SustainabilityOpen is an initiative to make the built environment a better place. By providing open-source tooling to the building industry we hope to stimulate that every building and structure will become more sustainable. We are also trying to deploy new and quantitative approaches to assess sustainability in an open-source environment.
By providing you, in case you are representing a company or yourself, with an open-source, free-to-use software framework which you can use to build your own design, analysis and assessment tools for sustainable design, there really is no reason anymore why you shouldn’t design in a sustainable manner, or at least analyse and assess your building. The mission is to collaboratively research and build a toolkit that includes many analysis and assessment methods, many components that help with automated design and link to many mainstream software applications, such parametric software applications, BIM applications and geometrical design software.
How does it work?
SustainabilityOpen (or sustainability-open) consists of
- The framework
- Implemented components
The framework is provided by us for you to use, but it doesn’t do a lot. It only lays the computational infrastructure for others to use. You will need implemented components to use the framework. These components you are either build yourself or download from the internet if they are build by others.
The framework consists of a number of abstract classes, which we call components, which need to be overridden in order to do something. There are three types:
- Designers: Designers produce a ‘design’ on which the analysis and assessment components can work.
- Analysis components: the analysis components take in a number of design components that aggregated contain the design and perform one or more analyses on the design. The analysis components produce an output for assessment components to use. An example could be an analysis that adds up all materials into their total quantities.
- Assessment components: The assessment components take a number of analysis outputs in and perform one or more assessments to produce an assessment result. An example could be an assessment that calculates the total embodied energy in the design from the material quantities.
At the moment there is one special helper component in the framework, the QTOAnalysis, which actually does some work. QTOAnalysis stands for Quantity Take Off Analysis. We have added this component to the framework as we expect that almost any project will use this component. In the future more helper components might be added to the framework.
Below a diagram shows an overview over the framework and the areas where plug-ins can be added. For more information, refer to the documentation.
The framework and components have been designed to be build against Rhinoceros 5.0 and Grasshopper 9. You will need these applications to use the framework.
You can find the source code on Github in these repositories:
Other repositories that will become available soon are:
But you are of course welcome to add new functionality by adding your own plug-in projects. If you drop us an e-mail, we will add them to our component list.
To install the tools, simply download the latest zip file, unzip it in a directory of your choice and point your Grasshopper installation to that directory. The components will become available under the SustainabilityOpen tab in Grasshopper.
Documentation can be found on this page and in the Github repositories.
The sustainability-open framework is released under the Apache 2.0 license.
The reasoning behind releasing the framework under the Apache 2.0 license is that we want to encourage companies and individuals to build their own component plug-ins and do not want to scare them off with a restrictive license that forces you to give away all your secrets. Of course, we would appreciate it if you have improvement suggestions for the framework to let us know or even better submit some code back to us. Under this license you are also allowed to fork the code, but we of course would highly appreciate if you don’t. We are putting in the hard work to make sure that everybody can benefit from this code. Forking would not make this very efficient for everybody.
The so-bemnext-* plug-ins will be released under a different open-source license with copyleft (to be announced).
In the so-bemnext-* repositories we are contributing our research results. We are happy for you to use those and/or extend them, but please note the copyleft character of the license. As we want to help science forward, we require that if you build on top of these plug-ins, that you help science a step further by sharing back your code.

DaveH (NEM Ventures):
I am posting this on behalf of @kaiyzen and the development team from a couple of updates on other platforms:
We are working on how best to streamline these communications going forward but I wanted to err on the side of openness and getting the information out asap.
Any questions please ask them here or on the Slack thread
Telegram (25th April)
The 0.9.4.1 server build was released yesterday, that triggered final updating and verification of tooling and new testnet setup.
We completed the base testnet setup last night, today we are doing another cleanup pass on testing and a second round of nodes added. Once we get through that we will post an update and assuming we don’t encounter anything coming up we will post link references to new network and release the tooling
Update thread from Slack (26th April)(https://nem2.slack.com/archives/C9E7N7H1N/p1587886005040100 20):
The 0.9.4.1 server has been released and a new test network has been started for it
Starting with 0.9.4.1 all peers, and clients talking to peers, will use TLS as the means of handshaking and communications. With this change nodes identities are based on their certificates vs the traditional setting of the identity boot key in the server configuration file.
The team is rolling out the pieces. For those that are interested on the development side an initial set of api endpoints are available, these will be added to in the coming week:
You can use the latest version of the sdk and cli to connect to these endpoints.
NOTE: due to a different network identity and nemesis creation, existing users of the desktop wallet will have issues trying to perform transactions unless you wipe your data from your wallet and start fresh with a new set of 941 network endpoints. A wallet update should be out in the next week to help address caching issues when trying to use the same test wallet across networks that are different
For those experimenting with local test networks the bootstrap tool has been updated to support the latest images, its in beta and will have minor updates applied in the coming weeks
NOTE: For those who have been running test network nodes you will perform the usual routine of wiping your environment to switch to running nodes on the new network. The team will be releasing the test network bootstrap tool early this week

Functional programming may be very distinctive from critical programming. The most important variations stem from The truth that useful programming avoids Unintended effects, which are Utilized in crucial programming to carry out condition And that i/O. Pure useful programming wholly helps prevent side-effects and provides referential transparency.
Omitting kinds is normally regarded a bad follow in method parameters or system return sorts for public APIs. Whilst utilizing def in a local variable is not really an issue as the visibility with the variable is limited to the strategy itself, even though set on a technique parameter, def will likely be transformed to Object in the tactic signature, which makes it tough for users to find out that's the anticipated type of the arguments.

On Each and every operate call, a duplicate of the details framework is established with whatsoever variances are the result of the perform. This is often called 'point out-passing style'.

Person re-identification is an emerging problem in visual surveillance, deals with maintaining entities of individuals while they traverse various locations across a camera network. From a visual perspective re-id is challenging due to significant changes in visual appearance of individuals in cameras with different pose, illumination and calibration.
Researchers approaches these difficulties with designing of distinctive view-invariant person representations, and learning of effective distance/similarity metrics. Similar to the two different focuses, we propose two algorithms: one designs a novel appearance model that takes into the visual pattern co-occurrence across different views; and the other formulates the problem in a global structured matching setting.
Person Re-identification with Visual Word Co-occurrence Model
Summary: We propose a novel visual word co-occurrence model to deal with the appearance variations across different views. We first map each pixel of an image to a visual word using a codebook, which is learned in an unsupervised manner. The appearance transformation between camera views is encoded by a co-occurrence matrix of visual word joint distributions in probe and gallery images. Our appearance model naturally accounts for spatial similarities and variations caused by pose, illumination & configuration change across camera views. Linear SVMs are then trained as classifiers using these co-occurrence descriptors.On the VIPeR and CUHK Campus benchmark datasets, our method achieves 83.86% and 85.49% at rank-15 on the Cumulative Match Characteristic (CMC) curves, and beats the state-of-the-art results by 10.44% and 22.27%.
Illustration of codeword co-occurrence in positive image pairs (i.e. two images from different camera views per column belong to a same person) and negative image pairs (i.e. two images from different camera views per column belong to different persons). For positive (or negative) pairs, in each row the enclosed regions are assigned the same codeword.
Person Re-identification via Structured Matching
Summary: From a visual perspective re-id is challenging due to significant changes in visual appearance of individuals in cameras with different pose, illumination and calibration. Globally the challenge arises from the need to maintain consistent matches among all the individual entities across different camera views. We propose PRISM, a structured matching method to jointly account for these challenges. We view the global problem as a weighted graph matching problem, and learn the edge weights (pairwise similarity scores) based on the co-occurrence of visual patters in the training examples. These co-occurrence based scores in turn account for appearance changes by inferring likely and unlikely visual co-occurrences appearing in training instances. We implement PRISM on single shot and multi-shot scenarios. PRISM uniformly outperforms state of the art by as much as 10%-30% in matching rate while being computationally efficient.
This is an overview of our method, PRISM, consisting of two levels where (a) entity-level structured matching is imposed on top of (b) image-level visual word deformable matching. In (a), each color represents an entity, and this example illustrates the general situation for real world re-id, including single-shot, multi-shot, and no matches. In (b), the idea of visual word co-occurrence for measuring image similarities is illustrated in a probabilistic way, where l 1 , l 2 denote the person entities, u 1 , u 2, v 1 , v 2 denote different visual words, and h 1 , h 2 denote two locations.

"Has achieved whatever work it was in him to do"
But in an old man who has known human joys and sorrows, and has achieved whatever work it was in him to do, the fear of death is somewhat abject and ignoble.
(Bertrand Russell How to grow old from Portraits from Memory; emphasis mine)
What is the purpose of the structure "it was" in the sentence? Does "it" refers to "work"?
How does the sentence compare to the following formulations? (Are they correct? Why? How are they different from the original sentence?)
has achieved whatever work was in him to do
has achieved whatever work in him to do
It's the same it in: "It's just not in me to finish this job today." So it's more like the drive, resolve, energy, gumption...
@Jim I thought "it" in your example refers to "to finish this job today"? So the sentence is an alternative formulation of "To finish this job today is just not in me"?
I've never thought about it like that. I've always thought of it as: The resolve/energy is just not in me to finish the job today. Or alternatively: I don't have the energy to finish the job today. Your formulation makes use of metonymy so while it ultimately means the same, it's a different parse.
But in an old man who has known human joys and sorrows, and has
achieved whatever work it was in him to do, the fear of death is
somewhat abject and ignoble.
I would interpret "whatever work it was in him to do" to mean his life's purpose. And "the fear of death is somewhat abject and ignoble" is saying that the fear is abject (self-abasing) and ignoble (shameful). In other words, this old man should consider the fear of death to be an unworthy emotion, one which he chooses to not have (to the extent that that's possible).
Russel goes on to say:
The best way to overcome it -- so at least it seems to me -- is to
make your interests gradually wider and more impersonal, until bit by
bit the walls of ego recede, and your life becomes increasingly merged
in the universal life.
The "it" to be overcome here is apparently the fear of death.
The number 2 formulation is not correct. The "it was" is the "to be" verb referring to the work. There needs to be such a "to be" verb in the sentence referring to the work.
It could be the work that "was there" for him to do, or that "there was " for him to do etc. You can state it as past or past perfect or future as needed.
You may think of the work as his goal or objective.
First we should say that English allows for multiple ways to say the same thing.
As mentioned @Eliot's answer, #2 is simply incorrect English.
However, #1 to me does not convey quite the same flavor as Russell's phrase does, which comes off as a bit more poetic. The phrase "whatever work was in him to do" works well enough, but "it was" to me tries—in the context given—to add a bit of wistfulness, leaving it possible to think that had the old man not grown old and tired, he'd have done more work. The "it" has left him.

great addition. Missing a test case though, which would probably trigger @aaron.ballman scenario
Mon, Jul 4
I'm fine with these tests has they reflect current implementation. But beware that ubsan and -Warray-bounds don't behave the same wrt. FAM, which I find disturbing. I'll discuss that in another review.
Fix handling of ConstantArrayType, thanks @aaron.ballman for the hint.

Wed, Jun 29
@aaron.ballman : I agree with most of your suggestion except the one below that I annotated accordingly
And note that with current clang, the behavior I describe here is not uniform across clang code base :-/
Code updated to take into account two situations:
Tue, Jun 28
GCC and Clang don't have the same behavior wrt. macros-as-abound and standard-layout-requirement, see https://godbolt.org/z/3vc4TcTYz
I'm fine with keeping the CLang behavior, but do we want to keep it only for level=0, and drop it for higher level (this would look odd to me).
Mon, Jun 27
Take review into account + add C++ test file.
oh, and I landed that one while forgetting to link it to phabricator, this patch landed as 27fd01d3f88c1996fc000b6e139b50a600879fde
@RKSimon: I don't track the origin of the change, I can't tell...

Thanks @MaskRay for the quick patch!
Take review into account : rework indentation, style cleaning and be more accurate about bounds reporting

Activate -Warray-parameter on -Wmost but disable it by default

Hey Sam, any update on this one? How can I help?
Tue, Jun 21
Follow @nikic approach there, it's clean and simple. Just fix a little edge case in the finish routine. Note that I could have checked the size of the cleanup vector, but I felt like a more explicit approach would be better.
@kees does the new version looks good to you?

LL: Oh, he bit the dust yesterday. I found him floating in the tank. I'm really bummed out about it.
LH: 你的金鱼怎么了？Bit the dust? Bit是bite的过去时。意思是：咬； 那dust是尘土的意思。咬尘土？ 噢，你是说你的鱼死啦？
LL: That's right! That fish was a few years old, so I think he might have just died of old age.
LL: I'm thinking about going to buy a new fish today, but I want to clean out the tank first. I don't want the new fish to bite the dust, too.
LL: It's possible. I really don't want to take any chances.
LH: 对，一条鱼价钱也不便宜，可别冒风险。对了，Larry，你知道吗？John的奶奶几天前去世了，那我是不是能说：she bit the dust the other day。
LL: Wait a second, Li Hua, I don't think you want to say that your friend's grandma bit the dust. It's not very polite or respectful.
LH: 噢，bite the dust这个说法用在人的身上是不礼貌的！那我还真是得小心。
LL: It's okay to say my fish bit the dust or some bad guy in a movie bit the dust, but you probably don't want to say that about your friend's family member.
LH: 嗯，我懂了。To bite the dust可以指鱼，可以指电影里的坏蛋，可是千万不要在朋友的家人去世的时候用这个说法。
LL: You've got it! Now let's go buy a fish.
LH: Larry, 你为什么不买那条鱼？它的鳍好大而且颜色好漂亮！我从来没见过色彩这么鲜艳的鱼呢！
LL: Yeah, he is kind of funky. I don't think I've ever seen another fish like that either.
LH: 等等，什么是funky? 是不是很酷的意思?
LL: Funky has several meanings, but in this case, it means cool, unique, and unusual.
LL: Hold on, that funky little fish is pretty expensive. Why don't we get a cheap little goldfish instead?
LL: I happen to like goldfish. I can buy one of those goldfish with the funky bubbles behind its eyes.
LH: 你是说那条眼睛后面长两个大球的金鱼呀？我还是喜欢那条很漂亮的鱼，那条funky fish。
LL: Well, I appreciate your opinion, but this is going to be my fish.
LL: Yeah, he definitely has his own sense of style. It looks as though he's here to buy a fish, too.
LL: That's a possibility. Now, come on, forget about that fish and help me pick out a goldfish, the funkier the better.
今天李华学到两个常用语。一个是bite the dust, 就是死掉的意思，不过通常不用在人身上，因为那样说不太礼貌。另一个常用语是funky。意思是很酷、很独特。

(Mbps), how long does it take to transfer 1 bit?
μsec to transmit each bitYou can also think of each bit on a network as being a pulse of some width. The more sophisticated the transmission/receiving technology, the narrower each bit can become. Other factors (e.g., software) affect the throughput as well.

How is this calculated
-switched networks provide service by setting up a
total path of connected links from the origin to the destination host.
A control message is first sent to setup a path from the origin to the destination. (A return signal informs the origin that data transmission may proceed.)
Once data transmission starts, all channels in the path are
, and the entire path remains allocated to the transmission (whether or not it is in use).2. Packet-switchednetworks decompose messages into small pieces called packets. These packets are each numbered and make their way through the net in a store-and-forward fashion.
Links are considered busy only when they are currently transmitting packets Recall
: Two types of Switched NetworksSlide10
Circuit & Packet Switching Performance Issues
Header overhead (i.e., the amount of "extra" information that must be sent along with the data to ensure proper transmission)
For large amounts of data:
circuit switching <= packet switching
(i.e., the amount of time it takes data from the time it enters the network until it arrives at its' destination)
For short and bursty messages: packet switching has the lowest delay. For long, continuous streams of data: circuit switching has the lowest delay.Slide11

One of the key components in any of the Windows Server operating systems is the File Replication Service (FRS). The File Replication Service has two main responsibilities: It keeps replicas within a Distributed File System (DFS) consistent, and it replicates Active Directory (AD) updates between domain controllers. In order to get the most benefit out of FRS and be able to troubleshoot it should problems arise, you need to understand how FRS works. Here’s what you need to know.
Before I get into the hard-core inner workings of FRS, I want to go over a few basics of how FRS works. As you know, FRS is used to keep replicas up to date within a DFS tree and to keep the AD information within domain controllers synchronized. Technically, AD replication and file replication are two different mechanisms. However, they work so similarly that if you understand how one works, you’ll basically understand the other. For the purposes of this article, I’ll focus on file replication.
Like AD replication, file replication uses a multimaster model. This means that updates can occur independently on any server within the domain. There’s no need for the updates to be made to a primary server and then be distributed out to other servers.
Two other important ideas you need to be aware of are that FRS is multithreaded, and that FRS works at the file level. This means that individual changes within a file are not replicated. If even one byte within a file is changed, the entire file must be replicated. Since the process is multithreaded, though, FRS is able to replicate changed files to multiple computers simultaneously. You never know what order changed files will arrive in, or which system the updated files will arrive at first. Although the replication cycle is scheduled, for all practical purposes, the update order is random.
So what happens when a replicated file changes? If a user modifies a file that is configured to be replicated to one or more other servers, FRS waits until the user closes the file before it does anything. If a user still has a modified file open when a replication cycle occurs, the file will not be replicated because it’s considered to be unmodified until it has been closed.
After the user closes the modified file, the NTFS file system makes a record in its change journal that the file has been modified. FRS relies on this change journal for its information. The nice thing about this is that even if the server goes down unexpectedly, replication of modified files is still possible when the server comes back up because FRS gets its file modification information from the change journal, which is a part of the file system.
Next, FRS waits for the next scheduled replication cycle to occur. When it does, FRS replicates the changed files to the rest of the servers in the replication set through the use of the TCP/IP protocol. To ensure secure communications, FRS relies on an authenticated Remote Procedure Call (RPC) with Kerberos to encrypt the files before they are transmitted.
Whenever you’re dealing with replica files, there’s a chance for conflicts to occur. For example, suppose the same file exists on Server A and Server B. It’s entirely possible that two users could modify the two different copies of the file at the same time. FRS does nothing to lock the other replicas when a replica is being modified. Furthermore, if two files are simultaneously modified, FRS does not attempt to merge the modifications. Instead, the most recent modification takes precedence.
FRS has a very interesting way of determining which file is the most recent. Suppose User 1 modified a file on Server A, and slightly thereafter, User 2 modified the same file on Server B. Obviously, User 2 made the most recent modification, and that’s the one that should take precedence. However, because of replication latency, it’s possible that User 2’s modification could reach Server C before User 1’s modification. You really don’t want Server C to consider User 1’s modification to be the most recent, so FRS uses what’s known as the 30 Minute Rule.
The 30 Minute Rule basically states that if the replication cycle tries to overwrite a file on a replica with a modified version, and one version is at least 30 minutes older than the other, then the newer file takes precedence and the older file is discarded. If, on the other hand, the time stamp on the two files is within 30 minutes, then FRS looks at the file’s version number to try to resolve the conflict.
The version number is incremented by one every time the file is modified. In the case of DFS, though, it’s entirely possible that two different versions of the same file could have the same version number. If this happens, FRS looks at the time stamp again but ignores the 30 Minute Rule, and the file with the most recent time stamp takes precedence.
By using this algorithm, the file modified by User 2 would overwrite the replica on Server B because it is newer. However, when the file modified by User 1 arrived, the time stamps and versioning would prove that although the file arrived later than the file modified by User 2, the file was actually modified earlier. This means that the file modified by User 2 is newer, and the file modified by User 1 would be discarded.
Before I move beyond the basics, I should point out that there is no user interface specifically for the FRS. AD replication is an automated system process. DFS file replication is controlled by the Distributed File System snap-in for the Microsoft Management Console.
FRS operation in detail
Now that you have a basic understanding of how FRS works, I want to discuss FRS operation in greater detail. Let’s start with how FRS maintains a list of replication partners. This is one of the few areas where DFS and Active Directory differ. With AD, all domain controllers are automatically considered replication partners. The Knowledge Consistency Checker (KCC) runs periodically and checks the replication partners (domain controllers) to be sure that they’re still online. If the KCC detects a failed connection or a domain controller is down, the KCC will automatically adjust the replication topology to the optimum configuration.
DFS, on the other hand, doesn’t use the KCC. Instead, you must define replication sets through the Distributed File System Snap-In. A replication set consists of computers and links. Replication links can transmit data in only one direction.
For example, if a replication link existed from Server A to Server B, data could flow only from A to B. If you wanted replication data to also be able to flow from B to A, you’d have to create a second link going in the opposite direction. Being that replication links are unidirectional, Microsoft refers to the server that’s sending the data as the Outbound Partner, while the server receiving the data is referred to as the Inbound Partner.
Now, let’s take a quick look at the overall replication process. When a user modifies a replica, the NTFS file system makes an entry in its change journal at the time when the file is closed. Meanwhile, FRS is monitoring the change journal. FRS makes a list of closed files and then filters the list so that it looks only at those files that exist within replicated shares.
Next, a mechanism—the aging cache—comes into play. The aging cache is a three-second timer. Its sole purpose is to keep the FRS from being bogged down when a file is rapidly changing. The aging cache ensures that a rapidly changing file is staged for replication only once every three seconds.
The server writes an entry into the inbound log regarding the change. The inbound log is normally used to keep track of modifications that have occurred on other replication partners so that those changes may be applied locally. The inbound log is basically used to tell the server about the change. It records the filename and the date/time of the modification.
However, although the change occurred to the local replica, it’s still written to the server’s inbound log. An entry is also written in an ID table so that the system can recover itself if a crash occurs. I’ll talk more about this table later on.
The server then writes a copy of the changed file to a staging directory. This directory is an area on the local server that is designed to temporarily store files until they can be replicated to the other servers. The reason that data is staged, rather than simply being replicated from its original location, is that the original file could be accessed (locked) by a user at any time. On the other hand, by transmitting a copy instead of the original file, Windows can guarantee that the copy is not in use. While in the staging area, Windows also encapsulates the file and replicates the NTFS attributes that go with the file.
Next, the server updates its outbound log. The outbound log is a log file containing a list of outbound replicas. Depending on the network topology, the items in the outbound log can be generated locally or by an inbound partner. An inbound partner would be able to place items in the server’s outbound log if the server were responsible for retransmitting the file to another replication partner. Finally, the server transmits a change notification message to another replication partner.
The other server receives the change notification and uses an algorithm to decide whether the changed file is newer than its current version. Assuming that the changed file is newer, the server asks the computer containing the changed file for the file. When the file is received, the server copies the file to its own staging directory while it updates its outbound log file. The server uses a staging area so that users do not see the file as being locked while it is being downloaded from the other server. Finally, the received file is reconstructed within the staging area and then moved to its final location.
In the section above, I mentioned several log files and various tables. Understanding these tables is crucial to being able to use the various troubleshooting tools effectively. All of the various logs and tables are stored in Microsoft Jet Database format.
The default location for these databases is %SYSTEMROOT%\NTFRS\JET\NTFRS.JDB. The JDB file is the actual Jet database file that contains the various tables. There are five tables in all, and each replication partner has its own independently maintained copy of these tables:
- Connection table
- Inbound log
- Outbound log
- Version vector table
- ID table
It has been my experience that most of the time when replication breaks down, it’s the result of a failed link or a server that’s down. However, when these simple causes don’t apply, the problem is almost always related to information found in one of these tables.
The first table in the database file is the Connection table. This is the table that keeps a record of all the inbound and outbound replication partners. Each link or partner connection uses a separate record within this table.
The next table is the inbound log, which contains all the change orders that have not yet been processed. This table’s records include the filename, the GUID of the change order, object ID, parent ID, event time, and version number.
The outbound log stores all of the change orders that are to be sent to other replication partners. The records structure of the outbound log is identical to that of the inbound log.
The fourth FRS table is the version vector table, which is used to determine how up to date each replica is. This table is updated every time an FRS context is replicated and whenever the outbound log fills up and wraps (the outbound log uses circular logging because it can grow to be very large if one of the replication partners is down).
The final table is the ID table, which maintains a list of all the files in the replica set. Records in the ID table include the filename, GUID, parent file ID, object ID, parent object ID, event time, and current version number.
It’s not as bad as it sounds
As you can see, the FRS is fairly complex. However, once you understand the information provided in this article, you should be able to use the various tools provided by Microsoft to troubleshoot FRS problems fairly easily.

Transcript from the "Dynamic Route Parameters in Next.js" Lesson
>> Let's head back here. Super awesome, the routing there. If anyone knows a better routing setup in React, let me know. Because, that was pretty easy. Gatsby does something very similar as well. They use the file system. They have a plugin that reads the file system, that plugin is built into Gatsby by default.
[00:00:22] And their syntax is just a little different. I think they use underscores for parameters and not the array brackets, but you get pretty much the same results. So I'm a big fan of Gatsby's routing as well. Cool, we talked about the index stuff there. Let's talk about how do we access the dynamic, the parameters of that route, right?
[00:00:45] So for instance, we have this id here inside this route. This isn't really useful for us, unless we're, I mean why would we make this if we're not going to use the id, right? Like we need this id to do something. So this is, how we interact with that is going to depend on how we render the page.
[00:01:06] But for right now until we get to different rendering modes, we're only really just talking about client side rendering. So everything here is just regular React for now. I'll let you know when we're not doing regular React stuff, but for now, everything's just regular React. So in that case, we can actually use the router lib from Next.js, which I believe is called next/router like that.
[00:01:26] So we can import this. The eslint can't stand double quotes. And I think the one that we want is gonna be called what is it, useRouter? There we go. So useRouter. If you've never used React hooks before, this is a React hook. Most React hooks start with the use word.
[00:01:44] We're not gonna get into React hooks. There's a really good course at Frontend Masters that I wanna say, I think the V5 course actually covers hooks. So, you should check that one out from Brian Holt, that one covers hooks into more detail. I could talk a little bit about if it's confusing to someone, but I'm actually just going to keep moving.
[00:02:03] But basically, we can use this useRouter hook, which is going to give us the actual router. And then we can inspect that router and get the parameters or parameter in this case associated with this page. So what I can do is I can say, gimme the router, which is gonna be useRouter like that.
[00:02:21] And it's also note that if you aren't using functional components, if you don't know the difference between this in React and something like a class component. The difference is, this component is, you can think of it as the whole function is a render function. This is the render function.
[00:02:38] Where as class component, you manually have to create a render function and everything else is not the render function, right? In the functional component, this whole thing is the render function. And that's why hooks are here. Hooks allows us to opt into what we would traditionally have methods, whereas a class component is the other way, you opt into the render function by writing render.
[00:02:57] So just remember that, so that's kind of where hooks are. But the reason I'm saying that is because if you use class components, there's a withRouter higher order component that will wrap your class component that gives you access to the same router object. So they're both the same.
[00:03:11] This is for class components. This is for functional components. So, we're gonna use the functional component, and we're gonna get the router. And then what we wanna do is we wanna grab the id, so we can say id like this is actually gonna be an object, so I'm gonna do structure.
[00:03:25] And that's gonna be from router.query. So router.query is gonna be an object with any associated params on there, and I want the id param. And the reason I know it's id is because that's what I put in the file name. It's whatever I put in the file name.
[00:03:42] If I put, blah, blah, blah, that's what this will be. It'll be blah, blah, blah, right? So I put id, so I'm gonna get back an id here. So what I'm gonna do is I'm gonna return a component like this. And I'm gonna say, notes (Id) like that, right.
[00:04:02] So now, we should be able to see this id inside of our JSX. So let's save that, let's go back to our app. And you can see that is the id that I put here in the URL, right? If I put one, then I'll get one, right. So, pretty useful, pretty easy to get those query params.

