• Is there a security issue with using javascript cookies?

  - by Scarface

  Hey guys, another quick question for the experts. I have an alert box that displays updates processed in php to the user just like this site. I want to make it so that if the user closes the box, then it will not pop up for another 5 minutes (unless they check the messages then it will not pop up because the entries that cause the pop up are deleted in the database). On the close of the box I was thinking of giving the user a javascript cookie, since the alert box is done in javascript. I was wondering if this was a bad coding practice, since I am kind of unfamiliar with cookies and was warned against them before. If anyone has any advice or can recommend a better way, I would really appreciate it.

• Ridiculously Simple Erlang Question

  - by Aiden Bell

  Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and is there any guarantee of order when processing messages? ie. Received in order sent? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

• Netbeans GUI Form corrupted?

  - by hubpages-my

  I was making a java gui application through netbeans IDE. All was working fine but yesterday when I opened the form in Netbeans, it said that the form had been corrupted and it could only open that form in read-only mode. When I opened that form in read-only mode, I found that the code was incomplete as severals lines of coding wasn't there at the end. Could anybody tell me how to recover the form. The form is perfect in lookwise but the generated code is incomplete. The code is too long to write it again. The Netbeans told me to get help from http://wiki.netbeans.org/FormGuardedBlockError but I didn't find any helpful information there.

• How to programmatically blur an area in a movie (in python) ?

  - by Stefano Borini

  I have a movie, and I want to produce a new movie out of it with an area blurred (e.g. an object, a writing or a face). The area is moving, so I must have fine control of the current frame and move the position of the blur area accordingly. Blur is an option, but also a dark mask is fine too. Now, I have a question open at superuser on which software to use, but since I suspect I will have to buy adobe premiere to do something like this, and I don't want to shell out a kidney for something I have to do once, I am thinking about coding it myself in python. What are the best libraries available for this task ?

• Custom XAML property

  - by Scott Silvi

  Hey all - I've seen a library that allows me to do this inside my XAML, which sets the visibility of the control based on whether or not the user is in a role: s:Authorization.RequiresRole="Admin" Using that library with my database requires a bunch of coding that I can't really do right now. Ultimately here's what I want to know... I have received the authenticated users role from my SPROC, and its currently stored in my App.xaml.cs as a property (not necessary for the final solution, just FYI for now). I want to create a property (dependency property? attached property?) that allows me to say something very similar to what the other library has: RequiresRole="Admin", which would collapse the visibility if the user is not in the Admin role. Can anyone point me in the right direction on this? Thanks, Scott

• customisable JSLint

  - by Don

  Hi, I'm looking for a tool that checks JS code, which can be integrated into a Maven build. I need a tool that will check for errors such as use of reserved words as identifiers trailing semi-colon, e.g. var obj = { a: 1, b, 2, } JSLint seems like a perfect candidate, but the problem is that it is too strict, because it also checks for various coding patterns which are (arguably) bad style, but do not actually generate errors in a browser. Examples of such issues include Disallow ++ and -- and Allow one var statement per function If possible, I would like the errors to fail the build, and I would like the other rules to only print warnings (or disable them completely). Obviously, I need the ability to specify which of the available rules I consider errors and which I consider warnings. Thanks, Don

• TFS: Managing assembly version number?

  - by TomTom

  Hello, any good approach for managing assembly version numbers in TFS, possibly together with using the same number for the build number? I would be most interested in an approach that: Maintains the first three elements of the version Counts the rest upward for every "official" build (i.e. a build originating from certain templates only - no need to count up for something like a gated checkin, but the following regular integration build SHOULD count up. Labels the builds, so that a manual "release" build can be triggered. Any solution? How are other people handling this? Right now the (new) TFS is happily building with the same assembly version all around ;) Something coding the complete assembly version with date etc. is not acceptable - I want that number to "follow rules", and having the date in there is not one of them ;)

• How do I get started on a bigger project?

