Right, it is not domain consistent, it just performs domain propagation. I
will update the docs accordingly.
But still, it does not succeed (it is not logically entailed) but it does
not fail yet (as it is not domain consistent). Try labeling Y and see what
happens.

Hi,
I am still not sure I understand the semantics -- the constraint is posted
with domain consistency (the default). My understanding of domain
consistency is that any values remaining in the domain is consistent with
the constraint, i.e. the constraint should not fail if the variable is
instantiated to one of the values, as long as this is the only change made.
For
Y :: [3,4], count([3,0,3,3,4], Y, =, 2)
Y is the only domain variable with more than one value, so if I understand
domain consistency correctly, then instantiating it to either
3 or 4 should succeed, but doing so fails for both values.
The documentation states that:
Supports domain consistent propagation (icl = ICL_DOM, default) and "almost"
domain consistent propagation (all other values for icl), where y is not
pruned.
(I assume by other values of icl, you exclude ICL_DEF, which behaves as
ICL_DOM as that is the default)
It seems to me the behaviour is that y is not pruned in the above, even when
the constraint is posted with ICL_DOM and ICL_DEF -- I have explicitly
posted the constraint with ICL_DOM, to check if it makes any difference, and
it does not, i.e. the example with Y::[3,4] succeeds.
Cheers,
Kish

Normal include
Requirements gathering, requirements elicitation, requirements analysis, requirements capture are some of the terms commonly and interchangeably used to represent the activity of understanding what a software product should do.
There are many techniques used during a requirements gathering. The following are some of the techniques.
Brainstorming is a group activity designed to generate a large number of diverse and creative ideas for the solution of a problem. In a brainstorming session there are no "bad" ideas. The aim is to generate ideas; not to validate them. Brainstorming encourages you to "think outside the box" and put "crazy" ideas on the table without fear of rejection.
Carefully designed questionnaires can be used to solicit responses and opinions from a large number of users regarding any current system or a new innovation.
Focus groups are a kind of informal interview within an interactive group setting. A e.g. potential users, beta testersgroup of people are asked about their understanding of a specific issue or a process. Focus groups can bring out undiscovered conflicts and misunderstandings among stakeholder interests which can then be resolved or clarified as necessary.

The command line is a way for you to communicate with the computer in its language. Asking it to help you do the things that you want to do with the information that is available on your computer or one that you are able to retrieve/create at that moment.
It is affectively like trying speaking to a deaf person, you learn how to use sign language in order to be able to communicate in a way that they will understand.
No. A lot of time was spent on the initial Workshop video and worked through the same process from there. Less time was needed to do further research and practicing with other resources.
ls – list directory content in the file which you are current in (or root if starting off with)
cd "name of directory" – changing directory. This only moves in to the directory chosen while "cd" moves it back to parent/root directory
mkdir – creating a new directory in the parent or child files that you are currently on
cat – output content of the file that is being worked on (.txt .html) in text form on the terminal
touch – creating a file that doesn't already exist
rm –r – remotely deleting the files from the directory without opening a new window
Um…. How about the whole thing? I have used terminal before to make changes to files or agreements that was already on the computer (like taking the place of root and agreeing to xcode terms of use in order to use Git for example) but I didn't know that so much could actually be done without opening so many windows! And uploading it onto GitHub remotely? Super cool.
Git is a SCM or source code manager that keeps track of the history of your work so that you can refer back to it at a later stage. Basically a very organized helper who keeps track of what you’ve done and reminds you of it when you ask.
GitHub is a space for collaborating your work with the help of Git to track its progress. It is a DVCS or Distributed Version Control System, which gives any client (or you) the ability to mirror the repository or the work that you and your colleagues have committed so far to the project that you are working on. It is affectively a service that you subscribe to in order to systematically collaborate lots of work without overwriting or stepping on anyone’s toes. Also acts like a cloud system for back ups and storage
Git is your secretary and GitHub is the place you work along side others on the same project. Everything is in the same place and you can see what everyone is doing. There is a supervisor (master) who checks and approve all your work before a final proposal in submitted.
Absolutely! Seeing as we will definitely be working on Git and GitHub throughout the course it would be hard to forget.
No because I was making changes to my terminal at the same time. Had I not done that it would have actually taken less time than the 30mins allocated.
To my understanding, GitHub workflow is the process by which a project can be worked on my many people at any stage of the process at the same time while bing able to share what they are working on and live update the master/project at anytime without 3rd part intermediaries like emails. Using and utilising branches in order to work on the same thing or something that is different to what you are doing right now without disrupting the final product progress.
I learned better by doing and seeing rather than just watching. Videos are often paused and replayed while searches were made in order to reference work and try something different. It was easier to learn by seeing how it works and what you were doing wrong then fixing it to get the outcome that I wanted. I would google the things that I did not understand and try it again and again until it worked.
I would not have watched all 7 tutorials back to back… too much information without any means to actually apply. A lot of listening and not a lot of practicing. I would have tried to find a place where Git can be practiced with examples and divided each of the stages of the online course by doing the things its teaching me until I fully understood what I was doing before moving on.
Its like doing a jigsaw puzzle with lots of people, most people find the corners and frame pieces first (working stage) then a picture is taken to keep a record of where you are just in case you stop for lunch (staged) then you come back to it and each work on a small section at a time until you are happy that this is all you can do for now, take another picture just in case you have to stop for the day (staged again) then if you or one of your friends had to leave early you can stick the picture of the work in progress on your facebook group so you can keep track of what you’ve done and the progress. Then you can go back to it and work on it together until you have finished it to a point where you want to share it with the world! and post it on your facebook with lots of smileys faces saying something like "look what I did!"
Master is a default branch that Git creates to represent the main body of work/head of project. Most of the time the master generally is a working form/code of the project. It is the main branch of the production code.
A branch can be used to create a parallel “tunnel” of the existing code/project that you can work on along side and test out new concepts or bug fix without making and physical change to the main branch. Once the branch has been conceptualised and photo types created then it can be shared with the team for further development if needed. Once the project undergone by the branch is centrally approved for change in the Main branch, a pull requested can be submitted for review and the branch can then be merged with the original or main branch as a final product (or to move on to further development down the line).
Intuitive, as this is similar to Google Docs concept where each person can be working on their individual parts of the essay locally (on their own) then they can upload their part online to the main document for others to peer review and give feedback before the final project is ready to be submitted and printed off.
For example, I saw a code online for a cool new app that helps people keep track of their wish list on a shopping site but noticed that there is no way of checking when you added it. I decide that I would add a code that includes the time stamp for this app. I then fork (copy orginal code) to my local computer and open a GitHub repo of my own for me to work on it. I can make changes as it's master and edit the code directly, or get side tracked and add some more cool features with a branch along side my master additions. Then if I think this is super awesome, it works and it would totally improve user experience, I'll submit a pull request and write something like "this might help people prioritise their wishes!".
Step by step to fork and clone:
It was when I realised that I had been forking from the wrong origin (pardon me while I giggle as I never thought I'd ever have to say that outside of hospitality) that it made more sense as to what I was suppose to do. It was nice to be able to put all the theory and the command line practices into actual tangable action. It was very satisfying.
I didn't feel frustrated at all as I feel that I was adequately prepared to use what I have learnt so far to produce the expected outcome.
It was easier than expected but around about what I had imagined a start up page would look like. I mean everyone my age remembered BEBO and dial-up right? Although the web page currently reminds me of an Error 404 page of an old website, bare and minimal, but looking at it makes me a little excted as to what I will be leaning to do next inorder to fill it out.
The resource available on foundations outlines the process in detail bit ultimately I've come to understand steps to problem solving as:
Definitely. With determination and creating benefitial habits. Its ok to not get it right the first time. I believe that hard work will always trump any challenge as long as you dont give up and have the drive and patience to get better. It doesn't have to be quickly. Any improvement is a personal win and that is how I have survived so far.
Flipped classroom is a model where students are given the core information and practices to do outside of class in order to prepare for the class. The class itself is more about applying what you have studied in a controlled setting where there is support should you need it. Mostly the class actually focuses on student centred learning and self-learning. Giving students the ability to do project based collaborative work with teacher assistance.
It is something I am used to doing so i did not find it hard. I often self reflect and TRY to learn from my mistakes. Its one of my limitations actually. My policy in life has always been if they are brave enough to ask, then I am brave enough to answer sincerely.
I was a little self concious as I tend to like doing these things in person so that I can gauge the room and whether or not I'm sharing too much. I can feel a sense of pride in my words as I feel that I was able to confidently share with others about who I am and who I want to be. That doesn't exactly stop me me shaking everytime I talk about myself though.


