesn't always do this when going native.

cAudio 2.0.0 Release!
on: February 22, 2010, 12:16:36 am
The next version of cAudio has been released. cAudio is an advanced C++ wrapper around OpenAL that makes it easier to put 3D audio into your games and other applications. This version includes some major API rework, many new features, and a brand new plugin system. It also includes much better API documentation to make it easier to incorporate into your projects. Also included is a large number of bug fixes.
New Features:
All OpenAL "Effects Extension" audio effects and filters are now supported by the engine. This means you can easily drop in effects like EAX Reverberation, Distortion, Flanger into your application and attach them to any number of audio sources in your world. Use them to create the illusion of large caverns, or tiny hallways, or virtually any other environment.
Audio Capture is now supported. Stream audio from a microphone, line in, or virtually any other capture device into your application using a simple interface.
cAudio now uses multiple threads internally to handle loading and playback of sounds (as well as background capture of audio). cAudio is also now thread safe.
Ability for users to override where cAudio gets its file data for playing sources. Instead of only being able to get files from the hard drive or from a memory location in your program, you can now supply an interface for cAudio to use. Thus you can stream data into cAudio from virtually any location, whether that is a zip archive, TCP/IP stream, or Ogre/Irrlicht resource system.
New logging system with user definable log receivers, allowing the developer to have full control of where the log messages go. cAudio also provides default console and html file log receivers.
New Event system. cAudio can now automatically call functions in your code when certain events happen in the engine. For example, you can get an event when a source stops playback.
New Plugin System. This system supports both dynamically linked libraries and static plugin definitions. Plugins have full control of the engine and can be used to add new audio decoders, log receivers, data sources, and act upon events in the engine.
New MP3 Decoder plugin. Many of our users have been asking for mp3 playback capability and now it is offered as an official plugin.
New EAX Legacy Preset plugin. Offers all of the classic EAX Legacy presets for EAX Reverberation effects. This makes it easy to drop in an reverberation effect that sounds close to the environment you are modeling and then tweak it later.
Several new examples to show off the new features of the engine.
Advanced Memory Manager
Major changes:
The Audio Playback Manager is no longer a singleton. It must be created using the createAudioManager() API function. This is to support the possibility of multiple playback managers someday in the future, though this feature is not currently supported.
A 3D vector class is now provided by the engine and is required by several API functions. This means no more entering 3 floats into a function constantly.
Several components of the library are now reference counted. This is to ease issues when the user may want to retain an object even after they remove it from the engine, as well as make deletion of unused objects easier internally.
A cross platform sleep function is included for example usage.
The Audio source class has been renamed from cAudio to cAudioSource.
Added a global include file "cAudio.h" that will automatically include all the major headers in the engine.
We also have a new web site, SourceForge project, and forums.

API Documentation:
SVN Trunk:
Windows (MSVC 2008 and Codeblocks) and Linux (Make and Codeblocks) SDK downloads are available.

cAudio 1.7.1 c++ Audio Engine
on: May 20, 2009, 09:34:09 pm
cAudio was created to be a good alternative to fmod,bass, and irrklang.
Example code cAudio:
Code:
//Basic 2d audio
#include <iostream>
#include "../../include/IAudioManager.h"
#include "../../include/IAudio.h"
using namespace std;
int main(int argc, char* argv[])
{
cout <<"cAudio 1.7.1 Tutorial 1: 2DSound\n";
cAudio::IAudioManager* manager = cAudio::getAudioManager();
manager->init(argc,argv);
cAudio::IAudio* mysound = manager->createFromFile("bling","../../bin/bling.ogg",true);
mysound->play2d(true);
while(mysound->playing()){
manager->update();
}
manager->release();
manager->shutDown();
return 0;
}
The cAudio Engine is a c++ wrapper around openal to allow you to get sound and music into your games easily.
current version 1.7.1
The main reason behind making cAudio was there wasn't a hole lot of choices for getting sound into your game. Basically there was audiere, fmod, bass, irrKlang,and SDL mixer. Also there was openal which cAudio is built on. The only problem with using openal is its.

Why didn't anyone use this obvious variant?
proc lambda {p b} {
set name [list lambda $p $b]
if {[info procs $name] eq ""} {
proc $name $p $b
}
return $name
}
General lambda use cases work well:
% [lambda {s1 s2} {puts "s1=$s1 s2=$s2"}] asd cvb
s1=asd s2=cvb
% set aaa [lambda {s1 s2} {puts "s1=$s1 s2=$s2"}]
lambda {s1 s2} {puts "s1=$s1 s2=$s2"}
% $aaa q w
s1=q s2=w
Something wrong?
Personally I think the [apply] method that we now have in 8.5 is the
way to go. Lambdas are after all merely values. So there is no reason
to treat a lambda as anything other than a string until you want to
use it as a function. So:
# In tcl a lambda is simply a string:
set aaa {{s1 s2} {puts "s1=$s1 s2=$s2"}}
# Only when you want to use it does it need special treatment:
apply $aaa q w..... ;-)

No.. just say $::do_something, $::print. Or if you use [interp alias]
like in the Wiki page mentioned, you have global names back :^)
We WILL have ;) there's still no release.
At least, I could use this lambda for backward compatibility.
Tcl 8.4 is actual standard now.

Procs are compiled only once.
And what about apply-lambda?
No ;)
There are arrays
AFAIK they get their bytecodes cached in the internal rep, so they
only get compiled once like procs.
Michael
Correct.
Donal.
There's no reason why you couldn't implement [apply] in 8.4. It's not
a syntax extension, it's just a special kind of [eval]. Here's one
possible implementation:
proc apply {lambda args} {
# Sanity check:
if {[llength $lambda] != 2} {
error "malformed lambda"
}
foreach {vars script} $lambda break
# Process the args:
if {[lindex $vars end] == "args"} {
set vars [lrange $vars 0 end-1]
set vals [lrange $args 0 [expr {[llength $vars]-1}]]
set args [lrange $args [llength $vars] end]
if {[llength $args] < [llength $vars]} {
error "wrong # of args"
}
} else {
set vals [lrange $args 0 [expr {[llength $vars]-1}]]
if {[llength $args] != [llength $vars]} {
error "wrong # of args"
}
}
# Done preprocessing arguments,
# now do the eval:
eval [string map [list \
%VARS% $vars \
%VALS% $vals \
%ARGS% $args \
%SCRIPT% $script \
] {
if {[llength {%VARS%}]} {
foreach {%VARS%} {%VALS%} break
}
%SCRIPT%
}]
}
In fact, I don't see anything from the code above that requires Tcl
version > 7.3. So in theory we could have had lambdas way back in Tcl
7. The problem is not that Tcl didn't (or doesn't) support lambdas.
The problem is lack of imagination of how to implement lambdas in a
tclish way. I don't know who's idea is it to implement [apply] but the
paradigm shift of having a command to create lambdas to having a
command that treats strings as lambdas is genius -- very tclish.
Actually, the word "apply" is not needed.
It is like using the word "CALL" for procedure invocation.
In Tcl, the first word IS the proc name to be called.
So why "apply"?
Being the first word in line, lambda must be automatically called.
Because the lambda is an anonymous proc - it has no name. As you said,
the first word IS the proc name - so it can't be the lambda.
One could do without - e.g. with some [unknown] trickery as shown
above. But that's not very efficient.).
You don't have to store lambdas in variables, you can also [interp
alias] them:
interp alias {} do_something {} apply {{..} {...}}
Although, of course, if you are doing this then it is best to just use a
regular named procedure. The most likely use of a lambda is when it is
passed either to or from a procedure as an argument/return value, so no
importing would be needed.
-- Neil
I would say, that tricks are very inefficient :) - hope they are not
going to be common.
Transparent lambda calls should have been built-in, not emulated.
>).
Well.. it is not just so simple.
There are already several separate tables to search for command name:
built-in commands, global procs, package procs, namespaces, aliases..
The interpreter just need to recognize the special form of lambda as a
"command name". This will make happy everyone :)
Moreover.. I hope, lambdas are not being compiled every time before
execution. There must be some kind of cache.
So, just one more table to lookup..
As for apply, it should accept ordinary proc names then.
No.
All of those things are commands. They are all found in a
command table.

> Transparent lambda calls should have been built-in, not emulated.
Why? Does it seriously pain you having to write [apply $fun a b] rather
than just [$fun a b]? That seems to me like a fairly small matter of
syntax for very little gain over what [apply] already provides.
Especially when you consider that lambdas are typically used as
callbacks, and callbacks are usually evaluated with either [eval] or
[uplevel] which neatly allows you to avoid any problems. For example,
did you realise that [apply] works nicely with pretty much every command
in the Tcl and Tk libraries that takes a callback?
# I always recommend using a constructor for lambdas:
proc lambda {params body} { list apply [list $params $body] }
lsort -command [lambda {a b} { ... }] $xs
http::geturl $url -command [lambda tok { ... }]
after 1000 [lambda {} { puts "Hello!" }]
socket -server [lambda {sock addr port} { ... }] 8080
trace add variable foo write [lambda {v1 v2 op} { ... }]
etc etc
These all work fine, as do the great majority of callbacks in tcllib and
other packages. Indeed, I can't think of a counter-example of the top of
my head. So, what exactly isn't transparent about lambdas using [apply]?
...

Such an idea was proposed and rejected at the time. [apply] works fine
without any new special forms being introduced and is syntactically
convenient for 95%+ of all use cases I can think of.

That is correct, the byte-code is cached.
> So, just one more table to lookup..
The byte-code is cached directly in the lambda internal representation,
so there is no table lookup (that I know of). If you feel there are
performance problems with [apply] then supply some figures.
-- Neil
The worst thing is that lambda implementation proposed in 8.5 doesn't
make lambdas look like ordinary procs.
In every language that support lambdas, it doesn't matter whether a
function has name or not. Reference to lambda is equal to named
function reference in any use case.
But what do we have in Tcl?
If I store an ordinary proc "reference", it is called this way:
% set XX puts
% $XX 123
But if I store lambda, I have to KNOW that!
% set XX {{x} {puts $x}}
% $XX 123 ;# This will NOT work!
% apply $XX 123
What's next?
Suppose, "apply" will accept proc names.
But I don't want to write dummy "apply" for every call. It's not
Fortran! :)
Sweet.. so the variable itself is marked as a lambda then? (this means
that lambda is just a "type" of object.. like integers, strings,
arrays and lists?) If so does [eval] do the same? Also, does it mean
that the following doesn't get bytecompiled? :
# lambda not stored in a variable:
apply {{x y} {set x [expr {$y*$x}];puts $x}} 20 20
Okay, I have really overlooked this.
This is handy.

This means that variable containing "{{a b} {return a+b}}" will be
compiled (at first use? at assignment? - it doesn't matter) and
cached.}}
;)
And one more advantage.
With apply, deep lambda call stack would have incomprehensible look -
bunch of "apply"'s.
On the contrary, if one had lambdas as commands, they would be visible
on the stack. [info level] would remain usable as well.
You are not "thinking in Tcl".
The string "{{a b} {return a+b}}" is just a string. When [apply]
encounters it, it interprets it as an anonymous proc and runs it. If you
send it to eg [llength], it will be interpreted as a list. Values are
just strings, commands may interpret them in different manners. An
interesting exercise is to type at the prompt
set set set
and then ask: is "set" now a command? a variable? a variable's value?
The only answer reasonable answer in Tcl is "yes" ...
The fact that anonymous procs are bytecompiled (and the bytecodes are
saved/cached) is just a performance hack.
A variable cannot be compiled - its value can. Note that when you do
set L0 {{a b} {return a+b}}
set L1 $L0
{*}$L0 1 2
the value of L0 is now bytecompiled ... as is the value of L1, they are
the same!
>}} ;)
Considered, rejected. If lambdas are command names you lose the
automatic lifetime management ("garbage collection"), which is very
important. Commands are long-lived, they exist and occupy memory as long
as you do not delete them. These anonymous procs do not.
You may find it interesting to read the tips in this area: and.

Would? Have you actually tried it?
% proc showCaller {} {puts **[info level -1]; moo}
% apply {args showCaller} can I see this?
**apply {args showCaller} can I see this?
invalid command name "moo"
% set errorInfo
invalid command name "moo"
while executing
"moo"
(procedure "showCaller" line 1)
invoked from within
"showCaller"
(lambda term "args showCaller" line 1)
invoked from within
"apply {args showCaller} can I see this?"
If you have concrete suggestions as to how to make the call stack
clearer or more useful, please file a bug or RFE.

No - it's not stored, but "executed immediately". Take

This is sugar-coated for
> > trace add variable foo write [list {v1 v2 op} { ... }]
and what gets stored is the two-element {argl body} list. This, when
first [apply]ed, gets compiled, and on later calls just the bytecode
is executed.
Aargh!!! Serves me right for posting before breakfast ...
Either of
set L0 {{a b} {return a+b}}
set L1 $L0
apply $L0 1 2
or
set L0 [list apply {{a b} {return a+b}}]
set L1 $L0
{*}$L0 1 2
An by the way: I am using your proposed body ... it returns the string
"a+b" for any input. I do imagine you wanted
{{a b} {expr $a+$b}}]
which returns the sum.
I wonder, if the bytecode is attached to the whole thing, or just to
the body.
If it's attached to the whole "{params} {body}" thing, then a simple
[llength $function] would replace the bytecode-rep with the list-rep,
and next time it's got to be recompiled. (otoh, why should someone
treat the lambda as list? perhaps to check for a namespace? or use
lindex as pendant to [info args/body]? not too likely to happen
repeatedly enough to be an issue)
If it's "compiled" to a list, only whose second item has the actual
bytecode attached, then it could perhaps be recombined with a different
parameter list, and result in unexpected behaviour ...
Or is it done even differently (e.g. such that both list-information and
lambda-information is maintained together? also the string-rep?)
PS: I know, as a scripter I shouldn't care about these internals, but
I'm just curious...
Heh: the correct answer is RTFS, but you are so nice and polite about it
... what the hell.
The whole [list $params $body ?$ns?] is converted to lambdaType. If you
for instance request the llength, the type shimmers and the bytecompiled
code is lost - it will be regenerated at the next usage.
No, that will get byte-compiled. The bytecode is stored in the internal
rep of the Tcl_Obj, not any particular variable. In other words, the
Tcl_Obj used to represent {{x y} {set x ...}} gets a compiled proc
stashed in its internal rep. This bytecode is generated the first time
that value is passed to [apply] and then sticks around until someone
messes with the internal rep.
Note that originally, apply was going to take the arguments separately:
[apply params body args...]. Miguel pointed out that the bytecode
depends on both the script body *and* the parameter list, which is why
they are now combined into a single argument, to give a handy place to
stash the bytecode.
-- Neil
This isn't an artefact of lambdas, but rather that Tcl has a distinction
between command and variable namespaces, and that it expects a command
*name* not a command itself. Common Lisp is an example of another
language which makes this distinction and also has this same problem:
(defun adder (n)
(lambda (x) (+ x n)))
((adder 1) 2)
--> ERROR: illegal function call
(funcall (adder 1) 2)
--> 3
(apply (adder 1) '(2))
--> 3
Tcl's [apply] is roughly equivalent to CL's (funcall) or (apply).
To get to something like Scheme or Haskell in Tcl, you could drop
variables and use commands for everything:
proc def {name = args} { interp alias {} $name {} {*}$args }
def XX = puts
XX "Hello, World!"
def XX = apply {{x} {puts $x}}
XX "Hello, World!"
Although, of course you lose local variables! I also prefer the Scheme
situation, but that's a bigger change to Tcl than just lambdas.
-- Neil
On the other hand, if you're combining with actual parameters then you
are using the form:
[list apply [list $params $body ?$ns?] $arg1 $arg2 ...]
and in that case adding extra arguments to the outer list won't hurt.
(It's the inner former-list that holds the bytecode inside it.)
Donal.
Not in Common Lisp or in any of the earlier Lisp dialects.
2-Lisps use (FUNCALL) to call procedure values.
> But what do we have in Tcl?
If Tcl is like Lisp at all, it's like a 2-Lisp.
[apply] is Tcl's rough equivalent of Lisp's (FUNCALL).

You might prefer 1-Lisps (so do I), but Tcl just ain't like that,
and it don't work that way.

Train Networks Using Deep Network Designer
The Deep Network
Designer app lets you build and train deep neural networks. Deep Network Designer
supports
trainNetwork training using image data or
datastore objects. You can also export your untrained network for training at the command
line, for example, to train your network using custom training loops.
To train a network, follow these steps:
Create network
Import data
Select training options
Train network
Export network
You can build a network interactively using Deep Network Designer, or import a network from the workspace. You can also select a pretrained network from the Deep Network Designer start page for transfer learning. For more information, see Build Networks with Deep Network Designer.
To train a deep learning model, you must have a suitable network and training data. To
import image data from a folder containing a subfolder of images for each class, or from an
imageDatastore object, on the
Data tab, click Import Data > Import Image Data. To import any datastore, on the Data tab, click Import Data > Import Datastore. After import, Deep Network Designer displays a preview of the imported data
so that you can check that the data is as expected prior to training. For more information,
see Import Data into Deep Network Designer.
Select Training Options
Once you have your network and data, the next step is to select the training options.
On the Training tab, click Training Options.
If you do not know which training options to use, try training with the default settings
and then adjusting them to suit your network and data. For example, try adjusting the
initial learning rate, or train for longer by increasing the number of epochs. For
information about techniques for improving the accuracy of deep learning networks, see
Deep Learning Tips and Tricks. For more information
about the training options, see
trainingOptions.
Train Network
After you select your training options, train the network by clicking Train. The Deep Network Designer app displays an animated plot of the training progress. The plot shows mini-batch loss and accuracy and additional information on the training progress. If you specified validation data, the plot also shows the validation loss and accuracy. The plot has a stop button in the top-right corner. Click the button to stop training and return the current state of the network. For more information on the training progress plot, see Monitor Deep Learning Training Progress.
You can train a variety of networks using Deep Network Designer. For example, image
classification or regression networks, sequence networks, numeric data networks,
semantic segmentation networks, and image-to-image regression networks. In Deep Network
Designer, you can train a network using the
trainNetwork function
on any data that you can express as a datastore object. The following examples show how
to build and train a network using Deep Network Designer.
Once training is complete, on the Training tab, click Export to export your trained network and results to the workspace. To save the training progress plot as an image, click Export Training Plot. You can learn how to build and train your network using command line functions by clicking Export > Generate Code for Training and examining the generated live script.
Deep Network Designer does not support training using custom training loops..
Next Steps
Once training is complete, click Export > Create Experiment to create a deep learning experiment in Experiment Manager. You can use Experiment Manager to sweep through a range of hyperparameter values or use Bayesian optimization to find optimal training options. For an example showing how to use Experiment Manager to tune the hyperparameters of a network trained in Deep Network Designer, see Generate Experiment Using Deep Network Designer.

From risk to opportunity Lecture 11 John Hey and Carmen Pasca
2
Lecture 11 Implications of EUT Finding your (EU) utility function… … two different ways. Defining risk aversion and risk loving. Defining two indices of risk aversion. Some special utility functions with nice properties. Examples of its use in economics: 1.The theory of the competitive firm facing price uncertainty. 2.The life-cycle savings problem under income risk.
3
Lecture 11 Implications of EUT: Finding your (EU) utility function 1 Finding your utility function over [x, X]. Here we are using x to denote the lower bound and X the upper bound of the interval over which we are going to find your (EU) utility function. There are lots of ways to find it. Here is just one. Put u(x)=0 and u(X)=1. To find the utility value for some intermediate amount x i answer the question: “what probability u i in the gamble [X,u i ;x,(1-u i )] makes you indifferent between that gamble and x i ?”. It immediately follows that u(x i ) = u i. Repeat for lots of different values of x i. Example, put x= €0 and X= €100. Suppose you are risk-averse and you are indifferent between €50 and the gamble [€100,0.75; €0,0.25] then for you u(€50) = (Note EX=€75>€50.)
4
Lecture 11 Implications of EUT: Finding your (EU) utility function 2 Here is another way: interpolation. Suppose that you have already found x a and x b such that, for you, u(x a )=a and u(x b )=b. To find your utility value half-way in-between answer the question: “what amount of money x (a+b)/2 makes you indifferent between that amount and the gamble between x a and x b ; that is the gamble [x a,½;x b,½]?”. It immediately follows that u(x (a+b)/2 ) = (a+b)/2. Example, suppose a=0.5, x a =25; b=0.7, x b =49 and you are indifferent between €36 and a gamble between €25 and €49 then for you u(36) = 0.6. Note this latter gamble has expected value €37 – you are risk-averse (and your function is concave between €25 and €49).
5
Lecture 11 Implications of EUT: Certainty Equivalent For a given individual we define his or her certainty equivalent, CE, of some lottery/gamble as the amount of money, which, if received with certainty, the individual regards as the same as the lottery. So u(CE) = Eu(X) where X is the amount received in the lottery, CE denotes the Certainty Equivalent and where u(.) is the individual’s utility function. Example: lottery is 50:50 chance of €16 or €4. (Note that EX = 10.) Suppose u(x) = x 0.5. Then Eu(X) = 0.5u(16) + 0.5u(4) = 0.5(4)+0.5(2) = 3. And hence the CE is given by u(CE)=3. Hence CE = 9.
6
Lecture 11 Implications of EUT: Risk Premium For a given individual we define his or her risk premium, RP, for some lottery/gamble as the amount of money he or she would pay to convert the lottery into its expected value. So RP = EX – CE, where CE is the individual’s certainty equivalent for the gamble. Example: lottery is 50:50 chance of €16 or €4. (Note that EX = €10.) Suppose u(x) = x 0.5. Then Eu(X) = 0.5u(16) + 0.5u(4) = 0.5(4)+0.5(2) = 3. And hence the CE is given by u(CE)=3. That is CE = €9. And so the RP = 10 – 9 = 1; the individual would pay up to €1 to exchange the lottery for the certainty of €10.
7
Lecture 11 Implications of EUT: Risk aversion We define a risk-averse person as one who (always) prefers a certainty to a risk with the same expected value. So his or her certainty equivalent for some lottery is (always) less than the Expected Value of the lottery; the risk premium is always positive. This implies that his or her utility function is (everywhere) concave. Let us continue with the example where u(x) = √x = x 0.5 (concave) and where the lottery is a 50:50 chance of 16 or 4. What is the expected value of this lottery? 0.5(16) + 0.5(4) = 10. And the CE? 9. See the next slide.
8
Lecture 11 Implications of EUT: Concave utility Gamble pays €4 with probability ½ and €16 with probability ½. Expected Value is €10 Certainty equivalent is €9 because u(9) = 3 = ½ u(4) + ½ u(16) = EU(X) Risk Premium = €1 = €10 - €9 = EX- CE
9
Lecture 11 Implications of EUT: risk attitudes An individual is everywhere risk-averse (-neutral, -loving)… …if his or utility function is always concave (linear, convex) … if his or her certainty equivalent for some risk is always less than (equal to, more than) the expected value of the risk. … if he or she is always willing to pay a positive (a zero, a negative) amount to turn a risk into a certainty with the same expected value. The degree of concavity (convexity) indicates the degree of risk-aversion (loving).
10
Lecture 11 Implications of EUT: measuring risk attitude The degree of concavity indicates the degree of risk aversion. Concavity of a function is to do with its second derivative. But as the function is unique only up to a linear transformation, it has to be divided by the first derivative. Absolute risk aversion index = -u”(x)/u’(x) Relative risk aversion index = -xu”(x)/u’(x)
11
Lecture 11 Implications of EUT: CARA and CRRA For one who has Constant Absolute Risk Aversion: If we add some constant to all the outcomes of a gamble, the CE of that gamble rises by the same constant and hence the Risk Premium stays the same. From -u”(x)/u’(x) = r we get u(x) is proportional to –e -rx [unless r=0 in which case is proportional to x] If X is N(μ,σ 2 ) then Eu(X) proportional to –exp(-rμ+r 2 σ 2 /2). For one who has Constant Relative Risk Aversion: If we multiply by some constant to all the outcomes of a gamble, the CE of that gamble is multiplied by the same constant and hence the Risk Premium is multiplied by the same constant. From -xu”(x)/u’(x) = r we get u(x) is proportional to x 1-r [unless r=1 in which case is proportional to ln(x)] Note that the proportionality results from the fact that the utility function is unique only up to a linear transformation.
12
Lecture 11 Implications of EUT: the perfectly competitive firm Consider the perfectly competitive firm under output price uncertainty. p, the price, is risky with known density function. The cost function c(.) is known. The firm wants to maximise the Expected Utility of profits = π = px – c(x) by its choice of x, the output. Choose x to maximise Eu(π)=Eu[px – c(x)]. FOC is that E{u’(π)[p-c’(x)]} = 0. From this we can show c’(x) < Ep Firm produces less under risk. See Hey JD Uncertainty in Economics, Martin Robertson 1979 (now way out of print).
13
Lecture 11 Implications of EUT: life-cycle savings Life-cycle consumption/savings problem under income risk. Objective to maximise u(C 1 ) + ρu(C 2 ) + ρ 2 u(C 3 ) + … subject to W t+1 = R(Y t – C t + W t ) for all t. C, Y and W are consumption, income and wealth; ρ and R are the discount rate and the rate of return (1 plus the rate of interest). In general it can be shown that the optimal strategy is C* = a + b W, and that b=(R-1)/R So the marginal propensity to consume (out of wealth) depends only on the rate of interest/return. When the utility function is CARA, with r the index of absolute risk aversion and the distribution of income is N(μ,σ 2 ) it can also be shown (assuming r > 0) that a = μ – ½r(R-1)σ 2 –ln(Rρ)/[r(R-1] So the intercept of the consumption function depends positively on the mean of the income distribution and negatively on the variance; also if Rρ < 1 then increases in r and in R both lead to decreases in the intercept. Hey J D, “Optimal Consumption under Income Uncertainty”, Economic Letters, 5, 1980,
14
Lecture 11 Implications of EUT: Conclusions The great joy of EUT is its elegance and tractability. It is easy to find your (EU) utility function. It is concave (linear, convex) where you are risk- averse (-neutral, -loving). The degree of risk-aversion can be measured by the degree of concavity of the utility function (using either an absolute or a relative measure). CARA and CRRA are to useful special cases… … which lead to insightful results.