  - by Axilus

  Hey guys, Most of the time I have been programming little apps either for myself or for the benifit of learning. Now that my programming skills are considered somewhat intermediate, I was wondering how I would tackle a large programming project. Lets suppose I wanted to make an application that has a lot of features and is intended for the use of others and not just myself; how do I go about planning for such projects? Do I just jump in and start coding the thing or is there some sort of recommended process? Thanks in advance :D

• Alternatives to java on android

  - by user84584

  Hello guys, I just got myself an android phone and I'm dying to start coding on it ! However I'm not a big java fan, although I can live with that, I would like to know if there're reasonable alternatives for the android virtual machine. I've done a medium sized project using clojure, however from the reviews I read, it's very slow when running on android. How about scala ? I read that some people did experiments with it in android, is it "fast enough" ? How big is the learning curve ? Cheers, Ze Maria

• C# if statement. inner workings Q

  - by Mike Mengell

  I've just come across this code snippet in some Exchange 2010 code and I was wondering if anyone knew why the programmer has done it this way. I've never seen an If statement formatted like this. It seems so backwards there must be a good reason for it?? if (true == MsgItem.HasAttachments) { // Code } I'm assuming it might have some optimisation over the various other ways of coding the same thing; if (MsgItem.HasAttachments) { // Code } or if (MsgItem.HasAttachments == true) { // Code } Its not a big deal I'm just curious. Thanks, Mike

• Finding the angle of a fleeing dodo.

  - by donthackmyacc

  I'm coding some critter AI for a game i am working on for my Unity 3D project. I have no programming background and have been stumbling through this using tutorials and other peoples scripts. My problem is that i want my critter to run directly away from the player when the player kicks it. I need the dodo to run directly away from the player when kicked, and i dont know the math nor the syntax to calculate that angle. They are two characters moving independently through worldspace. Here is what i got so far: waypoint = (fleeWP.transform.position); transform.LookAt(Vector3(waypoint.x, transform.position.y, waypoint.z)); transform.Translate (Vector3.forward * speed * Time.deltaTime); This currently makes the critter move towards the waypoint, rather than away. I might be attacking this all wrong. Please chastise me.

• yet another confusion with multiprocessing error, 'module' object has no attribute 'f'

• Best Technologies for AJAX Web Development

  - by floatingfrisbee

  Hey Everyone, I have some experience in AJAX development, mostly on .NET and MooTools. However, I want to learn more and see what others out there thought about the various other options available. I am looking more for advise about the front end. The back end, I will most probably be coding up in .NET using c# and WCF services. Please feel free to provide me as much information as you can. Also I would appreciate any links to resources. List of Options (feel free to add) Write my own Javascript Use a frame work like MooTools, JQuery etc. Which one is better? Use Google Web Toolkit. Am I tying myself to limitations of GWT? Or are there not limitations? ASP.NET AJAX WPF (Will this run on non IE browsers?) Flash (it'll be a pain to learn action script) Thanks Jaspreet

• An analog of String.Join(string, string[]) for List<T> or other generic enumerable

  - by abatishchev

  class String contains very useful method - String.Join(string, string[]). It creates a string from an array, separating each element of array with a symbol given. But general - it doesn't add a separator after the last element! I uses it for ASP.NET coding for separating with "<br />" or Environment.NewLine. So I want to add an empty row after each row in asp:Table. What method of IEnumerable<TableRow> can I use for the same functionality?

• Sound plays multiple times at once

  - by Jr. Mathews

  I'm having trouble with sound in Flash. I may have went about coding the wrong way, because most of my codes are on frames. So, I have these two variables var outsideDay:Sound = new daysong(); var outsideNight:Sound = new nightsong(); And I want to play these songs on a specific frame. However, the sounds play sporadically, like 50 times at once. I think it's because I have other codes that link to the frames with a Enter_Frame function. How can I get the sounds to loop and not play multiple times at once?