Drag multiple Word files to the "Choose Files" section. File extension name can be .doc, .docx, .docm, .dotx, .dotm, .dot, .rtf, .odt, .ott, .fodt, .uot, .eml, etc. Each Word file size can be up to 40 MB.
The batch compression automatically starts when files are uploaded. Please be patient while files are uploading or compressing.
The output files will be listed in the "Output Files" section. To compress all output files in a ZIP file, click "" icon on the right, then click "Add to ZIP". You can right-click on file name and click "Save link as..." to save the file. The output files will be automatically deleted on our server in two hours, so please download them to your computer or save them to online storage services such as Google Drive or Dropbox as soon as possible.
Unblock Files (if needed)
You may need to unblock the Word files if your Microsoft Word software can't open them. To unblock a file on Windows, right-click on the file and open "Properties". Under the General tab, towards the bottom you will see "Unblock" button or checkbox next to "Security: This file came from another computer and might be blocked to help protect this computer". Click on it, then click "Apply/OK".
Office Open XML (also informally known as OOXML or Microsoft Open XML (MOX)) is a zipped, XML-based file format developed by Microsoft for representing spreadsheets, charts, presentations and word processing documents. The format was initially standardized by Ecma, and by the ISO and IEC in later versions.
Binary DOC files often contain more text formatting information (as well as scripts and undo information) than some other document file formats like Rich Text Format and Hypertext Markup Language, but are usually less widely compatible. In Microsoft Word 2007 and later, the binary file format was replaced as the default format by the Office Open XML format, though Microsoft Word can still produce DOC files.
We can't find any open-source projects to compress Word documents, therefore we wrote all the source codes from scratch by ourselves. This Word compressor compresses images in Word document to reduce Word document file size.
Aconvert.com is a sister website of Compresss.com, it focuses on converting files instead of compressing files.

The Marx Brothers' Contract Skit
It's difficult finding a good transcript of this skit. It's one of my all-time Marx Brothers pieces: the contract negotiation skit from A Night at the Opera. So, I've pieced together bits here and put it on my website, mainly so I can point people to it when I think they're being way too picky about things. Some day I'll sit down with the movie and get it word for word. Until then, enjoy!
Groucho Marx: Now pay particular attention to this first clause, because it's most important. There's the party of the first part shall be known in this contract as the party of the first part. How do you like that, that's pretty neat eh?
Chico Marx: No, that's no good.
Groucho Marx: What's the matter with it?
Chico Marx: I don't know, let's hear it again.
Groucho Marx: So the party of the first part shall be known in this contract as the party of the first part.
Chico Marx: Well it sounds a little better this time.
Groucho Marx: Well, it grows on you. Would you like to hear it once more?
Chico Marx: Just the first part.
Groucho Marx: What do you mean, the party of the first part?
Chico Marx: No, the first part of the party, of the first part.
Groucho Marx: All right. It says the first part of the party of the first part shall be known in this contract as the first part of the party of the first part, shall be known in this contract - look, why should we quarrel about a thing like this, we'll take it right out, eh?
Chico Marx: Yes, it's too long anyhow. Now what have we got left?
Groucho Marx: Well I've got about a foot and a half. Now what's the matter?
Chico Marx: I don't like the second party either.
Groucho Marx: Well, you should have come to the first party, we didn't get home till around four in the morning. I was blind for three days.
Chico Marx: Hey look, why can't the first part of the second party be the second part of the first party, then you'll get something.
Groucho Marx: Well look, rather than go through all that again, what do you say?
Chico Marx: Fine.
Groucho Marx: Now I've got something here you're bound to like, you'll be crazy about it.
Chico Marx: No, I don't like it.
Groucho Marx: You don't like what?
Chico Marx: Whatever it is, I don't like it.
Groucho Marx: Well don't let's break up an old friendship over a thing like that. Ready?
Chico Marx: OK. Now the next part I don't think you're going to like.
Groucho Marx: Well your word's good enough for me. Now then, is my word good enough for you?
Chico Marx: I should say not.
Groucho Marx: Well I'll take out two more clauses. Now the party of the eighth part --
Chico Marx: No, that's no good, no.
Groucho Marx: The party of the ninth part --
Chico Marx: No, that's no good too. Hey, how is it my contract is skinnier than yours?
Groucho Marx: Well, I don't know, you must have been out on a tail last night. But anyhow, we're all set now, are we? Now just you put your name right down there, then the deal is legal.
Chico Marx: I forgot to tell you, I can't write.
Groucho Marx: Well that's all right, there's no ink in the pen anyhow. But listen, it's a contract isn't it? We've got a contract, no matter how small it is.
Chico Marx: Oh sure. You bet. Hey wait, wait. What does this say here, this thing here?
Groucho Marx: Oh that? Oh that's the usual clause, that's in every contract. That just says, it says, 'If any of the parties participating in this contract are shown not to be in their right mind, the entire agreement is automatically nullified.'
Chico Marx: Well, I don't know.
Groucho Marx: It's all right, that's in every contract. That's what they call a sanity clause.
Chico Marx: You can't fool me, there ain't no sanity clause.

Add a backslash before some characters
add escape characters to string c#
escape character java
add escape characters to string java
regex escape backslash
add escape characters to string online
Given the string "a|bc\de,fg~h,ijk,lm|no\p" what is the best way to add a '\' before the '|' ',' '~' and '\'
So the end string would be "a\|bc\de\,fg\~h\,ijk\,lm\|no\p"
What is the best way to do this?
I need this in c#.
Thank you in advance.
Can any one help me the the javacsript function that will give me back the original string, take off the extra
Regex would be overkill. Use String.Replace Method (String, String):
string myString = @"a|bc\de,fg~h,ijk,lm|no\p"; myString = myString.Replace("|", "\\|").Replace(",", "\\,").Replace("~", "\\~").Replace("\\", "\\\\");
str1 = str1.Replace("\,", ","); str1 = str1.Replace("\|", ","); str1 = str1.Replace("\\", "\");
How to add a backslash in C++ (\) as a regular text backslash and , Pretty straightforward $ echo '%TY %Tb %Td %TH:%TM %P' | sed 's/%/\\%/g' \%TY \%Tb \%Td \%TH:\%TM \%P. but you can accomplish the Returns a string with backslashes before characters that need to be quoted in database queries etc. These characters are single quote ('), double quote ("), backslash () and NUL (the NULL byte). etrader_x11
If you need to escape only
Regex system characters, you can use the method
Escape like that:
String str1= Regex.Escape("your string with \ - +");
How to match the forward slash using regex, tr can't do multiple characters. Use one of these instead: sed echo "$line" | sed 's/ /\\ /g'. or sed 's/ /\\ /g' <<< "$line". Perl echo "$line" | perl -pe 's/ How can I put a backslash before every space, preferably by using tr or sed commands? Here is my script: #!/bin/bash line="hello bye" echo $line | tr ' ' "\\\ " This is supposed to replace spaces with a backslash followed by a space, but it's only replacing the spaces with a backslash and not backlash+space.
No need to escape all and every character individually, put @ before the string, for example:
string String = @"a|bc\de,fg~h,ijk,lm|no\p";
2.4.1 String literals, This example adds backslashes before quotes and newlines. this example, we have an input string with tabs and after calling add slashes function on this string, we get \t symbols in place of them. Split a string into chunks of certain length. Some characters have one meaning in regular expressions and completely different meanings in other contexts. For example, in regular expressions, the dot (.) is a special character used to match any one character. In written language, the period (.) is used to indicate the end of a sentence.
add backslash before specific character, To use a special character as a regular one, prepend it with a backslash: \. . That's also called “escaping a character”. For example: alert ( "Chapter 5.1" . Some characters cannot be included literally in string constants ("foo") or regexp constants (/foo/). Instead, they should be represented with escape sequences, which are character sequences beginning with a backslash (‘\’). One use of an escape sequence is to include a double-quote character in a string constant.

String literals can contain any character literal. To search for a special character that has a special function in the query syntax, you must escape the special character by adding a backslash before it, for example: To search for the string "where?", escape the question mark as follows: "where\?"

Background / Purpose
Each of you will be responsible to create a data driven question, find the data to answer this question, and build a visual analysis that answers your question with data. A few notes on this project;
- This project is done over a semester. If you try to complete it during the last few weeks of the semester you will not succeed.
- The data science majors will submit this as a part of their degree completion. This project could be a great stepping stone for your senior project.
- I would highly recommend that you do this project well and make it public on your Github repository to demonstrate to employers that you have data programming skills.
The semester project has three different tasks that need to be completed in order to fulfill the task - question generation, data acquisition, and answer development.
Question Generation & Data Acquisition
- [ ] Find 4-5 examples of data-driven answers and write a one-paragraph review of each.
- [ ] List 2-3 items that are unique/good
- [ ] Identify 1 issue with the each example
- [ ] Develop a few novel questions that data can answer
- [ ] Get feedback from 5-10 people on their interest in your questions and summarize this feedback
- [ ] Find other examples of people addressing your question
- [ ] Present your question to a data scientist to get feedback on the quality of the question and if it can be addressed in 2-months.
- [ ] Review the “What do people do with new” data link above and write one quote that resonated with you in your
- [ ] Build an interactive document that has links to sources with a description of the quality of each
- [ ] Find 3-5 potential data sources (that are free) and document some information about the source
- [ ] Build an R script that reads in, formats, and visualizes the data using the principles of exploratory analysis
- [ ] Write a short summary of the read in process and some coding secrets you learned
- [ ] Include 2-3 quick visualizations that you used to check the quality of your data
- [ ] Summarize the limitations of your final compiled data in addressing your original question
- [ ] Finalize first draft of your project analysis
- [ ] Choose your flavor of
.Rmd for your presentation
- [ ] Build a stand-alone analysis that helps a reader answer the question at hand with that available data
- [ ] Present your visualization based analysis that addresses your question
- [ ] Present your analysis to your roommates (or spouse) and update your presentation based on the feedback
- [ ] Get feedback from 2-3 fellow classmates on your presentation and update it based on their feedback

Liferay 6.1.0 CE web-content images not showing after upgrade from Liferay 6.0.6 CE
I have upgraded liferay 6.0.6 to Liferay 6.1.0 for this I already copied the document library folder before upgrade. Now after upgrade all documents are coming fine like word, pdf which is stored in document library folder.
My concern is images which are not displaying correctly. The path of images are like DOMAIN_NAME//image/image_gallery...
To resolve this I have changed the permission to DLHook in Liferay 6.0.6 and then started up-gradation for Liferay 6.1.0 CE. As per my knowledge Liferay 6.1.0 CE only supports DLHook that I have changed already.
Can anyone suggest me what I am missing here?
similar problem is posted on official site : http://www.liferay.com/community/forums/-/message_boards/message/14591675
@PrakashK No luck so far for this issue. In case you have any solution please update me.
Sunil I have upgradated to 6.0.6 from 5.2.3 successfully, all the contents are loading fine, images are fine but the problem is with documents it is not showing. can you please tell me the configuration you have done in 6.0.6 to get them work . Thanks
Hi Mudasar, While upgrading from Liferay 5.2.3 CE to Liferay 6.0.6 CE copy document_library folder and use "image.hook.impl=com.liferay.portal.image.DatabaseHook" and "dl.hook.impl=com.liferay.documentlibrary.util.FileSystemHook"in portal-ext.properties file (according to your system change these properties). HTH Thanks,Sunil
Hi sunil, 6.0.6 is fine but now problem is, when upgrading from liferay 6.0.6 to 6.1 Ga1 , no content , no images and no documents are shown. can you please send me you portal-ext.properties file ? so that I can see what I am missing. Thanks
Hi Mudasar, unfortunately even I am not able to solve the problem. Please share if you get any solution for the same. Thanks, Sunil
Ok sunil I will share , if I get some thing. Thanks
For contents I figured out the problem. do you have problem with contents?
I am only facing problem with images. Let me know if you find something for the same. Thanks,Sunil
I am facing the problem with images, documents and also portlets are removed from the pages :( any idea ?
Parkash or sunil , have you completed migration ? I have some issue

new plugin: user menu with gravatar icon
Requirements:
based on menu plugin
can use gravatar image
can use local image
menu
default entries:
logout
lock screen
default action - dialog to set a command
Sound great, like the one in the Chrome OS bar? You've read my mind :)
a screenie
Required config
plugin {
type = user
config {
border = 2
gravataremail =<EMAIL_ADDRESS> item {
name = Lock Display
icon = gnome-lockscreen
action = slock
}
item {
name = logout
icon = gnome-session-logout
action = xlogout
}
}
}
done, see develop branch
Brilliant work again. I have set it to a static image and it works great
which is enough for me at the moment, but it didn't find my gravatar image
though using:
gravataremail =<EMAIL_ADDRESS>Is there anyway, it could find a Google+ profile image as well?

Hi
You can try this script to fetch gravatar https://gist.github.com/aanatoly/42eac40250baaabd8643
and see where is a problem. Use ``--debug` flag
It works for me with your email both in a panel and with script
Plz post you config, I'll try to reproduce it.
Just in case, fbpanel stores tmp image as /tmp/gravatar so run the script
./wget-gravatar --debug -e<EMAIL_ADDRESS>-o /tmp/gravatar
It correctly downloads the gravatar to /tmp/gravatar but it doesn't set it on the panel. I can manually set the gravatar icon though with:
image = /tmp/gravatar
Here's my config:
Global {
edge = bottom
allign = right
xmargin = 12
ymargin = 5
widthtype = request
width = 14
height = 35
transparent = true
tintcolor = #000000

What does user plugin do? Shows broken image, shows nothing? Can yoiu send a screenshot, plz ? It will help
It comes from your code earlier in this issue when you posted the code needed to implement the gravatar plugin: https://github.com/aanatoly/fbpanel/issues/11#issuecomment-162133768
I can't reproduce it so far.
Let try this:
kill panel
leave in a config file only gravataremail =<EMAIL_ADDRESS>line,
and remove image = .. and icon = ... lines
remove /tmp/gravatar
start panel
and send me a screenshot of what you have now. Thanks
Okay, here's my stripped down config (hope it's what you meant):
Global {

allign = right
xmargin = 12
ymargin = 5
widthtype = request
width = 14

ok, thanks.
Fixed. Now it should work, see develop branch
Thank you, it is fixed :)
Would it be possible to allow customization of the tooltip along the lines
of:
tooltip = $USER is logged in
Also, I don't know whether you would consider allowing for a Google profile
pic as well as Gravatar? I've been looking into it and you can get it by
querying this web address with your Google username:
http://picasaweb.google.com/data/entry/api/user/${GUSERNAME}?alt=json
eg: http://picasaweb.google.com/data/entry/api/user/chromixium?alt=json
Then the website displays the full path to the logo as follows:

Actually, if you decide to implement this, could the icon be downloaded to
~/.face ?
That way it would be set as the login avatar in lightdm...
Don't worry if you don't want to implement this, as I can script it to
create the .face file and run at startup and then just set the image =
parameter in the plugin. It'd just be cool that's all!

Header bidding has been an important inflection point for the programmatic industry. By replacing the traditional waterfall, header bidding has given publishers increased competition, revenue and transparency into their auction dynamics.
In my last post, I discussed how open source header bidding wrapper technology improves efficiency and transparency. Today, I would like to unpack the client-side vs server-side header bidding discussion and how moving to server-side header bidding reduces latency.
Traditionally, latency is caused by a combination of a partner’s network latency with page execution. It can cause ad-call timeouts which in turn will impact demand and auction dynamics. If you want to learn a little more about causes of latency and how to optimize, check out what our architect, Abhinav Sinha, suggests.
Client-Side Header Bidding
Header bidding code, along with ad calls to requisite demand partners, can take place in the header of the page (this method is also known as client-side header bidding). By having multiple header bidders on the page, the publisher can achieve increased revenue. Many publishers manage their multiple header bidding tags within a container called a wrapper tag.
Knowing the right number of partners can be tricky, however. We frequently see publishers get yield improvements as they add up to five or six partners, and then diminishing returns above that number of partners. Publishers need to evaluate the latency versus monetization tradeoffs of adding incremental partners.
Each additional header code within a wrapper increases the page weight as well as adding to the ad calls made to demand partners from the browser. Thus, making the page heavier and causing latency. Connection speeds can impact latency as well. For example, if a user is accessing a page through a mobile device, client-side header bidding can have an even greater impact on page load times.
Latency is problematic because it slows the ad and page load times, which disrupts the user experience, leads to timeouts, reducing fill and ultimately monetization.
Server-Side Header Bidding
To better manage latency, publishers are moving to server-side header bidding and wrappers. Many industry thought leaders consider the move to server-to-server (S2S) the next innovation in header bidding.
Server-side wrappers offer many benefits but one the most impactful is reducing latency. Server-side header bidding can greatly reduce latency because most of the execution is taken off the browser and moved to a server.
Moving the execution to the server makes the page lighter, plus content and ads load faster, resulting in a decreased impact to the user experience. Server-to-server header bidding also allows for a faster response time between DSPs and SSPs.
S2S header bidding is still in its early stages but holds a lot of promise to help publishers achieve increased speed and monetization. For a variety of reasons such as the availability of demand or complexity of managing user syncs across demand partners, some publishers are not ready to move completely to S2S. These publishers can leverage a hybrid solution. A hybrid solution which combines client-side and server-side header bidding, thus improving access to demand and improving monetization.
PubMatic’s OpenWrap solution is a complete hybrid solution which publishers can leverage today. It allows you to maintain your current client-side header bidding demand in addition to managing server-side partners within a single solution.
OpenWrap allows you to leverage all of its UI based tools, controls, and reporting for both your client-side and server-side header bidding partners, as well as bringing you the value of a fully supported enterprise solution with technical support and a dedicated account management team. As publishers deepen their header bidding expertise, the popularity of hybrid solutions offering both client- and server-side integrations, such as OpenWrap, rose from 13.6 percent to 20.7 percent adoption rate between September and December 2017 according to ServerBid.
Learn more about OpenWrap today and let us know how we can partner with you.

Presumed that _all_ packages for _all_ architectures are FHS compliant
at the moment we release 2.2. I fear, that this isn't possible if we
want to release potato in the next half year.
So I still think that we need some interim solution until all packages
are FHS compliant. And we should find this solution before the first
packages using /usr/share/doc are uploaded (I saw a lintian bug
report, where someone noted that his FHS compliant packages didn't
pass the lintian tests, so people already started using /usr/share/doc
and we should find an interim solution soon).

That wasn't my intension. But you should keep in mind, that there are
still packages build in 1997 in slink (uudeview for example). So I
fear that it may take some time to move the complete distribution to
FHS. I fear that it will take at least one year until all packages are
changed and I address this time.
I would prefer a way using postinst or dpkg to provide the symlinks to
be able to remove them at some point in the future without uploading
all packages (with the symlink removed) again.
But at the moment I don't fully know how to do this in detail. We
should find a solution for this (which could be supported by

The Road to Typed Clojure 1.0: Part 1
Ambrose Bonnaire-Sergeant recently released a new blog post about the road to Typed Clojure 1.0. I’m glad work is still happening on it, and the ideas suggested in the blog do seem like they would help a lot with usability, and thus, adoption in real projects.
Has anyone here tried Typed Clojure, especially in a big production scenario? Do you feel the proposed changes would be compelling?
We tried Typed Clojure. A couple of times. We actually went back and forth between Schema and Typed Clojure a few times. We ended up abandoning the use of both (but we have been using clojure.spec fairly heavily since it first appeared).
We ran into a lot of the same problems with Typed Clojure that CircleCI talked about in their post.
When we first tried to introduce it, you couldn’t just annotate one or two functions – you had to annotate everything in a namespace (even if it was just to say “ignore this function”) if you wanted to avoid a giant wall of warning messages. In addition, if you used any third party libraries, it was very difficult to either come up with annotations for those functions or annotate your own code so Typed Clojure wouldn’t complain. Then there were situations where you just couldn’t satisfy Typed Clojure without refactoring your code (quite a few nil-punning idioms tended to defeat both its inference and its conformance).
We probably got about 5% of our code base annotated and checked but it was slow, painful work. We felt the annotations were often detrimental to readability (a complaint often leveled at type systems that don’t do enough inference). We also found that sometimes you’d refactor or enhance some code and the annotation would be outdated and then you’d have to wrestle that back into compliance (sometimes leading to more refactoring just to satisfy Typed Clojure).
If Ambrose can make it do more inference – and better support nil-punning idioms – as well as better handling the boundary between typed code and untyped code (there was a great talk about this specific issue in the context of Typed Racket at one of the Clojure conferences, as I recall?), then Typed Clojure might be more tenable.
I think gradual typing is a promising approach to adding more checking to Clojure code. I think some of Clojure’s idioms make type inference an extremely hard problem to solve.
Given that we now have clojure.spec, I don’t think that I would invest my time in trying to introduce Typed Clojure into our current code base at work. I’ll definitely keep an eye on the project, as it moves forward, tho’…

I’m able to decrypt it with the
--header parameter but when I try to mount it I get the following error:
# mount /dev/mapper/luks /mnt
mount: /mnt: unknown filesystem type 'LVM2_member'.
I was instead able to mount the LV:
mount /dev/qubes_dom0/root /mnt
There was indeed a
/boot folder with the following structure:
#ls -a /mnt/boot/
. .. efi xen-4.14.4.config xen-4.14.4.gz
I removed it, rebooted but the issue persisted.
Qubes still does NOT boot
Ah yes my bad, this right.
After decrypting /boot, you should be showed a grub menu, press ‘e’ then check how it would boot, or you can take a image and post it here.
About that… During the installation of Qubes, when chrooted I set the following params in order to speed up and already excruciating slow boot:
So now pressing
e does nothing.
However I decrypted the detached boot partition and checked
/boot/grub2/ and to my surprise I did not find
Should I decrypt everything on live, mount
/dev/qubes_dom0/root and generate a new grub.cfg while chrooted? If so, could you indicate me the best way?
Your boot config is in EFI partition (/boot/efi/EFI/qubes/grub.cfg), not in /boot/grub2,
So after you decrypt your /boot and mount it to /mnt, you should mount your efi to /mnt/efi.
I’ve did this once and resolving this wouldn’t be that hard.
Can you confirm /boot folder in /qubes_dom0/root already removed ?
Try boot again and if you still entering dracut emergency, please provide
/run/initramfs/rdsosreport.txt it actually tell us how it boot so it could give a hint of what happen.
No, remember we are doing detached boot, so It’s should be nothing in /boot folder.
Everything is done in your flashdrive.
Yes, I removed it already
What I meant was mounting
/mnt then mounting
/dev/mapper/luksboot (from the decrypted boot partition of the flashdrive) to
mount -o rw /dev/mapper/luksboot /mnt/boot.
But as I now found
grub.cfg in the efi partition this should no longer be necessary.
I’ll do it now and report back
Here’s the final portion when it started showing errors:
The original is very long, let me know if it’s needed (if that’s the case, I’d rather send it privately as it contains more identifiers).
I didn’t bring my laptop today, so i’m not sure how it would resolve for your case.
I’ll publish my notes tomorrow.
I think there’s a problem in your sd card based on the image you share, I’ve confirm that upgrading kernel with or without detached drive will not affect anything, except that you already installed kernel.
Can you share the full log on the dracut emergency ?
Wait what exactly made you think that, because this was the right call. I restored a backup I had made of the sd card and just like that the system booted up correctly.
Seriously, thanks a lot for the help and the time you dedicated me.
But now I wonder, what’s the right way to update grub and initramfs with a detached boot?
Because everything is boot as normal, first boot it called your efi configuration, second it asking you to decrypt the password (in that case, its absolutely your configuration), then in the log i’ve seen that it was looking for /dev/mmcblk.
Try using good quality of sd card, as far i know, 4 - 8 gb using low grade chip.
and for your backup, it’s okay to have a backup in the /dev/qubes_dom0/root, no need to add additional drive.
There’s no easy way, just make sure sys-usb is not automatically started when you want to upgrade kernel.
What I meant is, since a
/boot exists when the system is on, would I need to delete it, mount the sd card on
/boot and then update grub/initramfs? Or is there another procedure?
if your detached boot drive never been unmounted, then just do as normal, and you don’t need to update grub / initramfs, it would be done automatically.
I’ve re read your situation in the #1 perhaps you using sys-usb ? remember that when you using sys-usb, it’s passing the usb controller to sys-usb and that would umount your detached boot drive. That’s why i said you need to turn off auto start sys-usb when you want to upgrade kernel.
And for your situation now if you want to upgrade kernel,
- boot as normal.
- umount your detached boot.
- make sure it already removed.
- uninstall recently installed kernel, then remove everything on the /boot
rm -rf /boot/*
- turn off auto start sys-usb then reboot.
- boot as normal, install new kernel then turn on auto start sys-usb and reboot (or you can reboot first to use newer kernel, remove old kernel, then turn on auto start sys-usb and reboot).
I really keep it clean, so i always switch to new kernel then remove old kernel.
I do use sys-usb but the sdcard controller is not attached to it, it’s attached to dom0. I’ve been highly reluctant to attach it to sys-usb as I’m afraid it’ll make my system unbootable, since I have to decrypt the root partition with the sd card.
And thank you lots for the step-by-step
I have a correctly working Qubes installation based on the detached headers tutorial (UEFI). Everything is working fine.
However, I have had problems in two situations:
- When using a sys-usb, the system won’t boot correctly.
- In addition to sys-usb, using
rd.qubes.hide_all_usb in my grub configuration will have the same effect. Does not boot.
Sorry for not putting up more details on the failures ( can’t remember in which case I’m landing on dracut shell, and in which one I just get straight to boot). Quite reluctant to retry without some advices first.
So a couple questions, hopefully the good ones:
- Is it possible at all to use
rd.qubes.hide_all_usb in this setup ? Would be great since there is quite no point to use sys-usb otherwise.
- About the need to turn-off sys-usb autostart before upgrading, has someone found a better/automated solution ? One again, being quite busy/lazy I have not tried to write any such script.
Wondering if anyone has had the same problems.
Also, my efi/boot/headers are on a USB drive, in case it makes any difference, but I can’t see which one…
Grateful for any support, and thanks a lot for these great tutorials !
It would be great for @51lieal to support this thread.
well its already solved, you can try create new thread and explain your problem.
I apologise. I posted on the wrong thread.
Here is the correct post.

Google Sync Devices
- Android Os 2.2+.
- In the event that you receive the message "Your domain calls for smart phone administration. Kindly install the Google Apps Device Policy application to enforce protection policies" in your Android os device, you'll want to put in the Google Apps Device Policy app.
Some organizations need their users to put in the Google Apps Device Policy software on their device. Failure to install the software may stop your mail, diary, and associates from syncing along with your device. Speak to your G Suite administrator to get more details.
Your administrator can set here protection policies:
- Unit code power.
- Device code size.
- Quantity of invalid passwords permitted before the device is wiped.
- Quantity of recently expired passwords being obstructed.
- Range days before a device password expires.
- Amount of idle minutes before a tool immediately locks.
- Application auditing.
- Remote account elimination from a tool.
- Remote wipe a computer device.
- Unit policy app variation demands.
- Quantity of times device isn't synced before cleaning.
- Blocking of security-compromised products.
Your administrator can also configure Wi-Fi networks and control community accessibility certificates with the software. They could choose to conceal a network's details to make certain that only people that have the system name and password can hook up to it.Just what people can do with all the Google Apps Device Policy app
Whenever you start the product policy application on your own unit, it opens up on Status display screen. To view the guidelines or emails display screen, swipe from the remaining to pick the display screen you want to see. You can use these devices policy application to:
- Control your device: you have access to the My Devices page to ring, secure, and locate your product including reset your screen-lock PIN. You may remotely wipe your device in case your administrator features enabled remote wipe for users.
Note: Your location information is not shared with your administrator.
- Sync your device: From the reputation display screen, you can see if your product last effectively synced using the host. To manually sync your device to make sure that you've got the many current guidelines, you touch Sync Now.
- View protection policies and system options: on guidelines display screen, you will see the security guidelines that your administrator set in your unit. If for example the product does not conform to any of the ready policies, you'll want to take action to eliminate all of them. You will see the list of facts about your product which can be distributed to your administrator, such product policy application version, unit OS variation, device design, your email address, etc. You are able to see the Wi-Fi companies that your particular administrator configured and server certificates.
- Get multiple-account support: If you establish the product policy software with numerous G Suite accounts with different guidelines, the essential restrictive plan is implemented on your own product. If one domain needs these devices PIN to be 4 characters lengthy and another needs that it is 6 characters very long, these devices enforces the 6-character size. To find out more, G Suite directors can easily see handle Android devices.
- Create a work profile: Should your company is signed up for Android os for Work, you can establish a-work profile when you have an Android os 5.0+ device that supports handled pages. Android for Work enables you to effortlessly switch between work and personal apps on your own device.

