On Thursday 26th, there was a joint meeting with the Mobile Web Best Practices group which gave us a chance to explore some of the issues surrounding mobileOK as it affects both groups. The chair presented a slide that he's been showing to various audiences that tries to show a vision of how DRs can fit into what happens on the Web now, particularly in terms of identifying sites that meet specified criteria. This generated discussion around the idea of blogging/linking to/supporting DRs as an aid to trust, particularly with respect to blog spam.
We then looked at the use cases. The POWDER use cases are being prepared for publication soon. These are based on those developed for the WCL-XG but need some revision. Particularly use case 1 which is "the mobileOK use case". Actions were assigned to make sure it is re-written and shared with MWBP before publication. The same use case can be re-phrased as 'the accessibility use case', the 'child protection use case' and the 'trust use case' — really it's the matching resources to delivery context/end user use case.
We looked at ways to codify that adherence to mobileOK Pro (the name for the upper level of mobileOK conformance) always implies adherence to mobileOK Basic. Essentially, one is a sub-class of the other. There was then what amounted to a preview of the discussion planned for the following day on resource grouping with some comment from BP. Test implementations of mobileOK will be important test implementations of POWDER, so there's a lot of overlap here.
An important part of the discussion was why mobileOK needs to be encoded
in POWDER? There are simpler ways of tagging resources. The reasoning is
that POWDER supports: 1) Independent certification of the claim to be
mobileOK; 2) Detail of the the result of each test (pass, fail or warn);
3) DRs can contain descriptions from any namespace and so can serve many
purposes. None of these would be true of, say
<meta name="mobileOK"
content="Basic" />
There was a discussion about whether a link/rel tag that points from a
resource to a DR should include, or be able to include, a hint of the
description that would be found in that DR. In other words, something
like
<link rel="POWDER mobileOK"… Thus an agent seeking mobileOK
information would know to follow the link. There are arguments for this,
particularly in terms of efficiency of processing. However, the
arguments against were felt to be stronger. These centre around the need
to go back and change all the link/rel tags every time you add a new
description to a DR. It was resolved therefore that we would NOT seek to
propose this, however, POWDER will define some queries that can be run
against a DR to determine whether a particular descriptive vocabulary is
used (such as mobileOK).
On a related theme, should we define a 'well-known location' for DRs? This was discussed, particularly in the light of the fact that POWDER is chartered to offer a solution to prevent this being necessary — not just for POWDER but for other protocols such as P3P and robots.txt. The resolution was that no, we will not specify a 'well known location' (or similar), but will rely on link/rel tags to point to DR files.
A discussion on the groups' timelines lead to an agreement that Mobile Web Best Practices should seek publication of the first working draft of its mobileOK Description Resources document simultaneously with POWDER's forthcoming Description Resources document. It is hoped that this will occur around July 2007 (both groups have f2f meetings scheduled that month although these will not be co-located).
Finally, MWBP asked that it be possible within a DR to refer to any checker used to make the claim of mobileOK conformance, whether or not that checker was available online or not.
We began the day by looking at the work of the Rule Interchange Format WG. This prompted a solid discussion of the pros and cons of the approach we've taken so far in wanting to define resource groups in terms of data to be processed versus coding the definition directly in rules. Several Rule languages are available (such as N3 Rules, SWRL etc.) but none is (yet) recognised as a full standard/Recommendation. The result of the discussion was that POWDER will define a resource group in terms of data but, importantly, will give examples of how these can be transformed into rules programmatically.
There was considerable discussion around our expected use of terms from the FOAF vocabulary. In particular, terms marked as "unstable" in that document. We are pleased to note that the ERT WG has had similar discussions as it affects EARL. We discussed the possibility of defining our own terms but agreed that a) it is, of course, much better to use existing vocabularies and b) that the FOAF vocabulary is actually pretty stable, even the terms that are marked as unstable. Therefore we resolved that we would seek to promote the stabilisation of relevant terms by the FOAF community. If these efforts prove unsuccessful by September, we will return to the subject and consider, reluctantly, creating our own terms.
A short discussion was held regarding the use cases as these will be discussed at length on the next telecon. However, new use cases are being drafted.
The bulk of the meeting was devoted to the resource grouping document and many resolutions were taken. In addition to giving as clear explanations as we are able, we will also define groups using set notation and talk in terms of 'sets of resources.' This should aid clarity of thinking and give the document more rigour. Further, we agreed that the grouping document shall be renamed to POWDER: Grouping of Resources and the short name we seek in the TR space is 'powder-resource-groups' (and you can bet that discussion wasn't over in 5 minutes!).
Set definition by IRIs will, of course, be supported. We need to check the details of this as it affects canonicalisation.
We then turned to the properties we plan to use for defining a set in
terms of URIs and URI components. Having resolved that a property like
hasScheme would take a string and imply a matching rule, we needed to
discuss which matching rule would be appropriate (
startsWith,
endsWith,
exact or
contains). Some terms were changed, some were added but we have
a list that will be shown in the next version of the document. N.B.
Non-Web URIs are covered by virtue of the hasURI property which allows a
Regular Expression to be matched against the full URI.
We then hit our first area where the group can't reach consensus: how the different properties should be combined. How do we encode a set definition as being resources on example.org OR example.net where the path starts with either foo or bar? 5 possible methods are under discussion.
Option 1: Multiple instances of the same property are combined with logical OR, different properties are combined with logical AND. Thus we would encode the example as:
>
For: this 'looks right' to some.
Against: It is rather vague and relies on several assumptions being made. Can't use OWL cardinality.
Option 2: All properties of Set are combined with logical AND but we introduce a new property and class that allows properties to be combined with OR thus:
<wdr:Set> <wdr:includes> <wdr:unionOf> <wdr:hasHost>example.org</wdr:hasHost> <wdr:hasHost>example.net</wdr:hasHost> </wdr:unionOf> </wdr:includes> <wdr:includes> <wdr:unionOf> <wdr:pathStartsWith>foo</wdr:pathStartsWith> <wdr:pathStartsWith>bar</wdr:pathStartsWith> </wdr:unionOf> </wdr:includes> </wdr:Set>
For: Logical, Sem-Web friendly.
Against: what a lot of processing!
Option 3: Properties are combined with logical AND but they take a white space separated list, members of which are combined with OR.
<wdr:Set> <wdr:hasHost>example.org example.net</wdr:hasHost> <wdr:pathStartsWith>foo bar</wdr:pathStartsWith> </wdr:Set>
For: compact, logical, can use OWL cardinality.
Against: Processing may be heavy.
Option 4: Allow multiple Scope statements in a DR and combine those with OR.
<wdr:WDR> <wdr:hasScope> <wdr:Set> <wdr:hasHost>example.org</wdr:hasHost> <wdr:pathStartsWith>bar</wdr:pathStartsWith> </wdr:Set> </wdr:hasScope> <wdr:hasScope> <wdr:Set> <wdr:hasHost>example.org</wdr:hasHost> <wdr:pathStartsWith>foo</wdr:pathStartsWith> </wdr:Set> </wdr:hasScope> <wdr:hasScope> <wdr:Set> <wdr:hasHost>example.net</wdr:hasHost> <wdr:pathStartsWith>foo</wdr:pathStartsWith> </wdr:Set> </wdr:hasScope> <wdr:hasScope> <wdr:Set> <wdr:hasHost>example.net</wdr:hasHost> <wdr:pathStartsWith>bar</wdr:pathStartsWith> </wdr:Set> </wdr:hasScope> ... </wdr:WDR>
For: Logically consistent. Maintains tight control on individual set
definition. Allows easy integration with sets defined by property. May
aid processing efficiency.
Against: Allows multiple scope statements so that the scope of a DR is not closed - others can publish additional scope statements. Thus security is dependent on recognising the source of the scope statements.
Option 5: None of the above — just use the Regular Expression property hasURI. Options 1 - 4 all use properties that match a string against a component of a URI. The hasURI property matches a RegEx against the whole thing so we could write our example as
<wdr:Set> <wdr:hasURI>^(([^:/?#]+):)?(//[^:/?#]+\.)*example\.(org|net)/(foo|bar)</wdr:hasURI> </wdr:Set>
For: Most sets are expected to be simple. If you need to write a complex
Set definition, you probably know Regular Expressions or know someone
who does (and they'd probably be written by machine anyway). So we can
decide that all properties in the Set should be combined with AND, use
OWL cardinality etc.
Against: Goes against some of the design goals in that it requires knowledge of Regular Expressions. Also, they are error prone which may lead to resources being included or excluded by mistake. Finally it can't work with sets defined by resource properties (see next topic).
End result — we will include these options in the first public working draft and seek feedback.
At the end of the meeting we discussed two further issues briefly.
A possible method to define a set by resource property is:
1 <wdr:Set> 2 <wdr:hasProperty> 3 <wdr:Property> 4 <ex:colour>red</ex:colour> 5 </wdr:Property> 6 <wdr:hasProperty> 7 <wdr:propLookUp rdf: 8 <wdr:method>HEAD</wdr:method> 9 <wdr:resultContains>#ff0000</wdr:resultContains> 10 </wdr:Set>
Lines 2 - 6 allow the DR creator to specify that the resources must be
red to be in the Set. Line 7 provides a URI that can be queried. This
can be to any service that returns a result, thus it doesn't specify
that a particular protocol must be used. It must support including the
URI of the candidate resource (i.e. the resource whose membership of the
set we are testing). Line 8 says that an HTTP HEAD request is
sufficient and line 9 says that if the response contains '
ff0000' then
the candidate resource is indeed red.
Very early days on this — lots to think about. One question that keeps coming up — do we actually need to support set definition by resource property? At present, any such section of the document should be considered as a 'feature at risk' in the W3C sense.
Finally, the group recognised a need to discuss support within POWDER for user-generated tags, probably drawing on SKOS.

[0.7.10] date field are not (correctly) handled
Versions: 0.7.10 (and 0.7.8) with Sencha Touch 2.1.1
Browser: Chrome 24 (Win8 / Desktop)
Severity: critical (data corruption)
Using 'syncstorage' proxy in store, it seems that date field value are not correctly sent to the remote server when synchronizing new records (date for updated records are not sync at all, but I will open a new ticket for this case). When re-importing remote data in "empty" local storage (e.g. after a first login on a new device), date values for imported records are invalids (empty objects {}). So I supposed that date data are definitively lost.
Test case (I modified the 'examples/touch/todo' example for this test case)
MyApp.model.Todo line 29 (changed the 'timestamp' field type to DATE)
PHP Code:
[...]
{
name: 'timestamp',
type: 'date'
}
[...]
PHP Code:
[...]
record.set("completed", (completed == 1));
record.set("timestamp", new Date());
[...]
PHP Code:
[...]
itemTpl: [
'<div class="completed{completed}">{task}-{timestamp}</div>'
],
[...]
Code:
DEBUG: Transport.send { "service":"SyncRpcService", "from":"device-**********", "msg":{ "method":"putUpdates", "args":[{ "dd":{"userId":"**********", "databaseName":"todos", "generation":"0", "version":2}, "rd":{"deviceId":"device-***********","replicaId":"b6"}, "csv":"b1-66754329-5.b3-67258192.b6-67444510-5", "updates":"[ [\"b6-67444510\",\"_oid\",\"b6-67444510\",\"b6-67444510\"], [\"task\",\"test2\",\"b6-67444510-1\"], [\"details\",\"test2\",\"b6-67444510-2\"], [\"completed\",false,\"b6-67444510-3\"], [\"timestamp\",{},\"b6-67444510-4\"], [\"id\",\"b6-67444510\",\"b6-67444510-5\"] ]" }], "corr-id":6 }, [...] }
- Login again and wait for sync: the list item will show title-[object Object]. Based on the SIO debug log, imported value for timestamp is {}:
Code:
DEBUG: SyncProxy.applyUpdate: (b6-67444510 . _oid = 'b6-67444510' @ b6-67444510) accepted, creating new record INFO: SyncProxy.applyUpdateToRecord: (b6-67444510 . task = 'test2' @ b6-67444510-1) accepted INFO: SyncProxy.applyUpdateToRecord: (b6-67444510 . details = 'test2' @ b6-67444510-2) accepted INFO: SyncProxy.applyUpdateToRecord: (b6-67444510 . completed = 'false' @ b6-67444510-3) accepted INFO: SyncProxy.applyUpdateToRecord: (b6-67444510 . timestamp = '{}' @ b6-67444510-4) accepted INFO: SyncProxy.applyUpdateToRecord: (b6-67444510 . id = 'b6-67444510' @ b6-67444510-5) accepted
Thank you for the detailed test case to re-produce. We are investigating and will get back to you as soon as we know more.
Hello,
As a general practice we have avoided using the date field type. Instead storing the date as either a number:
Code:
date.getTime()
We would recommend that you modify your code and not use the date field type with sync stores while we work on a better support for that field type.
In the examples we provide (todo and shared data sync) we use date.getTime() so that the values can be sorted relative to one another. If your timestamp is for display purposes only then you can either convert the number into a date object then format it or you can simply store the date as a pre-formatted string.
Hi Jason,
Thanks for your advises (can't find where in documentation you warn about not using date field?). I finished my app (JDI for the HTML5 contest) so I don't look for an alternative solution, I just want to share my experience with Sencha IO and help you to enhance it.
I started my project without SIO and use a local store. All my code was based on date manipulation and display (and it worked fine). When switching to SIO, I tried to use integer or string to deal with SIO limitations, but (after many hours of debug) I had to heavily hack my model and fix some of your code to get this to work.
I needed support for null date, not sure that integer field can support null with SIO and did not want to have this special case: if (field == 0) means null. Using string seems OK, but there was the sorting issue (my field should be sorted as date). To workaround this, I defined my own Ext.data.Types (based on the string one):
PHP Code:
Ext.data.Types.DATETIME = {
convert: function(value) {
return (value === undefined || value === null)
? (this.getAllowNull() ? null : '')
: String(value);
},
sortType: Ext.data.SortTypes.asDate,
type: 'datetime'
};
So yes, I know that date are not totally supported in SIO and that it's preferable to not use it. But I think that you should fix this and transparently support date (and null date). Now, I still have two other date related bugs to report, are you interested in it?
Hello,
Again thank you for your detailed feedback. We are working on a more robust fix for the date issue.
We don't cover the date issue in the documentation. I'll add it in the next release; assuming we don't fix the issue and provide full support for dates in sync stores. | https://www.sencha.com/forum/showthread.php?256842-0.7.10-date-field-are-not-(correctly)-handled&p=940090&viewfull=1 | CC-MAIN-2015-40 | refinedweb | 778 | 66.23 |
Firstly, you'll need the Gosu Lib. found HERE!
after you have that done. Create a folder for the project. then extract the Gosu folder (somewhere thats not in the project folder) then go into the Lib folder of gosu. copy "gosu.for_1_8.so", "gosu.rb" and "fmod.dll" into your project folder.
now. open up Notepad(or a texteditor of your choice) and put this code in:
require 'gosu' class GameWindow < Gosu::Window def initialize super(640, 480, false) self.caption = "Gosu Window" end def update end def draw end end window = Gamewindow.new window.show
now save it as main.rb and run.
now i shall explain what all this does.
require 'gosu'
this allows the ruby file to use Gosu's built in classes.
class GameWindow < Gosu::Window
creates a new class defined by the Gosu::Window class, allowing you to create a window.
def initialize super(640, 480, false) self.caption = "Gosu Window" end
when the GameWindow is created, it sets up a new window of 640 width and 480 hight, with a caption of Gosu window.
window = Gamewindow.new window.show
creates a new instance of the GameWindow class, then displays it on the screen.
if there are any problems feel free to ask.
the next part of this tut will show you how to create a sprite on the screen and move it using the arrow keys .. keep a look out

YADR? Please decode.
Personally, I don't think I'd mind putting that restriction on library
implementors. The fact that most names are available to users for use as
preprocessor macros is a much more serious restriction on implementors.

Gonzalo, although the “flat php” version works fine, the Symfony version doesn’t work for me( Symfony 2.2).
It seems like passing the api version in baseurl on container is worth. The error:
Client error response
[status code] 404
[reason phrase] Not Found
[url]
The parameters after “/” dissapear. I tried pass the version api on container also and doesn’t work.
Ok, after read the documentation I found the mistake. A “/” at the begining of statuses $twitterClient->get(‘/statuses/user_timeline.json’)
Cool!. This sunday was marked in my personal ToDoList to check the issue and it’s solved before start!. I thought the problem was related to the changes that Twitter has been doing this days in its api (it was a nighmare in another proyect)
I am traying to create a real time Symfony app using Ratchet library and I have already integrate ratchet in my symfony app but I have no idea how to start working with it I can’t find any tutorial or a small example about it. plz I nead you re help and that will be great if I can have just a small example to know how shoud I work with it
Symfony2 show me two errors.
InvalidArgumentException: There is no extension able to load the configuration for “twitter.config”. Looked for namespace “twitter.config”, found none
FileLoaderLoadException: Cannot import resource from “services.yml”. (There is no extension able to load the configuration for “twitter.config”. Looked for namespace “twitter.config”, found none)
That’s look like your yml file isn’t correct. You’re writing twitter.config at the same level of indentation than “parameters” (you missed the spaces before). “twitter.config” is a child of parameters. Symfony thinks that you’re trying to use a custom extension called “twitter.config” and it throws an error because it cannot find the extension.

C# Tips and Tricks
Local Type Inference
Local type inference was also the subject of another prior article, but again is worth mentioning here as it is very handy to have a solid understanding. You define variables with the var keyword and the compiler will figure out the type for you at compile time and replace it. It is great for results from query expressions as show in the example below. It may appear that it is untyped or even give the impression it is a variant. It is not. It is a strongly typed object whose type is set at compile time.
var i = 5;int i = 5;string[] words = { "cherry", "apple", "blueberry" };var sortedWords = from w in words orderby w
select w;
Object and Collection Initializers
Initializers introduce a concise syntax that combines object creation and initialization in a single step. It even allows for parentheses to be optional for paramaterless constructors as you'll see in the first line of the example below.
Point p = new Point { X=3, Y=99 };Student myStudent = new Student() { Name = "John Doe", Class = "Senior", School = "Carmel" };
Initializers work very well with constructors. The example below shows an instance where a parameterized constructor is called along with remaining properties initialized. The constructor should commonly take all of the parameters so it isn't an ideal setup, but it illustrates the point well.
class Customer{ public Customer(string customerKey) { ... } public string CustomerKey { get { ... } } public string ContactName { get; set; } public string City { get; set; }}var c = new Customer("MARKS"){ ContactName = "Mark Strawmyer", City = "Indianapolis"}
Extension Methods
Extension methods allow you to create new functionality on existing types. Even if the types are sealed. They are declared like static methods and called like instance methods. They are valid for use on interfaces or constructed types. The trailing sample code illustrates the use of extension methods to add a Triple and Half method on the decimal type.
static class ExtensionSample{ public static decimal Triple( this decimal d ) { return d*3; } public static decimal Half( this decimal d ) { return d / 2; }}decimal y = 14M;y = y.Triple().Half();
Extension methods can be a very powerful tool. They can also be a very annoying tool if not used with some care. You should consider a separate namespace to allow them to be optional to the other developers that may be working within your codebase. Resist the temptation to put them on all objects by extending the object class. For consistency you should also make them behave like other instance methods.
The following code sample illustrates very bad form that should not be practiced. The namespace is System, which means the scope of this extension is any code that comes in contact with it. It extends ALL objects. It also does not behave like a normal instance method. Normally calling an instance method on a null object would result in a NullReferenceException and not a Boolean true or false value. This is a code example of what is not advisable.
namespace System{ public static class MyExtensions { public static bool IsNull(this object o) { return o == null; } }}while (!myObject.IsNull()) { ... }
LINQ Performance Tip
I'm not going to cover much on LINQ here as those are articles in and of themselves. Here is a LINQ performance tip that I experienced first hand on a project. Consider carefully the use of Table.ToList().Find(). Table.Where() is commonly a better option. ToList().Find() returns all records from a table and then runs the filter in memory. Table.Where() is performed in SQL and returns only the rows requested.
An additional tip is there is a handy tool known as LINQPad that allows you to perform interactive queries of databases using LINQ. It is a code snippet IDE that will execute any C# expression or statement block, which is very handy for testing out LINQ.

My suggestion:
Create a small patcher that merges the diffs, like it has been suggested
before; But instead of doing this on individual files and shooting them
into the zip, just diff the full zip file.
Error Handling: When the 'installer' is patching, have it first move
files to .old, then apply the patches into the original filename,
followed by deleting the .old file. If the .old files exist on next app
startup, you can reverse the patching and start over.
I'd recommend making the main app (that is, the exe + the main py
script) the patcher itself; Have it check for updates on startup,
download & patch if an update is available, and then launch your actual
script.
A different solution is having the main app be a version checker and
downloader, that does all of the above except the actual patching, which
is managed by a patcher script downloaded with each version - that would
allow flexibility in your patching system.

Uggh, it looks like I accidentally sent the last part of my conversation
with myself to the ctypes list instead of the py2exe list...
Anyway, I finally have something I'm pretty happy with. There is nothing
extra in any of my python files except setup.py and a distribution is
produced which includes all the pyo files and no zip files. Here is
setup.py:
import os
from distutils.core import setup

echo $'\360\237\215\272'
or
echo $'\360\237\215\270' echo $'\360\237\215\271' echo $'\360\237\215\273' echo $'\360\237\215\274'

I am developing a C Sharp Word AddIn that acts the same as the File>Open option. The exception is that when I click on the AddIn, I want it to ask the user which file they want to open...
I have .NET Framework 4, Visual Studio 2010 and Word 2010.
Here is the code so far...
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Linq;
using Word = Microsoft.Office.Interop.Word;
using Office = Microsoft.Office.Core;
using Microsoft.Office.Tools.Word;
using System.IO;
namespace WordAddIn2
{
public partial class ThisAddIn
{
private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
System.Console.Write("Enter the file name: ");
String fileName = System.Console.ReadLine();
Microsoft.Office.Interop.Word.Application oWord = new Microsoft.Office.Interop.Word.Application();
Word._Document oDoc;
oDoc = oWord.Documents.Open(@"H:\SNH\" + fileName);
}
}
}
When I add the AddIn to Word and try to run it, it produces an error saying "This file could not be found." However, it was supposed to ask the user which file to open and never did.
You are going to have to create a Windows.Form (or use WPF) and present it to the user. Currently you are using the console and that won't work.

Here we will see how to get the sum of elements from index i to index j in an array. This is basically the range query. The task is easy by just running one loop from index i to j, and calculate the sum. But we have to care about that this kind of range query will be executed multiple times. So if we use the mentioned method, it will take much time. To solve this problem using more efficient way we can get the cumulative sum at first, then the range sum can be found in constant time. Let us see the algorithm to get the idea.
begin c_arr := cumulative sum of arr if i = 0, then return c_arr[j]; return c_arr[j] – c_arr[i-1] end

ETD Guide/Technical Issues/SGML\XML and Other Markup Languages
SGML (Standard Generalized Markup Language) and XML (eXtensible Markup Language) are markup languages, which use tags ("<" and ">") with names of labels inside around the sections of the documents that are thus marked or bracketed. Document Type Definition (DTD) specifies the grammar or structure for a type or a class of documents. SGML requires a DTD while XML employs DTD optionally. But given current trends it seems that XML is most likely to be used due to the following reasons.
- XML is a method for putting structured data in a text file for "structured data" think of such things as spreadsheets, address books, configuration parameters, financial transactions, technical drawings, etc. Programs that produce such data often also store it on disk, for which they can use either a binary format or a text format. The latter allows you, if necessary, to look at the data without the program that produced it. isn't HTML
Like HTML, XML makes use of tags and attributes (of the form name="value"), but. In short it allows you to develop your own mark up language specific to a particular domain.
- XML documents can be preserved for a long time.
XML is, at a basic level an incredibly simple data format. It can write in 100 percent pure ASCII text as well as in a few other well-defined formats. ASCII text is reasonably resistant to corruption. Also XML is very well documented. The W3C’s XML 1.0 specification tells us exactly how to read XML data.
- XML is license-free, platform-independent and well-supported.
By choosing XML as the basis for some project, you buy into a large and growing community of tools (one of which may already do what you need!) and engineers experienced in the technology. Opting for XML is a bit like choosing SQL for databases: you still have to build your own database and your own programs/procedures that manipulate it, but there are many tools available and many people that can help you. And since XML, as a W3C technology, is license-free, you can build your own software around it without paying anybody anything. The large and growing support means that you are also not tied to a single vendor. XML isn't always the best solution, but it is always worth considering.
- which describes a standard way to add hyperlinks to an XML file. XPointer & XFragments. XML Schemas help developers to precisely define their own XML-based formats. There are several more modules and tools available or under development.
- XML provides Structured and Integrated Data XML is ideal for large and complex data like ETD’s because data is structured. It not only lets you specify a vocabulary that defines the elements in the document; but it also allows you to specify relations between the elements.
- XML can encode metadata about DTD’s.
Documents are often supplemented with metadata (that is data about data). If such metadata were included inside an ETD then it would make ETD self-describing. XML can encode such metadata. However on the downside XML comes with its own bag of discomforts.
- Conversion from word processing forms to XML requires more planning is advance, different tools and broader learning about processing concepts than it is required for PDF.
- There are many fewer people knowledgeable about these matters and tools that support this conversion are less mature and expensive. Also process of converting may be complicated, difficult and time consuming.
- Writing directly in XML by using XML authoring tools requires some prior knowledge of XML.
- Also XML is very strict regarding the naming and ordering of tags. It is also case sensitive illustrating the relative effort required by students to prepare ETD’s in this form.
Process of Creating an XML document
XML documents have four-stage life cycle.
XML documents are mostly created using an editor. It may be a basic text editor like notepad. or .vi. editor. We may even use WYSIWYG editors. The XML parser reads the document and converts it into a tree of elements. The parser passes the tree to the browser that displays it. It is important to know that all this processes are independent and decoupled from each other.
Putting XML to work for ETD’s Before we jump into the XML details for ETD.s we should make certain things clear, since we would be using them on a regular basis now onwards.
DTD (Document Type Definition):
An XML document primarily consists of a strictly nested hierarchy of elements with a single root. Elements can contain character data, child elements, or a mixture of both. The structure of the XML document is described in the DTD. There are different kinds of documents like letter, poem, book, thesis, etc. Each of the documents has its own structure. This specific structure is defined in a separate document called Document Type Definition (DTD).
DTD used is based on XML and it covers most of the basic HTML formatting tags and also some specific tags from the Dublin core metadata. A DTD has been developed for ETD. The developed DTD is too generic. If someone wants to use mathematical equation or incorporate some chemical equation, it won't be sufficient. For that we can incorporate MathML (Mathematical Markup Language) and/or CML (Chemical Markup Language). There are defined DTDs for these languages that we also have to use for our documents. But research of incorporating more that one DTD for different parts of the documents is still going on.
CSS (Cascaded Style Sheets):
CSS is a flexible, cross-platform, standards-based language used to suggest stylistic or presentational features applied throughout entire websites or web pages. In their most elegant forms, CSS are specified in a separate file and called from within the XML or HTML header area when documents loads into the CSS-enabled browser. Users can always turn off the author's styles and apply their own or mix their important styles with the authors. This points to the "cascading" aspect of CSS.
CSS is based on rules and style sheets. A rule is a statement about one stylistic aspect of one or more elements. A style sheet is one or more rules that apply to a markup document.
An example of a simple style sheet is a sheet that consists of one rule. In the following example, we add a color to all first-level headings (H1). Here's the line of code - the rule - that we add:
H1 {color: red}
XSL (the eXtensible Stylesheet Language):
XSL is a language for expressing stylesheets. It consists of two parts:
- A language for transforming XML documents, and
- An XML vocabulary for specifying formatting semantics.
If you don't understand the meaning of this, think of XSL as a language that can transform XML into HTML, a language that can filter and sort XML data, a language that can address parts of an XML document, a language that can format XML data based on the data value, like displaying negative numbers in red, and a language that can output XML data to different devices, like screen, paper or voice. XSL is developed by the W3C XSL Working Group whose charter is to develop the next version of XSL.
Because XML does not use predefined tags (we can use any tags we want), the meanings of these tags are not understood: could mean an HTML table or maybe a piece of furniture. Because of the nature of XML, the browser does not know how to display an XML document. In order to display XML documents, it is necessary to have a mechanism to describe how the document should be displayed. One of these mechanisms is CSS as discussed above, but XSL is the preferred style sheet language of XML, and XSL is far more sophisticated and powerful than the CSS used by HTML. XML NamespacesThe purpose of XML namespaces is function of XML namespaces.
- XML namespaces are declared with an xmlns attribute, which can associate a prefix with the namespace. The declaration is in scope for the element containing the attribute and all its descendants. For example code below declares two XML namespaces. Their scope is the A and B elements:
<A xmlns:abcd</A>
- If an XML namespace declaration contains a prefix, you refer to element type and attribute names in that namespace with the prefix. For example code below declare A and B, code below is same as previous example but uses a default namespace instead of foo prefix:
<A xmlns=""><B>abcd</B></A>
Glossary
attribute
XML structural construct. A name-value pair within a tagged element that modifies certain features of the element. For XML, all values must be enclosed in quotation marks.
cascading style sheets (CSS)
Formatting descriptions that provide augmented control over presentation and layout of HTML and XML elements. CSS can be used for describing the formatting behavior of simply structured XML documents, but does not provide a display structure that deviates from the structure of the source data.
CDATA section
XML structural construct. CDATA sections can be used to mark tags or reserved characters with quotation marks and thus prevent them from being interpreted. For this reason, the CDATA section is especially useful for escaping markup and script. The syntax for CDATA sections in XML is <![CDATA[ ... ]]>.
character data
XML structural construct. The text content of an element or attribute. XML differentiates this plain text from markup.
character set
A mapping of a set of characters to their numeric values. For example, Unicode is a 16- bit character set capable of encoding all known characters; it is used as a worldwide character-encoding standard.
component
An object that encapsulates both data and code, and provides a well-specified set of publicly available services.
data type
The type of content that an element contains: a number, a date, and so on. In XML, an author can specify an element's data type, for example, with a tokenized attribute type. Microsoft is working with the W3C to define a set of standard types that anyone can freely use.
document element
The top-level element of an XML document; only one top-level element is allowed. The document element is a child of the document root.
Document Object Model (DOM)
The standard maintained by the W3C that specifies how the content, structure, and appearance of Web documents can be updated programmatically with scripts or other programs. The proposed object model for XML matches the Document Object Model for HTML so that script writers can easily learn XML programming. The XML DOM will provide a simple means of reading and writing data to and from an XML tree structure.
document root
The top-level node of an XML document; its descendants branch out from it to form the XML tree for that document. The document root contains the document element and can also contain a set of processing instructions and comments.
document type declaration
XML structural construct. A production within an XML document that contains or points to markup declarations that provide a grammar for a class of documents. This grammar is known as a Document Type Definition. The document type declaration can point to an external subset (a special kind of external entity) containing markup declarations, or can contain the markup declarations directly in an internal subset, or both. The DTD for a document consists of both subsets taken together. The syntax of the document type declaration is <!DOCTYPE content >.
Document Type Definition (DTD)
The markup declarations that describe a grammar for a class of documents. The DTD is declared within the document type declaration production of the XML file. The markup declarations can be in an external subset (a special kind of external entity), in an internal subset directly within the XML file, or both. The DTD for a document consists of both subsets taken together.
Electronic Data Interchange (EDI)
An existing format used to exchange data and support transactions. EDI transactions can be conducted only between sites that have been specifically set up with compatible systems.
element
XML structural construct. An XML element consists of a start tag, and end tag, and the information between the tags, which is often referred to as the contents. Elements used in an XML file are described by a DTD or schema, either of which can provide a description of the structure of the data.
entity
XML structural construct. A character sequence or well-formed XML hierarchy associated with a name. The entity can be referred to by an entity reference to insert the entity's contents into the tree at that point. The function of an XML entity is similar to that of a macro definition. Entity declarations occur in the DTD.
entity reference
XML structural construct. Refers to the content of a named entity. The name is delimited by the ampersand and semicolon characters; for example, &bookname; and <. It is used in much the same way as a macro.
Extensible Linking Language (XLL)
An XML vocabulary that provides links in XML similar to those in HTML but with more functionality. Linking could be multidirectional, and links could exist at the object level rather than just at a page level.
Extensible Markup Language (XML)
A subset of SGML that provides a uniform method for describing and exchanging structured data in an open, text-based format, and delivers this data by use of the standard HTTP protocol. At the time of this writing, XML 1.0 is a World Wide Web Consortium Recommendation, which means that it is in the final stage of the approval process.
Extensible Stylesheet Language (XSL)
A language used to transform XML-based data into HTML or other presentation formats, for display in a Web browser. Differs from cascading style sheets in that it can present information in an order different from that in which it was received. XSL will also be able to generate CSS along with HTML. XSL consists of two parts, a vocabulary for transformation and the XSL Formatting Objects.
ID
A special attribute type within the XML language. The ID attribute on the XML element provides a unique name, enabling links to that element using the IDREF attribute type. The value associated with the ID attribute must be unique within that XML document. IDs are currently declared with a DTD or schema.
markup
XML structural construct. Text in an XML document that does not represent character data: start tags, end tags, empty-element tags, entity references, character references, comments, CDATA section delimiters, DTDs, and processing instructions.
mixed content
XML structural construct. An element type has mixed content when elements of that type can contain character data, optionally interspersed with child elements. In this case, the types of the child elements can be constrained, but not their order or their number of occurrences.
namespace
A mechanism to resolve naming conflicts between elements in an XML document when each comes from a different vocabulary; it allows the commingling of like tag names from different namespaces..
NDATA
The literal string "NDATA" is used as part of a notation declaration. See also notation.
notation
Usually refers to a data format, such as BMP. A notation identifies by name the format of unparsed entities, the format of elements that bear a notation attribute, or the application to which a processing instruction is addressed.
notation declaration
A notation declaration provides a name and an external identifier for a notation. The name is used in entity and attribute-list declarations and in attribute specifications. The external identifier is used for the notation, which can allow an XML processor or its client application to locate a helper application capable of processing data in the given notation.
processing instruction (PI)
XML structural construct. Instructions that are passed through to the application. The target is specified as part of the PI. The syntax for a PI is <?pi-name content?>.
Resource Definition Framework (RDF)
An object model similar in function to an application programming interface (API), RDF can be used by developers to access the logical meaning of designated content in XML documents.
root element
Sometimes this term is used to refer to the document element but this is misleading, since the top-level element and the document root are not the same. Because of this ambiguity, use of the term "root element" is discouraged.
schema
A formal specification of element names that indicates which elements are allowed in an XML document, and in which combinations. A schema is functionally equivalent to a DTD, but is written in XML; a schema also provides for extended functionality such as data typing, inheritance, and presentation rules.
Standard Generalized Markup Language (SGML)
The international standard for defining descriptions of structure and content of electronic documents. XML is a subset of SGML designed to deliver SGML-type information over the Web.
target
The application to which a processing instruction is directed. The target names beginning with "XML" and "xml" are reserved. The target appears as the first token in the PI. For example, in the XML declaration <?xml version="1.0"?>, the target is "xml".
text markup
Inserting tags into the middle of an element's text flow, to mark certain parts of the element with additional meta-information.
tokenized attribute type
Each attribute has an attribute type. Seven attribute types are characterized as tokenized: ID, IDREF, IDREFS, ENTITY, ENTITIES, NMTOKEN, and NMTOKENS.
Uniform Resource Identifier (URI)
The generic set of all names and addresses that refer to resources, including URLs and URNs. Defined in Berners-Lee, T., R. Fielding, and L. Masinter, Uniform Resource Identifiers (URI): Generic Syntax and Semantics. 1997. See updates to the W3C document RFC1738. The Layman-Bray proposal for namespaces makes every element name subordinate to a URI, which would ensure that element names are always unambiguous.
Uniform Resource Locator (URL)
The set of URI schemes that have explicit instructions on how to access the resource on the Internet.
Uniform Resource Name (URN)
A Uniform Resource Name identifies a persistent Internet resource.
valid XML
XML that conforms to the vocabulary specified in a DTD or schema.
W3C
World Wide Web Consortium
well-formed XML
XML that meets the requirements listed in the W3C Recommendation for XML 1.0: It contains one or more elements; it has a single document element, with any other elements properly nested under it; each of the parsed entities referenced directly or indirectly within the document is well-formed. A well-formed XML document does not necessarily include a DTD.
World Wide Web Consortium (W3C)
The international consortium founded in 1994 to develop standards for the Web. See
XLL
Extensible Linking Language
XML
Extensible Markup Language
XML declaration
The first line of an XML file can optionally contain the "xml" processing instruction, which is known as the XML declaration. The XML declaration can contain pseudoattributes to indicate the XML language version, the character set, and whether the document can be used as a standalone entity.
XML document
A data object that is well-formed, according to the XML recommendation, and that might (or might not) be valid. The XML document has a logical structure (composed of declarations, elements, comments, character references, and processing instructions) and a physical structure (composed of entities, starting with the root, or document entity).
XML parser
A generalized XML parser reads XML files and generates a hierarchically structured tree, then hands off data to viewers and other applications for processing. A validating XML parser also checks the XML syntax and reports errors.

With the polymorphism Java can
Suppose that you're developing an application.
You start by creating a class named Player that represents one of the players.
This class has a public method named move() that returns an int to indicate which square of the board the player wants to mark:
class Player { public int move() { for (int i = 0; i < 9; i++) { System.out.println("\nFrom Basic:");.
Now you need to create a subclass of the Player class that uses a more intelligent method to choose its next move:
class BetterPlayer extends Player { public int move() { System.out.println("\nFrom Better:"); return findBestMove(); } private int findBestMove() { int square = 0; // code to find the best move goes here return square; } }
As you can see, this version of the Player class overrides the move method and uses a better algorithm to pick its move.
The next thing to do is write a short class that uses these two Player classes to play a game.
This class contains a method named playTheGame() that accepts two Player objects.
It calls the move method of the first player and then calls the move method of the second player:
public class Main { public static void main(String[] args) { Player p1 = new Player(); Player p2 = new BetterPlayer(); //type is Player playTheGame(p1, p2); } public static void playTheGame(Player p1, Player p2) { p1.move(); p2.move(); //calling method from BetterPlayer } }
Notice that the playTheGame() method doesn't know which of the two players is the basic player and which is the better player.
It simply calls the move method for each Player object.
When you run this program, the following output is displayed on the console:
From Basic: From Better:
When the move method for p1 is called, the move method of the Player class is executed.
But when the move method for p2 is called, the move method of the BetterPlayer class is called.
Java knows to call the move method of the BetterPlayer subclass because it uses a technique called late binding.
During Late binding the compiler can't tell for sure what type of object a variable references, it doesn't hard-wire the method calls when the program is compiled. Instead, it waits until the program is executing to determine exactly which method to call.PreviousNext | https://www.demo2s.com/java/java-class-polymorphism.html | CC-MAIN-2021-04 | refinedweb | 382 | 63.73 |

But then right motor speed would be faster,
so left motor have to ++.

Java ping FAQ: How do I ping a computer from a Java program (or Java class, or Java method)?
I've been working on a new Java networking application, and as part of network debugging, I wanted to be able to ping a server from my Java program. I thought writing a “Java ping” class/program would be straightforward, but in short, it wasn’t, so I wrote a little helper class to let me call the operating system
ping command, and use the output from it. (Not what I wanted, but it works.)
I'm not going to get into the discussion too much today, as I'm still working on this class, so without much introduction, here's the source code for a Java ping class I've created. This class lets me ping other servers/hosts from my Java application, using the ping command from the host operating system. In my case, I'm using Mac OS X 10.5, so I'm using the Mac ping command, which is located in the
/sbin directory.
My Java ping class (program) source code
Here's the source code for my JavaPingExampleProgram:
import java.io.*; import java.util.*; /** * A Java ping class. * Created by Alvin Alexander, devdaily.com. */ public class JavaPingExampleProgram { public static void main(String args[]) throws IOException { // create the ping command as a list of strings JavaPingExampleProgram ping = new JavaPingExampleProgram(); List<String> commands = new ArrayList<String>(); commands.add("/sbin/ping"); commands.add("-c"); commands.add("5"); commands.add(""); ping.doCommand(commands); } /** * Provide the command you want to run as a List of Strings. Here's an example: * * List<String> commands = new ArrayList<String>(); * commands.add("/sbin/ping"); * commands.add("-c"); * commands.add("5"); * commands.add(""); * exec.doCommand(commands); * * @param command The command you want to execute, provided as List<String>. * @throws IOException This exception is thrown so you will know about it, and can deal with it. */ public void doCommand(List<String> command) throws IOException { String s = null; ProcessBuilder pb = new ProcessBuilder(command); Process process = pb.start(); BufferedReader stdInput = new BufferedReader(new InputStreamReader(process.getInputStream())); BufferedReader stdError = new BufferedReader(new InputStreamReader(process); } } }
As I mentioned, this Java ping class is still a work in progress, but it does work. As the main method shows, you can ping a network host like by creating your system command as a List of String objects. The command shown in the code would look like this if issued on the command line:
/sbin/ping -c 5
Java ping class/program and InetAddress
As a final note before leaving today, I thought I'd be able to accomplish this task using the isReachable method of the InetAddress class, but that method didn't work as expected. For instance, while I am able to ping from the command line, the isReachable method returns
false when I try to access the same hostname. Therefore, I created my own Java ping program, as shown above.
Okay, one more final note: As you might guess from my Java ping class/program, I'm actually working to make this class more generic, so I can easily run any system command. Running the command is easy, but trying to determine what to do with standard output and standard error streams requires a little more thought, especially if you want to run your commands from a Java GUI app, and display the output in real time in the GUI. | https://alvinalexander.com/java/java-ping-class/ | CC-MAIN-2022-05 | refinedweb | 570 | 59.13 |
Hello,
I have an enum defined as follows
public enum EnumStuff {
Value1 = 1,
Value2 = 2,
Value3 = 3
}
I am trying to retrieve the name as well as the value from each value inside of this enum. However, I have tried the following and it does not work.
public class Test {
public static void Main(String[] args) {
EnumStuff es = EnumStuff.Value1
Type t = e.GetType();
FieldInfo[] fi = t.GetFields();
foreach (FieldInfo i in fi) {
Console.WriteLine("Name: " + i.Name);
Console.WriteLine("Value: " + i.GetValue(es));
}
}
}
Instead of printing the value, it prints the name of the variable. Is there a way to display both the name and the value for each variable in the enum?
Thank you for your help | http://forums.devshed.com/net-development-87/reflection-95688.html | CC-MAIN-2015-06 | refinedweb | 119 | 76.22 |
Now that we have a good understanding of all the API calls we need to make, we can start setting up the project.
I'll be building this project as a Node project simply because it's the lowest overhead and easy to host somewhere.
The goal for today is to have a basic Node project that we can run. On running the code, it should list all unsubscribed people from Revue and all the subscribers.
Creating the project
Let's get started.
Create a new node project.
# Create folder mkdir revue-sendy-sync # Navigate into the folder cd revue-sendy-sync # Init new node project npm init
We should now have our basic project with a
package.json file.
The first thing I did was change it to module type so we can use imports.
{ "name": "revue-sendy-sync", "version": "1.0.0", "type": "module", ... }
The next thing we want to do is add some packages that we'll use. So far, we know we need some environment variables and want to make some API calls.
The packages we can use for that are
dotenv and
node-fetch.
npm i dotenv node-fetch
With those installed, we can define a
.env file. This file can be used to store your environment variables.
While creating this, also make sure to exclude it by using your
.gitignore file. (You don't want your secret to being committed to git!)
Inside the
.env file, add the following variable.
REVUE_API_TOKEN={YOUR_TOKEN}
Note: Don't have the token? Read the article on retrieving all the API keys.
Then the last file we need is an
index.js file. This will be the brains of the operation.
Create the file, and start by importing the packages we installed.
import dotenv from 'dotenv'; import fetch from 'node-fetch'; dotenv.config(); console.log(`I'm working!`);
You can now try to run this by executing
node index.js. In return it should show you "I'm working".
Calling the Revue API from Node.js
Let's start with the first piece of software. We want to be able to call the Revue API.
We can start with the unsubscribe call.
To make things scaleable, I created a custom function for this purpose.
const getRevueUnsubscribers = async () => { const response = await fetch( '', { headers: { Authorization: `Token ${process.env.REVUE_API_TOKEN}`, 'Content-Type': 'application/json', }, method: 'GET', } ).then((res) => res.json()); return response; };
As you can see, we use the
node-fetch package to request the unsubscribed endpoint. We then pass the
Authorisation header where we set the API token.
Note: This token is loaded from our
.envfile.
Once it returns, we convert the response to a valid JSON object and eventually return that.
Then we have to create a function that runs once our script gets called. This is called an Immediately invoked function expression (IIFE for short).
(async () => { const revueUnsubscribed = await getRevueUnsubscribers(); console.log(revueUnsubscribed); })();
This creates a function that invokes itself, so it will now run when we run our script.
In return, it will console log the JSON object of people who unsubscribed on Revue.
Yes, that was more straightforward than I thought. We already have one call done.
Let's also add the call that will get the subscribed people.
const getRevueSubscribers = async () => { const response = await fetch('', { headers: { Authorization: `Token ${process.env.REVUE_API_TOKEN}`, 'Content-Type': 'application/json', }, method: 'GET', }).then((res) => res.json()); return response; };
And we can add this to our IIFE like this.
(async () => { const revueUnsubscribed = await getRevueUnsubscribers(); console.log(revueUnsubscribed); const revueSubscribed = await getRevueSubscribers(); console.log(revueSubscribed); })();
Let's try it out and see what happens.
Nice, we can see both API calls return data.
Cleaning up
For those paying attention, we created some repeating code. The Revue API calls look the same, so we can change things around a little bit.
const callRevueAPI = async (endpoint) => { const response = await fetch(`{endpoint}`, { headers: { Authorization: `Token ${process.env.REVUE_API_TOKEN}`, 'Content-Type': 'application/json', }, method: 'GET', }).then((res) => res.json()); return response; }; (async () => { const revueUnsubscribed = await callRevueAPI('subscribers/unsubscribed'); console.log(revueUnsubscribed); const revueSubscribed = await callRevueAPI('subscribers'); console.log(revueSubscribed); })();
The code still does the same thing, but now we only leverage one uniform function.
It only limits to
GET requests, but for now, that's precisely what we need.
Conclusion
This article taught us how to call the Revue API from NodeJS.
If you want to follow along by coding this project yourself, I've uploaded this version to GitHub.
We'll call the Sendy API in the following article, so keep an eye! | https://h.daily-dev-tips.com/revue-sendy-sync-project-setup-revue-calls | CC-MAIN-2022-33 | refinedweb | 757 | 68.77 |
Replace cd E:www80curl with cd /d E:www80curl (or just add the line E:). By
default, the cd command will change the current directory for the named
drive yet not the current drive.
Assuming you have the following file structure (and if I didn't
misunderstand your description):
rootPath/
+-- ConfigFile.ini
+-- distFolder/
+-- YourApp.jar
You should set task parameters like this:
Action: Start a program
Program/script: "C:Program Files (x86)Javajre7injavaw.exe"
Add arguments (optional): -jar "rootPathdistFolderYourApp.jar"
Start in (optional): rootPath
By this way, Windows scheduler should init your java application in
rootPath directory and it shouldn't have problems to load ConfigFile.ini
Note: C:Program Files (x86)Javajre7injavaw.exe is my java path, just use
yours of course. Also note is necessary use javaw.exe. Finally at Start in
section, rootPath doesn't be quoted.")
you could write the return to a text file then the next day the program
reads the text file and starts with the number it reads from the text file
then re-writes the new value to the text file
this way you can save data while the program isnt running and retreive it
later
Hope that help :)
Obviously this comment was the answer:
use the full path of myJar.jar instead of a relative path - the running
directory of the windows scheduler is C:WindowsSystem32 and your jar-file
is probably not in this directory.
So, what's the problem? After downloading you can check the Demo.cs, where
you can find the method private void CreateSchedulerItem() and the event
triggerItem_OnTrigger. You can change this event to run the batch file that
you need.
You can create a VBS file like below
Dim iex
Set iex = CreateObject("internetexplorer.app location")
iex.Navigate ""
ie.Visible=True
Then schedule the file for execution or use this
Very interesting. Try moving file to itself by "cmd /c move file.txt
file.txt". You are correct that opening file in notepad would need you to
save it. however I would like to say no file, even if some changes being
made to it, need to be saved. In my understanding if any application that
is making change to the file is actually writing to it permanently.
Why not just call ScheduledExecutorService.scheduleAtFixedRate or
ScheduledExecutorService.scheduleWithFixedDelay?
UPDATE
This is one means of implementing what (I believe) you want:
ScheduledExecutorService executor =
Executors.newSingleThreadScheduledExecutor();
void start(final Connection conn)
{
executor.scheduleWithFixedDelay(new Runnable(){ public void run(){ try {
poll(conn); } catch (Exception e) { e.printStackTrace(); } } }, 0, 1,
TimeUnit.HOURS);
}
private void poll(Connection conn) throws SQLException
{
final ResultSet results = conn.createStatement().executeQuery("SELECT
song, playtime FROM schedule WHERE playtime > GETDATE() AND playtime
< GETDATE() + 1 HOUR");
while (results.next())
{
final String song = results.getString("song");
final Time time =
Do I need to spawn the schedules off on a new thread?
No, rufus-scheduler does it for you.
Do I need to create a new scheduler instance for each schedule I'm going
to create?
No, not at all.
Have you tried without setting a frequency (using rufus-scheduler's default
frequency)?
Although you are not hitting a rufus-scheduler issue, please read:
You are not giving any detail about your environment, it's very hard to
help you.
Try to iterate from small to big. Have a small schedule thinggy work and
then proceed one step after the other.
My workaround is to call a .BAT file from the Task Scheduler.
This batch file then calls the PowerShell script file:
powershell c:dir1AutoPopulate.ps1
Seems to work.
open('xyz') does not search the various python import paths. If you give a
relative path name, it starts with the current working directory, appends
your path and looks there. If you give an absolute path, it ignores the
current directory.
It's hard to say what is slowing down your app from the information given.
As LearnCocos2D suggested, you can use Instruments to figure out where the
slow stuff is. Or if you want to get very granular analysis, you can
always use the following macros in your code:
#define TIC start = [NSDate date]
#define TOC -[start timeIntervalSinceNow]
#define TOCP NSLog(@"TIME: %f", TOC)
Before using, be sure to declare NSDate *start in scope of use. Then just
put a series of TIC/TOC or TIC/TOCP pairs in your code to print out times
your code is taking in different places. You can very quickly find the
bottlenecks this way.
Try looking at solr-data-import-scheduler. Although I haven't used it
personally, I know of people who have done, and they seem to be happy with
it.
If using servlets, and want to run your job on application startup, I guess
this is how you should proceed to achieve.
The Job Class
public class DummyJob{
public DummyJob() throws ParseException, SchedulerException {
JobDetail job = new JobDetail();
job.setName("dummyJ");
job.setJobClass(NotificationCreater.class);
SimpleTrigger trigger = new SimpleTrigger();
trigger.setName("mn");
trigger.setStartTime(new Date(System.currentTimeMillis() + 1000));
trigger.setRepeatCount(SimpleTrigger.REPEAT_INDEFINITELY);
trigger.setRepeatInterval(30000);
Scheduler scheduler = new StdSchedulerFactory().getScheduler();
scheduler.start();
scheduler.scheduleJob(job, trigger);
}
}
The servlet
public class JobInitializerServlet extends HttpServlet {
/**
*
*/
private static final long serialVersio
The Insert Should be Performed after select, then you will be able to
insert the updated value.
Currently you are getting the value from database add 5 to it and then
leave. and insert has already been done for 1 in the start of the script
By default, the operators pick a scheduler that introduces the least
concurrency required for the operator.
If you want to know what is being used in the debugger, then put a break
point in your observer and look at the stack trace.
You should extend the class TaskScheduler in order to write your own
scheduler. Once done, you can plug it in your code via the JobTracker
property mapred.jobtracker.taskScheduler. You can find TaskScheduler inside
org.apache.hadoop.mapred.
HTH.
You have to COMMIT your DML statements. There is no COMMIT in PL/SQL block
and I guess in procedure RUNREPORT either.
You don't need an apostrophe around sysdate, it's not a string literal.
job_action => 'BEGIN RUNREPORT(''NAME'', ''VERSION'', sysdate,
''11-Jun-13''); COMMIT; END;',
BYMINUTE does not mean what you would expect. From documentation:
"This specifies the minute on which the job is to run. Valid values are 0
to 59. As an example, 45 means 45 minutes past the chosen hour". What you
need is
repeat_interval => 'FREQ=MINUTELY;INTERVAL=10'
You can check next run date and more by querying user_scheduler_jobs.
Check this post on SO. Some good options and details.
I'd recommend Quartz.NET
Okay here is what I did finally. I converted the datetime to string format
and the used it in JFS view.
DateTime dateTime = date == null ? null : new
DateTime(triggers.get(0).getNextFireTime());
if (dateTime != null) {
quartzJobList.add(new QuartzJob(jobName, jobGroup,
dateTime.toString("MM/dd/yyyy hh:mm:ss")));
}
The authors of Stackoverflow used a solution based on adding an item to the
cache, then running their scheduled code when the cache item expired and
ran a callback method.
Here is their implementation:
Edit: When it says "at startup", this means in your Global.asax file, in an
event called Application_Start.
I think you could use shutdownNow method, this should Attempts to stop all
actively executing tasks and halts the processing of waiting tasks
according to the docs.
From the man page of sched_setscheduler(), ca
The events are delivered on the specific scheduler. For example you may
want your events delivered on the threadpool rather than the UI thread. You
could use
Scheduler.Default
and then any downstream processing of your events will not impact the UI
rendering. Of course you would then need to marshal the results back to the
UI scheduler. For this switch you can use the
ObserveOnDispatcher()
method to put subsequent processing back to the UI thread.
You are setting the dataSource to use JSONP but in the action you are just
returning JSON
JSONP takes a standard JSON response and wraps in a function call. This
allows it to be loaded by adding a <script> tag into the HTML
document
JSON example { 'hello': 'world', 'num': 7 }
JSONP example callback({ 'hello': 'world', 'num': 7 });
MVC doesn't have built in support for JSONP so you can either can in (have
a look at this) or it looks like you are using it on the same domain so
plain JSON would work
I see some issues with your abstraction... It appears that you abstract
the queue, but not the Job class. This should be the opposite (or at least
your life will be a lot easier that way).
public interface IJob
{
MyJobType Type{ get; set; }
string Name { get; set; }
int Priority { get; set; }
void RunJob();
}
You can remove IQueue since you are not using it anyway.
Use only one queue unless there is a good reason not solved by #3
Abstract your job class - after all the Job that creates the cheese
sandwiches will not be the same as the one that handles meetings. With
something like the interface above you can order jobs by type (an
enumeration you create) and priority, then run them using IJob.RunJob
without having to know what they actually do in each implementation
According to the docs, sched will run all scheduled events with run(). The
text is a little obscure, but I believe that run() returns once all
scheduled events are complete. If that is the case you will need to add
more events and call run() again, and given your reported results that
seems to be what is happening.
yes there is. have a look at quartz scheduler.
its really not difficult to set-up:
// Grab the Scheduler instance from the Factory
Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
// and start it off
scheduler.start();
//);
That's a classic: (new google
groups)
(unfortunately, most of the links in those discussions are dead (4 years

You'll have to check your Passenger configuration to see how it behaves.