Gov’t lays out rules governing surveillance, informants
HAVANA (AP):
Cuba has publicly laid out the rules governing the extensive, long-standing surveillance and undercover investigation of the island’s 11 million people.
A new decree approved by President Miguel Díaz-Canel on October 8 and made public this week says prosecutors can approve eavesdropping and surveillance of any form of communication without consulting a judge, as required in many other Latin American countries. The law also creates official legal roles for informants, undercover investigators, and sting operations.
The decree is intended to “raise the effectiveness of the prevention of and fight against crime”, according to the declaration in Cuba’s register of new laws and regulations.
Cuba has been updating its laws to conform with a new constitution approved in February, which requires legal approval for surveillance.
widespread surveillance
The country’s powerful intelligence and security agencies have for decades maintained widespread surveillance of Cuban society through eavesdropping of all types and networks of informants and undercover agents, but their role has never been so publicly codified.
The decree describes a variety of roles: agents of the Interior Ministry authorised to carry out undercover investigations, cooperating witnesses who provide information in exchange for lenient treatment, and sting operations in which illegal goods are allowed to move under police surveillance.
The law allows interception of telephone calls, direct recording of voices, shadowing and video recording of suspects, and covert access to computer systems.
Unlike Cuba, many countries, including Mexico, Argentina, Guatemala, Chile, and Bolivia, require a judge to approve surveillance operations.

The evaluation data currently only drive the public leaderboard. The private leaderboard is not yet active. To avoid a situation where people could look up the answers on the web, we have a two-phase data release.
9/1-2nd data release, Submissions open for Splunk Innovation Prize
9/7 (measured by UDT)-Contest ends
9/10-deadline for prelim winners to release code (with a license that allows for anyone to run it and verify results)
9/15-deadline for public to contest the results
9/20 winners announced
First Data Release
The data for the first release are drawn from a 6-week period of blog posts and "likes" of those blog posts. The training data consist of the first 5 weeks of posts and "likes" that occurred during those 5 weeks. This data files provided (some of which contain redundant information in different forms).
At the end of September 1, 2012 (measured by UDT), the contest will be closed to new submissions and the only submissions eligible to win will be those that have attached the complete code necessary for generating the submission. At that point, the second phase of data will be released.
Second Data Release
The private leaderboard (final evaluation) data will be drawn from a future 6 week period. These 6 future weeks will be divided in the same way as the First Data Release, and prior aggregate data from the beginning of the new 6-week period will also be available.
After the Second Data Release, contestants will have one week to generate predictions based on their previously submitted code. This previously submitted code must be able to generate the new predictions with no human input or judgment. At the end of that week, preliminary winners will be announced. Kaggle will then make public the code that the preliminary winners had previously submitted with their entries. There will then be a two week period during which participants or other individuals will have a chance to replicate the results and (potentially) challenge the preliminary winners with violating the contest rules, or not having presented code that creates the results claimed.
In case of disputes during the verification process, Kaggle will select a panel to adjudicate.
Splunk Innovation Prize There will be an additional 5K prize for "most innovative use of Splunk in the contest." This could be an app, a visualization, some clever search analytics, whatever you can dream-up. Submissions will open at the end of the contest. Watch the contest page for more information.