Microsoft's Office and the Windows operating system have always led the top downloads of software piracy platforms. The company has already tried to get a grip on them with various (often customer-unfriendly) measures.
A research document has published a completely transparent incentive system for anti-piracy campaigns. The document contains an examination of a transparent blockchain-based system by Redmond software giant, with the participation of experts from Alibaba and Carnegie Mellon University. Argus is based on the Ethereum blockchain, and aims to create a trustworthy incentive mechanism while protecting the data of anonymous reporters.
Given that piracy is essentially about distributing copyrighted content outside of legal distribution channels, the key question in combating piracy is how to incentivize people to report pirated content. Industry associations and companies have offered large rewards for reporting pirated content. For example, the Business Software Alliance (BSA), whose members include Apple, IBM, Microsoft, Symantec and many others, has offered a $1 million reward for reports.
Argus, with the help of a digital watermark, is designed to make it possible to trace pirated content back to its source. The four pillars of the Argus concept are total transparency, incentives, information hiding and optimization. These are the main focus areas that are discussed in more detail in this paper. It is worth noting that these are not four problems to be solved individually, but integral aspects in a coherent design.
Argus allows pirated content to be traced back to the source with an appropriate watermarking algorithm, which is described in detail in the paper. With the "Proof of Leakage", a procedure to hide information is performed every time leaked content is reported. In this way, no one but the whistle-blower can report the same watermarked copy without actually possessing it.
The researchers have optimized several cryptographic operations to reduce the cost of a piracy report to sending about 14 ETH transfer transactions. This would otherwise be equivalent to thousands of transactions on the public Ethereum network. With the security and practicality of Argus, Microsoft hopes that by moving to a fully transparent incentive mechanism, anti-piracy campaigns will be truly effective in the real world.
A fundamental challenge is the interest of whistle-blowers (customers) to remain anonymous to the public. The interest of the owner (Microsoft) is to collect bona fide reports so that the severity of the infringement can be accurately assessed. However, the interest of each whistle-blower is to maximize his or her own reward. In Argus, the incentive model ensures that the total reward of the informant and all of his sybils is less than the reward he would receive without falsifying the sybils. In other words, the model discourages Sybil attacks so that the informant's interests are aligned with those of the owner. In addition, the model is superior to previous models for better incentives due to several other features.
Because Argus runs on a public ledger, its execution is completely transparent to everyone. It is critical that a whistle-blower not be able to resubmit a report that was previously submitted by someone else. For this reason, the Argus protocol for submitting reports is based on the Multi-period Commitment Scheme, which provides a "zero-knowledge" guarantee, meaning that a submission only proves that the whistle-blower has a copy of the content without revealing any other information. Compared to traditional commitment schemes, this scheme does not reveal useful information even in the disclosure phase, while avoiding the high cost of zero-knowledge proof.
Microsoft's anti-piracy efforts are fundamentally a process based on collecting data from the open, anonymous population, so the question of how to incentivize credible reporting is at the heart of the problem. Academic researchers and real-world companies have developed various incentive mechanisms. However, because the interests of the various roles and the goals of an anti-piracy system are not explicitly defined, developing such a mechanism is more of a "creative art" than a systematic and disciplined investigation.
The researchers see the most important value of this work not in the Argus system itself, but in the approach that led to its design and implementation. First, the interests of the various roles and the goal of full transparency are established without trusting any one role. Once these were established, all the design requirements emerged on their own, such as Sybil security, information transfer, resistance to infringement denial, etc. Once these design requirements were clear, they were able to derive the general form of valid solutions rather than inventing them; the derived general form then boils down to a series of unavoidable technical obstacles, which can be overcome by adapting cryptographic techniques, writing contract code, and optimizing performance.
Argus is an example of the result of a disciplined approach. It is superior to existing solutions in terms of trust acceptance and assured properties. It is a compelling use case for public blockchains because:
- It is feasible to develop a fully transparent solution without introducing a trusted role. This could enable a paradigm shift in anti-piracy incentive solutions.
- Such a solution actually consolidates the interests of all roles in a fair way, i.e., as long as one role is not guilty, its interests are not affected by other malicious or guilty roles;
- In addition to being logically sound, the solution is also economically feasible due to the effective optimizations.

java.lang.ClassCastException: ListActivity cannot be cast to DatePickerDialog
I'm having problems to implement this Material DatePicker due to the Context call that I should probably be doing wrong.
The sample from GitHub works just fine because the Dialog is being created by an Activity.
However, at this particular case, I'm working with a Fragment attached to a ListActivity.
This is how I'm calling it:
Calendar now = Calendar.getInstance();
DatePickerDialog dpd = DatePickerDialog.newInstance(
(DatePickerDialog.OnDateSetListener) getActivity(),
now.get(Calendar.YEAR),
now.get(Calendar.MONTH),
now.get(Calendar.DAY_OF_MONTH)
);
dpd.show(getFragmentManager(), "Datepickerdialog");
This line (DatePickerDialog.OnDateSetListener) getActivity() is generating the issue. It is declared as MainActivity.this in the sample, but I can't use ListActivity.this or something similar.

@AnirudhSharma it's not possible to make this call at all
Yes i'm aware of it, but I'm not familiar with the correct call for this interface. oh come one ... solution is simple: you should implement DatePickerDialog.OnDateSetListener in ParameterListActivity or pass there different instance of this interface implementation (which ParameterListActivity is not)
@Selvin this is already implemented a long way ago.
no, it is not ... you would not get this exception ... try to check your imports ... maybe you are implementing wrong interface (same name - different package)
Sir, it was implemented. I would never do that kind of mistake. Therefore, as you mentioned, it was wrongly associated by Android Studio auto imports. I appreciate your help.
Do not trust evil auto imports :) .... also do not call me "sir" :)
@Machado you call getActivity() in your code. So this code from fragment. What implement DatePickerDialog.OnDateSetListener: activity or fragment?
@Machado Attach your ParameterListActivity code.
Silly mistake.
As previously mentioned by @Selvin in the comments, the interface call was implemented, therefore, it was wrongly associated by Android Studio auto imports.
TIP: Do not trust evil auto imports. :)
Your activity should implement DatePickerDialog.OnDateSetListener for handling callback void onDateSet(DatePickerDialog dialog, int year, int monthOfYear, int dayOfMonth); from DatePicker.
Or you can handle it using anonim class:
DatePickerDialog dialog = DatePickerDialog.newInstance(new DatePickerDialog.OnDateSetListener() {
@Override
void onDateSet(DatePickerDialog dialog, int year, int monthOfYear, int dayOfMonth) {
//Your code.
}
}, year, monthOfYear, dayOfMonth);

Does the business logic for deserializing a JsonPayload have to match?
I am currently attempting to deserialize a Json Payload that has been fired from a webhook URL on an MVC application, but I do not know if the business logic provided has to match exactly to prevent any null values.
Basically the Json Payload contains way to much useless information that I do not what to display. This is a brief preview of what the Payload looks like:
"webhookEvent":"jira:issue_updated",
"user":{
"self":"http://gtlserver1:8080/rest/api/2/user?username=codonoghue",
"name":"codonoghue",
"issue":{
"id":"41948",
"self":"http://gtlserver1:8080/rest/api/2/issue/41948",
"key":"OP-155",
"fields":{
"summary":"Test cc recipient",
"progress":{
"progress":0,
"total":0}, ....
I only want to display information about the issue and the other information is just white noise to me and don't want to use it. Now do I have to create classes only for the issue details etc like this:
Public Class jiraIssue
Public Property id As String
Public Property key As String
Public Property fields As jiraFields
End Class
Or do I have to make sure to provide sufficient business logic about the User class just to make sure that it will be received correctly? I also know that using Json2csharp.com the classes that can be made are user, issue, fields, progress as well as the overall RootObject, so I also want to know is do these classes need to contain the exact same matching variables as the JsonPayload, e.g. I don't want progress to have the variable total.
When using Json2csharp that in every class they contain an ID variable with the property as string and I would like to know if this is needed in the classes to be able to display the information or can I not use it as it is also irrelevant.
The main thing that I want to deserialize is the RootObject, which contains a webhookEvent (string) an issue (which links to issue class, which links to fields class which links to all relevant information), comment which links to a comment class. I want to deserialize this so would this be correct?
Public Class Rootobject
Public Property webhookEvent As String
Public Property issue As Issue
Public Property comment As Comment2
Public Property timestamp As Long
End Class
Public Class Issue
Public Property key As String
Public Property fields As Fields
End Class
Public Class Fields
Public Property issueType as IssueType
Public Property summary As String
Public Property summary As String
End Class
Dim Issue As RootObject = New System.Web.Script.Serialization.JavaScriptSerializer().Deserialize(Of RootObject)(json)
For Each item As var In Issue.issue
Console.WriteLine("WebhookEvent: {0}, issue: {1}", item.WebhookEvent, item.issue)
Next
Update
It seems that the problems that I was having was due to the JsonPayload itself, the business logic did not affect. There were issues with the incompatible characters, some fields were null and could not be and a few others as well.
Why do you use JSONP term? How this applies to JIRA web hooks?
@AleksandrIvanov So far I have created an application that sends an email to JIRA to submit an issue once this is done the webhook will fire to my application a JSON payload which is currently in requestb.in which is were I am getting this information, I need to use the correct business logic so that l can consume this correctly and display certain pieces of the information but not everything
It's normal to have only data that you need in your models.
I need to data from the JsonPayload I just created the model classes so that I could display the information sent from the Payload
What do you mean by Payload?
the Json Payload is just the Json sent by the webhook {"webhookEvent":"jira:issue_updated","user":} etc I am trying to deserialize it
I have correctly got my Json payload correctly read in and the Json Payload information does not have to correctly match up with the classes that you create. You only have to create classes and variables for the information that you need from the Json Payload. For example if you did not want the information on comments do not create a comment class.
Public Class Rootobject
Public Property webhookEvent As String
Public Property issue As Issue
' Public Property comment As Comment2
' comment out the comment class because it is not needed
Public Property timestamp As Long
End Class

Adds video upload
This squashes the changes in #929 down to a single commit, incorporating comments from @Harmon758.
Some of this work is due @jamesandres and @Choko256.
This is currently in draft because I have poor internet for the next week and testing video upload isn't feasible. We've waited five years, so another week should be fine. 😄
I think it would be preferable to keep the original commits if possible, to keep credit where it's due.
How about I squash them all into a single commit with multiple authors?
Is there a reason it needs to be a single commit?
Yes. The main branch has changed so much since this was introduced that rebasing each commit is tiresome.
Wouldn't it be possible to use the original commits already in your video-upload2 branch and make a merge commit that merges the main branch and resolves any conflicts? I think if you really wanted to, you could even just copy all the code as it is in this commit and paste it as part of the merge commit. Although, it'd be preferable for the additional changes in this commit to be separate from changes for conflict resolution as well. Another reason for this is that it'd be easier to specifically review the changes you made in addition to what's already in #929 and the additional commits you have in video-upload2 than to re-review the entire thing.
Thank you @Harmon758 and @Maradonna90 for your help reviewing. I've incorporated your suggested changes.
In particular:
new global constants are used for tracking the MIN, MAX and DEFAULT chunk sizes. All of these constants are stored in KiB, and multiplied by 1024 when comparing to bytes.
Enhancement: the api.media_upload method will use chunked upload for images that exceed the standard upload size limit
Repeated logic around checking file types has been removed/simplified
I added two test files (gif and mp4) and three methods (and casettes) around the media upload endpoint.
I am eager for the video upload feature, and respectfully ask that it be added to tweepy as soon as possible. Thank you all for your work on this project.
If I upload a bigger video and try to post a tweet with it I can get a 324 errorcode with not valid video. This happends because the upload hasn't finished yet.
I checked the twitter API and found a method that checks for the upload progress of media. I wrote a small function in my project to use it.
def get_media_upload_status(api, *args, **kwargs):
""" :reference: https://developer.twitter.com/en/docs/twitter-api/v1/media/upload-media/api-reference/get-media-upload-status
:allowed_param:
"""
return bind_api(
api=api,
path='/media/upload.json',
payload_type='media',
allowed_param=['command', 'media_id'],
upload_api=True,
require_auth=True
)(*args, **kwargs)
potentially the media_upload method should return the media_id when the media_upload finished. The above funciton could be used within a routine.
I'm new to using github. How do I use this video upload version as my tweepy for python? What's the pip command for this specific version to install it? Sorry I'm a newbie
I'm new to using github. How do I use this video upload version as my tweepy for python? What's the pip command for this specific version to install it? Sorry I'm a newbie
I'm also a newbie, but this is what I just did to get it installed:
git clone https://github.com/fitnr/tweepy.git
cd tweepy/
git checkout video-upload-3
pip3 uninstall tweepy (if you have an old version installed. We're going to replace it)
python3 setup.py build
sudo python3 setup.py install
I'm gotten it installed, and have successfully to use it to post the included example video.mp4. When I try to post one of my videos, it is successfully assigned a media_ID, but then with the api.update_status command, I get tweepy.error.TweepError: [{'code': 324, 'message': 'Not valid video'}]
This same video works fine if I upload it by hand in the Twitter web interface. It's a little 17KB MP4, definitely not too big.
I don't know if this is a bug tweepy code or if twitter is just being weird about my MP4s.

have you tried it with time.sleep(10) between the media_upload call and the api.update_status ?
have you tried it with time.sleep(10) between the media_upload call and the api.update_status ?
Thanks for the suggestion. I've tried this now. Same thing.
I found the solution to my Not Valid Video problem. Seems twitter is very fussy about the video codec.
The ffmpeg command shown here converted my video to a format twitter is happy with
https://gist.github.com/nikhan/26ddd9c4e99bbf209dd7#gistcomment-3232972
and tweepy uploaded it with no complaint!
-K
I've added a commit with @Maradonna90's get_media_upload_status, it's much more efficient than time.sleep(10)
@Harmon758 @Maradonna90 bump
I've gone ahead and made a branch, https://github.com/tweepy/tweepy/tree/video-upload, and merged this into it.
I've also drafted PR #1486 merging it into the master branch.
I'll be making further improvements in that branch and PR, but as I said before, feel free to PR to that branch if anyone else wants to make additional improvements as well.
@vegit0 @savetz See https://tweepy.readthedocs.io/en/latest/install.html and https://pip.pypa.io/en/stable/reference/pip_install/#git.
The [{'code': 324, 'message': 'Not valid video'}] error keeps happening
Shouldn't media_upload wait for it before returning?

Are you using the video-upload branch / PR #1486? This PR has been superseded by that one.
Regardless, videos need to meet certain specifications for Twitter's API.

Wait for what?
I'm using the "video-upload" branch.
Ok let me explain.
When I'm calling
uploaded_media = api.media_upload(output_filename, media_category='TWEET_VIDEO')
I expect the function to return when the state of the upload is no longer "pending".
Instead I think it's returning right after the "finalize" call. However, after calling finalize you still have to wait until Twitter has ended processing the video, as explained in the docs:
it may also be necessary to use a STATUS command and wait for it to return success before proceeding to Tweet creation.
I feel that the same way the API is handling all the process from start to finalize, it should also wait for STATUS not to be "pending" instead of having to handle that outside this library.
I have currently fixed it on my own code using a while loop and waiting for the proper state like this:
uploaded_media = api.media_upload(output_filename, media_category='TWEET_VIDEO')
while (uploaded_media.processing_info['state'] == 'pending'):
time.sleep(uploaded_media.processing_info['check_after_secs'])
uploaded_media = api.get_media_upload_status(uploaded_media.media_id_string)
api.update_status('@' + tweet.author.screen_name + ' ', in_reply_to_status_id=tweet.id_str, media_ids=[uploaded_media.media_id_string])
I hope it's clear now.
Thanks

Ah, I see. Thanks for the feedback.
I think I'll probably add a kwarg to allow waiting for the async finalize process to finish.
I'll look into it later and let you know in #1486.

First things first. My CI server is a VM running CruiseControl.NET. I dont use Jenkins so I cant really comment on it. From the looks of things, Jenkins is more well-developed than CC.NET.
Per the virtual vs physical question: ultimately, it doesnt really matters as far as CI is concerned. As long as it is visible on the network and has enough resources to perform it's function, the rest is just administration. Personally, I find benefits of virtualization to be worth the extra effort. You can easily add resources, move its physical location, stand up additional VMs to run a cluster. The benefits of virtualization are well known and everybody is doing it these days.
My CI server is on a VMWare ESX server that has a ton of CPU and RAM to dish out. It runs many other VMs on it. I have about 35 sites running through CI and probably 20 are hosted on the machine itself and another 70 sites that are set to build by manually triggering them through the CI dashboard. I have never had any relevant performance issues with it.
Your build server should ideally have the same setup as whatever machine(s) you are planning on deploying your code to. For websites, that would be the same OS as your production servers (probably Windows 2003 or 2008). For desktop applications, I would probably just pick the latest and greatest OS that you are targeting for support and can afford.
Using multiple machines with multiple OSes would only be relevant when you are building desktop applications that you are trying to support on multiple OSes. In this case, having multiple servers would be ideal, but I see that as being a lot of work to get set up. Personally, I would start simple, get everything running and start adding pieces on when they become truly necessary.
As I mentioned, I use CruiseControl.NET. It's been great so far and I am happy with it. Since it is written in .NET and you are using .NET, there are less moving parts that your server needs to get running (I see Jenkins is built on Java). Writing plugins/extensions would be theoretically easier since you already have .NET people in house. I've never written an extension for CC.NET so I cant say that with certainty, though I know it is possible. The down side is the community is small and active development is slow.
Finally, I'll add that it will be A LOT of work to get started. It took me over 6 months to get my CI server ready for production, a few more to migrate all of our projects over to run through it and many more to train the rest of the developers on how to use it or work with it.
So, in summation,
- Virtualization is good! (but it doesnt really matter).
- You should match you CI environment to whatever envirnoment you are deploying to, if possible.
- You better be ready to commit for the long haul.
- Continuous integration is great and you wont regret setting up a CI server. Whatever you choose, it will be better than the "cowboy coding" that used to go on :)
EDIT Other answers are posting their process, so I guess I should have done that too! :)
My shop builds LAMP and .NET websites so we needed something that could work effectively with both. We have CC.NET running as the core framework but nearly all of the functionality is performed by custom Nant scripts. We use Nant because it is 1) .NET based and has built in .NET commands and 2) is easy to perform command line operations which form the core of all of our build steps.
CC.NET listens to the SVN server and grabs updates as they are made. CC.NET checks them out and fires off the NANT task that performs all the actual work. For .NET, that means mstest to unit test and msbuild to build and publish. PHP usually just moves the files straight to the destination environment. Then, if all steps were successful, Robocopy will copy the files to the destination server, which was mapped as a network drive during a Group Policy startup script (Windows servers are mapped with net use and LAMP servers are mapped with Webdrive).
We have development servers, staging/QA servers and production servers. Since we work in .NET and LAMP, we have one server per environment for each of these stages - 6 in total and all are virtual. Our development servers are the only ones that are set to a continuous integration build. Staging and production are force-build only along with some other SVN wizardry to prevent accidental deployments. We also build and unit test AcrionScript using MXMLC but that is rare for us.

JQuery Add/Remove Attribute On Input Field IE
I'm using some simple jquery to add helper information to an input field when a user clicks into it.
$('.amount').focus(function(){
$(this).attr('placeholder', '$0.00');
});
$('.amount').focusout(function(){
$(this).removeAttr('placeholder');
});
<div class="input-field">
<input id="amount" class="amount" name="amount" type="text" maxlength="15" class="validate" />
<label for="amount">Deposit Amount</label>
</div>
https://jsfiddle.net/f9mvyz5f/1/
When the user enters the Deposit Amount Field, the placeholder $0.00 becomes visible - or at least it does in Chrome, Firefox and Edge. However this does not work in IE11. Is this another one of those attributes that IE11 doesn't support?
take a look here : https://stackoverflow.com/a/7225820/5644965
You don't need javascript to add usefull information to an input. Just by adding the placeholder="$0.00" attribute to the input will be enough.
<div class="input-field">
<input id="amount" class="amount" name="amount" type="text" maxlength="15" class="validate" placeholder="$0.00" />
<label for="amount">Deposit Amount</label>
</div>
The problem is that Internet Explorer 11 uses the placeholders in a slightly different way. The placeholder text is displayed when the user does not have focus on the input, but as soon as the input gain focus, the placeholder is hidden. So on Internet Explorer 11, there is no such behavior as in the other browsers (keeping the placeholder text until the user writes something in).
There are several polyfills to add the placeholder behavior to old browsers, but those polyfills will only work if the browser does not support the placeholder attribute, and Internet Explorer 11 does support the attribute.
Edit i added this solution, to maintain the same experience cross browser.
https://jsfiddle.net/f9mvyz5f/3/
I should clarify that I am using the materializecss framework. The snippet above is not styled with the library. I've updated my fiddle to better reflect the full user experience.
Adding the placeholder attribute thru JavaScript won’t change much on IE11. On focus you are adding the placeholder to the field, but if the field has a placeholder attribute IE11 will hide it on focus. So you will never be able to see the placeholder itself. Will you be ok showing the placeholder always o you want to show it only when the user focus the field?
The requirement is for when the user clicks in the field, like the example here at https://jsfiddle.net/f9mvyz5f/1/. I get the distinct feeling that this is another "IE just doesn't do this" item, because it seems to work in every other major browser.
In fact IE11 does not do the placeholder stuff that way. We can create some sort of workaround.
@RPM check my edit; i added a link to jsfiddle where i manage to achive the same placeholder behavior cross browser (including IE 11).
this is a great solution. I've tested cross browser and it's exactly what the doctor ordered.
@RPM glad i could help you! :)

Revision as of 14:11, 4 December 2019
Welcome to Cyberhunt, the privacy capture the flag competition!
- 1 Overview
- 2 Challenge 1: Link Shim Attack
- 3 Challenge 2: Linkage Attack
In a generation where technology is essential to our daily living, do we really think about how secure our assets are? Our project provides a unique approach to cyber security and privacy. Instead of a typical approach of feeding mass amounts of information to users, our project allows users to be more immersed in the world of cyber security and privacy. Our simulations will give the user an offensive/ hacker-like approach which in-turn will educate them on effective defensive cyber security techniques. In order to beat the hacker, you have to think like a hacker.
Our goal is to educate and raise awareness on the importance of Cyber Security. Technology in the information age is a double edged sword. The more we immerse ourselves in technology, the more people will exploit technology for their own personal agenda. We aim to mitigate this exploitation of technology by educating people on how to defend their information against cyber-attacks
Challenge 1: Link Shim Attack
Congratulations! You just became a victim of a link shimming attack.
- What is a link shim attack?
- It is 'the practice of obfuscating URLs in emails for tracking purposes, to track which links you click on. Link shimming, and link tracking more generally, is commonly used on the web by search engines and social media companies.' Attackers can also use it to take information that was not approved by the victim.
- How it works?
- How to prevent it?
- Before you click a link in an email, you can hover over the link to see that it is different from the text. Copy and paste the link into your address bar to make sure that you are going to the right address.
Challenge 2: Linkage Attack
What is a Linkage Attack?
- A linkage attack is a method cyber criminals use to identify individuals using a data set by combining information from one data set with another. These cyber criminals use pieces of information named Quasi-identifiers. Quasi-identifiers are pieces of information that are not meaningful alone. However, when they are combined with other Quasi-identifiers they can create a picture that can identify an individual.Examples of Quasi-identifiers are, postal code, date of birth, salary, transaction history, etc.
- Alone each of these Quasi-identifiers is not specific enough to identify an individual. However, when combined the likelihood of identifying an individual is much higher. Linkage attacks are one of the most commonly used cyber-attacks because seemingly non harmful data is often enough to identify an individual.
- In our challenge the user will be simulating a linkage attack by collecting information on individuals based off of data provided on social media platforms (Instagram, Snapchat)
- The Boyfriend, ((Will), which is who you are in this simulation), believes his Girlfriend has been acting weird lately. His suspicions lead him to believe his girlfriend has been cheating on him. So he decides to conduct a linkage attack using snapchat and Instagram as sources. You are the boyfriend. Use the information provided in snapchat and Instagram to find out who your girlfriend is cheating on you with (Stacey is your GF). You will use snapchat to narrow down your suspects. Then you will use Instagram to find a relationship between Stacy (the girlfriend), suspect friends, and a suspect finsta profile. With this information you will be able to decipher the owner of the finsta profile. Which will link you to the person your girlfriend is cheating on you with.
- The user will use the data sets provided to conduct a linkage attack to figure out who his girlfriend is cheating on him with.
Snapchat Emoji key
Instagram Data Table
- Examine the emojis on the snapchat screenshot and the names associated with them. The smiling face means that the snapchat profile are best friends. The grimacing face means that your profile and that snapchat profile have the same #1 best friend.
- Go to instagram and look at the people that Tony and Mike follow.
- Look for the finsta account that only Tony, Mike, Stacy, and Tina follow and try to follow it.
- Look through Mike and Tony’s pictures and find what the finsta accounts likes.
- Notice that Stacy likes the same pictures
- Fill out the table to help you understand and follow along easier.
- When you fill out the table, you will be able to make a confident conclusion on who the finsta belongs to.

The URL in Python Selenium is opened or fetched using the driver.get() method of the selenium module.
is a function used to delay the execution of code for the number of seconds given as input to time.sleep(). The time.sleep() command is used to sleep the window. You can use the time.sleep() function to temporarily halt the execution of your code. For illustration, you are staying for a process to complete or a file upload.
you’ll need the locators from it if you want to perform any automated action on a web page. These are unique identifiers associated with the web elements such as text, buttons, tables, div, etc.
It is not possible to interact with the web page if the test script is not able to find the web elements. Selenium Webdriver provides the following ways for detecting web elements.
- Detect Element by Name
- Detect Element by ID
- Detect Element by Link Text
- Detect Element by Partial Link Text
- Detect Element by XPath
- Detect Element by CSS Selector
- Detect Element by Tag name
- Detect Element by Class name
Click On Web Elements
We can click a button( elements) with Selenium web driver in Python using the click method ( .click() ). First, we have to identify the button to be clicked with the help of any locators like id, name, class, xpath, tagname, or CSS as per mention as per mentioned above. Then we have to apply the click method ( .click() ) on it. A button in HTML code is represented by a button tagname.
Sendkeys in Selenium
send_keys() is a method in Selenium that allows the Tester to type content automatically into an editable field while performing any tests for forms. For example, to test a login page, the username and password fields require some data to be entered. The tester uses the send_keys() method to enter the field values.
Submitting a form in Selenium
There are many techniques for submitting a form in Selenium. One of the methods is to directly use the click() method on the form submitting button. The next method is to use the submit() method on the form page.
In the below e.g you can get an idea that how to do automation testing in selenium with the python commands
driver = webdriver.Chrome(WEB_DRIVER_PATH)
username = driver.find_element(By.ID, "id_login")
password = driver.find_element(By.ID, "id_password")
loginForm = driver.find_element(By.ID, "signin_form")
invalidLogin = invalidLogin()

I need a HIGHLY skilled and artistic designer--not a front-end coder! You must be ARTISTIC, have a great eye for design, and be creative. My site will have a similar look/feel to the sites below.
- clickable mockup/prototype of a new site that is similar to the sites below (using a tool like Invision or Axure)
- mockup includes the full site similar in pages to the sites below (e.g. will have a similar site map), including purchase/checkout process and the required Admin screens and reports
- custom illustrations, graphics, icons, backgrounds, tables, infographics and images similar to the sites below
- a few flyers and postcards for print (design elements will come from the site design)
- site design optimized for mobile, not just simply 'responsive' but optimized for mobile
- create the overall "branding" for the site, meaning the look and feel of all pages
Just use these sites as a starting point and to take some design ideas from. But the point is...these sites are modern, clean, responsive and extremely well designed. In other words, these sites have a really high quality design, and look great. I'm wondering if YOU can create a clickable mockup/prototype for a site in the same domain (food) that also has a very high quality design.
Site: blue apron
This project is just for clickable mockup/prototype DESIGN and BRANDING, not front-end coding.
Thanks for your effort. This should be a great project.
** ** **
WHAT TO DO FIRST, BEFORE I AWARD THE PROJECT: Please do an initial mockup of at least some parts of what the *homepage* might look like and possibly some idea of what the *pricing* page might look like--as well as header and footer. SO I CAN SEE THE QUALITY OF YOUR WORK and your overall direction.
I don't want to see a copy of either one of these sites, but what ideas can you come up with to create a new "brand/branding" (look and feel) for my site? Also, in what ways would you even *improve* on the design/look/feel of these sites?
This is just meant to be a 'test' or 'preview' of what you can do for me. Just please do enough of a mockup/prototype that I can get a sense of your design skills, how artistic/creative you are, and what your overall approach might be. Just give me a SOLID PREVIEW of what you can do.
IN YOUR BID:
1. Confirm that you will do an initial test or preview mockup as I am requesting, so I can see your work and skill level--no milestones for this preview!
2. Tell/show me if you have the skills to do similar illustrations as seen in these sites
3. Tell me how many hours you would estimate for a full mockup/prototype of the full site
4. Confirm how many hours per day you can dedicate exclusively to my project for the next 7 days.