What about using an existing scheduling library like Quartz.net?
Quartz.NET is a full-featured, open source job scheduling system that
can be used from smallest apps to large scale enterprise systems.
Quartz.NET is a pure .NET library written in C# and is a port of very
propular open source Java job scheduling framework, Quartz . This
project owes very much to original Java project, it's father James
House and the project contributors.
REVISED
The Scheduler class has a private constructor, which means that you cannot
extend it without modifying the Guava library code.
You therefore need to take the alternative approach suggested by the
javadocs.
If more flexibility is needed then consider subclassing CustomScheduler.
(The compilation error is a bit misleading in this case ... but the bottom
line is that the extend approach will not work.)
Replace below code in onCreate() method
private Timer refresh = null;
private final long refreshDelay = 5 * 1000;
if (refresh == null) { // start the refresh timer if it is null
refresh = new Timer(false);
Date date = new Date(System.currentTimeMillis()+
refreshDelay);
refresh.schedule(new TimerTask() {
@Override
public void run() {
postHttpRequest("Test","Test");
refresh();
}
}, date, refreshDelay);
Use JobDataMap to hold your custom data and use during the executing of
job.
Ex:
JobDetail job = JobBuilder.newJob(TestJob.class)
.withIdentity("testJob")
.build();
job.getJobDataMap().put("mobile", "1234567890");
job.getJobDataMap().put("msg", "Your balance is low");
public void execute(JobExecutionContext jExeCtx) throws
JobExecutionException {
try {
JobDataMap dataMap = context.getJobDetail().getJobDataMap();
String msg = dataMap.getString("msg");
String mobile = dataMap.getFloat("mobile");
SendSms.sendSms(mobile,msg);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
log.debug("TestJob run successfully...");
}
I've added scheduling to a __init__ module in one of my project application
(in terms of Django), but wrapped with small function which prevents
queueing jobs twice or more. Scheduling strategy may be dependent of your
specific needs (i.e. you may need additional checking for a job arguments).
Code that works for me and fit my needs:
import django_rq
from collections import defaultdict
import tasks
scheduler = django_rq.get_scheduler('default')
jobs = scheduler.get_jobs()
functions = defaultdict(lambda: list())
map(lambda x: functions[x.func].append(x.meta.get('interval')), jobs)
now = datetime.datetime.now()
def schedule_once(func, interval):
"""
Schedule job once or reschedule when interval changes
"""
if not func in functions or not interval in functions[func]
Oracle Scheduler has all options where you are looking for and probably
more. See Overview of Oracle Scheduler for some global info. It comes doen
to having a central schedular database that submits jobs to remote job
agents that do the work pretty much independent from the central schedular
repository. It does report back status etc. when the repository is
accessible after a job has finished.
It's a very powerful tool and it takes away a lot of complex tasks for you
by giving a framework that you can start using right out of the box.
I do not completely understand your situation.
However I can offer a suggestion, will the following be possible:
Store those values in a new table.
Use a separate SQL query to retrieve these 2 values, which you store in
variables.
Then just set those values to point to those 2 variable.
All the above must happen on page load and before setting those 2 values.
Hope it helps.
the values in quartz_trigger i.e. the next_fire_time in table is changed
after the execution >time of the job
Yes, this is quartz actually does in case of misfires.
As per the misfire instruction provided while creating a trigger, quartz
calculates how many times the misfired execution has to be executed.
As per your code , you have set the misfire instruction as "fireAndProceed"
, So Quartz just executes the very first misfired execution ( and neglect
all the subsequent remaining misfires). Ex: If you set the trigger to fire
between 2Pm to 4pm with interval of 30 min and if scheduler was down during
2:29pm to 3.29pm, then only one trigger execution of time 2.30pm
will be executed ( and executions of 3.pm will be neglected).

Off the back of the Interface Monitoring post I had created a class that queries the Ens.AlertRequest global and returns the entries between 6pm the night before and 6am in the morning.
I tested this build in our T&D environments and the build worked very well.
However in our production environment the query is being truncated, by what I believe to be a timeout and I get a partial query output.
In the System>SQL pages my 12 hour query times out.
I compared the Global size by running a SELECT MAX(ID) query and got a return of 60,244,962 records. This may go some way to explain why the query is taking longer and possibly timing out.
In our T&D environments (which we don't purge), we have only 1 million and 2.5 million records.
For messages we in production we have a 90 day purge limit.
I wonder if the Ens.AlertRequest global isn't being purged and if so why it isn't as this global is considered to be a message in my mind.
Any advice please.
Regards
Stuart
Please find my method below which is used to drive a Business Operation. It's activated by a schedule on a daily basis at 6am:
MAX(ID) isn't necessarily the record count. Try a "select count(*) from Ens.AlertRequest" query and see what you get. Compare that to "'select count(*) from Ens.MessageHeader where MessageBodyClassName = 'Ens.AlertRequest'"
If the numbers are in line with the MAX(ID), then my suspicion is that you either don't have "BodiesToo" checked or do have "KeepIntegrity" checked in your purge process configuration. Either of those may be keeping old Ens.AlertRequest bodies around.
Hi Jeffrey,
SELECT COUNT(ID) & SELECT COUNT (*) are timing out via the System>SQL pages.
I had a look at our purge settings and we have "BodiesToo" unchecked and "KeepIntegrity" checked.
The next way forward would be to investigate the effect of purging with the "BodiesToo" and see if this reduces the EnsAlertRequest global size.
If you have access to Caché terminal, you can run run queries that won't time out:
(the sample below assumes your namespace is "PROD"; just substitute whatever your production's namespace is for that).
USER> zn "PROD"
PROD> d $system.SQL.Shell()
SQL Command Line Shell
----------------------------------------------------
The command prefix is currently set to: <<nothing>>.
Enter q to quit, ? for help.
PROD>>SELECT COUNT(*) AS AlertCount FROM Ens.MessageHeader WHERE MessageBodyClassName = 'Ens.AlertRequest'
AlertCount
2205
PROD>>Q
PROD>
So ... if you don't have BodiesToo checked, you most likely have lots of orphaned message bodies taking up database space. And KeepIntegrity is probably retaining a lot of message headers (and associated bodies) that you don't care about anymore. There are reasons you would not want to turn KeepIntegrity off in earlier versions of Caché/Ensemble, like pre-2015 releases. If you're on a release more modern than that and you don't need to worry about messages with parent/child relationships (certain batch types, for example), you can probably turn that off.
There are a couple of articles regarding the management of orphaned bodies here on DC. Might be worthwhile to peruse them :)
Thanks Jeffrey.
I've spoken to our Caché ODBA and he concurs there are orphaned records in the Ens.Message* globals.
We're on 2017.1 currently, but have been live since Caché 2012, which may explain todays issues.
Looking at the purge tasks we have records with no timestamp, which would escape the purging process.
Our Caché ODBA is going to open a WRC to confirm the best course of action for a one off purge of these Ens.Message* globals.
Thank you so much for your advice as it has helped immensely identifying this issue.

Update: thanks to Bill for catching that VB doesn't show snippet shortcuts in the statement completion. I've updated the VB picture below to better illustrate what is going on. Also, check out Bill's post, as he talks about using the '?' to insert snippets.
This is probably a much better tip than the previous two. Code Snippets have the support to be given a "shortcut", usually an abbreviated version of the code snippet name that you can type into the editor and hit tab to insert.
To insert, simply type in the name of the snippet, e.g. "for", then hit tab. Note that if statement completion is open, you'll have to hit tab twice to insert the snippet.
In both Visual Studio 2005 and 2008, you will be able to see C# Code Snippet shortcuts in the Statement Completion window. Below is the for snippet displayed within the Statement Completion window. Note the snippet icon to the left.
In Visual Studio 2008, you won't see VB snippets in the statement completion window, but you will see a note in the tooltip when you can hit tab twice to insert the corresponding snippet.
VB does NOT display snippets in the statement completion window, it only displays namespaces, types, members and Keywords.
Also note that with VB you cannot insert a snippet by typing it's name and hitting tab if the shortcut is a substring of anything that displays in the completion window. (you could in 2005, but this was broken intentionally for 2008)
Sara Ford writes about inserting snippets in VB and C#. Unfortunately, Sara has got it quite right. In

We are moving our product’s OS from RedHat 5 to 6, as well as new version of ‘gcc’ (4.X) along with RH6. To port the existing code to RH6 with new compiler, there might be a lot of things we need to care. This post gives a brief summary for the issue during our trial and hopefully would be updated timely. May it help:)
1. C++ header file include
#include <iostream.h> -> #include <iostream>
#include <typeinfo.h> -> #include <typeinfo>
#include <list.h> -> #include <list>
#include “poll.h” -> #include <poll.h>
#include “fcntl.h” -> #include <fcntl.h>
a. All the standard C++ header file need to omit “.h”;
b. Standard C header file could have both format:
#include <stdio.h> OR
#include <cstdio>
NOT #include “stdio.h”
2. SCTP library
libsctp.a -> -lsctp
RH 6 does not support static lib of SCTP. Should be dynamically linked.
3. SCTP struct/API
sctp_adaption_layer_event -> sctp_adaptation_layer_event
SCTP_ADAPTION_INDICATION -> SCTP_ADAPTATION_INDICATION
sctp_connectx(int, sockaddr*, int) -> sctp_connectx(int, sockaddr*, int, sctp_assoc_t*)
a. Member name updated in structure sctp_event_subscribe
b. Member name updated in enum sctp_sn_type
c. New argument updated in function sctp_connectx
4. Linux Kernel API

Red Hat Bugzilla – Bug 244695
syntax error in include/asm/page.h?
Last modified: 2007-11-30 17:12:07 EST
Trying to compile the VMware modules with 2.6.21-1.3223.fc8, I get:
include/asm/page.h: In function 'pte_t native_make_pte(long unsigned int)':
include/asm/page.h:112: error: expected primary-expression before ')' token
include/asm/page.h:112: error: expected ';' before '{' token
include/asm/page.h:112: error: expected primary-expression before '.' token
include/asm/page.h:112: error: expected `;' before '}' token
Note that this particular file is being compiled in C++ mode, not C mode. The
function in question is:
static inline pte_t native_make_pte(unsigned long val)
{
return (pte_t) { .pte_low = val };
}
I made the problem go away by changing it to this:
static inline pte_t native_make_pte(unsigned long val)
{
pte_t ret;
ret.pte_low = val;
return ret;
/* return (pte_t) { .pte_low = val }; */
}
I can't claim to understand the niceties of C++ syntax enough to understand why
the C++ compiler didn't like the previous syntax, nor do I know whether this is
a problem with the header file or a problem with g++ (gcc-c++-4.1.2-13 is what
I've got), so I'm making a best guess and filing under kernel. Please reassign
if appropriate.
*** Bug 244696 has been marked as a duplicate of this bug. ***
This is a vmware problem, they need to change their code.
Kernel headers have never supported c++ compilation, and never will AFAICT. | https://bugzilla.redhat.com/show_bug.cgi?id=244695 | CC-MAIN-2017-04 | refinedweb | 247 | 59.5 |

Short of a new network protocol you might have issues getting the IP blocks for international routing. The only way I can see it happening is during the migration to IPv6 and only if either the world unanimously votes to start their own equivalent of IANA allows current non-US blocks to remain allocated without paying a second time (perhaps simply paying their next renewal fee to the Internationalized replacement to 'port over') and formally choosing to disconnect from the US portion of the internet in order to avoid any segmentation caused by US routing tables disagreeing on IPv6 address ownership.
Personally however I think skipping over IPv6 and adding some 'forwards compatible' region address blocks to the protocol to better handle future networking needs (notably for offering an easier way to avoid 'namespace pollution' by seperating the networks into regions based off a numerical 'country id', and perhaps eventually even a 'celestial body' id would go a long ways towards avoiding another IPv4 style migration when we begin approaching the new networks limitations in what will probably turn out to be the forseeable future.)

The problem with the US is not just the resources, it's the pussy-ass attitude of spending all of those resources internationally on humanitarian and police actions. Those are freaking EXPENSIVE. Bombing the shit out of any piss-ant country who challenged the US would have been much cheaper.
Take away 100% of US humanitarian aid to foreign countries and 100% US military expenditure on defense or police action on foreign issues and that would save about a half a trillion dollars a year. And what would be lost? I don't know, every other country in the world manages to survive without spending a trillion dollars on foreign policy.

In the short term the Chinese have banned the purchase of American networking hardware, and instead requires people to buy Chinese or if that's not available to buy European.

Tricks will only work once against China, after that they start working on a solution to prevent it ever happening again. It may take them years but expect that to occur with the internet too.

An epic nation building boondoggle for domestic hardware supplies, skilled coders, telcos, engineers and private security firms.
The most important aspect the US seemed to have wanted to shape was standards of crypto, OS and database backends per nation. To be decoded and readable from the USA as needed with limited US or local staff 'knowing'.
So you need your own file system, own OS, own database, own crypto and understanding that all wider national and international networks are a constant threat.

No escape ?
Your perspective is rather limited, as, it seems, your imagination also is.
People thought there was "no escape" from the Nazis too,
and look what happened to them. When enough people
get fed up, all manner of change can happen.

Anonymous Coward | about a year ago | (#44956539)
This isn't really a technical issue. Of course a non-US "Internet" can exist - at heart the internet is just a huge network of computers.
The real issue is content. What exactly would a Brazilian internet offer that would interest people in Sweden, the UK or Japan? Or for that matter, people in Brazil?
The US isn't just the predominant force on the internet for technical reasons, although they certainly help. The US probably have the world's largest group of creative people, and the websites and services they create are in English, the only real international language right now.
Big business has such a grip on popular web sites and services that it's easy to forget that many of the most popular sites today were started by a handful of people who had a good idea - like Google, Facebook and Yahoo.
Without good content and services, a non-US internet wouldn't get any visitors - it would be greatly reduced in value from what we have today. It's not impossible - the ability of other countries to ignore US software patents would be extremely useful - but it would take a number of years for the alternative internet to reach the level of usefulness that we have today. Is there enough incentive for companies and people to rebuild the internet from scratch?

The onslaught of marketing from the (currently) big sites in the US has actually helped to kill off quite a few sites in other countries. Many of those sites offered the same thing as the big US sites, and predated them by a few years, but were mostly limited to the local spoken language.
As for the "US probably have the world's largest group of creative people", I'd like some of what you're smoking.

The problem is that this kind of "news" is the same kind of bs propaganda Americans have to deal with everyday. Brazil is definitely not trying to block US services or itself from the rest of the world. It's mostly trying to use the human and national rights card to bring servers, services and infrastructure to the country. And doing so by protecting it's citizens rights and holding the companies accountable, at the same time that they protect national resources.
Google and Facebook won't quit a free country with 200 million people just because they will have to spend some money abroad. Specially if you consider that Brazil is in the top countries for their services.
On a different subject, some of the things that are not being discussed in US or in the English speaking internet and actually matters (is true) is how US companies did strategic planning for previous governments (before Lula) that included privatizing communications, oil, energy, etc and having an actual american spy center in Brasília. Our previous governments were part of the American system, all that is coming out and Brazil has been asking for full disclosure so that we can know who is working for whom.
I do agree with you, ignoring patents would bring huge advancements all around the world, and even more in US if they were willing to do the same with their own patents (cause they already do with others patents).

Table of Contents
What is Bypass?
Bypass is described as “a quick way to create a custom plug that can be put in place instead of an actual HTTP server to return prebaked responses to client requests.”
What does that mean? Under-the-hood Bypass is an OTP application that masquerades as an external server listening for and responding to requests. By responding with pre-defined responses we can test any number of possibilities like unexpected service outages and errors along with the expected scenarios we’ll encounter, all without making a single external request.
Using Bypass
To better illustrate the features of Bypass we’ll be building a simple utility application to ping a list of domains and ensure they’re online. To do this we’ll create new supervisor project and a GenServer to check the domains on a configurable interval. By leveraging Bypass in our tests we’ll be able to verify our application will work in many different outcomes.
Note: If you wish to skip ahead to the final code, head over to the Elixir School repo Clinic and have a look.
By this point we should be comfortable creating new Mix projects and adding our dependencies so we’ll focus instead of the pieces of code we’ll be testing. If you do need a quick refresher, refer to the New Projects section of our Mix lesson.
Let’s start by creating a new module that will handle making the requests to our domains.
With HTTPoison let’s create a function,
ping/1, that takes a URL and returns
{:ok, body} for HTTP 200 requests and
{:error, reason} for all others:
defmodule Clinic.HealthCheck do def ping(urls) when is_list(urls), do: Enum.map(urls, &ping/1) def ping(url) do url |> HTTPoison.get() |> response() end defp response({:ok, %{status_code: 200, body: body}}), do: {:ok, body} defp response({:ok, %{status_code: status_code}}), do: {:error, "HTTP Status #{status_code}"} defp response({:error, %{reason: reason}}), do: {:error, reason} end
You’ll notice we are not making a GenServer and that’s for good reason: By separating our functionality (and concerns) from the GenServer, we are able to test our code without the added hurdle of concurrency.
With our code in place we need to start on our tests.
Before we can use Bypass we’ll need to ensure it’s running.
To do that, let’s update
test/test_helper.exs look like this:
ExUnit.start() Application.ensure_all_started(:bypass)
Now that we know Bypass will be running during our tests let’s head over to
test/clinic/health_check_test.exs and finish our setup.
To prepare Bypass for accepting requests we need to open the connect with
Bypass.open/1, which can be done in our test setup callback:
defmodule Clinic.HealthCheckTests do use ExUnit.Case setup do bypass = Bypass.open() {:ok, bypass: bypass} end end
For now we’ll rely on Bypass using it’s default port but if we needed to change it (which we’ll be doing in a later section), we can supply
Bypass.open/1 with the
:port option and a value like
Bypass.open(port: 1337).
Now we’re ready to put Bypass to work.
We’ll start with a successful request first:
defmodule Clinic.HealthCheckTests do use ExUnit.Case alias Clinic.HealthCheck setup do bypass = Bypass.open() {:ok, bypass: bypass} end test "request with HTTP 200 response", %{bypass: bypass} do Bypass.expect(bypass, fn conn -> Plug.Conn.resp(conn, 200, "pong") end) assert {:ok, "pong"} = HealthCheck.ping("{bypass.port}") end end
Our test is simple enough and if we run it we’ll see it passes but let’s dig in and see what each portion is doing.
The first thing we see in our test is the
Bypass.expect/2 function:
Bypass.expect(bypass, fn conn -> Plug.Conn.resp(conn, 200, "pong") end)
Bypass.expect/2 takes our Bypass connection and a single arity function which is expected to modify a connection and return it, this is also an opportunity to make assertions on the request to verify it’s as we expect.
Let’s update our test url to include
/ping and assert both the request path and HTTP method:
test "request with HTTP 200 response", %{bypass: bypass} do Bypass.expect(bypass, fn conn -> assert "GET" == conn.method assert "/ping" == conn.request_path Plug.Conn.resp(conn, 200, "pong") end) assert {:ok, "pong"} = HealthCheck.ping("{bypass.port}/ping") end
The last part of our test we use
HealthCheck.ping/1 and assert the response is as expected, but what’s
bypass.port all about?
Bypass is actually listening to a local port and intercepting those requests, we’re using
bypass.port to retrieve the default port since we didn’t provide one in
Bypass.open/1.
Next up is adding test cases for errors.
We can start with a test much like our first with some minor changes: returning 500 as the status code and assert the
{:error, reason} tuple is returned:
test "request with HTTP 500 response", %{bypass: bypass} do Bypass.expect(bypass, fn conn -> Plug.Conn.resp(conn, 500, "Server Error") end) assert {:error, "HTTP Status 500"} = HealthCheck.ping("{bypass.port}") end
There’s nothing special to this test case so let’s move on to the next: unexpected server outages.
Τhese are the requests we’re most concerned with.
To accomplish this we won’t be using
Bypass.expect/2, instead we’re going to rely on
Bypass.down/1 to shut down the connection:
test "request with unexpected outage", %{bypass: bypass} do Bypass.down(bypass) assert {:error, :econnrefused} = HealthCheck.ping("{bypass.port}") end
If we run our new tests we’ll see everything passes as expected!
With our
HealthCheck module tested we can move on to testing it together with our GenServer based-scheduler.
Multiple external hosts
For our project we’ll keep the scheduler barebones and rely on
Process.send_after/3 to power our reoccuring checks, for more on the
Process module take a look at the documentation.
Our scheduler requires three options: the collection of sites, the interval of our checks, and the module that implements
ping/1.
By passing in our module we further decouple our functionality and our GenServer, enabling us to better test each in isolation:
def init(opts) do sites = Keyword.fetch!(opts, :sites) interval = Keyword.fetch!(opts, :interval) health_check = Keyword.get(opts, :health_check, HealthCheck) Process.send_after(self(), :check, interval) {:ok, {health_check, sites}} end
Now we need to define the
handle_info/2 function for the
:check message sent
send_after/2.
To keep things simple we’ll pass our sites to
HealthCheck.ping/1 and log our results to either
Logger.info or in the case of errors
Logger.error.
We’ll setup our code in a way that will enable us to improve the reporting capabilities at a later time:
def handle_info(:check, {health_check, sites}) do sites |> health_check.ping() |> Enum.each(&report/1) {:noreply, {health_check, sites}} end defp report({:ok, body}), do: Logger.info(body) defp report({:error, reason}) do reason |> to_string() |> Logger.error() end
As discussed we pass our sites to
HealthCheck.ping/1 then iterate the results with
Enum.each/2 applying our
report/1 function against each.
With these functions in place our scheduler is done and we can focus on testing it.
We won’t focus too much on unit testing the schedulers since that won’t require Bypass, so we can skip to the final code:
defmodule Clinic.SchedulerTest do use ExUnit.Case import ExUnit.CaptureLog alias Clinic.Scheduler defmodule TestCheck do def ping(_sites), do: [{:ok, "pong"}, {:error, "HTTP Status 404"}] end test "health checks are run and results logged" do opts = [health_check: TestCheck, interval: 1, sites: ["", ""]] output = capture_log(fn -> {:ok, _pid} = GenServer.start_link(Scheduler, opts) :timer.sleep(10) end) assert output =~ "pong" assert output =~ "HTTP Status 404" end end
We rely on a test implementation of our health checks with
TestCheck alongside
CaptureLog.capture_log/1 to assert that the appropriate messages are logged.
Now we have working
Scheduler and
HealthCheck modules, let’s write an integration test to verify everything works together.
We’ll need Bypass for this test and we’ll have to handle multiple Bypass requests per test, let’s see how we do that.
Remember the
bypass.port from earlier? When we need to mimic multiple sites, the
:port option comes in handy.
As you’ve probably guessed, we can create multiple Bypass connections each with a different port, these would simulate independent sites.
We’ll start by reviewing our updated
test/clinic_test.exs file:
defmodule ClinicTest do use ExUnit.Case import ExUnit.CaptureLog alias Clinic.Scheduler test "sites are checked and results logged" do bypass_one = Bypass.open(port: 1234) bypass_two = Bypass.open(port: 1337) Bypass.expect(bypass_one, fn conn -> Plug.Conn.resp(conn, 500, "Server Error") end) Bypass.expect(bypass_two, fn conn -> Plug.Conn.resp(conn, 200, "pong") end) opts = [interval: 1, sites: ["", ""]] output = capture_log(fn -> {:ok, _pid} = GenServer.start_link(Scheduler, opts) :timer.sleep(10) end) assert output =~ "[info] pong" assert output =~ "[error] HTTP Status 500" end end
There shouldn’t be anything too surprisingly in the above test.
Instead of creating a single Bypass connection in
setup, we’re creating two within our test and specifying their ports as 1234 and 1337.
Next we see our
Bypass.expect/2 calls and finally the same code we have in
SchedulerTest to start the scheduler and assert we log the appropriate messages.
That’s it! We’ve built a utility to keep us informed if there’s any issues with our domains and we’ve learned how to employe Bypass to write better tests with external services.

Hi,
First of all, it is not required to extend the class to have attributes, but if you need a subclass for some other reason, then there is a way to solve this.
Simply make your class A behave as a Club class in the eyes of the framework. Meaning you will have to put attributes on the Club class for them to be available for class A. This will make ClubQuery work also.
There is a .Net attribute you will have to add to class A, with the name EntityTypeOverrideAttribute, like this:
[StarCommunity.Core.Modules.EntityTypeOverride(typeof(Club))] public class A : Club { }
Great! Didn't know about the EntityTypeOverride, it solved everything (altough I had to transfer data from attribut of class A to matching Club attribute).
The reason to extend Club was simply to handle attributes without having to know the attribute name all over the site, like a.Location instead of club.getAttributeValue<string>("attr_location")...
Anyway, thanks a lot - it saved my day :)
Is there any way to query custom attributes in an extended class?
I have extended the Club module to a new class A, with some extra attributes. When searching for A I use ClubQuery and gets the expected result - as long as I create queries with only Club attributes (Name, Description, etc.). BUT I now want to create a query with a custom attribute that only exists in the extension (A). Of course the following error occurs: "There is no attribute with the name 'attr_location' for the type 'StarCommunity.Modules.Club.Club'." Any ideas how to solve this?
Should I somehow create a custom AQuery, extending ClubQuery? How could I then force it to query type A? Or should I add the attribute to Club and somehow get/set custom attribute in base class of A? | https://world.optimizely.com/forum/legacy-forums/Episerver-Community/Thread-Container/2008/9/attribute-query/ | CC-MAIN-2021-39 | refinedweb | 302 | 72.97 |
Issue importing multiple tasks to Appigo ToDo
Hello,
I'm new to Python so apologies in advance for a newbie question. I would like to create a pythonista program that can copy a list of tasks from my clipboard and pass them to either Appigo ToDo or Reminders.
The clipboard data may contain:
Buy lettuce
Buy laundry detergent
Buy tomatoes
The code below appears to function for only the first task in the list stored in the clipboard.
Does anyone know how I can modify this to work with Appigo Todo? Alternatively, does anyone know if there is a URL scheme to access Reminders?
Thanks in advance!
-jtg
---code below---
<pre>import clipboard
import urllib
import webbrowser
todo = 'appigotodo://x-callback-url/import?name='
text = clipboard.get()
tasks = text.split('\n')
for index in range(len(tasks)):
task = urllib.quote(tasks[index])
webbrowser.open(todo + task)</pre>
I'm not really familiar with Appigo Todo, so I'm not sure if their URL scheme supports adding multiple todos in one go. What happens in your script is that as soon as you open the first URL, Pythonista exits and Appigo Todo is opened, so the script doesn't continue. That is in general how URL schemes work, you would have to find a way (if possible) to add multiple tasks in <em>one</em> URL.
There is no URL scheme for Apple's built-in reminders app.
Btw, there's no need to use the index in your for-loop, just write:
<pre>for task in tasks:
...</pre>
Thank you for the quick response OMZ! This makes sense. I think I'll inquire with Appigo regarding whether it's possible to add multiple tasks in one URL.
Thanks,
jtg
Just realized that I had bought Appigo Todo at some point, so I've experimented a little, but it doesn't seem to be possible to add multiple tasks by opening one URL...
OMZ - thanks for trying to look into this further!
Viticci - thank you for sending that. It's a similar use case and might be worth checking out Due if it supports sequential tasks. Thanks!
- Denrael245
Just curious; my understanding is that Reminders is at it's core iCal style calendars.

XOR turns out to be a bad argument.
In this document I will illustrate that how a logistic regression can hold up against a support vector machine in a situation where you would expect a support vector machine to perform better. Typically logistic regression fails due to the XOR phenomenon that can occur in data, but there is a trick around it.
The goal of this document is to convince you that you may need to worry more about the features that go into a model, less about which model to pick and how to tune it.
For this experiment I will use python and I’ll assume that the following libraries are loaded:
import numpy as np import pandas as pd import patsy from ggplot import * from sklearn.linear_model import LogisticRegression from sklearn.svm import SVC from sklearn.metrics import confusion_matrix
da = np.random.multivariate_normal([1,1], [[1, 0.7],[0.7, 1]], 300) dfa = pd.DataFrame({'x1':da[:,0], 'x2': da[:,1], 'type' : 1}) db1 = np.random.multivariate_normal([3,0], [[0.2, 0],[0, 0.2]], 150) dfb1 = pd.DataFrame({'x1':db1[:,0], 'x2': db1[:,1], 'type' : 0}) db2 = np.random.multivariate_normal([0,3], [[0.2, 0],[0, 0.2]], 150) dfb2 = pd.DataFrame({'x1':db2[:,0], 'x2': db2[:,1], 'type' : 0}) df = pd.concat([dfa, dfb1, dfb2]) (ggplot(aes(x='x1', y='x2', color="type"), data=df) + geom_point() + ggtitle("sampled data"))
This should show a dataset similar to this one:
We’ve generated a classification problem that is impossible to split linearly. Typically we would expect the (linear) logistic regression to perform poorly here and we would expect a (non-linear) support vector machine to perform well.
y,X = patsy.dmatrices("type ~ x1 + x2", df)
Let’s see how both models perform now.
> pred = LogisticRegression().fit(X,ravel(y)).predict(X) > confusion_matrix(y,pred) array([[223, 77], [118, 182]])
> pred = SVC().fit(X,ravel(y)).predict(X) > confusion_matrix(y, pred) array([[294, 6], [ 2, 298]])
The SVM performs much better than the LR. How might we help this?
Let’s see if we can help the logistic regression out a bit. Maybe if we combine
x1 and
x2 into something nonlinear we may be able capture the problem in this particular dataset better.
> df['x1x2'] = df['x1'] * df['x2'] > y,X = patsy.dmatrices("type ~ x1 + x2 + x1x2", df) > pred = LogisticRegression().fit(X,ravel(y)).predict(X) > confusion_matrix(y,pred) array([[290, 10], [ 3, 297]])
I am feeding different data to the logistic regression, but by combining x1 and x2 we have suddenly been able to get a non-linear classification out of a linear model. I am still using the same dataset however, which goes to show that being creative with your data features can have more of an effect than you might expect.
Notice that the support vector machine doesn’t show considerable improvement when applying the same trick.
> pred = SVC().fit(X,ravel(y)).predict(X) > confusion_matrix(y, pred) > array([[294, 6], [ 2, 298]])
Why is this trick so useful?
You can apply more statistical theory to the regression model which is something a lot of clients (especially those who believe in econometrics) find very comforting. It is less a black box and feels like you might be better prepared for when something goes wrong.

Login.aspx File
Logon.aspx is the file to which the request is redirected if ASP.NET does not find a cookie with the request. This URL was set up in the configuration file. In the following example, a form containing two text boxes (labeled E-mail Name and Password) and a Submit button is presented to the client user. The user enters the e-mail name and password, and clicks the Submit button. The code then looks for this name and password combination in an XML file located in this directory. If it is in the file, the user is connected to Default.aspx. If it is not, the AddUser.aspx file is called.
To create a file to log on a user
- Import the necessary namespaces.
- Create a script section for the code.
- Implement a Logon_Click function.
- If the page is not valid, tell the user.
Set up a string named
cmdthat is initialized to UserEmail="MyName", where MyName is the user's e-mail name. The regular expression validator control attached to the input control has already determined that the e-mail name is formatted properly and does not contain invalid characters.
- Create a new instance of the DataSet class.
- Read in the XML file containing authenticated user name and password combinations. The retrieved data resides in
ds, the DataSet created in the previous step.CAUTION For the sake of simplicity and the clarity of the example, the following code does not follow best design practices for security. It does not invoke any file-locking or file-sharing flags. Also, in a commercial Web site, you should use a relational database or other secure and scalable mechanism to store the list of authenticated users.
- Create a new instance of a DataTable named
usersthat is initialized to
ds.
- Check for any matches between the logon name and the list of names in Users.aspx. For each match found, record the name in a DataRow named
matches.Note For the sake of simplicity, this example expects each name to be unique; therefore, only the first match found is used.
- Check each of the name matches found in the previous step to see whether there is a matching password for any of them.
- If a user name match is found, hash the user's password and compare it to the hash stored in the Users.xml file.
DataRow row = matches[0]; string hashedpwd = FormsAuthentication.HashPasswordForStoringInConfigFile (UserPass.Value, "SHA1"); String pass = (String)row["UserPassword"]; if( 0 != String.Compare(pass, hashedpwd, false) ) // Tell the user if no password match is found. It is good // security practice give no hints about what parts of the // logon credentials are invalid. Msg.Text = "Invalid Credentials: Please try again."; else // If a password match is found, redirect the request // to the originally requested resource (Default.aspx). FormsAuthentication.RedirectFromLoginPage (UserEmail.Value, Persist.Checked); } else { // If no name matches were found, redirect the request to the // AddUser page using a Response.Redirect command. Response.Redirect("AddUser/AddUser.aspx"); } } </script> <body>
- Display a form to collect the logon information.
- Create a User E-mail Name text box. Add a RequiredFieldValidator control and a RegularExpressionValidator control that check for a valid e-mail name entry. The RegularExpressionValidator verifies that the e-mail address is in valid e-mail format (for example, name@contoso.com) and does not contain invalid characters that could compromise security.
<td>e-mail:<>
- Create a Password text box.
- Create a Persistent Cookie check box. If the Persistent Cookie box is selected, the cookie is valid across browser sessions. Otherwise, when the browser is closed, the cookie is destroyed. Issuing persistent cookies might be desirable for some sites for reasons of convenience, but it is offers less protection than issuing short-lived cookies.
- Create a Submit button that causes the Logon_Click event to be raised on postback.

QWizardPage Class Reference
The QWizardPage class is the base class for wizard pages. More...
#include <QWizardPage>
This class was introduced in Qt 4.3.
Properties
Public Functions
- 221 public functions inherited from QWidget
- 29 public functions inherited from QObject
- 13 public functions inherited from QPaintDevice
Signals:
- initializePage() is called to initialize the page's contents when the user clicks the wizard's Next button. If you want to derive the page's default from what the user entered on previous pages, this is the function to reimplement.
- cleanupPage() is called to reset the page's contents when the user clicks the wizard's Back button.
- validatePage() validates the page when the user clicks Next or Finish. It is often used to show an error message if the user has entered incomplete or invalid information.
- nextId() returns the ID of the next page. It is useful when creating non-linear wizards, which allow different traversal paths based on the information provided by the user.
- isComplete() is called to determine whether the Next and/or Finish button should be enabled or disabled. If you reimplement isComplete(), also make sure that completeChanged() is emitted whenever the complete state changes..

Summary: Guest blogger, Trevor Sullivan, talks about invoking CIM methods via Windows PowerShell.
Microsoft Scripting Guy, Ed Wilson, is here. Today we have another guest post from Trevor Sullivan. Trevor is an Honorary Scripting Guy, and a recognized Microsoft Community Contributor (MCC). To see more of Trevor’s guest posts, see these Hey, Scripting Guy! Blog posts.
Note This is the fourth in a series of five posts by Trevor where he talks specifically about using the CIM cmdlets. To catch up, read the following posts:
Here’s Trevor…
In yesterday’s post, we talked about reading and writing CIM properties. Today, we’ll look at WMI/CIM methods.
In the context of programming terminology, methods generally represent actions that you can perform against an object. In CIM/WMI, this is no exception. Similar to properties, methods can be declared as static or instance methods. Static methods are declared on a class, and generally don’t operate on any particular instance of that class. Instance methods are generally actions that are performed against a specific instance of the class.
Classes are blueprints of an object that do not represent an instance of the object itself. For example, think of a car blueprint. The blueprint represents what a car might look like, how many wheels it has, how many doors it has, the size of the engine, what type of transmission it has, and so on. Blueprints are not actual cars, however. Therefore, a static method might be defined at the class (blueprint) level called Build(), which produces a car.
Instance methods generally operate on an instance of the class that declares the method. To get an instance of a car, you must first call the blueprint’s Build() method. When you have a specific car (instance) that is built according to the blueprint’s (class) specifications, you could begin calling instance-level methods on it.
On any given car instance, you might have a method called Drive(), which causes the car to move. Similarly, you might have an OpenHood() method, which opens the hood of the vehicle. Because these methods operate on a specific car, they are better declared at the instance (specific car) level as opposed to the class (blueprint) level.
Moving from the car example to a software example, you could have a class called Process. This class does not represent a specific process (such as svchost.exe or iexplore.exe), but rather, it defines a blueprint for what a process looks like.
In CIM/WMI, there is in fact a class called Win32_Process that exists in the root\cimv2 WMI namespace. This class has a static (blueprint) method called Create(), which allows you to create (start) a process in a Windows operating system. After you have a process, you have the ability to terminate the process using the Terminate() method. The Terminate() method is an instance-level method because the action of terminating is performed against a specific process.
Here is some sample script that shows how to call the Win32_Process.Terminate() CIM method by using the new Invoke-CimMethod cmdlet. This method call is particularly easy because we do not have to specify any method parameters.
# Start a new instance of notepad.exe
notepad;
# Retrieve the Win32_Process instance for notepad.exe
$Notepad = Get-CimInstance -ClassName Win32_Process -Filter "Name = 'notepad.exe'";
# Invoke the Win32_Process.Terminate() method
Invoke-CimMethod -InputObject $Notepad -MethodName Terminate;
Static methods can be called easily also. Let’s take a look at the Win32_Process.Create() method, which creates a new process. The Create() method is different from Terminate() because it requires that we pass method parameters to it, specifically the path to the process that we want to start. How do we know what those parameters are?
Let’s first look at a list of CIM methods that are available for the Win32_Process class:
(Get-CimClass -ClassName Win32_Process).CimClassMethods;
Then, let’s narrow things down specifically to the Create() method:
(Get-CimClass -ClassName Win32_Process).CimClassMethods['Create'].Parameters;
Now we can see a list of all the method parameters that Create() requires:
To use Invoke-CimMethod to call the Create() method, we need to create a HashTable of parameters to pass into it.
$Arguments = @{
CommandLine = 'notepad.exe';
CurrentDirectory = $null;
ProcessStartupInformation = $null;
};
Then, we can call the method.
Invoke-CimMethod -ClassName Win32_Process -MethodName Create -Arguments $Arguments;
When you run the previous script on a local computer, you should see notepad.exe running. You might wonder why we left out the ProcessId parameter when we started the process. The reason is that the process ID is an “out” parameter, which is returned to us when the process is launched. We do not need to pass a ProcessId into the Create() method, because that simply doesn’t make sense.
A couple of days ago, I briefly mentioned how WMI methods are not bound to the .NET objects, when you use the CIMCmdlets PowerShell module. Let’s take a look at how things have changed from the traditional WMI days.
One relatively common task that is performed through WMI is terminating processes, which we explored earlier in this post. If you want to terminate a process by using WMI, you could simply call the appropriate WMI method on the WMI object that you received from the Get-WmiObject cmdlet:
(Get-WmiObject -Class Win32_Process -Filter "Name = 'notepad.exe'").Terminate();
If you want to call a static method on a class, such as the Create() method on the Win32_Process class, you could use the [wmiclass] type accelerator to get a reference to the class, and then call the static method by using the dot/period operator:
([wmiclass]"root\cimv2:Win32_Process").Create('notepad.exe');
If you called the method without any parameters and sans the parentheses, Windows PowerShell used to show you the WMI method signature. Unfortunately, you now have to use a bit more effort to figure out the method signature by using an external GUI tool, or by using the Get-CimClass cmdlet, as previously demonstrated.
Well, that’s all for today! We’ll wrap things up tomorrow by looking at CIM sessions and Windows PowerShell sessions.
~Trevor
That is all there is to invoking CIM methods. CIM Week will continue tomorrow when Trevor will talk about CIM sessions and PS Remoting. | http://blogs.technet.com/b/heyscriptingguy/archive/2014/01/30/invoking-cim-methods-with-powershell.aspx | CC-MAIN-2015-06 | refinedweb | 1,042 | 64.51 |
The board game scrabble works by assigning points to wooden tiles arranged in cells on a board. It's described here:. We'll simplify this considerably, and consider the following question. We begin with the letter-scoring scheme from Scrabble: a = 1, b = 3, c = 3, d = 2, ..., z = 10. Given a text file - a novel for example, and a word size, say 7 characters, what is the highest-(or a highest-) scoring word in the the file of that word size?
Your solution should include two files: A driver, which we provide below, and which you must use, and a file called Scrabble.java, which does the heavy lifting for the application. The Scrabble file should extend Echo, in the standard way we've indicated (it can also extend the LineReader class from Chapter 11 of the text).
Tips:
Make sure you read Chapter 10 of the text as a prelude to doing this problem.
Here is a list from a to z of the letter scores from Scrabble:
{1,3,3,2,1,4,2,4,1,8,5,1,3,1,1,3,10,1,1,1,1,4,4,8,4,10}
It's far easier to convert lines of text to lowercase before processing.
Use a StringTokenizer object to chop up a line into words.
Handle characters that show up inside words, such as apostrophe and hyphen this way: treat a word like "can't" as a five character word, and score the apostrophe as 0. Also, use this String as the second parameter to your StringTokenizer constructor: ",.?! {}[];:". The result of using this String will mean that a word like "students'" (note apostrophe at end) should have length 9.
This is the driver they have given us to use:
import java.util.*; import java.io.*; public class ScrabbleDriver{ public static void main(String args[]) { try{ Scanner s = new Scanner(System.in); System.out.println("enter file name, then word size"); String f = s.next(); int size = s.nextInt(); Scrabble scrab = new Scrabble(f,size); scrab.readLines(); scrab.reportWinner(); } catch(Exception e) {System.out.println(e);} } }
I am not sure how to go about coding this so if anyone could help that would be great. | https://www.daniweb.com/programming/software-development/threads/277249/scrabble-class | CC-MAIN-2018-30 | refinedweb | 369 | 73.07 |

Your loading of the JSON data is a little fragile. Instead of:
json_raw= raw.readlines() json_object = json.loads(json_raw[0])
you should really just do:
json_object = json.load(raw)
You shouldn't think of what you get as a "JSON object". What you have is a list. The list contains two dicts. The dicts contain various key/value pairs, all strings. When you do
json_object[0], you're asking for the first dict in the list. When you iterate over that, with
for song in json_object[0]:, you iterate over the keys of the dict. Because that's what you get when you iterate over the dict. If you want to access the value associated with the key in that dict, you would use, for example,
json_object[0][song].
None of this is specific to JSON. It's just basic Python types, with their basic operations as covered in any tutorial. | https://codedump.io/share/FaUU2kMVrD3k/1/iterating-through-a-json-object | CC-MAIN-2017-34 | refinedweb | 297 | 76.72 |
Notes from Dave Winer’s Session at RSS Winterfest
Published: 01/24/04
On Wednesday, January 21, 2004, I joined Dave Winer, Rick Heller, and Jim Moore at the Berkman Center for Internet & Society for Dave’s talk about RSS during the RSS Winterfest conference. Below are my notes from that session. A transcript of the talk and more materials are available on the wiki for this session.
Dave Winer is the founder of UserLand software and is called the “father of RSS.”
The utility of RSS is what many people don’t realize. Many people focus on the technicalities of it: whether you’re using RDF or namespace or something like that instead of focusing on what it can do. Aggregators are magic.
“What would a presidential campaign that is completely RSS enabled look like?”
There’s a window of time when we can do incredible things. Time in a presidential campaign is compressed more so than in the real world. There’s no business plan. Nothing like that.
There are next steps. It’s a struggle for this community to accept that there are users in this space and that we would all gain if we could make it easier for them to participate, use the technology. Protocols, what do users want from RSS. They want it to be easier. They want more. Today, we are in the early adopter phase of RSS. Everyone who’s a user is also an evangelizer. We’re leaving the layer that’s defined by what the geeks can accomplish and moving into the layer where people who have a vested interest will take over. Competitive advantage to better information flow. While giving them want they want isn’t a technical challenge, it’s difficult to really listen to what they’re saying and strive to really understand it and give them what they’re looking for.
Dave wants the focus of the conference to be on the use of RSS. The technology is fascinating, but the challenges in front of RSS aren’t technological challenges. Users won’t say “We want a better spec for RSS.” They’ll say, “We want it to work better.”
RSS has a certain syntax, regularity.
Dave thinks the RSS spec isn’t going anywhere. It basically is what it is and it isn’t going anywhere. He sees a large installed base developing around that format and people not being concerned with the specs and such.
What happens to campaign blogs after the election? Bob Graham’s blog is already gone.
Questions:
Jeff Jarvis asked for examples of innovative uses for RSS.
After thinking for a moment, Dave responded by saying “Maybe innovation isn’t the right word, but value is.” What’s important is whether people are using RSS for valuable things, not necessarily innovative things.
- Using robots to scrape RSS
- PubSub.com–contains info specific to particular issues by searching thousands of blogs Posted on Scripting News
- weather.com
Someone posted a link to feeds for bargain shopping on the wiki for this session.
He doesn’t want to depend on the monoculture of the big media. He wants RSS to be a distribution point for many people, a decentralized communication system.
Usability is an issue: how can it become mainstream if it isn’t usable. Dave asks, “Does it have to go mainstream?” If RSS were to become mainstream, it has to become mainstream. He thinks it becomes a browser issue. (Over lunch, he explained that he doesn’t mean browsers should necessarily include an aggregator when he says that. He thinks browsers have the ability to make it easier for people to use RSS. He explained two ways that browsers can do this by helping people subscribe to things or by working with someone’s aggregator when they’re online to coordinate subscriptions.)
RSS has been around since 1999. There are things the browser could do to make it easy to use. If we had the source code to MSIE, we could solve the problem.
Rick, Jim, and I were introduced and then we had the opportunity to speak about our interest in RSS.
Rick, a volunteer with Wesley Clark’s campaign, talked about the Clarkbot, a script that searches a database of RSS feeds for mentions of Clark.
Jim, who works for the Dean campaign, talked about using feeds to learn about things happening in real time. He worked with Dave on Channel Dean. Though it’s biased towards Dean stuff, the technology has bigger applications. Jim wants it to be an open platform people can build on top of. Only if RSS is unbiased will people buy into it.
I said, though not as eloquently, that I’m interested in RSS on two levels: as a content creator (thinking of the Web sites and newspaper my office produces) and as a librarian looking to use it to inform myself and as a way for me to inform my clients.
Jim Moore: “You can create a public good, but not actually win in the end.”
Automation is a big thing with computers. RSS is basically easy Web surfing.
Is there going to be an agreement on what RSS stands for?
Netscape invented the term RSS with “site summary” as the SS. Dave thought “site summary” would be confusing. Dave calls it “Really Simple Syndication.” “They’re not really interesting names, let’s put it that way.”
If people have the power to set up their own feeds, does that take away the power of the media companies? What kind of reaction do you think media companies will have as people do this?
Dave answers: at what point do the publishing companies draw the line and say no more power to the users? If the professional reporters don’t cover the stories accurately ? If they want to be competitive, they have to do this. Competitive media companies should do this. It took Martin Nisenholtz of the New York Times a few days to make a decision about it. NYT is a leader in Web stuff. Dave thinks they moved pretty aggressively to do it.
Companies putting ads into RSS is dangerous. The medium is getting commercialized. It will get much more so in the future.
Is RSS like a smart librarian? Dave says it’s more like a dumb librarian or dumb programmer. | http://blogs.harvard.edu/jkbaumga/list-of-longer-pages/notes-from-dave-winers-session-at-rss-winterfest/ | CC-MAIN-2016-40 | refinedweb | 1,062 | 66.94 |

If anyone is interested, here is an article describing ASP+, which is Microsoft's latest rewrite of Active Server Pages:
Some of the improvements are really just eliminating the blatant problems in ASP. But I do find some of these ideas quite compelling, in particular the idea of Web Controls seems particularly useful in making it easier to write dynamic sites that work cross-browser. In a nutshell, it's a "control" that generates matching client-side HTML and server-side code to respond to events, and automatically tailors them for the particular browser being used. You can easily create new Web Controls, too.
Any thoughts on how useful Web Controls are and how something similar could be implemented in Webware?

