  • jQuery function only inside a specific div ID

    - by user412481
    I have the following function that I only want to run inside a specific div with the id of imgWrapper. I have tried a few things with parent but I cannot seem to figure this out. <script type="text/javascript" language="javascript"> $(document).ready( function () { $("img").each(function () { var src = $(this).attr("src"); if (src.substring(0, 1) == "/") $(this).attr("src", "http://serverName.com/" + src.substring(1)) }); } ); </script>

  • Inheritance question / problem

    - by Itsik
    I'm creating a custom Layout for android. The layout implementation is exactly the same, but once I need to extend from RelativeLayout, and once from LinearLayout. class Layout1 extends LinearLayout { // methods and fields } class Layout2 extends RelativeLayout { // the same EXACT methods and fields } How can I use inheritance to avoid DRY and implement my methods once.

  • Breadcrumb Navigation For Cocoa

    - by Till Theis
    Is there an open source implementation of a breadcrumb navigation for the Cocoa framework? Those path bars seem to gain more attraction these days (used in Transmit or Instinctiv) but the implementations I found are closed source.

  • What is your reporting tool of choice?

  • how to get started with TopCoder to update/develop algorithm skills ?

    - by KaluSingh Gabbar
    at workplace, the work I do is hardly near to challenging and doing that I think I might be loosing the skills to look at a completely new problem and think about different ideas to solve it. A friend suggested TopCoder.com to me, but looking at the overwhelming number of problems I can not decide how to get started? what I want is to sharpen my techniques ( not particular language or framework ).

  • Which conventions, events, etc. should I look into attending?

    - by perlox
    I am a student programmer and relatively new to the industry. Once I get out into the real world and have money to blow, which events/conventions/conferences/etc. should I look into attending? Which do you consider a must-attend-at-least-once-in-your-life-as-a-developer type of event? Just to clarify, any language, company, size, are acceptable. I'm mostly looking to generate a list of highly regarded conferences for a variety of different fields/interests.

  • Detecting if a file is binary or plain text?

    - by dr. evil
    How can I detect if a file is binary or a plain text? Basically my .NET app is processing batch files and extracting data however I don't want to process binary files. As a solution I'm thinking about analysing first X bytes of the file and if there are more unprintable characters than printable characters it should be binary. Is this the right way to do it? Is there nay better implementation for this task?

  • ConcurrenctBag(Of MyType) Vs List(Of MyType)

    - by Ben
    What is the advantage of using a ConcurrentBag(Of MyType) against just using a List(Of MyType)? The MSDN page on the CB (http://msdn.microsoft.com/en-us/library/dd381779(v=VS.100).aspx) states that ConcurrentBag(Of T) is a thread-safe bag implementation, optimized for scenarios where the same thread will be both producing and consuming data stored in the bag So what is the advantage? I can understand the advantage of the other collection types in the Concurrency namespace, but this one puzzled me. Thanks.

  • how to configure jetty 7 to use syslog or log4j

    - by egemen ozden
    I am looking for a way to direct all the jetty 7 logging to syslog. My current configuration dumps everything to JETTY_HOME/logs/.. After some initial ivestigation, it seems I should change JETTY_HOME/etc/jetty-logging.xml, but this does not look straightforward. It looks like I should create a new PrintStream implementation which sends its output to syslog and redirecting stderr and stdout to that class in jetty-logging.xml. any easier way to do that or to make jetty log directly to log4j ? Thanks

  • How to find same-value rectangular areas of a given size in a matrix most efficiently?

    - by neo
    My problem is very simple but I haven't found an efficient implementation yet. Suppose there is a matrix A like this: 0 0 0 0 0 0 0 4 4 2 2 2 0 0 4 4 2 2 2 0 0 0 0 2 2 2 1 1 0 0 0 0 0 1 1 Now I want to find all starting positions of rectangular areas in this matrix which have a given size. An area is a subset of A where all numbers are the same. Let's say width=2 and height=3. There are 3 areas which have this size: 2 2 2 2 0 0 2 2 2 2 0 0 2 2 2 2 0 0 The result of the function call would be a list of starting positions (x,y starting with 0) of those areas. List((2,1),(3,1),(5,0)) The following is my current implementation. "Areas" are called "surfaces" here. case class Dimension2D(width: Int, height: Int) case class Position2D(x: Int, y: Int) def findFlatSurfaces(matrix: Array[Array[Int]], surfaceSize: Dimension2D): List[Position2D] = { val matrixWidth = matrix.length val matrixHeight = matrix(0).length var resultPositions: List[Position2D] = Nil for (y <- 0 to matrixHeight - surfaceSize.height) { var x = 0 while (x <= matrixWidth - surfaceSize.width) { val topLeft = matrix(x)(y) val topRight = matrix(x + surfaceSize.width - 1)(y) val bottomLeft = matrix(x)(y + surfaceSize.height - 1) val bottomRight = matrix(x + surfaceSize.width - 1)(y + surfaceSize.height - 1) // investigate further if corners are equal if (topLeft == bottomLeft && topLeft == topRight && topLeft == bottomRight) { breakable { for (sx <- x until x + surfaceSize.width; sy <- y until y + surfaceSize.height) { if (matrix(sx)(sy) != topLeft) { x = if (x == sx) sx + 1 else sx break } } // found one! resultPositions ::= Position2D(x, y) x += 1 } } else if (topRight != bottomRight) { // can skip x a bit as there won't be a valid match in current row in this area x += surfaceSize.width } else { x += 1 } } } return resultPositions } I already tried to include some optimizations in it but I am sure that there are far better solutions. Is there a matlab function existing for it which I could port? I'm also wondering whether this problem has its own name as I didn't exactly know what to google for. Thanks for thinking about it! I'm excited to see your proposals or solutions :)

  • Does "make install", by convention, updates the targets it installs?

    - by Pavel Shved
    You usually invoke the following commands to build a ./configured product: make make install Okay, the product is in the system now. Then you change some source code files and invoke only make install. The question is, does the conventional implementation of install target requires the executables to be recompiled, or just the old ones should be copied to the appropriate system path?

  • How do machine code instructions get transferred to the CPU?

    - by user3711789
    I'm currently investigating what the runtime of different programming languages looks like behind the scenes. For a compiled language like C, people usually give the explanation of "Code is compiled to assembly which is assembled and linked into a binary executable. The executable is then loaded into memory and the CPU interprets it." My question is how does the CPU know where to look for the next instruction to execute? Is it a memory address stored in one of the registers?

  • How to resize an image smoothly (with resampling) using Windows API calls?

    - by Clay Nichols
    I need to resize images and resample them so they don't end up all jagged (I think that's called aliasing). I found some code (sorry, lost the link) that does this in pure VB6 code but it's a bit slow (2-5 seconds) and I'm displaying pictures in real time so I need something faster. I seem to recall seeing some examples of doing this with the GDI+ library. An example in VB6 would be ideal, but I can probably work with a simple example with Windows API calls in another language.

  • Create Linework/Geometry Using Text Style in AutoCAD

    - by Kratz
    I'm working in AutoCAD using the ObjectARX .Net API. Is there a way to either create text using lines/curves/polylines, or explode an existing text object into lines/ect? Prefereable I would like to be able to generate linework based on an exsiting AutoCAD text style. Edit: I was able to find the source for the TxtExp command here . However its in AutoCADs own Lisp language, and I can't make heads or tails of it.
