  • Unified Parallel C - examples and list of extensions

    - by osgx
    Hello Where can I find examples of code, written in "Unified Parallel C"? I also interested in normative documents about this language (standards, reference manuals, online-accessible books and courses). What extensions were added to C to get UPC? Is this dialect alive or dead?

  • Where did the name `atoi` come from?

    - by Earlz
    Ok I've been curious about this for a while. In the C language where did they come up with the name atoi for converting a string to an integer? The only thing I can think of is Array To Integer for an acronym but that doesn't really make sense.

  • Is there a library / api for reading the contents of a .hlp help file?

    - by boccato
    I have a help file for my program and was asked to add a description of the menus in a toolbar as the user browses them. So I thought I could just use the beginning of the menu's description of the help but just cant find how to access the contents of it. I saw WinHelp has a macro language, so I figured maybe through this, but I couldnt find any references on this around. Anybody now some pointers or examples of hot to do this?

  • How do I execute an action in drupal after each time a node is saved?

    - by ford
    I'm developing an Action in Drupal which is supposed to activate after saving a node, exporting content to XML (which includes data from the node that was just saved), using the "Trigger: After saving an updated post" trigger. Unfortunately this action actually happens right before the information from the recently saved post is saved to the database. ie. when looking at the XML later, I find that the most recent change I made was not included. Saving after editing a different node will restore the previously missing data. How can I get my action to fire after the saving process is complete?

  • do you call them functions, procedures or methods?

    - by lowlyintern
    consider a standard c# 'function' public void foo() { //some code } In c or c++ this is called a 'function' - even if taking no parameters and returning no value. In another language maybe it would be a 'procedure'. In object orientation speak it would be called a 'method' if a class member. What would be the correct term to use in c#?

  • svn update overwrite local copy - can I retrieve local copy?

    - by Myx
    Hi: So I was editing a file on my local machine and I was ready to commit to the repository except that instead of running the svn commit, I ran svn update. Is there any way I can retrieve the changes that I had? I was working on a tex file in vim and I had closed the file before running svn update. Thanks. EDIT: I'm sorry - I completely was worried for nothing (project deadline in 30 mins and I thought I deleted all my changes). I realize that when I run svn update, it doesn't rewrite the local changes but tries to merge the files if there are no conflicts. Can someone tell me how to close or remove this post? Thanks.

  • PHP debugging or performance Hook

    - by Joshua
    In an interpreted language like PHP it is possible in theory to set up some sort of callback function that would be run indiscriminately after every line of code. I am wondering if such a thing exists in PHP or if such a thing could be accomplished in any way? Such a feature could be useful for diagnostics or performance tests. Does anyone know of such a mechanism in PHP?

  • C# Generic Generics (A Serious Question)

    - by tahirhassan
    In C# I am trying to write code where I would be creating a Func delegate which is in itself generic. For example the following (non-Generic) delegate is returning an arbitrary string: Func<string> getString = () => "Hello!"; I on the other hand want to create a generic which acts similarly to generic methods. For example if I want a generic Func to return default(T) for a type T. I would imagine that I write code as follows: Func<T><T> getDefaultObject = <T>() => default(T); Then I would use it as getDefaultObject<string>() which would return null and if I were to write getDefaultObject<int>() would return 0. This question is not merely an academic excercise. I have found numerous places where I could have used this but I cannot get the syntax right. Is this possible? Are there any libraries which provide this sort of functionality?

  • How to merge multiple arrays in pairs

    - by user3688059
    I have a problem with "pairing" arrays into one (by index). Here is an example: INPUT: inputArray = [ [0, 1, 2, 3, 4], [2, 3, 5, 7, 8], [9, 6, 1] ] OUTPUT: outputArray = [ [0,2,9], [1,3,6], [2,5,1], [3,7,chooseRandom()], [4,8,chooseRandom()]] Questions: 1) How to avoid out of range problem 2) How to write chooseRandom() to choose N neighbour I'm using python but feel free to share your thoughts in any language.