I looked a little bit at the Mailman internationalisation
code to see how to adapt it to Webware.
(especially Mailman/Defaults.py and Mailman/i18n.py).
The big question is if we want to change the language
after startup or not. The latter case is much
easier. The actual Mailman code uses some
new Python 2.1 features to get the stack frame to serve
as the namespace source. If this fails Mailman falls back
to a _mailman C-module and finally uses a pure Python approach
which works in every supported version of Python.
With that it is possible to write internationalized strings as
follows:
listname = ...
print _('No such list: %(listname)s')
and _ searches for a variable name "listname" automagically
which is a cool feature.
listname = ...
print _('No such list: %(listname)s' % listname)
will not work, because listname is set at runtime
(not at translation time).
The Mailman i18n.py also uses
class SafeDict(UserDict):
"""Dictionary which returns a default value for unknown keys.
This is used in maketext so that editing templates is a bit more
robust.
"""
I put all this stuff into one MiscUtils
file (i18n.py) so one can write
from MiscUtils.i18n import set_language, _
import time
set_language('de')
now = time.ctime(time.time())
print _('The current time is: %(now)s')
print _('Webware is cool!')
I really get
Die aktuelle Zeit ist Mon Mar 12 02:57:57 2001
Webware ist cool!
:-)
I use the following files for that
Webware/locale/de/LC_MESSAGES/webware.mo
Webware/MiscUtils/i18n.py
generated by
pygettext.py -a -o webware.po i18n.py
msgfmt.py webware.po
You can run the example also with
python i18n.py de
The directory names are hardcoded right now, one has to make
this Webware compliant.
---
If one does does not need this runtime translation feature,
then can use the normal _ magic from gettext.
I'm not sure if this dynamic translation is really needed,
but there will hopefully be some feedback..
I attached the 2 files webware.mo and i18n.py for testing..
----------
One could use the same trick for simple templates (no loop, just
filling variables) whitout even having to use a explicit dictionary,
but this is not really fast..

Sorry about the problems you're having. We probably didn't test the
FCGIAdapter enough for the last re;lease as we were concentrating on some
other Adapters.
OK, let me try to answer the questions that don't require me to look at the
code, and if that doesn't fix it, we'll dig in.

Why no, I'm not. I thought FastCGI started the server... but now I'm
realizing there's several different servers in question -- FCGIAdapter
serves connections to FastCGI, but AppServer in turn is the server for
the adapter. Okay.
So, I tried running ./AppServer (as root), but I still get the same
result (FastCGI times out).

Never mind that. Just me being confused.

I tried running the appserver, but it didn't seem to change anything.
WebKit.fcgi is a symbolic link to CFGIAdpater.py, and I made the
changes to httpd.conf more or less like the documentation said.
If I can get this working while understanding what I did, I can write
up more complete install documentation.
Thanks.

Hi Tom,
Yes this looks very interesting and I think we need to be able to switch
languages at run time for the simple reason that different requests can
have different language preferences. e.g., you and I could hit the admin
pages of the same app server, thereby required English and German.
Haven't had a chance to digest the rest of your comments...

The stuff I appended works out of the box,
but has to be refined. Another enhancement would
be to get all translations into memory and then just switch
(see the example in the Python docs) at runtime. That seems much
better than just overriding _translation each time.
For big sites this could of course blow up
the memory usage so a translation sweeping could
be a solution, but I'm not sure how big this stuff gets.

I knew that would get you excited!
But my comments weren't entirely facetious. The MySQL guys seem to have at
least provided several conveniences (like the ones described above) that
eluded the other database designers.

However it is at higher complexity build files (medium->high complexity)
where the advantage would be shown. Mainly as it would allow core to be
clean and handling of tasks predictable. For big build processes it would
allow customisation without magic variables (ala GUMPs sysclasspath) and
added value (ie assign fee: namespace to something specific to buisness). |

Hello Adobe Forums, I hope this post finds you well.
Flex n00ber here and I sure could use some help understanding this process. It's killin' me!
I have a ComboBox being populated by a system service array of values. (getSystems())
I also have a multi-select enabled spark List being populated by a different service. (getIterations())
The label values for the spark list are just numbers 1 through 15.
What I'm trying to achieve:
When I select a system in the cbo box, I need to call a service that returns an array of the values associated with that selected system and then programmatically select those values in the spark list.
I do have a service that returns an array of that data based on the value of the cboBox.selectedItem.sysID. (getIterationsBySysID())
What does it take to make this happen?
I hope I explained this in a meaningful way.
ciao,
-aaron
Hi
Just set the selected items property of the list control with the array thet u are getting from the service or
match the service results with the complete data in list and find the index of each and every item that has been returned from the service and
push the index values to an array and assign the array to the selected indices property of list .
This will show all the index values as selected.
So that's the 1000 foot view, you make it sound easy... =/
Thanks for reading my post selvakumar p.
Will someone help me understand how to first make an array of results from a service?
Should I make a new service to ONLY bring back the int's I plan on using for the selected index or is it ok to bring back three values with one being the index int I want to use?
If three things are coming back into an array all how do I specify I want the first index item to be used as the selected indexes? [0]
I guess my real disconnect (besides having little AS knowledge) is not knowing the correct way to generate an array of values based on the change event of a control and then calling that set of values within another control as the selectedIndices.
I've been loving it (Flex) up until this point, but now I'm thoroughly frustrated.
I'm going back to google to see if I can find that one tutorial.
The computer I'm building this on does not have internet connectivity.
I'm going to hand jam all of the code I'm using in a sample application I've built for this one problem.
The setup:
1 spark List
1 Combo Box
One service populates the list.
One service populates the Combo Box.
One service passed the variable containing a systemID from the selectedItem in Combo Box.
The list selectedIndices should be the result of the service with variable call.
Here's the code I'm using.
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:
<fx:Script>
<![CDATA[
import mx.controls.Alert;
import mx.events.FlexEvent;

}
protected function comboBox_creationComplete(event:FlexEvent):void
{
getAllSystemResult.token = systemService.getAllSystem();
}
protected function comboBox_changeHandler(event:IndexChangeEvent):void
{
getCDRTbySysIdResult.token = systemService.getCDRTbySysId(comboBox.selectedItem.sysID);
}
]]>

<s:CallResponder
</fx:Declarations>
<s:List
<s:AsyncListView
</s:List>
<s:ComboBox
<s:AsyncListView
</s:ComboBox>
</s:Application>
Please someone enlighten me on what part I'm missing here.
And thank the gods it's Friday!
-aaron
Set a result event on the service that gets the list selection items.
Have that event push the selectedIndices with this 'magical' loop. LOL (I call it magic because it had me mystified for two days!)
private function onCatResult(e:ResultEvent):void {
var v:Vector.<int> = new Vector.<int>();
for(var i:int = 0;i<e.result.length;++i) {
//Alert.show("Selecting " + e.result[i].cdrtID);
v.push(e.result[i].cdrtID -1);
}
MyList.selectedIndices = v;
}
I had to subtract one from the pushed value in order to compensate for the zero based index of the returning array.
Hopefully this will help someone in the future, I certainly struggled with it.
ciao,
-aaron
spark.components.List has
spark.components.SkinnableDataContainer in its class hierarchy which dispatches a
dataProviderChanged event whenever the dataProvider changes. Unfortunatly there is no
[Event] metadata in
SkinnableDataContainer that allows using this event in MXML. So, you'll need to create your own custom component that extends
List.
package
{
import spark.components.List;
[Event(name="dataProviderChanged", type="flash.events.Event")]
public class MyList extends List
{
public function MyList()
{
super();
}
}
}
This works with other
List-based components (like
DropDownList) too.

How to create custom components in CSharp (C#)Hello everyone, in this article we are going to talk about how can we create a custom component in Visual Studio and C#. We are going to make a custom digital clock example.
Let's get started.
I always keep my projects tidied up. First create a folder in your project. We are going to create our components classes in this folder. Below image you can find how can we do it.
And then add a Custom Control in this folder. This control class will be our component. Below image you can find it.
Below code block will be generated automatically:
namespace CustomComponentExample.TheComponent { partial class DigitalClock { /// } }
We are going to need some variables in this example. We will make a digital clock component. We will define hour, minute and second variables. We will show them in our component now.
//we will update this variables from upper class. public int val_hour = 0; public int val_minute = 0; public int val_second = 0; //we do not need this update from upper class so define as private private string current_clock = "00:00:00";
We are going to show somethingon our form. It means we are going to paint something on form. So we need to add a protected function below to paint our component :
protected override void OnPaintBackground(PaintEventArgs pevent) { base.OnPaintBackground(pevent); }
Now we are ready to show something on screen. Below code block will draw the clock information on screen.
//we will update this variables from upper class. public int val_hour = 0; public int val_minute = 0; public int val_second = 0; private string str_hour = "00"; private string str_minute = "00"; private string str_second = "00"; //we do not need this update from upper class so define as private private string current_clock = "00:00:00"; protected override void OnPaintBackground(PaintEventArgs pevent) { base.OnPaintBackground(pevent); //To prevent painting single character... str_hour = val_hour < 10 ? "0" + val_hour : val_hour.ToString(); str_minute = val_minute < 10 ? "0" + val_minute : val_minute.ToString(); str_second = val_second < 10 ? "0" + val_second : val_second.ToString(); current_clock = str_hour + ":" + str_minute + ":" + str_second; pevent.Graphics.DrawString(current_clock, new Font("Comic Sans MS", 32), Brushes.Black, new PointF(0, 0)); } //This function is required to refresh this component public void refreshClock() { this.Refresh(); }
Now let's write some code to show current time on the screen. So what we will do now.
We are going to declare a Timer and set the interval as 1000ms. It will update the clock every 1 second. Below code block will do this.
Timer tmrClock; private void Form1_Load(object sender, EventArgs e) { tmrClock = new Timer(); tmrClock.Interval = 1000; tmrClock.Tick += TmrClock_Tick; tmrClock.Start(); } private void TmrClock_Tick(object sender, EventArgs e) { digitalClock1.val_hour = DateTime.Now.Hour; digitalClock1.val_minute = DateTime.Now.Minute; digitalClock1.val_second = DateTime.Now.Second; digitalClock1.refreshClock(); }
Maybe you will need some functions inside your component. If you need that you have to add component inside your namespace. In this case I will do as below:
using CustomComponentExample.TheComponent;
That is all in this article.
Have a good creating custom components

Let me start this blog by confessing that I am a Java guy who first learned Python three years back but haven’t used it much in my day to day work. So, after three long years, I have decided to brush up on my Python skills by developing a simple web application. By simple I don’t mean “Hello World” application but an application which does some work like storing data to a database. After spending some time googling “best web framework in Python,” I zeroed in on Flask. Flask is a microframework for Python based on Werkzeug and Jinja 2. It is a very easy to learn framework and is based on convention over configuration, which means that many things are preconfigured with sensible defaults. as shown below.
Prerequisite
Before we can start building the application, we’ll have to do few setup tasks :
- Basic Python knowledge is required.
- Sign up for an OpenShift Account. It is completely free and instant ..
Source code of the application that we will be developing in this blog is on github
Step 1 : Create an OpenShift Python Application
We will start by creating an OpenShift Python 2.7 application. OpenShift also supports Python 2.6 and Python 3.3, but for this blog we will be sticking with Python 2.7. To learn more about the Python 3.3 cartridge, please refer to this blog.
The OpenShift Python 2.7 cartridge by default uses mod_wsgi Apache HTTP Server module that provides a WSGI compliant interface for hosting Python based web applications under Apache.To create a Python 2.7 application named todo, type the command shown below.
$ rhc app create todo python-2.7 postgresql-9.2
The command shown above will create an application container for us, called a gear, and setup all of the required SELinux policies and cgroup configuration. Next, it will install all the required software on your gear. It will also install PotsgreSQL 9.2 on your application gear and will create a database with the same name as the application name. OpenShift will also setup a private git repository with some template code, and then clone the repository to your local system. Finally, OpenShift will propagate the DNS to the outside world.
You can view the application details using the command shown below.
$ rhc show-app --app todo todo @ (uuid: 522425cd500446b3ec000294) ------------------------------------------------------------------------------- Domain: xxxxx Created: 11:14 AM Gears: 1 (defaults to small) Git URL: ssh://522425cd500446b3ec000294@todo-xxxxx.rhcloud.com/~/git/todo.git/ SSH: 522425cd500446b3ec000294@todo-xxxx.rhcloud.com python-2.7 (Python 2.7) ----------------------- Gears: Located with postgresql-9.2 postgresql-9.2 (PostgreSQL Database 9.2) ---------------------------------------- Gears: Located with python-2.7 Connection URL: postgresql://$OPENSHIFT_POSTGRESQL_DB_HOST:$OPENSHIFT_POSTGRESQL_DB_PORT Database Name: todo Password: AXtK_CELQXJK Username: adminiid3lsl
Step 2 : Look at Default Template Application
The default structure of the template application created by OpenShift is shown below.
todo wsgi/ Externally exposed wsgi code goes here wsgi/static/ Public static content gets served here libs/ Additional libraries data/ For not-externally exposed wsgi code setup.py Standard setup.py, specify deps here app.py.disabled This file may be used instead of Apache mod_wsgi to run your python web application in a different framework .openshift/ Location for OpenShift specific files action_hooks/ Various scripts to hook into application lifecycle markers/ Marker files for hot deployment , debugging etc
All the application code will be placed in the wsgi folder and application dependencies will be added to setup.py.
Step 3 : Adding Flask and Flask-SQLAlchemy Dependencies
OpenShift uses Setuptools which is a collection of enhancements to the Python distutils , that allow developers to more easily build and distribute Python packages, especially ones that have dependencies on other packages. We will add Flask and Flask-SQLAlchemy dependencies to setup.py as shown below.
from setuptools import setup setup(name='TodoApp', version='1.0', description='Todo Application', author='Shekhar Gulati', author_email='', url='', install_requires=['Flask==0.7.2', 'MarkupSafe' , 'Flask-SQLAlchemy==0.16'], )
The key attribute in the code shown above is install_requires=[‘Flask==0.7.2’, ‘MarkupSafe’ , ‘Flask-SQLAlchemy==0.16’]. The install_requires attribute is used to specify a list of strings that represent python modules that your app needs. If you need other modules that are not listed you can just add new elements to setup.py. The reason we pegged to a certain version is 1) this prevents the build from checking versions with every git push and 2) it also prevents a build from putting in a version that breaks our code without our knowledge.
Step 4 : Make Flask Say Hello
We will start developing our todo application by creating a new file called todoapp.py in wsgi folders. On windows you can just create a new file named todoapp.py, by right clicking in explorer and saying new text file, then change .txt extension with .py extension.
$ cd wsgi $ touch todoapp.py
Open your favorite editor and add following lines to it.
from flask import Flask app = Flask(__name__) @app.route('/') @app.route('/hello') def index(): return "Hello from OpenShift" if __name__ == '__main__': app.run()
The code shown above does following :
- Import the Flask class from the flask module and then create an instance of Flask class. This instance will be our WSGI application.
- Next we define a route which tells Flask that on root(‘/’) and home(‘/home’) url, it should invoke index() function. The index() function just simply returns “Hello from OpenShift” string which will be rendered by the browser.
- Finally, if the name of the application module is equal to “_ _main_ _” then run method is invoked to run the server.
The last change needed to make this “Hello World” application work on OpenShift is to update a file named application which OpenShift created under wsgi folder. Change the content of the file with the one shown below.
#!/usr/bin/python import os virtenv = os.environ['OPENSHIFT_PYTHON_DIR'] + '/virtenv/' os.environ['PYTHON_EGG_CACHE'] = os.path.join(virtenv, 'lib/python2.7/site-packages') virtualenv = os.path.join(virtenv, 'bin/activate_this.py') try: execfile(virtualenv, dict(__file__=virtualenv)) except IOError: pass from todoapp import app as application
The application file is required by OpenShift and it basically calls the todoapp file that we created earlier.
After all the code changes are done, add the code to the git repository, commit it, and push it to OpenShift gear.
$ git add . $ git commit -am "hello world from flask" $ git push
The application will be accessible at-{domain-name}.rhcloud.com. Replace {domain-name} with your domain name.
Step 5 : Defining your Model
In this blog, we are using Flask-SQLAlchemy which is a Flask extension that adds SQLAlchemy support to our todoapp application. SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL.
Open the todoapp.py and add Todo model class to it as shown below.
from datetime import datetime from flask import Flask from flask_sqlalchemy import SQLAlchemy app = Flask(__name__) app.config.from_pyfile('todoapp.cfg') db = SQLAlchemy(app) class Todo(db.Model): __tablename__ = 'todos' id = db.Column('todo_id', db.Integer, primary_key=True) title = db.Column(db.String(60)) text = db.Column(db.String) done = db.Column(db.Boolean) pub_date = db.Column(db.DateTime) def __init__(self, title, text): self.title = title self.text = text self.done = False self.pub_date = datetime.utcnow() @app.route('/') @app.route('/hello') def index(): return "Hello from OpenShift" if __name__ == '__main__': app.run()
In the code shown above we made the following additions.
- First we imported SQLAlchemy class from flask_sqlalchemy module. This is required to work with Flask-SQLAlchemy.
- Then we created an instance of SQLAlchemy class by passing it application object. The application object was loaded with database configuration which we specified in todoapp.cfg file. We will be creating todoapp.cfg later in this post.
- Next we defined our Todo model by extending db.Model class and declaring all the Todo model attributes.
Next, create a new file called todoapp.cfg in wsgi folder. It will house all our application configuration. On windows you can just create a new file named todoapp.cfg, by right clicking in explorer and saying new text file, then change .txt extension with .cfg extension.
$ cd wsgi $ touch todoapp.cfg
Add following lines to todoapp.cfg
import os SQLALCHEMY_DATABASE_URI = os.environ['OPENSHIFT_POSTGRESQL_DB_URL'] SQLALCHEMY_ECHO = False SECRET_KEY = 'secret key' DEBUG = True
Once you go into production, you will probably want to turn off DEBUG until you run into problems. This will help with performance since you won’t be writing as much to files.
Update the application file under wsgi folder so that it creates the database. Add the two lines at the end of file.
from todoapp import * db.create_all()
Step 6 : Persisting Todo Items to PostgreSQL
Next we will add a route “/new” which will render a form when a user makes a get request to-{domain-name}.rhcloud.com/new. And when user submit the form using POST method it will write the todo item to database.
Add following lines to todoapp.py.
from flask import Flask, request, flash, url_for, redirect, render_template, abort @app.route('/new', methods=['GET', 'POST']) def new(): if request.method == 'POST': todo = Todo(request.form['title'], request.form['text']) db.session.add(todo) db.session.commit() return redirect(url_for('index')) return render_template('new.html')
Flask uses Jinja2 as its templating language. For those of you new to the flask framework, templates basically facilitate the seperation of presentation and processing of your data. Templates are web pages that have mostly static elements and integrate programming logic which produces dynamic content. In the code snippet shown above we are rendering a template called ‘new.html’. Create a new folder called templates under wsgi folder and create a new.html in it and add the following lines.
$ cd wsgi $ mkdir templates $ cd template $ touch new.html
Next copy the content shown below in new.html.
{% extends "layout.html" %} {% block body %} <form action="" method=post <h2>Create New Todo</h2> <div class="control-group"> <div class="controls"> <input type="text" id="title" name="title" class="input-xlarge" placeholder="Please give title to todo item" value="{{ request.form.title }}" required> </div> </div> <div class="control-group"> <div class="controls"> <textarea name="text" rows=10 <div class="controls"> <button type="submit" class="btn btn-success">Create Todo</button> <a href="{{ url_for('index') }}">Back to list</a> </div> </div> </form> {% endblock %}
The new.html template extends another template called layout.html. The layout.html is where we will define the layout of our web application. Create a new file called layout.html in the templates folder under wsgi and following content. Basically, template inheritance makes it possible to keep certain elements on each page like header, footer, etc.
<!doctype html> <title>TodoApp -- Store your Todo items</title> <meta name="viewport" content="initial-scale=1.0, user-scalable=no"> <meta charset="utf-8"> <style> body { padding-top: 60px; padding-bottom: 100px; } </style> <link href="/static/bootstrap.css" rel="stylesheet"> <link href="/static/bootstrap-responsive.css" rel="stylesheet"> <script src="/static/jquery.js"></script> <script src="/static/bootstrap.js"></script> ="/">TodoApp</a> <div class="nav-collapse collapse"> <ul class="nav"> <li class="active"><a href="/">Home</a></li> <li><a href="/new">New Todo</a></li> </ul> </div> <!--/.nav-collapse --> </div> </div> </div> {%- for category, message in get_flashed_messages(with_categories=true) %} <p class="flask {{ category }}-flash">{{ "Error: " if category == 'error' }}{{ message }}</p> {%- endfor %} <div id="main" class="container"> {% block body %}{% endblock %} <hr> <footer id="footer"> <p>Todo App built using Flask, SQLAlchemy, PostgreSQL , and Twitter Bootstrap</p> <p><a href="" target="_blank"><img alt="Powered by OpenShift" src=""></a></p> </footer> </div>
Flask will look for templates in the templates folder. Templates have access to request, session, g objects, as well as the get_flashed_messages() function. We have used get_flashed_messages() method above. This method pulls all flashed messages from the session and returns them. As Flask configured Jinja2 templating engine for our application, HTML escaping is also enabled for the application. This makes sure the application is secure. You should head over to Jinja2 official documentation for more information.
The project uses Twitter bootstrap to beautify the application. Copy the files from and put in static folder under wsgi. The static folder is for serving static files.
$ cd ../static $ wget $ wget $ wget $ wget
Commit the code and push it to OpenShift gear
$ git add . $ git commit -am "added functionality to create a new todo" $ git push
Now if you go to-{domain-name}.rhcloud.com/new you will see a form where you can create todo items as shown below.
Next, create a new Todo item by entering some details and pressing “Create Todo” button. The application will first save the todo item and then redirect you to index “/” page. To view the persisted todo item we will log into our application gear and run psql PostgreSQL client.
$ rhc ssh --app todo $ [todo-xxxx.rhcloud.com 5204d6c75973cac7a00001ef]\> psql psql (9.2.4) Type "help" for help. todo1=# \dt List of relations Schema | Name | Type | Owner --------+-------+-------+-------------- public | todos | table | adminwrqfzbx (1 row) todo1=#
To view the created todo item we will run select query as shown below.
todo1=# select * from todos; todo_id | title | text | done | pub_date ---------+-----------------------+--------------------------+------+---------------------------- 1 | Learn Flask framework | Read Flask Documentation | f | 2013-08-10 02:51:43.007073 (1 row) todo1=#
Step 7 : View all Todo Items on Index Page
The next feature that we are going to implement is to show all the todo items on the index page. So, if a user goes to-{domain-name}.rhcloud.com/ then he/she will see all the todo items.
Update the index() function in todoapp.py with the following lines:
@app.route('/') def index(): return render_template('index.html', todos=Todo.query.order_by(Todo.pub_date.desc()).all() )
Create a new file called index.html in the templates directory and add the following content:
{% extends "layout.html" %} {% block body %} <div id="main" class="container"> <h2>All Items</h2> <table class="table table-hover"> <tr> <th># <th>Title <th>Date <th>Text {%- for todo in todos %} <tr class={{ "success" if todo.done }}> <td><a href="/todos/{{ todo.id }}">{{ todo.id }}</a> <td style={{ "text-decoration:line-through" if todo.done }}>{{ todo.title }} <td>{{ todo.pub_date.strftime('%Y-%m-%d %H:%M') }} <td>{{ todo.text }}</td> {%- endfor %} </table> <p> <a href="{{ url_for('new') }}" class="btn btn-large btn-primary">New Todo</a> </div> {% endblock %}
Commit the changes and push to OpenShift gear.
$ git add . $ git commit -am "added index()" $ git push
Now if you go to-{domain-name}.rhcloud.com , you will see as shown below. Please replace {domain-name} with your own domain name.
Step 8 : View and Update a Todo Item
The next functionality that we are going to implement is viewing and updating a specific todo item. When a user goes to-{domain-name}.rhcloud.com/todos/1 then he/she should see a form filled with details of todo item with id 1. A user can change the values and submit the form again. This will update the values of the todo item. A user can update the todo item to mark todo as done. Add a new function to todoapp.py as shown below.
@app.route('/todos/<int:todo_id>', methods = ['GET' , 'POST']) def show_or_update(todo_id): todo_item = Todo.query.get(todo_id) if request.method == 'GET': return render_template('view.html',todo=todo_item) todo_item.title = request.form['title'] todo_item.text = request.form['text'] todo_item.done = ('done.%d' % todo_id) in request.form db.session.commit() return redirect(url_for('index'))
The view.html template is shown below. Create a new file with name view.html in templates directory and place the content shown below in it.
{% extends "layout.html" %} {% block body %} <form action="" method=post <h2>Create New Todo</h2> <div class="control-group"> <div class="controls"> <input type="text" id="title" name="title" class="input-xlarge" placeholder="Please give title to todo item" value="{{ todo.title }}" required> </div> </div> <div class="control-group"> <div class="controls"> <textarea name="text" rows=10 <div class="controls"> <input type=checkbox name=done.{{ todo.id }}{{ " checked" if todo.done }}> </div> </div> <div class="control-group"> <div class="controls"> <button type="submit" class="btn btn-success">Update Todo</button> <a href="{{ url_for('index') }}">Back to list</a> </div> </div> </form> {% endblock %}
Commit the code and push it to OpenShift gear.
$ git add . $ git commit -am "added view or update functionality" $ git push
Now if you go to-{domain-name}.rhcloud.com/todos/1 then you will see a todo item as shown below.
You can mark the checkbox and press “Update todo” and you will see the todo marked done on the index page.
Conclusion
In this blog we covered how developers can build web applications in Python using Flask framework and PostgreSQL database and deploy it to OpenShift. If you are looking to host your Python application. | https://blog.openshift.com/build-your-app-on-openshift-using-flask-sqlalchemy-and-postgresql-92/ | CC-MAIN-2017-22 | refinedweb | 2,809 | 59.6 |
A runtime type checker (contract system) and JSON validator
Project description
Obiwan is also exemplary for describing and checking external data e.g. JSON and msgpack, and has a json parser that does this.
Obiwan machinary can also be used for checking contracts, constraints and expectations in normal code rather as an assert.()
(Obiwan attaches to the Python VM using settrace(). You need to call the installer in each thread you want checked)
you are now running obiwan! Runtime execution will be slower, but annotated functions will be checked for parameter correctness!
All strings in your function annotations are ignored;(obj: {"a":int, "b": float}) -> {"ret": number}: return {"ret": a/b}
Checking can support the checking of optional and noneable attributes:
def example(obj: {"a":int, optional("b"): float}): ...
Checks can contain dictionary and other attributes too:
def example(person: {"name":str, "phone": {"type":str, "number":str}}): ...
Dictionaries can be checked for key and value types, as well as by key name. E.g. to ensure that a function returns only dictionaries mapping strings to integers:
def example() -> {str: int}: ...
You can specify alternative constraint types using sets:
def example(x: {int,float}): ...
In fact, number type is just a set of int and float. And noneable is just a way of saying {...,None}
Lists mean that the attribute must be an array where each element matches the constraint e.g.:
def example(numbers: [int]): ...
And sets which must be all of one type can be specified with a set containing a single element:
def example(x: {str}): ...]) json.loads(tainted, template={"type": str, "data": { ....(a: duck(name=str,get_name=function)): ...
This means that a must be something with a name attribute of type string, and a function attribute called get_name.
You can of course use classes to:
class Person: def get_name(self): ... def example(callback: function): ...
If you want, you can describe the parameters that the function should take:
def example(callback: function(int,str)): ...
However, all the functions passed to example8 must now be properly annotated with a matching annotation.
The special type any can be used if you do not want to check the type:
def example(callback: function(int,any,number)): ...
You can also specify that a function should support further arguments using ellipsis:
def example.

In the spirit of improving my software engineering practices I have been trying to make more use of the Python logging module. In common with many programmers my first instinct when debugging a programming problem is to use print statements (or their local equivalent) to provide an insight into what my program is up to. Obviously, I should be making use of any debugger provided but there is something reassuring about the immediacy and simplicity of print.
A useful evolution of the print statement in Python is the logging module which can be used as a simple print function but it can do so much more: you can configure loggers for different packages and modules whose behaviour can be controlled centrally; you can vary the verbosity of your logging messages. If you decide to switch to logging to a file rather than the terminal this can be achieved too, and you can even post your log messages to a website using HTTPhandler. Obviously logging is about much more than debugging.
I am writing this blog post because, as most of us have discovered, using logging is not quite as straightforward as we were led to believe. In particular you might find yourself in the situation where you feel you have set up your logging yet when you run your code nothing appears in your terminal window. Print doesn’t do this to you!
Loggers are arranged in a hierarchy. Loggers have handlers which are the things that cause a log to generate output to a device. If no log is specified then a default log called the root log is used. A logger has a name and the hierarchy is defined by the dots in the name, all the way “up” to the root logger. Any logger can have a handler attached to it, if no handler is attached then any log message is passed to the parent logger.
A log record has a message (the thing you would have printed) and a “level” which indicates the severity of the message these are specified by integers for which the logging module provides convenient labels. The levels in order of severity are logging.DEBUG, logging.INFO, logging.WARNING, logging.ERROR, logging.CRITICAL. A log handler will output a message if the level of the message is equal to or more than the level it has been set to. So a handler set to WARNING will show messages at the WARNING, ERROR and CRITICAL levels but not the INFO and DEBUG levels.
The simplest way to use the logging module is to import the library:
import logging
Then carry out some minimal configuration,
logging.basicConfig(level=logging.INFO)
and then put logging.info statements in our code, just as we would have done with print statements:
logging.info("This is a log message that takes a parameter = {}".format(a_parameter_value))
logging.debug, logging.warning, logging.error and logging.critical are used to publish log messages with different levels of severity. These are all convenience methods which remove the need to explicitly give the level as found in the logging.log function:
logging.log(logging.INFO, "This is a log message")
If we are writing a module, or other code that we anticipate others importing and running then we should create a logger using logging.getLogger(__name__) but leave configuring it to the caller. In this instance we use the name of the logger we have created instead of the module level “logging”. So to publish a message we would do:
logger = logging.getLogger(__name__) logger.info("Hello")
In the module importing this library you would do something like:
import some_library logging.basicConfig(level=logging.INFO) # if you wanted to tweak the levels of another logger logger = logging.getLogger("some other logger") logger.setLevel(logging.DEBUG)
basicConfig() configures the root logger which is where all messages end up in the absence of any other handler. The behaviour of logging.basicConfig() is downright obstructive at times. The core of the problem is that it can only be invoked once in a session, any future invocations are ignored. Worse than this it can be invoked implicitly. So if for example you do:
import logging logging.warning("Hello")
You’ll see a message because secretly logging has effectively run logging.basicConfig(level=logging.WARNING) for you (or something similar). This means that if you were to then naively go ahead and run basicConfig yourself:
logging.basicConfig(level=logging.INFO)
You would see no message when you subsequently ran logging.info(“Hello”) because the “second” invocation of logging.basicConfig is ignored.
We can explicitly set the properties of the root logger by doing:
root_logger = logging.getLogger() root_logger.setLevel(logging.INFO)
You can debug issues like this by checking the handlers to a logger. If you do:
import logging lgr = logging.getLogger() lgr.handlers
You get the empty list []. Issue a logging.warning() message and you see that a handler has been added to the root logger, lgr.handlers() returns something like [<logging.StreamHandler at 0x44327f0>].
If you want to see a list of all the loggers in the hierarchy then do:
logging.Logger.manager.loggerDict
So there you go, the logging module is great – you should use it instead of print. But beware of the odd behaviour of logging.basicConfig() which I’ve spent most of this post griping about. This is mainly so that I have all my knowledge of logging in one place rather than trying to remember which piece of code I pulled off a particular trick.
I used the logging documentation here, blog posts by Fang (here) and Praveen Gollakota (here) and tab completion in the ipython REPL in the preparation of this post. | http://www.ianhopkinson.org.uk/tag/python/ | CC-MAIN-2019-47 | refinedweb | 950 | 56.25 |
So, my intuition of shadowing of functions is that the compiler will prefer the version from my module unless the arguments don't match, but if I shadow
import func Foundation.puts private extension StaticString { @_transparent var cString: UnsafePointer<CChar> { UnsafeRawPointer(utf8Start) .assumingMemoryBound(to: CChar.self) } } func print(_ string: StaticString) { puts(string.cString) } // Calls Swift.print, and does a surprisingly large amount of work to print // something that should constant propagate to a zstring and a count. print("Hello, world!")
It calls
Swift.print instead of my version that delegates to
puts. That would make me think that maybe the compiler just prefers
String to
StaticString, except that if I wrap the definition and call of
do { func print(_ string: StaticString) { puts(string.cString) } // Calls my print and constant propagates "Hello world!" into a zstring print("Hello, world!") }
So, in short, I have no idea how the compiler decides which version of a shadowed function to use. | https://forums.swift.org/t/confused-about-shadowing-of-functions-from-another-module/47270 | CC-MAIN-2021-31 | refinedweb | 159 | 58.28 |
Literally, latch means a device for keeping a door or gate closed. Its meaning is analogous to a gate in Java as well. So if latch (gate) is open, everyone can pass through it but when it's shut, no one is allowed to cross over. With this as background let's go in detail:
It's one of the advanced threading/concurrency concepts of Java. Java provides a Latch API named as CountDownLatch which got introduced in Java 5 ( java.util.concurrent package). So now on; I will refer Latch and CountDownLatch interchangeably to refer to the same thing. Latch is a synchronizer that can delay the progress of threads until it reaches its terminal state. [A synchronizer is any object that coordinates the control flow of threads based on its state] So it is used to synchronize one or more tasks by forcing them to wait for the completion of a set of operation being performed by other tasks.
CountDownLatch in actionLet me start directly with a simple example to stress on the fundamentals of this API. Below sample program has two tasks (as taskone() and tasktwo()) represented as methods. And I want to make sure that taskone() should get completed before tasktwo().
import java.util.concurrent.CountDownLatch; import java.util.concurrent.TimeUnit; public class CountDownLatchTest { static CountDownLatch latch; CountDownLatchTest(final int count) { latch = new CountDownLatch(count); } public void firstTask() { Runnable s1 = new Runnable() { public void run() { try { System.out.println("waiting...."); TimeUnit.SECONDS.sleep(5); } catch (InterruptedException e) { e.printStackTrace(); } // finish first activity before last line latch.countDown(); } }; Thread t = new Thread(s1); t.start(); } public void secondTask() { Runnable s2 = new Runnable() { public void run() { try { System.out.println("wait...."); latch.await(); // perform task here System.out.println("after wait.... done"); } catch (InterruptedException e1) { e1.printStackTrace(); } } }; Thread t = new Thread(s2); t.start(); } public static void main(String[] args) throws InterruptedException { CountDownLatchTest cdlt = new CountDownLatchTest(1); cdlt.secondTask(); TimeUnit.SECONDS.sleep(5); cdlt.firstTask(); } }
Output:
wait....
waiting....
after wait.... done
waiting....
after wait.... done
Above example shows CountDownLatch attribute getting initialized to a value of 1 through constructor. Two tasks in above example are synchronized though CountDownLatch. Task2 i.e. secondTask() should wait for completion of Task1 i.e. firstTask(). Run above example and notice the sequence in which output appears on the console.
Please note few important points
- Any task that calls await() on the object will block until the count reaches zero or it's interrupted by another thread. secondTask() gets blocked after call to await(); evident from output.
- Call countDown() on the object to reduce the count. The task that call countDown() are not blocked. This cal signals the end of the task. This method need to be called at the end of the task.
- As soon as count reaches zero; threads awaiting starts running.
- The value of count which is passed during creation of latch object is very important. It should be same as the number of task which needs to be finished first. If count is 5 then first task should be called five times to make sure that count has reduced to 0.
- You can also use wait and notify mechanism of Java to achieve the same behavior but code will become quite complicated.
- One of the disadvantage of CountDownLatch is that its not reusable once count reaches to zero. But Java provides another concurrency API called CyclicBarrier for such cases.
Usage of CountDownLatch
- Use this when your current executing thread/main thread needs to wait for the completion of other dependent activities.
- Ensure that a service doesn't start until other services on which it depends have not completed.
- In a multi-player game like RoadRash; wait for all players to get ready to start the race.

Here is a screenshot of my kivy app. I am trying to get the
TextInput
BoxLayout
BoxLayout
TextInput
center:self.parent.center
BoxLayout
TextInput
TextInput
import kivy
from kivy.app import App
from kivy.uix.widget import Widget
from kivy.uix.label import Label
from kivy.uix.boxlayout import BoxLayout
class TimeTabler(Widget):
pass
class TimerApp(App):
def build(self):
return TimeTabler()
if __name__ == "__main__":
TimerApp().run()
#:kivy 1.0
BoxLayout:
orientation: 'vertical'
size: root.size
BoxLayout:
orientation: 'vertical'
Label:
text: 'TimeTabler'
BoxLayout:
TextInput:
text: '%s' % (self.parent.center) # why does this work here
size_hint: None, None
width: sp(200)
height: sp(30)
center: self.parent.center # but not here
You gave the TextInput
size_hint: None, None, therefore the BoxLayout doesn't try to manually give it the right size, and it assumes the default size of
100, 100. Just delete the
size_hint line to fix it.
Also, several widgets have lines like
size: self.size. This is meaningless,
self refers to the widget itself, and clearly the line does nothing since it just tries to set the size to what it already is.
Things would also be simpler if you made your TimeTabler inherit from BoxLayout instead of Widget. That way you wouldn't need to manually set it's child BoxLayout's size.
Edit: It looks like I misunderstood what you wanted, here's an example that uses an AnchorLayout to center the TextInput:
<TimeTabler> BoxLayout: orientation: 'vertical' size: root.size on_touch_down: print self.pos, self.size canvas: Color: rgba: 0, 1, 1, .3 Rectangle: size: self.size pos: self.pos BoxLayout: orientation: 'vertical' size: self.size Label: text: 'TimeTabler' BoxLayout: id: bl on_touch_down: print 'center', self.center canvas: Color: rgb: 1,1,1 Line: rectangle: self.x, self.y, self.width, self.height AnchorLayout: TextInput: size_hint: None, None text: '%s, %s' % (self.get_center_x(), self.get_center_y())
I think your problem was the BoxLayout automatically sets the position of the TextInput even when it is setting its own size. A simple way around this is to just next the TextInput in another widget, in this case an AnchorLayout that takes care of the centering for you. You could also just use a Widget and your previous mechanism of setting the TextInput center. | https://codedump.io/share/zRTQaOZd5Eii/1/centering-textinput-within-a-boxlayout-in-kivy | CC-MAIN-2017-26 | refinedweb | 373 | 59.9 |
Today we get to take on one of the core items of object-oriented programming, inheritance. Particularly the dangers of inheritance and what is a better way in many cases. Inheritance is a core part of what makes object-oriented great and powerful when used correctly. What we will go over in this blog post is a particular pattern that gives us some of the capabilities of inheritance, while keeping us safe and maintaining encapsulation.
First off, there are a couple of different types of inheritance; the first is implementation inheritance which is one class extends the functionality of another class. This is the type of inheritance we will be talking about in this blog post. There is also interface inheritance where a class implements an interface or one interface extends another interface. This second type of inheritance is not covered in this blog post.
The core of what the title of this blog post comes down to is that inheritance breaks encapsulation. The problem comes in that changes to the super class can cause issues in the sub-classes without the sub-classes realizing it. This can lead to breakage, unexpected data leakage, and other issues that would best be avoided. This means the sub-classes need to evolve in lock step with their parent classes or risk encountering issues.
Let's look at an example, and although contrived, the example in the book is solid at showing the issues. The idea behind this example class is that it creates a method for a user to have a
HashSet that can retrieve how many times an item was added to it. Let's take a look.
@NoArgsConstructor public class InstrumentedHashSet<E> extends HashSet<E> { @Getter private int addCount = 0; public InstrumentedHashSet(int initCap, float loadFactor) { super(initCap, loadFactor); } @Override public boolean add(E e) { addCount++; return super.add(e); } @Override public boolean addAll(Collection<? extends E> c) { addCount += c.size(); return super.addAll(c); } }
This implementation, although it looks reasonable, has an issue that you won't discover until you realize how the implementation of
HashSet works. Under the hood
addAll simply calls
add to insert elements so when you perform the call
myCoolInstrumentedHashSet.addAll(List.of("a","b","c")) you end up with an
addCount of
6 not
3 like you would expect. Three get added in the
addAll call and 3 get added in the
add call. There are ways to "fix" this issue, like removing the code in the
addAll call, but that is still making it dependent on the implementation of the class. While it works today, will it work tomorrow?
In addition to the coupling discussed above, there are other issues with using inheritance when it comes to fragility. As time goes on various things can happen to the super class. It can inherit new abilities with new methods, potentially conflicting with the names of methods in your subclass, it can expose internal state that you were depending on controlling the invariants of, and various other issues.
There must be a better way!? Well there is. Enter composition. What in the world is composition? Well simply put, instead of extending a class's functionality a class simply has an instance of that class as an internal member and it delegates behaviors to it. This changes the inheritance
is-a relationship to a
has-a relationship. Let's take a look at what this could look like with our example from above:
public class InstrumentedSet<E> extends ForwardingSet<E> { @Getter private int addCount; public InstrumentedSet(Set<E> wrappedSet) { super(wrappedSet); } @Override public boolean add(E newElement) { addCount++; super.add(newElement); } @Override public boolean addAll(Collection<? extends E> newElements) { addCount += newElements.size(); return super.addAll(newElements); } } @RequiredArgsConstructor public class ForwardingSet<E> implements Set<E> { private final Set<E> set; public void clear() { set.clear(); } public boolean contains(Object o) { return set.contains(o); } public boolean isEmpty() { return set.isEmpty(); } public int size() { return set.size(); } ... repeated for every method in the Set interface. }
OK what did we just see. We took our one class using inheritance and turned it into two classes without using inheritance but using composition. What did this gain us? It helps us have more robust code. We have isolated ourselves from changes in the individual concrete classes, there is no chance of something changing out from under us because we control the whole interface, etc. We also got some more flexibility. We now take in a
Set of any type (not just
HashSet) and can operate on any of them. We can even add the instrumentation after the
Set has been initialized by some other piece of code.
The way we are using the wrapper class above is called the Decorator pattern. We are taking an already existing object and "decorating" it with additional behavior while still allowing it to be used as the original object.
So nothing is without it's downsides, what are our downsides here? Well the main one should be pretty obvious. We took a pretty small class using inheritance and ended up with two classes and a lot more mind numbing code where we just duplicating an interface as we forward on calls. While this is a good chunk of code it's not hard code to write. This is such a solid pattern that languages such as Kotlin build syntactic sugar around making this pattern easier to code up without so much code. You can also reuse these forwarding classes after you have written them. I have also always wondered if you could use Java proxies to generate these forwarding classes at runtime. Make that an exercise for the reader.
Inheritance truly does have a place. When you can truly say that
WidgetB
is-a
WidgetA then an inheritance relationship can be appropriate. If
WidgetB instead just needs to have the behavior of
WidgetA then composition is likely what you are after. Honestly, if you can get away with composition it's likely the safer bet. There is a lot of robustness and power that comes when you use this pattern and I hope you can recognize when this pattern could be useful to you as your continue along your development efforts.

Azure Storage for Serverless .NET Apps in Minutes
WebDev Tools
Azure Storage is a quick and effortless way to store data for applications that has high availability, is secure, scales and is redundant. This blog post walks through a simple application that creates a short code for a long URL to easily reference it. It uses Table Storage to map codes to URLs and a Queue to process redirect counts. Everything is handled by serverless Azure Functions. The only prerequisite to build and run locally is Visual Studio 2017 15.5 or later, including the Azure Developer workload. That will automatically install the Azure Storage Emulator you can use to program against tables, queues, blobs, and files on your local machine. You do not have to have an Azure account to run this on your machine.
Build and Test Locally with Function App Host and Azure Storage Emulator
You can download the source code for this project here.
Feel free to jump ahead to follow the step-by-step instructions, or watch me follow through this blog post in a short video:
Open Visual Studio 2017 and create a new “Azure Functions” project (the template will be under the “Cloud” category). Pick a name like,
ShortLink.
In the next dialog, choose “Azure Functions v1”, select “Http Trigger”, pick “Storage Emulator” for the Storage Account, and set Access rights to “Anonymous.”
Right-click the name
Function1.cs in the Solution Explorer and rename it to
LinkShortener.cs. Change the function name to “Set” and update the code to use “href” instead of “name” as follows:
Hit F5 to run the function locally. You should see the function console launch and provide you with a list of URLs to access your function.
Access the end point from your web browser by copying and pasting the URL for the “Set” operation. You should receive an error message asking you to pass an href. Append the following to the end of the URL:
?href=
You should see the URL echoed back to you. Stop debugging (SHIFT+F5).
Out of the box, the functions template creates a function app. The function app hosts multiple functions, which are snippets of code that can be triggered by various events. In this example, the code is triggered by an HTTP/HTTPS request. Visual Studio uses attributes to declare the function name and specify the bindings. The log is automatically passed into the method you to to write logging information.
It’s time to add storage!
Table Storage uses a partition (to segment the data) and a row key (to identify a unique data item). The app will use a special partition of “1” to store a key that indicates the next code to use. The short code is generated by a simple algorithm that translates an integer to a string of alphanumeric characters. To store a short code, the partition will be set to the first character of the code, the row key will be the short code, and a target field will contain the full URL. Create a new class file and name it
UrlKey.cs. Add this using statement:
using Microsoft.WindowsAzure.Storage.Table;
Then add the class:
Next, add a class named
UrlData.cs, include the same “using” statement and define the class like this:
Add the same using statement to the top of the
LinkShortener.cs file. Azure Functions provides special bindings that take care of connecting to various resources. Modify the
Run method to include a binding for the key and another binding that will be used to write out the URL information.
The
Table attributes represent bindings to Table Storage. Different parameters allow behaviors such as passing in existing entries or collections of entries, as well as a
CloudTable instance you can think of as the context you use to interact with a specific table. The binding logic will automatically create the table if it doesn’t exist. The key entry is automatically passed in if it exists. This is because the partition and key are included in the binding. If it doesn’t exist, it will be passed as null and you can initialize it and store it as a new entry:
Next, add the code to turn the numeric key value into an alphanumeric code, then create a new instance of the
UrlData class.
The final steps for the redirect loop involve saving the data and updating the key. The response returns the code.
Now you can test the functionality. Make sure the storage emulator is running by searching for “Storage Emulator” in your applications and clicking on it. It will send a notification when it is ready. Press F5 and paste the same URL used earlier with the query string set. If all goes well, the response should contain the initial value “BNK”. Next, open “Cloud Explorer” (View -> Cloud Explorer) and navigate to local developer storage. Expand table storage and view the two entries. Note the id for the key has been incremented:
With an entry in storage, the next step is a function that takes the short code and redirects to the full URL. The strategy is simple: check for an existing entry for the code that is passed. If it exists, redirect to the URL, otherwise redirect to a “fallback” (in this case I used my personal blog). The redirect should happen quickly, so the short code is placed on a queue for a separate function to process statistics. Simply declaring the queue with the
Queue binding is all it takes for the storage driver to create the queue and add the entry. You are passed an asynchronous collection so you may add multiple queue entries. Anything you add is automatically inserted into the queue. It’s that simple!
Run the project again, and navigate to the new “Go” endpoint and pass the “BNK” parameter. Your URL will look something like:. You should see it redirect to the page you originally passed in. Refresh your Cloud Explorer and expand the “Queues” section. There should be a new queue named “counts” with a single entry (or more if you tried the redirect multiple times).
Processing the queue ties together elements of the previous function. The function uses a queue trigger and will be called for and with each entry in the queue. The implemented logic simply looks for a matching entry in the table, increments the count, then saves it.
Run the project, and if your Storage Emulator is running, you should see a call to the queue processing function in the function app console. After it completes, refresh your Cloud Explorer. You should see the queue is now empty and the count has been updated on the URL in Table Storage.
Publish to Azure
It’s great to be able to run and debug locally, but to be useful the app should be hosted in the cloud. This step requires an Azure Account (you can get one for free). Right-click on the
ShortLink project and choose “Publish…”. Make sure “Azure Function App” and “Create New” are selected, then click the “Publish” button.
In the dialog, give the app a unique name (it must be globally unique so you may have to try a few variations). Choose “New” for the resource group and give it a logical name, then choose “New” for plan. Give the plan a name (I like to use the app name followed by “Link”), choose a region close to you and pick the “Consumption Plan” then press “OK.”
Click “Create” to create the necessary assets in Azure. Visual Studio will create the resources for you, build your application, then publish it to Azure. When everything is ready, you will see the message “Publish completed.” in the Output dialog for Build.
Test adding a link (replace “myshortlink” with your own function app name):
“ Then test the redirect:
You can use the Storage Explorer to attach to Azure and verify the count.
But wait – isn’t Azure Storage supposed to be secure? How did this just work without me entering credentials?
If you don’t specify a connection string, all storage references default to an
AzureWebJobsStorageconnection key. This is the storage account created automatically to support your function app. In your local project, the
local.settings.jsonfile points to development storage (the emulator). When the Azure Function App was created, a connection string was automatically generated for the storage account. The application settings override your local settings, so the application was able to run against the storage account without modification! If you want to connect to a different storage account (for example, if you choose to use CosmosDB for premium table storage) you can simply add a new connection string and specify it as a parameter on the bindings and triggers.
When you publish from Visual Studio, the publish dialog has a link to “Manage Application Settings…”. There, you can add your own settings including any custom connection strings you need, and it will deploy the settings securely to Azure as part of the publish process.
That’s all there is to it!
Conclusion
There is a lot more you could do with the application. For example, the application “as is” does not have any authentication, meaning anyone could access your link shortener and create short links. You want to change the access to “Function level” for the “Set” function and secure the website with an SSL certificate to prevent anonymous access. For a more complete version of the application that includes logging, monitoring, and web front end to paste links, read Build a Serverless Link Shortener Faster than you can Finish your Latte.
The intent of this post was to illustrate how easy and effective the experience of integrating Azure Storage with your application can be. There are SDKs available to perform the same functions from desktop and mobile applications as well. Perhaps the biggest benefit of leveraging storage is the low cost. I run a production link shortener that processes several hundred hits per day, and my monthly cost for both the serverless function and the storage is less than one dollar. Azure Storage is both accessible and cost effective.