Aurora is a small entity-component-system game engine for real-time-strategy games. It's also sort of a mod API, but more on that later...
Aurora is being developed alongside its intended use case, Forge, and still churns quite a bit. There's also lots of test code present which requires refactoring and possible removal, but the basic architecture is stable and usable.
Aurora is based on four basic classes:
Engine
Entity
Component
System
In a nutshell:
Three.js
(geometries, materials, etc.)The wiki contains more detailed information about the architecture and usage of Aurora and extensive documentation of the different classes and methods available can be found in /docs
or at ianpaschal.github.io/aurora.
"I read something above that said Aurora is 'sort of a mod API'."
That's correct. With Aurora, there's not really a distinction between core content and mods. Because all entities are both represented and saved as JSON (plus whatever other image assets or sounds), it's easy to add new units to the game without actually having to eval()
any Javascript. This is especially useful for modded multiplayer where the required mods can be safely sent to all players in the game.
Obviously this exempts "systems" from being added as they are the actual executable functions which process a world's entities, but exchanging those should eventually be possible as well as the users' discretion.
Read more on the wiki.
Aurora is licensed under the MIT license.

Rape attempt, revenge porn threat led daughter to drink acid: Muzaffargarh man | Pakistan - Geo.tv
by GEO NEWSMUZAFFARGARH: A young woman who died last week after drinking acid survived a rape attempt and was threatened with revenge porn, her father told police as they registered a first information report (FIR) over the incident on Monday.
The bereaved father noted in the FIR that two of his daughters, including the one who passed away, were blackmailed by unidentified men. The case includes charges of blackmailing and attempted sexual assault.
He added that the suspects had called both of his daughters to meet them and threatened to share doctored inappropriate images of them on the Internet if they failed to show up.
The late woman had drank acid on November 13, following which she spent more than a week in agony and, according to police, died on November 21.

THE PILLOW BOOK A film review by James Berardinelli Copyright 1997 James Berardinelli
RATING (0 TO 10): 7.5 Alternative Scale: *** out of ****
United Kingdom, 1996 U.S. Release Date: beginning 6/97 (limited) Running Length: 2:06 MPAA Classification: No MPAA Rating (Nudity, sex, mature themes) Theatrical Aspect Ratio: 1.66:1 and 2.35:1
Cast: Vivian Wu, Ewan McGregor, Yoshi Oida, Ken Ogata, Hideko Yoshida Director: Peter Greenaway Producer: Kees Kasander Screenplay: Peter Greenaway Cinematography: Sacha Vierny U.S. Distributor: Cinepix Film Properties In English and Japanese with subtitles
Calligraphy is one subject that not many movies have explored, and none has approached it in quite the way that British director Peter Greenaway does in his latest motion picture, THE PILLOW BOOK. To use the film's own words to describe it, this is about the "two things in life that are dependable: the delights of the flesh and the delights of literature" and how they can be melded into one. If you're looking for something off the beaten path this summer, THE PILLOW BOOK won't disappoint. Whatever its shortcomings, this film is different.
Of course, considering the director, that's hardly surprising. Greenaway has routinely spurned traditional movie making techniques, preferring to use celluloid as an experimental canvas. His reputation has been formed largely as a result of a series of intriguingly unconventional motion pictures, including PROSPERO'S BOOKS, a bizarre re-invention of Shakespeare's THE TEMPEST, and THE COOK, THE THIEF, HIS WIFE AND HER LOVER, a twisted fable about an eloquent gangster getting his just desserts. The closest Greenaway has ever come to being mainstream is THE COOK, but, considering the relatively widespread distribution that THE PILLOW BOOK is likely to receive, that may change.
While there's nothing especially groundbreaking or difficult to grasp in THE PILLOW BOOK, Greenaway's experimentation here still has the power to alienate audiences who aren't prepared for what the film offers. As has been true in his past efforts, there are copious amounts of full frontal nudity, and it seems that lead actors Vivian Wu (THE JOY LUCK CLUB) and Ewan McGregor (TRAINSPOTTING) perform half of their scenes without any clothes on. Nevertheless, by keeping the audience at arm's length, Greenaway manages the impressive feat of de-eroticizing the nudity.
For the most part, the director seems more concerned about technique than narrative and character development. The plot functions more as a series of markers for Greenaway's stylistic riffs than a necessary aspect of the movie. Indeed, THE PILLOW BOOK is so visually arresting that it's capable of holding our attention for two hours largely on the strength of its images. There are pictures-within- pictures, French song lyrics rolling across the bottom of the screen, multiple aspect ratios, color bleeding into black-and-white scenes, and other intriguing methods of composition. Even simple shots, such as a swirl of ink-saturated water being sucked into a drain -- a color image that's all black-and-white -- can be striking. And, for those who enjoy a little bafflement, there's a sequence near the end where the dialogue is in Japanese, but Greenaway intentionally does not use subtitles.
The only character of any real importance in THE PILLOW BOOK is Nagiko, a Japanese-born fashion model with obsessions for calligraphy, physical pleasure, and revenge.  Nagiko adores her father almost to the point of worship, and is horrified to learn that, to get his work published, he has to submit to homosexual relations with his publisher (Yoshi Oida). To make matters worse, that same publisher arranges for Nagiko to be trapped into marrying a cruel, callous man who views her as an object, not a person. Eventually, fed up with her life, she flees Japan for Hong Kong, where she begins her career.
When she was little, Nagiko's aunt would read her excerpts from the PILLOW BOOK OF SEI SHONAGON, the 1000-year old diary of a courtesan. In Hong Kong, Nagiko begins her own pillow book, but, instead of writing on paper, she uses the bodies of her lovers. They, in turn, utilize her flesh for their calligraphy. Nagiko's quest is for the perfect lover/calligrapher combination, but it becomes a difficult search. As she says, the older men are not interested in the pleasure she can provide, and the younger men are easily distracted. Then she meets Jerome (Ewan McGregor), an Englishman in Hong Kong, who proves not only to be her artistic match, but offers the means by which she can enact a long-dormant plan of vengeance against her father's publisher.
As Nagiko, Vivian Wu gives an impressive performance, using her bare skin as a tablet for the calligrapher's ink and her acting ability as a means to flesh out her character. Ultimately, Nagiko becomes the only well-realized personality in THE PILLOW BOOK. The supporting characters who surround her, including Ewan McGregor's Jerome, are shallow and thinly-realized, often functioning more as plot devices than individuals. Wu's Nagiko is THE PILLOW BOOK's only truly human element.
There's something admittedly fascinating about the way Greenaway explores this mixture of calligraphy and the human form. However, as unique as this combination may be, it's actually one of THE PILLOW BOOK's few original ideas. Other directors may hesitate to venture into such unfamiliar territory, but Greenaway has been here before. In its approach to sexual obsession, art, and revenge, THE PILLOW BOOK often recalls THE COOK, THE THIEF, HIS WIFE AND HER LOVER, sometimes almost to the point of cannibalization. Visually, however, THE PILLOW BOOK erupts in a manner that causes THE COOK (which was stylistically memorable in its own right) to pale in comparison.
The great irony of this film, which is (at least on one level) about the power of writing, is that the words are of secondary importance to the overwhelming visual presentation. The camera, not the script, dominates our response to Greenaway's film. In the final analysis, THE PILLOW BOOK has much more to show than it has to say.