Hi
Hm, ok, I see. I'll move it to arch/mips/include/asm/mach-jz4740/ then.
But I guess I should move the headers for all the other jz4740 driver to the
same
directory as well.
On the other hand I'm wondering where on would put headers for non platform
specific
drivers?

Arch IFC
Description
The
Arch and
BIM Workbenches feature an Industry Foundation Classes (IFC) importer and exporter. The IFC format is a continuously growing format to interchange data among BIM applications, used in architecture and engineering.
Both the importer and exporter depend on the IfcOpenShell library, which is bundled in some distributions of FreeCAD. An easy way to check if IfcOpenShell is available is to enter the following in the Python console:
import ifcopenshell
If no error message appears, IfcOpenShell is installed, and you may proceed with importing IFC files. Otherwise, you will need to install IfcOpenShell yourself; read the IfcOpenShell page to learn more about this process.
Note: the
BIM Setup tool will look for IfcOpenShell too, and issue a notification if it is not installed.
Note 2: in the past (2013) the Arch Workbench used to feature a simpler IFC importer that didn't depend on IfcOpenShell. This legacy module is still included in the source code but as of v0.19 it is not recommended at all; it will only be able to import a very small subset of IFC objects, and should be considered completely obsolete..

With the problem of form context solved with Formik, developers are free to focus on the behaviour they are aiming to achieve from their forms.
In this post, we’ll look at how we can build better React forms with Formik. Formik is a small library that helps you with the three major React form issues:
By fixing all of the above, Formik keeps things organized, thereby making testing, refactoring and reasoning about your forms a breeze. We’ll look at how Formik helps developers build better React forms while handling those three issues.
You can install Formik with NPM, Yarn or a good ol’
<script> via unpkg.com.
$ npm install formik --save, Formik also has a global (“UMD”) build hosted on the unpkg.com CDN. Simply add the following script tag to the bottom of your HTML file:
<script src=""></script>
Let’s look at how Formik handles one of the major React form issues of passing values around in React forms.
Consider an example where we have two input fields for email and password. We want to log the values of these fields to the console when the form is submitted. With the usual React form, we can create this form like so:
import React, { Component } from 'react'; class App extends Component { constructor(){ super() this.state = { email: '', password: '' } this.handleEmailInput = this.handleEmailInput.bind(this) this.handlePasswordInput = this.handlePasswordInput.bind(this) this.logValues = this.logValues.bind(this) } logValues (){ console.log(this.state.email); console.log(this.state.password); }; handleEmailInput (e) { this.setState({ email: e.target.value }); }; handlePasswordInput (e) { this.setState({ password: e.target.value }); }; render() { return ( <form onSubmit={this.logValues} > <input type="email" onChange={this.handleEmailInput} value={this.state.email} <input type="password" onChange={this.handlePasswordInput} value={this.state.password} <button onClick={this.logValues}> Log Values </button> </form> ); } } export default App;
Here, you’ll notice that we have a state object that manages the state of the form. We’ve also defined handlers to manage the state of the input fields, the values, the changes and so on. This is the conventional way of creating forms in React, so let’s skip all the explanations and get to the Formik part.
With Formik, this could be better, even neater and, oh, done with less code. Now let’s try recreating this exact functionality with Formik:
import React from 'react' import { withFormik, Form, Field } from 'formik' const App = ({ values, handleSubmit, }) => ( <Form> <Field type="email" name="email" placeholder="Email"/> <Field type="password" name="password" placeholder="Password"/> <button>Submit</button> </Form> ) const FormikApp = withFormik({ mapPropsToValues({ email, password}) { return { email: email || '', password: password || '', } }, handleSubmit(values){ console.log(values) } })(App) export default FormikApp;
Did you notice how clean and simple it was to recreate the form with Formik? Yeah, you did. Now, let’s walk you through it. Here, we used withFormik() to create the FormikApp component. WithFormik takes in an option, which, according to Formik docs, is a list of objects that we can pass into the withFormik() method to define its behavior.
In this case, we have passed in the mapPropsToValues({ }) option as a function which itself takes in the values of the input fields and passes them as props to our App component. In the App component we can access the values of all the input fields simply by destructuring it and passing in the Formik props called values, which is just an object with a bunch of key/value pairs.
With Formik, we don’t have to define an onChange handler or even an onSubmit on the form, it all comes built-in. All we have to do is import the Form prop from Formik and destructure it in the App component. With that done, we can use it to create our form fields.
Finally, with Formik, we don’t have to define a value in the input field. We simply import the Field prop provided by Formik and it saves us the stress of all those boilerplate codes.
In React, there is no simple way to handle validation in forms as at this time. Don’t get me wrong, there are good ways — just not as simple as Formik makes it. If you have created a sign-up form before in React, you’ll understand that you had to write your own validation logic to make sure users comply to your standards. You probably had to write a lot of code to validate the email input field, password, number, date and even your own error messages.
With Formik, we can use Yup to handle all that. It is so simple that you can implement standard validation in your input fields in less than 10 lines of code. That’s not all. It also allows you to define your custom error messages for every field condition you check.
Continuing from our last Formik form example, let’s validate the email and password fields with Yup:
import React from "react"; import { withFormik, Form, Field } from "formik"; import Yup from "yup"; const App = ({ values, handleSubmit, errors, touched }) => ( <Form> <div> {touched.email && errors.email && <p>{errors.email}</p>} <Field type="email" name="email" placeholder="Email" /> </div> <div> {touched.password && errors.password && <p>{errors.password}</p>} <Field type="password" name="password" placeholder="Password" /> </div> <button>Submit</button> </Form> ); const FormikApp = withFormik({ mapPropsToValues({ email, password }) { return { email: email || "", password: password || "" }; }, validationSchema: Yup.object().shape({ email: Yup.string().email().required(), password: Yup.string().min(6).required() }), handleSubmit(values) { console.log(values); } })(App); export default FormikApp;
Here we have implemented validation and error reporting for both the email and password fields with the addition of about seven lines of code. How is this possible, you might ask? Well, let’s tell you how. In the FormikApp component, we passed in another option, validationSchema to withFormik({ }), which automatically handles all the validations for us.
With the errors prop we just destructured in the App component props, we now have access to the validationSchema errors. As a result, we can define a text field above the input fields to show the validation error messages to the users.
Finally, to be certain that the error messages appear only during submission (not when the user is typing), we used the touched prop. That way, we can conditionally check if a certain field has been touched. If it has, check if there are any errors; if there are, show the text when the field is submitted.
So far, if you run this App and try submitting false values, this is the output you’ll get:
That is all well and good, but what if we wanted to provide a custom error message for the individual validation checks? With Formik, we can do this by specifying the messages inside the validationSchema methods like this:
validationSchema: Yup.object().shape({ email: Yup.string() .email("Invalid Email !!") .required("Email is required"), password: Yup.string() .min(6, "Password must be above 6 characters") .required("Password is required") }),
At this point, the error messages will update appropriately with the contents that we have defined:
Formik gives us the functionality to make asynchronous requests even on submission of the form. Sometimes we’ll want to check if the submitted email address already exists in the database, and if it does we report it to the user.
Also, while the asynchronous request is running, we may want to dynamically disable the submit button until the execution completes. Formik provides us all this functionality and more. To further demonstrate this, let’s simulate a scene where, if an email address already exists, we’ll report an error to the user after the asynchronous request, which we have replaced with a timeout of two seconds. Then if the supplied email address doesn’t exist yet, we reset the form.
To do this, we’ll pass in the necessary Formik props as the second argument to the handleSubmit handler in our FormikApp component like this:
handleSubmit(values, {resetForm, setErrors, setSubmitting}) { setTimeout(() => { if (values.email === "john@doe.com") { setErrors({ email: 'Email already exists'}) } else { resetForm() } },2000) }
Wonderful, now we can perform dynamic asynchronous operations while submitting forms. You may have noticed that we still have an unused argument setSubmitting, and you’re probably wondering why we have it there if we are not going to use it. Well, we are.
We’ll use it to conditionally disable our submit button when a submission operation is running. All we need to do is access a prop that is passed to our App component called isSubmitting. As the name suggests, it is a Boolean. If we are submitting, the value is true so we can do something, and if we are not, it’s false, and we can do something else.
const App = ({ values, handleSubmit, errors, touched, isSubmitting }) => ( <Form> <div> {touched.email && errors.email && <p>{errors.email}</p>} <Field type="email" name="email" placeholder="Email" /> </div> <div> {touched.password && errors.password && <p>{errors.password}</p>} <Field type="password" name="password" placeholder="Password" /> </div> <button disabled={isSubmitting}>Submit</button> </Form> );
Then in the handleSubmit handler, we just set setSubmitting to false:
handleSubmit(values, {resetForm, setErrors, setSubmitting}) { setTimeout(() =>{ if (values.email === "john@doe.com") { setErrors({ email: 'Email already exists'}) } else { resetForm() } setSubmitting(false) },2000) }
Now whenever a submit operation is running, the submit button is conditionally disabled until the asynchronous operation is done executing.
This is Formik at the barest minimum. There are a ton of things you can do with Formik that we didn’t touch in this post. You can go ahead and find out more yourself in the documentation and see how you can optimize the React forms in your existing application or how to implement these amazing features in your subsequent React apps. Compared to the conventional way of creating forms in React, Formik is a must have.

Great article Shubham, Even the React official documentation site mentions Formic as one solution for creating forms in Creat. However I would highly recommend developers understand the concept of controlled components and uncontrolled components.
I have taken a stab at it in one of my blog posts.

A while ago I wrote an article about creating a contact form using React and PHP. Many people found it interesting. So, here I am writing an updated version of that article.
Check out the article about creating a contact form with React and PHP:
Hooks are a new addition in React and we are going to re-create the contact form using React Hooks.
Same as the previous project. This tutorial is beginners friendly. You don’t have to be an expert in Javascript, React, or PHP but I won’t go into basic details like installing React and setting up the project.
I assume you already have an up and running React project. We will focus on creating the component.
If you have a component folder in your project please go ahead and create a ‘Form’ folder inside it. It is up to you to decide where the component should live. Once you created the folder let’s create the ‘index.js’ file.

Activating Perl 6 syntax highlighting in Vim
Modern versions of the Vim text editor ship with Perl 6 syntax highlighting, but automatically activating it is tricky because Perl 6 files can have ambiguous file extensions. It can get tiresome to correct the file type every time you open a Perl 6 file, so I’m going to show you a few tricks that I use to make Vim detect Perl 6 files automatically.
Showing and setting the filetype in Vim
First of all I want to make sure that syntax highlighting is turned on by default, so I add this option to my
.vimrc:
syntax on
To edit your
.vimrc just start Vim and enter this command
:e $MYVIMRC. Save your changes with
:w, and then reload your
.vimrc with
:so %.
Now that I have syntax highlighting turned on, I need to know how set Vim’s file type to Perl 6 when I’m working with Perl 6 files. I can see the current file type by typing this command
:set filetype?. To set the file type to Perl 6, I use this command
:set filetype=perl6. The
filetype keyword can be shortened to
ft. In which case the last command becomes
:set ft=perl6.
Detecting Perl 6 files
Now the challenge becomes correctly detecting when I’m working with Perl 6 files in Vim. Perl 6 scripts shouldn’t be a problem: Vim (not Vi) automatically parses the shebang line to determine the file type. However this fails when the script has an extension like
.pl.
Use the .pm6 file extension
Vim will automatically use Perl 6 syntax highlighting if the file extension is
.pm6. So when working with Perl 6 module files, it’s better to use this extension. This doesn’t help when I’m working on other people’s Perl 6 projects however. It also doesn’t help for test files, which do not have an equivalent Perl 6 file extension (
.t6 test files are ignored when installing Perl 6 modules).
Use a modeline
A modeline is a line of code in the text of the file which Vim reads and executes. So to activate Perl 6 syntax highlighting I just need to add this modeline to every Perl 6 file I work with:
# vim: filetype=perl6
Take a look at the source code of JSON5::Tiny for a real-World example. To Perl 6 this code looks just like an ordinary comment, but Vim will use it to turn on Perl 6 syntax highlighting. The modeline can appear anywhere in the code, but it’s better to place it at the start or end of the file.
Older versions of Vim (pre 7.3) and when Vim is run under root privileges, disable modelines as a security risk. Don’t run Vim as root! But if you have an older Vim, you can turn on modelines with
:set modeline. As with
filetype, modeline can be abbreviated to
ml, so
set ml works too. To activate modelines automatically, add this line to your
.vimrc:
set ml
The downside of using modelines? First there is aforementioned security risk for older Vims. Also it feels impure to add editor directives to the code I’m working with, as not everyone uses Vim. These seem like minor issues though.
Use a local vimrc
Often different Open Source projects will have different coding conventions that I need to follow, so it can be helpful to use a local vimrc file to store these project-specific settings. This works for syntax highlighting too. In order to use local vimrc files, I add the following code to my
.vimrc:
if filereadable(".vimrc.local") so .vimrc.local endif
This will check the current working directory for
.vimrc.local file, and automatically execute it if it finds it. Warning this is a security risk - Vim will execute ANY instruction in a local vimrc, so I am very careful when working with projects that are not my own. Next I create a
.vimrc.local file in the root project directory and add this auto command to it:
au Bufnewfile,bufRead *.pm,*.t,*.pl set filetype=perl6
Now when I open or create any file with a Perl extension, Vim will set the syntax highlighting to Perl 6. I like this technique because it’s not intrusive: it doesn’t require any changes to the Perl 6 files themselves, so it works well on shared projects (I never check-in my local vimrc to the Git repo).
Use code detection
I can also have Vim try to detect Perl 6 code automatically. Two directives which would indicate we’re working with Perl 6 instead of Perl 5 code: the shebang line and the
use v6; directive. To check for these, I’ll add a function to my .vimrc:()
This function uses
getline() to check the first line of the file to see if it looks like a Perl 6 shebang. This should work well for
.pl scripts, but Perl 6 module files will not have a shebang, so the next part of the script checks the first 5 lines of the file for the
use v6; directive. The last line of code is an auto command which will call the function anytime we open file with a Perl file extension.
The main drawback of this technique is that not all Perl 6 code uses the
use v6; directive, and so when working with module files, the code detection can fail. However the code detection could be improved to use more rules for detecting Perl 6 code such as class declarations. The vim-perl plugin has more sophisticated Perl 6 code detection rules.
Complete .vimrc
This
.vimrc contains all the code shown above:
syntax on "Recognize modeline # vim: filetype=perl6 set ml "check for a local vimrc if filereadable(".vimrc.local") so .vimrc.local endif "check for Perl 6 code()
Conclusion
So that’s it, four useful-but-imperfect techniques for detecting file types in Vim. I tend to use a combination of all four. This would be a nice problem not to have. I’d like the Perl 6 community to agree and encourage unambiguous file extensions like
.pm6,
.t6 and
.pl6. Larry Wall called this “free advertising”. It’s also a simple way to make Perl 6 programmers more productive. Not every text editor is as customizable as Vim.

Despite monastic rules that forbid it, monk Keo Heng has smoked two packs a day for
the last 10 years.
"When we are stressed or bored, a cigarette is like a good friend that makes
our brain clear," said Heng, 30, who lives at Wat Entagnean in Sihanoukville.
But like a growing number of smokers, Heng realized that cigarettes gave him nothing
and took quite a lot. They were eating away his money and his health - so he decided
to quit.
While tobacco use in Cambodia is still widespread, the number of quitters is on the
rise, according to several surveys published recently.
One of them, produced by the Adventist Development and Relief Agency, researched
monasteries in Phnom Penh and four other provinces and found that 23 percent of the
sangha had smoked cigarettes during the previous year, a sharp drop from the 36 percent
they found in the same provinces in 2001.
The survey results were presented during the second National Workshop on Buddhism
and Tobacco Control, held in Phnom Penh May 10 and 11.
Other statistics cited at the conference also showed progress for the anti-tobacco
lobby.
The percentage of male smokers aged 20 years or over fell from 59 percent in 1999
to 54 percent last year, according to a 2004 nationwide survey conducted by the National
Institute of Statistics.
The research found that the number of adult women who used tobacco products had also
dropped 1 percent since 1999 to 6 percent in 2004.
The results are encouraging, but health experts know there is still along way to
go in reducing the negative effects of smoking in the Kingdom.
About 80 percent of children under 13 years old are exposed to secondhand smoke from
at least one regular smoker in the family, said Yel Daravuth, national program coordinator
of the Tobacco Free Initiative at the World Health Organization (WHO).
Daravuth said many people in rural areas believe that smoking homegrown tobacco will
not damage their health as much as commercially produced cigarettes.
"It is a big confusion," Daravuth said.
As well as a gnawing away at smokers' health, cigarettes also take a bite from their
pocketbook.
The average monthly expenditure on tobacco products per household is 14,000 riel,
or $69 million nationwide in 1999, according to one report from the WHO.
That's enough to buy 274,304 tons of high quality rice, or build nearly 28,000 big
wodden homes.
Lim Thaipheang, director of the National Center for Health Promotion estimates that
at least 20 cigarette companies operate in Cambodia and advertise in the media.
"I am not in favor of the advertising, but we do not have the law to ban them,"
Thaipheang said.
The law on tobacco control was drafted in 2001 and is now under consideration at
the Council of Ministers, said Ung Phyrun, secretary of state at the Ministry of
Health.
He said when the law on tobacco control is approved, tobacco advertising will be
banned, its sales near schools and health facilities prohibited, and the tax on its
import increased.
The World No Tobacco day will be held on May 31 with the theme 'Health Professionals
and Tobacco Control'. | https://www.phnompenhpost.com/national/your-money-or-your-life-smokers-give-both | CC-MAIN-2018-34 | refinedweb | 531 | 55.68 |
This article focuses on setting up a continuous integration pipeline for a Django project, but the information here can be extended to other Python projects, too. Django is a Python framework that is described as the “web framework for perfectionists with deadlines.” It is considered a great tool for creating Minimal Viable Products (MVPs) because it is easy to set up an application with a database and to run tests. It delivers high quality code and has excellent documentation. These features also benefit your users because it promises the fast shipping of new features.
Here are the steps we will take:
- Create a Django app
- Create tests for the app
- Dockerize the app
- Configure CircleCI
- Run locally
- Push to GitHub
- Add a badge
- Explore optimization with caching
Prerequisites
In order to go through this tutorial, you will need to have the following installed:
Create a Django app
Django Girls offers a great tutorial on the Django framework. We’ll start off with a blog application that is the result of completing the Django Girls tutorial and setup CircleCI for it. For the database, we’ll use a flat file:
.sqlite.
To get the blog app, clone this repo by typing this line into your terminal:
git clone
Then, enter the directory by running:
cd django_girls_complete
After I completed the tutorial from Django Girls, I made additional changes to the application’s codebase. Since these changes are not directly related to setting up CI for the project, I will just add links to the file changes in GitHub. The changes include:
- Updating the templates in the
blog/templates/blogdirectory and
settings.py.
- Adding a
.gitignorefile.
- Adding a
.editorconfigfile.
- Adding files to Dockerize the app. More on this later.
To see the original, run:
git checkout original
To get the codebase after my changes, run:
git checkout 1.1.0
From now on I will take us step by step through setting up our continuous integration pipeline. The folder structure of our app looks like this (I simply run
tree from my terminal to get this):
. ├── Dockerfile ├── LICENSE ├── README.md ├── blog │ ├── __init__.py │ ├── admin.py │ ├── apps.py │ ├── forms.py │ ├── migrations │ │ ├── 0001_initial.py │ │ └── __init__.py │ ├── models.py │ ├── static │ │ └── css │ │ └── blog.css │ ├── templates │ │ └── blog │ │ ├── base.html │ │ ├── post_detail.html │ │ ├── post_edit.html │ │ └── post_list.html │ ├── tests.py │ ├── urls.py │ └── views.py ├── docker-compose.yml ├── init.sh ├── manage.py ├── mysite │ ├── __init__.py │ ├── settings.py │ ├── urls.py │ └── wsgi.py └── requirements.txt 7 directories, 26 files
Creating tests for the app
Our CI pipeline needs to have tests so that we can ensure that our automated build is A-Okay before any new commit is merged. Writing tests with Django is extensively documented here.
First, replace the code in
blog/tests.py with:
from django.contrib.auth.models import User from django.test import TestCase from django.utils import timezone from .models import Post from .forms import PostForm class PostTestCase(TestCase): def setUp(self): self.user1 = User.objects.create_user(username="admin") Post.objects.create(author=self.user1, title="Test", text="We are testing this", created_date=timezone.now(), published_date=timezone.now()) def test_post_is_posted(self): """Posts are created""" post1 = Post.objects.get(title="Test") self.assertEqual(post1.text, "We are testing this") def test_valid_form_data(self): form = PostForm({ 'title': "Just testing", 'text': "Repeated tests make the app foul-proof", }) self.assertTrue(form.is_valid()) post1 = form.save(commit=False) post1.author = self.user1 post1.save() self.assertEqual(post1.title, "Just testing") self.assertEqual(post1.text, "Repeated tests make the app foul-proof") def test_blank_form_data(self): form = PostForm({}) self.assertFalse(form.is_valid()) self.assertEqual(form.errors, { 'title': ['This field is required.'], 'text': ['This field is required.'], })
What we’ve added is a
PostTestCase class extending from
django.test.TestCase with four methods:
- In the
setUpmethod, defined as
def setUp(self), we create one user,
self.user, and a post by that user.
- The
test_post_is_postedmethod confirms that the text of the post titled Test is We are testing this.
- The
test_valid_form_datamethod confirms that the form saves correctly: a title and text is filled on the form to create a post, the post is saved, and its title and text confirmed to be correct.
- The
test_blank_form_datamethod confirms that the form will throw an error when neither title nor text is filled.
Second, run the following command:
python manage.py test
Note: This command builds a test suite out of all of the test cases, extending
TestCase in any file whose name begins with
test and then runs that test suite.
The tests are passing! A breath of fresh air.
To start with the codebase after the tests have been added, run:
git checkout tests
Dockerize the app
Next up is Dockerizing the app. What does that even mean?
To Dockerize an app means to develop, deploy, and run an application in a container using Docker. This involves three key files:
.dockerignorefile: A
.dockerignorefile is to Docker what a
.gitignorefile is to Git. The files and/or folders listed therein will be ignored in the Docker context and will not be found within a Docker image. See our
.dockerignorefile here.
Dockerfilefile: Defines the steps to create a Docker image. See our
Dockerfilehere.
docker-compose.ymlfile: Whether you are running one service or multiple services, Docker compose removes the need to type out a long
docker runcommand and allows you to run one line,
docker-compose up, to spin up containers in the context of the file. See our
docker-compose.ymlfile here.
I also added an initialization script to be used when running the
Dockerfile. See our
init.sh file here.
CircleCI configuration
For us to integrate CircelCI into our project, we need to add a configuration file for a Python app. Create a
.circleci folder in the project’s root and add a
config.yml file. Copy these lines into it:
version: 2 jobs: build: docker: - image: circleci/python:3.6 steps: - checkout - restore_cache: key: deps1-{{ .Branch }}-{{ checksum "requirements.txt" }} - run: command: | python3 -m venv venv . venv/bin/activate pip install -r requirements.txt - save_cache: key: deps1-{{ .Branch }}-{{ checksum "requirements.txt" }} paths: - "venv" - run: name: Running tests command: | . venv/bin/activate python3 manage.py test - store_artifacts: path: test-reports/ destination: python_app
If this is your very first time doing this, you’ll notice four steps that may not be apparent:
checkout: This command fetches your source code over SSH to the configured path (the working directory, by default).
restore_cache: This command restores a previously saved cache.
save_cache: This command generates and saves a cache of a file, multiple files, or folders. In our case, we save a cache of the installed Python packages obtained after running
pip install ….
store_artifacts: This command stores logs, binaries, etc. so that they are accessible by the app in later runs.
Running the CircleCI build locally
I advocate that one installs the CircleCI CLI tool to run the build locally before pushing it to GitHub and running it on CircleCI. Running the build locally keeps you from having to commit code to your online repository to confirm that the build is passing. It quickens the development cycle.
You can install the CLI using Homebrew by running:
brew install circleci
Then, start by running the
circleci switch command:
You then run
circleci config validate to validate that your config file is written correctly and
circleci build to build the app:
The output from the commands concludes with Success! The local build ran successfully. With this check, we can now push the code to GitHub.
To start with the codebase after the tests have been added, run:
git checkout circleci
Pushing to GitHub
All we need now is to connect CircleCI to our code on GitHub and we will have the CI pipeline working like a charm: push code change, run test, merge if passing. Open GitHub in your browser and create a new repository. If you don’t have a GitHub account, you can create one here. After creating your repo, type these lines into your terminal:
git remote set-url origin git push -u origin master
Then, log into CircleCI to view the dashboard. If you don’t have an account, you can sign up for a free one here. On your dashboard page, click Add Projects and then click on the project name you are using. In my case, the name is
django_girls_complete. Notice the defaults that CircleCI sets for you:
- Linux OS
- Python Language
Since we already have a config file, click on
Start Building to run the job:
A successful run will look like this:
There you have it! That’s how to set up CI for Django projects. Type this into your terminal to run the application:
docker compose up
The app will be live at <0.0.0.0:8000>.
Adding a badge
You can have a number of integrations within your codebase. Having badges in your README is a best-practice that allows you to show others how the state of these integration services stand. It help others by letting them know how the state of these services stand. To get your badge, navigate to:<Username>/<Project>/edit#badges. In my case it is:.
Click the cog icon next to the name of the project:
Then, in the side menu, click Status Badges:
Copy the embedded code:
And, finally, paste it into your README, preferably close to the top, after the brief introduction of the repository. From the README, you’ll be able to see the build status of the most recent job in the default branch.
Exploring caching
In the screenshot showing the local CircleCI CLI run, you may have noticed the text in red:
Error: Skipping cache - error checking storage: not supported. Cache is not supported when running the CircleCI build locally.
For a CircleI job (a single run of the commands in a config file) to be faster, caching is implemented. More on this here. In our setup, we included steps for caching. For our learning, I ran the CircleCI job with and without caching to show us the advantage. Observe:
Starting from the lowest build, the extreme right tells us the time it took to run the job: 00:11 (11 seconds), 7 seconds, and so forth.
Caching is beneficial for us in overlooking the
pip install -r requirements.txt command if the
requirements.txt file is not modified. Of course, the first job just sets up the cache. It is no wonder that it took 11 seconds. We can assume that consecutive commits to GitHub without changing the
requirements.txt file will run in the range of 7 seconds. In the third job, I removed caching, and the time got returned to the range of the first: 11 seconds. On the fourth run, I restored caching resulting in a 20 second run. Finally, a rerun of that same job lasted 7 seconds, taking advantage of the cache again.
The seconds here might seem few and insignificant but with scale, the lost seconds can turn to minutes, even hours.
Conclusion
If you have followed the above instructions, you are well on your way of mastering continuous integration for your Django project(s). We started by creating a Django app and writing tests for it. Then we Dockerized the app so that we could build it in an isolated container. Doing this is beneficial because it results in only one dependency needed to run the app on any machine: Docker. The other dependencies for the app are all installed in the Docker container. We then went ahead and covered some best-practices in using CircleCI:
- Running the CI build locally with the CircleCI CLI
- Adding a badge and
- Utilizing caching for even faster builds.