Overview:
This post will go over some simple but effective ways to setup common initialization and cleanup for Unit Tests on a larger scale than [ClassInitialize] and [TestInitialize] methods can provide for.
First, to establish a common starting point I’ll go over some of the basics, if you’re already familiar with using the ClassInitialize/Cleanup and TestInitialize/Cleanup attributes in unit tests you may wish to skip this next part.
Background:
When you have some setup and cleanup code that needs to run for several unit tests typically you would put them in the same Test Class and use a combination of Class Initialize/Cleanup and Test Initialize/Cleanup methods.
A simple start would be something like this:
[TestClass] public class TestClass1 { [TestInitialize] public void TestInit() { Console.WriteLine("TestClass1.TestInit()"); } [TestMethod] public void TestMethod1() { Console.WriteLine("TestClass1.TestMethod1()"); } [TestMethod] public void TestMethod2() { Console.WriteLine("TestClass1.TestMethod2()"); } [TestCleanup] public void TestCleanup() { Console.WriteLine("TestClass1.TestCleanup()"); } }
If you run both tests here the output will be:
TestClass1.TestInit()
TestClass1.TestMethod1()
TestClass1.TestCleanup()
and
TestClass1.TestInit()
TestClass1.TestMethod2()
TestClass1.TestCleanup()
The methods marked with the attributes [TestInitialize] and [TestCleanup] run before and after each test in that class. If instead you’d like to only run the initialization code once before all tests (not each individual test) you could use [ClassInitialize] and [ClassCleanup] instead, or you can also use them in combination.
Going Beyond Local ClassInitialize and TestInitialize
What can I do if I have a large project, with dozens or even hundreds of unit test methods spread across several classes and you want to share some setup or cleanup code between those tests?
One approach would be to create some initialize and cleanup helper methods in a separate class and call those methods from each of your individual test classes initialize and cleanup methods.
Another approach, the one I personally prefer, is to create a base class for your test classes. For example:
[TestClass] public class TestBase { [TestInitialize] public void BaseTestInit() { Log.AppendLine("TestBase.BaseTestInit()"); } [TestCleanup] public void BaseTestCleanup() { Console.WriteLine(Log.ToString()); } public static StringBuilder Log { get { if (s_log == null) { s_log = new StringBuilder(); } return s_log; } } static StringBuilder s_log; } [TestClass] public class TestClass1 : TestBase { [ClassInitialize] public static void ClassInit(TestContext testContext) { Log.AppendLine("TestClass1.ClassInit()"); } [TestInitialize] public void TestInit() { Log.AppendLine("TestClass1.TestInit()"); } [TestMethod] public void TestMethod1() { Log.AppendLine("TestClass1.TestMethod1()"); } }
Notice that the base class “TestBase” is also using the [TestClass] attribute, although we won’t be putting any test methods in this class. This allows the use of the [TestInitialize] and [TestCleanup] attributes within our base class. If you ran the tests in TestClass1 you would see the following output:
TestClass1.ClassInit()
TestBase.BaseTestInit()
TestClass1.TestInit()
TestClass1.TestMethod1()
The [ClassInitialize] will always run first, it’s static and will be invoked by the unit test engine before instantiating the test class. Next we see that the Test Initializer in the base class is called, followed by the Test Initializer in the test class itself, and lastly the test method is executed.
How can I create an initialization method that will run before any class initialization methods in my test project?
Building on the common base class approach described above you could simply add a static constructor to your base class and either perform the initialization there or call the method that will perform the desired initialization. The resulting base class might look like this:
[TestClass] public class TestBase { static TestBase() { s_log = new StringBuilder(); Log.AppendLine("TestBase.ctor()"); } [TestInitialize] public void BaseTestInit() { Log.AppendLine("TestBase.BaseTestInit()"); } [TestCleanup] public void BaseTestCleanup() { Console.WriteLine(Log.ToString()); } public static StringBuilder Log { get { return s_log; } } static StringBuilder s_log; }
Will the same approach that was used for [TestInitialize] work with [ClassInitialize] in a base class?
Not exactly, if you create a [ClassInitialize] attributed method in the base class it won’t ever get called unless you explicitly call it at the beginning of your derived test classes ClassInitialize method; which of course is nowhere near as nice as the above approach.
If you really wanted this functionality you could hook the method calls using reflection and set things up that way, but that’s beyond the scope of this post.
Setting up the relationship in the reverse would be much easier, but is of questionable value. By reverse order I mean that it would be easier to create a method that resided in the base class and was called once per test class but it would be called after the derived classes ClassInitialize method.
The only viable option that I can come up for achieving an inheritable class initialization approach would be to ditch the ClassInitialize mechanism altogether and go back to good old fashioned class constructors.
Example:
[TestClass] public class TestBase { static TestBase() { s_log = new StringBuilder(); Log.AppendLine("TestBase.TestBase() <-- acts as ClassInitialize in base"); } [TestInitialize] public void BaseTestInit() { Log.AppendLine("TestBase.BaseTestInit()"); } [TestCleanup] public void BaseTestCleanup() { Console.WriteLine(Log.ToString()); } public static StringBuilder Log { get { return s_log; } } static StringBuilder s_log; }
[TestClass] public class TestClass1 : TestBase { static TestClass1() //Replaces ClassInitialize method { Log.AppendLine("TestClass1.TestClass1() <-- acts as ClassInitialize in derived"); } [TestInitialize] public void TestInit() { Log.AppendLine("TestClass1.TestInit()"); } [TestMethod] public void TestMethod1() { Log.AppendLine("TestClass1.TestMethod1()"); } [TestMethod] public void TestMethod2() { Log.AppendLine("TestClass1.TestMethod2()"); } }
Running TestMethod1 in the derived class produces the following output:<?xml:namespace prefix = o
TestBase.TestBase() <-- acts as ClassInitialize in base
TestClass1.TestClass1() <-- acts as ClassInitialize in derived
TestBase.BaseTestInit()
TestClass1.TestInit()
TestClass1.TestMethod1()
TestBase.BaseTestInit()
TestClass1.TestInit()
TestClass1.TestMethod2()
PingBack from
I don’t think that the last part of your post is accurate. MSTest creates your test fixture once for each test and hence it does not double for ClassInitialize.
TestDriven.Net DOES support inheritance of ClassInitialize but it does not support AssemblyInitialize. In addition, if you’re using MSTest you’re probably looking to it for the TFS integration so you have to make sure that works too.
Good catch George, I corrected the last part so that it works as described. The constructors should of course be static in order to work as the static ClassInitialize would.
Your approach of putting common initialization code in a base class is perfect, with one caveat. If you use the nifty new TestCategory attribute, your inherited code won't get run if you specify one or more categories, unless you give the base class its own category (i.e., "always"), and remember to always specify the "always" category.
After more research, things seem a little more complicated. TestInitialize and TestCleanup seem to work from the base class, regardless of categories, even if the base class isn't marked as a TestClass. ClassInitialize, ClassCleanup, and AssemblyInitialize, however, only seem to work from the derived class, regardless of categories, even if the base class is marked as a TestClass. This is Visual Studio 2010 SP1 targeted at .NET 4.0.
I came across something weird: I have a base class with TestClass attribute which contains the common TestInitialize and TestCleanup methods. In the derived test class, I am running a data driven test method which reads data from an XML file.
The XML file has several rows of data. When executing the test method, for the first time the TestInitialize method from the base class is called alright, the test method executes and the TestCleanup from the base class is called. Now for the second iteration the TestInitialize method of the base class is NOT called, the test method executes and the TestCleanup of the base class is called, effectively screwing up the whole testing.
Is this a common phenomena, are there any workarounds?
Good info, covers *almost* everything… How would you do the equivalent of [ClassCleanup]? I've tried finalizers but they don't seem to do what I'm expecting… | https://blogs.msdn.microsoft.com/densto/2008/05/16/using-a-base-class-for-your-unit-test-classes-2/ | CC-MAIN-2018-34 | refinedweb | 1,292 | 53.41 |

He’s gone now, dead man walking
Here is a great clip from an interview panel featuring Pachauri and the head o the California Air Resources Board (June 2008). It’s quite revealing to weigh Pachauri’s claims and his rhetoric against what has been learned in the past few months. Here’s a sample:
PACHAURI: .

Cheers,
Ken in North Dakota
And he called the Indian Scientific position arrogant?
Certainly no respect or consideration for any organization
or for anybody. Should be booted out into the alley. The
front door is too good for him.
Mr. Railway Engineer, you do know what the light at the end of your tunnel looks like?
We still have a long way to go.
It will take a lot more disclosures of lies, manipulation, frauds and debunking before the warmist’s give up as becomes clear from the following example:
While paying lip service to skeptics,
UK chief science advisor insists it is “unchallengeable”
that man is changing the climate!
Are you sure Dr Pachauri isn’t from Chicago? Sounds like Chicago politics to me.
“within three or four days, we were able to come up with a clear and a very honest and objective assessment of what had happened”
Hmm… I heard no mention of Halcrow Consulting anywhere in the ‘honest and objective assessment of what had.”

Does that look like a mistake to you?
OT- the Penn State report is late. Anyone see it?
Somehow this context reminds me of the wonderful little book, “On Bullshit.” Pachauri appears to be a consummate BS artist. I think what happens to bad BS artists is that they stop believing in their BS, and they are caught, or lose their stomach for it. And what happens to great BS artists is they believe their BS, they run too many absurd bets against reality, and eventually reality calls them on it, and they fail.
Pachauri’s bet has been called.
My own bet is, he’s gone in a month. I am torn between wanting to see him gone sooner (so he does less damage) and later (so he twists in the wind, and damages the IPCC brand with his contortions).
Hear no Evil!
A whimsical look at the Senate reaction to Obama’s claim of “the overwhelming scientific evidence for Climate Change”.
Whether he can hold on to get out AR5 is the least of Dr Pachauri’s problems. As damaged goods, who will want to hire him post-IPCC? For his influence and pull? Will those with grants want to dispense them to any activity which hires him?
I perceive that Pachauri will brass it out until the bitter end. This is actually a blessing in disguise since it will take down the IPCC as well. It will stain the UN also. But it will be hard to see that stain on such an already discolored reputation.
Pachauri keeps hanging himself. All anyone wants fron the UNIPCC is simply transparency, accountability and responsibility. When their climate claims are exaggerated, manipulated and made up then it is unlikely we will get what we want anytime soon.
At last Pachauri and company are toast?
Weird newscast.
It gave all sides of the story.
Pachuri isn’t going to stand down cause he says he’s going to stand up!?
On the 4th of December, Pachauri put out a statement that included:
.”
And:
“In summary, no individual or small group of scientists is in a position to exclude a peer-reviewed paper from an IPCC IPCC assessments comprehensive, unbiased, open to the identification of new literature, and policy relevant but not policy prescriptive.”
“No possibility” and “no ability” are emphatic statements. They are falsified by the existence of even a single contray example. So he knew that these statements were false when he issued them.
Uh oh.
.”
Damning evidence that Pachauri is corrupt — the bigger question — how many other people at the IPCC are equally corrupt and how high and far does it go?
This latest development has to be linked to Pauchauri’s comments in early November when he was challenged on the glacier issue and accused the Indian scientists/government of being arrogant and guilty of voodoo science. It would appear that when he made these serious accusations, he already knew that the IPCC report was wrong and there was no scientific evidence backing up the IPCC glacier claims. Accordingly, it would appear that at the very least he was being disengenuous, if not deceiptful in not answering honestly/truthfully the issues of doubts raised in November. This looks bad for the chairman of a supiosedly independent scientific body.
what a classic response from pachauri!
Science Mag: Extended Interview:
Climate Science Leader Rajendra K. Pachauri Confronts the Critics
Pallava Bagla
Q: Has all that has happened this winter dented the credibility of IPCC?
R.K.P.: I don’t think the credibility of the IPCC can be dented. If the IPCC wasn’t there, why would anyone be worried about climate change?
The BBC published these denials by Pachauri on Dec. 5, 2009. Article by above mentioned Bagla. They’ve been sitting out there little noticed all this time. “Himalayan Glaciers Melting Deadline a ‘Mistake’,” by Pallava Bagla in Delhi. Includes Pachauri calling India’s Environment Minister Ramesh’s findings on glaciers “voodoo science”.
Why would Pachauri feel that he could pull this on his own people?
What am I saying? Gore almost got away with it too…
Where does this put the EPA and CO2 controls?
“Oh what a tangled web we weave,
When first we practise to deceive! ”
[Sir Walter Scott]
Ken – that clip is an absolute ‘gotcha.’ Clearly, Pachauri does not feel bound by facts when a good cause is at stake. He needs to go, not only for the credibility of the IPCC, but for the credibility of science.
The reason that warmists are losing the debate is that they are not arguing on the basis of facts, but choose instead to push implausible propaganda to motivate action. It is a stupid strategy, that has now been found out.
If leading physical scientists don’t start condemning this use of spin, bullying, and half-truth, large sections of the public may lose faith in science altogether. Not just climate science, but all public science.
If the IPCC goes down, so does the EPA endangerment finding.
We will all miss Rajendra Pachauri when he’s gone.
Slicker, more polished crooks in high places hope the story will stop there.

Why does this surprise anybody, this ‘charade’ as it has been exposed?
It is drawing out now only the *thickest* of low-level trolls who are becoming as ‘thick as fur’ … gone are the days when Joel Shore, noted physicist would debate and argue actual (albeit perhaps obscure, non-essential) technical points, we now have certain ‘thickheads’ who don’t even know the basis (initially counter SM and MM), the beginnings (David Fenton communications), the reason for existence (promote _only_ the AGW viewpoint) of RC (realclimate.org)!!!!

No, but the higher-ups have selected him to inspect the undercarriage of the train they’re preparing to toss him under.
Cleansing the IPCC of Pachauri no more cleanses the IPCC than firing Phil Jones,Michael Mann, and their ilk, would cleanse the legacy of IPCC ‘science’. The entire administrative edifice of the IPCC should be discarded and replaced with nothing at all. This intergovernmental attempt at supranational administration is revealed to be a failed experiment. The IPCC, from its creation, was an agenda immune to refutation.
We seem to be forgetting that these people are career diplomats/beurocrats. As such their lives revolve around reaching agreements and consensus.
With that in mind, I contend Pachauri will neither resign nor will he be sacked. What will happen is that he will be PROMOTED within the UN, with the usual accolades and thankyous for his dedication yada yada yada. Don’t be surprised if Yves De Boer isn’t standing beside him at the press conference announcing this. Show of support wink wink

If only it were that simple. The rot goes far beyond the scientists, they are just the front lines. If we were talking about infantry, they would be called “bullet stops”. The roy will protect itself. The scientists will leave one by one, each with a severance package requiring non-disclosure of terms and issues. That protects the scientists because they legaly can’t discuss what happened and why for fear of losing their severence package. It protects the rot higher up because now no one is going to give up their severence package to let the cat out of the bag that they were just producing the results that the higher ups wanted. They’ll quietly find low profile jobs with the assistance of the political hacks they are protecting. The IPCC will get reorganized or dissolved and replaced, with the political hacks who now cannot be implicated still in charge. When a suitable time has passed they quietly resurrect their soldiers with new titles and positions and issues to manipulate the tax payer with.
I wish it were not so, but I am old enough to be cynical and to have seen history repeat itself.

Exactly! I have observed and could name members of the round robin-ed circle of peer-reviewed trust for space sciences since the early 1960s.
But I was more disturbed when the Climategate scandal exposed these scientists and the UN’s IPCC as part of an unholy international alliance of politicians, scientists, news media and publishers that have used science as a propaganda tool to try to control the world.
That is frightening! In the best of circumstances, self-governance may work if the people have reliable information.

The rot will try to protect itself; that’s what this whole thing has always been about. Depending on how this plays out, AGW could become a textbook case in how scientists can go bad. Scientists are highly egotistical and many of them do not take criticism well. Even though this is contrary to the principles of science, it is not contrary to the principles of psychology — it is typical human nature.
The whole thing is nothing more than a classic case of abuse of power by pusillanimous people.

Hello,….. Policitians, Main Stream Media, Wake up. How long are you going to have your head stuck on stupid? Parliament is not in session and you cannot learn anything while your typing drivel. Maybe spend some time on the internet and search climategate, IPCC AR4 bogus, scandals at the CRU, NASA and Penn State. You will be very surprised to learn a lot of things have happen since your went and Rip Van Winkled on us. IPCC AR4 is a fraud and all the scientists involved in this have their reputations and credibility in disrepute. You will now realize there is something important to write. Like, Why are we on the doorstep of signing legally binding legislation based on a false report. You could also ask the politicians why they Rip Van Winkled.

You gonna get back into the failed solar panel business that you had in Europe?
You could never find an “angle” to make people want to buy solar panels because they weren’t worth the money – you figured the only way to get people to buy solar panels, was to have the Government FORCE people to buy solar panels
You figured wrong, Choo Choo

These guys are in this [expletive deleted] deep, and many may stand to loose their pensions, and some churches other than the ‘Church of AGW’ may also loose their robes. It is going to be a mess. It will definitely end up in court.

Just a crazy thought for the US readers here. The US constitution requires a separation between church and state. Specifically it states the US government shall not establish a state religion.
Environmentalism in general (endangered species, zero threshold tolerance for all toxins) and anthropogenic global warming specifically (we are all going to die unless we live in mud huts again) meets all of the qualifications describing a religion. The proponents are immune to logic and prosecute their non-scientific beliefs with religious zealotry. They have insinuated themselves into government and are making their personal faith the official US national religion.
I wonder if there is a constitutional challenge or remedy to reverse this religious takeover? Otherwise these religious environmental mullahs will ruin this country.
Fraudulent science was used to buttress the AGW premise and it was found out thanks to WUWT and others. I wonder how much fraudulent science is being used to stand-up the other enviro-green arguments. I think it may be a rich mother-lode for others to mine. These may be easier to topple than AGW was.
We never voted for these religious environmental mullahs. We never had a choice.

Your post immediatley above is very moving and inspirational! I think all of us here are very conscious that we are witnessing – partaking in – a very important moment in the human story.
I can’t contribute to the science but I’m doing my best instead to disseminate the facts and to bring this site and a couple of others inc CA to the attention of as many people as possible, so to assist the collective effort in another way.
Thank you Anthony for having persevered, and for providing this extraordinary ‘environment’ in which the truth can seed, grow, and take wings. I don’t have children, but those who do will be forever in debt to you and those like you who’ve fought the good fight.

Someone above asked where Al Gore is. I wondered, too, because I thought maybe he finally found some dignity somewhere to stop this nonsense. But no!
He’s busy right this moment pushing this climate hysteria as religion. See my post and click links (the religion post on his site is dated 1/22/10). Gore – with Yale University, of all places, and churches – is desperately working to indoctrinate people, complete with prayer, in climate change.
I think everyone probably already knows about his company Silver Springs, which will provide software and meters to monitor our carbon usage.
Not only is that Orwellian and creepy, but he’s going to make millions, billions… No wonder he’s cramming this crap through as religion. He wants his damn money and he wants it now!.
One last thought, why can a person – like I heard on the news the other day – go away to prison for stealing a trench coat, but Gore is involved in deceiving everyone on the planet for his own gain – yet he’s not locked up?
What if Pachuri is only a front man — for bigger fish pulling the strings…
And now that AGW is crashing down — he’s the designated fall guy — not that he isn’t guilty, mind you, just that he isn’t alone…
As of my writing foxnews.com is now carrying this story on top of their home page, left column.
The headline in the graphic that has a photo of Mr. P. sez:
”Before Copenhagen, Climate Chief…
KNEW OF ERRORS”.
When you click on the photo at foxnews, the underlying piece links to the same Times Online article as this thread start.
AND:
If you click on the foxnews link UNDER the graphic that sez:
”U.N.’s Global Warming Report Under Fresh Attack for Rainforest Claims”,
they have a piece that is IMO a good summary of Amazon-Gate.
Attaboy, FoxNews. . . . :-]
CNN ?? . . . Nowhere that I can see. . . .
Someone floated the idea on another blog yesterday that Pachauri had been put in place by the Bush admin with the express purpose of discrediting AGW/climate change and bringing the whole shebang into disrepute, but I find that a little farfetched esp as they might well have got away with the scam without CRU/Climategate.
But in the Alice in Wonderland world of climate change, who can rule out any scenario?.
Clear voodoo chairmanship…..Pachauri now a zombie!
Andrew30 (18:07:17) :
Damn good points Andrew….. Pachauri’s goose is cooked. That’s ironic considering he’s a vegetarian an’ all;-)

jaymam (23:16:34) : “He should believe in ‘global warming’ since that is happening, slightly”
Apart from the fact that “believe in” is an inappropriate terminology in this context… doesn’t the truth of “global warming is happening” depend on the time scale you are referring to, and the integrity and accuracy and adequacy (all of which are questionable at this stage of our knowledge) of the data you base your opinion on?
Andrew30 above discusses the Institutional Investors Group on Climate Change (IIGCC), which “represents assets of around €4trillion” and includes a whopping number of prominenten in the U.K., both social and governmental.
I’ve got to figure that there are similar critters, institutions, and aggregates who are stuck deeply into this same humongous fiscal Tar Baby in these United States, and there are foxes and bears a-plenty slavering to rend their flesh.
One of the principles of economics is that malinvestments must be liquidated. The financial slight-of-hand types who inflated the residential housing bubble in America and made it “the way to promotion and pay” had long known that it was soon coming to a pop, and obviously they’d been manipulating the “global warming” fraud as a vehicle through which they could fasten their fangs at another point upon the body politic’s jugular vein.
Those who took their counsel and followed these “master of back-stabbing, cork-screwing, and dirty dealing” types into positions in this castle-in-the-clouds environment are now hearing the gurgle-gurgle of flowing currency circling the drain.
Look forward to another “stimulus package” from Barry Soetoro and his little ACORN elves as the politically connected swashbucklers on Wall Street squeal (again) for rescue.
Where are Joel Shore and Scott Mania when we need them? They made a high quality counter point to the rest of us-including me-singing from the same song sheet.
Are they embarassed at the recent deluge of information which seems to point out their position was based on incorrect information? Or did they merely become exasperated at being the lone voices. Debate is good. Come back Joel and Scott-all is forgiven.

davidmhoffer (19:45:25) :
erm, yes. I think that’s what happened to the excellent German scientists after WWII. Reformed into NASA or the like. And your spelling was not a mistake. “Roy” means “royalty” after all :)
Each one of them will stay completely incapable to admit an error until they’re thrown under the bus. Ignorance was their recipe to success, ignorance will bring them down.
Loot at Gore. He learned that when you don’t know the answer to a question, just invent one that suits your needs and try to get away with it. Asked about the temperature of the earth’s core, he hesitates, then laughs nervously and says millions of degrees. Pachauri is exactly like that.
They make their answers up as they go. Pachauri, Gore and the entirety of The Team make up their answers as they go. It’s an entire culture of con artists.
Climate sceptics bask in warmth of bad news.

…look at this explanation by Vicky Pope about how the long term projections by the Met Office are made and how reliable they are. Start watching at 0:55. She says they made 400 models, “representing all that we know about the uncertainty of the science in our models”.
Wait. They can cover all parameter permutations of the things they don’t know and thus have to parameterize to run a model at all with 400 runs? No.
Again, this is making up an answer and trying to get away with it, a bald faced lie. They made 400 models because that was the maximum number they could run in the timeframe given. The entire philosophy of climate “science” is: when we can deceive 85% of the population, that’s more than enough in a democracy. It’s not even an attempt at believable propaganda. It’s incompetence and confidence tricks wherever you look.
Chili palmer (18:52:49)
I notice NOW the BBC report of Dec. 5. 2009 that you have highlighted was inconspicuously hidden away in the South Asia section of the BBC site, not exactly somewhere I would normally read, very convenient if the BBC didn’t want to rock the boat 2 days before Copenhagen.
Well worth the read thanks.
Something that should not be overlooked here, with regard to the bigger picture, is that this is yet another ‘sceptical’ article in the London Times. The two left-leaning UK papers, The Guardian and the Independent will never express scepticism over AGW because to them Man-made Global Warming is short for Western Capitalist Man-made Global Warming and to question that would be to question their whole raison d’être.
However, the centre/right-wing press is becoming much more outspoken (and, if you ever read the comments on an AGW article in them, with justification if they want to keep their readership).
What with the Climategate enquiry, the Parliamentary investigation, the Lawson think-tank being set up, and the upcoming election, amongst other things, it does look like the UK is going to be the major battleground over AGW in the coming months. The ongoing very cold winter is also helping the sceptics’ cause. At the moment, the momentum is all with the sceptical side thankfully.
I agree with I once said on WUWT that Pachauri should resign. I have since then changed my mind because I think he has become our best ally. :o)
I agree. It’s Machiavellian, but the longer Pachauri and his followers try to defend the IPCC the more opportunities there will be to get the media on our side and expose the IPCC’s political agenda and corrupted science (and the problems with CRU, GISS and USHCN etc.). The reality is that while we are winning the scientific arguments, the media are only just beginning to take an interest , and there are still many people and politicians who are convinced the planet is heading for catastrophic warming as a result of our CO2 emissions, who will not willingly divest their personal and financial commitments to AGW. Much depends on the course taken by the mainstream media; will they let their love of scare stories (like the Himalayan glaciers disappearing by 2035 – which perfectly demonstrates their scientific illiteracy and gullibilty) get in the way of proper investigation of what is arguably the largest scientific scandal in history? Having seen how the MSM failed to question or take any interest in the many holes in the offical 9/11story, and then lapped up the illegal war in Iraq, I am not too optimistic that we can rely on them too much. The BBC had the bones of the glaciergate story on December 5th – but buried it on the south-asia section of their website. Likewise the CRU emails and code, which they sat on for weeks, and then, even after it went viral on the web, they chose to ignore and play down, apart from an odd 5 minute report on Newsnight. It seems that Andrew Neil and Stephen Sackur are the journalists in the BBC with any credibilty. This is going to be a long battle, and I fear it may well take a few more long cold winters in the NH to get the idiots in Washington, NYC, London and Berlin to see the light. Looking at the geo-politics of AGW, there is no way that the Russians and Chinese will go along with significant CO2 emission reductions, as their economies are too dependent on fossil fuels and economic development. The question is whether they will be happy to watch the west waste money and resources on pointless AGW mitigation policies. In the cold war, this would have been the obvious course of action for them. But now with a global economy, and so much Chinese investment in the USA (and UK), they will hopefully want to see some return (or at least get the interest payments back), which is much more likely if we have functioning economies, where we burn coal and oil for heat and energy, rather than fanny about trying to capture the CO2 in it. So the Chinese and Russians are going to be key players (and allies) in the political battle to overthrow the AGW alarmists. (And I have no problem with that, the planet’s too small for us all not work together).
Sorry, that was meant to be a short comment, but its Saturday morning and freezing outisde.

The BBC needs putting out to grass – or perhaps putting down. It is past its sell-by date.

The Times link is incomplete, here is the full one:
Pachauri already has his next career move sorted. He is going to be a writer of fiction and his first book is already out. Easy transition. It amazes me how one man can be on so many dfferent boards and panels, he must have written this whilst flying around the world to save the planet.
In his own words:
“The major financial scandal that one of the largest IT companies in India, Satyam Computer Services Limited, has been involved in has shaken the confidence of the public, of the government and the corporate sector in general across India. Given the size and scale of this major fraud, there would also be several organizations across the world that would also be affected profoundly by this development particularly those that have had dealings with Satyam.
Cases of corporate misdemeanor and fraudulent and unethical acts by top management appear to have become widespread in recent years, and this at a time when the social, environmental and governance challenges facing human society require a high sense of corporate social responsibility and ethics in corporate organizations!

vibenna (18:55:38) :
“If leading physical scientists don’t start condemning this use of spin, bullying, and half-truth, large sections of the public may lose faith in science altogether. Not just climate science, but all public science.”
It appears that the era of men and woman with integrity has passed. Science, money and politics are so interconnected; it is actually – Politics – money – science. “Here are the answers, here’s the money – find us the questions.” Loose faith! – It would take a reformation complete with “the inquisition” (not quite – but close) to restore mine.

This was written before Copenhagen:

Richard North is doing a superb job in exposing Pachuari and the IPCC for what they are.
He should be Knighted for ‘services to realism”.
Thank you Richard. Please keep up the great work.
I clicked on the Speakers Bureau ad just for fun. Pachauri is top of the environment list here, some other noteworthy names there as well, including Crispin Tickell, Maurice Strong and intrepid explorer Penn Hadow:

You can hire Al Gore here:
” James F. Evans (22:49:43) :

In German the saying goes: ‘The fish starts to stink at the head’.
So you would have to wonder what body part Pachauri is. And who is the head.
DirkH (01:55:53) :
.
The BBC’s website is so extensive that unless a story is linked from the front page or a regional front page, or for example the Science/Environment section, it is effectively hidden. I came across the BBC’s Himalaya Glacier pages – Himalayan glaciers’ ‘mixed picture’ (December 1st)
and then:
(Himalayan glaciers melting deadline ‘a mistake’ Dec 5th)
back in December, totally by accident, while looking for something else. And I suspect that both the pages were put on by the South-Asia editor, without approval from the BBC’s Politbureau / ‘Policy Unit’ in London. They certainly weren’t picked up by any UK BBC staff anyway.
Right, must go out, the sun has now finally risen over the distillery roof, so it might just be above freezing.
Money laundering the Russian way?
If you want to broaden the scope a little, try these emails. They are only part quoted and there is a chance that I have missed some continuity; but it sure looks fishy to me. (Some email parts have been deleted for brevity, without changing the meaning)

and I give you a receipt.
Rashit will go to Yamal at the end of June and I go to the Polar

From Richard North’s site I noticed this dated 29th Jan so I await the full report with interest
Mpaul@634,
of course what the guy is saying is absolutely correct, no one scientist or group can keep peer reviewed papers out of the IPCC. However what the moron has side stepped is the very fact that individual scientists and groups HAVE conspired to keep papers that go against Mann made global warming ™ from being peer reviewed in scientific publications and to keep those papers from being published, which in effect means they can be ignored by the IPCC.
Unless of course that paper is from the wwf et al.

I made a funny spoof trailer starring Pachauri as the Wolfman of Copenhagen, must watch and rate! Enjoy!
“The chairman of the leading climate change watchdog was informed that claims about melting Himalayan glaciers were false before the Copenhagen summit…”
I suspect that Pachauri knew long before Dec 09.
OT, but here in Australia, the media are on an all-out scare campaign. Stranded walruses a scare website is and it appears to be in German, ice meting, the same old adverst on TV with black carbon balLOONs escaping up into the sky etc.
And in February, the Govn’t tries to sell an ETS to the Senate.

from pat(18:49:17)
Quote from Pachauri
“If the IPCC wasn’t there, why would anyone be worried about climate change?”
Indeed, why would they?
When did Pachauri Know?
We know he knew in Dec ‘09, but he first said he knew in January ‘10.
However when he knew we knew he knew in Dec ’09, he said he did know but he was too busy. I reckon he knew before we knew he knew but he knows that we don’t know that for sure!

Yup – it’s got to be 5 stars.

I keep thinking about the old myth about how foxes rid themselves of fleas by grabbing some wool in their mouth and backing in to water until all the fleas are on the wool, and they let go of the wool.
If you think of the IPCC as the fox, Pechauri as the wool and the fleas as inconvenient truths and criticism….
The pseudo-science is settled, the only remaining problem is reality.

In view of what has happened, perhaps that should have been “Kalashnikov”.

The Nationalpost is not quite mainstream, but they are one of only two national papers in Canada. That said, the writer is full time with the CBC (Canada’s version of the BBC for you Brits). The CBC hasn’t been alarmist per se in mu opinion, but they have certainly been warmist. One of their own speaking out is sgnificant.
Unfortunately, the “real culprits” of AGW are not the Pachauri’s and Lal’s, the Phil Jones’ or the Michael Mann’s, or the millions and millions duped into demonstrating and chanting for, and donating to, “the cause”. The worst among us are the business men and politicians who used “science” and fear and sought to seperate us from our meager savings and basic freedoms for their own perverse gain. Presidents, Vice Presidents, and Prime Ministers, Senators and Representatives, MP’s, Banking and Industrial Tycoons, Publishers and Political Party bosses, these privilaged few are the true scum of the Earth. Who will hold them to account? John and Mary Voter won’t!

“Negating “Climategate”: “…” Climate Science Survive Stolen E-Mail Controversy (Read Comments)
Scientific American ^ | Jan 29, 2010 | David Biello

It’s never the lie that get you – it’s the cover-up.
Although Pachauri of TERI (Trick Every Reasonable Individual) and Jones of CRU (Crooked Research Unit) can squeal and bleat they have done nothing wrong, it is fast becoming apparent that only career politicians and the gullible are prepared to believe them anymore.
The bottom line is we have to go back to basics – back to the basic data of many thousands of temperature sites – and have sceptics and alarmists both agree how the readings from each one of these sites should be adjusted/’homogenised’ to reflect reality. This is a truly huge task as all the CRU manipulated data is now so corrupted/manipulated as to be effectively useless.
The next task is to have a well-funded independent scientific commission of independents, advised by both sceptics and alarmists, scientifically prove the warming impact, if any, of each of the various ‘greenhouse gases’ and then determine whether or not natural cycles, ‘greenhouse gases’, or a mixture of both is responsible for the very modest warming trend (~0.7 degrees C) of the past century.
This unfortunately would be impossible for many reasons, but most importantly as it would remove much of the reason for the existence of the many deeply flawed greenie and quasi-government funded climate organisations – no more snouts in the grants trough would not be an acceptable option for the self-appointed leaders of the alarmists.
Pachauri obviously needs to go – but he is only a small part of the issue. We have in place multiple individuals who are wedded to an activist environmentalist agenda. Taking out Pachauri will be useful only insofar as it leads to changes in the way lead authors are chosen and the original review and summary criteria for the IPCC are adhered to.

Just for the record, the WWF did delete my comments when i wanted to soothe them about the fate of the polar bear, pointing out that its numbers are up. One moment my post was up, the next it was gone without a trace. Maybe they don’t want their visitors to be informed? Wonder why?
Lal now claims he was misquoted. He’ll be able to brazen it out unless the reporter taped him. Or if an IPCC insider or (preferably) two comes out with accounts of routine internal suppression of awkward corrections.
OTOH, if the reporter has got him taped, then Lal will be done for. (It’s the cover-up that sinks you, not the crime.)

Pachauri, Lal, Jones, Mann (et al) are mortally wounded has beens. Gut shot banditos. It really doesn’t matter if they stay on where they are at or not, their organizations are also dying a slow uncureable death. It’s a vicious form of organizational cancer.
Not seen this linked to yet, so here goes.
An apparently rational report about research that may imply a negative feedback via H2O, with the Guardian apparently reporting it a non-hysterical manner.
Susan Solomon, of the US National Oceanic and Atmospheric Administration, says something that deserves an award if true:
“What I will say, is that this [new study] shows there are climate scientists round the world who are trying very hard to understand and to explain to people openly and honestly what has happened over the last decade.”
Turns out Obama et al in the White House have included about$700 Billion in Cap & Trade revenues in their budget projections.
As the IPCC fraud unravels, as Barry’s political bank account goes into over draft, it is very, very unlikely the Dumbocrats can scam or bribe Cap & Trade legislation into ka=law.
So the Obama administration will be looking at an additional deficit load equal to the “lost” revenue . . . should put the USA over the $2 TRILLION annual deficit.
That should make Americans want to support CO2 reductions.

Not to mention the extra millimeters of extension to the nose due to thermal expansion from Mann made Global Warming and his Hockey Stick.
Jaymam,
Sorry to shake your cage – but YES! our kids are being fed this (explative deleted) and have been for years in science class. They believe their teachers, and the teachers believe what they’re teaching because Al Gore, a former Vice President, The EPA, the Federal Government, and etc. tell them so. Textbooks agree, and many teach the textbooks without critical review. Take a look at television – buy energy efficient appliances – not because it will save you money, but it will prevent three polar bears from drowning…
End of rant…
Satisfaction at seeing some people caught up in their own game, or overwhelmed by a desire to be important is one thing, but getting education into line will be the biggest problem.

Why do these political pundits think that Pachauri will resign? They must be confusing him with someone who gives a damn.
Why do they think he will be pushed? They must be confusing the IPCC with a democratic institution, accountable to the people they serve.
These political pundits are normally right on the button when they comment on democratically elected representatives, but they are applying one measure to gauge something different. And yet, the longer he clings on, the more disrepute he will bring down upon the whole rotten edifice.
Ron de Haan,
Glad to see you got your email sorted!
I agree with your post, that too much emphasis has been given to the one confirmed illegality – FOIA violations. There are obviously more angles to this work in progress than that. Your link focuses on fraud, quite rightly. There is also the additional factor of conspiracy – clearly evidenced in the emails. Conspiracy to commit crimes is outside the summary justice act and not bound by the statute of limitations. I would have thought, at the very least, there is evidence of conspiracy to violate FOIA laws.
“While paying lip service to skeptics, UK chief science advisor insists it is “unchallengeable” that man is changing the climate!”
Well, it is. How *much* we are changing the climate, whether one means globally or locally, whether one means changing temperature or rainfall or snowfall, whether one means changing averages or distribution, and whether said changes are good, bad, indifferent or catastrophic, that of course is another matter completely!
Trouble is, what people hear when you say “man is changing the climate” is “man is causing catastrophic global warming” – but they’re not the same statement at all! Trick is to know both what he meant and what he was trying to imply…
@ Baa Humbug (07:00:54) :
So Toyota sent TERI $80,000 and got $1.5 million back? Seems like the best return any investor in TERI is ever going to see.
BTW, can someone explain how the self-described full-time salaried TERI employee Pachauri could so busy setting up Copenhagen? Did he take vacation, go on sabbatical? Or is TERI simply paying at least one person to produce and promote reports that help it bring in customers and funds?
Conflict of interest? Of course not, no one’s self-interest was conflicted.

An excellent summation of history. Unfortunately the priesthood/chiefs have recently learned to remain hidden and work through puppets like Al Gore, Maurice Strong and Pachauri. In this way they avoid being lynched by the angry masses when they people realize they have been robbed. All they have to do is move onto the next scheme with new puppets and the masses never figure out who was actually behind their fleecing.
As a female I resent the politically correct terms since I consider myself part of “mankind” Politically correct terms are just another device used in the “lets you and he fight” game fostered by the priesthood/chiefs to control the masses.

What kind do you think the schools are cramming down the kids throats? Come on! Where have you been? Gore’s still brainwashing young minds with his “humans are evil and causing global peril” crap for years. Political activism has allowed this to be in the curriculum. Kids can’t don’t know math, proper English, how to think critically (ie being spoon-fed what the Unions, activists, politicians believe).
Teachers should be published?
You don’t have kids, do you? This is all mandated testing now. ALL teachers would need to be “published”. Teachers don’t have freedom to pick and choose in these mandated tests – they have no choice in the testing these days.
Beside your foggy understanding of today’s public schools, you have an odd idea of how science should be taught: “belief” in politicized propaganda.

I hope she has the wherewithal to take the school to court on this if needed. Feeding propaganda/religion to a child in school is sickening. If Al Gore is now pushing AGW as a religion she may have a real good case. Hope it turns into another nail in the coffin of AGW.

After reading an earlier post on “Glaciergate” I decided to check up the other Murari Lal references used in the IPCC AR4 WGII report. One that I found interesting is “Lal, 2003″ – “Global climate change: India’s monsoon and its variability. Jour-
nal of Environmental Studies and Policy”. What’s interresting is that the journal is published by TATA Energy Research Institute (TERI) where Pachauri himself is a Director General
One example where it’s referenced (Page 476): “Frequency of monsoon depressions and cyclones formation in Bay of Bengal and Arabian Sea on the decline since 1970 but intensity is increasing causing severe floods in terms of damages to life and property Lal, 2001, 2003″
From the first reference () you can find that frequency of monsoons has indeed declined but to say that it’s intensity HAS increased is quite a stretch. Lal assumes in the report – from model simulations saying sea surface temperature WILL increase – that so WILL the intensity of monsoons. Notice the change of tense. No measurements to verify that is mentioned in the report.
Now I’m looking for help from English reader on the other reference to verify what’s actually sad in that one. It seems to be available in the British Library.
Are we looking at an monsoongate here?
Has this been posted before?

Java programmers have become familiar with the online Java API documentation, available from Sun and mirrored elsewhere [8]. This professional looking style of code documentation is created semi-automatically from commented source code by the javadoc tool, which comes standard with the Java Software Development Kit (SDK). Java programmers already use javac and java to create and execute programs, now it's time to add the API Document Generator to your toolbox.
Javadoc facilitates good software engineering by allowing programmers to work concurrently on different parts of a system. The object relationships specified by class interfaces can all be defined in the Javadoc generated HTML API documentation. Good API documentation allows programmers to access documentation for every component within a software system. Even if these components are still being coded, the engineer can use knowledge of their interfaces to write tighter, more integrated code.
Maintenance is not a problem for an API made with Javadoc. Interfaces and method signatures can be kept constant as code is modified. The HTML documentation may be optionally updated to reflect or at least mention changes in the implementation; but that is not necessary.
Programmers write Javadoc comment blocks within the source code of a program. Javadoc parses the raw source code files looking for Javadoc comment blocks and constructs indexed documentation from them. Javadoc creates a page for each class, with a method overview section and more detailed description section for each method. The first sentence of any method description comment is included in the method overview section, with the complete text of the comment to be found in the detailed description section.
Although Javadoc ignores code implementation of constructors and methods, it does rely on javac to compile the declarations, i.e. the class and interface definitions as well as the method signatures. If no default constructor is defined, Javadoc will include it because the compiler indicates the default Object constructor is inherited by your class [10].
Javadoc works just as well on an abstract class as it does on a class definition that may be instantiated into objects. It makes no difference to the compiler run by Javadoc whether you have implemented your code fully. In this way Javadoc supports documentation and coding in any order.
Javadoc assembles hierarchical relationships between packages, interfaces, and classes, creating HTML pages from a standard style sheet (.css file) if none is specified. For more information on style sheets, refer to a very good introduction from CNET [1].
Java supports two styles of explicit comments. The first style is the traditional C comment, where characters between the start comment mark /* and the end comment mark */ are considered a comment and ignored by the compiler.
results.print(System.out); /* Send answers to standard output. */ problems.print(System.err); /* Send errors to error channel. */
The second type of comment comes from C++, where characters between the start comment mark // and the end of that line are ignored by the compiler and considered a comment [2].
results.print(System.out); //Send answers to standard output. problems.print(System.err); //Send errors to error channel.Often it is quite useful to have a comment block, which spans many lines of code. In this case you can make your many line comment from C or C++ style comments. Have a look at the following code that demonstrates both techniques.
/* Here we print the answer of the computer's joke: hard calculations of the meaning of life, etc. */ int ultimateAnswer = 42; System.out.println ("The ultimate answer: " + ultimateAnswer); System.out.println ("\nSorry, we were just kidding there."); // Is the computer really sorry for System.out.println ("Some computers have ego problems and"); // its mistake? I think if it was it System.out.println ("have a rather loose grip on reality."); // should make us cookies or something.
Understand that the above examples should not to be included in your code. Their emphasis is on the format of the comments rather than their content. While we're on that subject...
System.out.println(firstString); /* Print two strings System.out.println(otherString); to standard output. */Only the first of the intended two commands will actually be executed. You see the problem, right? Our programmer accidentally wrapped the comment block around his or her second command. A C++ style comment block would have been much more appropriate.
Generally, an even marginally useful code comment is better than none at all, but there are always extreme cases that are exceptions to the rule. The following are two great examples of how not to comment your code.
studentCounter++; // increment the variable that counts the studentsUnless the person reading the code has a bare minimum of programming experience, the comment on this line accomplishes nothing by over explaining simple syntax. Assume someone reading your comments knows the language.
maximum = (number1 >number2) ? index1 : index2; /* choose one */This second horrible comment is more ambiguous than the statement itself, just making things worse.
Brian W. Kernighan and Rob Pike have some excellent suggestions for writing comments. They are said best as they appear in "The Practice of Programming," [3]:
i++has incremented
i.

See the java output. Notice especially that HTML was included for a default constructor (NOTE: none of the links on that page work!). This is a result of Javadoc invoking part of javac.
You can use most standard HTML tags within your Javadoc comment blocks. Javadoc can understand and include standard HTML, it generates Web pages after all. Still, keep in mind that it's not a good idea to use tags like <h2></h2> in your comments. Javadoc will include them, but your browser may become confused when it tries to display the resulting pages because Javadoc inserts it own headings and yours will interfere with them.
The above example code also shows the most common Javadoc tags and where you are most likely to use them. The following table summarizes these Javadoc tags. For more information about the Javadoc tags, see the Javadoc Home Page [10], Javasoft's page of style suggestions for commenting code with Javadoc [5], or Sun Microsystems' How To Write Comments for Javadoc [8].
c:\programs> javadoc org.acm.crossroads MySimpleProgram.javaThis command will generate and link HTML documentation for the classes found in the package org.acm.crossroads and in the source code file MySimpleProgram.java. Package names and source code file names may be given to Javadoc in any order.
You may notice that the standard Java API documentation is nicely
linked together. That is, where one class takes a String as a
parameter, a link appears so someone browsing the documentation can
follow to learn more about that class. Unless you tell Javadoc to link
your HTML documentation to the standard Java API, your pages will have
no links, just parameters listed as
java.lang.String.
Your classes probably rely heavily on the standard Java API or some
others, so to link documentation together do the following (when
invoking javadoc, keep the entire command on one line, for
readability this line is split):
c:\programs> javadocYou can link to Javadoc API posted anywhere on the Web. For example, if you have other API posted on your personal site, you can link your newest production by simply giving Javadoc the URL of your existing documentation. You can also link to HTML pages on disk, but the local links Javadoc creates for you may become dead if you later post your documentation to the Web.
-link
-link
org.acm.crossroads MySimpleProgram.java
There is also a
sourcepath option available to the
command line, which tells Javadoc where to look for the Java source
code files it should parse to create the documentation. The Javadoc sourcepath
default is the current command line directory, which is used as the base for
all class and package source code files. Using the
sourcepath option overrides the default.
It is worth mentioning that there is a bug in the Javadoc tool that prevents @see tags from linking properly. The text appears, but is not referenced properly or linked anywhere. The bug is discussed in more detail on Sun's pages of documentation for the tool [9]. In the example above, what should have been a link to the Integer class of the Java API Specification shows up as a plain text java.lang.Integer. The tool version 1.2 did indicate a problem by warning me it could not find that class.
As mentioned above, Javadoc works by calling
javac on the
source code files. If your code is not in proper Java syntax you will
not be able to use Javadoc.
Javadoc 1.3 includes the capability of further customizing the appearance of your automatically generated documentation. Up to this point we have only mentioned or worked with the standard doclet, the only style of Web page available to us for automatic generation. By creating your own set of classes that will parse Java source code and create HTML documentation, you can override the standard doclet and exercise more control over how your API documentation will look. For more information about this process, see the Doclet Overview provided by Sun [6].
This article discussed Javadoc, a powerful tool for easily creating professional looking documentation. Hopefully, this article helped you to realize the usefulness of Javadoc and will provide guidance for your upcoming projects.