Trade data is often reclassified following different standards; see Concordance Table for all mappings that are possible using comtradeRggregator
.
However, in all those cases the internal logic of the conversion is that we use ‘all’ trade data, which is then mapped onto a different classification. What if, in turn, we want to extract only a set of traded commodities that belong to only a specific sub-group of the target classification?
In the example below, we assume we want to extract all SITC Rev. 2 (S2
) trade data that belongs to a very specific manufacturing sector, say, ISIC Rev. 2 (I2
) sector 3530 - Petroleum refineries
. We can accomplish this in a few simple steps:
First, we load the comtradeRggregator
package.
Next, we extract all S2
codes that correspond to the I2
sector 3530
which we want to extract:
comm_petrol <- S2_I2 %>%
filter(`ISIC Revision 2 Product Code` == 3530)
comm_petrol
#> # A tibble: 13 x 4
#> `SITC Revision 2 ~ `SITC Revision 2 Pro~ `ISIC Revision 2~ `ISIC Revision 2 ~
#> <chr> <chr> <chr> <chr>
#> 1 334 Petroleum products,r~ 3530 Petroleum refiner~

#> 6 33522 Benzole 3530 Petroleum refiner~
#> 7 33523 Toluole 3530 Petroleum refiner~
#> 8 33524 Xylole 3530 Petroleum refiner~

#> 12 33542 Petroleum coke 3530 Petroleum refiner~
#> 13 33543 Bituminous mixtures ~ 3530 Petroleum refiner~
In the next step, we use the SITC commodity codes of comm_petrol
as an input argument for the API query:
data_extract <- download_Comtrade(
year = "2018",
frequency = "annual",
countries = "France",
partners = "Germany",
nomenclature = "S2",
commodity = comm_petrol %>% pull(`SITC Revision 2 Product Code`),
select.stats = "trade_value_usd"
)
Finally, we re-classify the extracted data back to S2
using convert_Comtrade()
:
convert_Comtrade(data_extract,
classification.from = 'S2',
classification.to = 'I2') %>%
distinct(`ISIC Revision 2 Product Code`)
#> # A tibble: 1 x 1
#> `ISIC Revision 2 Product Code`
#> <chr>
#> 1 3530