• What do gurus say about Requirements Traceability Matrix?

  - by Jaywalker

  Our organization is at CMMI Level 2, and as part of the requirements of the level, we have to maintain an RTM which more or less contains the following entries for each requirement: Requirement Description Reference Section Functional Specification Document Reference Section Design Document Reference Section Test Cases Document Now, this might be an overkill for a small project. But more importantly, this could be a nightmare to maintain when the requirements/ features keep changing, and documents have to be constantly updated. What do the gurus say about this? Should one avoid such level of documentation or are there any tools to manage when a "change" out dates so many artifacts? And by using the term 'gurus', I am not talking of coding champs; rather people like Steve McConnel or others who have worked on commercial projects of medium to large scale. Quotes/ book references/ articles will suit me. EDIT: It's not just requirements that change. Design Document can change; well, even test cases may change.

• Is it possible to integrate NUnit with VB.net Express Edition? Which is the best way?

  - by Kico Lobo

  Hi, I'm a Java Developer wich is learning VB.net for a small project. While coding in Java, we don't have to think a lot about how to integrate our IDE with our unit test framework because most of the IDEs already area integrated. But now that I'm working on a project which the main requirement is to use VB.net Express Edition, is it possible to integrate this IDE with NUnit? How can I do that? Is there a better practice for this task? What should I do? No, we can't opt to use Visual Studio, only the Express Edition of VB.net

• Passing arguments to anonymous inner classes

  - by synic

  I'm trying to make an API library for our web services, and I'm wondering if it's possible to do something like this: abstract class UserRequest(val userId: Int) { def success(message: String) def error(error: ApiError) } api.invokeRequest(new UserRequest(121) { override def success(message: String) = { // handle success } override def error(error: ApiError) = { // handle the error } } I'm talking about passing parameters to the anonymous inner class, and also overriding the two methods. I'm extremely new to Scala, and I realize my syntax might be completely wrong. I'm just trying to come up with a good design for this library before I start coding it. I'm willing to take suggestions for this, if I'm doing it the completely wrong way, or if there's a better way. The idea is that the API will take some sort of request object, use it to make a request in a thread via http, and when the response has been made, somehow signal back to the caller if the request was a success or an error. The request/error functions have to be executed on the main thread.

• Zend Framework Autoloader question.

  - by Andre

  In zend framework I register my namespace like this (in application.php): 'autoloaderNamespaces' => array( 'Cms_' ) And after this - I'd expect that Zend would always check that path in addition to Zend and ZendX paths if unknown class is called. But for some reason this doesn't work with for example view helpers. I still have to register a separate path for my view helpers even though view helper scripts are named according to Zend coding standards and are located in: Cms/View/Helper/ And this is how I register helper path in config file: view' => array( 'charset' => 'UTF-8', 'doctype' => 'XHTML1_TRANSITIONAL', 'helperPath' => array( 'Cms_View_Helper_' => 'Cms/View/Helper' ) ), So - I'm not sure why I have to register "Cms" namespace twice first through 'autoloaderNamespaces' and then through View "helperPath"? Shouldn't Cms namespace include Cms/View/Helper namespace? can someone plz clarify this:)

• How to extract a couple marked strings from a line (python)

  - by GoJian

  My Friends, I spent quite some time on this one... but cannot yet figure out a better way to do it. I am coding in python, by the way. So, here is a line of text in a file I am working with, for example: "ref|ZP_01631227.1| 3-dehydroquinate synthase [Nodularia spumigena CCY9414]..." How can I extract the two strings "ZP_01631227.1" and "Nodularia spumigena CCY9414" from the line? The pairs of "| |" and brackets are like markers so we know we want to get the strings in between the two... I guess I can probably loop over all the characters in the line and do it the hard way. It just takes so much time... Wondering if there is a python library or other smart ways to do it nicely? Thanks to all!