Please help us make the Marketplace better! Take the survey
This is a console app-based project template to help you demonstrate how the standard query operators of the Language Integrated Query, LInQ work during your classes, courses or demos.
When creating the project template I had three goals in mind:
In order to realize these goals, basic console-app template is extended with a simple data model, a data repository and some extension methods.
After you install the extension, you'll find a new project template in Visual Studio:
The data model is based on the late-and-great Northwind database, or at least parts of it. You can find the elements of the data model inside the Model folder of the project.
The Product class represents a product that you can buy at a store.
The Category class represents a product category; basically a product group (e.g. "Books", "Drinks").
Note that everything is wired together by reference and there is exactly one of each object in the data source, no matter whether you access it directly from the data source, from the Category property of a Product or from the Products property of a Category. This is an important piece of information when discussing operators that do equality comparison, like the set operators, joins or GroupBy().
Note that both classes have their ToString() method overridden to return the value of their Name property.
Note that the namespace of the model classes, Model is already referenced in Program.cs. If you add other files, you have to add the reference to the namespace yourself.
Instances of the model classes are available through the static DataRepository class in the DataSource folder. The class has two static properties:
The properties are instantiated and populated in the static constructor of the class. The data for the properties come from the two XML files in the DataSource folder, which were exported from the Northwind database using the DataContractSerializer.
Please make sure to make your students aware that the static class and static properties are only used here for the sake of simplicity and this is by no means a best practice to implement data sources.
Note that the properties are actually of type List at runtime.
Note that the namespace of the DataRepository class, DataSource is already referenced in Program.cs. If you add other files, you have to add the reference to the namespace yourself.
In order to visualize the results of queries, an extension method called Dump() was implemented to the IEnumerable type. The Dump() method has the following capabilities:
Note that the namespace of the class of the extension method, Extensions is already referenced in Program.cs. If you add other files, you have to add the reference to the namespace yourself.
Please make sure to discuss with your students how LInQ query evaluation works and the inner implementation of Dump() triggers query evaluation.
##Licensing and terms, contribution and other materials
You are welcome to use this extension during your presentations, classes or courses with the limitations of the MIT license (which is not that much :) ). But use it at your own risk :) and always test your demos beforehand (especially in the case of Dump() which was not tested extensively).
If you have ideas, requests or comments, visit the Github page of the extension.

User handling is a fundamental part of a ton of web projects. This post will walk through how to customize Friends of Symfony (FOS) User attributes and forms in a Symfony 3 project.
By default FOS Users only have username, email, and password attributes. If you want to add more information like an address or phone number to your users there are several steps you’ll need to take which are described here.
The FOS User bundle also comes with some handy forms for user registration, login, and profile editing. These forms do not contain any styling information, and will not automatically incorporate any custom attributes you add to the User entity. How to overcome these obstacles is also detailed here.
Assumptions
This post will assume you have already set up some things:
- LEMP or equivalent development environment with
- global install of Composer
- Symfony 3 Project with FOS user bundle installed and setup
Expanding the User Entity
Open up src/AppBundle/Entity/User.php. The @ORM annotations tell Symfony’s default ORM, Doctrine, how to update the schema the database is built from.
Define a new class attribute, phoneNumber, including @ORM annotations to inform the database schema. Add Validator/Constraints to the use statements to define form validation using annotations as well.
Symfony validation groups allow different subsets of attributes in a class to be validated by passing the name of a group as an option to the form validator. Only attributes in the group passed to the validator will have their validation assertions checked.
The FOS User we’re extending has placed attributes into the validation groups: Registration, Profile, ResetPassword, and ChangePassword. Only the password fields need to be validated when resetting or changing the password, so phoneNumber is only assigned to the Registration and Profile validation groups.
Create Getters and Setters
Later when creating and updating Users, you will need to be able to access the phoneNumber attribute and any others we create in future. The User class will need public methods called “getters and setters”.
These methods are easy enough to type out, but it can become tedious and many IDEs will have a built in way to generate them. For example, in PHPStorm you would place your cursor in your User class after the __construct method, then from the Code menu select Generate, and then choose “Getters and Setters” from the menu that appears.
This is what your getter and setter will look like for the phoneNumber attribute:
Update the Schema:
Using the mysql shell, SequelPro, PHPMyAdmin, or another database interface of your choice, you can visually confirm that the fos_user table in your project database now contains a phone_number column.
Update User Forms
The User class has been expanded, but the registration form, edit profile form, and the view profile page will not include our new phoneNumber attribute without some additional work.
Create New Form Types
In the src/AppBundle directory, create a new folder named Form. Create two new php files in your new directory: RegistrationType.php and ProfileType.php containing a RegistrationType class and ProfileType class respectively.
Both of these new classes will be in the AppBundle namespace, extend AbstractType, and implement the methods: buildForm(), getParent(), and getBlockPrefix().
Here’s what your RegistrationType will look like when complete:
Notice how it adds phoneNumber to the FormBuilderInterface instance in buildForm().
ProfileType will be almost the same, except the class name will change, getParent() will return FOSUserBundleFormTypeProfileFormType, and getBlockPrefix() will return app_user_profile.
Update Config
To make use of the new form types you will need to add information on them to your configuration files.
Add the following under “services:” in app/config/services.yml:
In app/config/config.yml you’ll need to add registration and profile config to the end of your existing fos_user config. Once added, the whole fos_user config should look like this:
Override Templates
You’ve added the new phoneNumber attribute to the registration and edit profile forms, but it still will not appear when viewing a user’s profile.
Additionally, all the FOS User bundle forms are completely unstyled and thus are not ready to mesh with the rest of the project.
These issues are fixable using Symfony’s handy bundle template overriding and Twig template inheritance.
Create a base template.
Open up app/Resources/views/base.html.twig – the default base template for your project. The blocks defined in this template can be overridden by other twig files which extend this one, so this is a great place to put things like styles and javascript that you want to be universal to all pages in your project.
Add some content to the stylesheets block:
This brings in some basic style options from bootstrap and adds one small custom class style for use later.
Add some content to the javascripts block. This brings in some bootstrap javascript that works with bootstrap styles:
Now these styling options will be available in any twig template which starts with:
To add styles to forms automatically, open app/config/config.yml and add the form_themes option to the existing twig config:
Create overriding templates directory structure.
Incorporating third party bundles into a Symfony project is a great way to add functionality without reinventing the wheel. Visually, it’s still important for a project to present as a cohesive set of pages, and not a hodge podge of stitched together components.
This can be accomplished by leveraging Symfony’s option to override bundle templates.
To override any or all of a bundle’s templates in Symfony, create a directory inside your project’s app/Resources directory with the same name as the bundle’s main classname.
If any files and folders inside the new directory match those in the bundle’s Resources directory, the new files will be used instead of the bundle’s version.
So that you can modify the existing FOS User bundle template content rather than starting from scratch, create the following directories and copy the FOS User bundle templates ( vendor/friendsofsymfony/user-bundle/Resources/views) we want to modify into them:
create app/Resources/FOSUserBundle/views
- place a copy of layout.html.twig into the new directory
create app/Resources/FOSUserBundle/views/Profile
- place a copy of Profile/edit.html.twig into the new directory
- place a copy of Profile/show.html.twig into the new directory
- place a copy of Profile/show_content.html.twig into the new directory
create app/Resources/FOSUserBundle/views/Registration
- place a copy of Registration/register.html.twig into the new directory
create app/Resources/FOSUserBundle/views/Security
- place a copy of Security/login.html.twig into the new directory
Once the targeted vendor files have been copied into the new folders, your directory structure will look like this:
Merge the base and layout templates.
From app/Resources open up the base project template, views/base.html.twig, and the base FOS User template, FOSUserBundle/views/layout.html.twig.
There are several pieces of layout.html.twig that we might want to have throughout our site. Moving them into base.html.twig accomplishes this.
FOS User bundle’s layout includes conditional authentication text and links at the top of each FOS User bundle page. To make that content part of every project page, just inside base.html.twig’s body block, create a navbar component that contains the conditional login / logout options and greeting:
Then remove that content from layout.html.twig
After the new navbar, create a div with the “jumbotron” class you customized earlier. Inside the new div, add new “name” and “content” Twig blocks. Between those tags, copy in the messaging content from layout.html.twig
Delete that messaging content from layout.html.twig
Now that the dynamic content from layout.html.twig has been moved into the project’s base template, all it needs to do is extend that base template and state where to place the fos_user_content block. After all the other content has been removed, your template will look like this:
Update the Profile
Symfony’s Twig templates allow for multi level inheritance. Use this to create a profile.html.twig which fills in the name block we created earlier:
Open up
Profile/edit.html.twig and
Profile/show.html.twig and update them, replacing the current
extends tags with:
{% extends "@FOSUser/Profile/profile.html.twig" %}
Open up Profile/show_content.html.twig and add a line to display the new phoneNumber:
Registration and Security
Open up
Registration/register.html.twig and
Security/login.html.twig
Add and fill in the name block for each. Add a link under their included content so that a user can easily switch between the register and login forms.
The final register.html.twig will look something like:
The final login.html.twig will look something like:
Success!
Congratulations, you now have a functional, if content-free, Symfony 3 application! Check out the registration process and navbar access to login, logout, and edit profile:
Now you have custom Users! Above we expanded FOS User bundle User and forms, created a simple universal style for the project, then overrode FOS User templates to modify their content and look to match.
Using the same techniques you practiced here, you will be able to add attributes to FOS User bundle Users to suit your project’s needs, and incorporate FOS User forms and pages into any Twig templated project.
Are you building something awesome for users with Symfony? Have suggestions for Symfony howtos you’d like to see? I want to hear about it!

Allows you to interface Python and zepto crudely
Project description
pyzepto
A crude way of interfacing zepto and Python.
Installation
pip install pyzepto
Usage
I really advise against using it. It’s amazingly crude. But if you really want to do this, it’s relatively straight-forward. The main function that is exposed by this package is zepto. It takes a string of zepto code and evaluates it, returning the return value as a string.
from pyzepto import zepto zepto("(+ 1 2 3)") # => "6" zepto("(make-byte-vector 10 0)") # => "b{0 0 0 0 0 0 0 0 0 0}"
I also implemented a custom module loader for your convenience, so you can import zepto files into Python using regular import statements. What could possibly go wrong? | https://pypi.org/project/pyzepto/ | CC-MAIN-2020-10 | refinedweb | 128 | 56.15 |
Hey issue in my project in displaying time in the correct format on the required time zone.
Handling date/time when dealing with time-zones is a tedious task.
As a developer, getting date from server then converting, comparing and displaying date and time might get tricky on front-end side.
So the best solution for this is use of a library called –
Moment.js
Moment.js is a Javascript library for parsing, validating, manipulating, formatting and displaying dates and times.
It’s easy documentation also makes it the first choice for the developers.
Integrate moment.js with Angular
INSTALL
npm install moment –save # npm
yarn add moment # Yarn
Install-Package Moment.js # NuGet
spm install moment –save # spm
meteor add momentjs:moment # meteor
IMPORT
(in the component app.component.ts and in the component to be used)
import * as moment from ‘moment’;
Now you can now use Moment.js in your entire Angular app, as long as you import it into the component in which you plan to use it
Here I will show how to get local time if you have a utc date time string.
Lets say you have a UTC date-time string as 2014-02-19 05:24:32 AM and you want to convert utc time to local time then use following :
utcDateTime: any;
this.utcDateTime =“19 June 2011 13:23 “;
let local_date = moment.utc(this.utcDateTime).local().format(‘YYYY-MM-DD HH:mm:ss a’);
Output: 2011-06-19 18:53:00 pm
let local_date = moment.utc(this.utcDateTime).local().format(‘MMMM DD, LT’);
Output: June 19, 6:53 PM
There are multiple manipulation’s and formats under moment.js which can be referred to it’s documentation at this link .
we will discuss it’s detailed features further …
4 thoughts on “Manipulating Server returned dates at client Side in Angular”
Hi Kritika, if you are using moment.js just only for converting UTC time to client-side timezone, then it is really not required you can convert between them without using this (moment.js), it will even make your application heavy
Hi @sourabh , Thanks for your time , and FYI we are not just using it for conversion but for various human friendly formats and few manipulations too, it is just to demonstrate on this post we are showing the integration and conversion part of moment.js as it supports i18n (internationalization) and l10n (localization) so is best for conversion, also i’ll surely discuss it’s bundle of available options in futher posts.
@kritika that’s fine, we can have a 1to1 discussion for this

Contents
Up until now, our entire Flask application mainly resides in a single file
main2.py. That’s fine for small applications, but as the project grows it becomes difficult to manage. When we break a monolithic file into multiple files, the code in it becomes more maintainable and predictable.
Flask doesn’t impose any restrictions on how you should structure the application. However, it does provides some guidelines to make the application modular.
In this course, we will use the following application structure.
Here is the rundown of what each file and folder does:
In the rest of the lesson, we will convert our project to conform to this directory structure. We will start by creating
config.py.
Class-Based Configurations
A software project usually runs in three different environments:
- Development.
- Testing.
- Production.
As the project evolves you will encounter a need to specify different configuration options for different environment. You will also notice that no matter which environment you are in some configurations always remains the same. We can implement such a configuration system using classes.
Start off by defining default configurations in the base class and then create environment-specific classes which inherit from the base class. The environment-specific classes can override or add environment-specific configurations.
Create a new file named
config.py inside
flask_app directory and add the following code in it:
flask_app/config.py
Note that for the first time we are reading values of some configurations from the environment variables. We are also providing default values in case environment variables are not set. This method is particularly useful when you have some sensitive data that you don’t want to hardcode in the application itself.
To read configurations from a class use
from_object() method as follows:
Creating Application Package
Create a new directory
app directory inside the
flask_app directory and move all files and directories to this directory ( except
env and
migrations directories and our newly created
config.py file ). Inside the
app directory create
__init__.py file with the following code:
flask_app/app/__init__.py
The
__init__.py creates the application instance and initializes extensions. If
FLASK_ENV environment variable is not set the Flask application will run in the debug mode ( i.e
app.debug = True ). To put the application in production mode set the
FLASK_ENV environment variable to
config.ProductionConfig.
After initializing extensions, the
import statement in line 21, imports all the views. This is necessary to connect the application instance to the view functions, otherwise, Flask will not be aware of your view functions.
Rename
main2.py file to
views.py and update it so that it only contains routes and view functions. Here is the complete code of updated
views.py file.
flask_app/app/views.py
The
views.py file now only contains view functions. We have moved the code for models, form classes and utility functions to their respective files, as follows:
flask_app/app/models.py
flask_app/app/forms.py
flask_app/app/utils.py
Finally, to launch the application add the following code to
runner.py file:
flask_app/runner.py
The
runner.py is the entry point of our project. The file starts by creating an instance of
Manager() object. It then defines
make_shell_context() function. The objects returned by
make_shell_context() function will be available inside the shell without explicit import statements. At last, the
run() method on the
Manager instance is called to start the server.
Import Flow
We have created quite a few files in this lesson and it is very easy to lose track of which file does what and the order in which files are executed. To make things clear this section explains shows how everything works together.
Things start with the execution of
runner.py file. The second line of
runner.py file imports
app and
db from the
app package. When Python interpreter encounters this line, program control transfers to
__init__.py to start its execution. In line 7,
__init__.py imports the
config module which transfers the program control to
config.py. When the execution of
config.py completes the program control again comes back to
__init__.py. In line 21,
__init__.py file imports
views module which transfers the program control to
views.py. The first line of
views.py again imports application instance
app from the
app package. The application instance
app is already in the memory so it will not be imported again. In line 4, 5 and 6,
views.py imports models, forms and
send_mail function respectively which transfers the program control temporarily to their respective files in turn. When the execution of
views.py finishes the program control comes back to
__init__.py. This completes the execution of
__init__.py. The program control comes back to
runner.py and starts the execution of the statement in line 3.
The third line of
runner.py imports the classes defined in the
models.py module. Since models are already available from
views.py, the
models.py file will not be executed again.
Since we are running
runner.py as the main module, the condition in line 17 evaluates to
True and
manager.run() starts the application.
Running Project
We are now ready to run our project. In the terminal enter the following command to start the server.
If
FLASK_ENV environment variable is not set, the preceding command will start the application in the debug mode. Navigate to and you should see the home page which currently looks like this:
Browse the remaining pages of the application to make sure everything is working as expected.
Our application is now very flexible. It can pick up a completely different set of configurations just by reading an environment variable. For example, let’s say we want to put our site in production mode. To do so, simply create an environment variable
FLASK_ENV with the value
config.ProductionConfig.
In the terminal, enter the following command to create
FLASK_ENV environment variable:
This command creates an environment variable in Linux and Mac OS. Window user can use the following command:
Run the application again.
Now our application is running in production mode. At this point, if Python code raises an exception you will see a 500 Internal Server Error instead of a stack trace.
Because we are still in development, we have to delete
FLASK_ENV environment variable. The
FLASK_ENV will be deleted automatically as soon as you close the terminal. To manually delete it enter the following command:
Window users can use this command:
Our project is in much better shape. Now things are organized in a much more predictable way than it was possible before. The technique devised here is useful for small to medium-sized projects. However, Flask has some more tricks under its sleeve which can help you to become more productive.
Blueprints
Blueprints are yet another way to organize the application. Blueprints provide separation of concerns at the level of views. Just like a Flask application, a Blueprint can have its own views, static files, and templates. We can also map blueprints with their own URIs. For example, let’s say we are working on a blog and its admin panel. A blueprint for a blog would contain view function, templates and static assets specific to the blog only. Whereas the blueprint for admin panel would contain views, static files, and templates specific to the admin panel. Blueprints can be implemented either by using a module or a package.
It’s time to add a blueprint to our project.
Creating Blueprint
Create an directory named
main inside the
flask_app/app directory and move
views.py and
forms.py to this directory. Inside the
main directory create
__init__.py file with the following code:
flask_app/app/main/__init__.py
We are creating blueprint object using the
Blueprint class. The
Blueprint() constructor takes two arguments, the blueprint name and the name of the package where blueprint is located; for most applications passing
__name__ to it will suffice.
By default, views functions in the blueprint will look for templates and static assets in the application’s
templates and
static directories respectively.
We can change that by specifying the location of templates and static assets while creating
Blueprint object as follows:
In this case, Flask will look for templates and static assets in the
templates_dir and
static_dir directories inside the blueprint package.
The template path added by a blueprint has lower priority than the application’s templates directory. That means if you have two templates of the same name in
templates_dir and
templates directories, Flask will use the template from the
templates directory.
The following are some noteworthy points to remember about the blueprints:
1. When using blueprints the routes are defined using the
route decorator of the blueprint object rather than the application instance (
app ).
2. To create URLs when using blueprints you have to prefix the endpoint with the name of the blueprint and a dot (
.). This is true whether you are creating URLs in the Python code or in templates. For example:
This will return the URL of the
index route of the
main blueprint.
The name of the blueprint can be omitted, in case you are in the same blueprint that you want to create URL for. For example:
This will return the URL of the
index route of the
main blueprint assuming you are in the view function or template of the
main blueprint.
To accommodate the changes we have to we have to update
import statements,
url_for() calls and routes in
views.py file. Here is the updated version of
views.py file.
flask_app/app/main/views.py
Notice that throughout the
views.py file, we are creating URLs without specifying the blueprint name because we are inside the same blueprint for which we are creating URL for.
Also update the
url_for() call in
admin.html as follows:
flask_app/app/templates/admin.html
The view functions in
views.py are now associated with the
main blueprint. Next, we have to register the blueprint on the Flask application. Open
app/__init__.py and modify it as follows: (changes are highlighted):
flask_app/app/__init__.py
The
register_blueprint() method of the application instance is used to register blueprint. We can register multiple blueprints by calling
register_blueprint() for each blueprint. Notice that in line 11, we are assigning
main.login to the
login_manager.login_view. In this case, it is necessary to specify the blueprint name otherwise Flask wouldn’t be able to tell which blueprint you are referring to.
At this point, the application structure should look like this:
The Application Factory
We are already using packages and blueprints in our application. We can further improve our app by delegating the task of instantiating application instance to the Application Factory. Application Factory is simply a function which creates an object.
So what do we get by doing this:
- It makes testing easier because we can create application instance with different settings.
- We can run multiple instances of the same application in the same process. This is handy when you have load balancers distributing traffic across different servers.
Let’s update
app/__init__.py to implement an application factory as follows (changes are highlighted):
flask_app/app/__init__.py
We have delegated the task of creating application instance to the
create_app() function. The
create_app() function takes a single argument named
config and returns an application instance.
Application factory separates the instantiation of the extensions from their configurations. The instantiation occurs before
create_app() is called and configuration occurs inside the
create_app() function using the
init_app() method.
Next, update
runner.py to use applicaton factory as follows:
flask_app/runner.py
It is important to note that when using application factories, we no longer have access to the application instance in the blueprint at the import time. To access application inside a blueprint use
current_app proxy from the
flask package. Let’s update our project to use
current_app variable as follows:
flask_app/app/main/views.py
flask_app/app/utils.py
Now you should have a have a solid understanding of Flask, its different components and how everything fits together. Believe it or not, we have explored quite a lot. In the next part of this course, we will use what we have learned to create a Delicious clone named Flask-Marks. Delicious is a social bookmarking site launched in 2003. In 2017, it was acquired by Pinboard and since then it is running in read-only mode. Flip the page and let’s get started.

