  • Symfony user authentication using Active Directory

    - by Radu Dragomir
    Is there a way to authenticate users in symfony apps using Active Directory? Can you please point out some documentation? edit What i need is to have a transparent login in my application. The user authenticates once at windows logon, then all applications should be accessed with the same credentials without being asked for the domain\username and password again. I tried the following in a simple php script: if (!isset($_SERVER['PHP_AUTH_USER'])) { header('WWW-Authenticate: Basic realm="my realm"'); header('HTTP/1.0 401 Unauthorized'); exit; } else { echo "<p>Hello {$_SERVER['PHP_AUTH_USER']}.</p>"; echo "<p>You entered {$_SERVER['PHP_AUTH_PW']} as your password.</p>"; } but then i get the authentication form popped up. Is there any way to pass the header the credentials used at windows logon? Thanks, Radu.

  • Proper way to return an array

    - by Ward
    Hey there, I never seem to get this right. I've got a method that returns a mutable array. What is the proper way to return the array and avoid potential memory leaks? If I plan to store the results locally inside another view controller, does that affect the way the array should be returned? Lastly, what if it's just an non-mutable array? Does that require a different technique? thanks, Howie

  • Share background view between tabs on a UITabBarController

    - by MikeQ
    Is it possible to have the same background between tabs on a UITabBarController without having to set the same background on all the views? I want to put a view in the background that periodically does a very short, non-resource intensive animation. When switching tabs, I'd like that animation to persist. I've read how to do it for UINavigationControllers, but haven't found any tips for a UITabBarController.

  • How does UIImage work in low-memory situations?

    - by kubi
    According to the UIImage documentation: In low-memory situations, image data may be purged from a UIImage object to free up memory on the system. Does anyone know how this works? It appears that this process is completely transparent and will occur in the background with no input from me, but I can't find any definitive documentation one way or the other. Second, will this data-purge occur when the image is not loaded by me? (I'm getting the image from UIImagePicker). Here's the situation: I'm taking a picture with the UIImagePickerController and and immediately taking that image and sending it to a new UIViewController for display. Sending the raw image to the new controller crashes my app with memory warnings about 30% of the time. Resizing the image takes a few moments, time that I'd rather not spend if there's a 3rd option available to me.

  • Control third check box based on the state of the first two using jquery

    - by Moj
    I have three check boxes and need to disable the third if either and/or of the other two are checked. I'm sure there's a easier way than what I have currently. It's turning into what I believe is a mess and I'm hoping that someone with more jquery knowledge can shine the light here. Here's my simple html form: <html> <head> <script type="text/javascript" src="jquery.js"></script> <script src="custom.js" type="text/javascript"></script> </head> <body> <input type="checkbox" class="class" id="1">First <input type="checkbox" class="class" id="2">Second <input type="checkbox" class="class" id="3">Third </body> </html> Here's the javascript I'm using with jquery v1.4.2 jQuery(document).ready(function() { // watches the events of all checkboxes $(":checkbox").click(function(){ if( // if both 1 and 2 are checked we don't want to enable Third until both are unchecked. (($('#1:checkbox').attr('checked'))&&($('#2:checkbox').attr('checked')))|| ((($('#1:checkbox').attr('checked'))&&($('#2:checkbox').attr('checked')))&&($('#3:checkbox').attr('disabled')))|| ((($('#1:checkbox').attr('checked'))||($('#2:checkbox').attr('checked')))&&($('#3:checkbox').attr('disabled'))) ){ // we don't want to do anything in the above events } else if( // handles the First check box (($('#1:checkbox').attr('checked'))||(!$('#1:checkbox').attr('checked')))|| // handles the Second check box (($('#2:checkbox').attr('checked'))||(!$('#2:checkbox').attr('checked'))) ){ // call the disableThird function disableThird(); } }); // handles enabling and disabling the Third checkbox function disableThird(){ var $checkbox = $('#3:checkbox'); $checkbox.attr('disabled', !$checkbox.attr('disabled')); }; }); For some reason checking #3 will disable it's self. I don't understand why. This works, but one of the requirements is that a non programmer should be able to edit and maintain this. Ideally it'd be great if he could just add new check boxes to the html and it would work. The class for these are define and as far as I know can't be changed. The last check box in the list of check boxes will disable if any of the ones above are selected. Like wise if the last check box is selected, it will disable all the ones above it. I haven't even begun writing and testing that portion as this is quickly becoming too complicated for a non programmer to handle. I myself am more of a PHP coder than a js, let alone jquery, coder. Any help would be greatly appreciated.