Advantages and Disadvantages of Laptop Computersby Matt Koble
Laptops are the middle ground of the computer world. Smaller than desktops and larger than tablets, they blend the two and provide a balance between portability and functionality. Even among laptops, there are varying sizes. Traveling professionals may prefer a compact 10-inch netbook, while movie enthusiasts prefer a big, HD 17-inch laptop. If you're considering a laptop for your next computer purchase, knowing where they shine and fall short enables an educated purchasing decision.
One of the largest advantages laptops hold over desktops is their size. While desktops have similar functionality, they're difficult to move and traveling with them is highly impractical. While tablets offer more portability than laptops, the small form factor usually limits the quality of the components or their functionality. Netbooks are similar to tablets in that their small size and portability limits the quality, speed and size of components within. The size you see in a laptop's description or name denotes the size of the screen when measured diagonally. So a 15.1-inch laptop has a 15.1-inch screen across the diagonal. Laptops offer portability and desktop-level functionality for most tasks. Like the porridge in the Goldilocks story, laptops aren't too big to carry, but aren't too small to truly limit functionality.
While the price gap between desktops and laptops is getting smaller as technology gets less expensive, laptops are typically pricier. The smaller components required for a laptop often cost more than their larger desktop counterparts since more technology goes into delivering the same quality on a smaller physical scale. That said, if your budget constrains your purchasing options, you can still find inexpensive laptops with lower-end specifications.
For students, office workers and light or average computer users, laptops provide plenty of power, speed and functionality. For PC gamers or people using resource-intensive programs, a laptop might not be the right choice. While some manufacturers offer high-quality gaming laptops, they typically cost more than comparable desktop models.
RAM and Hard Drive
Random Access Memory (RAM) is a large factor in computer speed, while hard drive capacity determines how much space you have on the computer for files, programs, games, music and other data. While desktops used to offer much higher specs in these fields, the gap is closing as technology advances and gets less expensive. That said, it's still common to find more RAM and a larger hard drive in a desktop when comparing desktops and laptops of similar price. As the two main components you can upgrade on a laptop, it may not be as big of an issue to you if you're comfortable doing the upgrade yourself. Laptop hard drives are physically smaller than desktop hard drives, but both have high-end capacities in the Terabyte range, or 1,024GB, with the laptop version being a bit more expensive. While you can also upgrade RAM, the space limitations in laptops might limit the computer's maximum capacity, where a similarly priced desktop might be capable of holding much more.
Laptops don't offer nearly as much customization as most desktops. Since desktops are larger, they're easier to open and alter, allowing you to swap parts and update components. While laptops typically give you access to the computer's memory and hard drive, other components -- like the processor, graphics card and cooling system -- aren't as easy to access and replace. This disadvantage means that when your laptop's non-customizable components become obsolete, you may have to buy a new laptop to keep up with technology. With desktops, you can switch out the obsolete component by itself for much less money than a new computer, extending the life of your current hardware.
While desktops require an external monitor, keyboard and mouse for navigation and use, laptops offer everything you need in one form factor. This advantage means you'll have to buy less external peripherals, also reducing the clutter caused by the extra cords and pieces of hardware. Laptops also come with built-in speakers and often on-board webcams, further reducing the extra peripherals you'd need to buy if you got a desktop. While it depends on the model, many laptops include ports to connect them to your television or an external monitor when you do need a larger viewing area. If your laptop's built-in peripherals don't live up to your expectations, you can always buy external substitutes, like a wireless mouse or keyboard.

When building an application within the specific framework, you must know best practices to write clean and maintainable code. We formed Top Angular 5 Best Practices based on our experience.
So, we invite you to get acquainted with the new features and use those practices in your work.
Angular 5 Best Practices: 5 Tips For Cleaner Code
#1. Project structure
The CLI is the easiest and fastest way to create a new project on Angular. It enables project deployment within a few minutes and develops sizeable apps too. But the main benefit of the CLI is the way of automating pipeline in live development with ng serve and in production ng build -prod. Angular CLI makes it much easier to manage a project. But such simplicity can be translated into inflexibility. This works great for simple projects, but sizeable ones require a manual approach.
#2. Writing components
Components are not a new practice, but it is one of Angular’s core features, so we considered mentioning them. When components are organized and reusable, it is already half work done. Try to be DRY, especially when you have repetitive templates in the application. Rather than pollute components with the same code, consider creating one or several base classes.
The angular application architecture is like a tree of сomponents. We suggest classifying and reusing components to build a more maintainable and organized app. This will provide a clear application structure and build unloaded with similar components code.
You can use Container (Smart) or Presentation (Dumb) Components according to your needs. When you have the component passing properties down to other components, make it Smart.
If there is a component that only performs dispatching actions, better define it as Presentation one.
Data changes in the collection also can affect performance. To deal with this issue, you can use trackBy function. It allows Angular to track added/removed items in the collection by a unique identifier.
We couldn’t help but mention the strongest Angular feature – LazyLoading. It splits the app into modules and loads them on-demand, thus cutting load time.
#4. Use RxJS
Also, developers managed to fix all splitting and tree-shaking shortcomings. RxJS library is a powerful tool that helps to optimize application logic and keeps code clean.
Angular 5 has an effective testing tool. Testing enables us to ensure that certain application parts work exactly as you expect them to. This, to some extent, saves the existing code from breakdowns and helps to clarify – how it will work in various cases. In the end, it allows the detection of code weaknesses.
We would like to describe the main aspects of testing in Angular 5. Choose a test type that fits your situation to simplify the testing process. Also, make sure you know all the capabilities of your IDE in terms of assisting in testing. And finally, you can disable checking the definition for directives and child components. To do so, in the TestBed configuration, write the NO_ERRORS_SCHEMA:
Also, important to mention TestBed alone. It is the utility for simplifying and facilitating a testing process in Angular. We can check whether the component was created and how it interacts with templates and dependencies.
Angular 5 Best practices are not intended to dictate an exclusive course of procedure to be followed or act like a fixed protocol. It is rather a recommendation to keep the project simple and clean. But remember that development is where creativity pays, not the last role.

Today seems to be a day for thinking towards the future…
We’ve been blogging now for 18months and some children have asked about setting their own blogs up. Now we have class blogs and some children have access to write on these. We also have the children’s blog which everyone has access to, but the main problem with this is that after 10 posts, the previous ones are on page 2 and lost into the ether. After-all, no-one clicks on page 2 do they?
I could give them all access to their class blog and then when they blog they put their name in the tag to differentiate it, but each yeah I’d be moving them al around as they move class. I don’t fancy that!
So I want to use WordPress to setup the blogs instead. Now I don’t want to force a blog on every child as the thought of writing more than they need to would scare some children. So I want to do it as a sign-up system. So my initial thought was a google form where the children fill in some options, I look at the answers and then manually setup a blog for them. They could agree to a set of rules before they get the blog turned on and we could decide them with the children of course.
There is probably a plug-in or something that I could use, but here are some things to think about…
- Do I set the children up as contributors so that they can write on the blog – and then I’d have potentially hundreds of blog posts and comments to approve…or do I set them up as a higher level so that they post and manage it themselves – with possible e-safety issues when comments come in
- Is there an automatic way for new blogs to be listed somewhere? There’s no point making new blogs if no-one can find them. I could have a page called ‘Blogs by children’ but would I have to manually make a list of the blogs or could it be done automatically?
- What happens if a child adds photos of themselves to the blog? If the blog was called ‘Amy’s blog’ then photos would have to be banned
- Should the children be allowed to choose their own themes and widgets?
- Should the children’s blogs auto-tweet as well?
Of course I might be thinking of all of this and then it turns out that only two children want their own blog, but still, if two children want it then I should be providing some way for it to happen. I wouldn’t want to be the person forcing them to use non-school systems or worse still, blocking it entirely.
So, if you are a WordPress expert, tips are welcome! If you are a teacher, what do you think? Should children have their own blogs or am I just giving myself more work?

ASCII-TeX to Unicode conversion - possibly using Biber
Writing a converter from ASCII-TeX to Unicode accents is not an easy task. Most converters I have seen fail terribly in not following macros, nested macros, or bear on unmaintainability due to the large set of search/replace patterns one needs to cover infinitely many ways to write something as simple as \'\i in TeX.
Biber seems to do a terrific job at it. It converts accented strings in a Bibliography entry and in the examples I have seen, without a hitch.
Would it be possible to harness this Biber routine to make a full converter for generic TeX files?
the file tuenc.def in the base latex directory has the data you need but what exactly do you want to convert? converting something like \verb|\"{a}| makes \"{a} is tricky if you want to just recognise the second of those cases to change to ä
TeX is not a final output format, most of the time PDF is the target, so the idea is to convert and have the same output... so the \verb|\"{a}| should stay as-is in source so to produce \"{a} in the final output format. This case in particular is simple because the nesting has only one level, but with TeX you can make infinitely harder ones to parse.
yes that is what I mean: so given any package can define a verb-like command that requires that kind of special handling, so an external convertor is tricky the tuenc.sty has the definitions that you need if you want to convert strings within tex, but hard to output a complete document in that case.
note that if i put the above string in a title field biber does the naive translation and breaks it as expected, producing \field{title}{\verb|ä| makes ä}
That is correct, Biber does not work in these instances and it would be desirable to. It is not just TUGboat that has articles with titles like that.
bib2gls uses a primitive parser to perform such conversions, so it can convert \newcommand{\foo}{\"a}\foo to ä but it will also convert $\vec{a}$ to a⃗ (lower case A combining right arrow above) which may not be what you want.
That aspect of biber is just doing a simple string replacement, it is not expecting complicated local definitions, if you use \verb or tabbing (which has local definitions of commands such as \=) or local definitions then you see that it is not taking any account of the tex structure.
The following document has a strange citation but shows tex constructs being passed to biber
\begin{filecontents}{\jobname.bib}
@misc {zzz,
author="Zzzz",
title={\verb|\"{a}| makes \"{a}},
journal={{\renewcommand\"{boo} \" a}},
publisher={
\begin{tabbing}
a \= b
\end{tabbing}
}
}
\end{filecontents}
\documentclass{article}
\usepackage{biblatex}
\addbibresource{\jobname.bib}
\begin{document}
\begin{tabbing}
a \= b
\end{tabbing}
\cite{zzz}
\printbibliography
\end{document}
the relevant fields generated in the .bbl file are
\list{publisher}{1}{%
{\begin{tabbing} a b̄ \end{tabbing}}%
\field{journaltitle}{{\renewcommand\"{boo} ä}}
\field{title}{\verb|ä| makes ä}
all of which would fail to give the correct result in latex, the \= command to set the tab in tabbing has been lost. the \" command is locally redefined as intended but its use has been replaced by ä and the \verb will not show the use of \"
Because of local definitions it would be very hard for any system to completely reliably change all instances of traditional ascii markup that corresponds to a unicode character by that character without breaking any "unxepected" uses of that string. The definitions in tuenc.def give unicode definitions for the constructs but that is expanded while expanding and executing the tex document and so the context is known and you are not trying to preserve the original tex structure.
For a personal document if you wanted to do this, a simple string replace using sed or perl or python etc would convert the document and perhaps require some manual fixing of broken edge cases, but a tool to reliably transform an existing collection of documents without breaking any of them would be much harder.
Indeed Biber mostly uses RegEx and has no notion of more complicated macro definitions or grouping.
@moewe shocking that publisher names set with tabbing are not part of the biblatex test suite:-)

descargar Multidimensional Mining of Massive Text Data en PDF
Unstructured text, as one of the most important data forms, plays a crucial role in data-driven decision making in domains ranging from social networking and information retrieval to scientific research and healthcare informatics. In many emerging applications, people’s information need from text data is becoming multidimensional—they demand useful insights along multiple aspects from a text corpus. However, acquiring such multidimensional knowledge from massive text data remains a challenging task.This book presents data mining techniques that turn unstructured text data into multidimensional knowledge. We investigate two core questions. (1) How does one identify task-relevant text data with declarative queries in multiple dimensions? (2) How does one distill knowledge from text data in a multidimensional space? To address the above questions, we develop a text cube framework. First, we develop a cube construction module that organizes unstructured data into a cube structure, by discovering latent multidimensional and multi-granular structure from the unstructured text corpus and allocating documents into the structure. Second, we develop a cube exploitation module that models multiple dimensions in the cube space, thereby distilling from user-selected data multidimensional knowledge. Together, these two modules constitute an integrated pipeline: leveraging the cube structure, users can perform multidimensional, multigranular data selection with declarative queries; and with cube exploitation algorithms, users can extract multidimensional patterns from the selected data for decision making.The proposed framework has two distinctive advantages when turning text data into multidimensional knowledge: flexibility and label-efficiency. First, it enables acquiring multidimensional knowledge flexibly, as the cube structure allows users to easily identify task-relevant data along multiple dimensions at varied granularities and further distill multidimensional knowledge. Second, the algorithms for cube construction and exploitation require little supervision; this makes the framework appealing for many applications where labeled data are expensive to obtain.

Richard Campbell from the DotNetRocks podcast often says that DevOps isn't a title, it's something that you do. DevOps is the intersection between operations, testing, and development, and rather than having one person specializing in that intersection, it's better to have people in each area gain some familiarity with what DevOps means to them.
I've written quite often about Team Foundation Server (TFS), and the various components that it offers, the ways in which it makes development and deployment easier, and even some of the pain points of the applications. Recently, the School of Medicine spun up a new machine on which we could work with and deploy our new medical education testing software. We had already decided to go all-in on TFS for project management and source control, and flirted with deployment, while also utilizing some of the build functionality to test integration builds, but this was the first time we were going to be able to map out a build and deployment solution from the ground up.
When it comes to Bower, Less, and TypeScript, some people are tempted to put it all in source control, including the generated files. This seems redundant, as each developer machine will transpile and replace the source control version, causing it to be eternally checked out and merged. With Bower, most of those components are used in combination with Grunt to combine or minify output, meaning that although you can check in the Bower components, it could mean a lot of unnecessary files.
There's also the problem of unwanted files on the server. Less and TypeScript files are useless unless you are debugging using source mapping on a testing server. There should be no need for them in production. Same holds for Bower components. On top of that, have you ever had a Bower-intensive project and needed to push it to production? All those files take time to push.
Continuous integration (CI) solutions such as Jenkins and deployment solutions such as Octopus deploy certainly exist, and are very successful, but Microsoft has invested heavily in Team Foundation Server over the last few updates to produce a CI and deployment solution that rivals anything currently on the market, and we were able to take full advantage of it in our situation. In fact, TFS Update 2 finally allows for modern extensions to on-premise TFS (for those extensions that offer it), so the extensibility of TFS is now through the roof, and many of our build tasks take advantage of this.
When you create a build definition in TFS, you have many options for when to build, what source to take, how long to keep the build, etc. We set up a CI build definition that builds the code any time someone checks into the source control. In the build definition, you select steps or tasks to perform in succession. The first operation that is performed is that the code is checked out onto the build server, so every other step that happens occurs within the context of that code set.
NuGet is often a source of never-ending frustration for many developers. It was causing enough pain in our development that we switched to Paket--a package management solution that uses NuGet under the covers, but corrects a lot of the long-standing issues with Microsoft's baked in solution. TFS offers NuGet restore by default, but luckily, Paket is available in the F# extension in the TFS marketplace.
The next step in our build definition is downloading the appropriate bower components. We do not check these files into source control since they won't be the finalized version of our source files. These components will get operated on later by the Grunt task runner.
Something to bear in mind with Bower, Grunt, etc. is that these items need to be installed on the build server. This isn't a big deal, but remember that installing them globally installs them globally for the current user. If your builds are done under a different user account on that server, you'll get build errors telling you that Bower or Grunt or npm can't be found. You may need to install these items locally, but then include them in the system wide environment path.
The Bower build task lets you specify the
bower.json file containing the packages you need installed. If you've been doing
bower install PACKAGE_NAME --save then your
bower.json file should have everything you need. The build step will execute
install by default.
Once Bower is done downloading the various components needed, the next step we have set up is for the node package manager or npm. This means that node.js needs be installed on the system and npm must be globally accessible from the user account that performs the builds.
With this build step, npm is essentially downloading the local Grunt package, as well as the various Grunt task packages needed for the task runner. Much like Bower, npm is looking for a file, only this one is called
packages.json. By default, the task will run the
With the node packages installed, Grunt can now run. We have a
*.cshtml files to replace the individual calls to the JS and CSS assets with the combined and minified versions.
MSBuild (Visual Studio Build)
With all the assets published out, MSBuild can run to build the solution and all related files. This works identical to building with Visual Studio, and will report back any errors or warnings. This has the added benefit of uncovering any environmental issues. Does the build work locally, but fail on the build server? If so, then it'll probably fail in production.
Although unit tests do a fine job at evaluating small units of code, they generally become less useful with most data-in/data-out processes because you end up testing mock data rather than real data. Still, some unit tests are better than none. Running these after the build process gives us an added layer of protection before deployment.
Publish Build Artifacts
Now it's time to put the built code in a safe place. TFS can deploy through a machine copy with release management, and you can point to the built code as the files to push if you publish them out as an artifact. We have our administrative code in one project, but our student-facing testing system in another project--both under the same solution--so we have two tasks for building artifacts: one for each project.
If this were a production build definition, you would want to clean up any unnecessary files, such as the Less and TypeScript files or the Bower components. PowerShell is your friend. TFS makes it simple to create a custom PowerShell script that you can pass arguments to, and then execute. This is the easiest way to finalize your custom build definitions. You'll probably want to run this prior to building out the artifacts.
Since this is our continuous integration build, we can add to it by using the release management tools in TFS to push each build onto the server for testing. When you set up a release, you can point to the specific artifacts to push, decide how often to push, and whether or not the release needs approval (attaching the appropriate people who need to approve the release).
Machine File Copy
The machine file copy release management step uses RoboCopy behind the scenes to push the artifacts from the build directory to a directory on the deployment machine. Once complete, the application is up-to-date and ready to use. We currently use this machine file copy task, but there are extensions for IIS publishing that might be a better option for some people.
Currently, our builds and releases are set up on a CI schedule, so any code that's checked in triggers a build, and if that build is successful, it'll trigger a release. If the build fails for any reason, TFS allows you to automatically have a bug added to the project management portal, assigning it to the person who triggered the build. With this current setup, we've been able to program, build, release, and test at a faster pace than any standard development setup, increasing efficiency, as well as communication amongst various teams.

Running Bulk Restarts Through Control Tasks in XL Deploy
A question I often get from clients is how certain operational tasks, like restarts of application servers, can be done through XL Deploy. They want XL Deploy to be the 'one stop shop', where deployments and simple operational tasks alike can be started.
XL Deploy has a concept for that called control tasks. A good resource to start out from is this blog post, which defines a good, generic framework to start out this specific use case. Browse through this blog post before reading on, it's a short and concise read. The following use case was handed to me: I want to execute a restart on an entire tree of Tomcat servers. The application servers are on hosts, and they are split in a folder hierarchy, like this: So in this case, executing the bulk restart on the folder would restart Tomcat servers on host1, host2, host3 and host4, but executing the bulk restart on the subfolder would only restart the Tomcat servers on host1 and host4. Since 'stop' and 'start' are control tasks themselves, it's like having a master control task that starts child control tasks. First, let's start with defining a new control task on folders in XL Deploy. You simply do that by placing a snipplet like this in the synthetic.xml of your plugin (or in the ext/ folder):
<type-modification type="core.Directory"> <method name="bulkRestartTomcat" description="Performs a stop / start task on multiple Tomcat servers" task-description="Performs a stop / start task on multiple Tomcat servers" delegate="jythonScript" script="utils/bulkRestartTomcat.py"> </method> </type-modification>This tells XL Deploy that on every folder you can execute a control task called 'bulkRestartTomcat' that will invoke a script that runs on the XL Deploy server. We're using a jython script for this control task. The jython delegate runs on the XL Deploy server itself, so you can interact directly with the Jython API. Let's explore how to find the correct servers: by invoking the query method on the repository service (API docs). Here we specify that we want to look for only configuration items (nodes) with type 'tomcat.Server', or in other words, Tomcat servers. The third parameter specifies that we only want to include nodes that are children of the folder the user right clicked on. For the rest we don't have to specify anything.
containers = repositoryService.query(Type.valueOf("tomcat.Server"), None, thisCi.id, None, None, None, 0, -1) print "Found Tomcat containers: " + str(containers)For each of the results, we want to execute the 'stop' control task, and wait for that to finish.
tasks = for container in containers: tasks.append(run_control_task(container, "stop")) wait_for_tasks_to_finish(tasks)And once all have been stopped, we want to start them up again.
tasks = for container in containers: tasks.append(run_control_task(container, "start")) wait_for_tasks_to_finish(tasks)To find the full source including all the details, click here. As you can see in this job log, it found three Tomcat servers on the host1 server:
Found Tomcat containers: [Infrastructure/folder/subfolder/host1/tc1 [tomcat.Server], Infrastructure/folder/subfolder/host1/tc2 [tomcat.Server], Infrastructure/folder/subfolder/host1/tc3 [tomcat.Server]] Executing Control task [stop] for Infrastructure/folder/subfolder/host1/tc1, task id 2617a12a-3e09-4e06-ba1a-dd9f334f36b8 Executing Control task [stop] for Infrastructure/folder/subfolder/host1/tc2, task id 8b6e8125-12fc-42c7-b285-ab7e5b8da050 Executing Control task [stop] for Infrastructure/folder/subfolder/host1/tc3, task id a30e3271-f230-4854-b733-d40dc82d400f Waiting for task 2617a12a-3e09-4e06-ba1a-dd9f334f36b8 to finish Executing Control task [start] for Infrastructure/folder/subfolder/host1/tc1, task id f51d8c13-515c-4b1d-8669-f45c867e2701 Executing Control task [start] for Infrastructure/folder/subfolder/host1/tc2, task id 965bdea6-a662-489c-8369-a4754ad84d33 Executing Control task [start] for Infrastructure/folder/subfolder/host1/tc3, task id a29c6113-634b-400a-8ae9-76bd999ddac7 Waiting for task f51d8c13-515c-4b1d-8669-f45c867e2701 to finishAll the details on the subtasks can be found in the Reports tab under Control Tasks: As you see it's really easy to satisfy these kind of use cases, and especially with the right API documentation and examples within arm's reach. I've packaged everything into a plugin which can be checked out at this git repository.Important: The code linked to is sample code only that is not officially supported by XebiaLabs.

I frequently consult with customers who need to figure out how to better store, consolidate, protect, and manage their SQL databases, Exchange servers, and MOSS farms.
With Microsoft, most of the time I am simply in awe for their long-term ability to seed and harvest a market by slowing slipping innovations into gradually more expensive and higher-quality V2 and V3 products. SQL Server, Zune, SCOM, and Hyper-V are all illustrations of this. But sometimes you get a rogue product group within the company that acts without regards for their overall company strategy. And maybe that’s what happens when you have 65% market share.
I am speaking specifically about how people are being swayed away from using “expensive SAN hardware” for storing and protecting Exchange 2007 data. Not only do the advocates of this approach (which includes the Exchange product team) obscure long term costs by comparing pure “cheap storage” or “DAS” acquisition costs and ignore long-term cost of ownership, they also ignore:
- Management and simplicity of shared storage devices (one place to put stuff)
- Utilization benefits of shared storage device (one place storage means more likely to use it)
- Bandwidth requirements of the CCR/SCR replication scheme which can be 5 times larger than cached replication appliances (say EMC’s RecoverPoint)
- Exchange server virtualization – massive amounts of people are virtualizing their Exchange servers and placing data on a SAN to get the maximum benefit (virtual servers need virtualized/SAN storage to enable most of the advanced features).
Paul Galjan writes a very convincing blog post about dissonance within Microsoft, their latest anti-SAN calculator, and how this anti-SAN stance really backfires when most of the company is aggressively pursuing a very heavy virtualization strategy and taking a more balanced approach about which virtualization platform to use (like ESX being certified under SVVP). I travel around the country giving workshops on how to virtualize Exchange and it’s truly up to the customer to decide whether I talk about Hyper-V or VMware ESX as their hypervisor of choice. At the end of the day, the customer will guide that decision. Not me. I am not paid to push VMware.
If it’s really a cost issue, perhaps customers could chain a bunch of USB drives together and create a super-DAS configuration. But wait. That is pretty close to what they are saying, isn’t it? Get rid of the SAN, get a lot more servers and some cheap disk, and prepare to throw a lot of people at the new storage management problems that will be sure to take place because you aren’t sharing storage across servers, and you’re not sharing global hot spares with hundreds of disks in a system, or taking advantage of a nice big cache layer that smooths out most of the peaks during the Outlook users workday. And not taking advantage of high speed LAN-free backup snapshots or clones for recovery from corruption.
I’ve seen customers trade in SANs and array-based replication schemes for this new model, and only months later come back to an EMC SAN (and replication) saying “OK, you were right… Just don’t say I told you so.”
But it’s not like me to say that to my customers. I warn them up front. 🙂
Some interesting data I’ve been able to gather recently:
- This article talks about the long-term costs of the DAS approach (and did not focus on Exchange specific details such as bandwidth costs, latency, and ease of use).
- SearchStorage article about how a SAN can be more cost effective vs DAS in Exchange 2007 environment.
- And over at HP, we’ve found a friend in a strange place… as their server group is ecstatic about the additional servers required for the DAS solution, yet the EVA team is a little confused. A little Exchange lab testing confirms what I’m talking about (extra latency, difficulty, and management overhead).
- Here’s another reason why SCR could be a sketchy DR solution.
- Another one on the imperfections of this version 1.0 technology, on Microsoft TechNet.
- Oh, and don’t forget to run full backups on this to truncate logs.
- Even the Microsoft teams knows about the various other issues with this replication technology.
- And here’s me on YouTube, trying to sum up why a SAN makes sense for Exchange 2007 (just ignore the really bad hand writing).

Hello, I'm Bop1996, and I don't have much to say here. I am a sysop on the Mario Wiki, so if there's any inter-wiki issues between here and the Mario Wiki, I can most likely either deal with the problem myself or contact a user capable of doing it better than I.
As of whenever the last time I updated this is, I am unable to access a Wii or Gamecube. However, I've come across the means to play Metroid Fusion, Super Metroid, and Metroid: Zero Mission, so once I overcome my appalling lack of anything remotely resembling skill, I'll actually be able to write about these games with something almost resembling coherency, which should hopefully lead to increased activity.
I'm not good at remembering to do things, but if there's something on this list, I at some point want to do it.
- Add boss pics to all the boss articles from Hive Mecha to Helios.
- Create tables showing the locations of expansions, for the pages about the expansions themselves. ON HIATUS.
- Draft or contribute to a revised Citation Policy, as our current one is out of date.
- Create a table for each game, showing the items (but not expansions) attainable within that game.
- Finish the Logbook entries everywhere.
- Create good articles on the red links for creatures in Corruption.
- Get all the locations in the Prime Trilogy (and probably eventually Super Metroid) up to a consistent standard, probably with Chozo Ruins, but there may be a higher standard at that point :P.
- Create a definitive database of dialogue from Corruption (and maybe Echoes, but that may already be on other articles alrready, idk).
- Create a definitive database of scan date for the Prime Trilogy (huge project relegated to when I get some large block of free time and other more important things are finished.
- Create articles on those obscure figures only in statues and lore entries from Corruption, like how we have an article on E-Btr but not Bryyo Fire.
- Significantly boost our Metroid manga content, especially the main page, expand articles such as Old Bird, and create articles like Pyonchi.
- Write Chozo
- Write Space Pirate
- Write Power Suit
- Write Metroid Prime
- Anything inconsistent gets changed asap, especially references and how we do those little things there.
- Destubbify articles everywhere
- Ensure that categories, templates, articles, and the wiki in general are all organized well and intuitively.
Create a creatures-nav for Metroid Prime and Corruption. Fix Samus' article, write or rewrite every Documented Incidents section up to featured article quality, with proper references. Change the Lore articles to all be organized in one consistent fashion (still thinking of how to pull this off) Create a rooms-nav for MP3 (once necessary). Swap infoboxes and categories on creature and plant pages, specifically the Enemy-infobox template and any pages with the Enemies category encountered in that project.