Tutorial
Nidhi Shah | Published March 5, 2019
CloudContainersDevOpsObject Storage
ASP.NET Core is a cross-platform, open source framework that builds modern applications by using the C# programming language.
Kubernetes is an open source system for automating deployment, scaling, and management of containerized applications. Kubernetes is an open source project, which can run in many different environments: from laptops to high-availability multi-node clusters, from public clouds to on-premise deployments, from virtual machines to bare metal.
In this tutorial, you will learn to deploy a simple ASP.NET Core app to Kubernetes. The main purpose of this tutorial is for you to turn your code into a replicated application that’s running on Kubernetes. You can take any application that you developed on your machine, turn it into a Docker container image, and then run that image on the IBM Cloud Kubernetes Service (IKS)..
Deploying Kubernetes is definitely worth it in cases where you need to:
The IBM Cloud Kubernetes Service provides a native Kubernetes experience that is secure and easy to use. The service removes the distractions that are related to managing your clusters and extends the power of your apps with IBM Watson™ and other cloud services by binding them with Kubernetes secrets. It applies pervasive security intelligence to your entire DevOps pipeline by automatically scanning images for vulnerabilities and malware.
The goal of this tutorial for you is to turn your code into a replicated application that runs on Kubernetes. You can take the code that you developed on your machine, turn it into a Docker container image, and then run that image on the IBM Cloud Kubernetes Service. The IBM Cloud: Getting started tutorial for ASP.NET Core App is used as an example application in this tutorial.
The IBM Cloud: Getting started tutorial for ASP.NET Core App uses this sample application to provide you with a sample workflow for working with any .NET Core app on IBM Cloud™ you set up a development environment, deploy an app locally and on IBM Cloud, and integrate an IBM Cloud database service in your app. The application uses a Cloudant® noSQL DB service from IBM Cloud to add information to a database and then return information from a database to the UI.
This gif contains a title that welcomes the user, prompts the user to enter a name, and then lists the database contents with the names Joe, Jane, and Bob. The user enters “Mary” and the screen refreshes to display, “Hello, Mary, I’ve added you to the database. The database contents listed are now Mary, Joe, Jane, and Bob.”
Upon completion of this tutorial, you will know how to:
You’ll need following installed on your machine.
git clone
This step is to verify whether your app is running successfully locally before deployment. You can start by verifying the version of dotnet as follows:
dotnet --version
Next, navigate to your App folder.
cd get-started-aspnet-core/src/GetStartedDotnet
Restore the app with the following command:
dotnet restore
This uses NuGet to restore dependencies and project-specific tools that are specified in the project file. By default, the restoration of dependencies and tools are executed in parallel. For more info visit Docs.
Now, run your application with the following command:
dotnet run
The application starts listening on port 5000. You will see the following message.
5000
...
Now listening on:
Application started. Press Ctrl+C to shut down.
To pack the application and its dependencies, create a new folder named publish for deployment to a hosting system for execution. We have to use dotnet to publish. Then it’s ready to run anywhere.
publish for deployment
Publish the app to get a self-contained DLL using the dotnet publish command.
dotnet publish
dotnet publish -c Release
Running publish displays some messages with a successfully published DLL at the end of the process.
For our example, you can see the following message.
publish
...
Once the application is ready, we can make an image of it and put it inside a container. We need a file that contains step-by-step instructions to deploy the image inside the container to run our application anywhere. This Dockerfile is a basic file and you may only require a few lines to get started with your own image.
Go to the app folder (here GetStartedDotnet) and create a Dockerfile to define the Docker image.
Add the contents of Dockerfile by using your favorite editor (vim, nano, etc.) and save the file.
vi Dockerfile
FROM microsoft/aspnetcore:2.0
WORKDIR /app1
COPY ./bin/Release/netcoreapp2.0/publish .
ENTRYPOINT ["dotnet", "GetStartedDotnet.dll"]
The first line we added FROM microsoft/aspnetcore:2.0 will download the aspnetcore image from the hub repository, so it actually contains the .NET Core and you don’t need to put it inside the image. You can find more repositories and versions in the Docker hub.
FROM microsoft/aspnetcore:2.0
aspnetcore
The Dockerfile line WORKDIR /app sets our working directory in the app folder, which is inside the container that we’re building.
WORKDIR /app
Now we need to copy the contents of the publish folder into the app folder on the image COPY ./bin/Release/netcoreapp2.0/publish.
COPY ./bin/Release/netcoreapp2.0/publish
Note: You can find this path in the output when you run dotnet publish -c Release.
dotnet publish -c Release
The last line in the Dockerfile is the ENTRYPOINT statement: ENTRYPOINT ["dotnet", "GetStartedDotnet.dll"]. This line tells Docker that it should run the dotnet command with GetStartedDotnet.dll as parameter.
ENTRYPOINT
ENTRYPOINT ["dotnet", "GetStartedDotnet.dll"]
You can test your dockerized app by following the steps below. This section is optional for this tutorial, though.
First, build an image.
docker build -t get-started-aspnet
Note: You can choose any name for your app.
Running the build command displays the following message in the end.
...
Successfully tagged get-started-aspnet:latest
The following command will run an app.
docker run -d -p 8080:80 --name app get-started-aspnet
Navigate to to access your app in a web browser.
Clean up with the following commands.
docker stop /app
docker rm /app
These above commands stop and remove the Docker container of your app, respectively. You can use them to remove your container if you no longer need it.
We are now ready to create our Kubernetes cluster.
Make sure you are logged into your IBM Cloud account by using:
ibmcloud login
or
ibmcloud login --sso
Create the IKS cluster for deployment.
i. Create a Kubernetes cluster by choosing Cluster Type – Free. Give a unique name to the cluster and click Create Cluster.
Note: For more details, see Creating a Kubernetes cluster in IBM Cloud.
ii. It will take some time. It is ready to use if you see the following:
It’s time to deploy your containerized application to the Kubernetes cluster. From now on, you’ll use the kubectl command line.
kubectl
On running the kubectl get nodes command, you should see something like the following.
kubectl get nodes
NAME STATUS AGE VERSION
10.76.197.43 Ready 1d v1.10.8+IKS
Our example application uses the Cloudant database to save the data that was entered. The goal here is to show how the database is created and can be deployed to the IKS cluster. You can use any database for this purpose and follow the same steps of deployment that are mentioned here (or avoid these steps if your application does not use database at all).
To create an IBM Cloud Cloudant Database, create a new Cloudant database instance. Select Use both legacy credentials and IAM under Available authentication methods.
Create new credentials under Service Credentials and copy the value of the url field. (See image below).
Create a Kubernetes secret with your Cloudant credentials.. For more info, visit Kubernetes Secret.
kubectl create secret generic cloudant --from-literal=url=<URL>
For example:
kubectl create secret generic cloudant --from-literal=url=
You will need this info in your deployment. You can see your secrets by using the following command.
kubectl get secrets
This will display all the secrets you created in their respective clusters.
The IBM Cloud Container Registry provides a multi-tenant private image registry that you can use to safely store and share your Docker images with users in your IBM Cloud account.
Log in to the Container Registry Service to store the Docker image that we created with Docker.
ibmcloud cr login
Find your container registry namespace by running the following command.
ibmcloud cr namespaces
If you don’t have any, create one by using following command.
ibmcloud cr namespace-add <name>
For example:
ibmcloud cr namespace-add aspnetapp-01
Identify your Container Registry by running the following command.
ibmcloud cr info
For example: registry.ng.bluemix.net
registry.ng.bluemix.net
Build and tag (-t) the Docker image by running the command below, replacing REGISTRY and NAMESPACE with the appropriate values.
-t
REGISTRY
NAMESPACE
docker build . -t <REGISTRY>/<NAMESPACE>/myapp:v1.0.0
docker build . -t registry.ng.bluemix.net/aspnetapp-01/myapp:v1.0.0
It will display the following message in the end.
...
Successfully tagged registry.ng.bluemix.net/aspnetapp-01/app:v1.0.0
Push the Docker image to your Container Registry on IBM Cloud.
docker push <REGISTRY>/<NAMESPACE>/myapp:v1.0.0
Verify that the image was pushed successfully by running the following command.
ibmcloud cr image-list
Good work! You set up a namespace in the IBM Cloud Container Registry and pushed a Docker image to your namespace.
Once you have a running Kubernetes cluster, you can deploy your containerized application on top of it. To do so, you create a Kubernetes Deployment configuration. The Deployment instructs Kubernetes on how to create and update instances of your application. Once you create a Deployment, the Kubernetes master schedules the mentioned application instances onto individual Nodes in the cluster. A Kubernetes Deployment Controller continuously monitors those instances that were created. If the Node that’s hosting an instance goes down or is deleted, the Deployment controller replaces it. This provides a self-healing mechanism to address machine failure or maintenance.
To create a deployment, you will create a folder called “kubernetes” and create a deployment.yaml file.
mkdir kubernetes
vi deployment.yaml
# Update <REGISTRY> <NAMESPACE> values before use
# Replace app name instead of get-started-aspnet if you wish to use different name for your app
apiVersion: apps/v1
kind: Deployment
metadata:
name: get-started-aspnet
labels:
app: get-started-aspnet
spec:
replicas: 2
selector:
matchLabels:
app: get-started-aspnet
template:
metadata:
labels:
app: get-started-aspnet
spec:
containers:
- name: get-started-aspnet
image: <REGISTRY>/<NAMESPACE>/myapp:v1.0.0
ports:
- containerPort: 8080
imagePullPolicy: Always
env:
- name: CLOUDANT_URL
valueFrom:
secretKeyRef:
name: cloudant
key: url
optional: true
The deployment get-started-aspnet was created, indicated by the .metadata.name field. The Deployment creates two replicated Pods, indicated by the replicas field. These replicas are needed to handle the traffic in deployment. You can keep it to 1 as well.
The selector field defines how the Deployment finds which Pods to manage. However, more sophisticated selection rules are possible, as long as the Pod template itself satisfies the rule. The Pods labeled app: get-started-aspnet are using the labels field. The Pod template’s specification, or .template.spec field, indicates that the Pods run one container, get-started-aspnet, which runs the <REGISTRY>/<NAMESPACE>/myapp:v1.0.0 Docker image. Open port 8080 so that the container can send and accept traffic. Set the imagePullPolicy of the container to Always. The Secret information has been updated in the env field, like the CLOUDANT_URL that we mentioned while creating our Secret for the Cloudant database.
.metadata.name
replicas
1
app: get-started-aspnet
.template.spec field
<REGISTRY>/<NAMESPACE>/myapp:v1.0.0
imagePullPolicy
Always
env
Create a deployment by using the following command.
kubectl create -f kubernetes/deployment.yaml
The output will display, similar to the following message.
deployment "get-started-aspnet" created
By default, the pod is only accessible by its internal IP within the cluster. Create a Kubernetes Service object that external clients can use to access an application running in a cluster. The Service provides load balancing for an application.
Use the NodePort 8080 to expose the deployment.
kubectl expose deployment get-started-aspnet --type NodePort --port 8080 --target-port 8080
You will see the following message.
service "get-started-aspnet" exposed
To verify that your application is running successfully, you need to check the STATUS of your pod. It should be in a state of Running:
Running
kubectl get pods -l app=get-started-aspnet
It should look like the following:
NAME READY STATUS RESTARTS AGE
It should also show two instances as we have set two replicas in our deployment.
To access your ASP.Net Core application:
ibmcloud cs workers YOUR_CLUSTER_NAME
kubectl describe service get-started-aspnet
http://<WORKER-PUBLIC-IP>:<NODE-PORT>/
This is how you could deploy and access your application in the IKS environment.
Use the following commands to clean up the sample application that we created for this tutorial:
kubectl delete deployment,service -l app=get-started-aspnet
kubectl delete secret cloudant
This concludes a simple, getting-started walkthrough of an ASP.NET Core app deployment in IKS. By following this tutorial, you can take any application that you have developed on your machine, turn it into a Docker container image, and then run that image on IBM Cloud Kubernetes Service. This tutorial also explained how you can put sensitive information into secrets. We have only touched the surface of this technology and I encourage you to explore further with your own pods, replication controllers, and services. You can also put your new skills to the test with the code pattern, Build an airline booking platform on a private cloud.

The Simpsons characters recognition and detection using Keras (Part 1)
Deep Learning : Training a convolutional neural network to recognize The Simpsons characters.
As a big Simpsons fan, I have watched a lot (and still watching) of The Simpson episodes -multiple times each- over the years. I wanted to build a neural network which can recognize characters. I don’t know right now what will be the applications of the neural net (perhaps computing the characters presence in each episode).
This project is not specially difficult but can be time consuming, because I have to manually label many pictures of each character. I didn’t find any The Simpsons characters database on the Internet so I am building it by myself (I am still labeling pictures when I have time). I think it could be useful for other ones. The dataset is already available on Kaggle with exploratory code (in the Kernels section).
After learning and using TensorFlow for different projects, I want to use Keras because of its simplicity (compared to TensorFlow for example) and its capacity (TensorFlow backend) for experimentation. Keras is a Deep Learning library written in Python by Francois Chollet. My approach to solve this problem will be based on convolutional neural networks (CNNs) : multi-layered feed-forward neural networking able to learn many features.
You can find the code on the github repo .
Building the image dataset
The dataset currently features 18 classes/characters (the data on Kaggle contains 20 classes, but currently I used only 18 characters for training). Please check the image below for the characters used. The pictures are under various size, scenes, could be cropped from other characters and are mainly extracted from episodes (season 4 to 24).
The training set includes about 1000 images per character (still labeling data to get to this number). The character is not necessarily centered in each image and could sometimes be with other characters (but it should be the most important part in the picture).
With label_data.py, you can label data from .avi movies : you can get a cropped sub picture (left or right part) or the full picture and then label it by entering a part of the character name (burns for Charles Montgomery Burns).
To add more data, I also use the Keras model. I capture videos and get 3 pictures for each frame I analyzed (left part, right part, full) and then I ask my algorithm to classify each pictures. Afterward, I check each picture it has classified. It’s still manual but it’s faster and it’s an incremental process that’s more and more fast, particularly for “small” characters.
Preprocessing
The first step for preprocessing pictures is resizing them. We need to have all pictures with the same size for training. I will convert data as float32 to save some memory and normalize them (divide by 255.). Then, instead of characters name, I use numbers and thanks to Keras, I can quickly convert those categories to vectors :
import keras
import cv2pic_size = 64
num_classes = 10
img = cv2.resize(img, (pic_size, pic_size)).astype('float32') / 255. ...
y = keras.utils.to_categorical(y, num_classes)
I am splitting my dataset into a training and a testing set : for this, I use sklearn train_test_split function.
Deep Learning Model(s)
Now, let’s begin the “funny” part : defining our model. Right now, we’ll use a feed forward 4 convolutional layers with ReLU activation followed by a fully connected hidden layer (see below for a deeper model). This model is similar to the CIFAR example from Keras documentation. I also use dropout layers to regularize and avoid overfitting. The output layer uses softmax activation to output the probability for each class. I also tried to replace ReLU by ELU (like ReLU but with a mean closer to zero) but it didn’t work.
Categorical Cross Entropy loss is -as often- used. And for the optimizer, I use RMS Prop which is a stochastic gradient descend where we “divide the learning rate for a weight by a running average of the magnitudes of recent gradients for that weight” .
Training the model
For the training, the model is iterating over batches of training set (batch size : 32) for 200 epochs.
As I don’t have a huge data set, I am using data augmentation (which is really simple to use with Keras library). It means doing a number of random variations over the pictures so the model never see the same picture twice. This helps prevent overfitting and helps the model generalize better.
datagen = ImageDataGenerator(
featurewise_center=False, # set input mean to 0 over the dataset
samplewise_center=False, # set each sample mean to 0
featurewise_std_normalization=False, # divide inputs by std
samplewise_std_normalization=False, # divide each input by its std
rotation_range=0, # randomly rotate images in the range
width_shift_range=0.1, # randomly shift images horizontally
height_shift_range=0.1, # randomly shift images vertically
horizontal_flip=True, # randomly flip images
vertical_flip=False) # randomly flip images
This take a while running on CPU (on my computer) so I run it on GPU with AWS EC2, Tesla K80: 8 seconds per epoch. In total, it took 20 minutes (which is really quick for deep learning).
As we can on the plot, after 200 epochs, it seems to have reach the asymptote, without an obvious overfitting. Moreover, the accuracy seems good too.
Classification evaluation
Of course, right now, it’s complicated to have a true model accuracy because of the low number of pictures but as the number of pictures will grow, it will be more pertinent. Thanks to sklearn it’s really easy to print a classification report :
As you can see, the accuracy (f1-sport) is really good : above 90 % for every character except Lisa. The precision for Lisa is 82%. Maybe Lisa is mixed up with other characters.
Indeed, Lisa is often mixed up with Bart. Probably because many pictures of Lisa contain Bart too.
Adding a threshold to improve the accuracy
In order to improve the precision (so, of course decrease the recall, but I would try to not decrease it too much), I thought that I can maybe add a threshold.
Before to talk about a threshold to improve accuracy. I just want to had a famous graph about recall and precision.
I compute some statistics about good and wrong predictions : maximum probability predictions, the probability difference between the best two candidates and the std.
For good predictions : Max : 0.83, Difference Two First : 0.773, STD : 0.21
For wrong predictions : Max : 0.27, Difference Two First : 0.092, STD : 0.07
If the probability of the predicted character (1.) is too low, the standard deviation of the prediction (2.) is too high or the probability difference between the two most likely characters (3.) is too low maybe we can say that we don’t want to predict a character at all.
So I plot those 3 values for the test set to find a line (or a hyperplane) to separate good and wrong predictions. I did it for both characters.
As you can see it’s impossible to find a linear separation and to have a simple threshold, for both graphs, between good and wrong predictions. Of course, we can see that wrong predictions are concentrated in the lower left of each graph but in this corner, there are too many good predictions too. If I choose a threshold (for example, threshold regarding the probability difference and probability of the best candidate), my recall will be lower.
Maybe the best thing, to do to improve the accuracy and not affect too much the recall, is to plot those graphs for every character or for a character with a low precision (e.g. Lisa Simpson).
Moreover, the threshold could be useful for pictures without famous characters or with not character at all. Currently, I do have a “no-character” class in my model but I can probably add with a threshold. I don’t think that we can finding the perfect formula (between the probability of the best prediction, the probability difference and the standard deviation) so I will just focus on the probability of the best prediction.
Recall and Precision regarding the probability of the best prediction
There is classic trade-off between recall and precision and as often we couldn’t maximize recall and precision at the same time. So, it depends what we want exactly.
Regarding the probability minimum for the predicted class, we can plot the F1-score, the recall and the precision.
As we can see, it really depends on the characters. For example, if we focus on Lisa Simpson, it would be interesting to add a probability minimum for predicted class (=0.2), but this threshold will not be really useful for all classes combined.
So regarding of the application, we should add or not a threshold around 0.2–0.4 for the probability minimum for the predicted class.
Improving the CNN model
As I said earlier, I have a four convolutional layers models. To make the neural net understands more details and more complexity, we can get deeper and add more convolutional layers.
It’s what I did. I tried with 6 convolutional layers and going deeper (dimensions of the output space 32, 64, 512 vs 32, 64, 256, 1024) . It has improved the accuracy (precision and recall) as you can see below. The lower precision is 0.89 for Nelson Muntz and we only had 300 training examples for this character.
Moreover, this model converge quicker : only 40 epochs (vs 200). It tooks 15 minutes to train on a Tesla K80.
Visualizing predicted characters
As you can see, the neural network is pretty accurate to recognize and classify characters. Then, I predict characters in a video. Indeed, the predictions are faster enough (less than 0.1 s to predict a picture) to predict multiple frames each second.
If you have any questions, please feel free to contact me and moreover, if you like this post don’t hesitate to recommend it :-).
The dataset is on Kaggle, download it and have fun !
The next steps with a detection model in addition of the classification model are described in Part 2.

In this tutorial, you will learn about blockchain programming from scratch by building a fully decentralized application (DApp), step by step.
You will also learn how to create your own collectable token on the RSK blockchain network using the Truffle framework, Open Zeppelin (OZ) libraries, and build a front end with React, using
create-react-app.
We will create a dapp inspired by Cryptokitties, a popular blockchain game where you can collect and breed digital cats. In this tutorial, instead of collecting felines in our app, we are going to collect exclusive color tokens.
A fungible token represents an asset that can be exchanged for any other asset of equal value in its class.
A currency is an example of a fungible asset. A $100 bill is equal to any other $100 bill, you can freely exchange these bills with one another because they have the same value, no matter the serial number on the specific $100 bill. They are fungible bills.
On the other hand, a Non-Fungible Token (NFT) is a unique token. So collectible items are non-fungible assets, and can be represented by NFTs.
ERC-721 was the first standard, and currently still the most popular standard, for representing non-fungible digital assets.
The most important properties for this kind of asset is to have a way to check who owns what and a way to move things around.
It is easy to create new ERC721-compliant contracts by importing it from the OZ library and we will do so in this tutorial.
The interface for ERC-721 provides two methods:
ownerOf: to query a token’s owner
transferFrom: to transfer ownership of a token
And this is enough to represent an NFT!
In this tutorial, we are going to create an NFT to represent our collectible color tokens.
You will be able to create new color tokens and claim them so that they can be held in a digital blockchain wallet.
Here is a summary of the steps to be taken to build our token:
Steps 1 to 4 are explained in detail in the tutorial link below:
The same webinar is also available in Português.
This article is also available in Português.
The requirements 1 to 3 are explained in detail in the tutorial links below:
For requirement 4, installing Metamask, connecting to RSK testnet, and getting some tR-BTCs, this is explained step-by-step in the tutorial link below:
Create a new folder named
colors.
Inside the folder
colors, do the steps below, following instructions from the tutorial
Setup a project with Truffle and OpenZeppelin
We have 3 requirements to build the frontend:
This is the official template to create single-page React applications. It offers a build setup with no configuration.
To learn more: create react app
In the project folder, at terminal, run:
npx create-react-app app --use-npm
The option
--use-npm is to select npm as package manager.
npx comes with npm 5.2+ and higher, see instructions for older npm versions.
This is a large package and this might take a couple of minutes to show the message of successful installation:
Now you have a new folder named
app and we will customize our frontend later. folder
app
cd app npm install -E web3@1.2.7
The option
-E is to save dependencies with an exact version rather than using npm’s default.
cd app npm install -E bootstrap@4.4.1
As I said before, the option
-E is to save dependencies with an exact version rather than using npm’s default.
Come back to the project folder, open
truffle-config.js file in VS Code); const path = require("path"); module.exports = { networks: { testnet: { provider: () => new HDWalletProvider(mnemonic, ''), network_id: 31, gasPrice: Math.floor(gasPriceTestnet * 1.1), networkCheckTimeout: 1e9 }, }, contracts_build_directory: path.join(__dirname, "app/src/contracts"), compilers: { solc: { version: "0.5.7", } } }
It looked like this:
We add the library
path to use with a new parameter
contracts_build_directory that defines the locale where files for contracts artifacts, like abi and deployed addresses are saved.
It will be located in a different folder:
app/src/contracts.
We will create a smart contract named
Color.sol that will inherit the ERC721 definition from the OZ library.
In the Contracts folder, create a new file named
Color.sol.
Copy and paste the smart contract from the following gist, or inline below:
pragma solidity 0.5.7; import '@openzeppelin/contracts/token/ERC721/ERC721Full.sol'; contract Color is ERC721Full { bytes3[] public colors; mapping(bytes3 => bool) private _colorExists; constructor() ERC721Full("Color", "COLOR") public { } // E.G. color = "#FFFFFF" function mint(bytes3 _color) public { require(!_colorExists[_color], "color exists"); uint _id = colors.push(_color); _mint(msg.sender, _id); _colorExists[_color] = true; } }
It looked like this:
To create our ERC-721 Token, we will import
ERC721Full from OZ.
This library itself imports several other libraries such as
SafeMath.sol,
the standards for this kind of token and some extra features,
like enumeration and metadata.
With metadata we can customize our token by giving it a name and a symbol at constructor.
This function gets run only once; whenever the smart contract is created the first time, i.e., deployed to the blockchain.
We are calling the constructor function of the parent smart contract
ERC721Full and passing in custom arguments like the name
Color and the symbol
COLOR.
The color management is performed with the variable
colors, which is an array of colors and
_colorExists, which is a fast “lookup” to know when a color is already minted.
Also we have a function to create new color tokens.
This is the basic structure of the function.
It will accept 1 argument of the
bytes3 type, which will be a hexadecimal code that corresponds to the token’s color.
For example, if we want to create a green token, we will pass “#00FF00” when we call this function. Or if we want to create a red token, we’ll use “#FF0000”.
In the terminal, run this command:
truffle compile
First of all, we need to create a file in Truffle structure with instructions to deploy the smart contract.
Folder
migrations which is automatically created by Truffle.
(source: running migrations)
In the
migrations folder, create the file
2_deploy_contracts.js
Copy and paste this code:
const Color = artifacts.require("Color"); module.exports = function(deployer) { deployer.deploy(Color); };
It looked like this:
In the terminal, run this command:
truffle migrate --network testnet
Wait a few minutes while the transactions for the smart contract deployments are sent to the blockchain.
The migrate command will compile the smart contract again if necessary.
First, it deploys the smart contract
Migrations.sol, file generated by Truffle:
This is the transaction at RSK testnet:
0x3de61b8983dc3db2ca21a9d10106a19c445885fcb7040774bd6937daf94a4702
And then it deploys our smart contract
Color.sol:
This is the transaction at RSK testnet:
0x2c2d2932a7d637fbba100b5c482c1fa1899c4fe24bd1a458976a93cee6c5ba85
A tip: if there is a communication problem with the testnet between the publication of Migrations.sol and Color.sol, just run the migrate command again, it will deploy only what is missing.
Congratulations!
Our NFT Color is published at RSK Testnet.
Save the contract address of token, it can be used later:
tokenAddress = "0x5505a54a8F3e63D37095c37d9f8AcF0f4900B61F"
Now let’s start building out the front end that will interact with the smart contract. It will allow us to create new color tokens, and list out all of the existing tokens in your wallet.
In the
app folder, we need to customize some files.
In the
app\public folder, open
index.html file.
At
head section, update the
title:

In the
app\src folder, open
index.js file and add a line to use bootstrap in out project
import 'bootstrap/dist/css/bootstrap.css';
Also remove this line:
import './index.css';
The final
index.js is this. You can overwrite it with the code from following gist, or inline below:
import React from 'react'; import ReactDOM from 'react-dom'; import 'bootstrap/dist/css/bootstrap();
At this point, your completed
index.js file should looks like this:
Open
App.css file and overwrite it with the code from the following gist, or copy and paste the code below:
.token { height: 150px; width: 150px; border-radius: 50%; display: inline-block; }
This code customizes the appearance for tokens.
This is the result:
Open
App.js file and overwrite it with the code from following gist, or copy and paste the code below:
import React, { Component } from 'react'; import Web3 from 'web3'; import './App.css'; import Color from './contracts/Color.json'; function colorHexToString(hexStr) { return '#' + hexStr.substring(2); } function colorStringToBytes(str) { if (str.length !== 7 || str.charAt(0) !== '#') { throw new Error('invalid color string'); } const </form> </div> </main> </div> <hr/> <div className="row text-center"> { this.state.colors.map((colorStr, key) => { return ( <div key={key} <div className="token" style={ { backgroundColor: colorStr } }></div> <div>{colorStr}</div> </div> ); })} </div> </div> </div> ); } } export default App;
Import web3 here:
import Web3 from 'web3'
This part is connected to the RSK Testnet using the injected web3 provider, in this case, MetaMask:); }
To load the instance of smart contract Color already published, we need to load the informations from Truffle deploy:
import Color from './contracts/Color.json';
And after connecting successfully, the function
loadBlockchainData loads accounts, network information and the smart contract Color.], }); } }
Also we have a mint function at App.js which sends a transaction to the network calling the mint function in the smart contract.
mint = (colorStr) => { const colorBytes = colorStringToBytes(colorStr); this.state.contract.methods .mint(colorBytes) .send({ from: this.state.account }) .once('receipt', (receipt) => { console.log ('transaction receipt: ', receipt) this.setState({ colors: [...this.state.colors, colorStr], }); }); }
Finally, the
render() function is responsible for the HTML code for the application. It has 3 primary functions:
In the
app folder, at terminal, run:
npm start
It will automatically open the default browser at
If it does not open, you can enter the local url manually in the browser.
Metamask automatically detects that our app would like to connect, authorize this action by clicking on the
Connect button.
And this is our frontend!
The colors are saved with hexadecimal representation for each.
To know more about color and hex color codes:
Some color codes:
Choose a color and enter your hexadecimal representation in the info text field, and click on the
MINT button.
It will call the
mint() function at the smart contract instance Color, with the color that you defined.
I will enter the color red, value
#FF0000.
Do not forget to use the symbol
#
Click on the
confirm button.
Great! Now I have my first color collectable token:
I would like to mint the blue color:
#0000FF
Wait for a few seconds for your transaction to be mined…
And now I have two colors in my collection!
And my collection is growing!
Hope it was easy for you to create a NFT!
I showed you how to connect Truffle to the RSK network and deploy your own NFT using the OZ libraries, and that they work on the RSK network.
This tutorial was inspired by Gregory McCubbin’s tutorial, from dApp University. Check out the original article.
Our goal is to join forces and give options to people who believe in smart contracts based on Ethereum, and also believe in the power of Bitcoin, through RSK.

Hello guys, Thank you for your help on my last question. I have another very simple question. I have been trying to figure this out for a while, and since my professor doesn't help me in the class I...
Never mind lol I'm retarded. I got it, I was using an int for the variable, not a char. Thanks for the help!
Alright, after a little bit more research I figured it out (at least I thought.) This is what I came up with:
#include <iostream>
using namespace std;
int main ()
{
int day;

Hello,
So I am new here, from what I have seen people here know what they're doing :) (not that my question is hard at all). So I am taking a programming class at my school. I have dabbled... | http://forums.codeguru.com/search.php?s=7d59d9703156380ef7a2a124bd1238bd&searchid=9125997 | CC-MAIN-2016-30 | refinedweb | 138 | 84.37 |
Suppose I need to use a library which is accessed via a global variable e.g. jQuery, lodash, d3, etc. Let's assume that the library does not export modules of any flavor.
What is the best way to import such a library?
This seems counterproductive -- modules are a superior method of sharing code. Nonetheless, it is apparently an option some pursue.
Example usage with lodash, which uses the _ global variable, in an adapter:
_
// adapters/my-custom-adapter.js
findQuery: function(store, type, query) {
return this.findAll(store, type).then(function(data) {
return _.filter(data, _.matches(query))
});
}
Another option is to wrap the global in a module so it can be imported in the standard fashion.
Example usage:
// vendor/shims.js
define('lodash', [], function() {
'use strict';
return {default: _};
});
// adapters/my-custom-adapter.js
import _ from 'lodash';
findQuery: function(store, type, query) {
return this.findAll(store, type).then(function(data) {
return _.filter(data, _.matches(query))
});
}
Sidebar Anyone know why the transpiler doesn't support the module declaration (which I think is part of the ES6 spec)?
module
module 'lodash' {
export default: _;
}
So I guess option 2b is modify the transpiler to support module.
Similar to option 2, but each vendored lib gets its own file.
// vendor/lodash.js
export default _;
// adapters/my-custom-adapter.js
import _ from 'vendor/lodash';
findQuery: function(store, type, query) {
return this.findAll(store, type).then(function(data) {
return _.filter(data, _.matches(query))
});
}
It looks like there is some precedent in ES6 polyfills for loading globals when all else fails. That is, when a module has not been registered, there is a final check to see if the required module name is defined globally. I'm curious if this is considered a bad idea.
// adapters/my-custom-adapter.js
import _ from '_';
findQuery: function(store, type, query) {
return this.findAll(store, type).then(function(data) {
return _.filter(data, _.matches(query))
});
}
Am I missing potential solutions? Which solution is preferable?
Thanks!
Have a look at
Thanks for the reply!
Using Ember's DI facilities is certainly one solution, but I'm not sure it's always the right solution. From my perspective, modules, DI and Ember DI are different creatures befitting different problems.
inject
A logger is a good fit for DI. We want to instantiate and share a single logger instance at runtime. We want the ability to swap out logger implementations.
Conversely, lodash is a bunch of utility functions, and is not a good fit for DI. It will only ever have a single implementation. We don't want the ability (or onus) to inject lodash. We want to depend on it concretely.
Ember DI has the following mechanics. In an initializer, I can do something like:
var logger = new Logger();
application.register('logger:main', logger);
application.inject('controller', 'logger', 'logger:main');
This says that my instance of logger is registered under the name "logger:main". Then, I can inject logger into all controllers (as specified by "controller"). It will appear on a given controller as the property logger i.e. can be accessed via this.logger.
logger
this.logger
This is pretty neat, but also pretty limiting (has anyone ever been happy with a DI framework?).
Limitation 1. The inject target, 'controller' has to be a valid "factory name". That is, it must be a "major framework class".
'controller'
Limitation 2. The inject target, must be instantiated by the framework
Limitation 3. The dependency is injected as an attribute of the object.
Let's return to lodash, the pile of utility functions. If I define a vanilla JS class (POJO), which in turn depends on lodash, limitations 1 and 2 are killers. I instantiate POJOs myself, and they're not major framework classes, so I cannot take advantage of Ember DI.
But even if I'm working on a major framework class, do I really want lodash's _ to become a property of the object? Not really. this._ seems weird, and I don't want to bind this everywhere just to access _.
this._
this
The availability of a Ember DI does not obviate the need for modules because 1. Ember DI is limited, and 2. DI is not always the right pattern.
I think it is important to create module shims for globals before we even get into register/inject territory; a sacred shim barrier over which no code may cross unless it is wrapped by a module. In other words, I would modify the blog post example to:
import io from 'socket-io';
// stuff
app.register('io:main', io, {instantiate: false});

In this article, we will learn about Logic Gates in Python. Let’s look at each of the logic gates in Python in detail with some easy examples.
All of us are quite familiar while implementing logic gates in the processing of electrical signals and are widely used in the electrical and electronics industry. They are used in the diodes and transistors so that we can design by proper alignment of these electronic devices. In this article we will learn about the implementation of some basic gates ‘and‘, ‘or‘ ,’not‘ , ‘nand‘ ,’nor‘ in Python 3.x or earlier.
These gates can be implemented by using user-defined functions designed in accordance with that of the truth table associated with the respective gate.
def AND (a, b): if a == 1 and b == 1: return True else: return False # main function if __name__=='__main__': print(AND(0,0)) print(AND(1,0)) print(AND(0,1)) print(AND(1,1))
False False False True
def OR(a, b): if a == 1: return True elif b == 1: return True else: return False # main function if __name__=='__main__': print(OR(0,0)) print(OR(1,0)) print(OR(0,1)) print(OR(1,1))
False True True True
def NOT(a): if(a == 0): return 1 elif(a == 1): return 0 # main function if __name__=='__main__': print(OR(0)) print(OR(1))
True False
def NAND (a, b): if a == 1 and b == 1: return False else: return True # main function if __name__=='__main__': print(NAND(0,0)) print(NAND(1,0)) print(NAND(0,1)) print(NAND(1,1))
True True True False
def NOR(a, b): if(a == 0) and (b == 0): return True elif(a == 0) and (b == 1): return False elif(a == 1) and (b == 0): return False elif(a == 1) and (b == 1): return False # main function if __name__=='__main__': print(NOR(0,0)) print(NOR(1,0)) print(NOR(0,1)) print(NOR(1,1))
True False False False
In this article, we learned how to implement logic gates in Python 3.x. Or earlier. We also learned about two universal gates i.e. NAND and NOR gates. | https://www.tutorialspoint.com/logic-gates-in-python | CC-MAIN-2021-21 | refinedweb | 360 | 59.06 |
Add a new, flexible UI for adding and configuring integrations.
Review Request #10431 — Created Feb. 26, 2019 and submitted
The old integrations UI worked alright when we only had a few
integrations available, but didn't scale well. It was harder to visually
separate the configurations from the available integrations, and really
hard to see at a glance how many configurations you had in total. It
also only worked in the Django administration UI, meaning it wasn't
usable in, say, RBCommons or Splat Team Admin UIs.
This change completely redoes the UI for integrations, while at the same
time making it suitable for use outside of the Django administration UI.
Now, configurations are presented as a config forms list, showing an
icon for the integration, the configuration name, integration name, and
the enabled/disabled state.
Above the list is a button for adding an integration, which pops up a
tile-based menu of all integration options. Down the road, this can be
expanded to allow searching or filtering based on categories, but for
now it provides a good way of quickly seeing what's available.
The new UI has been built on top of the new config forms work, providing
a consistent appearance wherever it's embedded.
Tested adding new integrations via the popup.
Tested editing existing integrations.
Tested the integrations popup on various screen sizes, including very
large and very small screens.
Tested that the integration state was reflected in the list item.
Tested custom URL namespaces, and that they're respected everywhere. | https://reviews.reviewboard.org/r/10431/ | CC-MAIN-2020-10 | refinedweb | 255 | 54.73 |
Elastic Nodes Example#.
Node Class Definition#
The
Node class serves three purposes:
-
Painting a yellow gradient “ball” in two states: sunken and raised.
-
Managing connections to other nodes.
-
Calculating forces pulling and pushing the nodes in the grid.
Let’s start by looking at the
Node class declaration.
class Node(QGraphicsItem): # public Node(GraphWidget graphWidget) def addEdge(edge): *> = QList<Edge() enum { Type = UserType + 1 } int type() override { return Type; } def calculateForces(): advancePosition = bool() boundingRect = QRectF() shape = QPainterPath() def paint(painter, option, widget): protected: itemChange = QVariant(GraphicsItemChange change, QVariant value) def mousePressEvent(event): def mouseReleaseEvent(event): # private *> = QList<Edge() newPos = QPointF() graph = GraphWidget():
def __init__(self, graphWidget): self.
def addEdge(self, edge): edgeList << edge edge.adjust() QList<Edge *> Node::edges().
def calculateForces(self): if (not scene() or scene().mouseGrabberItem() == self) {.,
mouseGrabberItem() ). Because we need to find all neighboring (but not necessarily connected) nodes, we also make sure the item is part of a scene in the first place.
# Sum up all forces pushing this item away xvel = 0 yvel = 0 > items = scene().items() for item in items: node = qgraphicsitem_cast<Node *>(item) if (not node) continue vec = mapToItem(node, 0, 0) dx = vec.x() dy = vec.y()
items() to find all items in the scene, and then use weight = (edgeList.size() + 1) * 10 for edge in qAsConst(edgeList): vec = QPointF() if (edge.sourceNode() == self)().
def advancePosition(self): if (newPos == pos()) return False setPos(newPos) return True
The
advance() function updates the item’s current position. It is called from
GraphWidget::timerEvent(). If the node’s position changed, the function returns true; otherwise false is returned.
def boundingRect(self): adjust = 2 def QRectF(adjust,adjust,adjust.
def shape(self): path = QPainterPath()).
def paint(self, painter, option, arg__0): painter.setPen(Qt.NoPen) painter.setBrush(Qt.darkGray) painter.drawEllipse(-7, -7, 20, 20) gradient = QRadialGradient(-3, -3, 10) if (option.state QStyle.State_Sunken) { gradient.setCenter(3, 3) gradient.setFocalPoint(3, 3) gradient.setColorAt(1, QColor(Qt.yellow).lighter(120)) gradient.setColorAt(0, QColor(Qt.darkYellow).lighter
yellow to.
def itemChange(self, GraphicsItemChange change, QVariant value): switch (change) { ItemPositionHasChanged: = case() for edge in qAsConst .
def mousePressEvent(self, event): update() QGraphicsItem.mousePressEvent(event) def mouseReleaseEvent(self,).
Edge Class Definition#(QGraphicsItem): # public Edge(Node sourceNode, Node destNode) sourceNode = Node() destNode = Node() def adjust(): enum { Type = UserType + 2 } int type() override { return Type; } protected: boundingRect = QRectF() def paint(painter, option, widget): # private source, = Node() sourcePoint = QPointF() destPoint = QPointF() arrowSize = 10.
def __init__(self, sourceNode, destNode): self.source = sourceNode self.dest = destNode setAcceptedMouseButtons(Qt.NoButton) source.addEdge(self) dest.addEdge(self).
Edge::sourceNode = Node() return source Edge::destNode = Node() return dest
The source and destination get-functions simply return the respective pointers.
def adjust(self): if (not source or not dest) return line = QLineF(mapFromItem(source, 0, 0), mapFromItem(dest, 0, 0)) length = line.length() prepareGeometryChange() if (length > qreal(20.)) { edgeOffset = QPointF(.
def boundingRect(self): if (not source or not dest) def QRectF(): penWidth = 1.
def paint(self, painter, arg__0, arg__1): if (not source or not dest) return line = QLineF angle = std::atan2(-line.dy(), line.dx()) sourceArrowP1 = sourcePoint + QPointF(sin(angle + M_PI / 3) * arrowSize, cos(angle + M_PI / 3) * arrowSize) sourceArrowP2 = sourcePoint + QPointF(sin(angle + M_PI - M_PI / 3) * arrowSize, cos(angle + M_PI - M_PI / 3) * arrowSize) destArrowP1 = destPoint + QPointF(sin(angle - M_PI / 3) * arrowSize, cos(angle - M_PI / 3) * arrowSize) Class Definition#
GraphWidget is a subclass of
QGraphicsView , which provides the main window with scrollbars.
class GraphWidget(QGraphicsView): Q_OBJECT # public GraphWidget(QWidget parent = None) def itemMoved(): slots: = public() def shuffle(): def zoomIn(): def zoomOut(): protected: def keyPressEvent(event): def timerEvent(event): #if QT_CONFIG(wheelevent) def wheelEvent(event): #endif def drawBackground(painter, rect): def scaleView(scaleFactor): # private timerId = 0 centerNode = Node().
def __init__(self, parent): QGraphicsView.__init__(self, parent) scene = QGraphicsScene(self)
NoIndex . The scene then gets a fixed
scene rectangle , and is assigned to the
GraphWidget view.
The view enables
CacheBackground to cache rendering of its static, and somewhat complex, background. Because the graph renders a close collection of small items that all move around, it’s unnecessary for Graphics View to waste time finding accurate update regions, so we set the
BoundingRectViewportUpdate viewport update mode. The default would work fine, but this mode is noticably faster for this example.
To improve rendering quality, we set
Antialiasing .
The transformation anchor decides how the view should scroll when you transform the view, or in our case, when we zoom in or out. We have chosen1 = Node(self) node2 = Node(self) node3 = Node(self) node4 = Node(self) centerNode = Node(self) node6 = Node(self) node7 = Node(self) node8 = Node(self) node9 = Node(self) scene.addItem(node1) scene.addItem(node2) scene.addItem(node3) scene.addItem(node4) scene.addItem(centerNode) scene.addItem(node6) scene.addItem(node7) scene.addItem(node8) scene.addItem(node9) scene.addItem(Edge(node1, node2)) scene.addItem(Edge(node2, node3)) scene.addItem(Edge(node2, centerNode)) scene.addItem(Edge(node3, node6)) scene.addItem(Edge(node4, node1)) scene.addItem(Edge(node4, centerNode)) scene.addItem(Edge(centerNode, node6)) scene.addItem(Edge(centerNode, node8)) scene.addItem(Edge(node6, node9)) scene.addItem(Edge(node7, node4)) scene.addItem(Edge(node8, node7)) scene.addItem.
def itemMoved(self): if (not.
def keyPressEvent(self, event): switch (event.key()) { Qt.Key_Up: = case() centerNode.moveBy(0, -20) break Qt.Key_Down: = case() centerNode.moveBy(0, 20) break Qt.Key_Left: = case() centerNode.moveBy(-20, 0) break Qt.Key_Right: = case() centerNode.moveBy(20, 0) break Qt.Key_Plus: = case() zoomIn() break Qt.Key_Minus: = case() zoomOut() break Qt.Key_Space: = case() Qt.Key_Enter: = case() shuffle() break default: QGraphicsView.keyPressEvent(event)
This is
GraphWidget's key event handler. The arrow keys move the center node around, the ‘+’ and ‘-’ keys zoom in and out by calling
scaleView(), and the enter and space keys randomize the positions of the nodes. All other key events (e.g., page up and page down) are handled by
QGraphicsView ‘s default implementation.
def timerEvent(self, event): Q_UNUSED(event) *> = QList<Node() > items = scene().items() for item in items: if (Node node = qgraphicsitem_cast<Node >(item)) nodes << node for node in qAsConst(nodes): node.calculateForces() itemsMoved = False() for node in qAsConst(nodes): if (node.advancePosition()) itemsMoved = True if (not.
def wheelEvent(self, event): scaleView(pow(2., -event.angleDelta().y() / 240.0))
In the wheel event handler, we convert the mouse wheel delta to a scale factor, and pass this factor to
scaleView(). This approach takes into account the speed that the wheel is rolled. The faster you roll the mouse wheel, the faster the view will zoom.
def drawBackground(self, painter, rect): Q_UNUSED(rect) # Shadow sceneRect = self.sceneRect() rightShadow = QRectF(sceneRect.right(), sceneRect.top() + 5, 5, sceneRect.height()) bottomShadow = QRectF(sceneRect.left() + 5, sceneRect.bottom(), sceneRect.width(), 5) if (rightShadow.intersects(rect) or rightShadow.contains(rect)) painter.fillRect(rightShadow, Qt.darkGray) if (bottomShadow.intersects(rect) or bottomShadow.contains(rect)) painter.fillRect(bottomShadow, Qt.darkGray) # Fill gradient = QLinearGradient textRect = QRectF(sceneRect.left() + 4, sceneRect.top() sceneRect.width() - 4, sceneRect.height() - 4) message(tr("Click = QString() "wheel or the '+' and '-' keys"))
drawBackground() . We draw a large rectangle filled with a linear gradient, add a drop shadow, and then render text on top. The text is rendered twice for a simple drop-shadow effect.
This background rendering is quite expensive; this is why the view enables
CacheBackground .
def scaleView(self, scaleFactor): factor = transform().scale(scaleFactor, scaleFactor).mapRect(QRectF(0, 0, 1, 1)).width() if (factor < 0.07 or factor > 100) return scale(scaleFactor, scaleFactor)
The
scaleView() helper function checks that the scale factor stays within certain limits (i.e., you cannot zoom too far in nor too far out), and then applies this scale to the view.
The main() Function#.

Hi
I just started with python, and trying to implement some system admin tasks and running into some rough.
Basically I need to do some task on whichever share exists on their corresponding server.
eg
Server A has shares 1,2 and 3
Server B has share 1 and so on.
Any help is appreciated :)
pseudocode
while not Done:
Prompt for IP
while not Flag
prompt for shares
def get_config(): config_list = [] done = False deny = 'n' counter = 1 while not done: print " Type n or N to exit " ip = raw_input("Enter IP: ") print "you entered ", ip if ip.lower() == deny.lower(): done = True flag = True else: config_list.append(ip) flag = False while not flag: share = raw_input("Enter Shares : ") if share.lower() == deny.lower(): flag = True else: config_list.append(share) print "Config File Reads ", config_list
This works & after entering the values,I get an array like
[ 192.168.0.12 , Share1, Share2, 192.168.0.22, Share 1, 192.168.0.14, Share5, Share6, Share9 ]
Now for each IP, I need to do some action the shares on that server.
as in
for ip 192.168.0.12,
do task a on Share1,Share2
for ip 192.168.0.22,
do task a on Share1
and so on.....
I'm struggling how to implement the above. Any thoughts? | https://www.daniweb.com/programming/software-development/threads/327273/list-manipulations | CC-MAIN-2019-09 | refinedweb | 216 | 84.17 |

From the President
It’s Been Grand
T
his year has certainly gone by quickly, and I want to borrow a phrase of a friend of mine from Rock Hill: “It’s been grand.” I still feel honored to have served as president of SCACPA—the primary volunteer organization of the profession—but my position was made easy with the help of many others. I was lucky to have had a strong, vocal, energetic Board of Directors, a willing and capable staff at SCACPA, and a dedicated group of committee chairs that stayed on task for the year. I would not be telling the truth if I said there was no stress involved with leading the association, but I definitely feel that it was well worth the time and effort.
I still feel honored to have served as president of SCACPA— the primary volunteer organization of the profession—but my position was made easy with the help of many others.
Over the past couple of years I have traveled to Washington, New York, Dallas, Amelia Island, Tampa, Tucson and Las Vegas to work with the AICPA and to add a voice from South Carolina. During the last five years the SCACPA Board has met in Charleston, Flat Rock, Asheville, Tryon and Columbia for productive planning retreats. The guidelines from the AICPA and retreats have kept the Board and staff on target over the years. I have witnessed changes in SCACPA over the past couple of years which deserve recognition. Our CPA Day at the State House event has improved every year and certainly helps our legislative efforts, which are an important role of SCACPA. The Peer Review program has grown due to new legislation, and SCACPA has not only taken this on but also improved the program. CPE had remained on the leading edge of professional issues and has stayed competitive in this new environment. We now have a Young CPA Leadership Cabinet, which will bring a younger voice into the leadership of SCACPA. We have worked hard to assist and work with the local chapters, which in effect helps improve the entire Association. The SCACPA staff and Erin Hardwick’s leadership should be commended for all their good work in these endeavors. As I mentioned in my last article, the Board has made great strides in all of our Five Bold Steps for 2009. We are already focused on our priorities for 2010, and have developed attainable goals to achieve our agenda. I want to thank the Board again for their commitment to SCACPA, and encourage them to keep up the good work. As I said, it’s been grand. n Pictured Top: AICPA CEO Barry Melancon, SCACPA President Charlie Redfern, SCACPA Executive Director Erin Hardwick and AICPA Board Chair Bob Harris.

Sampling of 2009 TAX LAW CHANGES by Angela L. Polk, MAcc, CPA SCACPA member since 1988
This article is a brief introduction to various law changes impacting 2009 made by the American Recovery and Reinvestment Act of 2009—which for the purposes of this article is referred to as “the Act.” ENHANCED TAX CREDIT FOR FIRST-TIME HOMEBUYERS In an attempt to help the housing industry, the Act included an enhanced tax credit for first-time homebuyers. The new credit applies to homes purchased on or after January 1, 2009, through the end of November 2009. This also includes residences under construction, as long as the taxpayer owns and occupies by the November 30 deadline. The law raises the maximum credit amount from the 2008 limit of $7,500 to $8,000. It also provides that this revised credit does not have to be repaid. Further, the revised credit only has a three-year recapture provision, versus the 15-year period that applies for 2008. The new credit may also be claimed on an amended 2008 return if the taxpayer does not want to wait until 2009 to claim the credit. Please note, however, that the IRS is reviewing the returns with additional scrutiny due to

the number of fraudulent claims that have been filed. The Service says that the processing time is longer—12 to 16 weeks instead of the usual eight to 12 weeks. AMERICAN OPPORTUNITY TAX CREDIT The Act also includes a measure aimed at making college more affordable for low and moderate-income students. The new provision temporarily replaces the Hope tax credit with the American Opportunity tax credit for 2009 and 2010. The maximum amount of the American Opportunity tax credit is $2,500. The credit is 100 percent of the first $2,000 of qualifying expenses and 25 percent of the next $2,000—so the maximum credit of $2,500 is reached when a student has qualifying expenses of $4,000 or more. The tax credit is available for up to four years. The Act expands the qualifying expenses from just tuition and fees to include textbooks. Forty percent of the credit is also refundable, and adjusted gross income limits were expanded. The credit begins phasing out at $80,000 for single to $160,000 for joint filers. CHANGES TO SECTION 529 Additionally, the definition of higher education expenses under Section 529 (qualified tuition) plans was expanded to cover computer technology and equipment, internet access and other related services for 2009 and 2010. Prior to the Act, a computer did not qualify unless it was required by the college or by a specific degree program or course. NET OPERATING LOSS (NOL) PAYBACK PERIOD EXTENDED Small businesses were also extended a longer net operating loss (NOL) carryback period for 2008 losses. Normally, losses are only carried back two years. The Act allows an
(888) 557-4814 |
election to be made to carry the NOL back three to five years. The election is required to be filed no later than the due date, including extensions for filing the tax return for the tax year of the NOL. If the business has a fiscal year beginning in 2008, they still have an opportunity to benefit from this expanded carryback period. Small businesses are defined in terms of gross receipts. The average gross receipts for the three years prior to the year generating the NOL has to be $15 million or less. ALTERNATIVE MINIMUM TAX RELIEF The Act provides temporary relief from alternative minimum tax (AMT) for 2009 by increasing the exemption amounts above last year’s levels and allowing nonrefundable credits to offset AMT as well as regular tax. Without this relief, it was previously estimated that more than 20 million additional taxpayers would have faced paying the tax on their 2009 returns. For tax years beginning in 2009, the AMT exemption amounts are increased as follows: $70,950 in the case of married individuals filing a joint return and surviving spouses; $46,700 in the case of unmarried individuals other than surviving spouses; and $35,475 in the case of married individuals filing a separate return. VARIOUS OTHER CREDITS There are numerous other credits—far too many to cover in one article—such as extension of the 50 percent bonus depreciation, the $250,000 179 expense limitation, and others included in this legislation impacting numerous individuals and businesses. There are also other law changes such as the “Worker, Retiree, and Employer Recovery Act of 2008” that also have an impact in 2009. For example, that act included provisions for required
minimum distributions (RMDs) in 2009. Retirement plan and IRA account owners and their beneficiaries are allowed to waive their required minimum distributions for 2009. If distributions have already been taken in 2009 (that are not RMDs for 2008) and the taxpayer would benefit from the deferral, the distribution may qualify for a rollover to another eligible retirement plan, thereby saving the deferral. Please note that individuals who chose to delay taking their 2008 RMD until April 1, 2009 (e.g., retired employees and IRA owners who turned 70 ½ in 2008) are still required to take those distributions in 2009. If a beneficiary, on the other hand, is receiving distributions over a five-year period from an inherited account, he or she can waive the distribution for 2009, effectively permitting the beneficiary to take distributions over a six-year period. Additionally, designated beneficiaries of Roth IRAs may also waive their RMDs, thereby allowing them to avoid selling reduced value assets to make an otherwise required distribution. The main idea here is to note that there are a lot of changes this year that we need to be aware of. Unfortunately or fortunately, depending on your view, that means a lot of reading. n ANGELA L.