  • Asynchronous readback from opengl front buffer using multiple PBO's

    - by KillianDS
    I am developing an application that needs to read back the whole frame from the front buffer of an openGL application. I can hijack the application's opengl library and insert my code on swapbuffers. At the moment I am successfully using a simple but excruciating slow glReadPixels command without PBO's. Now I read about using multiple PBO's to speed things up. While I think I've found enough resources to actually program that (isn't that hard), I have some operational questions left. I would do something like this: create a series (e.g. 3) of PBO's use glReadPixels in my swapBuffers override to read data from front buffer to a PBO (should be fast and non-blocking, right?) Create a seperate thread to call glMapBufferARB, once per PBO after a glReadPixels, because this will block until the pixels are in client memory. Process the data from step 3. Now my main concern is of course in steps 2 and 3. I read about glReadPixels used on PBO's being non-blocking, will this be an issue if I issue new opengl commands after that very fast? Will those opengl commands block? Or will they continue (my guess), and if so, I guess only swapbuffers can be a problem, will this one stall or will glReadPixels from front buffer be many times faster than swapping (about each 15-30ms) or, worst case scenario, will swapbuffers be executed while glReadPixels is still reading data to the PBO? My current guess is this logic will do something like this: copy FRONT_BUFFER - generic place in VRAM, copy VRAM-RAM. But I have no idea which of those 2 is the real bottleneck and more, what the influence on the normal opengl command stream is. Then in step 3. Is it wise to do this asynchronously in a thread separated from normal opengl logic? At the moment I think not, It seems you have to restore buffer operations to normal after doing this and I can't install synchronization objects in the original code to temporarily block those. So I think my best option is to define a certain swapbuffer delay before reading them out, so e.g. calling glReadPixels on PBO i%3 and glMapBufferARB on PBO (i+2)%3 in the same thread, resulting in a delay of 2 frames. Also, when I call glMapBufferARB to use data in client memory, will this be the bottleneck or will glReadPixels (asynchronously) be the bottleneck? And finally, if you have some better ideas to speed up frame readback from GPU in opengl, please tell me, because this is a painful bottleneck in my current system. I hope my question is clear enough, I know the answer will probably also be somewhere on the internet but I mostly came up with results that used PBO's to keep buffers in video memory and do processing there. I really need to read back the front buffer to RAM and I do not find any clear explanations about performance in that case (which I need, I cannot rely on "it's faster", I need to explain why it's faster). Thank you

  • Short Python alphanumeric hash with minimal collisions

    - by ensnare
    I'd like to set non-integer primary keys for a table using some kind of hash function. md5() seems to be kind of long (32-characters). What are some alternative hash functions that perhaps use every letter in the alphabet as well as integers that are perhaps shorter in string length and have low collision rates? Thanks!

  • Setting java.awt.headless=true programmatically

    - by reto
    I'm trying to set java.awt.headless=true during the application startup but it appears like I'm to late and the non-headless mode is already started: static { System.setProperty("java.awt.headless", "true"); /* java.awt.GraphicsEnvironment.isHeadless() returns false */ } Is there another way set headless=true beside -Djava.awt.headless? I would prefer to not configure anything on the console. Thanks! Reto

  • ASP.NET MVC - Localization route

    - by ropstah
    Hi, i'd like to create localized URL's for my site. They should obviously point to the same controller actions, but I want the first routevalues to -always- be the location/language specification. Is this possible? http://www.website.com/en/us/controller/action http://www.website.com/en/gb/controller/action I understand it can be done by defining {language} and {location} in every route, but i'm looking for a slick, non-hacky solution.

  • Psuedo LRU tree algorithm.

    - by patros
    A lot of descriptions of Pseudo LRU algorithms involve using a binary search tree, and setting flags to "point away" from the node you're searching for every time you access the tree. This leads to a reasonable approximation of LRU. However, it seems from the descriptions that all of the nodes deemed LRU would be leaf nodes. Is there a pseudo-LRU algorithm that deals with a static tree that will still perform reasonably well, while determining that non-leaf nodes are suitable LRU candidates?