To use GitLabCI/CD, you need: Application code hosted in a Git repository. A file called .gitlab-ci.yml in the root of your repository, which contains the CI/CD configuration. In the .gitlab-ci.yml file, you can define: The scripts you want to run. Other configuration files and templates you want to.
Run our first test inside CI. After a couple minutes to find and read the docs, it seems like all we need is these two lines of code in a file called .gitlab-ci.yml: test: script: cat file1.txt file2.txt | grep -q 'Hello world'.. I just stumbled about an escaping problem with the -e "KEY=value" params. I have to supply two passwords (Database and LDAP for example). The one password contains an ! and the other one.

19/11/2018: better preview, improved input method and preview update performance.
06/12/2018: inspector testing tools: Sample Test allows to quickly test the color resulting from a [0…1] value.
Please note that whilst images in this documentation are still OK for reference they are not up to date and they will be updated as soon as possible.
Unity 3D’s Gradient is a handy data type but comes with some limitations: for example you cannot set more than 8 color keys in its editor and RGB is the only color space available. ColorBand data type offers an alternative with less limitations. Creating ColorBands is fun and easy; they are stored as assets and can be accessed from code through an Evaluate method to get the color at time t, as for Gradient. RGB (or HSV) values are described by individual curves, allowing a better control over how the color function evolves between your points. Color bands are used in all kinds of applications including games, data visualization and other fields.
Examples of color bands you cannot obtain with Unity’s Gradient
- Create a new Color Band asset
Newly created ColorBands will be placed in Assets folder’s root.
- Change its name and its red, green, blue and alpha curves to obtain the desired effect. You can hit Set as filename to quickly set the name from the new color band’s filename. Note that curves’ values should remain between 0 and 1 in both dimensions time and value.
Declare a public ColorBand variable in your script
Assign a color band asset to it
Use it in code by calling the ColorBand.Evaluate(float t) method where t is a floating point value between 0 and 1.
A ColorBand can be discretized which means it will be turned into a set of flat intervals that will return a constant color. To make a ColorBand discrete just set its discrete toggle to true and decide the number of steps the ColorBand will be subdivided into. This will result in discrete bands like the following:
Three different discretization methods are available:
- LEFT_VALUE will build color intervals by evaluating the color at their left extreme.
- RIGHT_VALUE will build color intervals by evaluating the color at their right extreme.
- CENTER_VALUE will build color intervals by evaluating the color at their center.
ColorBands can be described in the two main, standard color spaces RGB and HSV. By default a ColorBand will be set to RGB. When changing color space all the curves remain unvaried but they represent the respective values of the two spaces so that when switching to HSV, the first curve becomes hue, the second one saturation and the third one value. The alpha curve has the same meaning in both color spaces.
- In Unity 5.6.4 and likely in other subversions of Unity 5, there’s color inconsistency between the preview in the inspector and the actual evaluated values. This can be seen when exporting the ColorBand to PNG. A good case to look at is the ColorBand called ‘Red to Blue’, included in the repo. The issue seems to have been solved as in Unity 2017 and 2018 this doesn’t happen.
- In Testing Tools > Sample, the color in the box is not initialized with it’s real value at zero. It falls back to black instead.

You need to add a specific converter factory when creating instance of Retrofit client see BuilderaddConverterFactory method for details. If you used Retrofit with Java before you know that we need to define interface where we will describe our HTTP requests, functions to trigger those requests and expected response types. In Kotlin it is similar but there is’t so much code and it’s really easy. In our ArticleApiClient interface we will define. Retrofit is a very popular networking library by the good folks at Square, and it is widely used in the dev community. Even Google uses it in their code samples.

The main problems arn't game-specific, but i'm running ISBoxer with RIFT (1x Warrior, 1x Cleric, 3x Rogues), so i'm using examples/terms from that game.
I created 3 clickbars so i can switch my rogues to either "bard", "saboteur" or "ranger" mode.
That's because those "modes" use different "main attacks" and different "finishers".
my main character is the warrior which kinda always is "hot".
every hotbarkey-press results in a "main attack" execution on my 3 roques.
i got an exctra hotkey to only execute the rogues "finisher".
in this szenario i will use:
bard = 1x main attack (Cadence) / 4x Finishers (different Codas)
rogue = 2x main attack (either Blast Charge or Spike Charge) / 1x Finisher (Detonate)
ragner = 1x main attack (Quick Shot) / 1x Finisher (Head Shot)
So the main clickbar consists of 3 buttons (bard, sabo, rang).
(in this pic, the "ranger" button is selected to show only the mainbar, cause i don't have a "finisher" button for ranger yet)
if the "bard" button is clicked, an extra clickbar appears to choose the type of "finisher". debuff finisher selected here
if the "sabo" button is clicked, an extra clickbar appears to choose the type of "main attack", cause "finisher" is always same (at my lvl/spec). Blast Charge selected here
so...main clickbar is always present.
"bard finisher" clickbar is only present when "bard" is selected on mainbar.
"sabo main attack" clickbar is only present when "sabo" is selected on mainbar.
"ranger finisher" clickbar is only present when "ranger" is selected (ranger finisher not done yet, but you get the idea)
whatever i choose from mainbar (and then on the associated finisher/main attack clickbar) is shown in color, all other icons are greyed out on those bars.
this works exactly as it should and ofc it also "remembers" what i selected before.
i click "bard" + "debuff finisher" and then i switch to "sabo" + "Blast Charge main attack".
if click back on "bard", the "debuff finisher" is still highlighted.
same goes for "Blast charge" when i switch now back to "sabo".
currently i always need to select the "finisher" again when i switch on main clickbar.
1. i start and select "bard" + "debuff finisher" - working correctly.
2. i switch to "sabo" and select "blast charge main attack" - working correctly.
3. i switch back to "bard". the "debuff finisher" is still highlighted "visually". spamming main attack works corretly. but finisher hotkey uses "sabo finisher" cause that is still virtualized. - error (should use bard's "debuff finisher" here. need to click it again to work correctly)
1. i start and select "sabo" + "Spike Charge main attack" - working correctly.
2. i switch to "bard" and select "debuff finisher" - working correctly.
3. i change to bard's "heal finisher" - working correctly.
4. i switch back to "sabo". "Spike charge main attack" is still highlighted "visually". spamming main attack behaves wrong here, cause "main attack" is still virtualized as bard's "main attack" (cadence). finisher hotkey works correctly
i hope this shows my problem and it's understandable.
i could live with those few clicks now, but im planning to increase the amount of clickbars/icons and it would be very helpful to somehow remember the keymap previously used.
it would also make it possible for me to do "feature-rich" clickbar menus.
if you know how to solve this problem or could shed some light into this maze, i would highly appreciate it and prolly others too
don't be shy and tell me i'm doing something absolutly wrong!
(I'm still new to ISBoxer, but very excited about the possibilities.)
Thank you for your time (text got longer as i thought)

I was at the DDD exchange recently where we had the likes of Udi Dahan, Eric Evans and Scott Wlaschin on the panel. In a post event Q&A session I asked the panel - “Is microservices SOA renamed? “ which triggered an hour long debate. The panelists argued amongst themselves about what exactly a service or a microservice means. By the end of the debate I doubt any one of us was any more wiser. Clearly there was no consensus on the definition of the word service and what it means. It is a term that is widely used and abused in our industry but we do not seem to have a common understanding of it. This raised a few questions in my head. Disappointed with the expert advice, I decided to look out for a definition of my own.
The dictionary tells me that a service is - “the action of helping or doing work for someone”. Is a microservice significantly different from this definition? In order to come to a definitive answer, lets recollect the knowledge that is already out there.
“ Microservices aim to do SOA well, it is a specific approach of achieving SOA in the same way as XP and Scrum are specific approaches for Agile software development.” - Sam Newman (Building Microservices)
Now according to SOA (Service orientated architecture) a service has the following tenets:
- Services are autonomous - Cohesive single responsibility.
- Services have explicit boundaries - Loosely coupled, owns its data and business rules.
- Service share contract and schema, not Class or Type or a Database
- Service compatibility is based upon policy - Explicitly state the constraints (structural and behavioral) which the service imposes on its usage.
These tenets do not appear to be too different from the object oriented design principles. Can we define a service based on the above principles? Lets look at the tenets a bit closely.
What is a Service?
- Autonomy of a service suggests it is independent of other services to perform its tasks, therefore in order to be independent it needs to have one and only one well defined responsibility. Uncle Bob has summarised SRP rather fittingly - “Gather together those things that change for the same reason and separate those things that change for different reasons.” In short a service should not have more than one reason to change.
- Boundaries are drawn to restrict free movement and ensure all movement is governed by a set of rules. In the context of a service this restriction is enforced on free movement of data across a service boundary. All data and business rules reside within the service imposing strict restrictions on any movement in and out.
- Services interact with other services through a shared contract by sending messages. These messages contain stable data (i.e. immutable, think events). The data going through service boundaries is minimal and very basic.
- Usage of a service enforces certain constraints, the incoming messages conform to an expected structure and format.
What a service is NOT?
- Anything with the word Service appended to it does not automatically qualify as a service.
- A service that has only a function is a function not a service, like calculation, validation (not be confused with DDD’s Domain Services which is a more granular concept). Making it remotely callable through RPC/SOAP still does not make it a service.
- A service that only has data is a database not a service. Doing CRUD through REST over HTTP does not change that.
Philip Kruchten’s 4+1 Architecture View Model describes software architecture based on multiple concurrent views.
4+1 Architecture View Model
I see defining services as breaking an overall system into smaller isolated sub systems so that adding features to the overall system requires touching as few sub systems as possible. This decomposition can be at the
logical level (business capabilities - the reason for something to exist),
component level (dlls, jars, source code repos),
process level (web app, http endpoints) or the
physical level (machines, hosts). Bounded context in DDD terminology focuses on the logical separation whereas Microservice focuses on the physical separation. The philosophy of slicing up your system into manageable chunks still remains.
What is an Actor?
The Actor model allows dividing a system or application into smaller isolated tasks or actors that can run concurrently. When an actor wants to communicate with another actor, it sends a message rather than contacting it directly, all messaging being asynchronous. Traditional approaches to concurrency are based on synchronizing shared mutable state which is difficult to get right. Wouldn’t it be better not having to deal with coordinating threads, synchronization and locks? Actors achieve this by changing internal state between processing messages but avoiding sharing state. When there are no shared state mutations, synchronization and locking are no more required. Apart from concurrency and performance gains there are other benefits with the actor based approach like hot code replacements.
Having closely looked at the SOA tenets that govern the service partitioning rules and the levels at which partitioning can occur, be it a service, a microservice, an actor or even an object what we really want is isolation. We want a small computer with private memory that you can interact with through a contract. This small computer can also be an object. In Smalltalk 1971
An object is a little computer that has its own memory, you send messages to it in order to tell it to do something. It can interact with other objects through messages in order to get that task done.
We often break encapsulation by sharing private memory through public getters and setters on objects in languages like Java and C#. Actors enforce this isolation by restricting access to private memory (internal state). You can apply the same isolation principle to a service or microservice.
Each service has its own process boundary. The contract is a service updates it's shared memory and exposes a mechanism to read from its shared memory but the service itself is the only one that is allowed to write to it.
Adding features to your system will invariably involve touching more than one sub system at a given time but depending upon how well the system has been partitioned, ideally it should involve touching as few sub systems as possible. Loosely coupled systems allow failure isolation, allow services and consumers to evolve independently of each other and lower the risk of future changes, therefore reducing complexity, effort and cost.

Keyboard map is incorrect when using an NX-client
I have a problem with nomachine NX-client in Ubuntu. It seems that the keymapping has a problem. For example, the arrow keys do not work (except for up key which opens printscreen!). I searched online and found several solutions. However none of them worked for me:
solution 1)
On the server, change System->Preferences->Keyboard->Layouts to “Evdev-managed keyboard”
The server that I log into has Centos 5.7 on it and I cannot find “Evdev-managed keyboard” layout in keyboard setting. I tried several other generic keyboard layouts with no success.
solution 2)
add the following lines to /etc/X11/xorg.conf:
Section "ServerFlags"
Option "AutoAddDevices" "false"
EndSection
I did it and my keyboard stopped working completely! I had to use the on-screen keyboard to remove this setting and get back to normal.
solution 3)
Run xmodmap -pke > localxmodmap locally
Copy the file to server as .Xmodmap
Run xmodmap ~/.Xmodmap from terminal.
which gives me a bunch of errors such as:
xmodmap: /home/fzc23/.Xmodmap:60: bad keysym name 'XF86Switch_VT_1' in keysym list
and doesn't work.
I do not know what else to do. I would appreciate if somebody could help me out.
BTW, the NX-client on windows connects to the same server with no keymapping problem so I believe this is a problem in Ubuntu and has nothing to do with the server side.
I had the same problem under Gentoo. I can't promise that this will work on a CentOS 5 server, but this worked for me on a Gentoo server.
Inside your nx session, open a terminal window and run:
setxkbmap -model evdev -layout us
Replacing "us" with your desired layout if it isn't the US layout. Your keymap should be correct now. If you start your nx session using an .xsession/.xinitrc style script, you can add the setxkbmap command to the startup script.
NX broke for me on both Windows and Linux clients after installing newer versions of xorg with evdev keyboard drivers, but this command fixes it whenever I log on or resume a session.
I solved the problem by going to Preferences → Keyboard Shortcuts and selecting Desktop → Take a screenshot.
The setting there showed (seemingly correct) Print. However, I removed it by clicking the entry and then hitting backspace, changings it to Disabled. After that my cursor up key worked again.

SCJP 1.5 Tips from Real Exam Takers
Originaly posted by Srimadhava Reddy here :
1. Kathy Sierra & Bert Bates is the best book for this exam.
2. Read the book 2 or 3 times & Clearly understand the topic and do all the questions given in this book
at end of each chapter.
3. Clearly understand the rules for overloading and overriding.
4. Get familiar with the API for Date, Calender, Locale, DateFormat, String, StringBUffer & StringBuilder.
5. Write Simple programs to make it clear for Regular expressions & Static imports.
6. For I/o, Serialization follow the steps. Like creation & working with directories,
Storing and reading data to and from file, etc.
7. Clearly Understand how the boxing & unboxing is working.
8. Familier the API for Array & Collections classes.
9. Make it clear in var args and Conversions (Wrapper to primitive & vice versa)
10. In Collections Clearly understand how we can override hashCode and Equals methods.
Familar the differences between all the Collection interfaces and Classes.
11. Threading, good book is ks&B one only. Read 2 or 3 times and do all questions given.
If You want to pass, that book is sufficient.
For Generics & Collections, Enums & Var-args I followed the mock questions from java-beat.
They are very good. Especillay for all new topics which are introduced for 5.0 they covered vey well.
Mocks exams done by me:
- 1. Kathy Sierra & Bert Bates book questions + 2 mock exams (They are tough compared to real exam)
- 2. Mocks exam question from java-beat.
- 3. http://www.danchisholm.net/ (for all old topics).
- 4. http://faq.javaranch.com/view?ScjpMockTests (You can get some question from that).

Following are some tips that i want to share with u all who are
planning to give SCJP 1.5
Please master in rules of overriding and overloading , coz almost
all the questions test ur knowledge of overloading and overriding
Make ur concept clear for boxing , unboxing, wrapper to primitive ,
primitive to wrapper .
Criteria for selecting appropriate overloaded method when there are
2-3 methods overloaded with Object, Primitive, Var args as an
For file i/o, Serialization get thorough with steps , u will
mostly get drag n drop questions on this section .
String , string buffer , String builder get familiar with API
Threading , Synchronization …… Generics and Collections -- get
thorough with Collection and Array API .HashCode and Equals
overriding , Generics concept , Generic classes.
Special thanks to Javabeat.net's mock up questions for this
sections . The generics concept which is given in Kathy book is good
but to get thorough with each and every syntax when u use generics
we need some more material . There are many ways by which u can
declare generics (with warning and without warning compilation )
and use it . And u need to understand it more critically since here
we do have one more answer "compilation with warning or without
warning" in the options given .
I suppose the material that I referred for this topic which was
provided by javabeat.net mock up questions was really great , It
not only helped to get generics concept clear but also boosted the
confidence to play with generics questions .
Othere topics that I liked from this material was Enum , Var-args ,
Boxing unboxing and File I/0 .. Since these are new topics included
in scjp 1.5 . we need to focus more on these new topics .(It is
obvious that we should be good in other topics also but we can get so
many questions on these old topics from hundred of sites ) By
reffering questions which are given at the back of Kathy’s book u can
get exam cleared but if u want to get good score u have to go through
different types of questions on these new topics .
All The Best !!!!!!!!

Our World Statistics Day conversations have been a great reminder of how much statistics can inform our lives. Do you have an example of how statistics has made a difference in your life? Share your story with the Community!
There's a bit of Latin that states "omne trium perfectum" or "everything that comes in threes is perfect." I had not set out to write three posts in a row on Markov Chain Monte Carlo (MCMC), but sometimes the stars align in such a way that the story continues to write itself.
But first, a joke:
A Bayesian and Frequentist apply for the same job. The interviewer tells the Frequentist, "Sorry to tell you this. You're a great candidate, but we decided to go with the Bayesian." The Frequentist is disappointed but says, "I understand, but can you tell me what tipped the balance in her favor?" The interviewer says, " On paper, you both have the same qualifications. However, the Bayesian has prior experience."
This post is actually the result of some feedback we received from one of our JMP users who frequently fits models using WinBUGS. While he found the MCMC Diagnostics add-in useful to explore posterior samples, he found it difficult to get WinBUGS output into the appropriate form. He sent me the following example to work with: Wolfinger (1998) analyzes tensile strength measurements for a composite material used in aircraft components (data in Table 4 in Vangel (1992)) using a model with 8 parameters. Requesting 11,000 posterior samples (assuming the first 1,000 are burn-in samples that will be tossed) for a single chain generates two output files in WinBUGS. The first, index.txt, is a list of parameters with the starting and stopping observation numbers. For this example, the contents of index.txt look like so:
a 1 11000
a 11001 22000
a 22001 33000
a 33001 44000
a 44001 55000
mu 55001 66000
sigma2.a 66001 77000
sigma2.e 77001 88000
The second file called chain 1.txt contains 2 columns. The first column is the iteration number 1 to 11,000 repeated 8 times, while the second column contains the sampled values for the 8 parameters; essentially an 88,000 x 2 matrix. How can these output files be used by the JMP MCMC Diagnostic add-in (which assumes rows are samples within chains and columns are parameters)? Just apply the freely available WinBUGS to JMP Conversion add-in! (Download requires free SAS profile.) The add-in asks for the directory location of WinBUGS output files (index.txt and chain 1.txt, chain 2.txt etc) and creates a JMP table called MCMC Samples (which can be saved with a new name). See Figure 1.
Figure 1. JMP Table of MCMC Samples Converted from WinBUGS Output Files
A few points to consider. First, the data table in Figure 1 includes the first 1,000 samples that were intended as burn-in. I can either delete the rows from the table, or exclude the rows from analysis by selecting the first 1000 rows, right-clicking and choosing "Exclude/Unexclude." This causes the MCMC Diagnostics add-in to ignore these rows as if they were not present. I can always Unexclude later if I would like to examine the burn-in samples in further detail, say, to assess the speed of convergence in trace plots. Second, notice how the parameters a were renamed as a_i. This was intentional so that variable names were not interpreted as an array by the conversion process. Make note of this as you name your parameters within WinBugs, since the conversion may result in columns with duplicated names.

Let's open up the main terra form file, located directly underneath the 03 modules. Here's the Resource Group are referencing to the custom resource group module that we were reviewing just a moment ago.
And then you can see there's reference to two additional modules in this terra form file. And if you look at the source path unlike before, it's not a relative directory path. It's this kind of absolute path, and that brings us to the concept of the terra form module registry and community pop modules.
So if you look here a TTE the get website, you'll see we have
a link to additional Resource is going to take a moment to navigate over to the terra form registry, which is where you can find all sorts of community modules Summer verified. They have these little stars of here. Some are not. So you're gonna want to take that into account when you're evaluating a module on determining what Mongols do I want to work with
they may not all be from, ah source that is as legitimate. Or you may want to investigate some of the details of the module a little bit before using it. In this particular example, we're using the compute module, which you can see here it is in his er verified module.
Um, it's being produced by as there are m. So
I like that. I like to feel a little bit of ah legitimacy around this one. And in the documentation it describes, what are the different required inputs when you're creating and using this particular module for the compute? There's also a module that we're going to be leveraging as well called the Viet module again, this has been a verified module,
So we like that and we can look at the documentation and understand
all the different inputs outputs, dependencies, that this model has.
If I flip back over to our source code where we're using this module, you notice that it's all yellow. The idea is not too happy about things right here. And basically what it's saying is, I don't know about this model. I don't know how to find it. I don't have this information loaded in my directory,
so I want to drop down to the command prompt Here,
located in the 03 Modules directory, I'm gonna run terra form and mitt.
What this will do is what it's done. Always in the past is download. This particular providers, like is There are M, but you also know it is here it is downloading a copy of the different modules into a certain sub directory, and I could definitely navigate there and look at the code of that model. In fact, it is a If I wanted to do it and in depth audit, I could do that.
Or I could just even look at other people's terra form code.
You could definitely learn to develop your coding skills and understand how different people are kind of pushing the boundaries of terra form. Take a look at those some maybe good practices. Some, maybe not. But it is definitely a great way to learn how to improve the quality of writing of your terra form code. By
seeing what are some of the other people did using and
how they assembled these kind of things.
You'll notice that the I D. Stopped being yellow in this area of the network module. That's because when I ran, the Indebted downloaded those modules. The I D picked it up,
and now it has a good bearing on what are the different inputs of this type of a module? Which ones are required? Which one or not? We can see they're showing up here in the auto sensing. In this particular case, I'm really just filling out the very bare minimum values
for this particular model of the network, giving it a location giving it a resource group
and the values of the location. The resource group. I'm actually referencing the outputs from the resource group module that we created custom, and we're reviewing a bit earlier, Right research group, location and name similar approach being done down on the computer model.
And you'll also see specifying the operating system to be in a boon to server.
Ah, and I'm even specifying that this server runs on a sub net. And rather than hard coating that in basically saying, you know, the virtual network that this other module created, where you're going to be using that just used the very first virtual sub net located in the V Net that was defined
through the use of this module
and one last element about this main terra form script that you probably noticed is Ah, resource called random I d. So this is not ah, resource provided by the user r M It's not cloud specific resource in this circumstance. When we create a server, we want to assign it a D. N s name, and
all the N s names need to be unique.
So to ensure this, what we're going to be doing is leveraging this random i d. Resource. You could definitely read more about this. Stop is leased a random number generator. I'm giving it some particular specifications of length to be eight for the generated by random i D.
But another important thing here is the keepers.
So this random i d is on Lee generated or regenerated and re evaluated. If the the name, the value of the group i d for the resource changes, that's way when I'm running it again and again and again, it's not going to be generating a brand new random
I d. Every single time.
That would be good, because let's say I want to deploy this as is, and then I want to come back and I want to say allow sshh traffic to be false, and then I will do the plan in the apply.
But when I'm running it, we don't want the d. N s for the server to change. The only change that I want to take place is allowing the SS H traffic and you're not allowing as shh traffic in that circumstance.
What's up? Back over to the command. Prompt and run a terra form plan and see what Terra Form thinks needs to happen in order to
do what we've specified here, which is creating a resource group were specifying that activity by applying a model. We're using another community model and saying created virtual network. And then finally with the module, we are saying creating a server which will be a simple of room to server. And as we can see
here, there are a few actual warnings about some deprecate ID stuff, and they're coming from the
the modules that I'm using and it doesn't look like it's critical, but it But it is a warning will continue to use this module, but something to keep in mind as we're tapping into community modules. There's nothing that we can do directly Thio to fix that unless we wanna make a contribution to the open source community,
is where this particular model is stored on Get hub. Believe it or not,
in fact, just a just a quick tangent you can see here is the actual location in Get Hub. So if I did want to make a contribution to add via get help, I certainly could. In this case, I'm not too worried about it. It's just a warning about a deprecate ID property
looking down a terra form plan. We can see it's creating sub nets. It's creating a hole,
a whole lot of things in terra form for me, even though my actual terra form file is pretty simple, really, we have three different modules being referenced, and then we're using the random I. D. Resource teen calculator Random value. That's going to be the D. N s name. The public being s name for this, a boon to server.
So this is where the
the using of patterns of a module these models here, this compute module has defined creating network security groups. In addition to just creating a server, it's assigning it to the virtual network.
You can see we have some security rules so There's really a lot that these models were using
are are doing for us. But it's abstracting us from needing to deal with so many details and fact. What I'd like to do right now is go ahead and launch and apply this so that this server and the resource groups and the networks are all gonna be created.
It will just be a second looking at what gets done
for us automatically by using these models on, then that will just really underscore how much heavy lifting and the particular pattern that they're using in the module to implement creating a virtual network and creating a particular server.
So I'm gonna go ahead and apply this. It will take a little bit of time someone a fast forward in time on the video.

Text was truncated or one or more characters had no match in the target code page When importing from Excel file
I have an excel file with four text columns:
one of them is called ShortDescription which has the longest value.
I created a table in SQL Server 2008 database, with four columns and the ShortDescription column type is set to NvarChar(Max).
but when using the SSIS import and export dialog, I keep getting the mentioned error in the title, even when I set the OnTruncation option to Ignore.
I tried to clear the column data, and it succeeded (so I made sure that the problem is in the ShortDescription column).
I tried to copy the whole data to another excel work book, and still no luck.
any ideas ???
I assume you're trying to import this using an Excel Source in the SSIS dialog?
If so, the problem is probably that SSIS samples some number of rows at the beginning of your spreadsheet when it creates the Excel source. If on the [ShortDescription] column it doesn't notice anything too large, it will default to a 255 character text column.
So to import data from a column that contains rows with large amounts of data without truncation, there are two options:
You must make sure that the [ShortDescription] column in at least one of the sampled rows contains a value longer than 255 characters. One way of doing this is using the REPT() function, e.g. =REPT('z', 4000), which will create a string of 4000 of the letter 'z'.
You must increase the number of rows sampled by the Jet Excel driver to include such a row. You can increase the number of rows sampled by increasing the value of TypeGuessRows under the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Excel (of if your system is x64 then under the HKEY_LOCAL_MACHINE\SOFTWARE\wow6432node\Microsoft\Jet\4.0\Engines\Excel)
registry key.
You can see more information at these two links:
http://waxtadpole.wordpress.com/2008/04/28/hello-world/
http://technet.microsoft.com/en-us/library/ms141683.aspx
To further explain, SSIS creates 3 objects behind the scenes of the wizard, an Excel data source object, a SQL table destination object, and a data flow operator between them. The Excel source object defines the source data and exists independent of the other two objects. So when it's created, the sampling I described is done and the source column size is set. So by the time the data flow operator executes and tries to pull the data from excel to put in your table, it's already looking at a data source that's been limited to 255 characters.
that is amazingly right !!! but why is that happening if the destination column is set to accept maximum length of data?? so what the length of source column has to do with it???
"Note For 64-bit systems, the corresponding key is as follows:
HKLM\SOFTWARE\wow6432node\microsoft\jet\4.0\engines\excel " - link
But apparently the value can only be up to 16? Doesn't seem to be much of an improvement - but I haven't tested it.
For me, sorting the rows with longest text at the top worked. @NourSabouny, I think he's saying that the data flow operator in the middle is erroring, even if the destination column is set to nvarchar(max).
I had this issue when importing from a flat, delimited file into SQL Server. The solution was to update the 'OutputColumnWidth' value for the offending column (from the error message). On the 'Choose a Data Source' form in the import wizard, my source was the flat file. On the leftmost pane, choose 'Advanced'. You can then set the properties of individual columns. In my case, the 'OutputColumnWidth' for most of my columns was defaulted to '50'. I simply updated it to a larger value that would not truncate the value from the flat file.
Alternatively, rather than guessing a large enough limit to a DT_STR, you can choose the DT_NTEXT SSIS type, which is the equivalent of the MSSQL nvarchar(max) or the obsolete ntext types.
A combination of updating the OutputColumnWidth and using DataType DT_WSTR worked for me. In SQL Server 2014, DT_WSTR can have an OutputColumnWidth up to 4,000 Unicode characters wide. This resulted in something similar to 40-Love's answer below.
Can you change all of these columns at once? I have a high amount of columns and I was wondering if this was possible.
This was my problem. +1
A simple way to get it to work is edit the file you want to import and create a new row in the first spot. That way it will always be sampled. Then for any columns that may have >255 characters, just add 255 characters to the cell and it will work. After you import, just delete out the junk row you added.
This was the shortest path to success for me.
Hmmm, not sure how this is different from the solution. This solution seems more appropriate for stackexchange. ~(:
I got this error when I was trying to import a large file that had some chinese characters in it, and also some invalid (large) strings.
The text file was saved in UTF8 format.
My settings:
On the General Option (didn't change anything):
- Locale: English (United States)
- Unicode: Unchecked
- Code Page: 65001 (UTF-8)
There is an Advanced Option on the left
- DataType (for column): Unicode String [DT_WSTR] (changed)
- OutputColumnWidth: 4000 (that's the maximum) (changed)
On the Review Data Type Mapping
- On Error: Ignore
- On Truncation: Ignore
My target column had width = 50.
I got no errors with these settings.
Thank you for posting this. I was receiving the same error message during my imports, caused by the issue mentioned above: attempting to import data having foreign characters into fields with data types that did not accept foreign characters. My fix, short-term, was to remove the foreign characters from the data I was trying to import.
There is an alternative location of the registry component that needs to be changed to resolve this problem.
If you cannot find it at
Start–>RUN–>RegEdit–>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Excel
then look in
Start–>RUN–>RegEdit–>HKEY_LOCAL_MACHINE -> SOFTWARE -> Wow6432Node -> Microsoft -> Jet -> 4.0 ->Engines -> Excel
For me this link helped me : https://support.microsoft.com/en-us/kb/189897
Copy the row which has cell value > 255 characters to the beginning of the excel, make that row the first row in the excel
change the registry value from the above link.
Try this -
Go to Data Flow Task > Right click on Excel Data Source > Click on Show Advance Editor > Select Input and Output Properties > Expand Excel Source Output > Expand External Columns and Output Columns and check the erroneous columns and click on those column headers and update Data Type accordingly (Mostly that should be Unicode text stream [DT_NTEXT], otherwise change to that and give it a try).
Hope this help.