Chapter 7 Functions of Continuous Distributions
7.1 Probability density functions
7.1.1 Summation Doesn’t Work
Let \(X\) be a random variable representing the height in feet of a randomly selected person. What is the probability that \(5.9 \leq X \leq 6.1\)? If \(X\) was discrete we could calculate the probability as a sum: \[\sum_{5.9 \leq x \leq 6.1} p(x)\] This sum doesn’t make sense for a continuous random variable because \(p(x)=0\) for all values of \(x\). Intuitively, if there are infinitely many possible heights than having a height of exactly \(6\) feet is just one of these infinite outcomes and the probability of it happening is \(\frac{1}{\infty}=0\).
7.1.2 Using Integrals
Let’s look at a graph of the probability density function of heights. The probability density function (or PDF) is a special function where the area under the curve represents a probability. This means we use integrals instead of summations for continuous random variables. The area below represents \(P(5.9 \leq X \leq 6.1)\).
Approximating the area above with a trapezoid: \[\begin{align} P(5.9 \leq X \leq 6.1) &= \int_{5.9}^{6.1} f(x) dx \notag \\ &= \text{base} \cdot \frac{h_1 + h_2}{2} \notag \\ &= (6.1 - 5.9) \cdot \frac{f(5.9) + f(6.1)}{2} \notag \\ &= .2 \cdot \frac{.4+.38}{2} \notag \\ &= .078 \notag \end{align}\]
7.1.3 Defining Probability Density Functions
The function \(p(x)\) we sum in a discrete distribution is a probability mass function and the function \(f(x)\) we integrate in a continuous distribution is a probability density function. This is similar to physics where a single point has no mass but we can integrate the density to find the mass of a region. Note that we us \(p(x)\) for discrete distributions and \(f(x)\) for continuous distributions.
Probability density functions have some special properties. A probability density function can’t be negative because probabilities aren’t negative. The total area under the curve must be \(1\) since the probability of all possible outcomes is \(1\). The integral from \(a\) to \(b\) must calculate \(P(a \leq X \leq b)\).
Definition 7.1 (Properties of PDF)
\(f(x) \geq 0\)
\(\int_{- \infty}^{\infty}f(x) = 1\)
\(\int_{a}^{b}f(x) = P(a \leq X \leq b)\)
7.1.4 Cumulative Distribution Function
As before we define the cumulative distribution function \(F(x) = P(X \leq x)\). For continuous random variables: \[F(b) = \int_{-\infty}^{b}f(x)dx\] It doesn’t matter if inequalities are strict or not for continuous variables because \(P(X \leq x) =P(X<x)\). This is because \(P(X=x)=0\): \[P(X \leq x) = P(X < x) + P(X=x) = P(X<x)+0=P(X<x)\] Here are some useful properties of the CDF:
Definition 7.2 (Properties of CDF)
\(0 \leq F(x) \leq 1\)
\(F(x)\) is an increasing function because the area under the curve increases as the upper bound on the integral moves to the right.
\(P(a \leq X \leq b) = F(b) - F(a)\)
\(P(X \geq a) = 1 - F(a)\)


Declaring a before function
One of the most powerful features of Form-O-Fill is the ability to run a block of code before the form filling starts
and use the data retrieved there to fill in the values.
This is called a "before function". There can only be one before function per rule.
Using a before function you can eg. fetch test data from a service to use later in your value functions.
Defining a before function is easy:
Just under the name:
definition of your rule ...
name: "Before functions rock!",
Add a before function. The first parameter will be the
resolve
function which you will need to call with the data you generated.
The second parameter is a
context object containing the parsed url parts of the tab to be filled (and other goodies).
before: function(resolve, context) {
Now request some data. You can use the globally accessible jQuery
for that like so:
jQuery.getJSON("http://api.someservice.com/search?q=" + context.url.query).done(function(data) {
When the data has been fetched (asynchronously), return the data using resolve(data)
resolve(data);
You can use the data resolved in a before function inside you value functions
fields: [{
Find the field ...
selector: "input[type=text]",
Use the second parameter to the value function ($data
).
It contains the structure you resolved in the before function.
value: function($element, $data) {
// Assuming the above call returned { myReturnValue: "Hello" }
return $data.myReturnValue;
Hint: If the fetched json data needs no transformation, resolve
can also be passed as a function reference to done
: jQuery.getJSON('...').done(resolve);
.
Providing multiple before functions in an array
You call also pass an array of functions to "before"
.
Those will be resolved and the resulting data
argument to a value function will then be an array of resolved data.
before: [
function(resolve) { resolve("a"); },
function(resolve) { resolve("b"); }
],
fields: [{
selector: "input",
value: function(dataArray, env) {
// dataArray === ["a", "b"]
}
}]
Canceling the rule processing using Libs.halt()
If you need to cancel the processing of a rule based on a condition in your before function you can do so.
Just resolve
with a call to Libs.halt()
.
The rule or the workflow will be immediatly canceled and a message will be displayed.
before: function(resolve, context) {
... do some stuff ...
resolve(Libs.halt());
}
You can customize the message that is displayed when the rules/workflow is canceled:
before: function(resolve, context) {
... do some stuff ...
resolve(Libs.halt("Custom message to be displayed"));
}

Soooooo... At the end of chapter 7 of Chris Pine's Learn to Program is an exercise where you create a program where you talk to Grandma who is hard of hearing. The initial program is really simple, then he proposes a few changes that increase the complexity slightly. I thought it was cute, and sounded like fun, so I did the challenge.  Even the extended challenge part!
But then I realized I couldn't show it to anyone because I don't know how to embed Ruby into web pages yet. And that's when I fell down the rabbit hole. I spent an hour converting the program into JavaScript and embedding it into a web page... so I can show off my one trick pony Ruby program.
So, uh, yeah. That's it. Press the button to play. If you've read the exercises at the end of chapter 7, you'll figure out how to end the conversation. If you haven't figured it out, it involves the word "bye". Multiple times. Oh, and it doesn't work if you have pop-ups turned off. I'd work on that, but I think I've blown WAY too much time on this already...


Martin Keown raves about Liverpool FC duo in England’s 4-0 win
Arsenal legend Martin Keown heaps praise on Liverpool FC duo Trent Alexander-Arnold and Joe Gomez
by The Sport Review staffMartin Keown believes Liverpool FC duo Trent Alexander-Arnold and Joe Gomez merit a regular place in the England starting XI.
The Liverpool FC centre-half started alongside Harry Maguire for England’s 4-0 win against Kosovo despite falling down the pecking order at Anfield this term.
Gomez is behind Virgil van Dijk, Joel Matip and Dejan Lovren in Jurgen Klopp’s squad after the England international returned from a serious injury earlier this year.
Alexander-Arnold impressed at right-back in the England team as the 21-year-old continues his promising start to the season for both club and country.
Although the Liverpool FC starlet didn’t score or make an assist in England’s 4-0 victory over Kosovo, Alexander-Arnold laid down a marker in the race to secure a starting spot at Euro 2020.
Former Arsenal defender Keown believes Alexander-Arnold and Gomez warrant a starting spot in Southgate’s England team.
“[Gareth] Southgate will have left Kosovo asking himself questions,” Keown wrote in his Daily Mail column.
“Who starts at the back alongside Harry Maguire? I’d go with Joe Gomez.
“Southgate likes to pick players who play regularly for their clubs.
“Gomez has not been starting as much as he would like for Liverpool, but I’d break that rule for him.
“The attack-minded Trent Alexander-Arnold does not always act as a right back, but that is because he is one of the best going forward.”
Alexander-Arnold has scored one goal and has made three assists in 12 games in the Premier League so far this season.
His only goal of the campaign came in a 2-1 win against Chelsea FC at Stamford Bridge back in September.
Gomez has made one Premier League start and has come off the bench three times to rack up a mere 99 minutes of top-flight football this term.