Hi,
Thanks for sharing this. can you please explain line 2 in file flask_app/app/main/views.py. How the import works here? And how can I test it tat this line works? Please let me know
In line 2 . represent current directory.
Please help. I’m having trouble with Blueprints static folder on a site that has one main domain with two sub-domains. The sub-domain static_folder defaults to the main.

A Simple Machine Learning Implementation to Predict Linear Algebra in Python
This article was published as a part of the Data Science Blogathon.
Machine learning is used to solve the problem in which the rules to get the desired output are too hard (almost impossible) to mapped manually by a human. So, instead of giving the rules to a computer, we feed the desired output and let the computer learn (guess) the pattern to figure out the rules by itself.
In this article, we will create a simple machine learning implementation in Python using the TensorFlow library.
The real-world problems are more complex than this and require advanced-level algorithms to derive better and crisp insights from data. Check out our Certified AI & ML BlackBelt Accelerate program.
The model we will build expected to be able to find this formula:
y = 2x + 4
We will not write that formula into the program. Instead, we will give several input samples (x), and outputs from the given input.
Creating the model architecture
This is the model architecture we want to build. It’s a very simple model.
and this is how it looks in the code:
import tensorflow as tf model = tf.keras.Sequential() model.add(tf.keras.layers.Dense(units=1, input_shape=[1])) model.compile(optimizer='sgd', loss='mean_squared_error')
The input_shape argument defines the number of input neurons and the units argument defines the number of output neurons. The loss argument is to define the loss function. The loss function is a function to measure how bad our current output compared to the target output. We also define the optimizer for our model. The optimizer is the algorithm that helps us find the best weight. Here we are using Stochastic gradient descent (SGD). The best weight is the weight that gives us a minimum loss.
We can print our model to the console to check the parameters of the model compiled using this line of code.
model.summary()
There are two trainable parameters listed. Because we only have one neuron in the input layer and one neuron in the output layer, therefore, we only have one weight to be trained. Another parameter is a bias neuron.
Provide the dataset
The input data will be stored on the x variable and the output data on the y variable. Here we only have ten data for each. In machine learning, the output of training data is called a label.
import numpy as np x = np.array([0, 4, 8, 6, 3, 2, 9, 5, 7, 1]) y = np.array([4, 12, 20, 16, 10, 8, 22, 14, 18, 6])
Train the model
Now we are ready to train our model. The epoch is 1000, which means that the algorithm will train on the data 1000 times. Thousand seems too big for epochs, but don’t worry, because our model is simple, it only takes a second to finish.
model.fit(x, y, epochs=1000, verbose=0)
Predict the unseen data
The main goal of our model is to be able to predict the unseen data. This is what distinguishes machine learning from other computer programs. It has the ability to adapt to unseen input data.
prediction = model.predict([12])
print(prediction)
The output is:
[[28.010925]]
The model never sees input 12 in the training phase, and the model also never told that the formula to calculate the output is y = 2x + 4. However, the machine learning model successfully predicts the output from the given input.
The problem used in this article can also be solved without machine learning. It is even easier without machine learning. However, the main goal of this article is for us to successfully build a simple machine learning model and to understand how it actually works.
What’s next
- Train the model with a different dataset
- Build a more complex model
- Play with an MNIST dataset

.
I.
After done mapping for my entities I wanted to test the basic CRUD operations. I stuck with a problem of inserting a data to tables in many to many relation, so I wanted to look at the generated sql by the NHibernate to find out, what is really generated to investigate the problem in my mappings. The NHibernate have a property called show-sql to show the generated statements.
I enabled it in the config:
var configure = new Configuration();
configure.SessionFactoryName("BuildIt");
configure.DataBaseIntegration(db =>
{
//...
db.LogFormattedSql = true;
db.LogSqlInConsole = true;
db.AutoCommentSql = true;
});
To set the output to the build-in console in Visual Studio I used a Maciej Aniserowicz solution.
His post is all in polish language, so a little clarification.
Every line of text send to System.Diagnostics.Debug.WriteLine(..) is going to the VS console. So Maciej added a simple wrapper for it:
public class CustomDebugWriter : TextWriter
{
public override void WriteLine(string value)
{
Debug.WriteLine(value);
base.WriteLine(value);
}
public override void Write(string value)
{
Debug.Write(value);
base.Write(value);
}
public override Encoding Encoding
{
get { return Encoding.UTF8; }
}
}
At the beginning of the application there must be placed a
#if DEBUG
Console.SetOut(new CustomDebugWriter());
#endif
to set the new class responsible for operating on the output set to the console.
Running that code results ALMOST in that way I wanted to. Generating sql is placed in the VS console, but only for sql SELECT statements and I didn't know why (really I still don't ;).
So I decided to use the log4net logging library to get the result in the file at least. After adding a reference to this library and set the framework target there must be done two things. One is placed in app.config/web.config the configuration for the library. I found somewhere a little config which work ok:
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
</configSections>
<log4net>
<appender name="NHibernateFileLog" type="log4net.Appender.FileAppender">
<file value="logs/nhibernate.txt"/>
<appendToFile value="false"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%d{HH:mm:ss.fff} [%t] %-5p %c - %m%n"/>
</layout>
</appender>
<logger name="NHibernate.SQL" additivity="false">
<level value="DEBUG"/>
<appender-ref
</logger>
</log4net>
And second is to add at the beginning of the application a single line
log4net.Config.XmlConfigurator.Configure();
In this moment we have all, including INSERT and UPDATE statements in the logs/nhibernate.txt file. But this is not all.
When we now check the VS console, we can see that we have there all the logs sended to the file, that means the INSERT/SELECT/UPDATE statements, so using this log file is useless :)
Don't know, why after added and configured the log4net library is started to work as I expected, but I'm glat it did :)
I?
I'm diving in the NHibernate 3.2 mapping by code recently.
I throught that, mapping a string with specific max length to the appropriate database table will be easy, but it wasn't. I lost some time to figure it out.
At the beginning I mapped a string field in that way
Property<string>(x => x.Title, x => x.Length(Int32.MaxValue));
After generating the tables in database with my schema, unfortunatelly
this field was generated as a nvarchar(255) and I didn't know why.
Property<string>(x => x.Title, x => x.Length(Int32.MaxValue));
After generating the tables in database with my schema,
We can deal with it in few ways.
1. We can manually set the length to the value greater than 4001 (link)
Property<string>(x => x.Title, x => x.Length(4002));
2. We can set the type in this way:
Property<string>(x => x.Title, x => x.Length(4002));
Property(x => x.Title, x => x.Type(NHibernateUtil.StringClob))
3. Or we can set manually the sql type:
Property<string>(x => x.Title, x => x.Column(z => z.SqlType("nvarchar(max)")));)); | http://geekswithblogs.net/lszk/archive/2011/07.aspx | crawl-003 | refinedweb | 655 | 51.44 |

Lets face it, there are over 6,000 modules there, and I for one
would love to search on "foo" and sort by "reputation" (to borrow
a PM phrase).
There is/was something in the works. CPANTS (Comprehensive Perl Archive Network Testing Service) has been talked about for some time and work appears to have begun on it.
If you want to help, there's a developer list you can subscribe to here.
As part of this there is meant to be a karma rating for authors and modules.
At YAPC::Eu::2001 I signed up for a working group to implement a karma. OeufMayo and BooK were also involved. I think that we all felt that the PerlMonks system could be used in some way. However, I haven't written any code and judging by the mailing list no-one else has either.
Nevertheless, it is a good idea and it should be followed through.
Does anyone have any opinions about the suitablity of the Slash, PerlMonks or Everything engines for this task?

And then CPAN will turn into a great big vote-whoring exercise and before you know it, someone will write Natalie::Portman and Hot::Grits.
counting downloads wouldn't work, though, because of all those pesky mirrors
This is true if FTP downloads are counted. However CPAN.pm and PPM could be modified to notify a central server every time a user installs or updates a module. Of course, not everyone uses CPAN.pm or PPM.
Also, this may be considered undesirable from a privacy standpoint.
I don't think counting downloads alone in any fashion is going to provide the kind of info to be really helpful. However, it would be good to have it along side a 'vote' based system, so that you could tell what percentage of the people that downloaded it rated it well.

If that's any help once upon a time I designed a Module Review Report. It might be a starting point to design an application that would let people give their opinion on modules.
A general index listing categorized modules (that's easy, the namespace provides a convenient category) and the summary could link to the detailed report (which could be sorted on the various fields).
BTW I think it is important that comment authors be listed, as it prevents "ballot stuffing" and gives readers a way to evaluate the credibility of the rating.
At the moment the review section is... just an idea, there is no code whatsoever to support it. I would think that in order to work it would have to be part of PerlMonks, just so users can be authenticated by the site.
I (or anybody with half a clue and more time on their hands!) can write a quick proto, just to demonstrate the concept and get the UI right, but then the maintainers would have to integrate it in the site.
Authentication-wise, we can can always have our own list of users, although admittedly a Perl Monks tie-in would be great.

If for some reason, you end up with a shapefile that is missing the shx file then most software is going to complain and refuse to deal with it. The shapefile spec requires, at a minimum, that you have an shp, shx, and dbf file to have a complete file. However this requirement is not a technical requirement and a lot of people seem to be confused about that.
The shx file is a trivial index file that provides fixed-length records pointing to the byte offsets of records in the shp file only. It does not connect the shp file and dbf file in any way nor does it contain any sort of record number. There are no record numbers stored in any of the three standard files which is often a point of confusion. The software reading a shapefile has to count the number of records read to determine the record id (geometry and attributes). If you wrote a program to randomly select a record from a shapefile there is no way to tell what the record number is by the record contents.
The purpose of the shx file is to provide faster access to a particular record in a shapefile without storing the entire record set of the shp and dbf files in memory. The header of the shx file is 100 bytes long. Each record is 8 bytes long. So if I want to access record 3, I know that 2*8 = 16 and I can jump to byte 100+16=116 in the shx file, read the 8-byte record to get the offset and record length within the shp file, and then jump straight to that location in the shp file.
While the shx file is convienient it isn't necessary. Most software balks if it is not there though. However pyshp handles it gracefully. If the shx index is there it is used for record access, if not then pyshp reads through the shp records into memory and handles the records as a python list.
Sometimes shx files become corrputed or go missing. You can build a new shx index using pyshp. It's kind of a hack but still very simple. In the following example we build an index file for a point shapefile named "myshape" that has two files: "myshape.shp" and "myshape.dbf"
# Build a new shx index file import shapefile # Explicitly name the shp and dbf file objects # so pyshp ignores the missing/corrupt shx myshp = open("myshape.shp", "rb") mydbf = open("myshape("myshape")
If the shx file is missing it will be created. If it's corrupt it will be overwritten. So the moral of the story is because shapefiles consist of multiple files, it is actually a robust format. The data in the individual files can usually be accessed in isolation from the other files despite what the standard requires - assuming the software you're using is willing to cooperate.
had an issue with auto cad where i would use map export to create my shape file, then when i import the file into another drawing to check that it did it correctly i would get an error about the dbf and shp files not matching, your software corrected it, thanks very much!
oops, not the shp file, the error said the dbf is corrupt or does not have same number of objects as the shx file, run your program and it works, pretty simple, I wonder why its not working properly though, any ideas?
This is just what I needed! I modified it slightly into a standalone module/program so I could fix several shapefiles which were missing their SHX.
(Sorry, indentations don't show up.... makes it harder to use this sample code!)
def RebuildShx(path):
'''This code based on'''
print(path)
# Build a new shx index file
import shapefile
# Explicitly name the shp and dbf file objects
# so pyshp ignores the missing/corrupt shx
myshp = open(path+".shp", "rb")
mydbf = open(path+"(path+"_fixed")

Hi,
I'm trying to display a PDF saved in local on my iOS App.
Here's my code, it works with a Web URL (example :) but not with a local url (example :
).
Here's my C# code :
public class WebViewDoc : ContentPage { public WebViewDoc (String filename) { String documentsPath = Environment.GetFolderPath (Environment.SpecialFolder.MyDocuments); String fullPath = Path.Combine (documentsPath, filename); // Result : var browser = new WebView (); browser.Source = @fullPath; // Works if replacing by a web url Content = browser; } }
Did someone have a solution ?
Thank you,
Simon
have you tried using a "file://" scheme with the url?
Hi @JasonAwbrey ,
Yes, and still not ok.
Here's the code to save the file on my app, maybe the problems come from it?
@SimonDellise , @JasonAwbrey
I am currently having the same issue. There are plenty of example for Android but not for iOS. I tried using success. I am wondering if it is a simulator issue or something else...
Hi @hvaughan , I've used this for iOS :
The problem was simply the spaces in the file name ... So I replaced all of them by an underscore ( _ ) and now, it works fine !
The webview code :
I hope this will help you.
@SimonDellise
Awesome! Thank you. I think that solved it for me. I also was not using
.ApplicationData.
One more question if you don't mind, for Android, when you open using another application (such as adobe reader), are you handling the case when the user does not have any PDF viewer installed? I found
PDF.js(link below), but just wanted to see if you had a better alternative. Thanks again.
@hvaughan You're welcome
Unfortunately, I haven't found any better solution at your question. I think PDF.js is a great alternative to the native app. | https://forums.xamarin.com/discussion/comment/128796/ | CC-MAIN-2020-24 | refinedweb | 294 | 68.16 |
Elmo's World
From Uncyclopedia, the content-free encyclopedia
Elmo greeting his next victim to his world.
“I only tickled him where he wanted it.”
Elmo's World is a place of pure evil that man greatly fears. It is a dark and gruesome place ruled by a mass murderer named Elmo. The world consists of burning brimstone and suffering people, and is filled with the screams of the children who are its only permanent residents. This amuses the sinister Elmo, and makes him very happy to be the king. Those who enter this horrible world never return (except for blithering cowards), or if they do, they die within the next twenty seconds of escape.
edit Elmo
Elmo moments before his first kill.
The story of Elmo's World began with the little monster named Elmo. Elmo was originally constructed as a toy for little children from Fisher-Price. There were many types of Elmos, some played patty cake and others were ticklish. Also, because children loved expensive and interactive toys, all the Elmos were a success. So it wasn't long before there came the plan to make an Elmo that knew children's names. Fisher-Price crowned this as their grand master plan, and they would even jack up the price even more than all previous Elmos. However Fisher-Price was facing a tight economic budget, so to save money, they decided to use thread from old materials that no one ever used anymore. One of these Elmo toys was stitched together from the the very thread that made up the coat of Jack the Ripper, and thus the spirit of the evil killer possessed the toy.
Elmo about to claim another life.
The toy was later purchased by a man who wanted to be a ventriloquist and since he wasn't very good at thrusting his voice, a talking doll was just what he needed to get his career going. At first, signs of possession went unnoticed. But soon the man's family started to worry when the doll threatened to kill their son, Fisher-Price simply passed it off as a malfunction. Two nights after the threat, the doll made its first kill. The man was doing a show one night with Elmo and was asking Elmo a lot of questions that annoyed the living hell out of him. Then he finally asked Elmo if he liked him, to which the doll responded by literally putting him in the spot light.
Elmo then started his career as a mass murderer. He continued this career for years, and soon his blue fur turned red after being stained with so much blood. Due to being possessed by Jack the Ripper, Elmo usually targeted women that he came across, though he would happily kill their husbands if they ever tried to stop him...which they all failed miserably.
However, he soon grew fascinated with the children that he also encountered and they soon became a major subject of his kills. The kills garnered much controversy around Fisher-Price who had accidentally brought this monster into the world. But Fisher-Price didn't mind, they were the subject of many newspaper articles and media attention, they ate this all up. There were many attempts by complete and utterly stupid people (including the aforementioned husbands) to put Elmo down, but all who tried to stop him met a bloody and horrible fate.
At one point, Elmo devised a horrible plan to kill Mr. Hooper, simply because he forgot to pay him once when he decided to work for him as a grocery bagger. He murdered Mr. Hooper's wife along with her boyfriend Jim Henson by using a shotgun while they were making out in Hooper's bedroom. Since the police were stupid, they magically assumed that Mr. Hooper had murdered his wife rather than Elmo (even though he had written with his crayon "Elmo Wuz Here" on the wall) and he was sentenced to be executed by the electric chair. Mr. Hooper tried to escape from prison using a sewer pipe, but Elmo thwarted his attempt by using his toilet to take a massive diarrhea dump, causing him to nearly drown in the Muppet's foul excrement.
During his execution, Elmo swiped the sponge that was needed to give Mr. Hooper a merciful execution while the executioner was off to take a bathroom break, causing him to die a horrible and painful death. He immediately giggled like a schoolgirl.
edit The Coming of Elmo's World
Elmo in his apartment on Sesame Street.
After years of running, Elmo was eventually caught by the police after they lured him into a pool of glue (telling him it was ice cream). Elmo was then forced to wear a strait jacket, was strapped to a operating table, and was then gagged to make sure he could not escape. Even so, the police could barely contain their prisoner, for Elmo was too psychotic and dangerous to keep subdued. Elmo was then placed in a jail cell without food and water for five weeks, during which he almost managed to escape and murdered several guards. After Elmo finally became too weak to move, they sent him to Hell after he was gunned down by Samuel L. Jackson (the only man with enough power to kill him, except for maybe Chuck Norris). Upon entering Hell, Elmo was immediately put through much torture and despair for his hideous atrocities.
Through his agony, Elmo was filled with rage and eventually challenged Satan himself for ownership of Hell. Now one would ask, what kind of idiot would risk his own kingdom when there is no need to do so? But unfortunately for Satan, he had a very big ego that forced him to do so. Elmo faced Satan in a game that he had no hope of ever cheating (let alone winning) at, a christian version of the game of Life. Elmo was actually skilled at cheating at this game and cheated his way to victory.
Upon winning the game, Elmo took over Hell and enslaved Satan himself. Elmo then brought Hell to the surface... in an apartment building on a place called Sesame Street. This place was full of cute and innocent residence, so none would suspect that Elmo's new world would be located here. Indeed, on the surface, it was a perfectly normal building. Inside the building...well...
After his new set up, Elmo lured innocent children into his world using candy and happy giggles, where they would be condemned to an eternity of torture that amused the insane Elmo. Each day Elmo thought of a different torture (usually involving a set of crayons), and his victims were forced to endure that torture until they were driven completely insane, much like Elmo himself. Elmo would start things off by showing his victims what the torture would be like, using his assistant, The Fish You Flushed a Few Years Ago. Satan himself was also used by Elmo to demonstrate these tortures, he was dressed in a bow tie and suit and was given the name Mr. Satan. He was then forced to show Elmo and his victims examples of the type of torture Elmo was thinking about.
edit End
Elmo's World met its end when Satan finally snapped his last nerve control cell. It happened one day, while Elmo was thinking of an extremely bad torture and ordered Satan to drop his pants in front of all the children. Satan refused to do so and Elmo started to whip him. He then ordered him again and again, but Satan refused and continued to get whipped. Then after the eighteenth whip, Satan finally snapped and unleashed all the hidden power he had kept contained within him for centuries, power that would force you to scream, "HOLY SHIT... that is some colossal power." This uncontrollable power broke Satan free of his chains and severely damaged Elmo's World. After the power finally simmered down, Elmo and his world were left severely injured. Satan then dragged the world and Elmo back underground. Elmo was then subject to an eternity of torture beyond imagination. | http://uncyclopedia.wikia.com/wiki/Elmo%27s_World | CC-MAIN-2017-26 | refinedweb | 1,364 | 70.23 |
Before Netscape, when Mosaic ruled the Web and people needed a straightforward way to exchange information between client and server, the Common Gateway Interface (CGI) was born. CGI applications (usually called scripts) run on the server side. A user initiates a request via HTTP and optionally transmits information, which is handed off to the CGI script. The script processes the information and packages a reply, which the server sends to the user.
The Need for Servlets
When CGI scripts were first developed, they were often written in C or Perl. C had the advantage of speed, while Perl was cross-platform. Both, however, suffered from the overhead needed to fork a new process each time the Web server needed the CGI script. The Apache Web server mitigates that penalty with modules like mod_perl, but Sun Microsystems came up with a better alternative: the Java servlet.
A servlet is just a regular Java class that implements the interface javax. servlet.Servlet as defined by the Java Servlet Specification (). Servlets run in a separate container, which runs a Java Virtual Machine. The JVM then executes the servlet as a thread.
A typical setup uses Apache as the Web server and Tomcat as the servlet container. Because the container is persistent, there is no overhead associated with starting a JVM for each servlet. (For more on setting up Tomcat, see the October 2001 article “Hangin’ With Tomcat” at.)
Further, the container can keep track of information between requests. HTTP offers no inherent means of doing this, so the Java servlet technology offers a convenient way to remember the state of a client/server session. Figure One shows the cycle of a request/response transaction: information flows from the Web client to the servlet, through the servlet container, and back.
Servlet Basics
A common situation well suited to Java servlets is the shopping cart. The client initiates a request, but most of the transaction processing takes place at the server, which must remember what else the client did this session. Java servlets refer to the saved session information as attributes.
Servlets typically interact with the user through standard HTML markup (just like a CGI script would), presenting a form to the user, who fills in the blanks. Under the hood, each form element (text, radio button, etc.) is given a name in the HTML form, and when the user presses the Submit button, that information is bundled up and transmitted to the Web server as a series of name/value pairs. The server then passes the request to the servlet container, which presents it as an HttpServletRequest object to the servlet. When the servlet returns outputs, it uses an HttpServlet Response object. The container presents the information to the Web server, which in turn sends it to the user.
Servlets at Work
The SessionServlet in Listing One (available at) demonstrates these concepts. It creates a session when it is first invoked and presents a form that allows you to add and remove attributes (see Figure Two).

