Most I found the recommendation to use this inside the widget.
<!-- language: lang-js -->
_init: function() {
this._internalData = {};
},
But this data is not internal :(
<!-- language: lang-js -->
console.log($("#View1").JSTreeTable("").data().JSTreeTable._internalData);
The above code gives full access to the internal data.
Is there another way?

When a User is Editing an entry, I wish to fire off a similar piece of code, only this time I would like to retrieve the entry ID in the QueryString which will look something like this

Does anyone know how I can get the value 41 using JQuery or is this even possible?

The main problem comes when I want to define abilities for the index action. In an index action, the block does not get executed, so I guess it's not an option.
Let's illustrate it. If I wanted only the owner to be able to index the bets, this would be enough:
can :read, Bet, :user => { :id => user.id }
But I need the acceptable ids to be a range, one defined by all the friends of the user. Something like:
if (bet.user == user) || (bet.user.friends.include? user)
can :read, Bet
end
But this is not correct CanCan syntax.

Suppose I have a directory structure like this:
app/
core/
bin/
runner
Gemfile
...
Gemfile
lib/
The "core" is an application which has its own Gemfile and Gemfile.lock. I don't want to modify core in any way. app/Gemfile is part of my plugin to core, which also has a Gemfile (listing its own dependencies that are additional to core/Gemfile).
I can "bundle install" from the app/core/ and app/ directories.
How can I run core/bin/runner from the app/ directory in such a way that it will include all the Ruby gems from both app/core/Gemfile and app/Gemfile?
**Background**
I am writing a plugin for Logstash, using C Ruby. Logstash includes its own Gemfile; once all dependencies are fetched, the total package size is about 40MB.
I want to run Logstash in Heroku. To avoid putting 40MB of stuff into Git, I have forked the Ruby buildpack (https://github.com/inscitiv/heroku-buildpack-logstash) and modified it to download Logstash, unpack it, and use its Gemfile.
This works fine, but I am stuck with the Gemfile provided by Logstash. For my plugins, I want to add new dependencies that my plugins will use; I don't really want to fork Logstash and change its Gemfile in order to accomplish this.
Instead, I want to unpack Logstash into its own directory (logstash/), and then I want to overlay my plugin code, including Gemfile for dependencies, on top of it. Then I want to run a Heroku "worker" process which will run logstash, specifying "." as the plugins directory, and has access to all the gems from both Gemfiles.

Currently, I am aware of Flash - and JavaScript for HTML5 Canvas - for applicability like this.
### Flash ###
_ActionScript 2_
* Language: ActionScript 2
* Compiler: [mtasc](http://www.mtasc.org/)
* Delivery: Player software: [Gnash](http://www.gnu.org/software/gnash/) (standalone or browser plugin, Linux)
_ActionScript 3_ (_[single file "applet" example](http://stackoverflow.com/questions/10243353/yet-another-local-file-access-in-actionscript-3-q-u-e-stion)_)
* Language: ActionScript 3
* Compiler: [mxmlc](http://livedocs.adobe.com/flex/3/html/compilers_14.html), part of Flex SDK ([here](http://www.adobe.com/cfusion/entitlement/index.cfm?e=flex3sdk) or [here](http://www.adobe.com/devnet/flex/flex-sdk-download.html))
* Delivery: Player software: [Lightspark](http://lightspark.github.com/) (standalone or browser plugin, Linux)
### HTML5 Canvas ###
* Language: JavaScript + library APIs
* Compiler: none
* Delivery: HTML5 Canvas-enabled web browser (`firefox`, ...)
Animation functionality in this case, as of now, seems dependent on external libraries, many of which are described in [HTML5 Canvas Vector Graphics?](http://stackoverflow.com/questions/4340040/html5-canvas-vector-graphics); see also:
* [10 Super JavaScript Animation Frameworks | jQuery4u](http://www.jquery4u.com/animation/10-super-javascript-animation-frameworks/) (Jan 2012)

