  • Creating a Virtual Webcam Device for OS X

    - by andsve
    I am looking for a solution to create a "virtual" webcam device under OS X (that acts just as a normal hardware webcam, but the application has full control over what to output). I'm fairly experienced with C++, but not so much with Objective-C and OSX/Cocoa programming. Anyone that can point me in the right direction, where to look and what I should be looking for? I've searched, but most of the results seems to focus on Windows and DirectX. Thanks!

  • How can I stop cURL from outputting the contents of the page it loads into the browser?

    - by Rob
    I currently use curl_multi_* to connect to a few sites. Its only sending a few $_GET variables to start a script, but it outputs the html from the sites to the browser. I want to stop this. I already use a short timeout, but sometimes the scripts start fast, and I don't want to set the timeout any lower, in case it causes it not to connect. So how can I stop the output to the browser from cURL?

  • Where can I find a library that parses source code and is able to extract the scope of where your cursor is currently in the code?

    - by Anthony
    In SublimeText(2), when you press [ctrl + shift + p] (mac osx) you are shown a scope of where your caret/cursor is in the source code at the given moment e.g.: entity.name.tag.inline.any.html meta.tag.inline.any.html text.html.basic I am curious about what library or script is used to parse the document/file and create that scope string. A sidenote: Typing view.syntax_name(view.sel()[0].b) into Sublime's console will output the scope as well.

  • Is there anything like deal() for normal MATLAB arrays?

    - by jjkparker
    When dealing with cell arrays, I can use the deal() function to assign cells to output variables, such as: [a, b, c] = deal(myCell{:}); or just: [a, b, c] = myCell{:}; I would like to do the same thing for a simple array, such as: myArray = [1, 2, 3]; [a, b, c] = deal(myArray(:)); But this doesn't work. What's the alternative?

    I need to get a path to the GIT on Max OS X 10.6 using Python 2.6.1 into script variables. I use this code for that: r = subprocess.Popen(shlex.split("which git"), stdout=subprocess.PIPE) print r.stdout.read() but the problem is that output is empty (I tried stderr too). It works fine with another commands such as pwd or ls. Can anyone help me with that?

In addition, I'd like to have the dependencies present beside my module. No matter how I twist IntelliJ's "build jar" process, the output of my module appears empty (besides a META-INF file).

  • How to strip specific contents of a String in Java

    - by user2974877
    So I have a string, and I want to strip out some parts of it using, for example, the firt and last characters of the "interesting" part. String dirty = "$!$!%!%$something interesting&!!$!%$something interesting2"; And the output something like: String clean = "something interesting:something interesting2"; Note: The code needs to work without knowing the random part, changing everytime the program runs. I researched and only found code that does it, but only knowing the random segment.