To add an attribute, type a name to identify it and a value in the corresponding box and click the “add” button. To remove an attribute, type its name and click the “remove” button. Each time the screen is refreshed the servlet displays all the attributes currently stored in the session. If you visit another address and browse the servlet again later, you will see that the session is still active and the attributes are still there.
The SessionServlet inner working is pretty straightforward. In order to handle HTTP requests, all you need to do is extend the class javax.servlet.http. HttpServlet and override the appropriate methods, listed in Table One.
Table One: Important HttpServlet Methods
The methods doGet (lines 8 through 13) and doPost (lines 15 through 20) receive objects that represent both the request and the response. In this way, they actually perform the work of SessionServlet.
The request is handled by the method handleRequest(), which is called by both the doGet() and doPost() methods. This kind of arrangement is common practice, since it allows the servlet to transparently handle both GET and POST HTTP requests.
The first thing handleRequest() does is get the current session using the method getSession() of the request received (line 26). A new session is created by getsession() if this is the first time the servlet has been called by the client.
The method getSession() of the HttpServletRequest interface creates and returns an HttpSession object where you can store any attributes between requests. The methods associated with the HttpSession object are listed in Table Two.
Table Two: HttpSession API
Once created, the HttpSession object is associated with all requests from the same client to the same Web application (and can be retrieved using the same get Session() method), until it is destroyed. All the low-level details are managed by the servlet container.
The method processRequest() is called in line 27 to actually process the request. All data from the form are made available to the servlet through the appropriate API, which provides several convenient methods to get the request’s parameters. These are shown in Table Three. Once parameters are received, the servlet processes them and can optionally store them as session attributes. It can also retrieve attributes that have already been stored from previous requests in the session.
Table Three: Getting Parameters From the HttpServletRequest
The processRequest() method gets the text typed into the form fields (InputName and InputValue) in lines 41 and 42, and the name of the button clicked (RemoveButton or AddButton). It then adds or removes the attribute in lines 43 through 46.
Once processing is complete, the information is presented through the interface HttpServletResponse (see Table Four). There are methods to set the headers and body of the response, send back errors or redirect the request. In order to send back a normal response, all you need to do is set the MIME type, get a suitable character or binary stream and write the data.
Table Four: Sending an HttpServletResponse
You set the MIME type of the response you are sending back with the setContentType method. The most common case is “text/html” when you are returning an HTML page, but setting the MIME type and using the appropriate stream lets you return any type of data.
In line 28, the handleRequest() method sets the content type of the response to text/html. It gets a text stream in line 29 and outputs the actual page in lines 30 through 35, with the help from both the outputForm() and outputSession() methods.
The method outputForm() in lines 49 through 57 outputs the form used to interact with the user. This is where parameters are named InputName and InputValue. The associated values will be those filled in by the user. The method outputSession() in lines 59 through 68 outputs all attributes currently stored in the session. In line 62, the getAttributeNames() method of the session is used to iterate over all attributes.
After It’s Written
All servlets must be part of a Web application as defined by the Servlet Specification. This includes a set of HTML pages, servlets, JSP pages, classes, and other resources. These conform to a certain directory structure and require a special file, web.xml, which configures security constraints, initial parameters, and the like. Tomcat requires that the web.xml file exist, but if the file provides no parameters, Tomcat uses default values.
In order to get our ServletSession example running under Tomcat, follow the steps below.
1. Compile the example:
2. Deploy it into Tomcat:
Once the servlet is deployed, you can see it in action by browsing the address.
Exploring Further
Java servlets are natural replacements for CGI applications. They are easier to develop and offer better performance. Servlets are a good choice when your application has moderate to complex logic or when you need to return data other than HTML pages, especially binary data.
The disadvantage of Java Servlets is that they don’t provide, by default, a good separation of program logic and presentation, since statements that output HTML are intermixed with the application logic, making maintenance difficult. One solution to that problem is the Velocity template engine, a Jakarta project ().
There’s a wealth of information available for your next steps. A good starting point is the documentation that comes with Tomcat, which shows you how to develop, organize, and deploy Web applications. | http://www.linux-mag.com/id/1031/ | CC-MAIN-2017-43 | refinedweb | 1,691 | 56.55 |
Route
This is what make a single page app do not refresh.
Quick Start
It is a big topic, and here I want to make it as quick as possible to read.
- Install
react-router,
react-router-domto your project by
npm install --save react-router react-router-dom
import {BrowserRouter} from “react-router-dom”;in your App.js
- Wrap your application whole App inside <BrowserRouter></BrowserRouter>
<BrowserRouter> <div className="App"> ... </div> </BrowserRouter>
import {NavLink, Route, Link, Switch} from “react-router-dom”;or any combination of those in your container component.
- Can create the <Link> or <NavLink> to the container class like:
<nav> <ul> <li><NavLink to={"/"} exact activeClassName={"my-active"}>Home</NavLink></li> <li><NavLink to={"/post"} activeClassName={"my-active"}>New Post</NavLink></li> </ul> </nav>
- To display the components based on the URL route, you can do:
<Route path="/" exact component={Posts}/> <Switch> <Route path="/post/:id" exact component={FullPost}/> <Route path="/post" exact component={NewPost}/> </Switch>
Link, NavLink
If we do a <a href=“…”>xxx</a> for a link, the page will refresh, so we need to use
<Link>xxx</Link> or
<NavLink>xxx</NavLink> to replace it. Details here:
They have the following main props:
- to
- The URL to go to
- exact
- Will use this route only if the URL match exactly as the one in
to
- activeClassName
- The class name add to this block if it is active, mostly of CSS make up
Example: Go to exact path / if this Home link is click, and if it is active, it should have a css class named my-active
... <li><NavLink to={"/"} exact activeClassName={"my-active"}>Home</NavLink></li> ...
Route
If the url route is match to the path props, show the component, or render the JSX. Note that any URL match the path will be loaded.
<Route path="/" exact component={Posts}/> <Route path="/" exact render={()=><div>Demo1</div>}/> <Route path="/" exact> Demo2 </Route>
Switch
If you only need the very first route to be load on match. You can use Switch.
<Switch> <Route path="/:id" exact component={Posts}/> <Route path="/" exact render={()=><div>Demo1</div>}/> </Switch

}You can see how quickly the lines with a StringBuilder local variable are completed, and how much slower multiple += calls on a String are. You can time it with some System class methods.
I tried that program; I could see the delay after “Stringbuilder without size”, but not after “Stringbuilder with size”, because it was so fast. But “Using +=” has been sitting running for over 10 minutes and not completed.

Let's say you want to implement a rough little search for an application without a proper backend. You could do it through lunr and generate a static search index to serve.
The problem is that the index can be sizable depending on the amount of the content. The good thing is that you don't need the search index straight from the start. You can do something smarter instead. You can start loading the index when the user selects a search field.
Doing this defers the loading and moves it to a place where it's more acceptable for performance. The initial search is going to be slower than the subsequent ones, and you should display a loading indicator. But that's fine from the user's point of view. Webpack's Code Splitting feature allows doing this.
To implement code splitting, you need to decide where to put the split point, put it there, and then handle the
Promise:
import("./asset").then(asset => ...).catch(err => ...)
The beautiful thing is that this gives error handling in case something goes wrong (network is down, etc.) and gives a chance to recover. You can also use
Promise based utilities like
Promise.all for composing more complicated queries.
In this case, you need to detect when the user selects the search element, load the data unless it has been loaded already, and then execute search logic against it. Consider the React implementation below:
App.js
import React from "react"; const App = () => { const [index, setIndex] = React.useState(null); const [value, setValue] = React.useState(""); const [lines, setLines] = React.useState([]); const [results, setResults] = React.useState([]); const search = (lines, index, query) => index.search(query.trim()).map((match) => lines[match.ref]); const onChange = ({ target: { value } }) => { setValue(value); // Search against lines and index if they exist if (lines && index) { setResults(search(lines, index, value)); return; } // If the index doesn't exist, it has to be set it up. // You could show loading indicator here as loading might // take a while depending on the size of the index. loadIndex() .then(({ index, lines }) => { setIndex(index); setLines(lines); setResults(search(lines, index, value)); }) .catch((err) => console.error(err)); }; return ( <div className="app-container"> <div className="search-container"> <label>Search against README:</label> <input type="text" value={value} onChange={onChange} /> </div> <div className="results-container"> <Results results={results} /> </div> </div> ); }; const Results = ({ results }) => { if (results.length) { return ( <ul> {results.map((result, i) => ( <li key={i}>{result}</li> ))} </ul> ); } return <span>No results</span>; }; function loadIndex() { // Here's the magic. Set up `import` to tell Webpack // to split here and load our search index dynamically. // // Shim Promise.all for older browsers and Internet Explorer! return Promise.all([ import("lunr"), import("../search_index.json"), ]).then(([{ Index }, { index, lines }]) => ({ index: Index.load(index), lines, })); }
In the example, webpack detects the
import statically. It can generate a separate bundle based on this split point. Given it relies on static analysis, you cannot generalize
loadIndex in this case and pass the search index path as a parameter.
Beyond search, the approach can be used with routers too. As the user enters a route, you can load the dependencies the resulting view needs. Alternately, you can start loading dependencies as the user scrolls a page and gets adjacent parts with actual functionality.
import provides a lot of power and allows you to keep your application lean.
You can find the full example showing how it all goes together with lunr, React, and webpack. The basic idea is the same, but there's more setup in place.

In this ESP32 tutorial, we will check how to remotely control a relay using the Arduino core and the HTTP async web server libraries for the ESP32.
Introduction
In this ESP32 tutorial, we will check how to remotely control a relay. To do it, we will use the HTTP async web server library, which will allow us to set a web server on the ESP32, listening for requests that will change the state of the relay.
For an introduction on how to control a relay using the ESP32, please consult this previous tutorial.
The relay is a device that can be used to control circuits powered by the mains. In this tutorial, we will only cover the ESP32 code and the electric diagram to control the state of the relay. Please stay safe and don’t work with the mains if you don’t have experience with it, since it is dangerous.
The ESP32 board used for this tutorial was a NodeMCU. The relay board used was this one from Elecrow, which can also be obtained as part of this kit. You can check the specs of the relay here.
The electric diagram
The electric diagram needed for this tutorial is basically the same as the previous tutorial and is shown in figure 1. If you need more information about it, please consult the previous post which contains a more detailed explanation.
Figure 1 – Electric diagram for connecting the ESP32 to the relay board.
Depending on your ESP32 board, you may be able to power the relay from a 5 v digital pin that some boards have. If you are not sure if you can power the relay from your board, the best option is to use an external power supply. You can find very cheap 5 v power supplies for breadboards here.
Note that the code that we are using is agnostic to the type of actuator, as long as it can be controlled by a digital output pin. So, instead of controlling a relay, you can use it to control a LED or a motor, for example, as long you use the correct electronic schematic for the device to control.
The code
As mentioned in the introductory section, we will use the async HTTP web server libraries to set a web server on the ESP32 and to control the relay from a client over WiFi. You can check how to setup these libraries here.
So, the first part will be equal to what we have been doing in previous posts about the async web server. We include all the libraries and declare the global variables needed to connect the ESP32 to a WiFi network and to set the server.
#include <WiFi.h> #include <FS.h> #include <AsyncTCP.h> #include <ESPAsyncWebServer.h> const char* ssid = "yourNetworkName"; const char* password = "yourNetworkPass"; AsyncWebServer server(80);
We will declare an additional global variable to hold the number of the digital pin that will control the relay. This way, we have a centralized place to change the pin number, which prevents having to go through all the code when we want to use a different pin.
int relayPin = 23;
Moving on to the Arduino setup, we will first set our GPIO as an output pin, so we can use it to control the relay. To do it, we call the Arduino pinMode function, which receives as first input the number of the pin we want to configure and as second a constant indicating the mode.
We want our pin to work as output, so we pass to the function the constant OUTPUT.
pinMode(relayPin, OUTPUT);
We will explicitly set the state of the pin to low, so we always know the state of the relay when our program starts running.
This is done by calling the Arduino digitalWrite function, which receives as input the pin number and the state. For the state we pass the constant LOW, so the pin is set to GND.
digitalWrite(relayPin, LOW);
Note that if we wanted to initialize the pin with a digital high value, we would pass the HIGH constant, so the pin would be set to VCC.
Followed by that we will open a serial connection and then connect the ESP to the WiFi network, using the credentials we previously declared as global variables. After the procedure finishes, we will print the local IP assigned to the device, so the client knows the address where it can reach the server.
Serial.begin(115200); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(1000); Serial.println("Connecting to WiFi.."); } Serial.println(WiFi.localIP());
Once we finish the WiFi connection procedure, we need to declare the routes of our server.
In our case and to illustrate a slightly more complex API, we are going to have three routes for actuating on the relay: one for turning it on, one for turning it off and another to toggle it. Additionally, we will set a route to get the current state of the relay.
Note that this is one of the many options that we can follow to model our API. Another one could be having a single route taking a parameter that indicates the action to perform.
Nonetheless, one interesting pattern that we can take advantage of by using different routes is that their name can already reflect the action that will be performed, making it easier to understand for clients just by reading the URL.
Since we are going to update the state of a resource (the relay) that already exists in our server, we can follow an approach more aligned with the REST pattern and use a PATCH HTTP method [1].
Note that the HTTP method that should be used depends on what we consider a resource and if we are doing a partial or total update. Thus the use of the PATCH method may be arguable accordingly to what we consider a resource, but since we didn’t do that more conceptual analysis, the main point to highlight is that we should not use a GET method, since we are going to affect the state of the relay.
The first route we will declare will be used to turn off the relay. We will call it “/relay/off“.
In order to listen to PATCH methods, we need to pass the HTTP_PATCH enum value as second argument of the on method.
Remember from previous tutorials that we use the on method of the server object to bind a handling function to a route and that its second argument receives an enum that specifies the HTTP methods allowed on the route.
Our handling function will simply correspond to setting the state of the digital pin that controls the relay to low. This is done by calling the digitalWrite function with the same arguments we used in the setup function (the pin number and the constant LOW).
Note that before the mentioned operation, we return the answer to the client right away, so the actual execution of the command is performed after answering the client. This is a common pattern to avoid leaving the client hanging, specially when the commands may take some time to execute.
Naturally, this is an optimistically approach since we return an “OK” answer to the client before actually making sure that the command is successfully executed.
In our case there’s not much to fail and thus it is safe to follow this approach, but in more complex procedures we need to carefully analyze before going to this asynchronous command execution approach.
server.on("/relay/off", HTTP_PATCH, [](AsyncWebServerRequest *request){ request->send(200, "text/plain", "ok"); digitalWrite(relayPin, LOW); });
The next method will turn the relay on. Thus, following the previous pattern, the route will be “/relay/on”.
The method allowed on the route will again be PATCH and the handling function will set the pin to a high value.
server.on("/relay/on", HTTP_PATCH, [](AsyncWebServerRequest *request){ request->send(200, "text/plain","ok"); digitalWrite(relayPin, HIGH); });
The route for the toggle operation will be “/relay/toggle” and it will again listen to the PATCH method.
Our handling function will be similar to the previous ones, with the particularity that the new state of the pin will depend on the current one. So, to get the current state of the pin, we can call the Arduino digitalRead function, passing as input the number of the pin.
This will return the current state of the pin, which can be zero (LOW) or one (HIGH). You can confirm the values defined for these constants here.
So, we can obtain the next state by negating the current state with the “!” operator (logical not). Negating 1 will give 0 and negating 0 will give 1, which is the toggle we want.
Taking this in consideration, we can call the digitalRead function, apply the “!” operator and pass the result to the second argument of the digitalWrite function and the state of the pin will be toggled.
server.on("/relay/toggle", HTTP_PATCH, [](AsyncWebServerRequest *request){ request->send(200, "text/plain","ok"); digitalWrite(relayPin, !digitalRead(relayPin)); });
To finalize our route declaration, we will have an endpoint to return to the client the current state of the relay. It will be listening on the “/relay” route and HTTP GET methods.
To obtain the current state of the relay we use again the digitalRead function. Then, we convert the result to a string and return its value to the client.
Just as a comparison note regarding the previous commands, when the client asks for information to the server, the execution is usually synchronous so the client gets the result in the same request.
Alternative approaches may be triggering the information fetch asynchronously with a first request and then having the client polling for the result in subsequent requests.
In our case, our operation of fetching the relay state is really fast, so we opt for the simplest synchronous approach.
server.on("/relay", HTTP_GET, [](AsyncWebServerRequest *request){ request->send(200, "text/plain", String(digitalRead(relayPin))); });
To finalize, we need to call the begin method on our server object, so it starts listening to incoming requests. The final source code for this tutorial can be seen below and already includes this call.
#include <WiFi.h> #include <FS.h> #include <AsyncTCP.h> #include <ESPAsyncWebServer.h> const char* ssid = "yourNetworkName"; const char* password = "yourNetworkPass"; AsyncWebServer server(80); int relayPin = 23; void setup(){ pinMode(relayPin, OUTPUT); digitalWrite(relayPin, LOW); Serial.begin(115200); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(1000); Serial.println("Connecting to WiFi.."); } Serial.println(WiFi.localIP()); server.on("/relay/off", HTTP_PATCH, [](AsyncWebServerRequest *request){ request->send(200, "text/plain", "ok"); digitalWrite(relayPin, LOW); }); server.on("/relay/on", HTTP_PATCH, [](AsyncWebServerRequest *request){ request->send(200, "text/plain","ok"); digitalWrite(relayPin, HIGH); }); server.on("/relay/toggle", HTTP_PATCH, [](AsyncWebServerRequest *request){ request->send(200, "text/plain","ok"); digitalWrite(relayPin, !digitalRead(relayPin)); }); server.on("/relay", HTTP_GET, [](AsyncWebServerRequest *request){ request->send(200, "text/plain", String(digitalRead(relayPin))); }); server.begin(); } void loop(){}
Testing the code
To test the code, simply compile it and upload it to your ESP32, after finishing all the electronic wiring needed.
After the procedure finishes, open the Arduino IDE serial monitor and wait for the device to connect to the WiFi network.
Once the connection is established, the local IP of the ESP32 on the network will be printed. Copy that IP.
In order to send commands to the ESP32, we need to use a tool such as Postman, which allows us to perform HTTP PATCH requests, amongst many other functionalities.
So, open Postman and put the following in the URL bar, changing #yourDeviceIp# by the IP you have just copied and #command# by one of the 3 commands we have defined.
Then, on the method dropdown of Postman, select PATCH and click the send button. You should get an output similar to figure 2, where we have sent a toggle command.
Figure 2 – Sending the toggle command using Postman.
You can also get the current state of the relay by sending a GET HTTP request to the server. For this, you don’t need Postman and can simply access the URL below on a web browser.
In the video below you can check a live demo of toggling the relay.

Hi guys...
my question is about implementation of wait and notify to simulate threading...here is the Problem description:
I have an application to simulate 2 trains travelling in the same direction on a loop from station, through a tunnel and back to the station ;normaly on 2 seperate tracks.however both tracks pass through the tunnel wich has one single track: so there should be one train at a time in the tunnel...
what i need is to rewrite method useTunnel() given below so that train 1 and 2 are allowed to enter tunnel in strict rotation:train 2 should be allowed to enter first then train 1 then 2 and so on...method useTunnel should contain code to enforce the ordring of which train can enter at a given time...for this we should use wait and notify and maybe change the Tunnel constractor...how can i do this?
the code is below (classes Train.java , Tunnel.java ans Simulate.java)
many thanks for helping
//Train class

public void run() {
// each train makes 2 loops
for (int j=0; j < 2; j++) {
System.out.println("Train " + id + " leaves station");
travel(10); // train takes 10 time units to travel from station to tunnel
System.out.println("Train " + id + " arrives at tunnel");
tun.useTunnel(this); // current train uses tunnel
travel(15); // train takes 15 time units to travel from tunnel to station
System.out.println("Train " + id + " arrives at station");

However, if you're out of town or something, you may email the writeup (in text, postscript, or pdf format only, i.e. not ms word) to aistaff, but then of course you have to send this in by midnight sunday.
For the problem 5b web tester, i will ask you to include your state calculation code (same procedures as problem 1) in the file you upload for this problem. This is because the state calculation procedures you use for this problem need not be the same as the procedures you upload for problem 1.
The argument player-hand will consist of a list of two cards that the player was initially dealt; dealer-hand will consist of a list of one card, the dealer's face-up card. This procedure must return a valid reinforcement learning state (a nonnegative integer between zero, inclusive, and the number of states declared to create-tables, exclusive).
Needless to say, calc-new-state should also return a valid reinforcement learning state. I've updated the assignment handout on the handouts page.
You don't need to use a lot of states for this assignment, however, the states should represent different situations of the game.
At one extreme, you could have separate states for each possible combination of cards. However, there's a lot of "duplication" here. for example, the following initial hands: 2 and 9, 3 and 8, 4 and 7, 5 and 6, would be played the same way, so it's fine for them to be represented by the same state.
At the other extreme, you could get away with using only two states: one for "still playing the hand" and one terminal state. This, however, would treat all hands in exactly the same way, whereas you really should play hands differently depending on the value, soft hand or not, dealer's face-up card, etc.
You should use some knowledge to structure the states, but you should leave some room for the program to learn. For example, if you think you should always stand on 14 or higher and always hit on 13 or less, you might use just those two states as initial states. Your program will learn the utilities for those states so it can make an optimal decision based on what action to take in those two states. However, you have deprived your program the opportunity to learn whether it might be better to hit on 9 or less and double down on 10-13 because those two situations fall into the same initial state.
If you structure the layout of your states well, calculating the states shouldn't be much work. For my 400 state implementation, my calc-initial-state and calc-new-state are (together) about 40 lines of code (nicely broken and indented). You can take some ideas from a7example.scm.
(define e-strat (create-exploring-rl-strategy 5.0 10)) ; in the example tables i got, state 4 is one of the nonterminal ; states, so i am testing my code on that state (map (lambda (a) (get-action-transitions 4 a)) '(hit stand double-down)) ;Value: (0 0 0) (do ((i 0 (+ i 1))) ((= i 30)) (let ((a (e-strat 4 '(hit stand double-down)))) (print a " ") (increment-action-transition 4 a))) ; here's all the actions my strategy chose double-down stand double-down stand double-down double-down double-down hit stand double-down hit stand double-down double-down double-down hit stand stand hit stand double-down stand hit hit stand stand hit hit hit hit (map (lambda (a) (get-action-transitions 4 a)) '(hit stand double-down)) ;Value: (10 10 10) ; now it should pick the action with the maximum expected utility (e-strat 4 '(hit stand double-down)) ;Value: hit ; note that this is what the basic-rl-strategy does all the time (basic-rl-strategy 4 '(hit stand double-down)) ;Value: hit
A few clarifications: the value returned by a learning procedure is ignored. For this problem, it must update the utility of state fs.
My utility values did not converge as nicely as I would have liked them to. I don't think I ever saw a maximum utility value change (after a round of maybe 1000 or 10,000 hands) of less that 0.001. A maximum change of less than 0.05 or even 0.01 occurred after not too many rounds. You may want to try changing your alpha value, i.e. play some number of rounds with an alpha of 0.05 or 0.01 and then create a new learning procedure that is going to use an alpha of say 0.001 for the remainder of the rounds. You could let the maximum utility value change be your guide — if you have max changes of say 0.1 or 0.2, then decreasing alpha to 0.001 is probably not appropriate at that point.
Note that you can stop learning at any time and test how well your utility values work by playing, I would suggest, 100,000 hands with the basic-rl-strategy. (I'd keep table updates turned off here.) Remember that the policy will converge before the utility values do.
The thing is that a strategy procedure is given only the state number — not the player's cards. Therefore, you have to set up the states that that strategy needs and then encode the actions that should be taken from each state. This is essentially hardcoding a policy in the strategy procedure.
Version 1.1.3 (released 12/5) contains two minor bug fixes and some changes we needed for the web testers. the bugs fixed include: printing bug for exact numbers used as utilities or rewards, the bj-value and soft-hand? procedures now signal an error if you give them an invalid card (actually, they don't check the suit, only the value).
Version 1.1.2 (released 12/4) contains a bug fix (the dealer's face-up card was passed to calc-initial-state as it should, but the dealer's face-down card was passed to calc-new-state for transitions to nonterminal states) so this was corrected; when dealer and player both have blackjack, it's a push but wasn't treated as such (this doesn't affect learning but does affect the net winnings); there are a few new procedures in the support code (documented below) though you probably don't need these; and finally, the error checking on arguments passed to the support code was slightly improved.
Version 1.1.1 (released 11/29) contains no changes to the functionality of the support code. There was one minor bug fix and a little cleaning up of the namespace.
Version 1.1 (released 11/26) was the initial release of the support code.
(print-rl)This procedure calls print-transitions, print-rewards, and print-utilities.
This web tester only checks to make sure that you have uploaded a working (and consistent) set of state calculation procedures. I'd advise you to wait until you have done at least an initial implementation of your game-state to reinforcement-learning-state idea and have tested it by learning a blackjack player.
The a7example.scm file will pass this test; however, you will (after the fact) receive 0 credit (and still use one of your submissions) if you just submit this file (or trivial variations of it). You should upload something much closer to your final state calculation scheme.
This web tester will have your basic-rl-strategy procedure choose actions in a randomly generated (but still blackjack-like) state space.
This web tester will make sure that a strategy procedure returned by your code actually does explore the different actions from a state but later picks the action with the maximum expected utility.
This web tester will check that your code does updates using the temporal differencing update rule correctly.
This web tester will simply collect a file; there will be no tests run online
The file you turn in must have the tables you saved after learning a model of blackjack (e.g., by playing the random player for at least 10,000 (though preferrably 100,000 or more) hands).
You must also include your state calculation procedures (i.e., the same procedures as for problem 1) that you used to create these tables..
This web tester will simply collect a file; there will be no tests run online
The file you submit must have your final tables, and you should include any code you wrote for this part, e.g., any code to "automate" the temporal differencing learning..