* [10 Impressive JavaScript Animation Frameworks](http://sixrevisions.com/javascript/10-impressive-javascript-animation-frameworks/) (Jun 2009)
(<sub>"<code>N __ JavaScript Animation __</code>" is now a meme, apparently `:)`</sub>)
Typical JavaScript libraries mentioned in this context are:
* Processing.js
* Raphaël
* Cake
* The Burst Engine
------
Basically, I find **ActionScript** as language very suitable for the task - I can draw vectors in code using `lineTo`; treat them as `MovieClip` objects; specify framerate and run code `onEnterFrame`, as well as have access to keyboard and mouse interaction events, and ability to run timed code (`setTimeout`, `setInterval`).
I also don't have a problem with the compilation step that generates the `swf`; besides some error checking, I think it is also responsible for the decent performance of Flash vector movies. I work on Linux, and for myself, I could relatively easily set up one of the above development environments. Problem is the delivery - if I want an open-source delivery, then I don't have cross-platform compatibility anymore (as the known open-source players seem to be Linux only).
In comparison, **JavaScript**/HTML5 Canvas would be great - since for delivery, I'd count on reproduction in established open-source web browsers. However:
* first problem is performance - most examples I've seen cause my `firefox` 13 in Ubuntu to go nearly 100% CPU on both processors, while doing relatively average animations (<sub>and I can imagine the browser choking, should I want to animate some N=250 circles in my example stated above</sub>).
* second problem is dependency on external libraries, so the concept of single source-file application becomes more complicated (<sub>Also, vendors may disappear - not sure if it's temporary, but currently I cannot access the site [hyper-metrix.com](http://hyper-metrix.com/#Burst) often given as home of the Burst JS library</sub>)
* finally - while JavaScript and ActionScript (as I understand) should follow same/similar ECMAScript specifications - some of the JavaScript libraries are not really intended for treatment of vector drawings as objects: some, instead, try to simplify access to effects like "tweening" and gradual color changes through a simple, one-liner language construct, which something I actually do _not_ need in this case (<sub>thus, finding a suitable Javascript syntax (for this particular applet use I intend) could also be a problem</sub>)
-----
So, given my notes above, what other alternatives do I have? I'm pretty sure `python` would have something - does `perl` have something too, or any other languages? Also, what would the requirements for delivery be (besides installing a given language interpreter for a given operating system), and what could one expect performance-wise (e.g. can random linear motion of 250 circles in a 640x480 px window at 45 fps, be reasonably expected on an Atom class netbook)?
Many thanks in advance for any answers,

Currently, I am aware of Flash - and JavaScript for HTML5 Canvas - for applicability like this.
### Flash ###
_ActionScript 2_
* Language: ActionScript 2
* Compiler: [mtasc](http://www.mtasc.org/)
* Delivery: Player software: [Gnash](http://www.gnu.org/software/gnash/) (standalone or browser plugin, Linux)
_ActionScript 3_ (_[single file "applet" example](http://stackoverflow.com/questions/10243353/yet-another-local-file-access-in-actionscript-3-q-u-e-stion)_)
* Language: ActionScript 3
* Compiler: [mxmlc](http://livedocs.adobe.com/flex/3/html/compilers_14.html), part of Flex SDK ([here](http://www.adobe.com/cfusion/entitlement/index.cfm?e=flex3sdk) or [here](http://www.adobe.com/devnet/flex/flex-sdk-download.html))
* Delivery: Player software: [Lightspark](http://lightspark.github.com/) (standalone or browser plugin, Linux)
### HTML5 Canvas ###
* Language: JavaScript + library APIs
* Compiler: none
* Delivery: HTML5 Canvas-enabled web browser (`firefox`, ...)
Animation functionality in this case, as of now, seems dependent on external libraries, many of which are described in [HTML5 Canvas Vector Graphics?](http://stackoverflow.com/questions/4340040/html5-canvas-vector-graphics); see also:
* [10 Super JavaScript Animation Frameworks | jQuery4u](http://www.jquery4u.com/animation/10-super-javascript-animation-frameworks/) (Jan 2012)