South Carolina Tax Realignment Commission Convenes The South Carolina Tax Realignment Commission (TRAC) held its first organizational meeting on September 9, 2009. Burnie Maybank with Nexsen Pruitt Law Firm, former director of the state Department of Revenue, was elected TRAC chairman. Bob Steelman, with Michelin North America, was elected vice chairman. After the election of officers, Commission staff presented the legislation behind their creation and reiterated their charge to make recommendations to the General Assembly for changes to the state’s tax structure by March 2010. The legislation requires that the recommendations ensure a system that is adequate, equitable and efficient.
10
The Commission began their discussions by looking at the state’s sales tax exemptions. It was pointed out that South Carolina has exemptions totaling some $2.7 billion, while actual sales tax collections were only $2.3 billion. Chairman Maybank said he expected the next two meetings of the Commission would focus on discussing each and every one of the exemptions. After reviewing sales tax—including admissions, accommodations and fuel tax—the Commission will then look at the corporate tax structure. The TRAC met again on September 30, 2009. The Commission heard a presentation from the state’s Chief Economist, Dr. Bill Gillespie, on South Carolina’s revenue situation. Gillespie presented information pertaining to

from several different professional associations that have similar concerns to discuss ways to address these concerns in a collaborative approach.
OTHER STATE LEGISLATIVE ISSUES
FEDERAL ISSUES
Several of the larger exemptions, or categories of exemptions, generated a number a questions prompting the Chairman to announce they would have separate discussions. Based on the meeting, four categories have been identified for more in-depth discussion:
Federal/State Tax Conformity
Proposed Registration of Tax Preparers
SCACPA continues to work toward early confirmation of federal-state tax conformity. Discussions with the state Department of Revenue and key legislators are now taking place to lay the groundwork for the introduction of conformity legislation early in 2010.
1) Motor Fuel Tax. While there is currently a state motor fuels tax that directly funds roads and bridges, sales tax is not applied. Currently, the exemption represents $500 million annually.
Helping the SC Board of Accountancy Meet its Mission
In testimony before the House Ways and Means Oversight Committee on June 4, 2009, Internal Revenue Service Commissioner Douglas Shulman announced that the IRS plans to make recommendations to ensure that tax preparers adhere to high ethical standards. Legislation to regulate preparers has generally been proposed by members of Congress as a partial response to 1) the high error rate associated with Earned Income Tax Credit (EITC) claims; and 2) consumer protection concerns associated with refund anticipation loans (RALs).
2) Communications Services. This includes land line and wireless toll charges, internet use, broadband, voice messages, texts and other services, with exemptions representing approximately $73 million annually. 3) Medical/Prescription. Prosthetic
As the state Department of Labor Licensing and Regulation seeks economies of scale by consolidating the licensing, renewals, administration, investigative and legal representation functions for the 40 boards and commissions under its jurisdiction, regulating boards are becoming increasingly frustrated by their own inability to meet their respective missions of protecting the public. SCACPA recently convened a meeting with representatives
The IRS has authority to regulate tax return preparers through the penalty authority under current law. The Internal Revenue Code permits the IRS to assess (among others) penalties for the understatement of a taxpayer’s liability (section 6694); the continued next page

administration
The federal government also regulates CPAs, attorneys and enrolled agents through the IRS’s Office of Professional Responsibility (OPR). OPR enforces Circular 230, which governs the practice these professionals before the Service. OPR has the authority to identify standards of performance and discipline these Circular 230 practitioners through disbarment and other sanctions.
House nor Senate
The IRS announcement did not offer specifics on what the proposals may entail, though unconfirmed reports indicate that registration, an exam, a requirement for continuing professional education and possibly the granting of a certificate are being considered. AICPA representatives are meeting with congressional staff and IRS officials to discuss tax preparer registration in the past, and will continue to do so.
Proposed Consumer Financial Protection Agency (CFPA) As the proposed legislation—H.R 3126—read in September 2009, it had the unintended consequence of going beyond the regulation of the sale of products related to consumer credit and finance and impacted independent services provided in the context of professional relationships.

and Congress have stated that they do not want the estate tax to expire; however, neither the has taken any steps legislatively. The proposed legislation would have resulted in redundant regulation of CPAs and certified public accounting firms that are already subject to appropriate oversight by the IRS, Treasury, state boards of accountancy and AICPA’s professional and ethical standards. In early October as a result of intense advocacy efforts by AICPA and SCACPA, CPAs are currently exempted from the legislation. CPAs should not, of course, be exempt from the Consumer Financial Protection Agency’s regulation when acting in other capacities and AICPA would support additional oversight of financial products, such as refund anticipation loans. The legislation continues to be discussed in Congress as we go to publication of The SCCPA Report. See SCACPA’s Web site for emerging information on this topic.
South Carolina CPA Report w November/December 2009
President’s Budget Proposal for Mandatory E-File for Individuals President’s Obama’s fiscal year 2010 budget contains a proposal which gives the IRS the authority to draft regulations requiring tax return preparers who file more than 100 returns to e-file all individual, estate and trust returns. The 100-return threshold is defined as all returns filed by the preparer, which may include corporate, partnership, individual and other returns. For example, a preparer may file 40 corporate, 40 partnership and 21 individual returns on a yearly basis. Since the preparer files over 100 returns on a cumulative basis, he will be required to e-file all individual tax returns (as well as any estate, and trust returns that he might prepare). The proposal also would allow regulations requiring tax return preparers who file more than 100 returns (or any other person who files more than 250 returns) to e-file tax returns for individuals, estates or trusts.
(888) 557-4814 |
Estate Tax Developments In 2001, Congress enacted legislation designed to phase out the estate tax by 2010. Over these eight years the estate exemption has been increasing in increments, and is currently $3.5 million per person. Not only is the estate tax set to expire in 2010, but so is the rule that allows a step up in basis at death. That means that all would then come under a carryover basis regime that will be complex and difficult to implement. Wills and estate plans will all have to be redrafted if the repeal takes place beginning January 1, 2010, because Congress only repealed the estate tax for one year. If left alone, in 2011 the estate tax is reinstated at the levels that existed in 2001, meaning a $1million exemption and a 55 percent top rate. The current administration and Congress have stated that they do not want the estate tax to expire; however, neither the House nor Senate has taken any steps legislatively. Senate finance chair Max Baucus is supporting a permanent fix that encompasses much of a proposal
made by the AICPA. It would continue the $3.5 million exemption and would make it fully transferable between spouses, indexed for inflation along with an equivalent gift tax exemption, while maintaining step up in basis. House Ways and Means chairman Charles Rangle is proposing a one year extension of the current rules.
Tax Strategy Patents The patentability of tax planning methods is a growing concern among tax practitioners and taxpayers. In 1998, the U.S. Federal Circuit Court of Appeals, in State Street Bank & Trust v. Signature Financial Group, Inc., held that business methods could be patented. Since then, 78 patents for tax strategies have been granted and 132 patent applications for tax planning methods are pending as of August 2009. Patents for tax planning methods have already been granted in a variety of areas, including the use of financial products, charitable giving, estate and gift tax, pension plans, tax-deferred real estate exchanges and deferred

compensation. For example, one patent granted is for the process of computing and disclosing the federal income tax consequences involved in the conversion from a standard individual retirement account (IRA) to a Roth IRA. Many more tax planning method patents are expected to be issued, directly targeting average taxpayers in a host of areas including income tax minimization alternative minimum tax (AMT) minimization and income tax itemized deduction maximization. The AICPA believes that patents granted for tax planning methods 1) limit the ability of taxpayers to fully utilize interpretations of tax law intended by Congress; 2) may cause some taxpayers to pay more tax than Congress intended and may cause other taxpayers to pay more tax than others similarly situated; 3) complicate the provision of tax advice by professionals; 4) mislead taxpayers into believing that a patented strategy is valid under the tax law; and 5) preclude tax professionals from challenging the validity of tax planning method patents. The AICPA and SCACPA believe that patents for tax planning methods undermine the integrity, fairness, and administration of the tax system and are contrary to sound public policy. n Reference: The AICPA’s Tax Section provided information on federal issues.

PAYMENT CARD INDUSTRY (PCI) SECURITY STANDARDS COUNCIL The payment card industry has been working for years to increase the security of card data. At first, the card associations established their own policies and standards. In 2006 Visa Inc., MasterCard Worldwide,
South Carolina CPA Report w November/December 2009
American Express, Discover Financial Services and JCB International formed the PCI Security Standards Council and agreed to incorporate the resulting standards and certifications into their compliance programs. PCI DATA SECURITY STANDARD (DSS) The foundation of the Councils’ work is the Data Security Standard (DSS). Version 1.2.1 was released in July 2009. It is a very specific and detailed list of requirements for securing card holder data and contains hundreds of requirements, organized as follows: Build And Maintain A Secure Network Requirement 1: Install and maintain a firewall configuration to protect cardholder data. Requirement 2: Do not use vendorsupplied defaults for system passwords and other security parameters. Protect Cardholder Data Requirement 3: Protect stored cardholder data.

companies and individuals certified by the Council to perform required services for the higher level merchants.
Maintain a Vulnerability Management Program Requirement 5: Use and regularly update anti-virus software or programs. Requirement 6: Develop and maintain secure systems and applications.
APPLICABILITY Applicability of the standards to a particular entity can be confusing. The main rule states that “PCI DSS requirements are applicable if a Primary Account Number (PAN) is stored, processed, or transmitted. If a PAN is not stored, processed, or transmitted, PCI DSS requirements do not apply.� Generally, the deadlines for compliance with the DSS have passed, and all merchants who meet this rule should be compliant now. Estimates of actual compliance vary. The issuing associations direct the acquiring banks as to how they manage merchant compliance. An. PCI PAYMENT APPLICATION DATA SECURITY STANDARD (PA-DSS) This standard started as the Visa Inc. program known as Payment Application Best Practices. Its goal is to help software vendors and others develop secure payment applications that support compliance with the PCI DSS.

More hardware, software and management. 3) DSS 10.6 requires that log files for all components in the CHD system are kept for months and reviewed daily. This can be thousands of entries per day. More hardware, software and management. ALTERNATIVES FOR SMALL MERCHANTS Large merchants can justify implementing and maintaining compliant systems, but many smaller, Level 4 merchants can’t. The answer is to not store CHD electronically. In other words, don’t be a SAQ-D merchant. If you accept cards online, there are two basic ways to do it. Take PayPal as an example. PayPal offers “PayFlow Pro” and “PayFlow Link” as ways that a Web site can accept payment cards. With PayFlow Pro, buyers enter their card data on your Web site. Your system sends the data to PayPal for
South Carolina CPA Report w November/December 2009
processing, and PayPal sends the results of the transaction back to your system. Your system therefore stores CHD electronically, and you are a SAQ-D merchant. If you use PayFlow Link, the buyer is sent to a PayPal Web page for check out. All card data is entered into PayPal’s system, not yours. Your system still receives transaction results, but does not store CHD electronically. If you choose this method, you are now a SAQ-A merchant. If you are a face-to-face merchant like a retail store or a restaurant, it can be more complicated. Do you really need to store CHD electronically? There are several reasons to do so. One is as a service to the buyer, to make it easier to make a purchase on your Web site. Amazon’s “One Click Ordering” is an example. This feature is automatically enabled on your account the first time you place an order and enter your information. Some people love it. It can’t work without storing your CHD electronically. Even without the one click service, a lot of sites store your
(888) 557-4814 | an amount on the card. That POS system is storing your CHD. They do it to prevent you from walking out without paying. A very popular reason to store CHD is to handle charge backs. Frequently people will make a purchase and then claim they didn’t. But when asked how many charge backs he had, there were—depending on how you accept and process cards. BREAKING NEWS! This article mentions earlier that Level 4 validation requirements were set by the acquiring banks. Until recently, this has remained mostly a voluntary process of self assessment with no requirement to submit the forms to anyone. On August 1, 2009, BB&T
notified all of its merchant account holders that they had to complete and submit the self assessment forms, including an Attestation of Compliance by the Executive Officer. First National Merchant Services and First American Payment Systems have done the same thing. Voluntary selfassessment for the smallest merchants is quickly becoming a thing of the past. n

Valuing an Accounting Practice The members of SCACPA’s Business Valuation Task Force are sharing the expertise on valuing an accounting practice. Each task force member was asked this same question regarding pricing a new partner admission. Their individual responses are listed below. Staff Contact: Reva Brennan HOW DO ACCOUNTING FIRMS PRICE A NEW PARTNER ADMISSION? George DuRant, CPA/ABV/CFF, ASA, Columbia: Usually, one way or another, a new partner will pay for an interest via reduced earnings for some period of time. It is rare in my experience (but I have seen it) where a new partner is asked to buy-in based on some multiple of revenues and other factors. Growing and expanding firms seem more focused on retaining talent and receiving working capital contributions from new partners as opposed to “selling” an interest at pro rata firm market value. Non-growing firms admitting new partners are focused on old partner retirements, which are usually paid for on a retention basis over 2-5 years (out of earnings). James D. Ewart, CPA/ABV/CFF, CVA, Charleston: I believe what George is suggesting has roots in other industries such as physician practices, and has proven to be cost effective to the new partner and acceptable to the “old” partners because, all things being equal, income is not reduced in the first year. Additionally, how profits are divided could affect this approach. Finally, whether the “old” partners are selling a portion of their interest or the practice is expanding would impact this question. Don M. Hollerbach, CPA/ABV/ CFF, CFE, FCPA, CVA, CDFA, Charleston: A buy-in arrangement of some description is the norm in my experience, but I have seen a number of examples where the members of
18
a firm have the “eat what you kill” approach where there are revenue centers tied to the individual partners. In this arrangement, which is a form of cost sharing, the partners each maintain a client base, recognize revenue on an individual basis, pay for staff that are dedicated to their particular clients, allocate the overhead costs that are common to the partnership and share any value that is derived through cross-pollination of skill sets. New partners either bring a client base with them, and/or a specific skill set that adds value. Then they develop the client base to certain level while on staff, with a final transition to the process as defined above. The cost and revenue synergies created in this arrangement are of value to a partner, as opposed to a different business form such as a solo practice. Hendrikus E.J.M.L. van Bulck, MBA, Ph.D., CPA/ABV, Sumter: I have observed three general “models” for partner admissions: reduced earnings (as described by George DuRant), buyins (as described by Don Hollerbach) and mentorship. The size of the practice may be a determinant. Large, multi-partner accounting firms may be more concerned about preserving senior partners’ equity and retirement provisions. It is likely that these firms are fairly structured, and are more likely to have a formal recruitment plan, a buy-in plan or some form of “tenure track” (to borrow an academic term). Compared to solo practitioners, large firms may be able to distinguish
South Carolina CPA Report w November/December 2009
more clearly between the professional and corporate components of the firm’s goodwill. The corporate goodwill may be an important consideration in the buy-in formula. Conversely, the sole practitioner may bring along a young CPA not only to share the workload, but also to groom this individual to eventually take over the practice. This sometimes resembles the father-son relationship. As retirement approaches, the practitioner shifts more of the income and perhaps partnership interest to the junior CPA. Scott Hendrix, MBA, CPA, CVA, West Columbia: Admitting a new partner and how to price that admission generally is a function of two dimensions: the operating environment and the perceived value-drivers. For the most part, small to mid-size accounting firms will fall into one of three categories: sole practitioner, single-entity/multiplepartner, or multiple-entity/ multiplepartner. The value to be derived from a new partner may also span a broad array of possibilities. Obviously, a sole practitioner would most likely be looking to develop a partner to whom he or she could eventually sell the practice. Firms in the other two categories may be looking to replace a retiring partner, or seeking new and complementary talent to expand a niche or exploit a new and growing revenue stream. Notwithstanding, the commonly exercised historical imperative has been to admit new partners at a reduced earnings rate, with the difference between tenured average partner earnings and the reduced earnings representing a buy-in amount or a premium to the existing partners. Depending upon the size and profitability of the firm, this buy-in period may span multiple years, but generally not less than five years. n

Commentary On TIPRA 2005 and Roth Conversions by Neil Brown, MAcc, CPA, CFP SCACPA member since 1994
The current market environment may provide some sophisticated taxpayers a unique opportunity to pay taxes at today’s low rates on a depressed account value and capture tax free growth.
O
n January 1, 2010, thanks to TIPRA 2005, anyone with a tax-deferred retirement account that can be rolled over will be eligible to convert those assets to a Roth IRA. Now, higher income taxpayers will be able to take advantage of a conversion opportunity that was once limited to those with an AGI of less than $100,000. There is no better time to build a better future for your clients. Our role as advisors will be to determine if and how much to convert, and when to pay taxes. The factors to consider when converting to Roth include (but are not limited to) the taxpayer’s timeframe, source for payment of taxes and current vs. future tax rates. There is no certain set of circumstances where one should convert or not convert—instead, it will depend upon a client’s specific needs, desires and assumptions. The current market environment may provide some sophisticated taxpayers a unique opportunity to pay taxes at today’s low rates on a depressed account value and capture tax free growth. An IRA worth $100,000 in
20
2007 may now be worth $60,000. By converting the $60,000 retirement account to a Roth IRA, the taxpayer is locking in his tax liability at the lower amount. Should the $60,000 Roth IRA eventually recover its losses and grow back to $100,000, the taxpayer will avoid paying taxes on the $40,000 difference.
calculating MAGI for social security purposes, all taxable and taxexempt income and 50 percent of an individual’s social security benefits are included, but Roth IRA distributions are not. Therefore, a Roth IRA can prove to be a tax-friendly asset for managing the taxation of social security benefits.
Additionally, you can actually request a “mulligan” or a “do over” by performing a recharacterization, thereby reversing the original conversion back into a traditional IRA with no tax consequences. A Roth IRA can be recharac¬terized back into a traditional IRA up to the tax filing deadline—including extensions, whether extended or not. For example, if an investor converts a traditional IRA to a Roth IRA in February 2009, they will have until October 15, 2010 to decide whether to take the “doover.”
When paying taxes for the conversion, one could use assets from the IRA, or outside of the IRA. Using IRA assets to pay the tax liability results in a smaller Roth IRA balance, and any money not kept in the Roth conversion upon the rollover will be subject to an additional 10 percent penalty if under age 59 ½. If a taxpayer uses outside assets to pay the conversion tax, they are essentially allowing more assets to remain in the Roth IRA and effectively making a contribution to their retirement account.
A conversion could also help with the future taxation of Social Security benefits. Up to 85 percent of social security benefits are taxable if MAGI exceeds certain amounts. When
South Carolina CPA Report w November/December 2009
For 2010 only, a taxpayer who converts can include half of the conversion on the 2011 taxes and the balance on the 2012 taxes, thus slowing the tax payments. However, with the expected increase in tax rates
(888) 557-4814 |
in the coming years, most scenarios point to 100 percent inclusion in 2010 versus using the default spread. Of course, the spread could prove beneficial if one will be in lower future tax brackets due to reduced income or retirement. A Roth IRA will grow tax-free if all qualifications are met, and there are certain tax benefits. By utilizing a tax-free Roth IRA, retirees have more flexibility and control in managing their taxes. Most of us believe tax rates will be higher in the future. As such, now may be a great time to convert retirement assets to a Roth IRA. Many people currently consider our tax rate structure to be high, but historically we have seen top marginal tax rates as high as 50, 70 and 90 percent. Actually, for the last 50 years, there have been only a handful of years where the top tax rate was lower than we have now (1988-1992). By coordinating NOLs, loss carryovers and other tax items, a person can reduce or eliminate taxable income and thus the tax that would be associated with any Roth conversion. For instance, a business owner with taxable income of $75,000 and a NOL of $100,000 would have an adjusted gross income of negative $25,000. The business owner may wish to convert up to $25,000 of taxable retirement assets at little or no tax costs. Even small capital loss carryovers utilized against $3,000 of ordinary income would allow $3,000 to be converted with no tax increase if comparing to the tax due without the loss. The Roth conversion helps taxpayers realize favorable tax attributes, while paying little or no income taxes on the conversion. Now would be a great time to contact your clients with retirement accounts

Most of us believe tax rates will be higher in the future. As such, now may be a great time to convert retirement assets to a Roth IRA. and negative taxable income and work with them to rollover enough assets to push the taxable income to at least zero. Some clients want to pay no taxes and others would prefer to at least roll over some IRA assets in the 10 or 15 percent brackets. Again, this depends on the individual taxpayer, but we did so for many clients at the market bottoms in November 2008 and March 2009. Clients who want to leave a large estate to their heirs should consider this strategy as well. While all owned assets are included in the deceased’s estate, the Roth IRA could reduce estate tax as well as the future income tax of the beneficiary. First, the taxes paid for the conversion are no longer in the estate and the estate tax is higher than the income tax rate, and the heirs receive a tax free account they can stretch. While naming a trust as a beneficiary of a retirement account is a complex matter, a Roth conversion can help. Distributions from an IRA that are maintained in the trust are taxed at the trust tax rate, which reaches the 35 percent level quite quickly. With a Roth IRA, any distributions actually maintained in the trust are tax-free upon the initial distribution.
not. This tax-free feature can magnify the stretch provisions greatly. For example, assume a 70 year old with a $1,000,000 IRA would like to leave as much as possible to his 40 year old daughter at death. If he took only his required minimum distribution at age 70½, died at age 86, the account grew at 7 percent and the daughter stretched the traditional IRA, she would have received a total of $983,859 of after-tax distributions over her lifetime. However, had the Roth been converted prior to the father’s death, the daughter would have received a total of $1,492,920 of taxfree distributions, or 65 percent more, over her lifetime. Time, tax law and planning are moving quickly. For those advisors willing to provide great advice to their clients, now is the best time. If you simply want to do compliance work, there are many advisors who would love to add value to your former clients. We can no longer simply meet with our clients to do last minute tax planning or after the fact compliance work. We must add value—that is our goal. n

I
have now been a member of SCACPA for more than 20 years, but did not really take advantage of my membership until the last six years. By being more active in the organization, I have gotten much more out of my membership. For the past three years, I have been lucky enough to serve on SCACPA’s Technical Standards committee. Our group has 19 members and is chaired by Ellen Adkins. We meet via teleconference six to eight times a year and act as a technical resource for members, reviewing exposure drafts on technical standards and recommending a response. Additionally, the Committee plans the annual Accounting and Auditing Conference each December. Prior to joining the Technical Standards committee, I regularly attended the Accounting and Auditing Conference and was twice a speaker (for those who attended, I am sure it was a treat!). In all seriousness, I attended the conference to receive 12-16 hours of quality CPE and gain some insight into what other CPAs in the state are doing to meet some of the challenges we are all facing today. Our committee has planned another high quality CPE event to take place December 10-11, 2009. I am excited about the program and look forward
South Carolina CPA Report w November/December 2009
to the offerings that will be provided. I have heard a number of our speakers in the past, and they have the ability to make a seemingly boring topic interesting. In addition, I believe the topics we are offering provide real value to us in our jobs, whether we are in public or private practice. Each year that I have attended the conference, I can truly say that I have learned something that was immediately applicable to me at my job in industry. Whether the topic is fraud, technology or accounting rules, the subjects will apply to us in our roles as CPAs and trusted business advisors. As a member of the committee and the SCACPA board, I hope to see many of you at the conference. I always look forward to getting reacquainted with old friends and making new ones in the profession. I believe you will find the conference well worth your time, and you might just learn a thing or two!

What made you choose to become a CPA? During my senior year in high school, I decided to take an elective course in accounting. Debits and credits came naturally to me, and I really enjoyed the class. After further research, I determined that the accounting field offered many opportunities that interested me, which lead to my decision to become a CPA. What do you believe are the keys to a successful career? • Find your passion. It is easier to stay focused and meet deadlines when your work is your passion. • Never stop learning. Focus on your passion, but also spend quality time in all areas of life so that you are a well-rounded person. • Learn how to communicate effectively. • Set goals. Live with a vision, because if you aim for nothing you will hit it every time. What do you believe are the major concerns of CPAs today, and how can they be addressed? Accountants have many concerns on the horizon, from international accounting standards to compliance legislation and tax law changes. The current economic climate is likely to create another mandate for more legislative control over the accounting systems of businesses. Another more individual issue was reinforced by a CNN Money article ranked Certified

South Carolina CPA Report w November/December 2009
Public Accountants as the sixth best job in America. It was not the positive ranking but the quality of life ratings, however, that got my attention. The CPA profession received two average ratings in the categories of benefit to society and stress. I believe that each of us can reduce the work-related stress level by maintaining a healthy balance between our professional and personal lives. What have you accomplished that makes you proud to be a CPA? While I enjoy my day-to-day work experiences, I am most proud of participating each fall in various financial literacy programs. I receive a great deal of personal gratification if I can assist someone in developing a life skill that will make an impact on that person’s financial future. Whom do you admire most, and why? My wife, Tina, is a very hard worker and loving mother of our son and soon to be daughter, due in January. When I met her, she had a math degree from USC but was going back to school at night to be a MCSE (Microsoft Certified Systems Engineer) and CCNA (Cisco Certified Network Administrator). I have seen her study and work very hard to keep current with her profession. Tina is organized and always has a detailed list together before we go on vacation trips. She reads to our son every night before bed, and makes sure his school bags and lunch are packed. I am proud of her and admire her more than anyone I know. What advice do you have for young CPAs? Always look to understand “why” something was done. Don’t accept SALY (same as last year) as an answer. Investigate, review the final report or return to determine the “if and why” of any changes that a reviewer may have made. Reviewers do not always have a chance to send changes back to you. What do you do for fun? I spend time with my family going to football games, movies and just playing in the back yard with my son. I also enjoy running, hiking and gardening.
Ken also served on the following SCACPA committees: Web site Task Force (2007-2008); Information Technology Task Force (2003-2008; Chairman 2005-2006). He received the SCACPA President’s Award in 2003 and 2006.

Matthew Wilson's Weblog Artima Weblogs is a community of bloggers posting on a wide range of topics of interest to software developers. Artima.com Breaking Up The Monolith: coming at last Yesterday, after four years of vacillation and procrastination and occasional modification, I finally got the preface of my next book, Breaking Up The Monolith: Advanced C++ Design Without Compromise, into a form with which I'm happy. 8 pages in four years; at that rate the full book will take me 150 years! SourceForge shoots itself in the foot SourceForge.NET's new File Release manager takes computing productivity back to the days of the punched card reader, and it does it with Web 2.0! Just good service (?) A couple of plugs, with no ulterior motive, and a mildly philosophical musing. New Libraries coming ... Just a heads up about three new libraries, and improvements in two established ones, ... (and a thinly veiled hint at some help from any members of the C++ community who have time, and a desire to work with highly efficient, highly robust libraries.) Watch those spaces! Having the computer help you write and maintain your code is an essential facet of successful software development, and all good consultants will recommended that you follow suit. (Even if, sometimes, they forget to do so themselves ...) Breaking Up The Monolith: The End of the Procrastination! Having spent nearly two years "getting everything sorted" ready to write my next book, I've decided enough is enough. It starts TODAY! Development Management: Carthorse, Racehorse, or Wild Horse? Two radically different philosophies to the management of software developers. Which one do you favour? Why do Open Source?. To blog, or not to blog? After having spent the last 15 frustrating months of too-successful consulting that has stolen all my time for writing and most of my time for researching/open-source development, something's got to give! Is blogging the answer to my quandary? An exercise in compromise in class interface refinement. Attempting to find a compromise between the constraints of a facade that wraps a system API, the limitations of a limited namespace naming scheme, and a user wanting more expressiveness, revealed an interesting compromise in design. Monolith: Facts, Failures, Fallacies, Falsehoods and Furphies Looking for your best Fs, Fs, Fs, Fs and Fs regarding everyone's favourite (to use, or to moan about) language, C++. If you've got 'em, let me have 'em. The worst that can happen is you'll get a mention in the new book ... Back on board ... After a prolongued hiatus from public writing activities (articles, blogs, books) throughout 2006, I'm about to stage a comeback. For those with nothing to do with the next 120 seconds, here's an explanation of why, and what you can expect in the coming months. What is Documentation? Can we expect s/w engineers 2 be good at all facets? ... Contract Enforcement for humanity ... ? Should individual human beings, and humanity's institutions, adopt the principles of contract programming, and use contract enforcement in their own functioning? Would that lead to a better world?

When the system comes up, it saves the kernel and the core file, which can then be examined with adb(1):
# cd /var/crash/test# lsbounds unix.0 vmcore.0 # adb -k unix.0 vmcore.0physmem 1ece
The first step is to examine the stack to determine where the system was when it crashed:
$ccomplete_panic(0x0,0x1,0xf00b6c00,0x7d0,0xf00b6c00,0xe3) + 114 do_panic(0xf00be7ac,0xf0269750,0x4,0xb,0xb,0xf00b6c00) + 1c die(0x9,0xf0269704,0x4,0x80,0x1,0xf00be7ac) + 5c trap(0x9,0xf0269704,0x4,0x80,0x1,0xf02699d8) + 6b4
This stack trace is not helpful initially, as the ramdisk routines are not on the stack trace. However, there is a useful bit of information: the call to trap(). The first argument to trap() is the trap type. The second argument to trap() is a pointer to a regs structure containing the state of the registers at the time of the trap. See The SPARC Architecture Manual, Version 9 for more information.
0xf0269704$<regs0xf0269704: psr pc npc c0 ff2dd8b0 ff2dd8b4 0xf0269710: y g1 g2 g3 e0000000 ffffff98 8000000 ffffff80 0xf0269720: g4 g5 g6 g7 0 f02699d8 1 ff22c800 0xf0269730: o0 o1 o2 o3 f02697a0 ff080000 19000 ef709000 0xf0269740: o4 o5 o6 o7 8000 0 f0269750 7fffffff
Note that the program counter (pc) in the previous example was ff2dd8b0 when the trap occurred. The next step is to determine which routine it is in.
ff2dd8b0/ird_write+0x2c: ld [%o2 + 0x4], %o3
The pc corresponds to rd_write(), which is a routine in the ramdisk driver. The bug is in the ramdisk write routine, and occurs during an load (ld) instruction. This load instruction is dereferencing the value of o2+4, so the next step is to determine the value of o2.
Using the $r command to examine the registers is inappropriate because the registers have been reused in the trap routine. Instead, examine the value of o2 from the regs structure.
o2 has the value 19000 in the regs structure. Valid kernel addresses are constrained to be above KERNELBASE by the ABI, so this is probably a user address. The ramdisk does not deal with user addresses; consequently, the ramdisk write routine should not dereference an address below KERNELBASE.
To match the assembly language with the C code, the routine is disassembled up to the problem instruction. Each instruction is 4 bytes in size, so 2c/4 or 0xb additional instructions should be displayed:
rd_write,c/ird_write: rd_write: sethi %hi(0xfffffc00), %g1 add %g1, 0x398, %g1 ! ffffff98 save %sp, %g1, %sp st %i0, [%fp + 0x44] st %i1, [%fp + 0x48] st %i2, [%fp + 0x4c] ld [%fp + 0x44], %o0 call getminor nop st %o0, [%fp - 0x4] ld [%fp - 0x8], %o2 ld [%o2 + 0x4], %o3
The crash occurs a few instructions after a call to getminor(9F). If the ramdisk.c file is examined, the following lines stand out in rd_write:
int instance = getminor(dev); rd_devstate_t *rsp; if (uiop->uio_offset >= rsp->ramsize) return (EINVAL);
Notice that rsp is never initialized. This is the problem. It is fixed by including the correct call to ddi_get_soft_state(9F) (as the ramdisk driver uses the soft state routines to do state management):
int instance = getminor(dev); rd_devstate_t *rsp = ddi_get_soft_state(rd_state, instance); if (uiop->uio_offset >= rsp->ramsize) return (EINVAL);
Many data fault panics are the result of bad pointer references. | http://docs.oracle.com/cd/E19620-01/805-3024/debug-35/index.html | CC-MAIN-2014-52 | refinedweb | 687 | 65.86 |
My storage team and I focus on three of the most important aspects in any industry: customers, competitors and market trends. There is insight to gain and share in this role, so here is our take on Sun and Storage - Taylor Allis
Open Storage: Early Markets
As promised, below is a second White Paper on Open Storage. This second one addresses Open Storage market drivers and growth and is titled Open Storage Adoption. It can be downloaded here:
Again, I would like to thank Bruce Norikane, our Sr. Analyst, for
his help as well as our market research manager, Chris Ilg, for his forecasting work. And again, I'll use this blog to post the CliffsNotes for those short on time. Below I will cover the need for a new storage architectures and early target markets. In subsequent blogs I'll cover the Open Storage future market forecast, other vendor initiatives and customer case studies - early adopters who have used Open Storage to solve their critical business needs...
The Need for a New Storage Architecture
Bruce, mentioned above, made a profound statement during our Open Storage planning that ended up in the White Paper. He said, "Google and Amazon would not exist if they hadn’t built their own storage infrastructures." They certainly wouldn't exist in their current state. When they started, traditional storage architectures were too expensive and inflexible to support the business model they had in mind. So what did they do? They had to buy commodity components and developed their own software like the Google File System (GFS).
Certainly not everyone can build their own file system today. But the requirements that drove Google to build their own file system have done nothing but increased. Consider the following facts:
A new, more economic and scalable storage architecture is desperately needed - enter Open Storage...
Open Storage Growth Markets
Open Storage can (and will) compete with traditional storage architectures. But Open Storage won't "take over the world" overnight. Most likely the data center mix of open storage architectures vs. closed storage architectures will change over time and vary data center to data center (if history is our guide). But what markets will adopt sooner? What are the Open Storage "sweet spots"?
Web 2.0: I count Web 2.0 apps as applications delivered via the Web. Apps like blogs, wikis, podcasts, RSS feeds, mashups, and social-networking sites like MySpace, Facebook or SmugMug. Consider this:
And Web 2.0 apps are not just for up starts - Forrester surveyed 2,200 IT decision makers from traditional enterprises and found that 33% were planning on investing in Web 2.0 applications. Web 2.0 storage requirements differ from traditional storage requirements as well. They need massively scalable but low-cost systems. Web 2.0 users are even willing to trade high availability for lower costs. Everyone needs high scalability at lower costs - but the need in the Web 2.0 space is acute. Thus, Web 2.0 will be the key driver for Open Storage architectures.
HPC Storage: IDC estimates that HPC storage systems added about $3.9 billion to the 2006 server revenue total and will undergo faster annual growth than HPC servers. Maximizing I/O bandwidth and minimizing latency while scaling storage capacity is the top priority for HPC storage users. Because of this, data locality is an issue for many HPC implementations. What's data locality? HPC services provider Instrumental, Inc.explains: storage architecture is needed. The one thing that HPC storage deployments have in common is that they are all custom built. HPC users need direct access to their storage components and software along with the flexibility to swap components and customize software to optimize their storage. This is difficult to do with closed storage systems.
Additionally, parallel, shared or clustered file systems that leverage global namespace technologies are used in most HPC storage environments. This includes the HPC open source file systems Sun offers - like Lustre. In fact, Lustre is used in 15% of the top 500 supercomputers in the world and in six of the top 10 supercomputers.
Lastly, an additional top storage requirement in HPC is Hierarchal Storage Management (HSM) software (moving data from disk to tape).
Why? Just look at the massive amounts of data HPC applications generate. The San Diego Supercomputer Center states their earthquake simulations alone generate 47TB every week! By 2011, they expect archived data to grow to more than 100PB. HPC centers must leverage the economics of tape to store such massive amounts of data. Sun offers tape as well as open-source HSM software for disk-to-tape data migration - Sun's Storage Archive Manager (SAM) software.
To see the real-world benefits an open storage architecture can offer HPC customers, see the Texas Advanced Computing Center (TACC) implementation of Sun Constellation - aka Ranger.
Server Virtualization: Open storage introduces more flexibility and consolidation benefits to the server-virtualization market. This added functionality can be realized in two ways:
Storage users can now consolidate three servers and a storage appliance onto a single server. In a closed architecture, storage software cannot be separated from the hardware.
In the second scenario, users can use an open storage server, such as the Sun Fire X4500, as a storage target or shared appliance. What’s unique is that users can repurpose their storage appliance as their needs change. For example, customers can repurpose the same Sun Fire X4500 into a NAS device, a Virtual Tape Library (VTL) or a data replication appliance without buying more hardware. Now that's investment protection!
In the following diagram, a customer has taken a Sun Fire X4500 server running Linux-based VTL software and has repurposed it into a remote replication appliance by leveraging server virtualization and open source Sun StorageTek Availability Suite software.
Sever Virtualization and Open Storage can deliver better investment protection and significant cost and consolidation advantages ...

Founder @Ruksack - Developer. Tinkerer. Entrepreneur.
It was infatuation at first sight with Crystal, a programming language built for humans and computers. What a noble cause. Having been a fan of the beauty of the Ruby syntax, the promise of Ruby-like syntax with the speed of C was intriguing — life-altering, even.
Since that day, I’ve been closely following the progress of Crystal and today, I will make a case for why you should care. It’s quite honestly one of the most exciting languages with promise for great potential.
Before we get into it, keep in mind that Crystal is not yet ready for production, but you can still find many projects already using it — like this version of Sidekiq, written in Crystal.
So, why should anyone care about yet another programming language? Well, because Crystal has combined a concoction of incredibly compelling ingredients that you won’t find in many other languages.
One of the most appealing things about Crystal is the clean and readable Ruby-like syntax. The creators of the language understood the appeal of Ruby as one of the most visually appealing languages and they took it as the inspiration for Crystal.
So, if you are coming from the Ruby world, transitioning to Crystal is going to be straightforward. Most of the time, you will be able to run Ruby code directly in Crystal, or run Crystal programs within a Ruby shell.
To top it all off, you can even use Ruby syntax highlighting with Crystal. Similar to most interpreted languages, Crystal will let you build your wildest imaginations in a few lines of code.
Crystal is a statically compiled language built on top of the revered LLVM framework and can hold its own against the likes of C, C++, and Rust.
Just let that sink in a little bit… The development speed of Ruby syntax with speeds matching C…
It’s incredibly compelling and hopefully has you as excited as I was when I first heard that claim. Don’t believe me? Just check out some of the latest benchmarks; this benchmark and this benchmark.
If a part of your application or algorithm requires extreme performance, one strategy is to offload the functionality to a C extension or library.
With Crystal, binding to existing C libraries or your own C libraries can be done without writing a single line of C code.
Consider a quick example of a C library hello.c that we can build using the GCC compiler gcc -c hello.c -o hello.o.
#include <stdio.h> void hello(const char * name){ printf("Hello %s!\n", name); }
#hello.cr @[Link(ldflags: "#{__DIR__}/hello.o")] lib Say fun hello(name : LibC::Char*) : Void end Say.hello("your name")
After building the binary, you can easily link the binary using Link and define the lib declaration which groups the functions and types belonging to that library — followed by calling your function. Voila!
Crystal is a statically-typed language, allowing it to rule out many type-related bugs at compile-time and setting the stage for optimizations that would not be possible in dynamically-typed languages like Ruby or Python.
This directly contributes to the performance of Crystal and what’s even more impressive is that the compiler in Crystal only requires you to explicitly specify types in case of ambiguity — the rest of the time you can work with it like any dynamic language.
Macros are a way to modify the abstract syntax tree created during a programming language’s tokenizing and parsing phase, allowing us to add methods at compile time or create and modify classes.
The main advantage of this is speed — as you save a lot of time spent by the compiler for invoking/calling functions.
Crystal lets you utilize the majority of the language when it comes to writing macros, which means you can do crazy wizardry that normally would be unheard of in a statically-compiled language.
Any comparison isn’t complete without talking about available web frameworks in the language and if you’ve already fallen in love with the likes of Rails and Phoenix — you’ll feel right at home with Crystal’s web framework Amber.
It was designed from the ground up to follow Rails but is obviously an order of magnitude faster than Rails — with load times in microseconds not milliseconds.
If you fall under the camp of Sinatra lovers, fear not because you’ve got the simplicity of the Kemal framework.
Did I mention that Crystal’s built-in HTTP server has been able to handle over 2 million requests per second in benchmark testing? And most of the frameworks also deliver sub-millisecond response times for web applications.
Crystal currently supports concurrency as a first-class citizen, while parallelism is making its way up the ranks — you can read about its progress on the Crystal website.
Concurrency is supported in Crystal using Fibers — a lighter-weight version of an operating system thread. Unlike threads, which are pre-emptive, Fibers explicitly tell the runtime scheduler when to switch context. This helps Crystal avoid unnecessary context switching.
If you want to add concurrency, you’ll find the spawn method in Crystal similar to the use of go-routines in Go — which I am personally a huge fan of.
# Simple example spawn do sleep 5.seconds end
Crystal also has support for channels inspired by CSP that allow communicating data between fibers without sharing memory and having to worry about locks or semaphores.
As software engineers, we are always making tradeoffs when choosing a programming language or framework and like any language, Crystal isn’t the answer to all your prayers and comes with its own limitations.
- Crystal is still relatively young and immature which leads to a lack of community and packages at this particular point in time.
- This also results in a scarcity of development tools available even though they are readily becoming available.
- If you are aiming to do something incredibly specific, you’ll have trouble finding documentation but this just means we have an opportunity to be the first adopters and hack together cool projects.
- Even though concurrency is built into Crystal, work is still being done on parallelism being a first-class citizen.
- Due to the pre-production status of the language, there is a possibility of breaking changes until v1.0 is reached.
- It also doesn’t have great Windows compatibility but quite honestly, that’s not a negative for me.
It might still be a while until Crystal is ready for production use, with great tools and a thriving community behind it. But it’s comforting to know that a wonderful language like Crystal is in the works behind the scenes.
Looking at all the features that Crystal brings together, it is deserving of a lot of attention and popularity. If I’ve piqued your interest, I would encourage you to check out Crystal and make your own decision.
In the meanwhile, I will continue to evangelize Crystal and keep a keen eye on its progress.

So IMO this workaround has no merit... It's a known deficiency in gcc. The gcc manual gives some examples of problem situations, such as: int save_y; if (change_y) save_y = y, y = new_y; ... if (change_y) y = save_y; gcc isn't smart enough to figure out that save_y will only ever be used if it was also initialized. Even if gcc _could_ handle that case, it's easy to make it a lot harder: int save_y; if (v1) save_y = y, y = new_y; ... if (v2) y = save_y; and then have the relationship between v1 and v2 be complex, or expressed in a different translation unit. gcc does not have an attribute similar to __unused__ to mark these cases. I have no idea why not, as it would seem to be a perfect place for one. Instead the usual "solution" is to self-initialize. In fact gcc intentionally does _not_ warn about self initialization unless you enable -Winit-self, presumably for exactly this reason. -Dave Dodge | http://ffmpeg.org/pipermail/ffmpeg-devel/2007-September/039398.html | CC-MAIN-2016-44 | refinedweb | 286 | 70.02 |
Just to make my question clear, first I have a short explanation about my task. I would appreciate if you tell me any comment for each step of my work, since i am beginner in this stuff.
I want to render an image for display on a multilayer display, based on the z values of the picture. I found Blender as a rendering tool (it means i am completely new
So, for extracting z value in Blender, I opened a .blender image, clicked on "Render" menu, then wrote a short script of Python, like:
import bgl
zbuf = bgl.Buffer(bgl.GL_FLOAT, [100*100])
bgl.glReadPixels(150, 140, 100, 100, bgl.GL_DEPTH_COMPONENT, bgl.GL_FLOAT, zbuf)
But I got for all z values 1.0. I know almost nothing about working with Blender. Is there something I am missing?
And, is the process that i am going to do with the whole idea correct or achievable?

Greetings--I'm testing in the 8120 Simulator, using the 4.3 JDE.
I've written code to pull up a MainScreen in the foreground when the simulator starts (this is a UI that will generally be used in the simulator only):
invokeLater(new Runnable() {
public void run() {
pushGlobalScreen(new TestUI(), 1, UiEngine.GLOBAL_MODAL);
}
});
I also set the app to "auto-run on startup" from the Eclipse project properties.I also set the app to "auto-run on startup" from the Eclipse project properties.
I tried the pushGlobalScreen without running it in the context of invokeLater; it generated a runtime exception. I also tried it in the context of a synchronized(Application.getEventLock()) block; same result.
In any case, it sort of works--it displays my UI fine. But almost immediately thereafter, the simulator (not my app) looks like it generates a data receive and then a send, and shows the little up/down arrows on the UI. As a result, this whites out the display UI. If I click the trackball, my app repaints, mostly (minus one separator). I'm presuming the interrupting UI has higher priority.
How do I ensure that my app stays in the foreground, or at least repaints after being obscured?
I tried implementing the following in my MainScreen subclass:
protected void onObscured(){
// Screen activeScreen = UiApplication.getUiApplication().getActiveScreen()
;;
// activeScreen.getUiEngine().suspendPainting(true);
UiApplication.getApplication().requestForeground()
;;
}
... both with and without the commented-out code, but neither had any visible effect.
Many thanks for any recommendations!
Jeff
Solved! Go to Solution.

The repaint should occur automatically. But I think you may be trying to display your GUI before the BlackBerry is prepared to do so. Please ensure that you check the ApplicationManager.inStartup method to ensure that the startup process is complete before you display your GUI.
If this isn't the case, please post a larger code sample that shows how you are displaying the screen.
08-01-2008 12:08 AM
Greetings Mark,
Many thanks for the response! I tried putting in a sleep loop (first outside, then within the invokeLater), but that hung.
So, in response to your suggestion, I started stripping down the code to post as small an example as possible. In doing so, I discovered that I do not need to do a pushGlobalScreen. Instead, a simple pushScreen works as long as the MainScreen implements the method onObscured:
import net.rim.device.api.ui.*; public class AgentApp extends UiApplication { public static final long guidName = 0x7bad99728b25ff48L; public static void main(String args[]) { AgentApp app = new AgentApp(); app.execute(); app.enterEventDispatcher(); } private void execute() { invokeLater(new Runnable() { public void run() { pushScreen(new TestApp()); } }); } } import net.rim.device.api.system.*; import net.rim.device.api.ui.*; import net.rim.device.api.ui.component.*; import net.rim.device.api.ui.container.*; public class TestApp extends MainScreen { public TestApp() { // ... } protected void onObscured() { UiApplication.getApplication().requestForeground()
; } // ... }; } // ... }
Thanks again,

PRESIDENT TRUMAN IS STILL FOR PALESTINE Washington (JTA)President Truman qualified his recent statement on Palestine in a conference in the White House with Rep. Adolph J. Sabath, the latter told the Jewish Telegraphic Agency. Representative Sabath said that the President assured him of his deep interest in the welfare of the Jewish people and that he was trying to secure fair, just and equitable treatment for them everywhere in the world. Such fair treatment, when it prevails, the President told Rep. Sabath, might be expected to lessen the pressure for Jewish emigration to Palestine and would make unnecessary the tremendous effort to transport large numbers there. Rep. Sabath also declared that the President had expressed concern over the trouble in store by reason of Arab opposition to Jewish immigration to Palestine, but at the same time, he is still trying to enlarge opportunities for immigration there. "The President is working at it both ways," Sabath said. Asked whether there had been any Arab communication to the President after his recent statement on Palestine, Rep. Sabath said he did not know, but he assumed that the President knew how the Arabs felt.

Asked whether he considered that the charter empowered the United Nations to intervene when some state embarked, for example, on persecution of Jews under the pretext that it was an internal matter, the Prime Minister replied affirmatively. Earlier, Atlee refused to give the Commons any details on his consultations at Potsdam with President Truman regarding the Palestine problem. He also declined to answer a question as to whether he would consider the establishment of a small impartial Antlo-American commission to examine on the spot the Palestine question and present a joint report to the respective governments. "I am at present not in a position to make any statement on this matter," he said. The question was put to Attlee by Capt. Marples, one of the new members of the House. At the same time, the Prime Minister promised to make a statement on the Palestine issue "as soon as we have time to consider the matter." This promise was made after a question by Lord Winterton, who is known for his proArab sentiments. Buy War Bonds and Stamps to help preserve Democracy. PAINTING GLASS INSTALLED V. K.

BLUMENTHAL RABBIS MAKE YEARLY j HARRISON DISCLOSES PILGRIMMAGE NEEDS OF HBUbttt EDITOR'S NOTD: We have re,, Ived a minibcr <>f Inquiries from our readers, contused by PUDllcHy Bppearing In the Jewish "orldlan concerning a Denver Institution that refused to accept a Federation nil. Minion. The institution concerned has no connection with the National Home for Jewish hlldren, nt Denver, which has a local, active chapter. The following article tells of some of the work of this Institution which Is a participating nKency nf the Greater Miami Jewish redi ration. Rosh Hashonah this year brings the hope for a new birth of freedom for all the peoples of the world. With the advent of the Jewish Now Year, the National Home for Jewish Children is rededicating itself to the guarantee of a new birth of freedom for a special portion of American Jewish youth freedom from the misery and suffering brought on by acute asthma and other allergic diseases. For thirty-eight years the Home has concerned itself with the care of underprivileged children of tuberculous parents. In recent years it has taken on the additional service of saving and rehabilitating the allergy-afflicted children for whom all medical treatment proved ineffective in their home environments throughout the country. Nestled at the foot of the snow-capped peaks of the Rocky Mountains, in the high, dry climate of Denver, the National Home is the only one of its kind in the country. The Home opens its doors to children whose families cannot afford the extensive and costly private care necessary to alleviate the suffering of their youngsters. When competent medical opinion recommends a change in climate and environment for such children. the Home admits them after an intensive medical and social studv. There the child remains until" it has been restored to normal health, or has sufficient!) recovered to make possible return to its own home. Children whose pale, anxious faces and appealing wide eyes once tola the tragic story of a struggle lor each gasp of breath: youngsters who saw their faith and hope crushed as medical treatment failed to help them: children who. in physical and resultant emotional and mental distress. have known nothing but pain and struggle are led back to healthy and happy lives through the pioneering work being done at the Home. These children come from all parts of the country, from New York to California, from Michi! gan to Texas. They remain at j the Home a year or two, or longer, until there is satisfactory recovery from the illness. In a comparatively normal environ! ment, and sharing the com1 panionship of other children, the asthmatic child is under expert medical supervision and is cared for bv a staff trained in child welfare. During its stay, periodic examinations are made and I full reports given to the refering physicians and hospital clinics. The National Home has a modern, well-equipped infirmary where children requiring bed care arc attended by registered nurses under the superviOf the attending physicians. The children are housed in attractively furnished congregate cottages. Each child is afforded the privacy of an individual bedroom. Food of the highest quality is carefully prepared in modThe Rabbinical Association of Greater Miami, announces ihat lhe annual pilgrimage to local cemeteries will an place Sunday, September 16th. The schedule nounced. will be anern kitchens and special diets are given when prescribed by the physicians, In addition to the intensive preparation made prior to the child's admission to the Home, an equally thorough after-care program is carried out upon the return of the child to its family. The purpose of this program is to make certain that the child will continue to enjoy its newhealth in the very Washington (JTA) Earl G. Harrison, United States representative on the Inter-Governmental Committee on Refugees, who recently returned from a six-weeks presidential mission to Europe to inquire into the condition and needs of stateless and non-repatriable persons, including 100,000 Jews of all nationalities in Germany, presented a detailed report to President Truman, recommending concrete improvements in their situation. Declaring that the President manifested real interest in the report, Mr. Harrison said that the President will take whatever steps are necessary to bring about an improved situation. The Inter-Governmental Committee on Refugees has not yet lv restored health in environment which originally bt , un to f unc tion on any broad was a factor contributing to tl 11 ba £ js Harr j son stated. While in Germany, Harrison .. I visited a number of camps houschild's illness. Trained social workers help educate the parneglect ethical and religious education under the guidance of expert teachers. The children participate in the community life by attending the local schools and in joining in communal recreations. The National Home's record of achievement fully shows the effectiveness or its Health program. This program has proved itself i i be a solution to many a perpersons, he stated. "There are no more Jews, because they killed them, and I saw the places where that was accomplished, at Dachau, Belsen and other concentration camps." Inquiry into the desires of the displaced Jews as to their future destination revealed a definite trend, Harrison declared, but declined to name this destination which, he said, is named in his report to the President.

York city, and chief consultant physician of the National Home states: "The National Home for Jewish Children at Denver, through a fortuitous combination of climate and environment, has brought remarkable relief to many children suffering from chronic bronchial asthma and other allergic respiratory diseases. The Home has amply demonstrated that complete recovery from asthma can occur in those cases heretofore regarded as hopeless. It has the most ideal setup I ever saw; the only place of its kind in America for care of asthmatic children."" Many little sufferers quickly become new human beings at the National Home. They arcgiven a chance to grow again and to enjoy the natural birthright of a happy childhood.