Mapper component
The Mapper component handles the mapping of CQL table columns to fields in your classes.
The Mapper component (previously known as cqlpoco) is a lightweight object mapper for Apache Cassandra. It lets you write queries with CQL, while it takes care of mapping rows returned from Cassandra to your classes. It was inspired by PetaPoco, NPoco, Dapper.NET and the cqlengine project.
To use the Mapper:
1.- Add the following using statement to your class:
using Cassandra.Mapping;
2.- Retrieve an
ISession instance in the usual way and reuse that session within all the classes in your client
application.
3.- Instantiate a
Mapper object using its constructor:
IMapper mapper = new Mapper(session);
New
Mapper instances can be created each time they are needed, as short-lived instances, as long as you are
reusing the same
ISession instance and mapping configuration.
The Mapper works by mapping the column names in your CQL statement to the property names on your classes.
For example:
public class User { public Guid UserId { get; set; } public string Name { get; set; } } // Get a list of users from Cassandra IEnumerable<User> users = mapper.Fetch<User>("SELECT userid, name FROM users"); IEnumerable<User> users = mapper.Fetch<User>("SELECT * FROM users WHERE name = ?", someName);
Simple scenarios such as this are possible without doing any further mapping configuration. When using parameters,
use query markers (
?) instead of hardcoded stringified values, this improves serialization performance and lower
memory consumption.
The Mapper will create new instances of your classes using the parameter-less constructor.
Configuring mappings
In many scenarios, you need more control over how your class maps to a CQL table. You have two ways of configuring Mapper component of the driver will use the configuration defined
when creating the
Mapper instance to determine to which keyspace and table it maps to, using
MappingConfiguration.Global when not specified.
Mapper API example
A simple query example is great, but the Mapper has many other methods for doing things like Inserts, Updates, Deletes, selecting a single record and more. And all methods have async counterparts. Here’s a quick sampling.
// All query methods (Fetch, Single, First, etc.) will auto generate // the SELECT and FROM clauses if not specified. IEnumerable<User> users = mapper.Fetch<User>(); IEnumerable<User> users = mapper.Fetch<User>("FROM users WHERE name = ?", someName); IEnumerable<User> users = mapper.Fetch<User>("WHERE name = ?", someName); // Single and SingleOrDefault for getting a single record var user = mapper.Single<User>("WHERE userid = ?", userId); var user = mapper.SingleOrDefault<User>("WHERE userid = ?", userId); // First and FirstOrDefault for getting first record var user = mapper.First<User>("SELECT * FROM users"); var user = mapper.FirstOrDefault<User>("SELECT * FROM users"); // All query methods also support "flattening" to just the column's value type when // selecting a single column Guid userId = mapper.First<Guid>("SELECT userid FROM users"); IEnumerable<string> names = mapper.Fetch<string>("SELECT name FROM users"); // Insert a POCO var newUser = new User { UserId = Guid.NewGuid(), Name = "SomeNewUser" }; mapper.Insert(newUser); // Update with POCO someUser.Name = "A new name!"; mapper.Update(someUser); // Update with CQL (will prepend table name to CQL) mapper.Update<User>("SET name = ? WHERE id = ?", someNewName, userId); // Delete with POCO mapper.Delete(someUser); // Delete with CQL (will prepend table name to CQL) mapper.Delete<User>("WHERE id = ?", userId); | https://docs.datastax.com/en/developer/csharp-driver/3.7/features/components/mapper/ | CC-MAIN-2019-43 | refinedweb | 540 | 51.44 |
CPSC 124 (Winter 1998): Lab 3
Subroutines (Part 1)
THE THIRD LAB IN COMPUTER SCIENCE 124 deals with using subroutines that have been written for you and with writing the insides of subroutines whose basic format is already written for you. In the process, you will create an applet and learn something about how applets respond to event and how they can use multi-threading. You will also get more experience with using while statements and if statements. Next week, we'll move on to designing and writing complete programs that include subroutines that you write from scratch.
You'll need several project folders from the cpsc124 folder on the network. Copy the following folders into the java folder on your M drive: "Jumping Square Starter", "Mosaic Starter #1", and "Mosaic Starter #2". Each of these is the starting point for one of the exercises at the end of the lab.
Sample solutions for each of the exercises can be found on the following separate pages: Exercise 1. Exercise 2. Exercise 3.
The exercises at the end of the lab are due in class on the Monday following the lab.
Outline of the Lab:
- About the MosaicFrame Class
- A Better Random Walk
- Conversion Experience
- An Applet with Action
- Exercises
About the MosaicFrame Class
A subroutine is a set of instructions for performing some task, chunked together into a "black box" and given a name. A programming language can have some built-in subroutines, like Math.random(), that are a part of the basic language and are always available. A programmer can also write new subroutines and then use them in the same way that built-in subroutines can be used. Of course, one programmer can also use subroutines written by another programmer. For example, you have already used subroutines defined in the Console class, which is not a standard part of Java but was provided to you to perform certain kinds of input/output tasks.
In the first two exercises of the lab, you will again be using subroutines that have already been written as methods in a class that is provided to you. The class is called MosaicFrame. An object in this class represents a window containing a grid of colored rectangles. Initially, all the rectangles are black, but methods are provided for setting the color of a given rectangle and for checking on the current color of a given rectangle.
You should open the folder "Mosaic Starter #1." (If you have not already copied it into the java folder of your M drive, do that now.) Execute the program. You'll see a small red rectangle that wanders around in a black window. (Actually, the "motion" is an illusion that is achieved by turning various little squares in the window from red to black and back again.) You will want to read the source file, MosaicApplication.java, since you will have to modify this file to do Exercise 1. You might also want to look at the comments in MosaicFrame.java, since that is the file that defines all the methods that have been provided for working with MosaicFrame windows. You'll only need a few of the methods, though, and those are mentioned below.
A MosaicFrame window can be created and opened with a statement such as:
MosaicFrame mosaic = new MosaicFrame(20,30);
The window created will have 20 rows and 30 columns of rectangle. Each rectangle will be 10 pixels by 10 pixels (so it is, in fact, a square). The name of the window is "mosaic", and this variable can be used to call methods for checking as setting colors. You can, of course, use a different name for the window, and you can use different numbers of rows and columns. It is also possible to specify the width and the height to be used for the rectangles. See the Java source code files for details.
If there are R rows in the window, then they are numbered from 0 to R-1. Similarly, if there are C columns, they are numbered from 0 to C-1. You can specify a particular rectangle by giving the number of the row that it is in and the number of the column that it is in. If you use row or column numbers outside the valid ranges, it won't crash the program. However, it's still an error and you might not get the effect that you want. I will be looking for this type of error when I grade your lab reports. You should try to avoid them by careful and thoughtful programming.
To use a MosaicFrame, you have to know a little about the way colors are specified on a computer. Any color that can be displayed on a computer is made up of some combination of the "primary colors," red, green, and blue. In MosaicFrame, the level of each primary color is given as an int number in the range 0 to 255. A color is specified by three numbers giving the levels of red, green, and blue in the color. Colors specified in this way are referred to as "RGB colors." A color with a red component equal to 0 contains no red at all; a color with a red component equal to 255 contains the maximum possible amount of red. Black is given by red, blue, and green components all equal to 0. White is given by all components equal to 255. (In MosaicFrame, if you try to use numbers outside the range 0 to 255 to specify a color, any number less than 0 will be treated the same as 0, and any number bigger than 255 will be treated the same as 255.)
Here are some methods that you can use with a variable, mosaic, of type MosaicFrame:
- mosaic.setColor(row, column, r, g, b) sets the color of the specified rectangle, where r, g, and b are the red, green, and blue components of the color (in the range 0 to 255).
- mosaic.fill(r, g, b) fills the window with a uniform color by setting the color of each rectangle to the color specified by red, blue, and green components r, g, b.
- mosaic.fillRandomly() fills the window with randomly colored rectangles.
- mosaic.delay(n), where n is an integers, will cause the program to wait, without doing anything, for about n milliseconds. 1000 milliseconds are equal to one second. The timing is not very exact. This can be used to control the speed at which a program executes.
The following methods are used to find out the current levels of red, green, and blue in a given rectangle. The value returned by the routine would ordinarily be assigned to a variable of type int, as in: "b = mosaic.getBlue(r,c);"
- mosaic.getRed(row, column) returns an integer in the range from 0 to 255 giving the red component of the current color of the rectangle in the specified row and column.
- mosaic.getGreen(row, column) returns an integer in the range from 0 to 255 giving the green component of the current color of the rectangle in the specified row and column.
- mosaic.getBlue(row, column) returns an integer in the range from 0 to 255 giving the blue component of the current color of the rectangle in the specified row and column.
Finally, here is a useful method that indicates whether or not the mosaic window has been closed by the user. The method returns a boolean value. In the sample program in "Mosaic Starter #1", this method is used in a while loop that continues as long as the window is open.
- mosaic.stillOpen() returns a boolean value indicating whether or not the MosaicFrame window has been closed by the user. This value is true if the window is still open and is false if the user has closed the window.
(Note, by the way, that the mosaic window is similar to the one that I describe in Section 3.6 of the text. However, in the text, color components are specified as real numbers between 0.0 and 1.0 instead of an integers between 0 and 255. I decided to switch to integers because integers are what are actually used in the computer to represent colors. Here is the source code for MosaicFrame and for another class, MosaicCanvas which it uses. You should not expect to understant the source code at this point in the course.)
A Better Random Walk
For your first exercise, you will modify the program in "Mosaic Starter #1" so that it does a more interesting kind of random walk. The effect that you will try to achieve is shown in a sample applet on a separate page. You should look at the example and read the comment on that page.
The changes that you have to make to MosaicApplication.java are actually fairly small, but you won't be able to do them easily unless you really understand how the original random walk program works. Read the source code, read the comments, and make sure you understand what is going on. (You can also read the source code here.)
You want to modify the program so that a "disturbance" wanders around the window. This is not much different from the wandering red square, except that the disturbance itself is invisible. Each time the disturbance visits a square, you want to read the level of green in that square, add 10 to that level (up to a limit of 255), and reset the color of the square.
You'll want to make the "delay" in the while loop pretty small to get a good effect. I use "mosaic.delay(5)" in my applet.
You might want to try this program using red, blue, or gray instead of green. (A gray color is one that has equal red, blue, and green components.)
Conversion Experience
For your second exercise, you should use the starter folder "Mosaic Starter #2." Copy it into the java folder on your M drive, if you have not already done so. Open the project in this folder, and execute the program. You get a window filled with randomly colored squares. This is produced by a single call to the method mosaic.fillRandomly(). (You can read the source code here.)
Your assignment is to add a while loop to the main() routine so that the program will behave like the sample solution to this exercise, which is shown as an applet on a separate page.
In your loop, you should first choose a random square by choosing a random row and a random column. Randomly select one of the four neighbors of that square, and convert the color of the selected square to the color of its selected neighbor.
(This program models, in a vague way, a population where people have a tendency to be like their neighbors or to join coalitions with their neighbors. Let's say each color represents a political party. Initially, everyone belongs to a different party. However, people look around at what their neighbors are thinking, and they have some tendency to be converted by their neighbor's opinion. What will happen in the long run? Remember that "extinction is forever." Once the last square of a give color is converted, that color is gone forever.)
The while loop you want to write has some similarities to the loop in "Mosaic Starter #1." In fact, you might want to copy-and-paste that loop into the program in "Mosaic Starter #2." However, the problem here is significantly different and you should not expect everything to carry over exactly. Think about what you want to do, and plan your while loop before you start working on it.
An Applet with Action
For the third exercise of the lab, you will be working on an applet. The starting point is the folder "Jumping Square Starter." Copy it to your M drive if you have not already done so. Open the project in the "Jumping Square Starter" folder and execute it. (You can also read the source code here.) The applet displays a red square in a random position. Each time the user clicks on the red square, it jumps to a new location. You'll also see that the number of seconds that have elapsed since the applet started is displayed in the upper left corner of the applet. (Note that the applet might flicker a bit when the time changes or when the square jumps. There is a way to fix this, but I am trying to keep things simple for now. We will return to this problem later in the course.)
Your assignment is to turn this modest little applet into a duplicate of the rather annoying applet that is shown on a separate page. The new version is a kind of game. The square jumps around randomly. The user tries to click on it. The applet keeps track of how may time the user hits the square and how many times the user misses. These numbers are displayed on the applet along with the elapsed time.
There are two different things going on in this applet: It responds to the event that occurs when the user clicks on the applet. And it has another process or thread that runs continuously, like a separate program. It is this thread that keeps track of the time. In the final version of the applet, the same thread also moves the square around even when the user doesn't click on it.
Here's how it works. First of all, the class MosaicApplet has a so-called "mouseDown" method, which takes the form:public boolean mouseDown(Event evt, int x, int y) { . . // commands to be executed when user clicks in the applet . return true; }
This method is an event handler. It is a routine that is called by the system when the user clicks on the mouse. It is not ordinarily called from elsewhere in the program. Your job as a programmer is to write the inside of the mouseDown() routine to specify what should happen when the user clicks on the applet. The x and y parameters, which are provided by the system when the routine is called, tell you the horizontal and vertical coordinates of the point in the applet where the user clicked.
The other aspect of this applet is the separate thread that runs independently of user-generated events. The MosaicApplet class begins with the line
public class MosaicApplet extends Applet implements Runnable
To say that a class "implements Runnable" means, essential that it has a "public void run()" method that can be run as the program of an independent thread. In this example, the thread is created in the applet's start() method, which is called by the system when the applet starts to run. As soon as the thread starts, it begins to execute the run() method of the applet. The run() method is provided for the use of this thread, and it is not meant to be called directly. By filling in the run() method, you are in effect writing a program for the thread. Any class that contains a run() method can be used to create threads in the same way, and it is possible for a program to create many threads that are executed concurrently (in addition to the basic, original thread that I have been referring to as the "system.")
Your job is to make several modifications to the MosaicApplet class:
- Add variables to count the number of times that the user hits the square and the number of times that the user misses. Since these variables are to be used in several methods, they must be declared outside of any method, just like the existing variable, elapsedTime.
- Modify the paint() method so that in addition to displaying the square and the elapsed time, it also displays the number of hits and the number of misses.
- Modify the mouseDown() method so that in addition to checking whether the user has clicked inside the square, it also keeps track of the number of hits and the number of misses.
- Modify the run() method so that in addition to keeping track of the elapsed time, it also makes the square jump at random occasionally. Note that a method, doJump(), is provided to make the square jump. Check out how it is done in mouseDown(). In my applet, in the run() method, I make the square jump with a probability of 0.1 each time the while loop is executed.
After your applet is created, you will want to publish it on the Web so that you can annoy your friends in California. To do this, you will have to use FTP to copy the files JumpingSquare.class and JumpingSquare.html to your account on hws3.hws.edu. If you don't remember how to do this, review Lab 1. You might want to edit JumpingSquare.html to add some text or make the page look a bit fancier. If you want some hints on maintaining your Web site, look back at Lab 2.
Exercises to Turn in
Exercise 1. Turn in a print out of the "random walk" program that you modified above. The work you did was all in the file MosaicApplication.java, and that is the only file you should turn in. Make sure that it follows good programming style. You will have to erase some of the comments that are there and replace them with your own.
Exercise 2. Turn in a print out of the MosaicApplication.java file for the "conversion" program that you wrote above. Again, make sure it follows proper style.
Exercise 3. For this exercise, turn in a copy of the JumpingSquare.java program that you modified above. For this one time, you don't have to worry about getting the comments right. I also want to check that you have successfully added the applet to your web site on hws3.hws.edu. Please give me the URL for your page.
Optional Extra-credit Exercise. If you like, you can get a few points of extra credit by making one of your "mosaic" programs from Exercise 1 or Exercise 2 into an applet and adding it to your Web site. Use the folder "Mosaic Applet Starter" as a starting point. Like the JumpingSquare applet, the MosaicApplet has a run() method. You should be able to copy your program (except for the line that creates the MosaicFrame) into the run method of the MosaicApplet. You might want to make up your own mosaic program. Be creative! You could even make the applet respond to mouse clicks by providing a "public void boolean mouseDown(Event evt, int x, int y)" method. | http://math.hws.edu/eck/cs124/labs98/lab3/index.html | crawl-001 | refinedweb | 3,140 | 71.65 |
I have video features (Batch, Time, Spatial, Feature_dim), like (32,15,4,2048).
and I need first a dimension transform using a
nn.Liear(2048,512) .
But some features are masked according the associating mask (B,T,S) (True means yes,False means no)
How do I avoid updating this layer with unwanted features ?
I have video features (Batch, Time, Spatial, Feature_dim), like (32,15,4,2048).
How is the mask applied? How do you update the parameters of this layer? Is there a loss function?
For example :
in attention models the mask is multiplied by the attention scores to avoid taking them into account in the calculation of the output: everything is managed at the model level
in classification it is also common to provide a weight parameter to the loss function (binary_cross_entropy_with_logits, cross_entropy…) to avoid the update of some neuron in output : everything is managed at the loss level.
Or if we have to deal with a regression, we can play on the loss like this:
import torch import torch.nn.functional as F B, n = 4, 6 torch.manual_seed(0) y = torch.empty((B, n)).uniform_(-10, 10) torch.manual_seed(1) y_pred = torch.empty((B, n)).uniform_(-10, 10) if True : # if the mask is batch wise mask = torch.empty(B).random_(2).bool() loss = F.mse_loss(y_pred, y, reduction='none').sum(dim=1) * mask else : # if the mask is element wise mask = torch.empty((B, n)).random_(2).bool() loss = ( F.mse_loss(y_pred, y, reduction='none') * mask ).sum(dim=1) loss = loss.mean() # loss.sum() loss

This procedure tests your configuration and validates its readiness to be deployed to Windows Azure environment.
To test readiness for Windows Azure deployment
In this step you will deploy the application to the cloud using the Windows Azure management portal. First you’ll need to create a service and a service configuration file, called service package, and then upload it to Windows Azure environment using Windows
Azure management portal.
For Configuration file, click the corresponding Browse Locally… button, navigate to the folder where your ServiceConfiguration.cscfg is, and select the file.
Click on Add Certificate button to add your certificate to be deployed, but first you need to export the certificate into file. To export the certificate into file follow these steps:
Open mmc console by first clicking on Windows button in task bar and typing mmc. You should see
mmc.exe appears in search results. Click on it.
When mmc console appears click on File option and then on
Add/Remove Snap-in… option.
In the Add or Remove Snap-ins dialog box choose Certificates from the available snap-ins list and click on
Add> button.
Choose Computer Account option and click Finish
button.
In the Select Computer wizard page select Local Computer (the computer this console is running on) and click
Finish button. The click OK button.
Expand Console Root folder.
Expand Certificates(Local Computer) folder.
Expand Personal folder.
Click on Certificates folder to list available certificates.
Locate your certificate in the list.
Right click on the certificate and choose All Tasks and then
Export… option.
Click Next on the welcome page of the wizard.
On the Export Private Key page choose Yes, export the private key option and click
Next button.
On the Export File Format leave the default option which is Personal Information Exchange - PKCS #12 (.PFX) and click
Next button.
On the Password page of the wizard specify password. You will need it when uploading the certificate to Windows Azure environment via management portal.
On the File to Export page of the wizard specify destination file and click
Next button. Make a note where you are saving the file. Note, since the certificate being exported has private key extra care should be taken to not exposing it to the public. It’s best if you delete the file altogether after uploading it to
Windows Azure environment.
Click Finish to complete the wizard. You should be presented with
The export was successful message, click OK button to dismiss the message.
Switch back to Windows Azure management portal where you opened a dialog box to locate your certificate (.PFX) file and locate the certificate file you have just exported.
Specify the password for your certificate in the Certificate Password field.
Click OK. You will receive a warning after you click OK because there is only one instance of the web role defined for your application (this setting is contained in the ServiceConfiguration.cscfg file). For purposes of this walk-through,
override the warning by clicking Yes, but realize that you likely will want more than one instance of a web role for a robust application.
You can monitor the status of the deployment in the Windows Azure management portal by navigating to the
Hosted Services section. Because this was a deployment to a staging environment, the DNS will be of the form http://<guid>.cloudapp.net. You can see the DNS name if you click the deployment name in the Windows Azure management portal
(you may need to expand the Hosted Service node to see the deployment name); the DNS name is in the right hand pane of the portal. Once your deployment has a status of Ready (as indicated by the Windows Azure management portal), you can enter the DNS name
in your browser (or click it from the Windows Azure management portal) to see that your application is deployed to the cloud.
Although this walk-through was for a deployment to the staging environment, a deployment to production follows the same steps, except you pick the production environment instead of staging. A deployment to production results in a DNS name based on the URL
of your choice, instead of a GUID as used for staging.
If this is your first exposure to the Windows Azure management portal, take some time to familiarize yourself with its functionality. For example, similar to the way you deployed your application, the portal provides functionality for stopping, starting,
deleting, or upgrading a deployment.
Important
Assuming no issues were encountered, at this point you have deployed your Windows Azure application to the cloud. However, before proceeding, realize that a deployed application, even if it is not running, will continue to accrue billable time for your subscription.
Therefore, it is extremely important that you delete unwanted deployments from your Windows Azure subscription. To delete the deployment, use the Windows Azure management portal to first stop your deployment, and then delete your deployment. These steps take
place within the Hosted Services section of the Windows Azure management portal: Navigate to your deployment, select it, and then click the
Stop icon. After it is stopped, delete it by clicking the
Delete icon. If you do not delete the deployment, billable charges will continue to accrue for your deployment, even if it is stopped.
Publish to production clicking on you deployment node so that Swap VIP
ribbon appears.
Click on Swap VIP ribbon and then OK button. The deployment to production should take couple of minutes.
In the next procedure you will update the the package and the ACSv2 to reflect on the address changes from staging environment to production.
Next procedure helps you to verify your application is functional when running in Windows Azure environment.
Cant read the code... no bar on bottom to move right. :(
VS 2012 doesn't have 'Add STS Reference'. WIF SDK doesn't create it in 2012. However, use the Identity and Access Tool. Open Tools ->Extensions and Updates. Click “Online”, search for “Identity” in the Search box.
Click “Identity and Access Tool”, and install it. Restart Visual Studio. When you right click on the WebRole, you should see a new menu item, “Identity and Access...".

