  • The internal implementation of R's dataset

    - by Yin Zhu
    I am trying to build a data processing program. Currently I use a double matrix to represent the data table, each row is an instance, each column represents a feature. I also have an extra vector as the target value for each instance, it is of double type for regression, it is of integer for classification. I want to make it more general. I am wondering how what kind of structure R uses to store a dataset, i.e. the internal implementation in R.

  • Detect use of older Java libraries

    - by Tony Morris
    Is there a third party library to detect the use of a Java 1.5 library when compiling with a 1.5 compiler with -source 1.4 and -target 1.4? I could use a 1.4 rt.jar in the bootclasspath however I hope there is a better way. To be used, for example, to fail the compile/build if a newer library is used.

I know you could use SoundMixer.stopAll() to stop all sound, and some how exclude the bg music, IF everything is written in the same class. But what if the sounds are called from others dynamic classes? How could I target them and exclude the bg Music?

  • ASP.net MVC How to change the Textbox Class upon validation failure?

    - by Harry
    I notice in the default MVC template project that the Account registration fields are highlighted via a class change. I can't seem to get the same behavour out of my own code (in the same project - same CSS etc) What might be stopping this from occuring? Update I believe this relates to one of my other questions Because I was having trouble with NullReferenceExceptions I have changed the Html.ValidationMessage fields to have different names than the target fields. So really, I need to resolve this question

  • Jquery Var Returned As object

    - by alex
    I'm trying to pass a variable from one function to another, but the var elmId is being returned as an object and giving an error. When we click on any of the generated divs we should be able to change the size of the div by choosing a width / height value from the drop down menus. I'm trying to pass the clicked div id which is elmId to function displayVals but it is not working. If we replace "#"+elmId in the function displayVals with the actual id of the first div created with is "#divid1" then it works. Why is the value of var elmId not being passed to displayVals <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/themes/base/jquery-ui.css" type="text/css" media="all" /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/jquery-ui.min.js" type="text/javascript"></script> <style> .aaa{width:100px; height:100px; background-color:#ccc;} button{width:100px; height:20px;} </style> <button class="idiv">div</button> <select id="width"> <option>100px</option> <option>200px</option> <option>300px</option> </select> <select id="height"> <option>100px</option> <option>200px</option> <option>300px</option> </select> <p></p> <script type="text/javascript"> var divId = 1; $("button").click(function(){ var elm = $('<div id=divid' + divId + ' class=aaa></div>'); elm.appendTo('p'); divId++; }); $("p").click(function(e){ var elmType = $(e.target)[0].nodeName, elmId = $(e.target)[0].id; return displayVals(elmId); }); function displayVals(elmId) { var iwidth = $("#width").val(); var iheight = $("#height").val(); $("#"+elmId).css({width:iwidth, height:iheight}); console.log(elmId); } $("select").change(displayVals); displayVals(); </script>

  • C# 'could not found' existing method

    - by shybovycha
    Greetings! I've been fooling around (a bit) with C# and its assemblies. And so i've found such an interesting feature as dynamic loading assemblies and invoking its class members. A bit of google and here i am, writing some kind of 'assembly explorer'. (i've used some portions of code from here, here and here and none of 'em gave any of expected results). But i've found a small bug: when i tried to invoke class method from assembly i've loaded, application raised MissingMethod exception. I'm sure DLL i'm loading contains class and method i'm tryin' to invoke (my app ensures me as well as RedGate's .NET Reflector): The main application code seems to be okay and i start thinking if i was wrong with my DLL... Ah, and i've put both of projects into one solution, but i don't think it may cause any troubles. And yes, DLL project has 'class library' target while the main application one has 'console applcation' target. So, the question is: what's wrong with 'em? Here are some source code: DLL source: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ClassLibrary1 { public class Class1 { public void Main() { System.Console.WriteLine("Hello, World!"); } } } Main application source: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Reflection; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Assembly asm = Assembly.LoadFrom(@"a\long\long\path\ClassLibrary1.dll"); try { foreach (Type t in asm.GetTypes()) { if (t.IsClass == true && t.FullName.EndsWith(".Class1")) { object obj = Activator.CreateInstance(t); object res = t.InvokeMember("Main", BindingFlags.Default | BindingFlags.InvokeMethod, null, obj, null); // Exception is risen from here } } } catch (Exception e) { System.Console.WriteLine("Error: {0}", e.Message); } System.Console.ReadKey(); } } } UPD: worked for one case - when DLL method takes no arguments: DLL class (also works if method is not static): public class Class1 { public static void Main() { System.Console.WriteLine("Hello, World!"); } } Method invoke code: object res = t.InvokeMember("Main", BindingFlags.Default | BindingFlags.InvokeMethod, null, null, null);

