  • Static code analysis tools

    - by Anil Namde
    Whether JavaSript, C# or C++ main problem i face while reading the code is which function is called by which function. This problem is big when dealing with BIG code. Is there any static code analysis tool/technique/plugins using which a graphical representation of the code can be generated(something like below) so that reading/analyzing code becomes easy? .... --outerFuntion() ---innerFunction() ----innerFunction2() --outerFunction2() .... Please provide your inputs/opinions on this Thanks all,

  • roll out of java web start clients

    - by user271858
    We are about to roll out a client server application build with java web start. Our main server is located in a country in Europe and we will have many users downloading our client the first day from all over the world. Since the client application is quite big in MB our wan will be utilized a lot. Is there a way to cache or pre- distribute java web start clients to servers "closer" to the user (for example a local server)? Thanks.

  • Why does C# allow abstract class with no abstract members?

    - by fatcat1111
    The C# spec, section 10.1.1.1, states: An abstract class is permitted (but not required) to contain abstract members. This allows me to create classes like this: public abstract class A { public void Main() { // it's full of logic! } } This is really a concrete class; it's only abstract in so far as one can't instantiate it. If inheritors don't actually have to provide implementation, then why call it abstract?

  • OpenCV performance in different languages

    - by h0b0
    I'm doing some prototyping with OpenCV for a hobby project involving processing of real time camera data. I wonder if it is worth the effort to reimplement this in C or C++ when I have it all figured out or if no significant performance boost can be expected. The program basically chains OpenCV functions, so the main part of the work should be done in native code anyway.

  • How do I specify a project dependency with Hudson?

    - by Brett Ryan
    We have common library projects shared amongst many projects that are required to be checked out into a "Libraries" folder which a developer needs to checkout prior to opening the main project in visual studio. How I tell hudson that there is this dependency? I figured one thing I could do is setup a custom workspace and specify the location for all projects, but how do I wire up the dependency between them all? Is simply specifying "Build after other projects are built" enough?

  • How to Fix my jQuery code in IE?? Works in Firefox..

    - by scott jarvis
    I am using jQuery to show/hide a div container (#pluginOptionsContainer), and load a page (./plugin_options.php) inside it with the required POST vars sent. What POST data is sent is based on the value of a select list (#pluginDD) and the click of a button (#pluginOptionsBtn)... It works fine in Firefox, but doesn't work in IE.. The '$("#pluginOptionsContainer").load()' request never seems to finish in IE - I only see the loading message forever... bind(), empty() and append() all seem to work fine in IE.. But not load().. Here is my code: // wait for the DOM to be loaded $(document).ready(function() { // hide the plugin options $('#pluginOptionsContainer').hide(); // This is the hack for IE if ($.browser.msie) { $("#pluginDD").click(function() { this.blur(); this.focus(); }); } // set the main function $(function() { // the button shows hides the plugin options page (and its container) $("#pluginOptionsBtn") .click(function() { // show the container of the plugin options page $('#pluginOptionsContainer').empty().append('<div style="text-align:center;width:99%;">Loading...</div>'); $('#pluginOptionsContainer').toggle(); }); // set the loading message if user changes selection with either the dropdown or button $("#pluginDD,#pluginOptionsBtn").bind('change', function() { $('#pluginOptionsContainer').empty().append('<div style="text-align:center;width:99%;">Loading...</div>'); }); // then update the page when the plugin is changed when EITHER the plugin button or dropdown or clicked or changed $("#pluginDD,#pluginOptionsBtn").bind('change click', function() { // set form fields as vars in js var pid = <?=$pid;?>; var cid = <?=$contentid;?>; var pDD = $("#pluginDD").val(); // add post vars (must use JSON) to be sent into the js var 'dataString' var dataString = {plugin_options: true, pageid: pid, contentid: cid, pluginDD: pDD }; // include the plugin option page inside the container, with the required values already added into the query string $("#pluginOptionsContainer").load("/admin/inc/edit/content/plugin_options.php#pluginTop", dataString); // add this to stop page refresh return false; }); // end submit function }); // end main function }); // on DOM load Any help would be GREATLY appreciated! I hate IE!

  • Replacing deprecated <:< Manifest type witness in Scala 2.10

    - by Josh
    Can someone point me at what I should be doing under scala 2.10 in place of this deprecated type witness on Manifest? reflect.ClassManifest.singleType(foo) <:< barManifest Honestly, my goal here is just to replace it with something that doesn't raise a deprecation warning. I'm happy to use the new reflection API. Here's the code in question in context, if that's important: https://github.com/azavea/geotrellis/blob/master/src/main/scala/geotrellis/feature/op/geometry/geometry.scala#L45

  • How to convert this procedural programming to object-oriented programming?

    - by manus91
    I have a source code that is needed to be converted by creating classes, objects and methods. So far, I've just done by converting the initial main into a separate class. But I don't know what to do with constructor and which variables are supposed to be private. This is the code : import java.util.*; public class Card{ private static void shuffle(int[][] cards){ List<Integer> randoms = new ArrayList<Integer>(); Random randomizer = new Random(); for(int i = 0; i < 8;) { int r = randomizer.nextInt(8)+1; if(!randoms.contains(r)) { randoms.add(r); i++; } } List<Integer> clonedList = new ArrayList<Integer>(); clonedList.addAll(randoms); Collections.shuffle(clonedList); randoms.addAll(clonedList); Collections.shuffle(randoms); int i=0; for(int r=0; r < 4; r++){ for(int c=0; c < 4; c++){ cards[r][c] = randoms.get(i); i++; } } } public static void play() throws InterruptedException { int ans = 1; int preview; int r1,c1,r2,c2; int[][] cards = new int[4][4]; boolean[][] cardstatus = new boolean[4][4]; boolean gameover = false; int moves; Scanner input = new Scanner(System.in); do{ moves = 0; shuffle(cards); System.out.print("Enter the time(0 to 5) in seconds for the preview of the answer : "); preview = input.nextInt(); while((preview<0) || (preview>5)){ System.out.print("Invalid time!!

I fixed the buttons with the .live() method, but a sortable list for example, doesn't work. How can I somehow refresh the DOM, and let jquery know of these new added elements? Thanks!

  • Performance, serve all CSS at once, or as its needed?

    - by yaya3
    As far as I know, these days there are two main techniques used for including CSS in a website. A) Provide all the CSS used by the website in one (compressed) file B) Provide the CSS for required by the elements on the page that is currently being viewed only Positives for A: The entire CSS used on the site is cached on first visit via 1 http request Negatives for A: if it's a big file, it will take a long time to load initially Positives for B: Faster initial load time Negatives for B: More HTTP requests, more files to cache Is there anything (fundamental) that I am missing here?