It is the strongly considered opinion of the members of the Snack Bar Committee that there is no more important phase of the army and navy work of the Jewish Welfare Board in Miami which has aroused more favorable comments, not only on the part of the military and naval personnel but also the general public. At this particular time, because of the vacation period there is a shortage of volunteers who play the most important role in carrying on the work of the Snack Bar. A plea is being made for more volunteers so that the vital service of the Snack Bar may continue to draw not Mr. and Mrs. Benpamin Shulman, 528 Lincoln Road, Miami Beach, received a very interesting letter from their daughter, Lt. Florence Shulman, now with the army of occupation in Germany. Lt. Shulman is an officer in the WACS and has been in service three years. She is now attached to the Seventh Army. Excerpts from her letter of interest to our readers follow: "This trying to get a letter written is almost an impossibility but things are bound to settle dqwn to normalcy one of these days. It seems a lifetime since I left the good old U.S.A., but believe me, with all the wonderful experiences I've had, this tops anything imaginable and being with the army of occupation is going to be rather pleasant living. I was brought over here to be a P. A., which is a general's aid, but after being around Com Z Hqrs. in Paris for a few days, I decided that I wanted no part of it. There is so much confusion there that you wonder how we ever won the war and then when you get with a fighting outfit like the one I'm now with, you can easily understand why. After wearing that Air Corps patch for 20 months, I'm mighty proud to give it up to don that of the Seventh Army, which is the best outfit going. These boys are the ones who landed at Casablanca, came through the Tunisian campaign, Salerno, Sicily, the Anzio beachhead and on up to Germanythey were General Patton's original outfitbut he's only the plaudits of the local commanding officers but the apnow~wfth~Third Army in Munich" probation of the leaders in civilian and military life throughout the country. Those who desire to offer their Most of these boys have been together for about three years, and it's just one big happy familyour colonel is just as much services are requested to phone | one 0 f the GI's as the rest of Mr. Calvin Reich, manager of the Snack Bar at 58-2171 and arrange for an interview. Lt. I. S. Korach, USNR, former Miami Beach architect, has just returned from service as air combat intelligence officer with the last carrier task force. He was on board the carrier Yorktown in raids on Tokyo, Iwo Jima, Okinawa and the Japanese islands. He was with the Marines in the initial attack and capture of Guadalcanal in 1942, and shares a Presidential Unit Citation and a citation from Admiral Halsey for carrier work. Morris L. Haimowitz of Miami Beach, an officer assigned to the control office of the Hawaiian air depot, has been promoted to first lieutenant. Lt. Haimowitz' parents, Mr. and Mrs. Samuel Haimowitz, live at 937 Washington Avenue. Before he entered the army in July, 1942, Lt. Haimowitz was employed as a sociologist at the University of Florida. Word has been received by Mr. and Mrs. Jack Bernstein that their son Roy has been made a chief petty officer. He has been in the armed service three years and is now in Okinawa awaiting shipment to the States. Their daughter, Irma, has learned that her fiancee, Sherman Freedman, has been made a lieutenant (j.g.). Lieut. Freedman, who is now in New Orleans, is the son of Mr. and Mrs. Maurice Freedman, of Baltimore. Pfc. Allan Wolff, son of Mr. and Mrs. Nathan Wolff, 1434 Jefferson Avenue, recently visited his parents while en route from Fort Bragg, N. C, to Fort Sill, Okla., for advanced radio study in field artillery. Capl. Marico S. Weintraub, military police officer with Gen. Patton's Third Army, has been awarded the Bronze Star for exceptionally meritorious service in the Ardennes and Remagen sector. The award was given him m Nuernburg, Germany, where he served as provost marshal, tie was commended for setting up traffic co-ordination and dispensing supplies with such efficency that swiftly moving troops proceeded with smoothness at maximum speed. A native Miamian, Captain Weintraub entered service in January, 11942, and has been overseas for 16 months. He holds a unit citation presented for service at the Remagen Bridgehead. He attended the University of Florida for five years and when discharged will return for his degree in architecture. the boys and it's wonderful being with some real men again. Most of the boys in Paris have "gone Paris" in a big wayand indulge in "L'amour toujour L'amour" all the time. Although fraternization is permitted here in Germany, it hasn't gotten underway in full force yetand some of the fellows, as much as they may want to go out with German girls, won't do it. It's hard to believe that these people could have been such ardent Nazisthey are more like the Americans than any other people in Europe, the greater percentage of them speak English they are a very clean people, and the girls look just like the gals back home. France is the dirtiest place imaginable, and prices are beyond my means. Here in Germany, our money goes a long wayyou actually feel ashamed at paying so little for what you get, when you pay for it at all. Our boys have very taking ways, and you just take most of what you want if you can get the permission of the military government. You can have an entire week's laundry done here for one mark, which is 10 centsin Paris, it runs about $25 for one week's laundry, and at those prices, its simpler to go dirty. While I was in Paris, I visited the Louvre, Versailles and all the sights of Paris itself. Now as to my setupI'm located in Heidelberg, one of the most beautiful spots in Germany. It wasn't bombed at all, since it was of no value militaristically or industrially, being merely the home of the university, and the surrounding mountains hold some gorgeous chalets and castles, which are now occupied by our generals and colonels. I left Paris by ATC last Monday morning, en route for Munich, but since I was unable to discover the exact whereabouts of the Seventh Army I got off at Frankfort, where SHAAF Hqrs. is located to do a little investigating. The army had moved from Augsberg to Heidelberg over the week-endso it was a good thing my trip to Munich was intercepted because I wouldn't have found my army there. I connected with three officers bound for Hqrs. in a jeep and off we went. Believe me, our Air Force didn't leave much standing in GermanyFranfort and Mannheim are completely demolishedit's unbelievable some towns don't have a single building remaining standing. We're only about 10 miles from Dachau, but I have no desire to visit that spot. There are nine WAC officers here now, the first women ever to be assigned to the Seventh Army, and believe me, they are mighty glad to have us. I'm going to replace a major, who will be able to return home just as soon as I'm able to take over. My job is that of administrative officer in G-4 and a grander bunch of officers and EM you won't find anywhere. They confiscated an apartment house for uswe have three apartments, with three gals in each apartment. As yet, we haven't even started to settle down, but hope to acquire all the necessary household items as time goes on. We have a beautiful baby grand piano in our apartment, and the makings of a very comfortable homeit will just take a little time. We have taken over the most beautiful hotels as our messesand the food isn't too bad, except that I can't get very enthusiastic over German cooking. They put cream sauces on everything, even steak. There are three messesone for Lts., one for captainsand one for the field grade officers. Fortunately, we gals can eat at our own mess or be guests of other officers at theirs, so I've been getting some variety. They have just opened a new officer's club up in the mountains, which is just a dream place. You should see the cars the officers ride around inone of the officers has annexed Goering's car with its armored body and glass about one inch thick the car weighs several tons. They drive around in these enormous Horschs, Mercedes, besides the American made cars. No civilians are permitted to have cars, so the army has taken every available car, and we've been fairing very well. The University of Heidelberg is getting ready to reopen, so we're hoping to be able to take courses there when that happens. They are going to make things as pleasant as possible for the boys who stay on with the army of occupationand after what they have been through they deserve the best. After three years in the army I've once again run across some real gentlemen. These boys have been on the frontlines so long, living the most rugged sort of existence and they are so afraid they will do something wrong. These boys have been dreaming about the gals back home so idealistically the past few years that they are afraid to touch you for fear something will be spolied. I've had more real honest-to-goodness fun these past few days than I've had in years, and never have met a grander bunch of menas honorable as the day is long, and the straightest shooters going. Just to be able to talk to a gal that talks their language is a bit of heaven." Pfc. Stanley O. Goodman, son of Mr. and Mrs. Samuel Goodman, of 1010 Pennsylvania Avenue, Miami Beach, recently completed a four-week term at the Mediterranean theater's university study center, Florence, Italy. Overseas 17 months Goodman wears the Good Conduct ribbon and the Mediterranean theater ribbon with three battle participation stars, and the combat infantryman's badge. Maj. Leonard H. Finn, whose wife, Mrs. Beatrice Shaff Finn, lives at 319 N. E. 25th Street, may wear the meritorious service unit insignia awarded the 25th Army Air Forces base unit at Robins Field, Ga. Sgt. Waller Dansky, former football star at the University of Miami, is now stationed as civil engineer with the Army Air Forces in Manila. He has been overseas 19 months in the Netherlands, East Indies and New Guinea. Promotion of Edward S. Roth, 1915 S. W. Third Avenue, to major has been announced by Persian Gulf Command headquarters. Assistant chief of the Armv Exchange Branch of PCC headquarters, Maj. Roth has served in the once-vital supply line to Soviet Russia since Jan. 13, 1943. He is a graduated of the University of Florida and entered the army July 1, 1941. Lt. Lawrence Singer, son of Mr. and Mrs. W. D. Singer, of this city, is now enroute to the Pacific. During his stay on the coast he spent most of his time with Chaplain Colman A. Zwitman, of Miami, who is also reported on the way to the Pacific.

It reached a point where Ben-Gurion, as chairman of the world Zionist executive, got up at the conference and declared that Weizmann docs not express the views of the executive This explains, perhaps, why Dr. Weizmann left for a vacation in Scotland just a day before the closing of the conference without delivering the usual closing address, which was delivered by Ben-Gurion. Russian Scene The increased anti-Soviet feelings which are now growing in England as displayed by Churchill and Foreign Secretary Bcvin in their speeches last week in the House of Commons are provoking in Moscow among other thingsintensified anti-Zionist feelings The Kremlin is taking the old line that Zionism is a tool of British imperialism, especially since it has become clear .that a Jewish State cannot exist in Palestine without the aid of Britain President Truman's announcement that Stalin was not consulted at Potsdam with regard to Palestine because he cannot do anything anyway, also did much % to contribute to Russia's renewed anti-Zionist feelings ProSoviet Jewish groups in America intend to discuss with Soviet Ambassador Gromyko in Washington the desirability of opening Biro-Bidjan to large-scale Jewish immigration from liberated European countries Originally, Moscow did not want to admit Jews from abroad to Biro-Bidjan because Russia expected a war with Japan, and Biro-Bidjan is situated right on the Russo-Manchurian frontier With the occupation of Manchuko by the Red Army, Biro-Bidjan is now very far from the Japanese border There is also no fear any longer that Japan will attack Russia for many years Hence some believe that Stalin may agree to admit many thousands of stateless European Jews to BiroBidjan Especially the thousands of homeless Jews now living in the Russian-occupied zone of Germany Also Jews who may no longer desire to live in Poland, Hungary, and Slovakia (((vantages of a Dade Federal Mortgage Consult US on Financing or Refinancing Your Home LOW RATES 1 nil.],Interest charges on d balances* EASY PAYMENTS % I'-. including Interest Principal, need be no more present monthly rental, 1 In many cases are less li> sent monthly rental.

PRESIDENT where anti-Semitism is still rampant Large scale settlement in Biro-Bidjan, it is argued could be Stalin's contribution to solution of the Jewish problem in Europe ... It is along these lines that discussions will be held in Washington with Soviet diplomatic representatives War and Peace A war novel which will be read long after the war is over is "The Journey Home" by Zelda Popkin, who for many years was connected with the Joint Distribution Committee Published by Lippincott on the eve of the end of the war, the book deals with the feelings of a man in the armed forces when he returns to the United States from "over there" bitter, tired and suspicious ... He finds himself suddenly after the train on which he travels from Miami to his home in New York crashes near the end of the trip .... Normal, human feelings awaken in him when he discovers that he is able to help people during the train wreck The author cleverly selected a Miami-New York crowded train as the scene of her action, since twenty-four hours of travel on a train bring people closer together The variety of passengers on the train, their conversations, the different classes to which they belong form a good pattern of war-time America ... It is to this America that many a soldier returns from overseas, hating everything and resenting sympathy ... He finds love at the end of the journey, after thinking that love is nothing but an old-fashioned word which does not belong in the world of today Mrs. Popkin is the author of a number of successful mystery stories "The Journey Home" is her first novel and it is the kind of a novel of absorbing interest that one wants to read from the beginning to the very end Domestic Issues With the war over, Congress will soon be faced with the problem of what to do with the 211,000 visas to which Germans are entitled yearly under the American immigration quota It is obvious that this country can not afford to admit 29,000 people who for the last twelve years have been indoctrinated with Nazi propaganda ... It is these very same people that the Allies are now trying to keep isolated for years of "re-education" in the democratic way of life Therefore, under dis cussion is a proposal to bar anyone from Germany for the next ten years, except immigrants who can prove that they were anti-Nazis Jews would naturally fall into the latter category Congress will also be asked to allot the German immigration visas to the thousands of refugees who were admitted to this country on "visitors' visas" and who must now return to their native lands from where they fled during the Nazi regime These suggestions, if accepted, would enable the refugees to change their "temporary stay" in the United States to permanent residence as full-fledged immigrants There is also a suggestion that the" German quota for the next five years be divided among Poland, Hungary, Rumania, Greece, Czechoslovakia and Yugoslavia Congress will have to decide whether the immigration quota for Germany should be kept, cut, ended or restricted, and representatives of Jewish I organizations will be asked to testify at special hearings It is obvious that if Germans were admitted under the immigration quota, the Nazi underground movement would flood the United States with spies in an attempt to get hold of the secrets of the atom bomb and other military secrets which might prove useful to them in starting a new devastating war Even children from Germany are not a desirable element in this country, since a study made by the American Military Government established that the children in the Reich are even more pro-Nazi than the adults who understand that Nazism is defeated forever HEADS B'NAI B'RITH AMERICANISM DEPARTMENT Vy T-'-'-% % % ?

FRIDAY, AUGUST 31. 1945 'Jewistifkric/nr PAGE ELEVEN THE JEWISH QUIZ BOX By Rabbi Samuel J. Fox (Copyright, 1945, J. T. A.) QUESTION: What are "Selichos? ANSWER: The colloquial expression "Selichos" refers to I penitential prayers that are offered at different times for the gake of admission of guilt and the solicitation of divine forgiveness. In the amalgamation of Jewish prayers there are many sorts of prayers. The word "Selichoh" literally translated means "forgiveness." The Taanaitic literature usually describes the origin of the "Selichoth" prayers as a method described to King David through divine Revelation. David is said to have become alarmed at the trials and tribulations of his people and was seeking some means of forgiveness for their sins when the Almighty advised him for REST CONVALESCENCl ICHRONICCASEJ -RqyPark Health Resort ask for KOSHER ZION PRODUCTS at your LOCAL DELICATESSEN THIS LABEL Insures Your Health U.

W. 7th Avenue PHONE 2-6141 to gather his people together whenever a crucial moment would arise and to offer prayers of repentance and forgiveness QUESTION: Why arc Selichos Bald before Rosh Hashana (New ANSWER: The New Year being a day of judgment, is to be considered a crucial period in the life of men. It was therefore deemed advisable to recite special penitential prayers before the New Year begins as well as in the New Year's service and for ten days following, including the Day of Atonement. Furthermore, the rabbis ordered every man to consider himself as a sacrifice (since personal sacrifice is a feature of atonement) on the Day of Judgment. As was the case with ritualistic animal sacrifices, four days of segregation was required in order to heed the object from becoming imperfect. Man, on his day of judgment is hence, also asked to prepare himself at least four days in advance. If there are less than four days between the Sabbath preceding the New Year and the New Year itself, the Selichos services (as is the case this year) start on the preceding Sabbath. QUESTION: Why must the High Holiday selichoth services begin at midnight Saturday night? ANSWER: It was desired to start the week off with sentiments of penitence, and so with the dismissal of the Sabbath, penitence is immediately begun. The midnight hour has long been known as one of silence and awe, thereby promoting introspective thoughts. It is for this same reason that the Selichos on the following days are said before the break of dawn when we are likely to submerge our minds into serious thinking.

PAGE TWELVE Jew 1stflcridliair Face Facts George J. Talianoff Executive Director A.D.L. The Assistant Secretary of War has announced that 83 Miami Beach hotels, which had been in service more than three years, are to receive their honorable discharge around November 15. Miami Beach can truly be proud of the role played by the hotels, which represent the community's largest industry, in the successful completion of the war. The hotels provided the facilities which, at the outbreak of the war, enabled 25 per cent of the officers and 20 per cent of the ground crew of our tremendous air force to be trained in this community. During this past year the hotel facilities made possible the largest of five redistribution stations in the country. It is increasingly evident that Miami Beach, a relatively small community, has contributed much to the success of our military might. High praise is due many organizations and many individuals for their unstinting efforts in behalf of the thousands of service personnel who have passed through this area. Their selfless efforts would fill a large volume, and space in this column docs not permit the enumeration of all their contributions. Today, however, we wish to pay tribute to those who have made possible the Miami Beach Snack Bar which, in the four ^j710 S. W. 12th AV.

L. PLUMMER FUNERAL DIRECTOR months of its operation, has done much to engender good-will and improved relations between the military and civilians. The Snack Bar became a reality on May 2, 1945. It was a long felt need as far back as June, 1944 when we surveyed the area and noted the absence of an effective medium whereby the Jewish community could conduct war service work directly with servicemen of all faiths, thus giving our veterans a true impression of representative patriotic Jews. From its very first day, the operation of the Snack Bar was an assured success. Its popularity spread rapidly among servicemen stationed in and about this area. Staffed by 400 Jewish hosts and hostesses, the Snack Bar has served approximately 7,000 servicemen and their families and friends weekly. The semi-annual report of the Florida Regional Office of the Anti-Defamation League dated Julv 1, 1945 pays high tnli ite to those who have made possible this splendid public relations project. The report reads in part: "To the men and women volunteers at the Snack Bar who have given unstintingly of their efforts, as well as the Jew staff members, should go the credit for the success of this project." An example of the unselfish spirit motivating these volunteers is that shown by the chairman of the Snack Bar, Carl Weinkle. During the construction of the Snack Bar. he worked day and night in its organization and in preparation for its opening. Thereafter, in addition In his dunes as chairman, he has donned an apron to work a shift (and usually more) weekly. Without thought of reward or recognition, he, like so many volunteers, have worked arduously and selflessly. Our community is indeed proud of men like Carl Weinkle and the hundreds of hosts and hostesses he typifies, who have made possible the success of the Snack Bar.

The Rabbinical Association ot Greater Miami requests all merchants of our faith to close their stores during the High Holy Days. We know that the great majority of our people realize the solemnity of these days and will remain closed on September 8 and September 17. Yet. in the past, there have been some who have failed to close their businesses on Rosh Hashana and Yom Kippur. This, not only has reflected unfavorably upon us from a religious standpoint, but also has adversely affected our relationship with those not of our faith. Our observance of our religion has brought us admiration from all men in all times. Let us not lose our own dignity and the admiration of our community at this time. We pray for a truly happy New Year for all. .... Greater Miami Rabbinical Association Rabbi Jacob H. Kaplan.

He is hitting the long ball, too, strong proof that he has not lost his eye as so many claim. Hank thinks returning vets will benefit more by putting in a spring training season before tackling the game as he did without any warm-up. Incidentally Hank recently received a Ford auto franchise for New York City from none other than Henry Ford himself. Can it be the Detroit motor magnate's conscience is bothering him? The good burghers of Flatbush gave Goody Rosen a day last Sunday at Ebbets Field. Ever since Goody has been in a batting slump going from bad to worse. Against the western nines Roscy has been hitting a cool .239 to drop him from top to third place in the National League batting race, he is still boasting a .345 average. Goody received a wrist watch and two boxes of cigars. You never see the Toronto lad without a stogie in his mouth. He generally sits behind us at Madison Square Garden on fight nights and is never without a cigar in his mouth. The weed looks like a bat in his mouth, it's so big.

Windows Communication Foundation From the Inside
When using a typed contract, incoming messages on the server are shredded on your behalf to be turned into method calls and parameters. Ordinarily, the particular method call selected for an application messages will have the same parameterized contract as the message. This allows the transformation between messages and parameters to be made with a high degree of fidelity. However, operations also permit fault responses in addition to the normal application response.
The parameterized fault contract is going to look nothing like the standard application contract. Therefore, there's really no transformation that will take you from the fault message to the same parameterized contract in a way that makes any sense. The response that comes back from the server is unrepresentable using the standard data structure that the application is expecting to receive for an application response. This is why with a typed contract fault messages have to be expressed as an exceptional condition. Exceptions tend to transform the message with a much lower fidelity to the original content.
With an untyped contract, incoming messages on the server are not shredded on your behalf but rather preserved in their entirety. You can think about this as performing the transformation between messages and parameters with perfect fidelity since the parameter is equal to the message. Similarly, any message response, whether it's a fault response or a normal application response, is also going to be representable with perfect fidelity. Both types of responses have the same format with an untyped contract so the application can handle them equally well. This is why with an untyped contract fault messages are preserved as messages. One of the major reasons for using untyped contracts is to have great fidelity with the wire. It wouldn't make sense to force the application to lose that fidelity for a certain class of messages.
If you choose to in your application though, you can still run the same exception machinery. For details, read some of the past articles on creating and consuming faults.

Friedman (1956) and Muth (1960)¶
Milton Friedman [Fri56] (1956) posited that consumer’s forecast their future disposable income with the adaptive expectations scheme
$$ y_{t+i,t}^* = K \sum_{j=0}^\infty (1 - K)^j y_{t-j} \tag{1} $$
where $ K \in (0,1) $ and $ y_{t+i,t}^* $ is a forecast of future $ y $ over horizon $ i $.
Milton Friedman justified the exponential smoothing forecasting scheme (1) informally, noting that it seemed a plausible way to use past income to forecast future income.
In his first paper about rational expectations, John F. Muth [Mut60] reverse-engineered a univariate stochastic process $ \{y_t\}_{t=- \infty}^\infty $ for which Milton Friedman’s adaptive expectations scheme gives linear least forecasts of $ y_{t+j} $ for any horizon $ i $.
Muth sought a setting and a sense in which Friedman’s forecasting scheme is optimal.
That is, Muth asked for what optimal forecasting question is Milton Friedman’s adaptive expectation scheme the answer.
Muth (1960) used classical prediction methods based on lag-operators and $ z $-transforms to find the answer to his question.
Please see lectures Classical Control with Linear Algebra and Classical Filtering and Prediction with Linear Algebra for an introduction to the classical tools that Muth used.
Rather than using those classical tools, in this lecture we apply the Kalman filter to express the heart of Muth’s analysis concisely.
The lecture First Look at Kalman Filter describes the Kalman filter.
We’ll use limiting versions of the Kalman filter corresponding to what are called stationary values in that lecture.
A Process for Which Adaptive Expectations are Optimal¶
Suppose that an observable $ y_t $ is the sum of an unobserved random walk $ x_t $ and an IID shock $ \epsilon_{2,t} $:
$$ \begin{aligned} x_{t+1} & = x_t + \sigma_x \epsilon_{1,t+1} \cr y_t & = x_t + \sigma_y \epsilon_{2,t} \end{aligned} \tag{2} $$
where$$ \begin{bmatrix} \epsilon_{1,t+1} \cr \epsilon_{2,t} \end{bmatrix} \sim {\mathcal N} (0, I) $$
is an IID process.
Note: A property of the state-space representation (2) is that in general neither $ \epsilon_{1,t} $ nor $ \epsilon_{2,t} $ is in the space spanned by square-summable linear combinations of $ y_t, y_{t-1}, \ldots $.
In general $ \begin{bmatrix} \epsilon_{1,t} \cr \epsilon_{2t} \end{bmatrix} $ has more information about future $ y_{t+j} $’s than is contained in $ y_t, y_{t-1}, \ldots $.
We can use the asymptotic or stationary values of the Kalman gain and the one-step-ahead conditional state covariance matrix to compute a time-invariant innovations representation
$$ \begin{aligned} \hat x_{t+1} & = \hat x_t + K a_t \cr y_t & = \hat x_t + a_t \end{aligned} \tag{3} $$
where $ \hat x_t = E [x_t | y_{t-1}, y_{t-2}, \ldots ] $ and $ a_t = y_t - E[y_t |y_{t-1}, y_{t-2}, \ldots ] $.
Note: A key property about an innovations representation is that $ a_t $ is in the space spanned by square summable linear combinations of $ y_t, y_{t-1}, \ldots $.
For more ramifications of this property, see the lectures Shock Non-Invertibility and Recursive Models of Dynamic Linear Economies.
Later we’ll stack these state-space systems (2) and (3) to display some classic findings of Muth.
But first, let’s create an instance of the state-space system (2) then
apply the quantecon
Kalman class, then uses it to construct the associated “innovations representation”
# Make some parameter choices # sigx/sigy are state noise std err and measurement noise std err μ_0, σ_x, σ_y = 10, 1, 5 # Create a LinearStateSpace object A, C, G, H = 1, σ_x, 1, σ_y ss = LinearStateSpace(A, C, G, H, mu_0=μ_0) # Set prior and initialize the Kalman type x_hat_0, Σ_0 = 10, 1 kmuth = Kalman(ss, x_hat_0, Σ_0) # Computes stationary values which we need for the innovation # representation S1, K1 = kmuth.stationary_values() # Form innovation representation state-space Ak, Ck, Gk, Hk = A, K1, G, 1 ssk = LinearStateSpace(Ak, Ck, Gk, Hk, mu_0=x_hat_0)
Some Useful State-Space Math¶
Now we want to map the time-invariant innovations representation (3) and the original state-space system (2) into a convenient form for deducing the impulse responses from the original shocks to the $ x_t $ and $ \hat x_t $.
Putting both of these representations into a single state-space system is yet another application of the insight that “finding the state is an art”.
We’ll define a state vector and appropriate state-space matrices that allow us to represent both systems in one fell swoop.
Note that$$ a_t = x_t + \sigma_y \epsilon_{2,t} - \hat x_t $$
so that$$ \begin{aligned} \hat x_{t+1} & = \hat x_t + K (x_t + \sigma_y \epsilon_{2,t} - \hat x_t) \cr & = (1-K) \hat x_t + K x_t + K \sigma_y \epsilon_{2,t} \end{aligned} $$
The stacked system$$ \begin{bmatrix} x_{t+1} \cr \hat x_{t+1} \cr \epsilon_{2,t+1} \end{bmatrix} = \begin{bmatrix} 1 & 0 & 0 \cr K & (1-K) & K \sigma_y \cr 0 & 0 & 0 \end{bmatrix} \begin{bmatrix} x_{t} \cr \hat x_t \cr \epsilon_{2,t} \end{bmatrix}+ \begin{bmatrix} \sigma_x & 0 \cr 0 & 0 \cr 0 & 1 \end{bmatrix} \begin{bmatrix} \epsilon_{1,t+1} \cr \epsilon_{2,t+1} \end{bmatrix} $$$$ \begin{bmatrix} y_t \cr a_t \end{bmatrix} = \begin{bmatrix} 1 & 0 & \sigma_y \cr 1 & -1 & \sigma_y \end{bmatrix} \begin{bmatrix} x_{t} \cr \hat x_t \cr \epsilon_{2,t} \end{bmatrix} $$
is a state-space system that tells us how the shocks $ \begin{bmatrix} \epsilon_{1,t+1} \cr \epsilon_{2,t+1} \end{bmatrix} $ affect states $ \hat x_{t+1}, x_t $, the observable $ y_t $, and the innovation $ a_t $.
With this tool at our disposal, let’s form the composite system and simulate it
# Create grand state-space for y_t, a_t as observed vars -- Use # stacking trick above Af = np.array([[ 1, 0, 0], [K1, 1 - K1, K1 * σ_y], [ 0, 0, 0]]) Cf = np.array([[σ_x, 0], [ 0, K1 * σ_y], [ 0, 1]]) Gf = np.array([[1, 0, σ_y], [1, -1, σ_y]]) μ_true, μ_prior = 10, 10 μ_f = np.array([μ_true, μ_prior, 0]).reshape(3, 1) # Create the state-space ssf = LinearStateSpace(Af, Cf, Gf, mu_0=μ_f) # Draw observations of y from the state-space model N = 50 xf, yf = ssf.simulate(N) print(f"Kalman gain = {K1}") print(f"Conditional variance = {S1}")
Kalman gain = [[0.181]] Conditional variance = [[5.5249]]
Now that we have simulated our joint system, we have $ x_t $, $ \hat{x_t} $, and $ y_t $.
We can now investigate how these variables are related by plotting some key objects.
fig, ax = plt.subplots() ax.plot(xf[0, :], label="$x_t$") ax.plot(xf[1, :], label="Filtered $x_t$") ax.legend() ax.set_xlabel("Time") ax.set_title(r"$x$ vs $\hat{x}$") plt.show()
Note how $ x_t $ and $ \hat{x_t} $ differ.
For Friedman, $ \hat x_t $ and not $ x_t $ is the consumer’s idea about her/his permanent income.
fig, ax = plt.subplots() ax.plot(yf[0, :], label="y") ax.plot(xf[0, :], label="x") ax.legend() ax.set_title(r"$x$ and $y$") ax.set_xlabel("Time") plt.show()
We see above that $ y $ seems to look like white noise around the values of $ x $.
fig, ax = plt.subplots() ax.plot(yf[1, :], label="a") ax.legend() ax.set_title(r"Innovation $a_t$") ax.set_xlabel("Time") plt.show()
MA and AR Representations¶
Now we shall extract from the
Kalman instance
kmuth coefficients of
- a fundamental moving average representation that represents $ y_t $ as a one-sided moving sum of current and past $ a_t $s that are square summable linear combinations of $ y_t, y_{t-1}, \ldots $.
- a univariate autoregression representation that depicts the coefficients in a linear least square projection of $ y_t $ on the semi-infinite history $ y_{t-1}, y_{t-2}, \ldots $.
Then we’ll plot each of them
# Kalman Methods for MA and VAR coefs_ma = kmuth.stationary_coefficients(5, "ma") coefs_var = kmuth.stationary_coefficients(5, "var") # Coefficients come in a list of arrays, but we # want to plot them and so need to stack into an array coefs_ma_array = np.vstack(coefs_ma) coefs_var_array = np.vstack(coefs_var) fig, ax = plt.subplots(2) ax[0].plot(coefs_ma_array, label="MA") ax[0].legend() ax[1].plot(coefs_var_array, label="VAR") ax[1].legend() plt.show()
The moving average coefficients in the top panel show tell-tale signs of $ y_t $ being a process whose first difference is a first-order autoregression.
The autoregressive coefficients decline geometrically with decay rate $ (1-K) $.
These are exactly the target outcomes that Muth (1960) aimed to reverse engineer
print(f'decay parameter 1 - K1 = {1 - K1}')

This is kind of an extension from a previous post that I did. The following code I got from KevinWorkman and it deals with loading a wav file as a resource. I took Kevin's code and created a stand alone program to see if it works. I can get it to compile and run without errors but no sound plays. I'm using Eclipse IDE.
I've imported the wav file into the src directory which contains the class that calls the resource. I've also imported it into the root directory of the project itself. I've used a forward slash at the beginning of the file name. I also tried to just load it as a File instead of using getClass().getResource("boxing_bell.wav"); I can't get it to play.
I'm at a complete loss.
Here's the code:
Code Java:
public class playClip { private Clip music; private void startSong(){ try{ System.out.println("Starting...\n"); AudioInputStream stream = AudioSystem.getAudioInputStream( getClass().getResource("boxing_bell.wav")); // AudioInputStream stream = AudioSystem.getAudioInputStream(new File("boxing_bell.wav")); music = AudioSystem.getClip(); music.open(stream); music.start(); System.out.println("Done...\n"); } catch(Exception e){ e.printStackTrace(); music = null; } } public static void main(String args[]) { playClip play = new playClip(); play.startSong(); } }
I also tried making a resource directory within the src directory and including that in the build path.
Any ideas of what I'm doing wrong? I think it has more to do with Eclipse than the code. The reason I say this is I found a book on Safari Online that is almost identical to the code above.
Can you say "Clueless!"
Thanks

Facelets seems to really scratch an itch for the JSF development community. I've gotten a lot of positive feedback from my first article about Facelets, and I'm looking forward to showing you more fun stuff you can do with Facelets in this article. Kudos to Jacob Hookom and everyone else involved in the development of Facelets!
In my last article, I introduced the concept behind Facelets and showed you how to create and manipulate its HTML-style templates and reusable composition components. In this article, I build on that discussion, using many of the same examples and components I introduced then. For starters, I show you a pain-free way to do Internationalization using a Facelets expression language (EL) function. Next, I show you how to create reasonable defaults and custom logic tags. Finally, I show you how to do lightweight metaprogramming in Facelets.
Because so many of the examples in this article build on the ones from my previous article, I strongly suggest you read that article first. You might also want to download the example code for this article and install Facelets (and Tomahawk) before going further.
Internationalization made easy
Internationalization doesn't have to hurt when you're working with Facelets. For the first exercise, I show you how to extend the field composition component from the last article to work with dates, Booleans, and all manner of Java types that should be displayed as text. I also show you how to use reasonable defaults to internationalize the label for the field.
Recall from last time that the field composition component uses the field name as its default label if the label is not passed, as shown here:
Say you would like to change that. Instead of loading the
fieldName as its default label, you want the field
composition component to look up the
fieldName in the
resource bundle associated with Faces. For this, you create a tag
library that defines tags and EL functions. First,
you create an EL function that looks up a
fieldName in
the resource bundle. If it can't find the label in the resource bundle,
it tries to generate a
fieldName based on the camel case of the given
fieldName. Listing 1 shows an example usage:
Listing 1. Example usage of the EL function
In Listing 1, I the EL function
arc:getFieldLabel(fieldName,namespace) to look up
the
fieldName in the resource bundle
associated with Faces. The
getFieldLabel()
method actually looks up the label in the resource bundle. Here are the
steps to create an EL function:
- Create a
TagLibraryclass.
- Create a Java utility class.
- Register the
getFieldLabel()method.
- Register the
TagLibraryclass.
- Register the facelets-taglib descriptor file.
The following sections explain these steps one by one and show you how to use your new EL function.
Step 1. Create a TagLibrary class
EL functions and logic tags are defined in a Facelets
TagLibrary class. To create a
TagLibrary, class you need to subclass
AbstractTagLibrary, as shown in Listing 2:
Listing 2. Subclassing AbstractTagLibrary
Once the tag library is defined, you can add EL functions and logic tags to it.
Step 2. Create a Java utility class
Next you need to create a Java utility class that has a static method
called
getFieldLabel(). This utility method has
no special tie to Facelets; it's just a regular Java static method, as
shown in Listing 3:
Listing 3. The Java utility class with getFieldLabel()
The
getFieldLabel() method shown in Listing
3 looks up the field in the resource bundle associated with JSF. If it
cannot find the field, it splits and capitalizes the camel-case string,
such that a "firstName" field name becomes "First Name." This gives you
a reasonable default, which you can still set up in the resource bundle
if you want to override it.
Step 3. Register the getFieldLabel method
In the
AbstractTagLibrary class shown in Listing 2 (
JsfCoreLibrary), you need to register the
getFieldLabel() method with the base class so that it
is available as an EL function. I do this in Listing 4:
Listing 4. Registering JsfCoreLibrary.java as an EL function
As you can see, Listing 4 just iterates through all the methods
on the
JsfFunction class using reflection. It
then adds all
JsfFunction's static methods
using the inherited method
addFunction().
Step 4. Register the TagLibrary class
You've now defined the EL function and the
TagLibrary class that contains it. Next, you need
to register your new
TagLibrary class so that
it can be found by Facelets. You do this by declaring a new library
class in a new facelets-taglib file called jsf-core.taglib.xml, as shown
in Listing 5:
Listing 5. jsf-core.taglib.xml
Step 5. Register the facelets-taglib descriptor file
For Facelets to find your tag library, you need to register it in the WEB-INF/web.xml file, as shown in Listing 6:
Listing 6. Registering the new taglib with Facelets
Notice that I added jsf-core.taglib.xml to the semicolon-delimited list
passed to the
init-param facelets.LIBRARIES. Composition components
go in their own taglib file. EL functions and Facelets logic tags can
go in the same taglib file.
Using the EL function in a composition component
Now that you've defined the EL function, placed it in the Facelets taglib
descriptor file, and registered the taglib descriptor file in web.xml, you can
start to use the tag. In the field composition component, you can use the
arc:getFieldLabel to look up the label in the resource bundle, as shown in Listing 7:
Listing 7. Using the EL function
Notice I imported that "arc" library by specifying its namespace in
the
xmlns:arc="" HTML element. The
namespace has to match the namespace declared in the
TagLibrary class (
JsfCoreLibrary in this case) as shown here:
This might seem like a lot of work, even for just five steps. However, once you've done this basic setup, you can easily add more logic tags and EL functions without going through the same hassle every time. You'll have reasonable defaults for all your field label names. And, if your application only supports your native tongue and location, then for most cases, you won't have to add entries in the resource bundle. You'll only have to add entries in the resource bundle if you want a special label or if you start to use your application for other languages and/or locations.
Facelets solves a pet peeve of mine about internationalization: writing a lot of special code for something I may never need. Now it's free! Next, let's see what happens if you decide you want to change the field tag so that it generates Booleans, dates, and text components automatically.
Creating custom logic tags
First, you want to add some metaprogramming capabilities to the
field.jsp tag. For this, you create Facelets
logic tags that tell you if a particular value binding type is a
Boolean (
isBoolean), some form of text (
isText), or a date (
isDate). Then you use the tags to render the
appropriate component.
Listing 8 shows the usage for these tags (field.xhtml):
Listing 8. field.xhtml
The field.xhtml code in Listing 8 renders an
inputText if the value binding is some sort of
text. It renders a
selectBooleanCheckbox if
the value binding type is a Boolean. Finally, it renders a Tomahawk
calendar component if it is a date (see "About
Tomahawk").
Next, you create a value binding to get the type that is being bound to a particular component. The value binding has information
about the type of value the component is bound to. If you've used JSF,
then you're already familiar with value bindings; for example,
#{Employee.firstName} is a value binding tag that
likely equates to a string type while the
#{Employee.age} tag likely equates to an integer
type. In the next section, you learn how to create a value binding tag
using Facelets.
Create a value binding tag
There are four steps to creating a tag that retrieves a value binding in Facelets:
- Create a class that subclasses the
TagHandler.
- Register the attributes in the constructor.
- Override the apply method.
- Register the tag in the
JsfCoreLibraryclass.
The following sections explain each of the steps to build a value-binding tag and then show you how to use it.
Step 1. Create a class that subclasses TagHandler
You can use a Facelets
TagHandler to
inject the logic to decide whether components in the body of a tag are
added to the component tree. Remember that the endgame of a Facelets
template is to create a JSF component tree.
Listing 9 shows how the
SetValueBindingHandler tag subclasses
TagHandler. The
SetValueBindingHandler just defines a variable and
puts the variable in the Facelets scope so your logic tags can reuse the
variable.
Listing 9. SetValueBindingHandler subclasses TagHandler
Step 2. Register the attributes in the constructor
When you write Facelets tags, it is important to realize that the
attributes are defined by the tag itself and not in an XML file.
The constructor of
SetValueBindingHandler defines and registers two attributes (var and valueBinding) in the constructor, as shown in Listing 10:
Listing 10. Register the attributes in the constructor
Step 3. Override the apply method
Next, you override the apply method in
SetValueBindingHandler. Typically, you override the
apply method to programmatically decide if the components defined in the
body of the tag are added to the component tree. However,
SetValueBindingHandler just defines a variable
(whatever var is set to; for example, "vb") to the value binding that
was passed. Listing 11 shows the code to override the apply method:
Listing 11. Override the apply method
Listing 11 defines two variables: var and var + "Type". Next, you simply put the variables into the faceletsContext (see my comments in Listing 11 for more details).
Step 4. Register the tag in the JsfCoreLibrary class
You can use the same
JsfCoreLibrary for
this example as for the previous one. A
TagLibrary can contain both EL functions and logic
tags. So, for the final step of this exercise, you register the
SetValueBindingHandler tag in the
JsfCoreLibrary by calling the superclass
addTagHandler, as shown in Listing 12:
Listing 12. Register the tag in the JsfCoreLibrary
The nice thing about Facelets is that if you compare developing tags in
Facelets to writing equivalent tags in JSP, it takes a lot less XML. You can
easily develop many more tags and register them in the
JsfCoreLibray.
Notice that the name of the tag is
setValueBinding.
Using the custom logic tag
Now that you've defined the tag,
setValueBinding, you can start using it, as shown
in Listing 13:
Listing 13. Using the setValueBinding tag
You don't have to import anything or set up anything in web.xml. Once you define a tag library (like "arc"), you can add tags and functions to it without updating any XML files. Yes, you can escape XMHell!
Metaprogramming with Facelets
For a last little bit of Facelets fun (for this article), you'll create a tag that allows you to add components defined in the body if the value binding is of a certain type.
The magical tag,
IsTypeHandler(),
selectively decides if a component gets added to the component tree. The
tags calls
this.nextHandler.apply(faceletsContext,
aParent) if the components defined in the body should be added to
the component tree. The
isTypeHandler() calls
the abstract method
isType() to determine if it
should call
this.nextHandler.apply(faceletsContext,
aParent) and add the components defined in the body of tag
handler to the component tree. Listing 14 shows the base class for all of this:
Listing 14. Base class for handling types
Next, you add a tag per type that you want to handle, as I do in Listing 15:
Listing 15. Handling specific types
Listing 15 just uses the type of the value binding to decide if
the components defined in the tag's bodies get added to the component tree.
Each tag overrides the
isType() method.
Currently, I'm using just the type to determine if the body components
get added to the tree, but you could easily use annotations or other
forms of metadata if you wanted.
Naturally, your task isn't complete until you register all of
the above tags with the
JsfCoreLibrary, as shown in Listing 16:
Listing 16. Adding the type handling tags to the TagLibrary
Now you have three more tags in your taglibrary:
isBoolean,
isText, and
isDate().
You can use these tags in your field tag as shown in Listing 17:
Listing 17. Final field.xhtml
Your field tag now displays an
inputText
field if the value binding is of type
Integer,
String,
BigDecimal,
Character,
Long,
Short,
Byte,
Float,
Double,
short,
int,
char, etc. The
field tag displays a check box if the value binding type is a boolean or
a Boolean. And it displays a Tomahawk calendar component if the value
binding is of type
java.util.Date -- which, frankly, is very cool.
In this article, I've shown you some fun and fairly powerful applications of Facelets. The Facelets EL function takes a lot of the pain out of internationalization, and custom logic tags allow you to extend Facelets' built-in logic tags. Along the way, you've seen how easy it was to extend the simple examples from my previous article with more advanced functionality. I showed you how to update the field composition component to work with dates (Tomahawk calendar), Booleans (check boxes), and all manner of Java types that should be displayed as text. I also introduced you to reasonable defaults, which I used to internationalize the label for the field component. Keep an eye out for more fun with Facelets in the coming months!

I spent a lot of time in searching if this was actually possible, did a lot of research, tried many different methods and finally I’ve been successful.
Before I start let me give you some background;
Business Scenario
The Sender system is IBM WebSphere MQ and the receiver side is an SFTP.
So it becomes JMS to SFTP.
Business Requirement
The sender side is splitting each xml document to 3 mb parts. But it is splitted irregularly.
For example;
This is the structure before they split and what receiver system expects from PI.
The xml document above becomes like below parts when client put the files to MQ.
Another requirement is, the message parts are uploaded to MQ unordered. So last message part can be at first row or first message part can be at middle rows etc.
And total size of the complete/unsplitted xml document can be max. 50+ MB.
Also quantity of message parts is unknown and most important thing is there is nothing to use to define the message parts sequence.
Solution Tries
Firstly it occurred to me that I can send message parts to ccBPM and merge them with a transformation step. Then I tried this scenario.
Because we don’t have any possible field to use in correlation, I made dummy correlation like giving ‘sender component’.
When I run this scenario, I noticed that incoming messages are failing on transformation step. I thought that reason of this exception is while messages goes in to mapping, they are tried to parse as if the message is xml.
By the way sender and receiver adapter validations are off.
To achieve it I tried to add xml elements like <Envelope> and </Envelope> at beginning of the message and end of the message to convert my irregular xml message to smooth and parsable xml message.
First I tried this method using XSLT by embedding incoming message to smooth xml structure as CDATA. This was 1. step on Operation Mapping and the 2. step was my actual mapping which I merge incoming messages as below.
This attempt failed. Because XSLT expects incoming data as xml format.
Then I used Java Mapping instead of XSLT with the same logic; embedding incoming data in to xml structure as CDATA. But this time I placed java mapping in front of the ccBPM instead of transformation step like below. This attempt failed too.
I realized that it mighty have impossible to handle irregular xml after message go out from sender channel.
Then I decided to write a simple custom module on JMS adapter to convert incoming data to xml message by adding xml tags beginning and end of the message.
After the start of writing EJB, an idea came; why I didn’t just make a runnable jar and call it from channel?
Solution
I made some changes on configuration and made it JMS to File as shown below.
PI is taking message parts from MQ and putting them in a folder on itself without any conversion.
While leaving the messages to folder, there is an operating system command on receiver file adapter which works after message processing.
With this command PI executes a script file whenever each message file created in target folder.
The script file executes a runnable jar file. But before the execution it checks whether the jar is running currently or ready to run at that moment. This check is necessary to prevent triggering jar file on every message part. It must run once when the first message part placed in the folder.
When the jar app is executed, it fetches all message part files from PI’s output folder and goes in a loop which turns number of file times.
First looks for the begin of root element if the message part contains it then it is assigned to a string. Then looks for the end of root element likewise and it is assigned to another string. Remainders is assign to another else string by concatenating each other in order and in a row.
After each assignment, currently processing file is moved to ‘processed’ folder.
At the end of the loop, which means all message part files are processed and moved from PI’s output folder, the strings assigned above are concatenated and this generates complete xml. At the same time this strings represents three main part of the complete xml which are begin part, middle parts and end part.
Then the new complete xml file is created with containing timestamp in filename to prevent duplicate situation.
The checking logic in bat file is, if jar file name is ‘ready’ then change its name to ‘running’ and execute it. Then check the folder continuously which PI puts incoming message parts, until there is no file anymore. This means jar app fetched all message parts and done its job. Then bat file changes the jar file’s name again to ‘ready’ then the script ends.
Also I made some performance tests like merging 20 files which equals to 60 mb total. During the tests I have observed that playing with big data causes Java heap size error. To achieve it I added -Xmx parameter to bat file which sets maximum java heap size.
As a result the script in front of the jar app enables to run jar app once until all message parts processed.
Script file;

react-native-svg-transformer
React Native SVG transformer allows you import SVG files in your React Native project the same way that you would in a Web application when a using library like SVGR to transform your imported SVG images into React components.
This makes it easy to use the same code for React Native and Web.
Usage
Import your
.svg file inside a React component:
import Logo from "./logo.svg";
You can then use your image as a component:
<Logo width={120} height={40} />
If you use React Native version 0.56 or older, you need to rename your
.svg files to
.svgx.
Demo (iOS/Android/Web)
Installation and configuration
Step 1: Install react-native-svg library
Make sure that you have installed and linked
react-native-svg library:
Step 2: Install react-native-svg-transformer library
yarn add --dev react-native-svg-transformer
Step 3: Configure the react native packager
For React Native v0.57 or newer / Expo SDK v31.0.0 or newer
Merge the contents from your project's
metro.config.js file with this config (create the file if it does not exist already).
metro.config.js:"] } }; })();
If you are using Expo, you also need to add this to
app.json:
{ "expo": { "packagerOpts": { "config": "metro.config.js" } } }
For React Native v0.56 or older
React Native versions older than 0.57 do not support running the transformer for
.svg file extension. That is why a
.svgx file extension should be used instead for your SVG files. This is fixed in React Native 0.57 and newer versions.
Add this to your
rn-cli.config.js (create the file if it does not exist already):
module.exports = { getTransformModulePath() { return require.resolve("react-native-svg-transformer"); }, getSourceExts() { return ["js", "jsx", "svgx"]; } };
For Expo SDK v30.0.0 or older
If you are using Expo, instead of adding the
rn-cli.config.js file, you need to add this to
app.json:
{ "expo": { "packagerOpts": { "sourceExts": ["js", "jsx", "svgx"], "transformer": "node_modules/react-native-svg-transformer/index.js" } } } | https://reactnativeexample.com/import-svg-files-in-your-react-native-project-the-same-way/ | CC-MAIN-2021-17 | refinedweb | 338 | 61.22 |

Great article, Jason.
Actually, there was a small mistake in those line below:
positive_lines = process_docs(‘txt_sentoken/neg’, vocab)
negative_lines = process_docs(‘txt_sentoken/pos’, vocab)
Thanks Arthur, fixed!

Thanks for the suggestion Vijay.
Excellent work! Very clear presentation.
Best regards
Thanks Jacek.
Hi Jason,
I created the model as instructed. But when I try to predict for a new text then I get an error saying the input shape is different.
When we fit a model, the input shape is fetched based on the training data. However, tokenizer.text_to_matrix gives a different shape for new text. Thereby, model cannot be used to predict new text.
Could you please suggest the solution for the same.
Thanks,
Sappy
You must prepare new text in exactly the same way as training data text.
I recommend using the same functions and even encoders used to prepare training data.
Dr. Jason,
I have used the model and saved to the disk as .h5 file. Then I loaded it with the function load_model(). Now I tried prediction using the above code and getting this error: ‘Tokenizer’ object has no attribute ‘word_index’. The same functions have been used throughout. What is wrong I couldn’t find out. Please suggest for corrections.
I’m sorry to hear that, I have not seen this error before.
I have some suggestions here:
Thank you Dr. Jason! Such a very valuable tutorial!
While playing with the models I’ve noticed, that splitting data (at least in this case) at different points results to VERY different accuracy (up to 5% difference). Say, we get test data from the beginning/middle or from the last reviews – all would yield different results. So, furthermore, I’ve experimented with sklearn train_test_split with different random_state numbers to split the dataset at different points – and the results depend so much on. (That is because tokenizer fits on varying set of tokens each time.)
What would be the best approach to tackle such situation and get the best out of it?
Excellent and an important observation Vladimir.
See this post for a more robust model evaluation strategy:
Nice, I like that simple approach. Thanks for sharing.
No problem.
Jason,
Please have a look at a more gracious approach to preprocess text, encode it as a term-matrix and convert to an array. I’ve created a tutorial in my blog, inspired by your awesome articles:
So, the idea is to use sklearn CountVectorizer! It accepts arguments and make all the necessary preprocessing: tokenize, define word size, filter stopwords, includes words with certain frequency occurence, and even more allows to make ngrams!
Grateful to you,
Cheers! –Vladimir
Nice one!
Also, sometimes it is good to split out all the pieces for learning (e.g. for beginners) or for more control/fine tuning.
Really helpful!!!!!!!
Thanks, I’m glad to hear that.
Hi Jason,
I created the model as instructed. But when I try to predict for a new text then when I always get result as 0. Please help.
Perhaps your model requires more tuning?
when I run the prediction function it gives me this …!!!