* [16 Impressive Flash-Like Javascript Animation Inspirations, Tutorials and Plugins | Queness](http://www.queness.com/post/456/16-impressive-flash-like-javascript-animation-inspirations-tutorials-and-plugins) (Jul 2009)
* [10 Impressive JavaScript Animation Frameworks](http://sixrevisions.com/javascript/10-impressive-javascript-animation-frameworks/) (Jun 2009)
(<sub>"<code>N __ JavaScript Animation __</code>" is now a meme, apparently `:)`</sub>)
Typical JavaScript libraries mentioned in this context are:
* Processing.js
* Raphaël
* Cake
* The Burst Engine
------
Basically, I find **ActionScript** as language very suitable for the task - I can draw vectors in code using `lineTo`; treat them as `MovieClip` objects; specify framerate and run code `onEnterFrame`, as well as have access to keyboard and mouse interaction events, and ability to run timed code (`setTimeout`, `setInterval`).
I also don't have a problem with the compilation step that generates the `swf`; besides some error checking, I think it is also responsible for the decent performance of Flash vector movies. I work on Linux, and for myself, I could relatively easily set up one of the above development environments. Problem is the delivery - if I want an open-source delivery, then I don't have cross-platform compatibility anymore (as the known open-source players seem to be Linux only).
In comparison, **JavaScript**/HTML5 Canvas would be great - since for delivery, I'd count on reproduction in established open-source web browsers. However:
* first problem is performance - most examples I've seen cause my `firefox` 13 in Ubuntu to go nearly 100% CPU on both processors, while doing relatively average animations (<sub>and I can imagine the browser choking, should I want to animate some N=250 circles in my example stated above</sub>).
* second problem is dependency on external libraries, so the concept of single source-file application becomes more complicated (<sub>Also, vendors may disappear - not sure if it's temporary, but currently I cannot access the site [hyper-metrix.com](http://hyper-metrix.com/#Burst) often given as home of the Burst JS library</sub>)
* finally - while JavaScript and ActionScript (as I understand) should follow same/similar ECMAScript specifications - some of the JavaScript libraries are not really intended for treatment of vector drawings as objects: some, instead, try to simplify access to effects like "tweening" and gradual color changes through a simple, one-liner language construct, which something I actually do _not_ need in this case (<sub>thus, finding a suitable Javascript syntax (for this particular applet use I intend) could also be a problem</sub>)
-----
So, given my notes above, what other alternatives do I have? I'm pretty sure `python` would have something - does `perl` have something too, or any other languages? Also, what would the requirements for delivery be (besides installing a given language interpreter for a given operating system), and what could one expect performance-wise (e.g. can random linear motion of 250 circles in a 640x480 px window at 45 fps, be reasonably expected on an Atom class netbook)?
Many thanks in advance for any answers,
Cheers! | 0 |

I appended jquery UIs sortable to my web-application:

Now im populating that drag and drop list in JavaScript with data from an ajax call. The list is changed by users all the time.
I try do something like this:

+data.title
+'</div>'
+'<div>'
+data.description

${"#sortable-list"}.html(htmlData);
And so on. Some of the divs also have attributes set in variables like `'id="' + data.id + '"'`
I then try to fit this string htmldata in the sortable-list. But it's getting messy pretty quick.
I tried to fit `<tables>` in it, and `<p>` with `<span>`s in. But it's still hard to get the design that I want.
Cant post images due to lack of reputation but here's the design i want:
http://img546.imageshack.us/img546/9179/48361880.gif
So how would you do this? I've been reading about templates like mustache but it don't seems to help me.
And the way I building the table with a string can't be the best way.
Any example or info on how to do this is much appreciated

Not all entries have a value like this, some just contain the first part (a UPC). I realise there are already UPC and ISRC columns provided but these aren't populated in a way that's useful to me, splitting the vendor_order_code is the only way I can do what I need to do.
Can anyone suggest the correct way of doing this? I know the below is complete nonsense, but i'm thinking something along the lines of:
'vendor_order_code' => row_data[26],
'vendor_order_code_UPC' => row_data[26].split("_")...and save just the first half regardless of whether split occurred.
'vendor_order_code_ISRC' => row_data[26].split("_")..and save just the second half if it exists

This overall results in a compact JSON (I'm serializing using JSON.NET serializer).
However when JSON containing these smaller names is passed using a POST or a PUT request to the controllers, ASP.NET MVC model binding is not able to correctly map the "EN" JSON property to "EmployeeName". It expects "EmployeeName" in JSON.
Any thoughts on how to fix this?

?> | php | image | pdf | svg | tcpdf | null | open | TCPDF: SVG image not displaying correctly
===
I have been trying to create a PDF containing a SVG image with the TCPDF Library. I wanted to have the SVG centered on a page with some text above and below it.
I have managed to get this working to a point however part of the SVG image is being cut off, it seems to have something to do with the X/Y position but I am not sure how to correct this problem.
Any help would be very much appreciated and i am interested in finding out why it is doing this rather than just displaying the full SVG image as expected.
<?php
require_once('../../TCPDF/tcpdf.php');
// Remove the default header and footer
class PDF extends TCPDF {
public function Header() {}
public function Footer() {}
}
$pdf = new PDF();

$pdf->SetFont('helvetica', 'B', 160);

The purpose of the thread is to poll movements and load images as appropriate - it loops and only quits when an atomic bool is set to true in the main thread - which is set in the objects `dealloc`.
The problem is caused by this (from the detachNewThreadSelector reference):
> The objects aTarget and anArgument are retained during the execution of the detached thread, then released
Which means my object will always have a (minimum) retain count of one - because the thread continuously polls. `dealloc` is therefore never called.
So my question is: **how can I dealloc my object taking into account the existence of the polling thread?**
The only idea I have right now is to create a destroyThread function of the object, which sets the end thread bool, which would be called from everywhere I'd *expect* the object to be destroyed. This seems error-prone, are there better solutions?