The MCSD covers a number of certification areas, together with Windows Store apps, Web purposes, SharePoint purposes, Azure Solutions Architect, application lifecycle management, and Universal Windows Platform.
Computer ScienceSoftware EngineeringHow do the fields define and differentiate themselves? Computer science takes a broad method to the research of the rules and use of computer systems that covers each theory and software. Combining enterprise knowledge with computing expertise, enterprise data analysts assist companies translate enterprise needs into technical solutions. In their position, enterprise information analysts draw upon an analytical skill set to research, plan and manage how information systems and software can be utilized to unravel enterprise issues.
Software engineering requires a comprehensive technical skill set and data base that ranges from understanding enterprise necessities to testing products. Below is an inventory of the core software program engineering competencies from the National Workforce Center for Emerging Technologies.
Software design Students ought to anticipate to examine totally different programming languages and learn the way their explicit traits can be utilized to software creation. Mathematical modeling Students are launched to mathematical fashions, which have purposes in understanding and predicting pure phenomenon and human nature. In truth, most entry-stage software engineering positions would require this four-year degree. Some more superior positions might require a grasp’s degree in software program engineering. In that case, a bachelor’s diploma might be a prerequisite to admission.
Software engineering is the applying of engineering rules to laptop hardware and software, usually to resolve real-world issues. Computer science is the appliance of the scientific technique to computer software. Computer science is broader and more abstract and is used for theoretical applications than practical ones. Officially, it’s the appliance of engineering rules to software program design. In plain language, software engineering is a field in which hardware design and system computation come together.
The architectural design of net functions, as well as programming languages and technologies to help build internet functions, are reviewed on this class. An affiliate diploma in software program engineering takes about two years to complete. The associate diploma can be a useful means for college kids who need a degree to tackle an entry stage software engineering position without spending the money and time getting a 4-12 months degree.

Effective working at audio/video editing sessions (avoid fatigue making steady progress)
Background
I've just completed an editing project to produce video highlights of an awards evening for my local community radio station. It was a voluntary non-paid project and I'm very pleased the results I achieved - and more importantly, the station are very pleased with it too. But, as with many other previous projects, have found editing can be tiring at times. I have a full time job in computing but unrelated to video editing (funds all the software and equipment that I learnt this stuff on!) and usual housekeeping commitments so I had to produce this work from a number of sessions, some into the early hours. When I know I have to resume the work to get it done I procrastinate and do other jobs sometimes before I finally get in the zone, once in the zone I get frustrated when I have to stop to meet other commitments: sleep, work etc.
Any top tips to bear in mind for a future project?
Maybe this question is too broad for the Q&A format here. In my view the question is actually applicable to any project based work, be it video editing or illustrating a book.
+1 Thanks for your input. I guess the difference between editing and illustrating a book might be that with editing you start with raw content whereas with illustration you might sometimes start from scratch. Where they are the same is that both involve iterative work, going over the same content to refine.
This is an interesting question and I think maybe you are coming from a different situation than I am, I worked as a professional editor / VFX Artist and before that assistant editor for many years before graduating to directing and I think the easy bottom line answer is, if you love it, you wont be able to get enough.
However there are those days your like screw this im surfing the web or this and that. Which are a given.
I really loved what I was doing and while I may sit on a project for two years every day was a new day and every day brought new challenges, both technical and editing related. I tend to work an area until I am bored with it or until I get in the zone, and then move around. The longer the job the more things that need to be done etc.
After awhile it just becomes clockwork and you dont think about whats going on in the world, tunnel vision just becomes so normal to you when you sit in front of your system that when your there, its work.
When its time to go, its time to go, and also I think setting a time limit. If I sit down I wont work more than 7 hours, if I work more then I feel like I can always work more, which is fine when you have deadlines, but if your always letting yourself work too much, you'll get burnt out and hate doing it.
Hopefully something in this answer helps
Are you for hire? 7 hour workdays and you have to stop yourself... Wow. If I get 5 hours editing in in one day, I exceed my goal.
OK, I'll have a go. Here's my own answer (and advise I should take for myself - which I actually did do to some extent):
Avoid procrastination. Start small. Start with doing something. Don't hold up too high expectations to put yourself off. Good ideas here: http://zenhabits.net/dead-simple-guide-to-beating-procrastination/ (I succeed a bit with this advice, BTW I have no affiliation to zenhabits)
Regularly deliver draft work in a complete state to the customer. This rewards you. It gives them confidence that this is being done. It gives them opportunity to give feedback during the process (to avoid unnecessay work or deviation or disappointment). It gives them something to do on in the event you are delayed later, due to illness or other commitments.
Take breaks.
Track progress to help predict how long the remainder may take.
I'd welcome anyone else's input. I'm really answering here because no-one else has yet. I'd welcome some enlightenment from your own experiences.
I'm in a very similar situation to yours. I'm a software architect that also does a professional level of A/V work on the side as a professional hobby. The time commitment can be difficult at times, but I have always found that putting aside blocks of time is the best way to make solid progress. I find that if I try to do it small bits at a time, it tends to give the end product a bit of a fractured feel if I try doing it 30 minutes at a time here and there.
It sometimes means I only get one or two times a week to work on a project, but I try to put in at-least 2 to 3 hours to a session. More if I can manage on a weekend. For larger projects, I'll try to get everything done I need to during the week so I can just dedicate most of a Saturday to it. I'll actually probably be doing just that this Saturday since I have a back log of photo and video work to post produce from the last two weeks (a birthday party, two work parties and a weekend conference from last weekend).
Oh, also, try to plan out what you want to do before you do it. Having a good idea of the full picture lets you move around while working on it between different aspects of the project. It takes some practice to figure out what bits you can do in what order, but finding ways to be able to change things up while not interrupting your flow tend to be helpful in avoiding fatigue of logging clips for 3 hours after spending a long day at the office writing code.
+1 Thanks @AJ Henderson for your experience! I will leave the Question open for other contributors and then look at closing.

Multi social share is a sharing app for both Windows 8.1 and Windows Phone 8.1 using the new universal apps technology. Multi social share allows you to configure and connect your social networks, like Facebook, Twitter or LinkedIn and connect to your OneDrive account.
As Multi social share is a universal app, it can share the settings between both versions. So if you connect your accounts in your Windows Phone, when you launch the app on your tablet all is configured for you.
Another great feature of Multi social share if the file reuse option. As uploading files to the cloud (OneDrive in this case) is data intensive, you can activate a reuse fles option, that allow the app to look for the file name of the file it is uploading in each moment. If the file already exist in OneDrive app folder, it don’t upload it again, instead, it is going to get the public url of the file and short it using the is.gd shortener service integrated in the app.
For posting an update, you simply need to open the app, select the social networks to share with (you can configure what networks are selected by default) and write your update and tap the “share it” button.
But the real value of Multi social share is found on it integration with the system share system. Multi social share works as sharing target for:
Images: jpg, bmp, gif, png
Other file types
So, both in Windows Phone or Windows tablet/pc, you only need to go to your favourite page in internet explorer, or open the photo you like the most in the photo app, or open a news reader, and click on “share” from there to show the system share capable apps. For sure you are going to find Multi social share there and only need to select it to start sharing your content. I didn’t think in Multi social share as a stand alone app. Is a social share target. Select some images, share them together and Multi social share takes care of upload everyone to onedrive, get a public url and short it using is.gd. you only need to write the text update, if you want, and click the share button.
Multi social share is priced at $1.29. As it is a universal app, if you buy one version you get both, no needs to pay twice for them. so each app cost you $0.645. Also you can use it totally free with the trial mode: no restrictions on time of use or number of shares. Only an ads banner and a little “using #multisocialshare” text append to your updates.
If you like to give a try to Multi social share, both on Windows 8.1 and Windows Phone 8.1, follow these links:

No it is not. That is not how SUBDOC works. As you have noted, subdoc entities are complete documents. I believe what you are refering to is applicational rendering issues. There are various way to dealing with rendering issues in a resonable manner. > Even if you leave them out a conforming SGML application would insert > them doing the omittag rules.

What needs to be addressed is how to render the subdocument. I wonder if CSS deals with the possibilites of subdocuments, or if it can be easily expanded to deal with subdocuments. Or we can try DSSSL. Or browsers can create their own hard-coded styles as they normally do ... > Using non-subdoc entities is a solution, but it raises the problem --------^^^^^^^^^^^^^^^^^^^ I.e.

If an author chooses to use entity references for parts of a document, and SGML editor (or an SGML parser) can perform validation to insure the entity will be valid where it is referenced. For simple header/footer capabilities, simple SGML text entities would suffice; subdoc may be overkill (and maybe not). > The W3C HTML DTDs already use parameter entities to simplify the > notation of content models.

Since subdoc is a complete document, the document can be published by itself without worry about what other documents may reference it as a subdocument (issues about the SGML declarations ignored for this discussion). Ie. I want the ability to reference an entire html document (ie. doctype = html) along with possible other documents of a different doctypes (eg: div, span, etc ...). For implemntors of WWW software, at least subdoc support can be done for HTML doctypes and doctypes that are subsets of HTML. This requirement should not be too difficult for major companies like Netscape and Miscrosoft. If not subdoc, at least general text entity support. --ewh (and still waiting for entity support) P.S. BTW, subdoc also guarantees separate name spaces. Hence, entities I define in the base document will not conflict with entities of the same name in the subdocument.

“Last but not least!” I stated after discovering the runic chains coming from the main they also have lastly show up, and then, I could truthfully provide the development I had waited for so long.
I had a good check out my sword before taking it in my hands and immediately believed the heaviness than it it experienced become even thicker, nevertheless it was a little something I really could keep with my energy. The sword noticed at ease during my hand and believed very well known there is not any uncomfortableness an individual might assume using the new designs.
My runes buzzed, plus they buzzed like they were thunder and published the vitality, which happens to be unlike any electricity I needed expert ahead of. It truly is multicolored with getting a pinkish many it and its thicker similar to a liquid, however it not and begin to leak in to the deepest part of me that even curse had not able to access.
The design of abomination is a lot more realistic if one investigated the style for more than a next, they could understand the abomination before these with many tentacles with a large number of mouths and vision about them.
It had taken a handful of moments to the runes to propagate into every side of my system and soul. They can be attained every corner, and also their denseness is much greater than my old runes, much more than seven times increased, the industry good deal.
It is actually still a greatsword with similar measurements, however right now it were built with a metal blade on what stunning silvery designs.

I became looking around my center when out of the blue, I noticed the ruble. The earth shook, and also the water raged well before I became thrown out of my primary.
The regress not alone has an effect on the sturdiness but also the possible of a single this is why it is also referred to as ‘slow poison,’ and lots of folks go mad and in some cases do suicide on account of extreme depressive disorders, as most individuals who sustained under it are gifted powerhouses who could not have this serious blow.
My runes buzzed, additionally they buzzed like these people were thunder and launched the power, which happens to be unlike any vitality I needed knowledgeable well before. It truly is multicolored with getting a pink majority of it and is also heavy similar to a liquid, nonetheless it not and initiate to drain into the deepest side of me that even curse experienced incapable of arrive at.
The Dark Magician Transmigrates After 66666 Years
I used with my sword for a time ahead of I looked over the unfamiliar s.h.i.+eld that is still inside the lake. The sophisticated mildew of my sword got cured all its cracks and nicks, though the s.h.i.+eld is a long way from recouping its aura remains to be weaker and would need a serious time ahead of it could be utilised.
I am just satisfied with the modern growth of my sword, together with time, it will turn out to be a lot more impressive. I possibly could truly feel how the energies with the core interacted using it, just in case it stayed here for a long time, it is going to have several positive improvements.
“Have a look at his expression he appeared to have gone angry knowing he is regressing,” Marla mentioned and as she viewed Micheal, who enjoyed a beaming smile on his deal with that had been finding nicer by a secondly.

I viewed my key from the outside and spotted hundred runic chains coming out of it. The runic chains presented different hues, but one that occupies one of the most is pink it really is acquired busy in excess of 50Per cent runes color variety.
I had taken a fantastic examine my sword before taking it inside my arms and immediately believed the heaviness of this it possessed turn into even more substantial, but it surely was anything I could possibly carry with my power. The sword observed secure within my hands and experienced very common there is not any uncomfortableness an individual might assume along with the new types.
I was exploring my center when suddenly, I observed the ruble. The planet shook, and also the ocean raged well before I had been dumped of my key.
It is additionally rapidly commencing to mend my consciousness and treat the soul that is certainly providing me a seriously pain. Sensation the pain rapidly lessening, I couldn’t support but be alleviated.
I got a very good evaluate my sword before taking it within my fingers and immediately noticed the heaviness of it it got turn out to be even more heavy, nonetheless it was some thing I was able to have with my energy. The sword sensed at ease in doing my fingers and observed very common there is not any uncomfortableness one particular might expect to have along with the new styles.
“Take a look at his expression he did actually have gone mad knowing he or she is regressing,” Marla reported so when she looked over Micheal, who enjoyed a beaming laugh on his face which has been finding richer from a 2nd.
You can find no alterations in the number of enchantments, although the three enchantments have altered substantially. I could not do many things with these that we was not able to do prior to.
I had a fantastic take a look at my sword prior to taking it inside my arms and immediately observed the heaviness of it it possessed grow to be even more heavy, but it really was anything I could possibly keep with my strength. The sword experienced relaxed around my hand and felt very common there is absolutely no uncomfortableness one might expect to have together with the new models.
Additionally, it is rapidly beginning to repair my consciousness and recover the heart and soul that is giving me a good discomfort. Experiencing the agony rapidly minimizing, I couldn’t help but be happy.
My aura, in lieu of growing, began to lower slowly and gradually. I had an aura of Maximum Top level, however right now it is slowly but surely regressing considering that large shiny teeth couldn’t assist but appear on my facial area. It happens to be developing the Inheritance is working as I had specially designed so that it is.
“I am hoping you should have a heart and soul sufficiently strong to deal with the poor poison,” He included using a sigh. He possessed observed quite a few qualified people today enduring the regress in the lifetime, and several of the judgements they required have been not only bad for themselves except for their world alone.
It needed several secs for that runes to distributed into every part of my system and soul. They may be attained every corner, as well as their solidity is significantly in excess of my classic runes, much more than seven instances significantly greater, which is a good deal.
It got several secs for your runes to pass on into every part of my entire body and spirit. These are reached every area, in addition to their density is way higher than my classic runes, a little more than seven days higher, that is a great deal.

LEARN CODING THROUGH MINECRAFT
TEACHING WITH COMPUTERCRAFTEDU
ComputerCraftEdu is designed to act as a low-threshold entry to learning programming. The emphasis is on direct and concrete outcomes: even the very first programs the player writes will result in functioning robots. With the help of a visual programming language designed to follow the Minecraft analogy, robots will feel natural part of the gameplay, bringing programming to the everyday life of the students.
The player progresses from giving easy directions to the turtle to writing their own programs in a visual programming environment and all the way to learning actual lua-code. The process of learning the syntax and moving to text-based programming is scaffolded by a unique integrated development environment that highlights the possible syntax choices for the player.
Much like Minecraft itself, ComputerCraftEdu promotes collaboration: students can easily share their programs with others and invite them over to help with programming by sharing their turtle.
Pseudo-programming in Minecraft
Players start by giving directions to the turtles using a simple remote view where they can control basic movement, digging and building one step at a time. They learn that robots need unambiguous instructions that are executed in a precise manner. Combined with materials outside the game, these activities teach the basics of designing algorithms without writing any programs yet. The ability to change the camera view to the turtle’s perspective scaffolds the process of perceiving the problems from different angles.
From single commands to a sequence
The remote view is still very limited in terms of functionality and only offers single commands. To write programs with more than one command players need to enter the program tab. In the program tab’s intuitive tile-based drag and drop programming they can start building more complex sequences. This also forces the players to think ahead: how many steps does it take to reach a wall or does my turtle need to dig up or down? As a teacher, you can encourage planning the programs in advance.
Syntax and repetition
The players move from the sequence of commands to automated algorithms with the help of integrated design environment, or an IDE-mode. After IDE-mode is toggled on, whenever a player drags a syntax-item (while, if, for) to the programming area, a list of possible next items opens under the tile. After selecting the next item, a new list of possible items appears, walking the player through the syntax of a loop/selection.
The rising need for improving learning STEM-subjects (Science, Technology, Engineering and Mathematics) has been recognized widely. Next Generation Science Standards were developed to answer this need. They don’t replace Common Core’s field of science literacy but supplement them. The NGSS lay out the disciplinary core ideas (DCIs), science and engineering practices that students should master in preparation for college and careers. ComputerCraftEdu is a great tool for STEM education, especially with Engineering Design DCI and below are a number of standards that align with it:
Next Generation Science Standards (NGSS)
ETS1- 1. Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
Comments: Designing programs in ComputerCraftEdu revolves around iterative design and direct, concrete feedback on the functionality of the program. Turtle robots are meant to be useful tools that help players solve problems and automate their regular Minecraft activities. The teacher's role is to ask the right questions and facilitate the players to find and test different solutions to problems.

I'm going to cut and paste this from the Dell message boards (Dell has no idea how to fix this.). I'm hoping someone here knows what the problem is.
Hi. I'm running a Dell Dimension 4300, running XP Pro, and ever since about a year ago, I've had erratic mouse behavior with whatever I've used. I've tried mice made by Microsoft, Logitech, the standard Dell mouse that the computer came with, and Kensington. I've tried each mouse (except the Dell one) with both USB connections, as well as with the USB=>PS/2 converter. With each mouse, I've tried both the default windows driver (HID-Compatible for USB, PS/2 compatible for PS/2 (mouclass.sys)), as well as the manufacturers' drivers (for example, Logitech's MouseWare), and I've tried each driver with each port. I've tried every known combination of mice, port, and driver available.
The following circumstances occur with all 4 brands of mice mentioned, all possible drivers, and all ports.
In each and every case, although with USB to a greater degree than PS/2, I've had erratic mouse behavior. When plugged into either the mouse port or the keyboard port, both PS/2 w/PS/2 converters, the mouse moves around fine for a bit, but every now and then (about once or twice a minute) it stops responding for a second or two, then goes on working fine again. I've noticed with games that when it stops working for a second, it keeps doing what it was doing; if I am firing an automatic weapon, it'll keep firing and I won't be able to stop it, but I won't be able to move with the mouse until it starts working a second later again.
When the mouse is plugged into a USB port, the same circumstances described above occur, but even more frequently, and the spells where the mouse stops working last even longer, sometimes up to 10 seconds.
I've even tried switching IRQ assignments in setup, updating my BIOS, uninstalling and reinstalling every known mouse driver to mankind... nothing.
I had completely formatted my hard drive a few months ago and ran a clean install of XP Pro, and for a while there, using the Logitech MX-500 with a PS/2 converter, for a few months it was running perfectly. But now the mouse problem has surfaced again, and I sure as heck haven't installed anything new in the past few days to make it just happen.
I've been reading this board and have read of many others with similar circumstances. I'm posting to let you, Dell, know, that this is a problem with every brand of mouse, every port, every driver. To me, it seems, the only other problem sources there could be would be Windows XP or my computer (my hardware) itself.
Please, for me and all of the others in this forum who have complained of erratic mouse behavior, find the cause of this and figure out a way to fix it, and let me know, okay?
And oh yeah, this applies to both optical and ball mice, and I've tried several colors of mousepad including black and red with the optical ones.
It's getting worse. If this helps, I've noticed that the problem increases during times of heavy load. Twice now, while trying to generate thumbnails for a folder with a lot of photos in it in XP, the mouse (Logitech MX500, have repeated the same effect plugged into both the PS/2 port w/ a converter and the USB port) has completely frozen and refused to start responding again until restart.
Mouse also freezes more often during gaming, video encoding, etc... than while just, say, surfing.
The worst freezes have been while loading the big thumbnail folders, which leads me to believe that large amounts of data transfer between ROM and RAM may be connected to the freezes, in which case the ultimate problem would lie either in the RAM, hard drive, BIOS, or motherboard. Since I haven't seen this problem with any other brand of computer quite like I have it, and I've seen many people complain about this problem with Dells, this would further support the hardware fault theory.
That's just what I think though, and I'm hardly a professional techie; just a user with above average computer knowledge. Take it for what it's worth.
The mouse problem is getting steadily worse though now as the days go on, and I'm anxiously awaiting a response from you, Dell. I've never had another problem with my computer in the two years that I've owned it, and if you can fix this for me I'll almost surely buy another Dell when this one becomes unbearably obsolete for usage.
I'm not quite sure I could say the same in a few years if this mouse thing isn't fixed, tho.
And oh, if it helps, with the optical mouse, when it freezes, the light still stays on in the mouse, meaning that the electrical connection still stays intact... it just stops responding.
Update: Just called Dell support... they led me through every step they had, all the way up to "Okay sir, the only step we have left is to reinstall the OS."
Considering these symptoms have occurred both before and after a clean format and install of XP Pro (was using Home before), I doubt that will do much, I tell him.
He says all he can do is forward the info to the techies and they'll email me when a solution is found.
Translation: Dell, it appears that you have no idea what is causing this problem with so many users, and even less of an idea as to how to fix it.
Naturally, unless a fix is at some point emailed to me like I requested with support, for some reason I have some doubt as to if I'll ever buy a Dell product again.

Basic CasparCG HTML template tutorial
The goal of this tutorial will be to create a new graphic template and converting it to HTML format compatible with CasparCG using Loopic. Our final graphic should look like the graphic on the next animation.
Final result of this tutorial is also available as a demo project on Loopic - you can load it by clicking on it in the Welcome popup.
There is also a video version of the tutorial available on YouTube.
Creating background elements
3 background elements will be created before adding text, and those are Shape elements. To create new shapes, click on the Plus button in the Timeline section and select Shape. Two shapes have just decorative purpose and the third one is there to serve as a background to our text which will be added.
You can easily resize and reposition shapes and change their background color.
As we are designing our lower third graphic with a white background, there is a problem - we can not see the white shape anymore because the composition background is white by default. This can be easily changed in the settings panel - pick any color of your choice.
Repositioning and renaming layers techniques are very simple in Loopic.
Importing a background image
It is always a good idea to add an example background image, just for design and development purposes. This way we can estimate the final look of the graphic once it is played on-air. In this tutorial, we will create a new Image layer and select our background image. Once it is imported, we will lock it by clicking the lock icon and setting the layer as a guide. To set the layer as a guide, right-click on it and choose Set as a guide. This is important because layers marked as guides will not be exported from the project. We will also change layer's order so that our guide is the last layer.
Adding Text elements
Adding Text elements is as simple as adding Shape elements. But key detail here is that our fields need to have unique ID names so we can identify them - in other words, we need to know what information to show in what text element.
We will name the name element as "title" and subtitle as "subtitle". Using underscore prefix is not required, however, it is recommended and it is the convention of naming text elements in CasparCG world.
Adding fonts is very simple in Loopic. All you need to do is click on the Plus button in the Fonts section of the Resources panel and select the fonts. Once imported, the fonts will appear in the fonts dropdown list. In this example, we used Exo 2 Regular and Exo 2 Bold fonts, so both fonts should be imported.
Saving the project
Since we have already done some nice work with Loopic, it is always recommended to save the project occasionally.
Here you are free to do anything you want - slide up, down, left, right, fade-in, cut, dance, fly… Whatever!
In the Timeline panel, click on the little arrow to open all available properties and start adding keyframes, moving them, deleting them.
We will try to animate white background shape to slide from the bottom to the top from frame 0 to frame 15. From frames 40 to 60, the shape will fade out.
Few more minutes of playing and here is our final animation.
Adding stop action
So far everything looks good, but how are we going to tell CasparCG when to stop the graphic and when to wait for the outro command? It is as simple as navigating to frame 40, which will be our "stop" keyframe, and clicking the "Stop & Outro" button. That's it!
For more information about actions, take a look at the dedicated tutorial just for actions.
Just the last step before we export our graphic - we must give a name to our composition. We will name it "lower-third" instead of "New composition" - sounds much better. This name will also be used as a name for our exported graphic.
And this is the best part of Loopic - exporting your composition as a graphic for CasparCG is as simple as clicking the "Export as CasparCG graphic" button! In a few moments, Loopic will generate a .html template with all the resources embedded directly in the HTML document, so you do not have to worry about copying images, installing fonts, and so on.
Playing with CasparCG
Now just move the file Loopic has exported to the CasparCG templates folder - or any other folder where CasparCG looks for templates. With any client application of your choice, you can now play the graphic by its name and send dynamic information to it by setting the template data keys to the IDs which we assigned to our text elements.
And that is it!
If you have any questions or problems, feel free to contact the Loopic team anytime. You can also reach us on social networks Facebook and Instagram - links are in the footer.

@E.P. lol, you can edit the post and add that in if you want, it's community wiki :)
@JayCarr naw, that's an old Chuck Norris one, the current list is too pristinely aviationy to soil it with something as mundane as exercise. Though on the other hand the no-hands pushup isn't as unrelated to aviation in the end?
Exercise? That's like a pilot's kryptonite!
make the impossible turn from any altitude is not a problem. Given enough airspeed, you can do it at any altitude.