Put character back.
The function checks if c matches the character right before the current position of the input sequence, if so, the get pointer is moved back one character, making the character once again available to input functions.
Parameters.
Return Value.
The value of the character put back.
If parameter c doesn't match the expected character or if the get pointer is at the beginning of the input sequence, the value returned is EOF.
Example.
// sputbackc
#include <iostream>
using namespace std;
int main () {
char ch;
long n;
streambuf * pbuf;
pbuf = cin.rdbuf();
cout << "Please enter some letters and after a number: ";
do {
ch=pbuf->sbumpc();
if ( (ch>='0') && (ch <='9') )
{
pbuf->sputbackc (ch);
cin >> n;
cout << "You entered number " << n << endl;
break;
}
} while (ch != EOF);
return 0;
}
This example gets characters form standard input one by one. When the first
numeric digit is found, sputback is called to restore the position in the
stream to that digit in order to be extracted as part of a number using standard
operator >>.

by Amber Farmer I picked this photo for the cover because I was drawn to it's vibrant colors and Georgia O'Keeffe essence. Additionally, I found humor in the juxtaposition of crisp green lettuce in the middle of our Kansas winter and the array of puns lettuce afforded me. So lettuce turnip the beet. Cheers.

e've all had those days; you get home and all you want to do is to relax. You don't feel like cooking and the thought of getting back out and driving to XYZ restaurant makes your head hurt. You retreat, "delivery it is." You get into your kitchen junk drawer and start perusing to-go menus..."hmmm, let's see...shall we have...Chinese or Pizza?" Your head now hurts a little bit more and your craving for XYZ restaurant is a little bit stronger. You're in a (insert any day that ends in "y") pickle. That is, until now.
Topeka2Go is a restaurant food delivery marketing service. You can go to Topeka2Go website or app and have food delivered from almost 40 local restaurants including Pepe and Chelas, The Wheel Barrel, Pizagels and a few national chains. Prior to Topeka2Go, Donovan was running his own Dine Time Taxi service and that is when he met his partners Anthony Swaintek and Mike Hall. It was the "perfect storm." Anthony and Mike manage the software and marketing while Donovan is on the ground with the day-to-day operations, working closely with their drivers and partners. The business started with a franchise in Topeka just over a year ago and now have 25 nationwide (time of printing) and are opening several new franchises each month. "In 24 months we will have 300 franchises open and there is a chance we will be global," said Donovan. "We will be one of the largest delivery services in the United States." Not to shabby for a boy from Carbondale who graduated from Santa Fe Trail. Donovan is proud of his routes, and that his growing business comes straight out of Topeka. “I am proud of Topeka. This is my baby. I have bragging rights.� aseveneightfive
BONUS: You can
order from multiple restaurants for one delivery.

LIVES fo x / w ills c olla b oration Tom Krebs | photos provided
CD Review
W
ould it be wrong for me to describe the twelve tunes on the new Greg Fox/Ryan Wills collaboration, "Parallel Lives," as especially tasty and exceptionally crafted? No, I don't think so… because they are." Fox writes in the liner notes, “Ryan and I have had a lot of parallels in our life.” What is clear to me, after giving the CD a number of attentive listenings that is this effort is about their musical lives, rather than running parallel, becoming blended into one. At the heart of their effort are three key ingredients of a good set of tunes: insightful and compelling lyrics; wonderfully woven, tight harmonies; and backing guitar work, with some occasional strings and keyboards, that complements, not overwhelms, the melodies and harmonies. The opening track, "What Defines A Man," sets the standard for the introspective and catchy lyrics that permeate the entire CD: Is it his beard and mustache, is it muscle is it mass, or is it heart, or is it cash? His rights or his wrongs, his fists or his songs, his first words or his last? Just what defines a man? ….is what defines a man. Other songs I found particularly compelling were "Run," "Dragonfly" and "It’s Not the End." "Run" certainly has a Simon/Garfunkel quality to it with both a call and response component on the verse as well as tight harmonies on the chorus.
"Dragonfly" offers a fun little play on words between the title and the lyrics. The harmonies on the chorus are again very tight, with Wills taking the high part and Fox providing the melody. "It’s Not the End" showcases the two men’s voices, dancing and weaving around each other through the verses, coming together during the uplifting chorus. Also in the liner notes are shout out from both Fox and Wills for Ryan’s dad, Randy, who produced the album. Perhaps the last song, "Thirsty for the Water," is the best example of a song being amped up with some additional voices and other studio effects that really make the song vibrate. "Parallel Lives" is a collaboration in the truest sense. The songwriting credits are shared equally; all songs but one are performed by both; and themes important to both run throughout. In my perfect world, I would be lucky enough to have the two sitting around my fire pit with a few other friends on a crisp fall evening and playing these tunes.

comfort food
for the soul ARTtitude by Michelle Leivan | Kansas Art Gallery | ArtsPrintExpress.com
Featured Artist: Kathleen Cobb
W.
[LEFT EDGE] Edge of a Kansas Meadow [LEFT} Garlic [BELOW] Kathleen Cobb, artist [RIGHT] Light on the Past
One such artist is Kathleen Cobb, who creates cozy comfortable wistful paintings that conjures memories and prompts images in our dreams. Seeking out the stillness of nature and the perfect scene to express her love of the land, Kathleen regularly finds inspiration throughout the Flint Hills and for when she returns to her studio to complete the quiet images. These adventures result in misty visions created with her distinctive color pallet with soft brush strokes that echo lazy days in nature.
‘‘
I hope to draw the viewer into feeling as though they're there, and wanting to go around the bend to explore more.
Kathleen inspires. A collection of Kathleen Cobb’s work “For the Love of the Land” is presented through the rest of the year at the new Kansas Art Gallery located with Art Print Express at 1047 SW Gage, Suite B. Studio hours are 10a-6p Tuesday through Friday and Saturday 10a-1p. aseveneightfive

I've got a New Years resolution for you....go to church.
M
any consider Kris Lager Band (KLB) to be one of the most exciting bands on the scene today and deservedly so. Their electrifying and uplifting performances have garnered them a strong grassroots following. They embody a "Celebrate Life" mantra that resonates throughout their live performances. Their music is infectious and uplifting, demanding the attention of your soul and feet. "The Feel Good Band of the Century."
A KLB show is a legitimate Rock ‘n’ Roll Revival and an Electric Church. The energy this band throws out from the drop of the first note creates a feel good dancing, singing and hollering.”
14." Kris Lager Band isn't a peg you can fit into some square genre box, albeit whose musical tastes do? This is why they are the perfect headliner for Topeka's New Years Eve Party at the Ramada Inn, where they will complement the other seven bands playing around the hotel and take you into 2017 with high spirits and tired dancing feet. As one might holler when music commands your undivided attention and fills your entire soul with positive vibrations; KLB is "taking you to church" this new year. aseveneightfive

Loved playing this place! George was an amazing sound guy and made us feel very comfortable on a stage that we have never gigged on before! We will return, great venue! Wow!! So pleasantly surprised at how awesome this place was last night. Excited for the future nights here. One thing is for sure, there is definitely one place that will keep raising the bar for live entertainment in Topeka and that place is Quintons, Topeka.
Q
uinton's Bar & Deli is a staple in Lawrence, known for great sandwiches and attractive, friendly staff. So when owner Steve Gaudreau opened a Quinton's in Topeka seven years ago, foodies and college students were elated. Over the years the Topeka Quinton's, as many businesses, have seen ups and downs but always strived to provide a high quality product to their consumer. However, some might argue that consumers become less than desirable as the night progressed and safety was at times a concern. Add that it was located in a Lindenmuth property which was as questionable as the "Bermuda Triangle" - [the nickname for the bar trio located at Huntoon and Gage.] The peak of speculation for some was a shooting that occurred in the adjacent parking lot last summer. For some, Quinton's could not provide the comfort food needed to move forward. Until now. Konner Slattery, assistant general manager and Kansas University graduate ('15) with a degree in marketing has a vision to elevate Quinton's food, staff and entertainment offerings while rebuilding their reputation. Konner wants
Quinton's to be an active community partner, a neighborhood champion, and supporter of the arts. Konner made a strategically smart move last August and hired George Vayler IV, owner of Rundown Studios, to collaborate with him. The result is Q's Live - a new venue where people can enjoy good company, great food, a few adult beverages and experience outstanding live music performances from local and regional acts. New sound, stage and lighting were installed and the team quickly created a schedule that included live music on Fridays and Saturday, plus acoustic sets during the week [Tuesday Bluesday 8-11p / Acoustic Thursday]. Q's Live is a testament to putting your money where your mouth is. The whole outfit is top of the line, from the late-night menu, to the service, to the way the room is divided up without a break in the acoustics. Q's Live has put itself on the dial as the go-to place for live music and in just a short few months. If you haven't visited for a while, check it out. Tuesday is acoustic night with 1/2 price burgers; or visit on a weekend night for some great bands. aseveneightfive

heers New Belgium, who is celebrating 25 years of craft brewing. They've also found themselves, for the eighth year in a row, named a top company to work for by "Outside" magazine. The reasons, stated by their 800 stake-holding employees including some stellar perks.

Oh, and everyone gets a free beer every day and a 12-pack each week.� Along with these success, New Belgium will ring in the new year with the most ambitious portfolio re-imagining in their history, according to spokesperson Bryan Simpson in a press release. "We've got a lot of excitement, momentum and energy coming out of the pilot system and that makes for a bounty of great beers with interesting twists."

o question social media has altered the dining experience, creating a new consumer: the snap happy, social media savvy, food blogger.
Instagram has made the importance of plate presentation almost equivalent to taste. Food blogging has built communities of food enthusiasts and Facebook groups have connected people to reviews. Now all your restaurant news is on the fly - but it's being reported, for the most part, by the consumer. The consumer is now the authority to raise a restaurant's reputation or expose their faults with just a few keystrokes, and why shouldn't they be - they are the ones footing the bill... We have social proof at our fingertips, and we have the power to make or break local eateries and shape our local cultural food landscape. Personally, I've begun to limit my chair standing photo sessions with my plates (I used to go to lengths to position my plate in the perfect lighting for that photo, much to my dining guest's despair), not out of laziness but because there is a plethora of great sites and people doing the work for me. Therefore, here is a list of some of some of my favorites. aseveneightfive 26

Monsoon Express from TastingTopeka.com
Andrea Smith is a transplant to Topeka and after being active on a few foodie FB pages, decided there was a need for a dedicated website directory of local restaurants. The is the most aesthetically pleasing database to date, in my opinion. She recently partnered with Arminda Guerrero, founder of Topeka Dining Group, whose focus is on local area restaurants and bringing people together. The group meets once a month at different local restaurants (JAN MLK Day at Thelma's Corner). Everyone is invited to join, combining good ol' fashion networking with food.

A large window brightens up the main bar area and allows paswerbyers inside Fairlawn Plaza a clear view of the scene prior to entering, and the wall between the main bar and the music area has been opened - achieving a more balanced and connected venue.
Henry t's menu has been updated with notable changes including their use of fresh avocados (no packaged guac.), Yankee Tank brews (well, not so new but worth mentioning) and the addition of desserts to their gluten free menu, thanks to a partnership with Shana Cakes, located in downtown Topeka. LAROCCA'S PIZZA has
opened a second location at 5145 SW Topeka Blvd. They are open Tuesday Sunday from 11a to 9p with delivery. The flagship store, located on Gage is closed Monday - Wednesday, open 11a-9p Thursday - Saturday and 11a-7p Sunday. Look at the #785weekender for music on select Saturday evenings.

f you mention Fuzzy's (Fuzzy's Taco Shop), you'll get an almost orgasmic reaction from those in the know "Ohhhhhh, Fuzzy's" they sing, drawing out the "z" with a purr. Not a bad reaction for a little taco shop with a naughty name and "Eat Me" tshirts. Albeit a locally owned franchise (something we don't highlight very often), Fuzzy's is coming to Topeka and it's too good to not share. John Records along with his wife and daughter opened the Lawrence store five years ago and in March 2017 plan to fuzz up Topeka at 2614 SW 17th, in the old Teams Sporting Goods store. The family-friendly Mexican restaurant will offer their fantastic menu with different dishes to stimulate your sense including Baja fish tacos, smothered burritos and salads that are out of the world. The quality, quantity and servings are plentiful and priced moderately. They will be stocked with a full bar and also serve breakfast. If you have driven the 20 minutes to experience this gem in Lawrence at the corner of 11th and Mass, then you know the euphoric rush. If you have not, what are you waiting for? Oh, you can wait 'til Fuzzy's opens in Topeka, but that might make for a long, lonely winter. Welcome to your new addiction. aseveneightfive

rover's Smokehouse was a Topeka culinary tradition for over 40 years, prior to closing in June 2015, probably best known and loved for their sauce. If you've been craving this sweet, flavorful meat enhancement, look no further than The Landing by Shawnee Lake. Owner Tommy Lewis received the secret recipe, hand-written on an old piece of paper, missing some key measurements. After several attempts, the sauce is now being reproduced in house and tastes just like the original. It is served on all of The Landing's barbecue dishes.

EAT LOCAL REVIEW F A N D O N ' T B L A S T S H A R E 32
give them some love!

by Martie Rison | graphics LinkedIn.com
e all have that favorite place, that one restaurant that feels like a real treat to visit. If you are lucky, your place is a mom + pop that is as unique in atmosphere as it is in flavor. Writing this now I can think of some places in Topeka that fit the bill: Bobo's, the Wheel Barrel and Juli's, just to name a few. There are some restaurants that were so fantastic, like Pore Richards and China Inn, they still stir real love and loyalty from their customers many years after their doors closed. When a place that has been so beloved for so many years closes, there is often an outcry in the community. We hate to see them go. Have you ever wondered what you can do today to help keep your favorite local restaurants in business for many years to come? There are a few things you can do that take very little time and effort that make a huge impact on the restaurants you love. To put it quite simply, be their biggest fan.
Your words are powerful.
One of the greatest gifts you can give to your favorite restaurant is to tell your friends and family about why you love the place. Don't just keep your adoration for their dishes to yourself, shout it from the rooftops! Your words will plant a seed in the minds of many people and that seed will either spark curiosity or fond memories. You could even help the community get excited about a new restaurant that is just getting started. Owning a small business is hard, plain and simple. You give it your all every day and you hope that your hard work will be enough to support the business, and maybe one day, if you're lucky, your family too. There is no boss to guide you through decisions, there is no performance review to give you praise for a job well done. There is just the daily grind and the friendly faces of your regulars to get you through. Buying advertising is expensive and while it helps, nothing is more powerful than word-ofmouth within a community. > continued on next page
Ready to put your words to good use? Here are five tips to help you get started!

Eat Local – When trying to decide where to go for a meal, skip the big chain restaurants. Sure they are fun every now and then, but they are all the same nationwide. Why not make an investment in your community instead? Eat local! You will discover restaurants that are unique to Topeka and full of local culture. Share Your Experience - Love your meal? The atmosphere? Did you get outstanding service? These are all things that you can share with your friends and family on social media. Chances are, your photo will motivate someone else to visit the restaurant soon. Not sure how to share? Here are some tips.. •
Love the retro sign outside? Take a photo! Post it to Instagram, Facebook or whatever social network is your favorite.
•
Was that locally brewed beer amazing? Order another! Before you start on your second glass, take a photo of it with the angle just right to show off the great atmosphere in the background.
•
Did your server go above and beyond? Ask their permission and take a selfie with them! Tell everyone how great they are!
•
These are just a few tips to try, get creative and celebrate the experience of visiting this restaurant!
Be Their Biggest Fan – follow their Facebook page and tune into their posts. When they announce a special, share it! Tell everyone why you love the place so much and share link to their page. Nothing means more to a business owner than hearing how their customers love their product and sharing their posts helps them get the word out to a much bigger audience. Give Them a Review – An online review is a powerful thing for a small business for a couple of reasons. First and foremost, it lets the business owner know what they are doing right and what they are doing wrong. Your point of view is immensely valuable to them. Second, your review helps others learn about the restaurant. For people who are visiting from out of town or are curious to try something new, your words are a big help in their decision making process. So if you love a restaurant, take five minutes and go onto their Facebook page, Google or Yelp and leave them a review. It is one small step that has a huge impact. Don't Put Them On Blast – No matter how fantastic a place is, it is inevitable that someone is going to have a bad experience. It happens. It could have been a server with a bad attitude, or a new chef over cooking your food, sometimes things just go wrong. Please, if you have a bad experience, before you go public with your displeasure, talk to the manager or business owner. They will want to address the issue, not only for you but for future customers as well. Give them a chance to make things right before you force them to defend their business in a public forum. So that is it, you can make a huge impact on a small business just by telling your friends. It takes very little time and effort. Just remember, spreading the word about a small business is always in good taste. aseveneightfive

Just what is opportunity?
Colby and André are on the autism spectrum and Luke was born with Down Syndrome. All three participated in the special education program at Auburn-Washburn USD 437, which earned a shout out from André’s father, Luis Guillén. “André was in an awesome program. It helped him open up a lot.”
Opportunity is clearly different for different people. For three young men in Topeka, all with, in a parent’s words, “different abilities,” opportunity has a different face than for many of their peers. But thanks to an collaborated effort by family and friends, Colby Myers, André Guillén and Luke Gerhardt will have the opportunity to enjoy personal success All three earned a high school and meaningful employment through diploma and are currently enrolled in the special education program their lifetime. that allows them to continue their They will achieve this dream through an work on building life skills until amazing indoor field of greens. their 21st birthdays.

Marisol Guillén, and Tim and About one in every 66 children born in the US is diagnosed with autism, but the severity ranges across a wide spectrum. About one in every 700 children born in the US is born with Down Syndrome.

Greens and hydroponics
A state of the art, 5,400 square foot green house located south of Washburn Rural High School allows for a variety of greens to be grown hydroponically and harvested year around. And that’s what the three families do: plant, nurture, harvest, market, and deliver huge amounts of fresh greens to markets in Topeka, including Guillén’s restaurant, Luis’ Place, Lawrence and as far as Kansas City and Wichita.
The 2000 plants a week that come out of the greenhouse are grown in a network of high density polyethylene channels, dependent on pumps and computers using Topeka city water, delivered by RWD #3, which is treated to meet a strict PH balance. That’s it. No soil, no fertilizers, no pesticides. All pest control is done without chemicals.
The green house, located on land owned by the Gerharts, was finished and outfitted with the sophisticated network of computers, water storage and pumps, and plastic trays and troughs used in the process - in time for planting the first seeds. The first harvest started last January. An earlier visit by Luke to relatives in Wichita set in motion the idea to become hydroponic farmers. As part of developing job skills, all three young men, after filling out job applications, were put on the CALCan payroll. All three young men participate in the regular tasks: seeding, transplanting, harvesting and maintenance. The families’ work in the greenhouse centers around three days: Tuesdays, Wednesdays and Saturdays. Those days all three families, including André’s and Colby’s sisters, Alyssa Guillén and Sydney Myers and Luke’s cousin, Brooke Schucknecht, are at the greenhouse seeding, transplanting and harvesting. Prior to work, all involved enjoy a meal together, which is considered an essential element of the families’ efforts.
where to buy calcan products
The process, from planting to harvest takes six to eight weeks: two weeks as seedlings, two weeks in the nursery, then two to four weeks in a finishing stage.
The business and looking ahead The families know they have to have a good product to make a profit, which is key to sustainability. In order to do so, lots of data pertaining to costs/ overhead, sales, and of particular importance, the man-hours the young men contribute to the production is being collected. If this model is to be replicated, others will need to have a thorough understanding of what a labor force with disabilities brings to the table and what others will need to contribute. They are looking at other models, such as expanding on their own, looking for partners, or taking the initiative to schools themselves, which would provide both a group of students seeking the opportunities as well as a group of consumers looking for fresh greens on the salad bar. Guillén offered up this assessment of their efforts to date, “Our families are here to provide a vehicle for their success, we’re just in the backseat enjoying the ride.” aseveneightfive

T
he wind is brisk, the air chill and calm. Night settles in like a blanket over a sleeping child and no one is aware of the epic battle about to ensue. This ninja strikes once, nay, twice more to infiltrate the establishments that will satiate a warrior’s appetite. Quinton’s is the first foe I will confront. My skills are honed, my blade is sharp, and my resolve is unwaivering... Atmosphere I enter undetected to find a warm, inviting, spacious establishment. I cross the floor to a comfy booth where I will be hidden in the shadows until it is my time to strike. Each table feels somewhat private in this place and I am alone with my thoughts. Friendliness I am greeted with a smile and a menu immediately. For a moment I am distracted from my mission, but I regain control of the situation and order. During my meal the waitress is attentive, friendly and accommodates my needs with ninja-like speed.
Ninja’s RecommendationCajun Fries and Grilled Cheese 36
Menu Quinton’s offers deli style fare, with enough variety to satisfy the pickiest of ninjas. Not overwhelming but plenty of choices, I make my selection and wait for my opponent’s next move.
Food Splendid flavor, well prepared, and portions that fill this ninja’s belly. The Peppercorn Ranch dipping sauce is an assault on my ninja tastebuds and the Grilled Cheese and Tomato Soup is surprisingly well executed for such a common dish. The bread is buttered to perfection, the soup creamy and warm on a cold fall night. Funds Quinton’s doesn’t break the bank for what you receive. For less than $12 I procure a meal and drink fit for the fiercest warrior. Lunch or dinner, Quinton’s is a perfect choice for the mightiest ninja’s needs. aseveneightfive

T
he small, locally owned brewpub on the West side of Lawrence by Clinton Lake is a 15 BBL brewery that averages just under 1,000 barrels a year and distributes draught beer throughout Kansas. Impressive. But for me, it's not the beer that gets me out to 23rd Street Brewery - it's the amazing food (and the off-leash dog park down the street at Clinton Lake is a bonus).
Their menu is filled with signature dishes: the Danny Manning Marsala Chicken, the 23rd Street Meatloaf (made from a blend of bison and beef), the London Phog Fish + Chips, the Hank Booth Burger (burger topped with bacon, caramelized onion, sautéed mushrooms, homemade BBQ sauce and cheddar cheese) and The Bill Shelf (made from scratch mac and cheese topped with buffalo chicken tenders). Once again, I go against the grain. Sure, all of these dishes are delicious, but the MVP for me is their New Orleans Style Fish. The blackened salmon is always cooked to perfection, medium and served on a bed of rice with their creamy, spicy Cajun sauce. This sauce is so good, if they filled Clinton Lake with it, I would swim daily. The recommended side is broccoli, which is fantastic, but their green beans are dynamite: crispy, seasoned fresh snap beans that rival a main entrée. Also notable are several of their appetizers. The Romos' Cheese on Bread is a mozzarella and provolone cheese blend, brick over toasted with fresh garlic Italian crust and seasoning and served with marinara and their signature roasted garlic dressing. Two appetizers perfect for sharing and forcing you to get a to-go box for your entrée are the 23rd St Deconstructed Guacamole, a plate of fresh avocado served sliced with pico de gallo, sea salt on the side and fresh lime, ready for you to dip - and the Naked Nachos (smartest appetizer I've seen ever) your regular nacho all stars, meat, cheese, jalapeños, black beans and black olives plus tomatoes and scallions all served in a bowl with a side of sour cream, salsa and chips. Now you can actually share nachos politely and still have every chip topped with nacho goodness, and even take it home. Brilliant. Check out 23rd Street Brewery for their beer or for their signature dishes - or for pretty much everything else on the menu. They are all winners. aseveneightfive 38

ake a 15-minute drive on KS-4 to Meridan and find yourself at Game Day Bar + Grill, a small town "Cheers" where you'll experience great food and meet two of the kindest people I've ever had the change to meet. Cheers, groans, beer and big screens - Game Day is the place to meet your buddies for wings, nachos and a full slab of football, baseball and basketball. Or come alone and count on finding a crowd to hang with, it doesn't matter what colors or logo you are wearing. I've had the privilege of knowing Jackie Kern Cummings for over 25 years and with that the opportunity to meet her husband, Nick, her two boys, Creston and Hayden. The Cummings have been foster parents for a number of years and always opened their home to many in need. Jackie is a former teacher at Topeka West where she coached volleyball and softball; Nick is a special education teacher at Effingham and football coach at Valley Falls High School. Jarron is a student and plays football at Emporia State University while Jaime is a senior at Highland park High School. The couple purchased the former Watering Hole in Meridan last January, closed for a month of renovations, changed the name and opened February 9. They patronized the Watering Hole and felt it was a diamond in the rough, so when they learned it was for sale, they knew it was their time to play entrepreneurial ball. Game Day highlights include outdoor seating, bands, during the summer participating as a stop in various fundraising motorcycle rides and food specials including $1 Taco Tuesday, $2 chili dog Wednesday and their Sunday favorite, the Hangover, a burger topped with egg, bacon, shredded cheese and hot sauce. Cheers! aseveneightfive

The ioctl interface have an ioctl that lets you get the config rom
too, which is what the lidb1394 juju backend uses when enumerating the
cameras, in other words, this part does not generate any IO.