Inside the Making of Kylie Jenner's Custom Marilyn Monroe and Madonna Halloween Costumes
by Alyssa BaileyThe typical Kardashian-Jenner Halloween costume doesn't come from a costume store; it comes from a designer. In the case of Kylie Jenner this year, who wore six costumes total, Jenner's stylist Jill Jacobs worked with Bryan Hearns to create Jenner's Madonna look and Alejandro Collection to have Jenner's Marilyn Monroe outfit constructed.
ELLE.com talked to designers Bryan Hearns and Alejandro Peraza of Alejandro Collection about what went into making two of Hollywood's biggest Halloween costumes this year.
Madonna
Jenner dressed up as Madonna at the 2003 MTV VMAs with her friend Anastasia Karanikolaou, who was Britney Spears. Why did they choose that moment and to recreate the two's big kiss? "The girls are OBSESSED with pop culture so they really wanted to pick an iconic moment that everyone is familiar with," Hearns said.
Detail was critical. "I wanted to make sure the designs were as close to the original as possible," Hearns said. "We spent a lot of time researching videos and all pictures from the performance to make sure we got it 120 percent right. It's still my top fave performance ever so I already had a good idea of how we were going to recreate the look."
"Every piece is so different so took a while to create all of the looks," Hearns added. "I wanted to makes sure it looked as close as possible to the original so sourcing the fabrics was a fun challenge. Britney’s look was very bridal vibe so that was my first time doing that type of look, which was a great first experience."
Initially, Jenner was going to be Christina Aguilera. "Kylie has been Christina Aguilera before so naturally she wanted to do another iconic Xtina look," Hearns said. "When Stassie and Kendall [Jenner] joined forces, they were all happy to play dress up and go with the flow as far as who would play who." Kendall Jenner ultimately wasn't photographed in the Christina look.
"I loved how all the girls changed up who they were originally supposed to be to shock all of us," Hearns added of the surprise. "Of course, they all still looked amazing."
Marilyn Monroe
For V magazine's Halloween cover, Jenner appeared as a spot-on Marilyn Monroe from Gentlemen Prefer Blondes. Jenner specifically wanted to pay homage to one of Monroe's most iconic film moments ever: When Monroe performed "Diamonds Are a Girl's Best Friend."
The dress didn't come together last minute: "Kylie’s Marilyn look has been weeks in the making; I received a call from her stylist Jill [Jacobs] and sent over sketches," Alejandro Peraza said. "Kylie always loves a pop culture moment, and after all, no one knows better than Kylie when it comes to diamonds being a girl’s best friend."
Peraza's goal was to create a replica of the original dress. "The costume was recreated meticulously, and [I was] paying very close attention to the original design," Peraza said. "[I] loved making the bow, perfecting the gloves, then tying it all [together] with the perfect belt. The whole process was a dream come true for me and my atelier."
It took just two weeks for the garment to be constructed, Peraza said. "The dress has built-in boning, perfectly confected to give Kylie the Marylin look," he explained. "The look came together in two weeks from start to finish. We had to custom dye fabric to make the gloves so it matched the silk fabric perfectly, as well as unusually long length like the ones from the 'Diamonds Are a Girl’s Best Friend' song."

parameter: A numeric value that is part of a {_program}, that controls some single aspect of a sound. Every parameter has a name, a range of internal numeric values which are used over MIDI, a default value in a {_scratch_program}, and a more user-friendly representation of each possible numeric value. For instance, an oscillator pitch is shown using note symbols like "G#4", while a modulation selector value is shown as the name of the modulation source, like "envelope 2A".
Parameters are categorized as {_selector_parameter selector parameters}, which have distinct settings, and {_variable_parameter variable parameters}, which represent a continuous range of values with a certain resolution. On the Digital Chroma, parameters are also categorized as "regular", if they were included in the original Chroma, or "{_extended_parameter extended}", if they are new.

Magnetic field¶
It can vary over space, \(\vec{r}\) and time, \(t\):
Equilibrium Magnetization¶
At equilibrium the net magnetization, \(\vec{M} = [0,0,M_0]^T\) is oriented in the direction of the main magnetic field, \(\vec{B} = [0,0,B_0]^T\) (by convention along the z-axis) and has an amplitude of:
\(N\) spin density
\(\hbar\) Planck’s constant
\(\gamma\) gyromagnetic ratio
\(B_0\) magnetic field
\(I_Z\) spin number (1/2 for hydrogen)
k = Boltzmann’s constant (8.62e-5 eV/K or 1.38e-23 J/K)
T = temperature (human body temperature = 310 K)
Boltzman distribution¶
This is the ratio of spins in the spin-up, \(N_\uparrow\), to the spin-down, \(N_\downarrow\), states. This can also be used to derive the equilibrium magnetization above.
From this distribtion, the “Polarization” can be defined as the difference between spin up and spin down states, divided by the total number of spins, which describes the fraction of spins that contribute to the MR signal:
If the exponent is small (or, when the polarization is low), this simplifies to
Bloch Equation¶
The Bloch equation describes the behavior of the net magnetization, \(\vec{M}\) in a magnetic field, \(\vec{B}\), and can describe the vast majority of all MRI phenomena
\(T_1\) Longitudinal (\(M_Z\)) or spin-lattice relaxation time constant
\(T_2\) Transverse (\(M_{XY}\)) or spin-spin relaxation time constant
Precession¶
The first term in the Bloch equation means that the net magnetization, \(\vec{M}\) rotates around the magnetic field, \(\vec{B}\), with a left-handed rotation. This rotation is sometimes referred to as precession.
To observe this, we neglect relaxation (\(T_1, T_2 \rightarrow \infty\)):