  • C++ template-function -> passing a template-class as template-argument

    - by SeMa
    Hello, i try to make intensive use of templates to wrap a factory class: The wrapping class (i.e. classA) gets the wrapped class (i.e. classB) via an template-argument to provide 'pluggability'. Additionally i have to provide an inner-class (innerA) that inherits from the wrapped inner-class (innerB). The problem is the following error-message of the g++ "gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)": sebastian@tecuhtli:~/Development/cppExercises/functionTemplate$ g++ -o test test.cpp test.cpp: In static member function ‘static classA<A>::innerA<iB>* classA<A>::createInnerAs(iB&) [with iB = int, A = classB]’: test.cpp:39: instantiated from here test.cpp:32: error: dependent-name ‘classA::innerA<>’ is parsed as a non-type, but instantiation yields a type test.cpp:32: note: say ‘typename classA::innerA<>’ if a type is meant As you can see in the definition of method createInnerBs, i intend to pass a non-type argument. So the use of typename is wrong! The code of test.cpp is below: class classB{ public: template < class iB> class innerB{ iB& ib; innerB(iB& b) :ib(b){} }; template<template <class> class classShell, class iB> static classShell<iB>* createInnerBs(iB& b){ // this function creates instances of innerB and its subclasses, // because B holds a certain allocator return new classShell<iB>(b); } }; template<class A> class classA{ // intention of this class is meant to be a pluggable interface // using templates for compile-time checking public: template <class iB> class innerA: A::template innerB<iB>{ innerA(iB& b) :A::template innerB<iB>(b){} }; template<class iB> static inline innerA<iB>* createInnerAs(iB& b){ return A::createInnerBs<classA<A>::template innerA<> >(b); // line 32: error occurs here } }; typedef classA<classB> usable; int main (int argc, char* argv[]){ int a = 5; usable::innerA<int>* myVar = usable::createInnerAs(a); return 0; } Please help me, i have been faced to this problem for several days. Is it just impossible, what i'm trying to do? Or did i forgot something? Thanks, Sebastian

  • Basic OpenGL ES2 (iPhone Simulator) question...

    - by David
    Hi! I'm trying to modify the fragment shader which is part of the standard iPhone/XCode OpenGL ES template. I want to make it so that every other row of pixels is transparent. I have this code so far: varying lowp vec4 colorVarying; void main() { gl_FragColor = vec4(colorVarying.x, colorVarying.y, colorVarying.z, floor(mod(gl_FragCoord.y, 2.0))); } But when I compile and run I still get the same square moving up and down with no other effects. What am I doing wrong here? I'm a complete n00b at Glsl - I'm trying to teach myself the very basics. (starting with this tutorial - http://www.mobileorchard.com/getting-started-with-opengl-es-20-on-the-iphone-3gs/) Please help! Thanks! David :)

  • Can Rational Team Concert and IntelliJ coexist?

    - by Paul McKenzie
    I am a long time intellij user. The company where I work is likely to introduce Rational Team Concert to our department shortly. I went to the RTC demo and it looks like a reasonable product, built around Eclipse, but I would rather not give up using IntelliJ. Does anyone have experience of using non-eclipse IDEs with RTC?

  • Fast, lightweight HTML parser for C++

    - by Jen
    I'm looking for a fast, lightweight open-source HTML parser -- something along the lines of a non-validating SAX parser (except, of course, for HTML). The answers to this question cover a parser that generates a DOM (don't want that), and these answers suggest conforming the HTML to XML before sending it to Xerxes (can't do that in my case). Any suggestions?

  • Marshal generic return types for com interop

    - by Israel Chen
    Is it possible to Marshal a generic return type as non-generic for COM interop? Let's say I have the following class: [ComVisible(true)] public class Foo { public IEnumerable GetStr() // Generic return type { yield break; } } I know that IEnumerable implements IEnumerable. Can I force tlbexp.exe (via return: attribute or some other way) to expose GetStr() method as a method returning IEnumerbale?

  • How to cache method results in .Net

  • What are the disadvantages to declaring Scala case classes?

    - by Graham Lea
    If you're writing code that's using lots of beautiful, immutable data structures, case classes appear to be a godsend, giving you all of the following for free with just one keyword: Everything immutable by default Getters automatically defined Decent toString() implementation Compliant equals() and hashCode() Companion object with unapply() method for matching But what are the disadvantages of defining an immutable data structure as a case class? What restrictions does it place on the class or its clients? Are there situations where you should prefer a non-case class?

  • Comparing (similar) images with Python/PIL

    - by Attila Oláh
    I'm trying to calculate the similarity (read: Levenshtein distance) of two images, using Python 2.6 and PIL. I plan to use the python-levenshtein library for fast comparison. Main question: What is a good strategy for comparing images? My idea is something like: Convert to RGB (transparent - white) (or maybe convert to monochrome?) Scale up the smaller one to the larger one's size Convert each channel (= the only channel, if converted to monochrome) to a sequence (item value = color value of the pixel) Calculate the Levenshtein distance between the two sequences Of course, this will not handle cases like mirrored images, cropped images, etc. But for basic comparison, this should be useful. Is there a better strategy documented somewhere?

  • How does one build Mono with only the ECMA covered parts?

    - by Zifre
    I'm trying to figure out how to build Mono without the patented, non ECMA components, such as Winforms. Miguel de Icaza said that Mono would be split in two, so that we could build only the parts under Microsoft's Community Promise. It doesn't seem like this has happened yet. Is there any way to do this yet?