Alas there doesn't seem to be a single strategy that yields the very
best performance with all existing cameras. Especially if
bus_info_block.max_rom == 0, you can only guess to which extent block
reads might work.
The ieee1394 driver does interpret the config ROM while reading it. It
tries to read it in chunks up to the size indicated by max_rom and falls
back to quadlet reads if it encounters any problems. I don't think we
honor the alignment restriction of block reads in case of max_rom == 1.
The firewire-core driver also interprets the config ROM while reading.
But it always only reads quadlets. The cost to do so is lower than with
ieee1394 because of gap count optimization, at least on 1394a only
buses. (1394b Beta only buses already have a low arbitration overhead;
only the transaction overhead of the hardware/ firmware/ OS remain.
Mixed 1394a and 1394b buses would profit from gap count optimization but
we don't do it if 1394b PHYs act as repeaters, because then it becomes
hard to figure out a suitable gap count.).
Note, if you are keen on getting also config ROM contents which are
located outside the 400...7ff range, you (a) have to interpret the ROM
and (b) can't entirely rely on firewire-core's config ROM cache.
(Firewire-core only looks into the 400...7ff range.) However, I don't
know if there are any IIDC devices out there with config ROM outside
that range. It seems unlikely.

Introduction
Routing is the first and foremost phenomenon in the ASP.NET MVC pipeline. Here, you will learn about routing, how it works, and its variants.
Background
Last week one of my friends asked this question: "Can we make our custom route with some constraints and what is attribute routing?" I am dedicating this article to him. I hope he will like this.
The topics to be covered are,
Routing
Routing is the first step in ASP.NET MVC pipeline. This is the replacement of the concrete, physical files used in the URLs. In other words, routing is the phenomenon in which controller and actions execute rather than the concrete physical files.
Why do we need routing?
Traditionally, the URL of the browser represents the physical file. A file can be HTML file, ASPX page etc. Let’s understand this traditional way,
This URL shows that first we go to “images” folder then access the “john.aspx” file having id is 2. Hence it is not the good way to expose your precious information to the URLs of the browser, so with these URLs sites can be hacked. As a result, Routing comes into action and solves this problem of the traditional file-based system. Implementation of routing starts with route table. The route table is a collection of all possible, correct routes that can be used to map the HTTP request URLs. Let’s understand RouteTable and the working of Routing in detail.
Routing is a pattern matching system that matches the incoming request to the registered URL patterns reside in the Route Table. When an ASP.NET MVC application starts, it registers patterns to the RouteTable to tell the routing engine to give a response to the requests that match these patterns. An application has only one RouteTable and it resides in the Application_Start event of Global.asax of the application. The routes are registered to the RouteConfig class that has the route URLs to be mapped and ignored in the application. Let's have a look at it,
The Global.asax file looks like,
The Figure is illustrating the working of routes and depicts how the routing engine processes URL requests and gives the response to the browser.
When the UrlRoutingModule finds a perfect matching route for the incoming URL from the RouteTable then Routing Engine forwards this request to RouteHandler. When it matches successfully, then IRouteHandler comes into action for that route and its GetHttpHandler() method is invoked. IRouteHandler is looking like this,
After finding the route successfully, ProcessRequest() method is invoked, as shown in the figure; otherwise if the requested URL doesn’t match with any pattern in the RoutTable then the user will be redirected to HTTP 404 error page.
Parts of a Route
When you are going to register the routes you have to use the overloaded version of the MapRoute method in the RouteConfig class. There are 6 overloaded versions of the MapRoute method, the last method having all parameters is explained below,
Above MapRoute method has the following parameters,
Let’s understand each!
Name of Route
First of all, I want to say, there are very ambiguous ideas in the community about Name of the Route. So I highly recommend reading this section carefully and please leave your comment about this because I have learned it myself. So, please correct me if I'm wrong.
The route that is registered in the RouteTable must have a unique name to differentiate from other routes. This name refers to a specific URL pattern in the RouteTable. The most important thing is that this name is only used for URL generation. Hence I concluded that Routing does not happen on the basis of Name, it happens on the basis of its URL pattern. In fact, URL pattern tells the UrlRoutingModule what to do with the request, not the name of the route. Then the question comes why it should be unique, it should be because of it the thing that creates uniqueness for the URL generation. Let’s understand it practically.
Student.cshtml
Index.cshtml
When we click on URL then it will direct us to View of Second Route.
As you can see, we pass the name of route “Second Route” in the ancher tag and while clicking it will redirect us to that route whose name is given in ancher tag.
So the conclusion is, route names are used for URL generation. If the route name is not unique then how UrlRoutingModule will know about the Second Route and it will throw a runtime error as shown below,
URL Pattern of the Route URL pattern of the route consists of literal values and variable placeholders. These variables are also called URL parameters. All these literal values and placeholders are separated by forwarding slash (/) and called Segments.
Literal means a “fixed” value and variable placeholder mean “replacement of some value”. In a URL pattern, you can define a placeholder with the help of curly braces {}. You can define more than one placeholders in a segment with the help of literal. For examples, see the figure.
Hence, if you want to add more than one placeholders in a segment then you have to use a literal between those placeholders.
Defaults of Route
When you define a route, you can assign defaults values for each segment of the URL, these default values come into action when no parameter is provided in the URL. You can set defaults values for the route by making the anonymous object of the RouteValueDictionary class.
Constraints to Route
Constraints are limitations on Route parameters. When you set any constraint to a route then if the URL consists of values that do not fulfill the constraint requirements then that route will not work. And request goes to route that has defaults parameters. You add constraints to route to ensure that it will work according to your application requirements. You will see its more detail on this topic.
Namespaces to the Route
You can set your own namespaces for the web application. Namespaces can be added into routes by making objects of RouteValueDictionary class. This parameter used when you want to redirect your URL to a specific controller having a specific namespace.
Default Route and Custom Route
The figure illustrates that a route is going to be registered in the RouteCollection (routes.RouteTable) having a unique name Defaults, a URL pattern in which controller, action, id all are placeholders, then there is a defaults property whose responsibility is to initialize the controller and action automatically if it doesn’t include the requested URL.
Custom Route
Let’s create a custom route to understand Routing. As we have HomeContoller and the Index action method. Let’s create another action method name as Student,
Now we have to create a custom route in RoutConfig class
Before going to execute the application I want to tell you a very crucial thing about Routing, that is, “Always define your routes from Specific to General”. In the above code, the default route is most general so it should be at the end of the RouteTable. And our most specific route is the first route that we defined earlier. Routing flow is as follows,
Now when you execute your application and write the URLs as given below then the output is as follows,
Query String has question mark sign (?) in its URL. But this way of passing data is not a good way because through this method your data can be exposed to the hackers or penetrators. Better than a query string, the way of passing data is:
What is the purpose of IgnoreRoute() method?
In the above code of RouteConfig class you can see the IgnoreRoute() method as shown below:
As you know, the URL pattern {controller}/{action}/{id} is handled by UrlRoutingModule by default. But the point of interest is if you want the RoutingModule to handle the above-mentioned pattern then you have to set the RouteExistingFiles property of the RouteCollection to true.
You can see in the above code, the datatype of RouteExistingFiles property is bool so it can be true or false. When it is true, then the RoutingModule will handle all the requests that match the defined URL pattern in RouteConfig class. Otherwise, when this property is set to false, UrlRoutingModule will never handle any request.
Now, the problem is, when you have set RouteExistingFiles property to true, routing module handle all the requests. But when you want to stop the access of some routes to the browser, then how can you do that?
This can be done by using IgnoreRoute() method. The ignoreroute method will stop accessing the routes defined in IgnoreRoute parameters. The method looks like,
This will ignore the specified URL route from the list of available routes in RouteTable.
Now in RouteConfig class, what does the following code means?
The above code of IgnoreRoute() shows that resource.axd files are ban for the access. The last point is, these .axd files are not present in our project, and these are reserved for HTTP handling.
How to apply constraints to Custom Route?
Constraints are limitations on Route parameters. When you set any constraint to a route then if the URL consists of values that do not fulfill the constraint requirements then that route will not work.
Let’s understand it in a practical way, suppose you want to limit the roll number of the student to only 5 digits, then how can you do that?
This can be done with the help of constraints. Let’s play with it.
As shown above, roll number digits must be 5. When we execute the following URL:
Output: Roll Number is 12345
@”\d{5}” has @ sign as prefix which is called verbatim literal. Its opposite and bad way is using Escape sequences. Escape sequences and their use is defined in figure below,
Let’s know about the difference between both:
As we can see verbatim literal gives us great readability. Hence in this way you can make your own constraints on your custom routes.
What is Attribute Routing?
Attribute routing is the new type of routing in ASP.NET MVC 5. According to the name Attribute Routing, one can suppose that this type of methodology will use Attribute to define routes. Yes!
Let’s understand it in detail.
Why do we need Attribute Routing?
First of all, look at our previous custom route
Now let’s move to use Attribute Routing.
First of all, you have to enable the access to attribute routing. So RouteConfig class becomes,
Now, let’s go into controller and take a look at its working. A [Route] attribute is used at the top of the action method.
Output is,
If you want to make a parameter optional in attribute routing then simply place a question mark at the end or parameter like below,
You may see that many routes have the same portion from its start, it means their prefixes are the same. For example:
Both the above URLs have the same prefix which is Home.
So, rather than repeatedly typing the same prefix, again and again, we use RoutePrefix attribute. This attribute will be set at the controller level. As shown below,
In the above code, RoutePrefix is set to controller level and on action methods, we don’t have to use Home prefix again and again. The output is as follows:
The second Route attribute at the top of controller sets the default value for an action method.
As you had seen in the routing section, we can set Name for the route. So,
Can we set the Name in attribute routing for specific URL?
Yes!
Here also the name is only for URL generation. We can set the name as,
The above code shows how can we set the name of the route in attribute routing. After reading the section of Route Names in convention-based routing, you can repeat the procedure of URL generation in this Route attribute.
As you had seen in routing section, we should create our routes from more specific to more general flow. Then how can we do that in attribute routing?
Can we set the preference of routes in attribute routing?
Yes! You have to use Order parameter in route attribute. Suppose we have a controller having two action methods named as First and Second. And they have Order parameter set to 1 and 2.
The action method will execute according to FCFS (First Come First Server) and its value can be from -2,147,483,648 to 2,147,483,647 (size of int).
When we run this code, our Second action method will execute because it has higher order.
But if no order is specified in the Route attribute then action methods will execute according to the order in which the routes are registered in the RouteTable.
As you had seen in the routing section, we can set constraints to the convention-based routing.
Can we set the constraints for attribute routing? If yes then how?
Yes! You can set the constraints in attribute routing. The syntax is as follows,
First of all, take a look at different constraints that can be used in attribute routing.

DBIx::Class::Manual::FAQ - Frequently Asked Questions (in theory).
How Do I:.
Install Catalyst::Model::DBIC::Schema from CPAN. See its documentation, or below, for further details.
Install DBIx::Class::Schema::Loader from CPAN, and read its documentation.
Look at the DBIx::Class::Manual::Example and come back here if you get lost.
Create your classes manually, as above. Write a script that calls "deploy" in DBIx::Class::Schema. See there for details, or the DBIx::Class::Manual::Cookbook.
Make sure you database supports Unicode and set the connect attributes appropriately - see "Using Unicode" in DBIx::Class::Manual::Cookbook. using one "load_namespaces" in DBIx::Class::Schema call.
Add the name of the schema to the table name, when invoking table, and make sure the user you are about to connect as has permissions to read/write all the schemas/tables as necessary.
There are a variety of relationship types that come pre-defined for you to use. These are all listed in DBIx::Class::Relationship. If you need a non-standard type, or more information, look in DBIx::Class::Relationship::Base.
This is called a
has_many relationship on the one side, and a
belongs_to relationship on the many side. Currently these need to be set up individually on each side. See DBIx::Class::Relationship for details.
Create a
belongs_to relationship for the field containing the foreign key. See "belongs_to" in DBIx::Class::Relationship.
Just create a
belongs_to relationship,.
Instead of supplying a single column name, all relationship types also allow you to supply a hashref containing the condition across which the tables are to be joined. The condition may contain as many fields as you like. See DBIx::Class::Relationship::Base.') and call
search on it. See "search" in DBIx::Class::ResultSet.()'})
Supply a list of columns you want to sort by to the
order_by attribute. See "order_by" in DBIx::Class::ResultSet.
as?
You a scalar reference:
->search({'created_time' => { '>=', \'yesterday()' } })
To search in two related tables, you first need to set up appropriate relationships between their respective classes. When searching you then supply the name of the relationship to the
join attribute.
Currently, DBIx::Class can only create join conditions using equality, so you're probably better off creating a
view in your database, and using that as your source. A
view is a stored SQL query, which can be accessed similarly to a table, see your database documentation for details.
To use an SQL function on the left hand side of a comparison you currently need to resort to literal SQL:
->search( \[ 'YEAR(date_of_birth) = ?',.
$result->discard_changes
Discarding changes and refreshing from storage are two sides of..
Set the shell environment variable
DBIC_TRACE to a true value.
For more info see DBIx::Class::Storage for details of how to turn on debugging in the environment, pass your own filehandle to save debug to, or create your own callback.
DBIx::Class runs the actual SQL statement as late as possible, thus if you create a resultset using
search in scalar context, no query is executed. You can create further resultset refinements by calling search again or relationship accessors. The SQL query is only run when you ask the resultset for an actual:.

How can I slice the array, avoiding duplicate values in each chunk?
Suppose I have this array:
a = [1,2,3,3,3,3,3,3,3,3,3,4,5,6,6,7,8,9,10,11]
a.each_slice (2) .to_a will generate pairs, but these pairs will contain non-unique values such as [3,3]. So I guess I am looking for some sort of unique_each_slice method.
I want to be able to shuffle this array until I get to the point where I have unique pairs of 2 (doesn't have to be 2, can be anything), for example (using 2 example)
[3, 1, 3, 7, 6, 3, 4, 5, 8, 3, 9, 3, 2, 3, 6, 3, 3, 11, 10, 3]
If you do each_slice (2) on this array, you get unique pairs:
[[3, 1], [3, 7], [6, 3], [4, 5], [8, 3], [9, 3], [2, 3], [6, 3], [3, 11], [10, 3]]
compared to the original where you have:
[[1, 2], [3, 3], [3, 3], [3, 3], [3, 3], [3, 4], [5, 6], [6, 7], [8, 9], [10, 11]]
with non-repeating pairs in each, like [3,3]
Another example, suppose I have:
a = [1,2,3,3,3,3,3,3,3,3,3,4,5,6,6,7,8,9,10,11,12,13,14,15,16,17]
Now, suppose there is some function a.unique_slices_of (3), I would get:
[[4, 16, 3], [1, 9, 3], [3, 6, 17], [3, 6, 10], [15, 3, 2], [3, 8, 12], [11, 3, 14], [7, 13, 3], [3, 5]]
By "unique slice" I mean a slice where the same number is not repeated twice: [1,2,3] is a unique slice, [3,1,3] is not.
So far, I have come up with the following method, which seems to take several iterations before everything turns out right:
class Array def unique_slices_of!(slices) loop do unique = true self.each_slice(slices) do |slice| if slice != slice.uniq self.shuffle! unique = false # so we know whether to loop again break end end break if unique # if unique didn't change, that means all slices were equal if unique == false then unique == true end # reset and start again end self end end
The main problem with my code is that a) I don't think I'm using some idiomatic Ruby method that can cut this process in half or more. b) Possibility of an infinite loop if the array simply cannot contain unique slices. I will probably need to use some combination theory here, but I'm not sure how.
source to share
a = [1,2,3,3,3,3,3,3,3,3,3,4,5,6,6,7,8,9,10,11]
You can check if slices are "unique":
a.each_slice(2).all?{|x| x == x.uniq}
So now you just shuffle until you get what you want:
a.shuffle! until a.each_slice(2).all?{|x| x == x.uniq}
The easiest way to avoid an infinite loop is
timeout
:
require 'timeout' # raise an error if it takes more than 1 second timeout(1){ a.shuffle! until a.each_slice(3).all?{|x| x == x.uniq} }
source to share
Unique sample combinations
If you are looking for something more idiomatic and if algorithm efficiency is not your main concern, you can try the following:
a = [1, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 5, 6, 6, 7, 8, 9, 10, 11] a.combination(2).reject { |pair| pair[0] == pair[1] }.sample(a.size / 2)
The main disadvantage of this approach is speed when a is large, because the combination of Array # will generate all possible combinations before you start down the results with Array # reject and Array # sample . However, for modest sized arrays, this certainly seems to be fast enough.
Evaluating Solution Performance
Routine testing shows that this is more than fast enough for modest-sized arrays. Consider:
require 'benchmark' a = [1, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 5, 6, 6, 7, 8, 9, 10, 11] Benchmark.measure do a.combination(2).reject { |pair| pair[0] == pair[1] }.sample(a.size / 2) end.to_s #=> " 0.000000 0.000000 0.000000 ( 0.000052)\n"
Even with 100,000 iterations, my system still only had 3,650299 seconds. This seems fast enough for practical use given your placed enclosure, but your mileage may vary.
Allowing Arbitrary Subarray Sizing
Comparing terms with a graph
In the comments, the OP asked if this could be generalized to winnow sub-arrays with 2, 3, or 4 elements each. Yes, with a little refactoring, although performance degrades as the number of items in combination increases. Consider:
array = [1, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 5, 6, 6, 7, 8, 9, 10, 11] element_size = 4 array.combination(element_size). reject { |element| element.map { |member| element.count(member) > 1 }.any? }. sample(array.size / element_size)
The desired element_size is used to determine the number of samples that are required dynamically. This has the side effect of discarding any partially filled arrays, eliminating the "saggy" elements you get with # each_slice .
The workhorse here is still the rejection method, which now iterates over each member of each submatrix using # count and rejects the elements that have # any? terms that appear more than once in this submatrix. Even with better variable names, this is a little more complicated than when we have a fixed element size, but it is definitely more flexible.
More readable (and slightly faster) comparison
With a hat tip to @pguardiario (see this linked answer ), you can shorten this a little more and make it more readable by only selecting sub-arrays where all members of the array are # uniq . For example:
array.combination(element_size). select { |subarray| subarray == subarray.uniq }. sample(array.size / element_size)
source to share
I have a solution that seems to work. The main idea is to distribute the elements with the maximum number of samples to the maximum possible number of fragments. Add a few
shuffle
to make them seem random.
class Array def unique_slices_of(slice_length) buf = [] arr = [] hash = Hash.new 0 self.each {|i| hash[i] += 1} sorted = hash.sort_by {|k, v| v}.reverse # sorted[][0] holds the element and sorted[][1] holds the count return nil if sorted[0][1] > ((self.length * 1.0) / slice_length).ceil index = 0 until sorted.length.zero? # Add element to buf and decrement count # if count == 0, remove the entry from sorted buf << sorted[index][0] sorted[index][1] -= 1 if sorted[index][1] == 0 sorted.delete_at index break if sorted.length == 0 index -= 1 end index = (index + 1) % sorted.length if buf.length == slice_length arr << buf.shuffle buf.clear index = 0 end end arr << buf.shuffle if buf.length > 0 arr.shuffle end end
Output:
[2) [ ].unique_slices_of(3)].unique_slices_of(
source to share
A non-random way to do it
The idea here is to put different values in bins. Then, if there are leftover bins:
- Order bins by size, biggest baskets first
- Make a snippet by taking a number for each of the first
max_slice_size
boxes
- Remove empty cells
Since each value within a slice is taken from a different bin, it is guaranteed that the slice will contain different values.
Code:
def slices_without_repeats(a, max_slice_size) slices = [] bins = a.group_by { |e| e }.values until bins.empty? bins = bins.sort_by(&:size).reverse slice_size = [max_slice_size, bins.size].min slice = slice_size.times.map do |i| bins[i].pop end slices << slice bins.reject!(&:empty?) if slice.size < max_slice_size && !bins.empty? raise ArgumentError, "An element repeats too much" end end slices end
This algorithm does not use sheer randomness. It uses Ruby's quicksort, which is unstable and can potentially exploit randomness (as when choosing pivot points).
Using:
a = [1,2,3,3,3,3,3,3,3,3,3,4,5,6,6,7,8,9,10,11] p slices_without_repeats(a, 2) # [[3, 6], [3, 9], [3, 7], [3, 2], [3, 6], # [3, 10], [3, 11], [3, 4], [1, 8], [3, 5]]
Determines when this is not possible:
p slices_without_repeats(a, 3) # An element repeats too much (ArgumentError)
And it handles the case where the last chunk is not full:
p slices_without_repeats([1, 2, 3, 3, 4, 4, 4], 3) # [[4, 3, 2], [4, 3, 1], [4]]