RF Excitation¶
RF excitation occurs when an oscillating magnetic field is applied orthogonally to the main magnetic field. If we apply RF at the Larmor frequency, the magnetic field would be
When applied at the Larmor frequency, the applied RF energy and the net magnetization are in resonance, and we achieve excitation.
RF excitation (rotating at the Larmor frequency)
Lab versus Rotating Frame¶
For simplification, we use the so-called “rotating frame” - a reference frame that is rotating around the main field (z-axis) at the Larmor frequency, \(\omega_0 = \gamma B_0\), which greatly simplifies the interpretation, visualization, and math when analyzing the Bloch equation. This is in contrast to the “lab frame” or “stationary frame”.
In the rotating frame, the magnetic field is
and RF excitation is a rotation around this simplified representation of the magnetic field.

title(['Non-resonant magnetic field (in RF direction)'])
The above simulation shows when an additional magnetic field is applied orthogonal to the main magnetic field, but is not applied at the Larmor frequency. There is no creation of transverse magnetization.
Below, this is corrected, and the RF pulse is applied at the Larmor frequency, \(\omega_0 = \gamma B_0\):
% RF pulse at Larmor frequency
% lab frame
B = [B10*cos(2*pi*f0*t);B10*-sin(2*pi*f0*t);B0*ones(1,length(t))];
Mall = zeros(3,length(t));
Mall(:,1) = M_equilibrium;
for It = 1:length(t)-1
Mall(:,It+1) = bloch_rotate(Mall(:,It),t(It+1) - t(It),B(:,It));
end
plot(t,Mall)
xlabel('time (ms)'), ylabel('Magnetization')
legend({'M_X', 'M_Y', 'M_Z'}, 'location', 'northwest'), legend boxoff
title(['Resonant RF pulse'])
And now with a resonant RF pulse, we have excitation of the net magnetization away from the direction of the main magnetic field, and creation of transverse magnetization, \(M_X\) and \(M_Y\).
However, it is hard to visualize the transverse magnetization because it is rotating at the Larmor frequency. To better visualize the transverse magnetization, we use the rotating frame:
% rotating frame
% RF pulse at Larmor frequency
B = [B10;0;0];
Mall = zeros(3,length(t));
Mall(:,1) = M_equilibrium;
for It = 1:length(t)-1
Mall(:,It+1) = bloch_rotate(Mall(:,It),t(It+1) - t(It),B);
end
plot(t,Mall)
xlabel('time (ms)'), ylabel('Magnetization')
legend({'M_X', 'M_Y', 'M_Z'}, 'location', 'north'), legend boxoff
title(['Resonant RF pulse in rotating frame'])
Relaxation¶
The net magnetization \(\vec{M}\) will return to equilibriuam (\(\vec{M} = [0, 0, M_0]^T\) oriented with the main magnetic field along the z-axis) with time constants \(T_1\) and \(T_2\).
\(T_1\) Longitudinal (\(M_Z\)) or spin-lattice relaxation time constant
\(T_2\) Transverse (\(M_{XY}\)) or spin-spin relaxation time constant
In the rotating frame, without any applied RF energy, the Bloch equation is simplified to
This has solutions of
or
t = linspace(0,1); % s
M0=1;
T1 = .8; T2 = .1; % s
M_equilibrium = [0,0,M0].';
flip= 90;
gammabar = 42.58; % kHz/mT
T = 1; % 1 ms pulse duration
% calculate RF pulse amplitude (milliTesla)
B10 = flip*pi/180 / (2*pi*gammabar*T)
% apply RF tip
M_start = bloch_rftip(M_equilibrium, T, B10)
Mall = zeros(3,length(t));
for It = 1:length(t)
Mall(:,It) = bloch_relax(M_start,t(It),M0,T1, T2);
end