I know I can index `spec_field` and `spec_value`separately, but it will filter for specs with value more than 50, which could include fields I don't want, such as height or capacity (so searching for width > 50 will yield capacity > 50 in results).
Ideally, I'd like to assign each Specification of a Machine to its own indexed field along with its value, so that my index has field such as "height" or "weight", but the specifications are flexible, and some machines have one set of specs while another machine has a different set, so it doesn't look like it can work out.
Can it even be done with Solr?

The search is done entirely through Solr through Sunspot.
I'd like to be able to find a Machine based on its Specifications, such as find all machines with Width greater than 50.
I know I can index `spec_field` and `spec_value`separately, but it will filter for specs with value more than 50, which could include fields I don't want, such as height or capacity (so searching for width > 50 will yield capacity > 50 in results).
Ideally, I'd like to assign each Specification of a Machine to its own indexed field along with its value, so that my index has field such as "height" or "weight", but the specifications are flexible, and some machines have one set of specs while another machine has a different set, so it doesn't look like it can work out.
Can it even be done with Solr?

The next step is that I want to delegate the authentication bit to the J2EE Application Server and once authenticated the application server should pass the UserPrinciple which I will be using as context to execute the request.
I am not sure if I have asked the question correctly? I think I am mixing the WebContainer authentication with WS-Security stuff.
Can anyone please point me to the right direction with some documentation which I can refer as start-up guide.

so after selecting a suggestion, it displays lastname and firstname of player perfectly.
But one problem is created as - it creates a space in autocomplete textbox, so i need to use
backspace to remove this space so that I can search a for getting suggestions.
How can I overcome from this problem?
2. Also I am using watermark on autocomplete , it works only when I use single itemLabel like
itemLabel="#{p.lastName} otherwise it unable to display watermark in autocomplete.
3.Also when I use for no-case sensitive input so that user can search without case sensitive,
once I get any suggestions and still if try to type some keyworks for further filterations,
suggestions disappears,it works if I go for case sensitive by default way.
4. User can type players lastname or firstname , and still he needs to gets suggestion ,what modifications should I need to done in following method ?
I have stored lastname with First letter as a Capital, so I am using toUpperCase() in this way

highScoreLabel.text = [NSString stringWithFormat:@"%d",highScore];
here is my checkIfHighscore code:
-(void)checkIfHighScore
{
if(gameOverScore > highScore)
{
highScore = gameOverScore;
[[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithInt:highScore] forKey:@"HighScore"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
highScoreLabel.text = [NSString stringWithFormat:@"%d", highScore];
}
what is the problem?

var googleMap = $("#cboxLoadedContent").find("div.map")[0];
var latlng = new google.maps.LatLng(44.537266, 123.250760);
var myOptions = { zoom: 8, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP };
var map = new google.maps.Map(googleMap, myOptions);

My issue is that it doesn't load the Google map in the Colorbox. I was hoping someone can give some insight on how I can tackle this problem.
Here is a JSFilddle I created: [http://jsfiddle.net/xLGyQ/1/][2]
Many thanks,
WD

is a weird question, so Ill try to provide long explanation.
Lets say that you are running on a single core machine. And you have 2 threads, lets say classic producer consumer problem with mutexes. Now Im wondering when running on a single core machine(so 1 core no HT):
Is there a way in C++ to fuse the execution of those 2 threads into one, so that mutex can be implemented as a simple int store/load operation, instead of mutexing.
For example would this work:
producer code in the unified thread can be just putting stuff into circular buffer and consumer code will just read from the buffer if the current buffer_idx is higher than processed_idx.
I know this seems like a stupid question, but tbh a lot of embedded stuff is still 1 core.
For simplicity assume that both threads are of form
while(! shutdown)
{
//...
}
Would just putting both while bodies in a big while work as expected?

[1]: http://i.stack.imgur.com/KHYCG.png
I have designed the sorting mechanism for my site as :
Now due to change in requirement , i need to add some variables which are common to all Strategy i.e ByDate , ByConsuption , By Demand.
Also i need to modify the sorting string , based on output of a function
for example if a function returns available then,
1.SORT BY DATE DESC => sort by available desc , DATE desc
2.SORT BY DEMAND DESC => sort by available desc , DEMAND desc
Questions:
IF I have some common variables/functions how can i include at one point and still it can be accessible in all classes ?