  • addEventListener() isn't detecting KEY_UP nor KEY_DOWN

    - by Zirenth
    My full code is import flash.events.KeyboardEvent; import flash.events.Event; //init some variables var speedX = 0; var speedY = 0; msg.visible = false; var curLevel = 2; var level = new Array(); var flagVar; var won = false; //Adding level platforms for(var i = 0; i < numChildren; i++) { if(getChildAt(i) is platform) { level.push(getChildAt(i).getRect(this)); } if(getChildAt(i) is flag) { flagVar = getChildAt(i).getRect(this); } } //Checking key presses var kUp = false; var kDown = false; var kLeft = false; var kRight = false; var kSpace = false; stage.addEventListener(KeyboardEvent.KEY_DOWN, kD); stage.addEventListener(KeyboardEvent.KEY_UP, kU); function kD(k:KeyboardEvent) { trace("Key down - " + k.keyCode); if(k.keyCode == 32) { kSpace = true; } if(k.keyCode == 37 ) { kLeft = true; } if(k.keyCode == 38) { kUp = true; } if(k.keyCode == 39) { kRight = true; } } function kU(k:KeyboardEvent) { trace("Key up - " + k.keyCode); if(k.keyCode == 32) { kSpace = false; } if(k.keyCode == 37) { kLeft = false; } if(k.keyCode == 38) { kUp = false; } if(k.keyCode == 39) { kRight = false; } } addEventListener(Event.ENTER_FRAME, loopAround); function loopAround(e:Event) { //horizontal movement if(kLeft) { speedX = -10; } else if(kRight) { speedX = 10; } else { speedX *= 0.5; } player.x += speedX; //horizontal collision checks for(var i = 0; i < level.length; i++) { if(player.getRect(this).intersects(level[i])) { if(speedX > 0) { player.x = level[i].left - player.width; } if(speedX < 0) { player.x = level[i].right; } speedX = 0; } } //vertical movement speedY += 1; player.y += speedY; var jumpable = false; //Vertical collision for(i = 0; i < level.length; i++) { if(player.getRect(this).intersects(level[i])) { if(speedY > 0) { player.y = level[i].top - player.height; speedY = 0; jumpable = true; } if(speedY < 0) { player.y = level[i].bottom; speedY *= -0.5; } } } //JUMP! if((kUp || kSpace) && jumpable) { speedY=-20; } //Moving camera and other this.x = -player.x + (stage.stageWidth/2); this.y = -player.y + (stage.stageHeight/2); msg.x = player.x - (msg.width/2); msg.y = player.y - (msg.height/2); //Checking win if(player.getRect(this).intersects(flagVar)) { msg.visible = true; won = true; } //Check for next level request if(kSpace && won) { curLevel++; gotoAndStop(curLevel); won = false; } } The section in question is //Checking key presses var kUp = false; var kDown = false; var kLeft = false; var kRight = false; var kSpace = false; stage.addEventListener(KeyboardEvent.KEY_DOWN, kD); stage.addEventListener(KeyboardEvent.KEY_UP, kU); function kD(k:KeyboardEvent) { trace("Key down - " + k.keyCode); if(k.keyCode == 32) { kSpace = true; } if(k.keyCode == 37 ) { kLeft = true; } if(k.keyCode == 38) { kUp = true; } if(k.keyCode == 39) { kRight = true; } } function kU(k:KeyboardEvent) { trace("Key up - " + k.keyCode); if(k.keyCode == 32) { kSpace = false; } if(k.keyCode == 37) { kLeft = false; } if(k.keyCode == 38) { kUp = false; } if(k.keyCode == 39) { kRight = false; } } This was working fine last night, but today I moved it to a new keyframe and now it's not working. I'm not getting any errors (even if I debug). It just won't move the character or even show up in output. I'm still quite new to as3, so I don't really know what to do. Thanks in advance. Edit: After playing with it a bit, I've found out that the reason it's not working is due to the menu. The menu has a single button and two text elements, which are fine. The code that I'm using on the menu is this: import flash.events.MouseEvent; stop(); var format:TextFormat = new TextFormat(); format.size = 26; format.bold = true; playGameButton.setStyle("textFormat", format); stage.addEventListener(MouseEvent.CLICK, playGame); function playGame(e:MouseEvent) { if(e.target.name == "playGameButton") { gotoAndStop(2); } } If I use just gotoAndStop(2); it works fine, but with everything else it just goes to the second frame, and nothing else works after that. Edit #2: I've narrowed it down even farther to the if statement itself. if(e.target == playGameButton) if(e.target.name == "playGameButton") Both of those don't work. If I just remove the if statement all together it works perfectly fine.

  • Loading images using jquery and Ajax

    - by fpz
    I have an image tag that fires a jquery function using ajax, when clicked, to download images from another source to the server. At the same time when the image is clicked it opens up a new tab and tries to load the image that is being downloaded. How can I make the link not open until the image is finished downloading to the server? This is the html <a target="_blank" href="link_to_full_image" \> <img src="link_to_thumbnail" border=0/></a>

    I have an asp.net web application that uses an unmanaged 32 bit dll that I have successfully running on my development machine, but when I use web deploy to move the code to our test server, I start seeing BadImageFormat exceptions. I set the target in visual web developer to x86 and both machines are running 64 bit os's (windows 7 and windows server 2008 r2). I'm not sure what other differences there could be causing the problem. Thanks for any help you can provide.

    I can do this: SELECT t2.value + sum(t3.value) FROM tableA t2, tableB t3 WHERE t2.somekey = t3.somekey GROUP BY t3.somekey But how to do this? UPDATE tableA t1 SET speed = ( SELECT t2.value + sum(t3.value) FROM tableA t2, tableB t3 WHERE t2.somekey = t3.somekey AND t1.somekey = t3.somekey GROUP BY t3.somekey ) ; MySQL says it's illegal since you can't specify target table t1 for update in FROM clause.

  • How are the concepts of process and threads implementated in Linux kernel?

    - by Shan
    Can any one explain how are the concepts of process and threads implemented in Linux kernel ? I am looking for an intuitive explanation with some C snippets ( and important data structures) that clearly distinguishes between the two. I am just looking for the key implementation ideas I should get hold off. Essentially, I want to understand them and implement something similar in an embedded target (not supporte by any OS) in C language.