git-web--browse - Git helper script to launch a web browser
git web--browse [OPTIONS] URL/FILE ...
This script tries, as much as possible, to display the URLs and FILEs that are passed as arguments, as HTML pages in new tabs on an already opened web browser.
The following browsers (or commands) are currently supported:
h'-04'(buh'+03'c
firefox (this is the default under X Window when not using KDE)
h'-04'(buh'+03'c
iceweasel
h'-04'(buh'+03'c
seamonkey
h'-04'(buh'+03'c
iceape
h'-04'(buh'+03'c
chromium (also supported as chromium-browser)
h'-04'(buh'+03'c
google-chrome (also supported as chrome)
h'-04'(buh'+03'c
konqueror (this is the default under KDE, see Note about konqueror below)
h'-04'(buh'+03'c
opera
h'-04'(buh'+03'c
w3m (this is the default outside graphical environments)
h'-04'(buh'+03'c
elinks
h'-04'(buh'+03'c
links
h'-04'(buh'+03'c
lynx
h'-04'(buh'+03'c
dillo
h'-04'(buh'+03'c
open (this is the default under Mac OS X GUI)
h'-04'(buh'+03'c
start (this is the default under MinGW)
h'-04'(buh'+03'c
cygstart (this is the default under Cygwin)
h'-04'(buh'+03'c
xdg-open
Custom commands may also be specified.
-b <browser>, --browser=<browser>
Use the specified browser. It must be in the list of supported browsers.
-t <browser>, --tool=<browser>
Same as above.
-c <conf.var>, --config=<conf.var>
CONF.VAR is looked up in the Git config files. If it(cqs set, then its value specifies the browser that should be used.
The web browser can be specified using a configuration variable passed with the -c (or --config) command-line option, or the web.browser configuration variable if the former is not used.
You can explicitly provide a full path to your preferred browser by setting the configuration variable browser.<tool>.path. For example, you can configure the absolute path to firefox by setting browser.firefox.path. Otherwise, git web--browse assumes the tool is available in PATH.
When the browser, specified by options or configuration variables, is not among the supported ones, then the corresponding browser.<tool>.cmd configuration variable will be looked up. If this variable exists then git web--browse will treat the specified tool as a custom command and will use a shell eval to run the command with the URLs passed as arguments.
When konqueror is specified by a command-line option or a configuration variable, we launch kfmclient to try to open the HTML man page on an already opened konqueror in a new tab if possible.
For consistency, we also try such a trick if browser.konqueror.path is set to something like A_PATH_TO/konqueror. That means we will try to launch A_PATH_TO/kfmclient instead.
If you really want to use konqueror, then you can use something like the following:
[web] browser = konq [browser "konq"] cmd = A_PATH_TO/konqueror
Note that these configuration variables should probably be set using the --global flag, for example like this:
$ git config --global web.browser firefox
as they are probably more user specific than repository specific. See git-config(1) for more information about this.

We love tacos. All kinds of tacos. And we love being creative with the way we make our tacos.
Some taco joints offer a set, finite menu of tacos to choose from. At Taco Cloud, we want to share the joy of taco creativity with you, allowing you to design your own tacos from a palette of fresh and delicious ingredients. While we may offer some of our creations for you to try, the real fun is when you create your own tortilla-wrapped works of art.
And, even though we love tacos and creativity, we prefer to avoid doing complex math. That's why all tacos are priced modestly at $4.99 each, no matter how many or what ingredients you choose.
Click here to get started on your taco masterpiece!

[gecode-users] Change of behaviour since Gecode 3
Vincent Barichard
Vincent.Barichard at univ-angers.fr
Wed Mar 18 15:22:41 CET 2009
Hi,
I noticed a change of behaviour with Gecode 3. When I run some test problems I
get a different number of propagations and different domains. Is there any
trouble in some propagators or maybe I missed something.
I attached a small example:
test.cc is for Gecode 2.2
test.cpp is for Gecode 3
Thanks for your help.
Cheers,
Vincent

- The Question of Principles
- Principles are good until they aren’t
- Lacking principles is either “inconsistent and hypocritical” or “adaptive and resilient” depending on how you spin it
- The trick with principles is that they have to be somewhere between universal (which won’t work because it makes you completely inflexible… “might break but will never bend”… white-knuckling through life) and completely non-existent (“arbitrary and capricious” — a real flake)
- Essentially the idea is that you need context-sensitive principles: not principles that cut across situations but principles that adapt to changing circumstances. Whether or not these are still principles is semantic. The point is to find a middle way between iron inflexibility and flaky unreliability.

I would suggest giving the ability to add attachments to weapons and then having the graph change according to that. The plot is really nice however it does not allow for a much more accurate representation based on what you prefer on your gun.

Its definetly too much work to have graph for every combination of any possible attachment and weapon.
Sorry, it will never be integrated. You must calculate that stuff manually.
What will maybe come in the future is more detailed attachment information.

fair enought, i was thinking more allong the lines of a integrated graph calculator built into bblog which calculates on the fly, if that is even possible
BrainFooLong

I also thought about on the fly calculator.
This is so huge work and maybe not really possible, maybe it comes in the future but i cannot promise it.

If you are in a car and a sandstorm gets the drop on you, it can put you in a very dangerous situation. Your visibility can be reduced to virtually nothing, and it’s not just yourself that your going to have to worry about. All the other clowns on the road can be particularly dangerous, if visibility is poor, they are less likely to see you.
The advice is to make your way off the road at the next safe opportunity, park up on the side, and turn all your lights off. Sounds a bit crazy that to avoid getting hit accidentally, you need to make yourself less visible, but other drivers can be drawn to your headlights like moths to the flame.
If your car is there, then that must be where the road goes, right? And so it is likely for people follow your lights and crash into you.
Once you are safely off the road and your lights are off, its time to close all your windows, any vent that brings in air from outside and sit back, relax, and relish the prospect of telling your mates you were in a sandstorm.
If you get caught in a sandstorm while you are out and about on your treks, find the nearest big land form, such as a rock, and take shelter by the side of it. If you are unable to find a shelter quick enough, stay put and do not move. By moving you will put yourself at greater risk from potential hazards, plus you may get yourself lost. If you are in a large group link arms to keep together and prevent anyone from getting separated.
Remember the first point I said about preparation? Now is the time to put it to good use.  It is likely to be extremely dry in a sandstorm so it is worth applying petroleum jelly in your nostrils to prevent them from drying. Wearing long clothing will prevent your skin from getting ripped apart, the sand being blown against your skin will feel like someone giving you a rubdown with some coarse sandpaper.

Sandstorms can happen in unison with thunder storms, so be prepared to experience lightening, and take any measures that will help avoid a lightening strike. The high winds can pick up more than just sand, so protect your head and be on the lookout for large flying objects, the last thing you want is to be knocked out by a flying tree stump.
After you have followed all of these steps, the only thing you can do is wait it out. A game of eye spy is always fun in a sandstorm, but you might run out of things to spy after the first go