  • Shadowbox + jQuery not working - No errors.

    - by Shelton
    First, apologies. I'm a js newb. I'm attempting to trigger a shadowbox with the load of a specific page - a "pop-up" if you will. Nothing happens and according to firebug, there are no errors to report. I should note that this is wordpress, so I'm using the default jQuery call and also shadowbox rolled into a WP plug-in. Shadowbox does work properly in other areas of the site, as do jQuery functions. noConflict() is used because WP also loads prototype by default, which conflicts with the jQuery dollar sign. var $j = jQuery.noConflict(); $j(function(){ //Set cookie $j.cookie('padpop_viewed',true); // open a welcome message as soon as the window loads $j(function() { Shadowbox.open({ content: '<div width="600" height="460" style="margin:auto;"><a href="<?php bloginfo('url');?>"/products/"><img src="<?php bloginfo('template_url');?>/images/ipad-pop.jpg" width="600" height="460" alt="Redacted"/></a></div>', player: "html", height: "470", width: "610" }); }); }); Any help here would be greatly appreciated as I have spent hours consulting the documentation of each aspect of this. Thanks, S.

  • What tools do people use to make programming tutorial videos?

    - by Pure.Krome
    Hi folks, I'm wanting to make some yee-run-o-the-mill tutorial video's about some programming concepts and stuff i've been doing. Nothing special ... lots of peeps been doing it. What tools are people using to record and edit these videos? What resolutions / fonts / sizes do people generally use/set? The only tool I've had experience with is Camtasia - and i didn't mind it. But i've seen vid's (or live demo's) where people zoom in to code sections.. how do they do that? For final editing, do most people just do some simple power point presentation with some video snippets mashed in. cheers!

  • Use the right tool for the job: embedded programming

    - by EmbeddedProg
    I'm interested in programming languages well suited for embedded programming. In particular: Is it possible to program embedded systems in C++? Or is it better to use pure C? Or is C++ OK only if some features of the language (e.g. RTTI, exceptions and templates) are excluded? What about Java in this domain? Thanks.

    - by StackedCrooked
    Has anyone actually used Wt? Did it work well? Did you experience certain limitations? Or advantages? Note: Please avoid the discussion of whether C++ is suited to be a web development language. I just want to give Wt a try because it seems like a fun thing to do.

  • Lightweight open source CMS - current situation

    - by patrikas
    Hello, It happened that I need to pick up PHP based open source CMS. I did a small research and found many candidates. CMS made simple seems to be right choice, but I am not sure what's the current state, I know it was widely used time ago. I need it to be fully compliant with web standarts, lightweight (especially interface). It needs to be as simple as possible - basically just style and page content editing (news, maybe some image gallery) is enough. Sure content and style have to be separated from each other since content will be edited by non-programmer. One of the main goals is SEO so I'd like it to have friendly URLs. I think CMSes like Joomla, Drupal and Wordpress are too big for this project. Are there any recommendations ?

  • Server Side code Pushing Data to client Browser while current thread is busy Comet (programming)

    - by h_power11
    Hello Friends, I am writing one simple web page with bunch of textboxes and a button control. Now when user finished editing the values on this text boxes user has to click the button and this button invoke heavily process intensive algorithm on server side code based on the data received from client (Textboxes) And it could some time takes up to 30 to 45 minutes to complete the whole operation so the current thread is still inside the button click event handler function. That background task only provides one event, and the web page subscribes to it to get some text data after each stage of processing I was wandering if there is any way I can keep user up-to-date with what is the current progress on that background task. I have div element to print the current status information So I am looking for some sort of reverse mechanism then "get" and "post". I have read some articles on the Comet (programming) but I can't find any easy or definitive answer Thanks in advance

  • python-like Java IO library?

    - by drozzy
    Java is not my main programming language so I might be asking the obvious. But is there a simple file-handling library in Java, like in python? For example I just want to say: File f = Open('file.txt', 'w') for(String line:f){ //do something with the line from file } Thanks!