At a GlanceWhile technologies like Flash, ThingMaker, and Shockwave, have made Web animation more interactive, fun, and even audible, GIF animation is still the tried and true standby for Web design due to factors such as accessibility and inexpensive/free tools. However, since file size -- and thus time -- is of the essence no matter which animation technology you use, the primary objective for Web designers using GIF animations is to deliver the animation using no more information than is absolutely necessary. For GIF animation, the key to this objective is optimization.
When GIF animations first leapt onto the Web scene, optimization was hardly an issue. The result was a flood of unoptmized and often poorly designed GIF animations. This created the false impression that GIF itself is strictly a low-quality animation option for the Web.
To be clear, "optimizing" an animation means that we are reducing its file size. The smaller the file size, the faster it will download. The goal is to make an animation's file size as small as possible while keeping it as presentable as possible. We will take a close look at the three GIF animation optimization techniques that are typically the most effective and then quickly talk about some of the other things that you can do to shave off a few extra bytes from your GIF animations.
The animated logo to the right is from the NavWorks Web site. We will use this 18-frame animation as the example animation for our discussion on optimizing GIF animations. While it provides valuable branding for the site, it is important that it doesn't take up too much bandwidth. This animation was created with GIF Movie Gear, a PC-based GIF animation program.
Reducing colors? Use a global palette
Typically, the more colors there are in an animation, the larger its file size. Due to how the GIF format compresses (using the LZW compression scheme), this is not always true, but this generalization holds true for the majority of GIF animations. It's important to understand that each frame in an animation can have a maximum of 256 colors. These colors must be stored with the GIF file in a palette. The more colors in a palette, the larger the files size.
Fortunately, you can use a single color palette for all of the frames in an animation. This is often referred to as a "global palette." Since palette information in a GIF animation is not compressed, an excellent way to optimize a GIF animation is to use a global palette for all the frames in the animation and to limit the number of colors in the global palette to as few colors as possible.
For example, the unoptimized size (at right) of the NavWorks animation is 47.5-Kbytes. Even though the NavWorks animation logo has not been optimized, it is slightly optimized because GIF Movie Gear converted all of the frames to a global palette when the frames were imported. If each frame had it's own 256 color palette the file size would be over 60-Kbytes. So, by using a global palette, the animation has already received a file size savings of over 12.7-Kbtyes.
Look carefully at the animation and you'll see that it's really composed of a few tones of gray and burgundy. So, 256 colors is probably too many colors for this animation. In fact, it looks fine at 32 colors. Reducing the animation from 256 colors to 32 colors reduces the file size down to just over 31-Kbytes -- a savings of over 16-Kbytes. When you add it up, the total savings is almost 30-Kbytes. By using a global palette and reducing the number of colors in that palette, I was almost able to reduce the file size of the animation in half.
"Dirty Rectangle" optimization
Dirty Rectangle optimization refers to a mode of optimization that involves cropping frames in a GIF animation to their smallest needed rectangle. These frames are then placed on top of each other using pixel coordinates for placement. The easiest way to understand this is to look at an example.
Look at the figure above. This shows each frame of the NavWorks logo after it has been optimized by the "Dirty Rectangle" method of optimization. Unneccessary or redundant portions of the frames have been cropped out. So, after the first frame, each frame is a smaller GIF file. The smaller GIF files are displayed over the first frame using pixels coordinates for their placement. Since the smaller GIF images only partially cover the first frame, you can still see parts of the original frame as the animation plays.
An animation optmized with the "Dirty Rectangle" method is really a collection of various sized GIF frames. The basic idea is that the smaller a GIF frame is, the less it adds to the overall size of the animation. By using the "Dirty Rectangle" method of optimization to create the NavWorks logo, I was able to reduce the animation's size from 31-Kbytes to just under 16-Kbytes. Again, nearly cutting the file size in half.
Interframe transparency optimization
Another way to optimize an animation is to make redundant portions of animation frames transparent. This often, but not always, results in file size savings. This is done by using two features in the GIF file format: transparency and disposal methods. Some colors in a GIF file can be made transparent, allowing the background image or color to show through them. The same is true for frames in an animation -- if parts of the frames are transparent, they show through to any other frames behind them. This is referred to as "Interframe Transparency" (some GIF animation utilities refer to it as "Frame Differencing").
Disposal Methods control how the browser will display frames of a GIF animation, and they determine how subsequent frames are displayed over previous frames. You will need the disposal method that allows transparent portions of GIF Animation frames to show through to earlier frames. GIF Animation utilities have different names for Disposal Methods, so you will have to check your animation utility for this feature.
The figure above shows the NavWorks logo animation after it has been optimized with Interframe Transparency. The bright green portions of each frame have been made transparent. This works visually when the animation is played because the GIF Animation utility has compared each frame, making any pixel transparent if it was the same color in the previous frame. This explains the term "frame differencing." Frames are compared with one another, making any redundant pixels transparent.
The Interframe Transparency optimization once again cut the animation's file size in half. With only color/palette reduction and "dirty rectangle" optimization the file size was 15.8-Kbytes. With interframe transparency optimization, the animation was reduced to 7.9-Kbytes. So, with all three of the GIF animation optimization techniques discussed, we have reduced the animation from 48-Kbytes down to just under 8-Kbytes -- and without damaging the visual quality of the animation at all as shown below.
Can you tell which image has been optimized, and which one hasn't? The unoptimized (48-Kbyte) image is on the left, and the optimized (7.9-Kbyte) animation is on the right.
Other optimization techniques
There are several other methods for optimizing GIF animations; some substantial, some minor. One technique often overlooked is that of removing frames. The fewer the frames in an animation, the smaller the file size. For example, when every other frame in the NavWorks logo is removed the resulting animation is only 6-Kbytes.
Another important way to keep your animations' size to a minimum is to crop them down to the smallest size possible. Similarly, some animations work just as well when they are smaller. Many animation utilities, such as GIF Movie Gear (for Windows) and GifBuilder (for the Mac), allow you to crop and resize animations. Finally be sure to turn off interlacing and GIF Comment blocks since both of those features tend to add a few unnecessary bytes to the filesize of a GIF animation.
All GIF animations are different and the LZW compression that the GIF format employs means that compression results can often be a bit unpredictable. However, once you master GIF animation optimization, you will be free to make more interesting animations without fear of them weighing down your Web pages. Also, for animations such as banner ads, smaller GIF animation file sizes will result in more views and a better overall impression of the ad. No matter how you look at it, taking the time to optimize GIF animations is usually well worth the extra effort.

Hello everybody, I am working on the design of a olive survey.
This was the structure (in summary) of the first desing and It works perfectly :
In one plot I can have 2 or more varieties.
But then some olive producers proposed me this other stucture:
They tell me that answer production data per general variety (not by variety on plot), is much easier and common for them .
So my problem is that I am not sure about if It is possible with the syntax build a summary (number of plants total and in production, efective area per variety) to introduce then the general production of the variety , and make some controls about production/plant or production/ha in the design.
All idea or advice will be welcome!!
How many varieties do you have to choose from?
Is it really 8 or is 8 just the tip of the iceberg?
I have 32 varieties and I have more questions in the sub-roster but those I mention are the most important for productions controls.
First, the recommendation that you are getting makes sense (and not just in the olive business). Many farmers can tell you info about each PLOT (such as area, irrigation status, etc) and what CROPS they grow there. But the harvest is largely put in a big barn, and from there is disposed of without any tracking where it is coming from. So the farmer will be able to tell for each crop (or variety) how much he sold vs. consumed in the household, but not by plot.
One final thought - such tree-search calculations may be somewhat heavy for some tablets. Definitely check the performance of your devices with a real-life example (not a trivial two-crops setup). As there is a risk that you can end up with something formally working, but not acceptable in practice.
Provided that the number of crops is not large (your 32 is ok) the fixed roster should be a proper solution for this task with a condition that the crop is mentioned on ANY of the plots. Your screenshot shows exactly that condition. And using the .Sum() function you should be able to estimate the total area under the crop to calculate the yield. (see examples here:
https://www.csharp-examples.net/linq-sum/ and in other internet resources).
Ok thanks for answer it.
About your comments:
"One final thought - such tree-search calculations may be somewhat heavy for some tablets"
Are you referring about the calculates that I want to do (sum of plants, area, etc from sub roster “Varieties” to “Production” list )?
2."Definitely check the performance of your devices with a real-life example"
Yes of course, our politic is always do lots of test before throw away the idea, so In this we are, but first I need to see if this is possible and works.
Finally, I understood that you think that It is possible:
3." And using the .Sum() function you should be able to estimate the total area under the crop to calculate the yield. "
Could It be for example, inside the “Production” list and the variety selected making new variables (fx) using some as example https://www.csharp-examples.net/linq-sum/?
Could you help me with the syntax? Sorry but I can`t see which of the examples are more convenient for this.
Could it be this one?:
In that case How could I do the adaptation? having as a example the summary or scheme that I sent in the first message.
var = ?
What are those above exactly doing reference ? I`m not sure.
@aortiz_dd, calculation of the average yield for multiple crops grown across multiple plots can be seen in the following public questionnaire: PUBLIC EXAMPLE - YIELD CALCULATION
An earlier discussion with @cboxho last month involved a different example with harvest reported separately for each plot-crop combination: PUBLIC EXAMPLE Crop Harvest
Ok thank you!
I could see PUBLIC EXAMPLE Crop Harvest ( and the earlier discussion) but I could not see PUBLIC EXAMPLE - YIELD CALCULATION, this last one where could I see It? You are talking about https://designer.mysurvey.solutions/questionnaire/public
Here is a direct link to the example questionnaire.
Thank you very much for your support!! the example questionnaire had the example that I needed.

[MM-17353] Wait for transition on RHS before rendering expensive sub components

Just took a look, and wonder if what I'm seeing is an issue: If the at-mention RHS is already open when change the screen width, the RHS can change from showing results to showing an endless loading indicator:
@lindalumitchell Yep that's definitely not ideal, I'll push up a fix.
@jasonblais I think we're okay, I've scoped this to only work with the search_results component so that it should only affect what it needs to, and resizes are handled (apart from the above issue). Not sure if anyone else has any cases worth testing before this goes in.

@amyblais can this going into v5.15?
Sure, is relatively non-risky?
Sure, is this relatively non-risky?
Relatively, the worst case scenario is the search results don't load on a certain view, but we've covered all cases. Just waiting for QA to suggest any additional cases to test before this goes in.
Thanks @devinbinnie, I've done some more testing on the new build of the test server, and found no issues. Some areas I tested, for reference:
Wide, mid (tablet), and narrow (mobile), and transitions between them for:

pinned posts when switching channels,
RHS expanded while transitioning
Removing QA Review label. Thanks!

this should be pretty well tested in the invalid events test here https://github.com/Gravity-Bridge/Gravity-Bridge/blob/main/orchestrator/test_runner/src/invalid_events.rs. It seems like this particular case was not properly handled and I'm working on a pr #10 to resolve the issue and get the bridge oracle moving again.
Hey there, I was the one who created the transaction. I guess the contract changed the format it expects the gravity address to be?
Yes it has, we now expect the address a bech32 encoded string rather than a bytes32 encoding of the address bytes. This facilitates our IBC forwarding feature where deposits to the bridge can be transparently forwarded to a destination chain.
Obviously only including the address bytes removes the extra metadata we need to figure out where to forward the transaction.
I need to both get some contract interaction docs up and ideally reach out to Etherscan so that we can register the contract properly. Since we launched with over 100 genesis validators the contract args are actually too long to register with them.
This issue has been resolved with the upgrade to gravity-bridge-2

Backing Up Your Cluster
Although your data might be protected by hardware RAID or host-based mirroring software and even possibly replicated to another site for disaster recovery purposes, you must have a consistent, usable backup of the data on your cluster. The requirement is twofold, involving backup of the root disk and backup of the application data. Both have their own specific challenges.
Root Disk Backup
Your root disk contains the Oracle Solaris OS with numerous configuration files that the system requires to perform its tasks. Not all of these files are static. Many of the log files you need to retain for auditing and debugging purposes are highly dynamic. Therefore, you must achieve a consistent backup of your system so that you can restore your system successfully, if the need arises.
When using UFS for the root disk, only two methods are available for achieving a guaranteed consistent backup of the root file system partitions:
- Boot the system into single-user mode.
- Use both lockfs and fssnap while the system is at its normal run level.
Obviously, booting a node into single-user mode requires that you switch over all the services hosted on this node. Not only does this result in service outages, but it also means that the application might have to share the resources on its new host node, which might degrade its performance somewhat. The lockfs/fssnap option seems better. However, they can result in the system pausing while the data is flushed from the buffer cache and a consistent view is reached. If this pause is too long, it might have an adverse effect on the cluster framework. Furthermore, any real-time process prevents fssnap from being able to lock the file system. Thus, with a Solaris Cluster installation, you must temporarily suspend the xntpd daemon. However, other processes, such as the Oracle 10g Real Application Clusters or Oracle 11g Real Application Clusters frameworks might make this approach unworkable.
After you have performed the backup, you can delete the snapshot and move on to the next partition on the root disk.
Example 4.12. Using lockfs and fssnap to Create a Consistent Root (/) File System Snapshot
Stop the xntpd daemon before locking the root (/) file system with the lockfs command.
# /etc/rc2.d/S74xntpd.cluster stop # lockfs -f
Take a snapshot of the root (/) file system using the fssnap command before restarting the xntpd daemon.
# time fssnap -o backing-store=/spare_disk / /dev/fssnap/0 real 0m19.370s user 0m0.003s sys 0m0.454s # /etc/rc2.d/S74xntpd.cluster start Perform backup... # fssnap -d /dev/fssnap/0 Deleted snapshot 0.
For an Oracle Solaris ZFS file system, the situation is much more straightforward. By issuing a zfs snapshot command, you can create a consistent view of a file system that you can back up and restore with confidence. Using the -r flag allows you to create these snapshots recursively for all file systems below a certain mount point, further simplifying the process.
Backing Up Application Data on a Cluster
The first challenge with backing up application data when a service resides on a cluster is determining which cluster node the service is currently running on. If a failure has recently occurred, then the service might not be running on its primary node. If you are running Oracle RAC, the database is probably running on multiple nodes simultaneously. In addition, the data might be stored on raw disk or in Oracle's Automatic Storage Management (ASM), rather than in a file system. Consequently, any backup process must be capable of communicating with the node that currently hosts the application, rather than depending on the application being on a particular node, and potentially using application-specific backup procedures or software.
Although fssnap can be used in certain circumstances to achieve a consistent view of the root (/) file system partitions for backup, do not use it with failover UFS file systems. The pause in file system activity while the snapshot is being taken might result in the service fault probe detecting a fault and causing a service failover. Furthermore, fssnap cannot be used with global file systems (see the section "The Cluster File System" in Chapter 2, "Oracle Solaris Cluster: Features and Architecture") because fssnap must be run on the UFS mount point directly and works closely with the in-memory data structures of UFS. This means that the PxFS client and server (master) must interpret the fssnap ioctl system calls, but this capability is not currently present in PxFS.
Once more, the Oracle Solaris ZFS snapshot feature enables you to obtain a consistent view of the application data and so is a simpler option if there are no specific tools for consistently backing up the application data.
Many backup products are available from Oracle and from third-party sources. Many have application-specific integration features, for example, the ability to integrate with Oracle's RMAN backup function. Most products can back up data stored in any file system (UFS, ZFS, QFS, VxFS) that you might have configured in your cluster.
Highly Available Backup Servers
It's obviously very important to perform regular, secure backups of your critical systems. This, in turn, means that the systems performing the backup must be sufficiently highly available. Otherwise, they might not be able to complete a backup within the time window available. Although there is little you can do to make an individual tape drive more available, you can have tape libraries housing multiple tape drives. Then the problem of availability rests with the system that controls the backups.
A backup (master) server contains the backup configuration information: catalogs of previous backups, schedules for subsequent backups, and target nodes to be backed up. Just like any other service, this collection of data files and the programs that access it can be made highly available. Thus, a highly available service can be achieved by placing the configuration files on a highly available file system, hosted by one or more Solaris Cluster nodes, and encapsulating the backup server program in a suitable resource in a resource group.
The most common data center backup configuration uses SAN-attached tape libraries with multiple tape drives. You configure the master server to manage the backup by communicating with the client software installed on each target cluster node to be backed up. Instead of defining an entire physical server as a target, you use the logical host of the individual services that require their data to be backed up. The master server then contacts the appropriate physical node when the time comes to back up the data. If you need to back up the individual nodes, then you define the backup so that it covers only the file systems that constitute the root (/) file system. When the time comes to perform the backup, the master server directs the client to stream the necessary dataset to one or more tapes in the library.
Solaris Cluster agents are available for both the StorageTek Enterprise Backup software and Veritas NetBackup. If a Solaris Cluster agent is not available for your backup software, you can easily create one, as described in the next section.

This is a purely speculative question. In the real world, IP addresses are allocated by a central authority, the Internet Assigned Numbers Authority. I wonder how the address space of IP or a similar protocol would be allocated in a free-market world. Or maybe the analogue to the internet in such a world wouldn't use such a protocol, but something completely different? I'd love to hear others' thoughts on this.
The keyboard is mightier than the gun.
Non parit potestas ipsius auctoritatem.
To add to this: Cato published a paper some years ago that presented a homesteading method for radio broadcasting. It consists of three elements: transmitter location, frequency range, and signal power. AFAIK, the Internet Protocol presents only one definite scarce resource, namely the global address space (in IPv4, 32 bits; in IPv6, 128 bits).
The basic building block of a dynamic network - such as the Internet - is the routing table. IP addresses basically permit each node in the network to answer the simple question "which way do I send this packet?" Think of postal mail. At each post office, the postmaster must determine whether his office is the final destination for each piece of mail or whether it has to be sent further on its way. Since he does not have a direct connection to every other post office, he must forward the piece of mail in the right direction, such as North, South, East or West, where it will be routed further. For example, if a piece of mail from LA arrives in the Boulder office, destined to New York City, the Boulder office may choose to send that piece of mail eastward to Philadelphia for further routing.
This is what Internet routers do and they use routing tables to automate the process. Whenever a packet arrives, the router will inspect the IP address of the packet and compare it to the routing table to determine which direction to forward the packet. From a propertarian perspective, it should be obvious that there is no need for a central authority at all, as all the owner of a router needs to do is subscribe to an IP-address lookup service - the equivalent of a privately-printed phone book.
The Internet as it is currently built is a bit of a death-trap. As is the case with roads, there is a false presumption among the Internet community that basic services - such as routing services and maintenance of IP-tables - was, is and always will be free... for no particular reason except it has always been this way. The problem with IP-address scarcity is a by-product of this tragedy of the commons, created by ICANN, the meddling of corporate giants, and doubtless the hidden hand of public agencies. Peer-to-peer services have long ago solve these problems without any need of central look-ups and issuing "authorities".
I was hoping you'd reply to this, Clayton, because I know you're a fellow computer guy. And you didn't disappoint.
You're absolutely right about routing tables. Are you suggesting basically something like DNS at the level of routing? That is, applying routing directly to human-readable names as opposed to numbers?
From what I understand, numbers have been used for IP addresses because they're more efficient for computers to work with. Human-readable names are "messy" by computer standards, as they don't necessarily have a fixed length (or, if they do, it has to be much longer than four bytes to be very meaningful). Then again, maybe it doesn't matter whether numbers are used under the hood, if the routing services are operated on a subscription basis. Certainly there could be multiple routing protocols used by multiple companies, and that would be largely or entirely transparent to the end consumers.
This is an interesting topic, and I don't have the knowledge to speculate here. I just wanted to say I hope you guys continue the discussion as I am very interested in what you guys have to say about it.
@Auto: All you need is a wide hash function... something that produces 128-bit or greater hashes... problem solved. The odds of hash-collision in the 128-bit region is calculated in one paper I read (Google "extendible hashing", look for the original IBM labs paper) to be 10-15, which is rarer than hardware failures. However, to be on the safe-side, we could easily bump that up to 256 bits with no appreciable loss of performance on modern systems and if I'm not mistaken, the probability of collision should then go to roughly 10-30, which is about 10 billion times less probable than two people choosing the same star in the visible universe at random (according to Wiki).
It sounds like such a wide function is essentially identical to a GUID implementation. At least theoretically, the probability of two 128-bit random numbers matching is 2^-128 or ~3*10^-39. The issue I have with such an identifying system is that it's entirely non-hierarchical. The vast majority of IP addresses are actually split between network prefixes and host identifiers. Per the notion of classless inter-domain routing, this split can exist anywhere within the 32 bits of an IPv4 address or the 128 bits of an IPv6 address. Routing tables use this hierarchical organization of the address space to make routing more efficient - instead of having to remember routes for every computer on the internet, they just have to remember routes for different (often large) groups of addresses. (You're probably familiar with all this already - I'm mainly explaining this stuff for people who might be reading.)
I do not believe that this is as difficult as it sounds. The reason is that although the internet is not owned, the cables, routers switches ect. are owned. It is these owners who would have to come to some sort of agreement on how to allocate domain names, IP addresses, etc. to satisfy their customers, namely the end users. Even without force, these organizations managing all of this would still have to work together as their consumers would demand it.
although the internet is not owned, the cables, routers switches ect. are owned.

This is for WebTrends newbies who are ready to try a custom report. We think, we hope, that WebTrends users who have hesitated to tackle this ultra-valuable feature will find it far easier than they thought. Often, the hesitation is simply due to terminology issues! We’ll go slow.
A “report” is simply a table just like you see everywhere in WebTrends’ results . It’s just rows and columns. The rows have labels and are a list of things, like a list of page URLs or referrers. The columns have labels and contain numbers that quantify the things in the rows, like number of visits or number of page views … per “thing” on the “list”.
Don’t read further until you have the above nicely fixed in your mental concept map. List of things … numbers for each thing on the list … the list of things goes down the side … the numbers for each thing go across.
- The “list of things” is called a “Dimension” in WebTrends. WebTrends has a lot of ready-made dimensions, plus you can easily make additional ones, called custom dimensions.
Examples of out-of-the-box dimensions: Page URLs and titles. Content Groups. Referring sites. Campaign names found in the WT.mc_id parameter. Visitor’s cookie value. Day of the week. New visitors and Return visitors. On-site search terms that appear in the parameter called WT.oss.
Examples of custom dimensions you can create: Product names as found in your site’s “productID=” parameter. Campaign names found in a parameter that has a name other than WT.mc_id. Product colors as found in your site’s “color=” parameter. On-site search keywords as found in a parameter called “searchterm” or something other than WT.oss.
- The columns containing numbers are called “Measures.” Again, WebTrends has a lot of them already made. In addition to the out-of-the-box ones, you can of course make additional ones..
Examples of out-of-the-box measures: Number of visits. Percent of total site visits. Number of views. Viewing time. Number of orders.
Examples of custom measures you can create: Number of instances of the parameter “color” having the value “purple.” Number of instances that contained the parameter “promocode=yes”.
Dimensions and Measures ARE in fact a basic custom report! You can add details like filters, but making a custom report is basically a matter of combining a dimension with one or more measures.
Making a custom report in WebTrends goes something like this, once you have opened the Custom Reports >> Reports >> New Custom Report screen:
- You choose a dimension.
- You choose at least one measure.
- You give the report a name and save it into the custom report pool.
- You attach it to a profile.
- You make sure the template will allow the report to be displayed.
- You analyze some data.
- You look at the data.
- If you don’t like the custom report you modify it or you can un-attach it from the profile and delete it from the pool of custom reports.
That’s the basic structure, but it’s of course not the whole story. Here are the two other essential things:
- Use filters to make a custom report that shows data only for a subgroup of your overall data. For example, you may want the custom report to display data only for first-time visitors, or visits from Google, or visits that included a purchase.
Examples of out-of-the-box filters: Day of the week is Sunday. Entry page is URL “xxxx.” Visitors are Returning. Campaign ID (from WT.mc_id) is “zzzzz.” Visits that did NOT arrive from a search engine.
Examples of custom filters you can make: Product page views where the product has the color parameter “purple” or “blue.” Visits that contained at least one product page view where the product has the color parameter “purple” or “blue”. Pages classified as error pages. Visits that arrived through search terms that contained your company’s name. On-site search terms that returned no results, i.e. that had a value of zero for the parameter than shows number of search results returned.
Using more than one dimension at a time
- If you want, you can nest one dimension inside another, in a so-called 2-dimension Custom Report. For example, you can nest the “Page URLs Viewed” dimension inside the “New vs Return Visitor” dimension. The result would be a list of all the Page URLs Viewed by New visitors, followed by another list of Page URLs Viewed, this time by Return visitors. All in the same report. The “outside” dimension (New vs Return in this example) is called the Primary dimension and the inner nested dimension is called the Secondary dimension and the whole thing is a Two-Dimension Report. By the way, when you’re ready, The WebTrends Outsider has a post with more details about the ins and outs of 2D custom reports.
- You can take the concept further and have a drill-down report, which is the nesting of three or more dimensions. This is a little more complicated to do than 2D reports, but not that much more.
Finally, there are some smaller details that you don’t have to worry about until you’re fairly comfortable making custom reports:
- If you want your report to show a trend graph (over time) for a particular measure you have to tell WebTrends to do so, by checking the “use interval data” box. Otherwise WebTrends will conserve database space by not storing the day-by-day info necessary for a trend graph.
- If you have a trend graph, the first measure will be the one graphed in the default view. Keep this in mind as you are adding your measures.
- Check the box “Exclude activity without dimension data” if you don’t want a “None” row in your data for hits/visits that don’t fit the dimension. We recommend not checking this box while you test your report, because the “None” row can help with troubleshooting.
- If you use both Include and Exclude filters, remember that Exclude filters trump Include ones.
Having covered the basic concepts and structure of a custom report and hoping you’ll just want to jump in and feel your way through the setup of one, we want to add this:
The hard part of custom reports is deciding what should be the dimension and filtering. Really. It is not always easy to translate some vague “I wanna know …” question into specifics of dimensions and filters. If this stumps you, don’t be discouraged. You will get better at it as your mind wraps itself around this way of thinking.
To get examples of some custom reports that have been explicitly described here in the Outsider, go to the Cool Custom Reports category. A few of them are a little high-level but you’ll see custom report logic in action.

