  • Cache Auth Tokens (or Caching HTTP headers in General) - Best Practices

    - by viatropos
    I'm using the Ruby GData Library to access Google Docs and I recently got the GData::Client::CaptchaError because I was re-logging in with every request. Reading this post, it recommends not logging in with every request, but caching the authentication token. How do I go about doing that correctly? Google says it expires every 24 hours, and it doesn't seem like I should store it in the session, so what should I do? I'm using Ruby on Rails with all this. Thanks so much

  • Encoding MP3 and adding VBR or Xing headers (with lame or another method)

    - by J. Pablo Fernández
    I'm writing a program that converts wavs to mp3s, so far, by using lame. It's generating a command line more or less like this: "c:\Program Files (x86)\Lame for Audacity\lame.exe" --preset fast medium in.wav out.mp3 The problem I'm having is that no VBR or Xing headers are written to the MP3. How can I make lame.exe write those headers? Should I use another program to write those headers (platform is Windows, .Net 3.5)? Should I use another program for MP3 encoding?

  • class header+ implementation

    - by igor
    what am I doing wrong here? I keep on getting a compilation error when I try to run this in codelab (turings craft) Instructions: Write the implementation (.cpp file) of the GasTank class of the previous exercise. The full specification of the class is: A data member named amount of type double. A constructor that no parameters. The constructor initializes the data member amount to 0. A function named addGas that accepts a parameter of type double . The value of the amount instance variable is increased by the value of the parameter. A function named useGas that accepts a parameter of type double . The value of the amount data member is decreased by the value of the parameter. A function named getGasLevel that accepts no parameters. getGasLevel returns the value of the amount data member. class GasTank{ double amount; GasTank(); void addGas(double); void useGas(double); double getGasLevel();}; GasTank::GasTank(){ amount=0;} double GasTank::addGas(double a){ amount+=a;} double GasTank::useGas(double a){ amount+=a;} double GasTank::getGasLevel(){ return amount;}

    I want to check a file has a valid IMAGE_DOS_SIGNATURE (MZ) function isMZ(FileName : String) : boolean; var Signature: Word; fexe: TFileStream; begin result:=false; try fexe := TFileStream.Create(FileName, fmOpenRead or fmShareDenyNone); fexe.ReadBuffer(Signature, SizeOf(Signature)); if Signature = $5A4D { 'MZ' } then result:=true; finally fexe.free; end; end; I know I can use some code in Windows unit to check the IMAGE_DOS_SIGNATURE.

  • how to disable web page cache throughout the servlets

    - by Kurt
    To no-cache web page, in the java controller servlet, I did somthing like this in a method: public ModelAndView home(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView mav = new ModelAndView(ViewConstants.MV_MAIN_HOME); mav.addObject("testing", "Test this string"); mav.addObject(request); response.setHeader("Cache-Control", "no-cache, no-store"); response.setHeader("Pragma", "no-cache"); response.setDateHeader("Expires", 0); return mav; } But this only works for a particular response object. I have many similar methods in a servlet. And I have many servlets too. If I want to disable cache throughout the application, what should I do? (I do not want to add above code for every single response object) Thanks in advance.

  • why do i see THROW in a C library

    - by Bhagya
    When I do: less /usr/include/stdio.h (which is only a C library - nothing to do with C++) I see __THROW after quite a few function declarations. Also, comments above a few functions say that 'This function is a possible cancellation point and therefore not marked with __THROW' What is all this for? THROW is meant to be for exception handling.. but as far as I know, C doesn't provide any support for it... Plz explain.

  • How should I detect unnecessary #include files in a large C++ project?

    - by shambolic
    I am working on a large C++ project in Visual Studio 2008, and there are a lot of files with unnecessary #include's. Sometimes the #include's are just artifacts and everything will compile fine with them removed, and in other cases classes could be forward declared and the #include could be moved to the .cpp file. Are there any good tools for detecting both of these cases?

  • - Default value of variables at the time of declaration -

    - by gotye
    Hey guys, I was wondering what was the default values of variables before I intialize them .. For example, if I do : //myClass.h BOOL myBOOL; // default value ? NSArray *myArray; // default value ? NSUInteger myInteger; // default value ? Some more examples here : //myClass.m // myArray is not initialized, only declared in .h file if ([myArray count] == 0) { // TRUE or FALSE ? // do whatever } More generally, what is returned when I do : [myObjectOnlyDeclaredAndNotInitialized myCustomFunction]; Thank you for your answers. Gotye.

  • ELMAH: Only sending specific exception type via mail

    - by Sir Code-A-Lot
    Hi, I have ELMAH set up for a webapp, logging exceptions to a SQL server. I wish to have ELMAH send me an email too, but only when a specific exception is thrown (ie. MySpecialException). ELMAH must still log all exceptions to SQL server. I know you can do it programmatically in global.asax, but I'd prefer to use web.config. So, how do I restrict ELMAH error mails to filter out everything but a specific exception type, using web.config?

  • Redirects in RoR: Which one to use?

    - by scrr
    Hello, we are making a website that takes a generated incoming link and forwards the user who is clicking on it to another website while saving a record of the action in our DB. I guess it's basically what ad-services like AdSense do. However, what is the best way to redirect the user? I think html-meta-tag-redirects are out of question. So what other options are there? head :moved_permanently, :location => "http://www.domain.com/" This one is a 301-redirect. The next one is a 302: redirect_to "http://www.domain.com" Are there any others? And which is best to use for our case? The links are highly-dynamic and change all the time. We want to make sure we don't violate any existing standards and of course we don't want search-engines to tag us as spammers (which we are not, btw). Thanks!

    - by VDVLeon
    Hi all, I use the following code to get some json data: var request = new Request.JSON( { 'url': sourceURI, 'onSuccess': onPageData } ); request.get(); Request.JSON is a class from Mootools (a javascript library). But on linux (ubuntu on firefox 3.5 and Chrome) the request always fails. So i tried to display the http request ajax is sending. (I used netcat to display it) The request is like this: OPTIONS /the+url HTTP/1.1 Host: example.com Connection: keep-alive User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/532.3 (KHTML, like Gecko) Chrome/4.0.226.0 Safari/532.3 Referer: http://example.com/ref...