Looks like you have not copied all of the code from the example.
Can you please write us a full code ? i dont get how to include the last part the function part to get result of one tense !
Great content.
Thanks.
many thanks !
I’m glad it helped.
Do you think that stemming might improve the classification accuracy or do you think it might lead to overfitting?
It will likely simplify the problem and in turn lift skill.
Can you please clarify the predict function more please, and do i need to run the train snippet each time i want to test that on a new data ? thank u
I explain more how to make predictions with Keras models here:
Hi DR Jason,
It is a very good post, thank you it cleared me many points.
I have a question. I would like to know if instead of train test split it can be used k-fold cross validation? Or in the case of document classification it is not necessary k-fold cross validation?
Best regards.
It is a good idea if you have the resources, we often do not when it comes to NLP models.
Thank you.
Best Regards.
Hi Jason,
You’re blog, like this one helps me a lot for my work.
I would like to see how ‘Embedding’ would perform as compared to Bag-of-Words.
Do you have a tutorial using embedding for sentiment analysis?
Kind Regards,
Emmanuel
Thanks Emmanuel!
Yes, I have many such tutorials, type embedding into the blog search.
Thank you. My goal is to improve the performance of my existing ‘classical’ bag-of-words method using Multinominal Bayesian, for both sentiment analysis and document classification. It works well with document classification.
However, I am looking for a model with a better performance, especially for my sentiment analysis, given that comments are multiple languages.
Would you consider/think that using a multi-channel, N-gram in a CNN would improve the performance, in general?
Many thanks for the response :).
I wouldn’t guess, I would design experiments to discover.
It actually improved the accuracy!
Thank you so much for the great tutorial! Your tutorials has greatly improved my skills and understanding in ML.
Cheers,
Emmanuel
Thanks, nice work!
Jason, I’m newer to Python … would love to set up what you provided guidance on above … I’ve downloaded the movie preview data set … how do I run the first set of code though? “An example of cleaning the first positive review is listed below.” … when I put this code into IDLE on Python it returns a syntax error. My apologies for such a newbie question … I imagine once I get how to apply your code I can get the rest working.
Thanks for such a wonderful write up! Hope I can get it running soon.
I recommend running code from the command line, I have an example here:
I am using the same but using CNN i Got accuracy = 0.8 but when i make prediction function i Got all the result positive , have you an idea please?
Perhaps try re-running the example a few times and compare results?
Hi
Do you maybe know why the rank of yhat (as the returned value of Model.predict call above) is 2 and not one? Given your example above, my expectation would be that yhat is [1] and not [[1]].
Thanks
One prediction is made for each input sample.
Hello Jason, thank you for this post, it was really helpful 🙂
I have few questions and I was wondering if you could help me. Can we use the bag of words model with CNN or RNN ? And how about using a validation set, would it increase the accuracy ? Also you tlaked about running the program on GPUs, what’s the major changes that we have to make ?
Thnx
No, bag of words discards the temporal ordering required by CNN and LSTM.
Validation dataset does not impact model performance, it is used to evaluate model performance.
You must configure the underlying backend (tensorflow) to use CPU or GPU. I don’t provide instructions for this.
Thank you Jason, this was helpful
I’m happy to hear that.
NameError: name ‘model’ is not defined
Jason mentioned to save the model and the tokenizer file as below –
“Ideally, we would fit the model on all available data (train and test) to create a final model and save the model and tokenizer to file so that they can be loaded and used in new software.”
After fitting the model please save the model –
model.save(‘my_model.h5’)
After getting the tokenizer file , please save the tokenizer file –
from pickle import dump
dump(tokenizer, open(‘tokenizer.pkl’, ‘wb’))
Looks like you might have missed some lines of code.
Hi Vinay,
Can you tell me where exactly do we need to specify the line of code
“from pickle import dump
dump(tokenizer, open(‘tokenizer.pkl’, ‘wb’))”
and this one:
“model.save(‘my_model.h5’)”
In the first case we are saving the tokenizer to file, in the second we are saving the model to file.
Hello,
I want to read the raw data represented as sequences of integers ( System calls, ADFA-LD Dataset ) , how to do this, I cannot use the modes mentionned above ?
Thanks
You must encode each word in your vocab with a unique number.
But my vocab is a set of integers (between 1 and 340) each integer represent a unique system call.
Great! Perhaps start by prototyping a few models?
The problem is how to define Xtrain and Ytrain, cause I have only text and not an array. I tried the encoding with unique numbers but the same problem : I got errors in shape of Ytrain or others.
The question is: to train a model, Are we obliged to have dataset with columns and rows? is there a method to use the sequences directly, without transform them?
Thank you, and sorry for disturbing you
In general, the model will take multiple samples as input, where each sample is a vector for encoded words – encoded text.
Perhaps try running the above example and see how the text was encoded and passed as input to the model?
I tried this, I got this error:
valueError: specify a dimension (num_words argument), or fit on some text data first
I’m sorry to hear that, I have some suggestions here:
Hi Kahina,
I too got the same error. Later I realized that my ‘vocab.txt’ was empty.
Great tip.
Hi Jason,

I have not changed even one word of the code. Its exactly the same. Can you tell me what exactly might be the problem? Thanks!
Sorry to hear that, I have some suggestions here that might help:
Sorry, I did not mean error. I meant output
Hey, Jason, I feel the method here is quite similar to word embedding encoding method. I wonder which part is using bag-of-words? Is the following section ? Why do we use sequence encoding at the beginning ? Thank you.
modes = ['binary', 'count', 'tfidf', 'fre()
Bag of words is the mapping of words to a count vector.
The vector is not ordered, they are not sequences.
hi sir this one was a very good model!!
i have a query in my code .
i have made a model in NLP but i dont know hor can i predict my result can you help me with the code???
You can call model.predict()
Perhaps this will help:
Hi can you help on this error? this code is from deep learning for nlp

I don’t know about that function sorry.
Hi Dr. Jason,
Thank you for sharing this, it’s very helpful! I was wondering how exactly the program knows which reviews are positive and which negative? I understand that this line labels the reviews by 0 and 1:
“ytrain = array([0 for _ in range(900)] + [1 for _ in range(900)])”, but how does the program know which reviews in the range are negative and which positive? And why are both ranges 900?
Thanks!
Quinn
You’re welcome.
It learns from examples.
In that code we are preparing the class labels for the examples so that the model can learn. The numbers refer to the number of examples in each class.
Ah I see. Could you please confirm if my following understanding is correct?
We defined the training corpus variable as “docs = negative_lines + positive_lines”. Because of that, the negative reviews are in the first half of the array, while the positive ones are in the second half. And because we know that each section has 900 reviews each, we can simply label the first 900 with 0 to represent negative, and the other 900 with with 1 because it’s positive. If we had defined “docs” the other way around, i.e. “docs = positive_lines + negative_lines”, then when we label the reviews, we should be using “ytrain = array([1 for _ in range(900)] + [0 for _ in range(900)])”.
Is the above statement correct? Again, thank you very much.
Correct.
Thank you. Another question I was wondering about is that I see we only use either positive or negative reviews. Is it not recommended in general to include neutral reviews in the training dataset?
The reason that I’m asking is that I have a list of sentences that I’m currently classifying into positive/negative, and there are some sentences that are neutral. I’m inclined to include these as neutral instead of excluding them entirely.
That is a good idea and a natural extension to the tutorial.
Thank you. In that case, is there a way you would recommend labeling the positive/negative/neutral comments? Is 1 for positive, 0 for neutral and -1 for negative sensible? Or is it better to keep everything positive, i.e. using 0, 1 and 2? I tried to look this up online, but have found limited information on this. Thanks again!
It does not really matter.
Hi Sir,
When iam trying to create the model accuracy is coming as 65.5. What and all way we can improve the model performance, accuracy etc
Here are some suggestions:
Hi Jason!
Thanks for this fantastic post! I have an imbalance dataset of texts consisting of 4 languages with two labels and want to perform binary classification on it with CNN.
Any guide through the process? How is it different from a single-language dataset?
Thanks again!
Interesting, I recommend that you get creative and try a suite of different approaches.
I would recommend prototyping diffrent approaches, e.g. different inputs models for each language, maybe share an output model.
Hello thank you for your amazing tutorial.
I am new to nlp and I am confused about two things.
1 ) why did we make a list of vocabulary from the reviews and then again tokenized the reviews in the next step?
2 ) what is the role of the word scores? do they indicate that the word is pos or neg or is it only showing how much they have appeared in the reviews dataset?
thanks again!
Good questions.
We want control over the vocab used in the models, e.g. limit the words to those most useful/relevant makes the models simple/fast/effective.
We are predicting the sentiment in this tutorial, you can predict anything you like as long as you have training data.
thank you for your reply!
You’re welcome.
Hi Jason:
Wonderful text classification tutorial !.
I implemented additional options to the code, taken from yours other NLP tutorials, in order to evaluate several sensitivity analysis, such as:
– evaluate statistic variation for different training-validations dataset grouping, using k-fold cross-validations Sklearn API.
– evaluate results improvement by adding Deep Learning layers (or not), such as Embedding and 1D Convolutionals, to capture better words pattern extraction, before injecting them to dense layers of the fully connected part of the model. In the case of using embedding layer I also add the option to use GloVe pre-trained words vector weights (or not)
– Different options for “coding” document text words…into numbers. with keras functions such as: “texts_to_sequences()”, or “one_hot()2, or “texts_to__matrix()”.
– Different options to set up the number of “words features”, such as the maximum length of words contained in any document (1,301), or the number of different vocabulary words in all docs (24,875), or even any arbitrary number of features greater than the maximum length (e.eg. 100,000!).
by the way I experiment on using kernel_regulrarizer argument for dense layer, e.g. “l1-l2”, but I got a surprised result, the model does not learn at all (50% accuracy).!
I also apply train-validation split at the end (not at the beginning at you do). That is, after performing all the words preparation, cleaning, getting vocabulary and coding words/features for the whole dataset.
the best results I achieve it is around 89% accuracy
I am curious by the effect of adding embedding layers to the model, that change the 2D Input text documents defined by e.g. [number of docs, number of words features] to a 3D [number of docs, number of words features, number of word vector coordinates]… is this embedding layer applicable to other areas of ML/DL outside NLP (such as computer vision, time series, or is just specific to NLP?
in my case the most confused part of the sentiment analysis is the tedious procedure to convert text docs into texts, lines, words, cleaning, get docs vocabulary…and finally applying coding to convert words into numbers! I expect new APIs could overcome this long procedure with more powerful and simple APIs!
thanks
Very cool, thanks for sharing.
Yes, embeddings can be used with any categorical or ordinal inputs, for example:
Agreed, cleaning text is zero fun.
Thank you Jason!
I would take a look at the suggested tutorial for encoding categorical variables for deep learning
have a nice day!
Same to you!
Dear Jason,
I have gone through the tutorial and had an error:
==> AttributeError: module ‘tensorflow.python.framework.ops’ has no attribute ‘_TensorLike’
when it executed the the function “evaluate_mode()” near the end of the program:
results[mode] = evaluate_mode(Xtrain, ytrain, Xtest, ytest)
I have fixed so many errors so far and worked fine, but this one is hard. I have tried a few times, but I could not fix it. Hence, I need your help when you have a chance if possible. Many thanks for your help in advance.
I’m sorry to hear that you’re having trouble Rob, this may help:
i want to apply BOW model for an excel sheet (xlsx), comprising of question and answer columns, i please need your help. Thank you in advance !
Start by saving your spreadsheets as CSV files so you can load them in Python.
Is there any email or any other platform i can reach you at i’d like to share a few things with you and need your help please. Thank you !
Yes, the contact page linked in the menu:
Hi Jason,
Is there a way to analyze bigrams using the above methodology. I think the tokenizer library in keras doesn’t support it. Is there a way to create a fixed length vector of bag of words model with restricted vocabulary exactly like in this tutorial but with bigrams?
A bag of words has a fixed vocab, but is not concerned with document length.
You can use bag of bi-grams instead of words, but it would be a MASSIVE vector. A real pain.
Thank you Jason!
I have a labeled dataset to detect emotion, and I have a Spanish emotion lexicon.
I compute the TF scheme in order to obtain how frequently an expression (term, word) occurs in a document. and I want to incorporate the effective lexical features by check the presence of lexicon terms in the sentence and obtain a vector that represents each emotional category (anger, fear, sadness and joy). Finally, to carry out the classification, the concatenation of the TF sentence representation and the word-based features are used as input to the different machine learning algorithms.
how can I incorporate the effective lexicon features to obtain a vector? and how can I concatenate TF with Lexicon and used it as input to the different ML?
Perhaps ensemble the two different models?
Perhaps use a multi-input neural net model with separate input submodels for each feature type?
Perhaps contrast the two above approaches with one large concat vector input? | https://machinelearningmastery.com/deep-learning-bag-of-words-model-sentiment-analysis/ | CC-MAIN-2021-31 | refinedweb | 4,557 | 65.32 |
This is an interesting topic for discussion I think.
And then:
Good habits to have when doing python:
For example:
I know the above is Important because when you call a function from the outside it wont run your program like it is a stand alone script.(If I am saying it right).
Code: Select all
def main(): return if __name__ == "__main__": main()
List of Habits:
- New file for each class. (Like you must do in Java). is it good or bad and why
Commenting, how important is it really?
List of Features:
- Learning gtk and other gui scripting? how essential?
Slicing (ex. strvar[2:3]), do you realy use it?

FFI cook book
From HaskellWiki
This attempts to be a guide/tutorial/cookbook approach to writing a library using external (FFI) functions. Some people complain that cookbook approaches encourage EmptyDataDecls): >
There is also a third style, which uses newtype:
newtype EnvHandle = EnvHandle (Ptr EnvHandle)
You can also use something like Ptr a when functions expect void*, and use that to enforce type consistency. For instance, you have a function that expects a pointer to a buffer and returns the old one:
foreign import ccall "name_of_function" function :: Ptr a -> IO (Ptr a)
1.4 Working with structs
Please check me
For example suppose you had a struct like:
typedef struct { int a; char b; double c; } my_struct;
And you wanted to write a storable instance. Here pre-processing with hsc2hs tool can be helpfull. You would write it like this:
instance Storable Struct where alignment _ = #{alignment my_struct} sizeOf _ = #{size my_struct} peek ptr = do a <- #{peek my_struct, a} ptr b <- #{peek my_struct, b} ptr c <- #{peek my_struct, c} ptr return (MyStruct a, b, c) poke ptr (MyStruct a b c) = do #{poke my_struct, a} ptr a #{poke my_struct, b} ptr b #{poke my_struct, c} ptr c
Note that the #{alignment foo} syntax is not currently built-in to hsc2hs. You have to add the following line to your haskell source file to add the alignment syntax:
#let alignment t = "%lu", (unsigned long)offsetof(struct {char x__; t (y__); }, y__)
With a string field .
2 Calling C functions in DLL
by Ronald Guida, hCafe, 12 sep 2007
1. I can leave "test_foo.lhs" and "foo.cpp" as-is:
foo.cpp:
#include "foo.h" __stdcall int foo(int x) { return 3 * x + 1; }
test_foo.lhs:
> {-# OPTIONS_GHC -fglasgow-exts #-} > module Main > where > import Foreign > import Foreign.C > foreign import stdcall unsafe "foo" > c_Foo :: Word32 -> IO Word32 > main = do > putStrLn "Entering main" > let x = 7::Word32 > y <- c_Foo(x) > putStrLn $ "y = " ++ show y > putStrLn "Exiting main"
2. I need to change "foo.h" to the following:
#if BUILD_DLL #define DECLSPEC __declspec(dllexport) #else #define DECLSPEC __declspec(dllimport) #endif extern "C" { DECLSPEC __stdcall int foo(int x); }
3. I need to create a "foo.def" file and list the functions to be exported in a DLL:
LIBRARY foo DESCRIPTION "Foo Library" EXPORTS foo
Note: The library name on the first line must match the dll name. "LIBRARY foo" corresponds to "foo.dll"
4. The build process is as follows.
(1) gcc -DBUILD_DLL -c foo.cpp
(2) gcc -shared -o foo.dll foo.o foo.def \ -Wl,--enable-stdcall-fixup,--out-implib,libfoo.a
5. At this point, I'll have "foo.dll" and "libfoo.a". I can load my
"foo" library, as a DLL, into GHCi with the command: $ ghci -lfoo In reality, I would use: $ ghci test_foo.lhs -lfoo
6. Once I'm satisfied and ready to compile:
ghc --make test_foo.lhs -L. -lfoo
Notes: (1) "-L." directs GHC to look in the current directory for libraries. GHCi seems to look there by default.
(2) The resulting "test_foo.exe" will dynamicly load "foo.dll".
7. If I want a staticly linked executable instead:
ar rcs libfoo_static.a foo.o ghc --make test_foo.lhs -L. -lfoo_static
8. Finally, I can put the build steps into a Makefile:
# Makefile for foo test_foo.exe : test_foo.lhs libfoo.a foo.dll ghc --make test_foo.lhs -L. -lfoo test_foo_static.exe : test_foo.lhs libfoo_static.a ghc --make test_foo.lhs -L. -lfoo_static -o test_foo_static.exe libfoo.a : foo.dll foo.dll : foo.o foo.def gcc -shared -o foo.dll foo.o foo.def \ -Wl,--enable-stdcall-fixup,--out-implib,libfoo.a libfoo_static.a : foo.o ar rcs libfoo_static.a foo.o foo.o : foo.cpp foo.h gcc -DBUILD_DLL -c foo.cpp .PHONY: clean clean: rm -f *.[oa] rm -f *.dll rm -f *.hi rm -f *.exe

PyX — Example: drawing/pathitem.py
Constructing paths from pathitems
from pyx import * c = canvas.canvas() rect1 = path.path(path.moveto(0, 0), path.lineto(1, 0), path.moveto(1, 0), path.lineto(1, 1), path.moveto(1, 1), path.lineto(0, 1), path.moveto(0, 1), path.lineto(0, 0)) rect2 = path.path(path.moveto(2, 0), path.lineto(3, 0), path.lineto(3, 1), path.lineto(2, 1), path.lineto(2, 0)) rect3 = path.path(path.moveto(4, 0), path.lineto(5, 0), path.lineto(5, 1), path.lineto(4, 1), path.closepath()) c.stroke(rect1, [style.linewidth.THICK]) c.stroke(rect2, [style.linewidth.THICK]) c.stroke(rect3, [style.linewidth.THICK]) c.writeEPSfile("pathitem") c.writePDFfile("pathitem") c.writeSVGfile("pathitem")
Description
In this example, some simple paths are constructed out of pathitems, which are the basic building blocks of paths. While we only use
moveto,
lineto and
closepath instances, we can already see some features of paths in PyX.
In the first path instance
rect1, we alternatingly use
moveto and
lineto pathitem instances. A
moveto instance sets an internal current point, while a
lineto instance additionally creates a straight line connecting the old and the new current point. Due to the intermediate
moveto instances, we generate a path which contains 4 separate subpaths. When stroking this path with a thick linewidth in order to show the details, the corners of the result exhibits that the individual lines are not connected.
In the second case
rect2, we skip the intermediate
moveto instances. The default join method between pathitems within a single subpath is to miter them. This results in a different rendering except for the start and end point of the path.
In order to get rid of the ragged effect at the corners, we close the path as shown by
rect3. Here, one can (and should) skip the last connecting line since a
closepath pathitem implicitly adds a straight connection line between the first and the last point of the subpath.
PyX resembles the full PostScript path model. The whole PostScript path construction functionality is available by means of pathitems and the resulting PostScript code will make use of the corresponding PostScript operators. For PDF output, where some of the PostScript features are not available (all forms of arcs are missing in PDF), proper replacement code is generated automatically.
You might ask why you should skip the last straight connection line of finite length when closing a path. This is not a question of reducing the file size but increasing the rendering stability of the drawing. The problem is that in case of rounding errors a very short connection line might mistakenly be inserted when rendering a
closepath. Depending on the linejoin setting, this can create a major visual defect. | http://pyx.sourceforge.net/examples/drawing/pathitem.html | CC-MAIN-2016-36 | refinedweb | 461 | 60.82 |
preface
As mentioned earlier, the disadvantage of the IO multiplexing API, select and poll is that the performance is not enough. The more client connections, the more obvious the performance degradation. The emergence of epoll solves this problem. Reference The Linux Programming Interface A statistical comparison is as follows:
fd quantity poll CPU time(second) select CPU time(second) epoll CPU time(second) --------------------------------------------------------------------- 10 0.61 0.73 0.41 100 2.9 3.0 0.42 1000 35 35 0.53 10000 990 930 0.66 ---------------------------------------------------------------------
It can be seen that after fd reaches 100, select/poll is very slow, and epoll performs very well even if it reaches 10000, because:
- Every time select/poll is called, the kernel must check all the descriptors passed in; For epoll, each time epoll is called_ CTL, the kernel will associate the relevant information with the underlying file description. When the IO event is ready, the kernel will add the information to the ready list of epoll. Then call epoll_. Wait, the kernel only needs to extract the information in the ready list and return it.
- Each time select/poll is called, all file descriptors to be monitored should be passed to the kernel. When the function returns, the kernel should return the descriptors and identify which ones are ready. After the results are obtained, all descriptors should be judged one by one to determine which events are available; Epoll is calling epoll_ The monitoring list is maintained during CTL, epoll_wait does not need to pass in any information, and the returned result only contains ready descriptors, so there is no need to judge all descriptors.
Conceptually, epoll is understood to register the IO event of fd monitored to epoll (calling epoll_ctl), and then to call epoll's API waiting event to arrive (calling epoll_wait), and the kernel may maintain a read and write buffer for each fd.
- If I monitor read events and there is data in the read buffer, epoll_wait will return, and I can call read to read the data.
- If I monitor write events and the write cache is not full, epoll_wait will also return. At this time, I can call write to write data.
- If fd some errors occur, epoll_wait will also return. At this time, I can know according to the returned flag bit.
- If I monitor read events and a client connects, epoll_wait will return, and I can call accept to accept the client.
Introduction to epoll API
- int epoll_create(int size);
Create an epoll instance and return the file descriptor (fd) representing the instance. The size is ignored since Linux 2.6.8, but must be greater than 0.5
- int epoll_ctl(int epfd, int op, int fd, struct epoll_event *event);
Epoll control interface. epfd is the file descriptor of epoll. fd is the file descriptor to be operated. op has the following types:
- EPOLL_CTL_ADD registers fd the event. The event type is specified in event.
- EPOLL_CTL_MOD modifies registered fd events.
- EPOLL_CTL_DEL delete fd event.
epoll_event has an events member, which specifies the event type to be registered. The more important are:
- EPOLLIN fd readable events
- EPOLLOUT fd writable event
- EPOLLERR fd has an error. This event is always monitored and does not need to be increased manually
- When EPOLLHUP fd is suspended, this event is always monitored and does not need to be manually increased. This usually occurs when the socket is abnormally closed. At this time, read returns 0, and then clean up the socket resources normally.
epoll_event also has an epoll_data_t member. Custom data is set externally to facilitate subsequent processing.
- int epoll_wait(int epfd, struct epoll_event * events, int maxevents, int timeout);
Wait for an event to occur. If no event occurs, the thread will be suspended. Maxevents specifies the maximum number of events. The length of the event array passed in outside events should be equal to maxevents. When an event occurs, epoll will fill in the event information here. timeout specifies the maximum waiting time. 0 means to return immediately and - 1 means to wait indefinitely.
epoll_wait returns the number of waiting events. When it returns, traverse events to process fd. When epoll is no longer in use, close should be called to close epollfd.
Horizontal trigger and edge trigger
epoll trigger events have two modes, the default is called horizontal trigger (LT), and the other is called edge trigger (ET):
- LT mode: epoll if the read buffer of fd is not empty or the write buffer is not full_ Wait will always trigger the event (that is, return).
- ET mode: when the monitored fd state changes (from never ready to ready), the event is triggered once. After that, the kernel will not notify unless a new event comes.
//Thank you
The description of the original ET mode is wrong. It has been corrected after carefully reading the man document.
LT is much simpler to process than et. the read event is triggered and only needs to be read once. If the data is not read, epoll the next time_ Wait will return, and writing is the same; The ET mode requires that when the event is triggered, it is always read and write until it is clearly known that the reading and writing has been completed (the error code of EAGIN or EWOULDBLOCK is returned).
The process of horizontally triggered server program is as follows:
- accept a new connection, add the fd of the new connection to the epoll event, and listen to the epolin event.
- When the EPOLLIN event arrives, the data in the fd is read.
- If you want to write an event to this fd, add the EPOLLOUT event to epoll.
- When the EPOLLOUT event arrives, write the data to fd. If the data is too large to be written out at one time, keep the EPOLLOUT event first and continue writing the next time the event arrives; If the write out is complete, delete the EPOLLOUT event from epoll.
A practical echo program:
This time, we will use epoll and non blocking socket to write a really practical echo server, call fcntl function and set o_ The Nonblock flag bit turns the file descriptor of the socket into a non blocking mode. Non blocking mode is more complex to handle than blocking mode:
- Read, write and accept functions will not block. They will either succeed or return - 1 failure. errno records the reason for the failure. There are several error codes to pay attention to:
- EAGAIN or EWOULDBLOCK occurs only when fd is non blocking, which means that there is no data to read, no space to write, or no client can accept. Come back next time. These two values may be the same or different. It is best to judge together.
- EINTR indicates that it is interrupted by a signal, which can be called again.
- Other errors indicate a real error.
- It's troublesome to write data to an fd. We can't guarantee that all data will be written at one time, so we need to save it in the buffer first, then add a write event to epoll, and then write data to fd when the event is triggered. When the data is written, remove the event from epoll. This program saves the written data in the linked list.
We leave listening fd in blocking mode because epoll_ When the wait returns, it can be determined that there must be a client connected, so accept can generally succeed without worrying about blocking. The client connection uses a non blocking mode to ensure that there is no blocking when reading and writing is not completed.
The following is the code of this program. Some comments have been added in key places. It is more useful to look at the code carefully than to look at the text description:)

QProgressBar high memory usage
I have a program with a progress bar. It is used to signify the amount of a song played. This progress bar is used again for each song. When the program has been sitting for a few songs the progress bar uses quite a lot of memory.
I've written a little test application in both Python (my program is in python (PyQT)) and in C++. In both casses a fairly wide (800-1000px) progress bar running to completion uses about 50MB ram. That seems a bit exessive to me.
I'm guessing QrogressBar caches something. Can anyone help me find what can be done about the high memory usage?
This is the Python code I use. This shows exactly the same symptoms as a C++ implementation (but uses less code:)).

Maybe I'm wrong, but when ProgressBar reaches maximum, you reset it and then add + 20 to the maximum. So after all, new maximum for PB is 120. Again, after next song, new max will be 140?!
And one thing is concerning me: how do you looked up the QProgressBar usage
Thanks for your reply. I used htop to look up the memory usage. So it's not only the progress bar's memory usage ofcourse. But you can see the data and res segments rise rapidly.
The test program does indeed grow the maximum. I did this to simulate the changing maximum in my program. It makes little difference on the memory usage actually. It seems that the more steps are taken, the more memory is used.
bq. It seems that the more steps are taken, the more memory is used.
Which is quite obvious when you loading only into memory, without deleting items.
And I hardly believe that QProgressBar is using so much memory. Check out your code, maybe it's something with memory managment when you operating with audio files?
No, this test program will use so much memory. Nothing more than a window with a progress bar. The code above is not from the sound program. It is just to show the symptoms.
I too can hardly believe that QProgressBar is using all this memory but the test program indicates it does.
So I don't have any ideas what can be wrong.
Me neither, hence the forum post. I thank you for your help anyway. | https://forum.qt.io/topic/13231/qprogressbar-high-memory-usage | CC-MAIN-2018-39 | refinedweb | 474 | 69.48 |

I don't know why you want it, Simutrans already has it.
#include "../../display/viewport.h"SQInteger world_change_coord(HSQUIRRELVM vm){ koord k = param<koord>::get(vm, 2); welt->get_viewport()->change_world_position(koord3d(k,welt->min_hgt(k))); return push_instance(vm, "coord", k.x, k.y);}STATIC register_function(vm, world_change_coord, "chag_coord", 2, "");
local pos=coord(95,33) world.chag_coord(square_x(pos.x, pos.y))
Did not saw this thread.Your patch is correct. Instead of returning push_instance(..) it could return SQ_OK. You could also look into functions exported to the script by register_method. This would be much easier.
1) Jumping of view point without user interaction can be irritating. I find it very irritating that the viewpoint changes if one builds a factory.
2) There is no way the user can tell the script `Do it again!`
I see two problems:1) Jumping of view point without user interaction can be irritating. I find it very irritating that the viewpoint changes if one builds a factory.2) There is no way the user can tell the script `Do it again!`
...If the screen would go dark before changing the view point, the player would be more likely to understand that he just teleported, resulting in less confusion. This is especially true if a new window pops up at the same time, explaining what happened....
A black fade-in/out seems very nice to me. Maybe we could use this not only for teleportation, but also for a jump in time?Could be useful in the story based scenario's I'm planning for the future. (if I ever find the time...)
I wish I could do this. If the penguin can do it, why does not simutrans ?.

We have many servers and still want to update them all. The actual way is that any of the sysadmins go from server to server and make a aptitude update && aptitude upgrade - it's still not cool.
aptitude update && aptitude upgrade
I am searching now for a solution which is still better and very smart. Can puppet do this job? How do you do it?
You can use the exec type such as:
exec
exec { "upgrade_packages":
command => "apt-get upgrade -q=2",
path => "/usr/local/bin/:/bin/:/usr/bin/",
# path => [ "/usr/local/bin/", "/bin/" ], # alternative syntax
}
To be honest, I did not try it myself, but I think you just need to create a new module that include such an exec definition.
The apt-get upgrade command is interactive. To make it run quietly, you can add the option -q=2 as shown above.
apt-get upgrade
-q=2
touch
if all your hosts are debian, you can try the unattended-upgrades package.
Here we have been using puppet to manage our debian virtual machines, with puppet we are able to enable and manage unnatended-upgrade configs on all servers.
Recently our team are testing the mcollective tool to run commands on all servers, but to use mcollective ruby skills are needed.
[s]
Guto
I would recommend going for Puppet, facter and mCollective.
mCollective is a very nice framework where you can run commands over a series of hosts (in parallels) using facter as filter.
Add to that a local proxy / cache and you'd be well set for servers management.
Use a tool that is made to run a single command on multiple servers. And by that I do not mean having a kazillion terminals open with Terminator or ClusterSSH, but instead having a single terminal to a management server running a tool suitable for the job.
I would recommend func, Salt or mCollective in this context. If you already have Puppet, go for mCollective (it integrates nicely in Puppet). If you don't, and you have an old Python on your machines, you might enjoy func. If you Python in new, try Salt. All these tools run the command specified at the command line asynchronously, which is a lot more fun than a sequential ssh loop or even doing the same aptitude commands in umpteen Terminator windows to umpteen servers.
You'll definitely love Salt.
So I guess there are many things which contribute to a good solution:
Bandwidth: Basically two alternatives to save bandwidth come into my mind:
Administration: I would configure a parallel shell like PDSH,PSSH,GNU Parallel and issue the command on all clients, if I tested the command previously on an example machine. Then its not very likely that it may fail on all the others.
Alternatively you may consider a cron job on all clients, but then it may fail automatically, so I would prefer the first solution.
If you concern about simultaneity of upgrades you could schedule your commands with at
at
Logging: As with parallel shells you have the possibility to redirect output I would combine stderr and stdout and write it to a logfile.
My own parallel ssh wrapper: classh is an alternative to the various Parallel and cluster ssh tools out there.
You might like it better or you might hate it. There are only three reasons I'm mentioning it here:
subprocess.communicate()
It's extremely simple to write a custom script, in Python, to use classh.py as a module. So it's very easy to write something like:
!#/bin/env python
import classh
job = classh.SSHJobMan(cmd, targets)
job.start()
while not job.done():
completed = job.poll()
for i in completed:
# do something with the classh.JobRecord object referenced by i
# done
# You can optionally do post-processing on the dictionary of JobRecords here
# keyed off the target strings (hostnames)
</code></pre>
That's all there is to it. For example in the nested completed loop you can gather a list of all those which returned some particular exit status or to scan for specific error messages, and set up follow-up jobs to handle those. (The jobs will be run concurrently, default of 100 jobs at any time, until each is completed; so a simple command on a few hundred hosts usually completes in a few seconds and a very complex shell script in a single long command string ... say fifty lines or so ... can complete over a few thousand hosts in about 10 minutes ... about 10K hosts per hour in my environment, with many of those located intercontinentally).
So this might be something you can use as an ad hoc measure until you have your puppet configuration implemented and well testing ... and it's also quite handing for performing little ad hoc surveys of your hosts to see which ones are deviating from your standards in various little ways.
The answer using exec is pretty helpful.
However according to the apt-get manual it's not a good idea to use -q=2 this way (though I have used it for years without problems)
.
I have used a script myself for years, running apt-get the following way:
ssh example.org "apt-get update && apt-get -y upgrade && apt-get -y dist-upgrade && apt-get clean"
Things like puppet and other tools people mentioned sure may work, but it seems like it's overkill for what basically is just mimicking a few commands typed by a human. I believe in using the simplest tool for a specific job, in this case a bash script is about as simple as it gets without losing functionality.
you can use Fabric. Fabric is a Python (2.5-2.7) library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks.
use webmin,,,and use its webmin cluster feature, in which you can add all systems to one webmin console and issue them any command or control all of them from one place.
Or
Use Cluster ssh
Or
PSSH
For years I've been happily upgrading and installing packages using apt-dater. It is lightweight and effective tool for remote package management. It uses screen, sudo and ssh.
For package management apt-dater may be easier solution than configuration management tools.
apt-dater is handy for centralised package management on different GNU/Linux flavours such as Debian and CentOS.
screen
sudo
ssh
Another solution if all your hosts are running Debian (or derivatives) is to use the cron-apt package. But, as suggested per the documentation, a bit of care must be taken.
I'm currently using cron-apt on a dozen of servers to perform all the security updates automatically and unattended. To avoid any unwanted upgrades, I only use cron-apt on servers which runs the Debian stable distribution and I make sure to configure my apt sources so use the distribution name, wheezy, and not its alias (stable).
The specific cron-apt configuration that I use is summarised in one action file: /etc/cron-apt/action.d/5-install
/etc/cron-apt/action.d/5-install
dist-upgrade -y -o APT::Get::Show-Upgraded=true -o Dir::Etc::SourceList=/etc/apt/sources.list.d/security.list -o Dir::Etc::SourceParts="/dev/null"
Any other upgrade, is done manually, using screen or whatever is most appropriate, as it may require manual intervention during the upgrade.

String jumble(String): accepts a string and returns a jumbled version of the original: for this method, jumbled
means that two randomly chosen characters other than the first and last characters of the string are swapped; this method
must use the class, Random. The method must swap two different characters: in other words the two random
indices into the string cannot be equal, cannot be 0, and cannot be equal to the string’s length minus one. So, for example, a
four-letter string MUST result in the returned string having the same first and last characters and have the second and third
characters swapped. Examples of what this method might do: “fist” returns “fsit”, “much” returns “mcuh”, but for longer
strings there will be more possible return values: “spill” could return “splil” or “sipll”. Only ONE pair of letters should be
swapped and strings shorter than four characters are returned unchanged. When the string length is greater than 3, the
original string must never be returned.
I cant seem to get the first and last character to stay the same. It will always scramble the whole word.
DO NOT USE ANY CLASSES only random.
Im a BEGINNER so keep it Easy talk no Array's, appends, etc.
Use substrings, CharAt, length only. if and else for loops are fine while loops are also okay aswell as do/while.

morse_code 0.1.0
Morse Code #
Usage #
Fist depend on the libary by ading this to your package's
pubspec.yaml:
dependencies: morse_code: ^0.1.0
Now inside your Dart code you can import it.
import 'package:morse_code/morse_code.dart';
For this example we're going to use the following morse code string:
final String encodedMessage = '.... . .-.. .-.. --- / .-- --- .-. .-.. -..';
There are two ways to decode a morse code string. Either provide de encoded string as an argument to the constructor, and call the
decode method.
final Morse morse = new Morse(encodedMessage); String decodedMessage = morse.decode(); // Or combine the two, for more compact code: String decodedMessage = new Morse(encodedMessage).decode();
Or provide the encoded string as an argument to the
decode method.
final Morse morse = new Morse(); String decodedMessage = morse.decode(encodedMessage); // Or again combine the two, for more compact code: String decodedMessage = new Morse().decode(encodedMessage);

Using ONLY
! ~ & ^ | +
How can I find out if a 32 bit number is TMax?
TMax is the maximum, two's complement number.
My thoughts so far have been:
int isTMax(int x) { int y = 0; x = ~x; y = x + x; return !y; }
That is just one of the many things I have unsuccessfully have tried but I just cant think of a property of TMax that would give me TMax back. Like adding tmax to itself would be unique compared to all the other integers.
Here is the actual problem:
/* * isTMax - return 1 if x is the maximum, two's complement number, * and 0 return otherwise. * Legal ops: ! ~ & ^ | + * Max ops: 10 * Rating: 1 */ int isTMax(int x) { int y = 0; x = ~x; y = x + x; return !y; }
int is 32 bits so the max signed would probably be 0x7FFFFFFF
As far as I know, there is no way to determine if a particular value is the max value of a signed type without already knowing the maximum value of that type and making a direct comparison. This is because signed expressions experience undefined behavior on overflow. If there were an answer to your question, it would imply the existence of an answer to a serious unsolved problem that's been floating around on SO for some time: how to programmatically determine the max value for a given signed type.
int isTmax(int x) { //add one to x if this is Tmax. If this is Tmax, then this number will become Tmin //uses Tmin = Tmax + 1 int plusOne = x + 1; //add to x so desired input becomes 0xFFFFFFFF, which is Umax and also -1 //uses Umax = 2Tmax + 1 x = x + plusOne; plusOne = !(plusOne); //is x is 0xffffffff, then this becomes zero when ~ is used x = ~x; x = x | plusOne; x = !x; return x; }
Spend 3 hours on this problem. I know this problem comes from csapp's data lab and its newest requirement is
1. Integer constants 0 through 255 (0xFF), inclusive. You are not allowed to use big constants such as 0xffffffff .... * isTmax - returns 1 if x is the maximum, two's complement number, * and 0 otherwise * Legal ops: ! ~ & ^ | + * Max ops: 10 * Rating: 1
So, shift operator(
<</
>> and
0x7FFFFFFF from accepted answer is forbidden now)
Below is my way:
TDD-style:
isTmax(2147483647) == isTmax(0b011111111111...1) == 1 isTmax(2147483646) == isTmax(0b011111111111...0) == 0 isTmax(-1) == isTmax(0b111111111...1) == 0 isTmax(-2147483648) == isTmax(0b100000000...0) == 0
the return should be either
0 or
1. In, c,
! + all nonzero will return
0. So
! is a must, otherwise we cannot guarantee getting
0 for all numbers.
because
0b0111111...1(aka
2147483647) is the only argument which should make
isTmax return
1 and
2147483647 + 1 should be
10000000...0(aka
-2147483648)
0b011111111...1 xor 0b1000000000...0 is
0b11111111111...111. Because we must use
!, what we hope to see is
0(aka
0b0000000000000...0). Obviously, just apply logic not(aka
!) to
0b1111111...1), then we will get
0b000000000000):
!(~(x ^ (x + 1))
let's printf it
void print(int x) { printf("%d\n", !(~(x ^ (x + 1)))); } int main() { print (2147483647); print(2147483646); print(-1); print(-2147483648); }
1
0
1
0
Not bad, only
-1 doesn't work as we expected.
Let's compare
-1 and
2147483647
11111111111111111111111111111111
01111111111111111111111111111111
We can find
-1 + 1 = 0 while
2147483647 + 1 = -2147483648. Emphasize again, what we want is diff
-1 and
2147483647, because both of them return
1 as above shows. Look back to the protety of logic not in c: all nonzero will return 0, so
!-2147483648 == 0 and
!(-1 + 1) != 0. Just modify left part of
x ^ (x + 1)(
x) into
x + !(x + 1). If x is
2147483647,
x + !(x + 1) will equal to
x.
Run again:
void print(int x) { printf("%d\n", !(~( x + !(x + 1) ^ (x + 1)))); } int main() { print (2147483647); print(2147483646); print(-1); print(-2147483648); }
1
0
0
0
Done!
No shifts solution. Realizing to take advantage of the property that
!(0b01111 + 1 = 0b10000) = 0 and
!(0b11111 + 1 = 0b00000) = 1 is particularly tricky. This problem took me a long time.
/* * isTmax - returns 1 if x is the maximum, two's complement number, * and 0 otherwise * Legal ops: ! ~ & ^ | + * Max ops: 10 * Rating: 1 */ int isTmax(int x) { int a = ~((x + 1) ^ x); int b = !(x + 1); int c = !(a + b); return c; }
Something like this perhaps? 0x7FFFFFFF is the maximum positive signed 32 bit two's complement number.
int isTMax(int x){ return !(x ^ 0x7FFFFFFF); }
I am not sure, you may need to cast it to unsigned for it to work.
#include <stdio.h> #include <stdlib.h> int test(int n) { return !(n & 0x80000000) & !~(n | (n + 1)); } // or just effectively do a comparison int test2(int n) { return !(n ^ 0x7fffffff); } int main(int ac, char **av) { printf("is%s TMax\n", test(atoi(av[1])) ? "" : " not"); return 0; }
if it is Tmax : 011111.....
then we xor it with 10000....
we get 11111....
then we ~ to get all 0s = 0 , !0 we get 1:
int isTmax(int x) { return !(~((1 << 31) ^ x )); }

Adding support for call-by-need (aka lazy arguments) using scalameta:
def foo(cond: Boolean)(bar: => String) = {
lazy val lazyBar = bar
if (cond) lazyBar + lazyBar
else ""
}
foo(true){ // some computation ... }
This looks ok but can it be abstracted so we don’t have to define these local lazy values? This would be useful especially when dealing with multiple lazy arguments.
In this blog I’m going to present a simple solution using scalameta macro annotations to remove the boilerplate required for lazy arguments.
Macro annotations to the rescue
I have defined a macro annotation
@WithLazy which implements call-by-need arguments. We use
@Lazy to mark the parameters we want to evaluate lazily (in our case it's
elem). Let's have a look at the example bellow:
@WithLazy def lazyFill[T](t: Int)(@Lazy elem: T): Seq[T] = Seq.fill(t)(elem)
Let’s call the method with zero and a non-zero
t:
lazyFill(0) {
println("call-by-need")
1
} //prints nothing, yields: List()
lazyFill(4) {
println("call-by-need")
1
}
// prints only once: call-by-need
// yields: List(1, 1, 1, 1)
As we can see
elem is evaluated at most once: when
t > 0
elem is evaluated once and when
t == 0
elem doesn't get evaluated.
If you want to try out this example feel free to skip to the Installation section.
Implementation details
The first and current implementation is relatively simple and consists of the following steps:
- Define the
@WithLazymacro annotation which implements the call-by-need functionality and
@Lazyto mark the parameters to be evaluated lazily.
- All the parameters annotated with
@Lazyare changed to be call-by-name.
- The method is wrapped with another one with the same signature.
- Define local lazy values in the outer method for each
@Lazyannotated parameter with its value.
- The inner method name is added the “$Inner” suffix.
- In the outer method body call the inner method with the corresponding local lazy values (if any).
After applying the AST transformation the method we defined above is transformed into:
def lazyFill[T](t: Int)(@Lazy elem: => T): Seq[T] = {
def lazyFill$Inner[T](t: Int)(@Lazy elem: => T): Seq[T] = Seq.fill(t)(elem)
lazy val elem$Lazy: T = elem
lazyFill$Inner(t)(elem$Lazy)
}
The implementation of the
@WithLazy macro annotation can be found here.
Design decisions & challenges
You may probably wonder why did I choose this approach instead of declaring the local lazy values and rewrite the function body tree to use these values instead. Currently, macro annotations support the syntactic API only which in a nutshell means that you get the AST as is, with no context, no types inferred, just the plain AST. Using the syntactic API only makes the scoping very challenging, which in my case would happen when having nested methods. This was one of the main reasons I ended up using the method wrapping approach. This approach was fairly easy to implement and it also gave me a nice starting point for further experiments.
Also, it was quite challenging to check which argument is annotated with
@Lazy. Because
@Lazy != @lazyargs.Lazy I had to make sure that I check the parameters for being annotated with
@Lazy,
@lazyargs.Lazy,
@com.tudorzgureanu.lazyargs.Lazy or
_root_.@com.tudorzgureanu.lazyargs.Lazy. Luckily, I was not the only one facing this problem and I was able to find a suggestion from @olafur which helped me to determine all the parameters that were annotated with
@Lazy. Of course, I could just generate a list of all the sub-packages and then check if there are any parameters annotated with any "version" of
@Lazy from that list. Perhaps, I should give it a try. Unfortunately, if the import was renamed there is nothing you can do about it.
The good news is that def macros are going to support the Semantic API although there is no ETA for making macro annotations to support the Semantic API.
Future plans
- Probably the first improvement would be adding a naive lazy implementation that doesn’t rely on lazy values, which are advertised to be resource consuming (it uses locks to provide thread safety). It will trade thread safety in exchange for performance. As we most of the time write functions whose parameters aren’t involved in concurrent computation it would make sense to have this low-overhead alternative as the default implementation and the tread safe implementation enabled by another annotation (e.g.
@volatilelike in Dotty).
- Add more test cases that cover various ways of defining functions (e.g. nested functions). This should bring more safety when doing further experiments with this library.
Installation
After experimenting enough with scalameta I decided to release the macro annotation as a small library. It’s not production-ready (it might never be, although I will still spend some time improving it) so use it at your own risk fun.
You will need to use Scala
2.11.8+ or
2.12.x.
- Add the bintray repo resolver for this project:
resolvers += Resolver.bintrayIvyRepo("tudorzgureanu", "generic")
- Add the dependency to this project:
libraryDependencies += "com.tudorzgureanu" %% "scala-lazy-arguments" % "0.1.0"
- Add scalameta paradise compiler plugin and scalameta dependency:
addCompilerPlugin("org.scalameta" % "paradise" % "3.0.0-M8" cross CrossVersion.full)
libraryDependencies += "org.scalameta" %% "scalameta" % "1.8.0" % Provided
Conclusions
In this blog post I have presented a relatively simple solution for adding support for call-by-need arguments without boilerplate. It is implemented using scalameta macro annotations. Hopefully, the support for
lazy keyword will be extended so we can apply it on method parameters as well. The full code is available on github.
Happy meta-hacking!

The MCP3008 ADC is pretty cheap and easy to use with the Pi, so I bagged myself one.
Raspberry Pi Spy has got a really good tutorial on setting up an MCP3008 to read analogue sensors which I followed to get everything running, but the code didn't fit my needs so I created a python class for reading data from the MCP3008.
from spidev import SpiDev class MCP3008: def __init__(self, bus = 0, device = 0, channel = 0): self.bus, self.device, self.channel = bus, device, channel self.spi = SpiDev() def __enter__(self): self.open() return self def open(self): self.spi.open(self.bus, self.device) def read(self): adc = self.spi.xfer2([1, (8 + self.channel) << 4, 0]) data = ((adc[1] & 3) << 8) + adc[2] return data def __exit__(self, type, value, traceback): self.close() def close(self): self.spi.close()
The class is really easy to use, using Python's 'with' statement to control it:

It is quite good at this. It will know what you have set for the clocks and will set up the baud rate correctly. Then you can look a the code. | https://community.nxp.com/thread/45833 | CC-MAIN-2019-22 | refinedweb | 188 | 82.85 |
BPython Lives!!!
In January, I suggested it would be trivial to write a preprocessor that would accept a version of python which delimited blocks with braces instead of indentation.
Ok, almost, I suggested #{ and #} as delimiters.
Well, I had a few minutes free today, and here it is, a functional BPython->Python compiler, so to speak.
Here's the kind of imput it takes (notice how it's not indented at all:
def factorial(n): #{ if n==1: #{ return 1 #} else: #{ return n*factorial(n-1) #} #} for x in range(1,10): #{ print x,"!=",factorial(x) #}
And it produces this (I am not happy with the indenting of the comments, but who cares):
def factorial(n): #{ if n==1: #{ return 1 #} else: #{ return n*factorial(n-1) #} #} for x in range(1,10): #{ print x,"!=",factorial(x) #}
As you can see, this is both a legal Python and a legal BPython program ;-)
It has some problems, like not working when you use a line like this:
#{ x=1
But hey, it is python with braces.
Here's the code. I predicted 30 lines. It's 34. And it's 99% a ripoff of Ka Ping Yee's regurgitate.py which you can find all around the web.
#!/usr/bin/env python import tokenize, sys program = [] lastrow, lastcol = 1, 0 lastline = '' indlevel=0 def rebuild(type, token, (startrow, startcol), (endrow, endcol), line): global lastrow, lastcol, lastline, program,indlevel if type==52 and token.startswith ("#{"): type=5 indlevel+=1 if type==52 and token.startswith ("#}"): type=6 indlevel-=1 line=" "*indlevel+line.lstrip() startcol+=indlevel*2 endcol+=indlevel*2 # Deal with the bits between tokens. if lastrow == startrow == endrow: # ordinary token program.append(line[lastcol:startcol]) elif lastrow != startrow: # backslash continuation program.append(lastline[lastcol:] + line[:startcol]) elif startrow != endrow: # multi-line string program.append(lastline[lastcol:startcol]) # Append the token itself. program.append(token) # Save some information for the next time around. if token and token[-1] == '\n': lastrow, lastcol = endrow+1, 0 # start on next line else: lastrow, lastcol = endrow, endcol # remember last position lastline = line # remember last line tokenize.tokenize(sys.stdin.readline, rebuild) for piece in program: sys.stdout.write(piece)
So, all of you who dislike python because of the lack of braces and the significant whitespace:
BPython has no significant whitespace, and braces are mandatory.
Enjoy coding!
It would be pretty straightforward to just build this functionality into Iron Python - with the C# source being readily available. That way you could get your brace delimited Python up and running on machines with the .NET Framework (or Mono) without a pre-processor.
Maybe I didn't make it clear enough that I think brace delimited python sucks ;-) | https://ralsina.me/weblog/posts/P347.html | CC-MAIN-2020-45 | refinedweb | 450 | 57.77 |
Subject: Re: GR_Image is raster specific

Justin,
IIRC, what you're seeing here is about how far Matt Kimball got when he was
thinking about adding SVG support last summer. As you've noticed he did
most of the required code refactoring, but not quite all of it.
I really like the approach you've proposed here.

Yes, yes, yes. That's exactly what I've been hoping for too.

Hmm. I hadn't thought of moving them out-of-flow like that, but I think I
like it. So long as we know dimensions for that IMAGE box in the layout,
the fact that it's a forward reference shouldn't be a problem.

Agreed. Being able to handle SVGs as a standalone entity (just like we do
now for raster images) is a desirable feature.
Do we want to figure out the switching mechanism for other raster image
formats (JPG, BMP, etc.) first, so we can take advantage of it here?

Embedding one kind of XML inside another is exactly what namespaces are for,
and knowing James, I suspect that the mechanisms he's added to expat are
quite clean.
Sounds like the first step will be to upgrade our expat module in CVS to the
latest release. Do you feel comfortable doing that diff-merge (IIRC, we've
got a few BEOS-specific tweaks), or should we find someone else to take care
of that?

Hi all,
I meet a problem on populating array properties...
here is the detail description:
public class User {
String [] phone;
public String[] getPhone(){
return phone;
}
public void setPhone(String[] phone) {
this.phone=phone;
}
}
public class UserAction {
private User user=new User();
public User getUser(){ return user;}
public void setUser(User user) { this.user=user;}
public String execute() {
// user.getPhone() always return null...
}
}
And i have a jsp which will submit a list of phone to the action class
<form name=xxx action=xxx>
<input type=text
<input type=text
<input type=text
<input type=submit name=submit value=submit/>
</form>
after the form is submitted... the action class is called, however the list
of phone can't be populated to the user object in the UserAction class...
i have tried if the phone is not a array type.. the property is populated to
the user object ...
any suggestion for the issue?
thx alot! | http://mail-archives.apache.org/mod_mbox/struts-user/200806.mbox/%3Cf3357190806011216r7ee2d241j798aa6cb3f8725ea@mail.gmail.com%3E | CC-MAIN-2014-49 | refinedweb | 153 | 57.67 |