EiffelStudio 6.8, released last month, contains the first official implementation of the SCOOP programming model for concurrent programming. This is an important milestone; let me try to explain why.
Concurrency challenging us
Concurrency is the principal stumbling block in the progress of programming. Do not take just my word for it:
- Intel: “Multi-core processing is taking the industry on a fast-moving and exciting ride into profoundly new territory. The defining paradigm in computing performance has shifted inexorably from raw clock speed to parallel operations and energy efficiency” .
- Rick Rashid (head of Microsoft Research): “Multicore processors represent one of the largest technology transitions in the computing industry today, with deep implications for how we develop software.” .
- Bill Gates: “Multicore: This is the one which will have the biggest impact on us. We have never had a problem to solve like this. A breakthrough is needed in how applications are done on multicore devices.”
- David Patterson: “Industry has basically thrown a Hail Mary. The whole industry is betting on parallel computing. They’ve thrown it, but the big problem is catching it.”
- Gordon Bell: “I’m skeptical until I see something that gives me some hope… the machines are here and we haven’t got it right.” .
What has happened? Concurrency used to be a highly specialized domain of interest to a small minority of programmers building operating systems and networking systems and database engines. Just about everyone else could live comfortably pretending that the world was sequential. And then suddenly we all need to be aware of concurrency. The principal reason is the end of Moore’s law as we know it .
This chart show that we can no longer rely on the automatic and regular improvement to our programs’ performance, roughly by a factor of two every two years, thanks to faster chips. The free lunch is over; continued performance increases require taking advantage of concurrency, in particular through multithreading.
Performance is not the only reason for getting into concurrency. Another one is user convenience: ever since the first browser showed that one could write an email and load a Web page in the same window, users have been clamoring for multithreaded applications. Yet another source of concurrency requirements is the need to produce Internet and Web applications.
How do programmers write these applications? The almost universal answer relies on threading mechanisms, typically offered through some combination of language and library mechanisms: Java Threads, .NET threading, POSIX threads, EiffelThreads. The underlying techniques are semaphores and mutexes: nineteen-sixties vintage concepts, rife with risks of data races (access conflicts to a variable or resource, leading to crashes or incorrect computations) and deadlocks (where the system hangs). These risks are worse than the classical bugs of sequential programs because they are very difficult to detect through testing.
Ways to tame the beast
Because the need is so critical, the race is on — a “frantic” race in the words of a memorable New York Times article by John Markoff — to devise a modern programming framework that will bring concurrent programming under control. SCOOP is a contender in this battle. In this post and the next I will try to explain why we think it is exactly what the world needs to tame concurrency.
The usual view, from which SCOOP departs, is that concurrent programming is intrinsically hard and requires a fundamental change in the way programmers think. Indeed some of the other approaches that have attracted attention imply radical departures from accepted programming paradigm:
- Concurrency calculi such as CSP [6, 7], CCS and the π-Calculus define high-level mathematical frameworks addressing concurrency, but they are very far from the practical concerns of programmers. An even more serious problem is that they focus on only some aspects of programming, but being concurrent is only one property of a program, among many others (needing a database, relying on graphical user interface, using certain data structures, perform certain computations…). We need mechanisms that integrate concurrency with all the other mechanisms that a program uses.
- Functional programming languages have also offered interesting idioms for concurrency, taking advantage of the non-imperative nature of functional programming. Advocacy papers have argued for Haskell [10 and Erlang in this role. But should the world renounce other advances of modern software engineering, in particular object-oriented programming, for the sake of these mechanisms? Few people are prepared to take that step, and (as I have discussed in a detailed article ) the advantages of functional programming are counter-balanced by the superiority of the object-oriented model in its support for the modular construction of realistic systems.
What if we did not have to throw away everything and relearn programming from the ground up for concurrency? What if we could retain the benefits of five decades of software progress, as crystallized in modern object-oriented programming? This is the conjecture behind SCOOP: that we can benefit from all the techniques we have learned to make our software reliable, extendible and reusable, and add concurrency to the picture in an incremental way.
From sequential to concurrent
A detailed presentation of SCOOP will be for next Monday, but let me give you a hint and I hope whet your appetite by describing how to move a typical example from sequential to concurrent. Here is a routine for transferring money between two accounts:
transfer (amount: INTEGER ; source, target: ACCOUNT)
-- Transfer amount dollars from source to target.
enough: source·balance >= amount
removed: source·balance = old source·balance – amount
added: target·balance = old target·balance + amount
The caller must satisfy the precondition, requiring the source account to have enough money to withdraw the requested amount; the postcondition states that the source account will then be debited, and the target account credited, by that amount.
Now assume that we naïvely apply this routine in a concurrent context, with concurrent calls
if acc1·balance >= 100 then transfer (acc1, acc2, 100) end
if acc1·balance >= 100 then transfer (acc1, acc3, 100) end
If the original balance on acc1 is 100, it would be perfectly possible in the absence of a proper concurrency mechanism that both calls, as they reach the test acc1·balance >= 100, find the property to be true and proceed to do the transfer — but incorrectly since they cannot both happen without bringing the balance of acc1 below zero, a situation that the precondition of transfer and the tests were precisely designed to rule out. This is the classic data race. To avoid it in the traditional approaches, you need complicated and error-prone applications of semaphores or conditional critical regions (the latter with their “wait-and-signal” mechanism, just as clumsy and low-level as the operations on semaphores).
In SCOOP, such data races, and data races of any other kind, cannot occur. If the various objects involved are to run in separate threads of control, the declaration of the routine will be of the form
transfer (amount: INTEGER ; source, target: separate ACCOUNT)
-- The rest of the routine exactly as before.
where separate is the only specific language keyword of SCOOP. This addition of the separate marker does the trick. will result in the following behavior:
- Every call to transfer is guaranteed exclusive access to both separate arguments (the two accounts).
- This simultaneous reservation of multiple objects (a particularly tricky task when programmers must take care of it through their own programs, as they must in traditional approaches) is automatically guaranteed by the SCOOP scheduler. The calls wait as needed.
- As a consequence, the conditional instructions (if … then… ) are no longer needed. Just call transfer and rely on SCOOP to do the synchronization and guarantee correctness.
- As part of this correctness guarantee, the calls may have to wait until the preconditions hold, in other words until there is enough money on the account.
This is the desired behavior in the transition from sequential to concurrent. It is achieved here not by peppering the code with low-level concurrent operations, not by moving to a completely different programming scheme, but by simply declaring which objects are “separate” (potentially running elsewhere.
The idea of SCOOP is indeed that we reuse all that we have come to enjoy in modern object-oriented programming, and simply declare what needs to be parallel, expecting things to work (“principle of least surprise”).
This is not how most of the world sees concurrency. It’s supposed to be hard. Indeed it is; very hard, in fact. But the view of the people who built SCOOP is that as much of the difficulty should be for the implementers. Hence the title of this article: for programmers, concurrency should be easy. And we think SCOOP demonstrates that it can be.
SCOOP in practice
A few words of caution: we are not saying that SCOOP as provided in EiffelStudio 6.8 is the last word. (Otherwise it would be called 7.0.) In fact, precisely because implementation is very hard, a number of details are still not properly handled; for example, as discussed in recent exchanges on the EiffelStudio user group , just printing out the contents of a separate string is non-trivial. We are working to provide all the machinery that will make everything work well, the ambitious goals and the practical details. But the basics of the mechanism are there, with a solid implementation designed to scale properly for large applications and in distributed settings.
In next week’s article I will describe in a bit more detail what makes up the SCOOP mechanisms. To get a preview, you are welcome to look at the documentation [14, 15]; I hope it will convince you that despite what everyone else says concurrent programming can be easy.

You might have a lot to say, but you don’t want to overwhelm the readers of your blog. It’s a good idea to break up your posts into several shorter ones. That way, people don’t have to scroll through an intimidating 10,000-word post. Sequences help with that. Write several blog posts and link them up so that people can follow the path.
I’ve posted many blog posts that belong in sequences. Some of them are presentations and transcripts that I’ve spread out across time to make it easier for people to digest. Some of them are blog posts that I’ve organized after realizing how they’re related. I used to link these posts by hand, updating each post with a link to the next one and linking each new post with the one before it. Creating one page that listed all the posts meant yet another page to keep up to date. It took time to set up these links, and I didn’t always remember to do so.
When I look at my website analytics, I find that most of the visits are to pages that are deep within my archive. Besides the suggestions from Similar Posts, I also want to give people clearer paths through the content. That way, they can learn on their own. I wanted to make it easier to manage those trails through my blog posts without needing to edit many pages.
Organize Series is a WordPress plugin for sequences of posts. I like the way you can adjust the order of posts in the sequence. I customized Organize Series so that it didn’t show the list of posts at the beginning of each post, but I kept the other defaults. Organize Series adds links to the next and previous post, and it also adds a link to a page with all the posts in the series. I like the way that Organize Series makes it easy for readers to see many posts on the same page.
To see Organize Series in action, check out the series for A Visual Guide to Emacs. It links together three of the sketches I’ve made. I can add more posts as I publish them. You can also see the previous and next links in a post that belongs to a series, like this one for Adding Color, the second lesson in this Sketchnote Lessons series. Check out the rest of my series too.
The Organize Series plugin is free, and there are commercial add-ons. I haven’t bought one yet, although I find a few of them tempting. In the meantime, I’m looking forward to adding more series as I make my archive easier for people to use. Hope this helps!
- If you have a self-hosted WordPress blog and you write sequences of blog posts, give Organize Series a try.
- Curious about what I’m learning? Suggest some sequences for me to organize or write about!

In November of 2019 Greg Mills and I pulled off an incredible trip. We flew to the Inupiaq village of Selawik, then ice skated 125 miles to Kotzebue. Our route crossed the Arctic Circle three times, and we skated ~95 miles in the first 1.5 days.
This kind of trip just isn’t possible without relying on today’s remote sensing and other high-tech tools. I used all the tools in my toolbox– Google Earth, windy.com, Gaia GPS, and remote sensing resources. You should review my Remote Sensing tutorials before trying to make sense of the transfer process discussed here.
Sentinel Hub Playground and Sentinel Hub EO Browser are powerful resources for exploring near-real time satellite imagery, but the applications don’t support drawing waypoints or routes over the imagery. Fortunately, we can save georeferenced images from EO Browser, and work with them in in Google Earth or QGIS, producing a kml file that can be loaded into Gaia GPS.
Create a (free) account with Sentinel Hub EO Browser, sign in. Pull up your layer of interest, at a relevant zoom level. What you see on the screen is what you will download. Click on the “Download image” icon from the options on the far right.
The “Basic” tab allows quick download of non-georeferenced images. Click on the “Analytical” tab to work with georeferenced images.
“Analytical” download options
- JPG or PNG: Not georeferenced
- KMZ/JPG (smaller file) or KMZ/PNG (larger file): For use in Google Earth
- Tiff: For use in Avenza (?), QGIS or other GIS applications
Choose an appropriate resolution for your needs. I’ve been using the default 3857 coordinate system.
Avenza Maps is a Gaia GPS rival that allows you to load custom maps, any georeferenced image, for navigation offline. You can load three maps before having to upgrade to a paid account. Use an online converter to convert your Tiff to a GeoPDF, then load the GeoPDF into Avenza.
Sentinel georeferenced image in Avenza Maps
The easiest option to work with EO Browser files is in Google Earth. Save as KMZ/JPG or KMZ/PNG (the smaller jpg works fine for me) and open in Google Earth (desktop or browser). Once in Google Earth, you can trace polygons or drop waypoints based on the image layer, then export those features to your phone or GPS like any other kml/kmz. Refer to 3D Route-Planning: Google Earth for tutorials on how to use Google Earth.
QGIS is open-source GIS software, a free ~equivalent of ESRI’s ArcGIS. Working with QGIS is not as easy as Google Earth. I’m including it here in case you have a georeferenced image that is not compatible with Google Earth.
Save the EO Browser image as a Tiff. I assume the 8-bit option is fine four our needs. Drag the saved file into QGIS, it should load automatically.
You want a basemap to make sense of where the satellite image is located in the world. Load the QuickMapServices plugin to have access to many basemaps.
(Menu bar) Plugins –> Manage and Install Plugins –> QuickMapServices –> Install
Menu bar Web –> QuickMapServices –> select a basemap. I like OSM Standard and ESRI Satellite.
Note… to view the full list of the options, choose “Settings” from the bottom of the list, click the “More services” tab, and select “Get contributed pack.”
If you select multiple basemaps, you will only see the top layer. Arrange layers in the “Layers” panel, lower left quadrant of QGIS.
To add waypoints, lines, or polygons, you need to create a shapefile for each feature type. You can’t create a shapefile with mixed feature types. Click on the “New Shapefile Layer” button from the toolbar (or Layer –> Create Layer –> New Shapefile Layer from the menu bar), then select the appropriate Geometry type. I’m going to draw Polygons in this demo. Click “Ok”.
QGIS edit controls
The new shapefile should appear in the Layers panel. Select it, then press the pencil icon to edit. In edit mode, click on the green polygon icon to draw polygons (if you are drawing points or lines, you will have different green shapes instead of the polygon). Finish each polygon by right-clicking, and assign an integer id (“1”). You can draw as many polygons as you want within the single shapefile.
Double-click on the layer item to play with styling, though the styling won’t persist to your exported file. To export the shapefile, right-click on the layer in the layer list, select Export –> Save Feature as…
For use in Google Earth and Gaia GPS, export as KML. The KML file can be loaded directly into Google Earth or Gaia GPS.
Sentinel WMS tiles in QGIS
For folks that want to dive deeper… you can load Sentinel’s tiles directly into QGIS.
Open Developer Tools in your browser and reload the Sentinel EO Browser site with your layer of interest already selected. In Developer Tools, select Network and filter the results with the text “wms.” Right-click on any satellite tile (you can see the previewed tile), select Copy –> Copy Link Address. Open the link in a text editor and remove everything after the question mark (including the question mark).
In QGIS, right-click on “WMS/WMTS” in the Browser pane (upper left) –> New Connection. Give the connection a name and post your truncated url in the “URL” field. You should see your new connection as an option, navigate down to the specific layer you want to visualize.
Note that this process only gives you access to that day’s imagery. You can’t use this process to browse other dates.
Refer to Navigation with Gaia GPS for a tutorial on importing kml files.
Gaia is actively working on functionality that will allow users to upload georeferenced images. This will allow us to view the actually satellite image, not just the traced features. I can’t wait!

I have donated about 6 times before in my life -- I've been rejected a couple of times, either due to low iron or once due to the fact that I had visited an area in Mexico that was considered a Malaria risk.
My husband didn't want me to donate. He was worried that it would sap my energy. (He can't give blood because the sight of his own blood causes him to pass out.) However, I feel pretty strongly that right now is an important time to give blood if I can. Patients from hospitals in the hurricane's path have been relocated here and to Austin, and the blood banks in the lower-lying areas will also be closed due to the evacuations. With the high winds (110+ mph) expected, it's sad to say but I think there will be serious injuries due to flying debris.
Well, I am happy to say that I met all of the qualifications -- had enough iron, good blood pressure, enough time had passed since my Mexico vacation. They had some questions about my medications, but nothing I was on (Provigil, Effexor, Xyrem, or my contraceptive injections) precluded me from donating.
The actual donation went fine. I stayed afterward and drank water, gatorade, and ate a granola bar. I was able to run a couple of other errands that I needed to on the way home. BUT.. my husband was right. Since I got home, I have been really exhausted. He called me a couple of times from work and said I was "loopy." Now.. I don't feel LOOPY, but I do feel tired. I took one more nap than usual. I'm trying to drink as much water as I can and to keep my electrolytes in balance, but I am just pooped.
Just wanted to share this with all of you. Not sure if any of you have had similar experiences. I would not want to discourage anyone from giving blood -- especially in a time like this. But I know that in the future I'm going to have to plan a day to recover the next time I give.
Posted 12 September 2008 - 09:50 PM
It's totally great that you do this. Especially this time of year they are really needing it not just because of the hurricanes, but in general. My appointment is not till next week. They started sending me cards about two weeks ago. being O negative, that makes me universal or something. I go every fall except the last two years. (because I donated to myself over the summers for a couple of surgeries.) I think that anyone who can do this should.
I know that when I go I always have a ride home. I usually dont do to well. I'm not afraid of needles or anything but it really seriously drains me. I get all woozy and such. I end up sleeping a whole lot and dont plan anything for that day or the next day either just in case. It never occurred to me that Having narcolepsy could affect how I recover from this. lol... I just assumed everyone felt like crap after! Maybe I should pay more attention to how I eat before and after this. They deffinately have great cookies down there, but I guess that is not enough! Since I dont eat meat that probably does not help either. I never really thought about any of this before so Thankd Kimberly for bringing it up. I should look into being better prepared... then I will let you know how it goes....

Best metric to assess similarity between flight trajectories features
Consider a flight as represented by a dataframe with spatial (latitude, longitude, altitude) and temporal (timestamp) coordinates. Along the flight I have a variable tracking the length of the previous segment spent in some specific condition (e.g. temperature above a certain threshold), accumulatedMilesWithCondition:
latitude
longitude
timestamp
altitude
accumulatedMilesWithCondition

DESTINATION
I simulated the same flight (same departure, destination, start time) with slightly different conditions, which leads to dataframes having slightly different spatial (besides from departure and destination, obviously) and temporal coordinates.
I want to derive a metric that would give me an estimation of how "similar" the variable accumulatedMilesWithCondition is between different flights. For example, here I'm comparing 3 different versions of the same flight using a color mapping that highlights the areas where accumulatedMilesWithCondition is increasing (that is, the areas where my condition is satisfied).
The idea would be to have a metric that gives a more quantitative idea on how these "images" are visually similar.
I've been experimenting with various metrics but the problem is that in all these cases I always need to somehow resample to a common index and this is hard to do because the only invariant of these flights is the departure and destination coordinates, while the rest can evolve freely (although, as I said, usually differences are really small). This means that also the number of points for some flights may be different.
Do you have some ideas regarding strategies to compare characteristics of different flight trajectories?
I think a variational autoencoder (VAE) with a 1D convolutional encoding stage might work.
The 1D convolutional encoding stage would be able to encode trajectory data that is long, multivariate, and of variable length.
Situating this in a VAE architecture would mean the network learns a representation of samples such that similar samples would be situated close together in that space.
This is just like dimensionality reduction, where you can project data into a 2D space and find that related samples cluster together. The complexity for this particular task arises from the data's structure, where we need to handle the variable sequence lengths amongst other things.
Suppose you train such a net, and then want to measure the similarity of two new trajectories. You'd pass them both through the encoder and read off their encodings. You can then compute the distance between the encodings (a scalar $d\ge0$), and interpret it as a dissimilarity measure.

The git reset command is primarily used to undo things, as you can possibly tell by the verb. It moves around the HEAD pointer and optionally changes the index or staging area and can also optionally change the working directory if you use --hard.This final option makes it possible for this command to lose your work if used incorrectly, so make sure you understand it before using it. 2017-09-12

staging helps when a merge has conflicts - When a merge happens, changes that merge cleanly are updated both in the staging area as well as in your work tree. Only changes that did not merge cleanly (i.e., caused a conflict) will show up when you do a git diff, or in the top left pane of git gui.

How to lose your job like a pro: 1. Set my LinkedIn profile to “Open to Work”. (To get contacted by recruiters) 2. LinkedIn automatically generated a public post for me to inform everybody (without my knowledge) 3. my manager just liked the post. 4. Now I have an awkward meeting to attend Monday morning AMA 🤦♂️
Working for the toxic Deloitte environment was really traumatic for me and many of my colleagues. It took a long time to get over that weekly Sunday depression that kicked in from me dreading having to go back into the office on Mondays. As part of the great resignation class of 2020, I salute those who jumped from that chaotic environment and into industry roles while living their wildest professional dreams. For all those looking to join Deloitte as a potential employer, look elsewhere.

I can't find <dynamic_reconfigure/server.h> in the dynamic_reconfigure package
Hi all,
I'm learning ROS using the tutorial section. Right now I'm doing this one: http://wiki.ros.org/dynamic_reconfigure/Tutorials/SettingUpDynamicReconfigureForANode%28cpp%29.
I understand that dynamic_reconfigure is the package with the tools I need to use, but I can't find this server.h header. I did
rospack find dynamic_reconfigure
and the path is: /opt/ros/melodic/share/dynamic_reconfigure. Then, if I do:
ls /opt/ros/melodic/share/dynamic_reconfigure
I get: cmake msg package.xml srv templates. No sign of server.h ! I've already built and run the node, as the tutorial suggested, and it seems to work. For example, I can find dynamic_tutorials/TutorialsConfig.h in devel/include/dynamic_tutorials.
What am I missing?

Hi @alberto, can you please post the exact error displayed.
Comment by alberto on 2022-01-12:
Hi @osilva, I don't have any error. I'm new to ROS, and I want to understand this thing: since the tutorial says:
#include <dynamic_reconfigure/server.h>
I expect to go in the dynamic_reconfigure directory and to find the server.h file, but there isn't any server.h in there. So how can this include work without error? Where is this server.h file? Maybe it's just a dumb question, but I can't find the answer..
Comment by osilva on 2022-01-12:
Hi @alberto, it's part of dynamic_reconfigure package, check this link that shows the source code for location of server.h
Comment by osilva on 2022-01-12:
A definitely not a dumb question. It takes time to get used to how the packages work.
Hi @alberto
You may find the server.h file in this folder:
opt\ros\melodic\include\dynamic_reconfigure
Also you can see the source code here for location of server.h

Comment by gvdhoorn on 2022-01-13:
This answer would be improved if it explained the general layout of the /opt/ros FHS prefix. See REP 122: Filesystem Hierarchy Standard layout changes for ROS for information.
Headers are never present in /opt/ros/$ROS_VERSION/share. Only in /opt/ros/$ROS_VERSION/include.
Comment by alberto on 2022-01-13:
Thank you both!
Now I understand, using rospack find I get the path with ../share/.. and it's correct, in fact reading @gvdhoorn link, it says that: All architecture-independent package-relative assets are explicitly installed to share/ros-package-name. But all the headers are installed in the include directory. In fact searching the ../include/.. I find the server.h. Thank you again!
Comment by osilva on 2022-01-13:
Glad it worked out @alberto. And @gvdhoorn thank for adding the additional information and taking time to improve the answer.

Two tropical cyclones made landfall in Australia just hours apart. Cyclone Monty came ashore along the northwest coast of Western Australia on the evening of March 1, 2004, (local standard time) while Cyclone Evan made landfall a few hours later in the early morning hours of March 2nd along the east coast of the Northern Territory. Monty formed into a tropical depression on February 26 from an area of low pressure that moved off of the coast of Western Australia into the Indian Ocean. The depression strengthened into a tropical storm early on February 27 and continued heading westward parallel to the coastline. It also continued to intensify. By 10 pm, Western Australia time (12:00 UTC) on the 29th, Monty had become a powerful cyclone with sustained winds estimated at 125 miles per hour (200 kilometers per hour). It was rated as a Category 4 Cyclone by the Bureau of Meteorology’s Tropical Cyclone Warning Center in Perth. An advancing cold front coming up from the southwest then steered Monty back towards the coastline, towards the southeast, where it then came ashore as a strong Category 3 storm near the town of Mardie.
Meanwhile, Cyclone Evan formed in the Gulf of Carpentaria becoming a depression on February 29. Evan also moved westward but did not become nearly as strong, achieving Category 1 status at 7 pm Australia North time (9:30 UTC) on March 1 just before crossing the island of Groote Eylandt. Evan hit the mainland on the east coast of the Northern Territory early the next morning while still a Category 1 storm according to the Tropical Cyclone Cyclone Warning Center in Darwin.
The Tropical Rainfall Measuring Mission (TRMM) satellite captured several unique images of these two cyclones. The image on the left shows Cyclone Monty off of the coast of Western Australia, north of Barrow Island. The image was taken at 11:31 pm Western Australia time (15:31 UTC) on February 29, 2004. At the time, Monty was a powerful Category 4 cyclone. The image shows the horizontal distribution of rain rates as seen from overhead by the TRMM satellite. Rain rates in the center swath are from the TRMM Precipitation Radar (PR), the first precipitation radar in space, while rain rates in the outer swath are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on infrared (IR) data from the TRMM Visible Infrared Scanner (VIRS). Monty’ center falls within the TMI swath in this image, and the TMI does not have as fine a resolution as the Precipitation Radar. However, the TMI does show some heavy rainfall (red area) on the northwest side of the eye. Tropical cyclones rely on the heat that is released when water vapor condenses into cloud droplets to drive their circulation. These smaller droplets eventually form into larger raindrops that are easier to observe.
The next image of Monty (click on link marked Cyclone Monty, March 1), taken at 10:35 pm, Western Australia Time (14:35 UTC) on March 1, captures the storm just as it was hitting the coast. The image also shows rainrates overlaid on IR data as before, only now the PR passes directly over the center of the storm. TRMM shows that Monty still has a tight, well-organized circulation with a closed eye still visible and good banding surrounding the center. These bands are evident in the green areas associated with moderate rainrates. TRMM reveals that the bulk of the heavier rainfall (green areas) is on the left hand side of the storm as it is making landfall.
TRMM also captured a remarkable image (right) of Cyclone Evan just as it was entering Dalumbu Bay before crossing Groote Eylandt. This image was taken at 2:20 pm, Northern Australia/Darwin Time (04:50 UTC) on March 1. An area of intense rainfall (darker reds) appear near Evan’s center, but the tight banding seen in Monty is not apparent. Even though this region of intense rainfall could fuel the storm, Evan is too close to land for it to have a chance to intensify. As it crossed Groote Eylandt on March 2, the storm dumped a record 316 millimeters (12 inches) of rain on the island. The island’s previous 24-hour rainfall record was 158 millimeters (6 inches).
The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center monitors rainfall over the global tropics. The linked titled "Rainfall Totals" shows MPA rainfall totals for northern Australia in association with these two cyclones from February 23 to March 1, 2004. A swath of heavy rainfall (red areas) on the order of 8 to 12 inches is observed mainly offshore in association with Monty though some heavy and moderate (green areas) totals are evident over the coast. The rain associated with Evan, however, is embedded within a broad area of moderate (green areas) rainfall with locally heavier amounts (red areas) covering the Gulf of Carpentaria, the Northern Territory, and northern Queensland.

I've never been a particularly confrontational person. In the workplace, I would much rather maintain good relationships with my coworkers than engage in endless debates over something that ultimately doesn't benefit the product or the team.
Unfortunately, software developers love to argue. Whether it is about style, tooling, or entire operating systems, we are stubborn, intelligent creatures with the misfortune of believing our opinions count as facts (spoiler alert: they don't).
The flame wars don't matter, and while some debates can be healthy, there are four in particular that I wish would just end already.
1. Indentation Styles
Probably one of the more contentious — yet least valuable — debates on this list, indentation styles are a nightmare to talk about. Tabs. No, spaces. 4 of them. Or maybe 2.
Seriously, kill me now.
Highlighted in an early episode of Silicon Valley, the tabs vs. spaces debate is a self-centered one that completely ignores the realities of language and framework patterns, best practices, and long-term project maintainability. Everybody has a preference — personally, I like spaces (also known as soft-tabs, for those of you that think preferring spaces means I hit the spacebar ten-thousand times a day) — but personal preference has no place in a team setting.
Code, like writing, should read like it comes from a singular voice. That means, regardless of what you prefer, the code that you create should adhere to the standards of the project. What it doesn't mean is that you have to actually change your coding habits. When it comes to consistency, guardrails are your friend. Projects like EditorConfig exist to apply consistency to your project's formatting. Spaces, tabs, newlines. Whatever you prefer is fine, because in the end the guardrails you implement can take care of the details.
In 2013, I accepted a job at a well-known hosting company after spending the previous two years at a very early stage startup. Excited to learn what I could from a larger, better funded organization, I was instead greeted by a barrage of technological gatekeeping. One of the first "conversations" I had with one of my new coworkers — and onboarding buddy — was a backhanded review of my editor of choice.
"You'll never be productive with Editor X," he said, "we only use Editor Y here."
Three months later, I quit for decidedly greener pastures.
Whether it is Vim vs. Emacs, IDE vs. Text Editor, GUI vs. CLI, or some other arbitrary "this vs. that" debate, the tools we use as developers largely don't matter. When you claim that you are better at your job than someone else because of the tools that you use, then you are admitting that it's not you that is doing the job at all. As the saying goes, "a good carpenter doesn't blame his tools."
3. Technology Stacks
If I have to hear one more argument over which programming language or database technology is best, I'm going to lose it. Don't get me wrong, I'm a firm believer in using the right tool for the job, but sometimes we have to operate using the knowledge that we simply don't know which tool is right for a particular job. But we, as developers, often confuse what we understand and are good at with what is "best."
C++ is no better or worse than Java.
Ruby on Rails and Laravel each have their own strengths and weaknesses.
NoSQL and Relational databases are not one-size-fits-all.
Whether it is due to time or budget crunch, more often than not the choice in technology stack is less important than the outcome. Why let perfect get in the way of good? Pick the right choice for right now, and recognize that technology is always changing. You will be able to evolve your product alongside it, but arguing over which stack is better than the rest will get you nowhere.
4. Operating Systems
Remember the old "I'm a Mac. I'm a PC." commercials?
I do. And I hate them.
They imply that your operating system of choice makes you an inherently better or more productive person, which simply isn't the case. Preference is exactly that: preference. It's what works for you. On any given day, I use all three major operating systems. I'm comfortable jumping from Windows to macOS to Linux and back, because the operating system that I use doesn't matter nearly as much to me as it used to.
Unfortunately, that doesn't stop die-hard OS enthusiasts from re-sparking this debate.
But the reality is that we live in a world where cross-platform is now table-stakes. Nearly every development tool that we use works across just about every operating system you can imagine, so no one operating system is any more productive than any other. Hell, thanks to containerization, even development environments are becoming more consistent across operating systems.
The only thing that working in macOS, Linux, or Windows proves is that you have a preference for a certain style. Whether it is DIY, plug-and-play, or some combination of the two, the operating system that you use is no better or worse than what someone else uses; and before you join into the next flame war about it, I can guarantee that as productive as you are in your own environment, your opponent is just as productive in theirs.

This course was really good for me. I was able to learn the basic theory and working of how services and content providers work in Android. This course helped me alot.
I found this course very good. The professor is quite Good and Speed was also good not so fast and not so slow. Quite Balanced.
by Ben v d B•
The lessons are excellent. Unfortunately there is a lack of practical application of what's taught in the lessons. The optional exercises are a start, but aren't optimal. They are better suited to the actual material than the exercises in the previous MOOC though. Especially the lessons on services and ipc were quite good. If this course had better exercise material, it would be top!
Tricky concepts explained in a good and practicle way... But you will have to spend much time by reading and analyzing examples and solving optional exercises... And reviewing past Moocs to extract all date from this mooc.
