• embed multiple youtube videos to chromeless player cue

  - by Quaze

  So in the project ive been working on i use the youtube API to add a video to a chromeless player (got custom buttons, everything works no problems). It loads the youtube id which it gets from the database (Codeigniter, PHP). But what i would like to see is: instead of loading 1 video, id like to add all the videos i get from the database in the cue of that one player. So only one screen, first video retrieved from dbase gets played first, when its done second get loaded preferably also looped. Is there any way i can achieve this? My first guess would be to save the array with youtube id's somewhere and on state change (when the 'video stop'-event gets fired) load the next id from the array. Havent tried this yet because id prefer if the cue gets just gets filled on the init, so it doesnt have to load after a video has been ended. Is This possible?

• What system does before launching iPhone app's main() function?

  - by Eonil

  My app takes too much time to loading. So I put a NSLog in main() function like this to measure loading time from first: int main(int argc, char *argv[]) { NSLog(@"main"); NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; int retVal = UIApplicationMain(argc, argv, nil, nil); [pool release]; return retVal; } But, the log displayed at really later time. Default.png displayed about 5 seconds, all loading process completed in 1~2 seconds after log appeared. What's happening before executing main() function on iPhone app?

• Python - Is there a better/efficient way to find a node in tree?

  - by Sej P

  I have a node data structure defined as below and was not sure the find_matching_node method is pythonic or efficient. I am not well versed with generators but think there might be better solution using them. Any ideas? class HierarchyNode(): def __init__(self, nodeId): self.nodeId = nodeId self.children = {} # opted for dictionary to help reduce lookup time def addOrGetChild(self, childNode): return self.children.setdefault(childNode.nodeId,childNode) def find_matching_node(self, node): ''' look for the node in the immediate children of the current node. if not found recursively look for it in the children nodes until gone through all nodes ''' matching_node = self.children.get(node.nodeId) if matching_node: return matching_node else: for child in self.children.itervalues(): matching_node = child.find_matching_node(node) if matching_node: return matching_node return None

• git and local modifications

  - by user362073

  Hi I am discovering how to use git. I just made the following test: create a folder and 2 files then git init, git add ., git commit -m "initial commit" create a branch: git branch experimental, git checkout experimental then change the name of the folder and delete one of the files, then git add ., git commit -m "experimental" go back to master: git checkout master Surprise: I do not find the master as I left it; the folder has disappeared. And I have to do a git -reset --hard to find my folder. I wonder if I did something wrong or if I have not understood how git manages local changes. Thanks for your help.

• In FLEX, How can you stop ENTER Key from my Alert being caught by the control that initiated the Al

  - by WeeJavaDude

  I am having an issue where I show an AlertBox message when the user hits ENTER and the focus is in a text area. The pop up works fine, but when the user hits enter the Alert closes as expected, but the TextArea listener receives the ENTER event from the Alert and pops the dialog up again. I have tried a number of ways to catch and eat the event but so far I have not been lucky. Is there way to accomplish this? public function init():void { myTextInput.addEventListener(KeyboardEvent.KEY_UP, handleKeyStrokes); } public function handleKeyStrokes(evt:KeyboardEvent):void { if(evt.keyCode == Keyboard.ENTER) { myAlert = Alert.show("This is a test and only a test", "Title", 4, null, alertCallBack); } } <mx:TextInput id="myTextInput" left="600" top="10"> </mx:TextInput>

• Initializing and accessing a pointer from an array of pointers

  - by idealistikz

  Suppose I have the following: void **Init(int numElems) { //What is the best way to intialize 'ptrElems' to store an array of void *'s? void **ptrElems = malloc(numElems * sizeof(void *)); return ptrElems; } //What is the best way to return a pointer pointing at the index passed as a parameter? void **GetPtr(void **ptrElems, int index) { void **elem = elems + (index * sizeof(void *)); return elem; } First, what is the best way to intialize 'ptrElems' to store an array of pointers? I use malloc because assigning it to an array will not persist after the end of the function. Second, what is the best way to point to the pointer at the specified index? I tried typecasting the first line of the 'GetPtr' function to ensure proper pointer arithmetic, but I receive the warning, 'initialization from incompatible pointer type'. Is it necessary to typecast?

• Question regarding two dimensional array

  - by Sherwood Hu

  I have some problems using two dimensional array in the code and need some help. static const int PATTERNS[20][4]; static void init_PATTERN() { // problem #1 int (&patterns)[20][4] = const_cast<int[20][4]>(PATTERNS); ... } extern void UsePattern(int a, const int** patterns, int patterns_size); // problem #2 UsePattern(10, PATTERNS, sizeof(PATTERNS)/sizeof(PATTERNS[0])); in the first statement, I need to cast the const off the two dimensional array PATTERNS. The reason for this is that the init function is called only once, and in the remaining code, PATTERNS is strictly read-only. In the second statement, I need to pass PATTERNS array to the int** argument. Direct passing resulted a compile error. Thanks!

• What should I read to improve my C++ style

  - by Victor Ronin

  I was developing for quite long time already on C/C++ (mostly C, which makes style poorer). So, I know how to use it. However, quite often I stuck with style decisions like: - should I return error code here, throw exceptions, return error through a parameter - should I have all this stuff in constructor or should I create separate init function for that. and so on. Any solutions WILL work. However, each of them has cons and pros, which I know and most importantly which I don't know. It would be very nice to read something regarding overall C++ development style, coding practices and so forth. What do you recommend?

• Please clarify a few points concerning Java Servlets

  - by EugeneP

  suppose, I use Tomcat as a web container. Is it true that once all the servlets found in a web-app/WEBAPPNAME are init(IALIZED) then every change of a Servlet's property will be seen to every session. So session 1 changes a property userName of a Servlet1 from "user1" to "user2" session 1 is closed. session 2 starts. It will see "user2" as the only value of Servlet1.userName property?? Any change of a Servlet's field will be seen to all subsequent sessions? Are servlets singletons, aren't they?

• Android Source code download error

  Hi all I have followed the instructions on the Android website on how to download the latest android source code files but it gives errors when i run this command: repo init -u git://android2.git.kernel.org/platform/manifest.git It gives the following error: Getting repo ... from git://android.git.kernel.org/tools/repo.git android.git.kernel.org[0: 199.6.1.176]: errno=Connection refused android.git.kernel.org[0: 130.239.17.12]: errno=Connection refused fatal: unable to connect a socket (Connection refused) On checking forums for its resolution, i was told that port 9418 was being blocked. I use Ubuntu 10.04 and ensured that the firewall wasnt blocking the port and also enabled the port and the above IP addresses. I also spoke to the networking peeps who ensured that no traffic from the internet is being blocked. I would be glad if i could get directions on how to proceed next. Many thanks as you respond.

• Python instances and attributes: is this a bug or i got it totally wrong?

  - by Mirko Rossini

  Suppose you have something like this: class intlist: def __init__(self,l = []): self.l = l def add(self,a): self.l.append(a) def appender(a): obj = intlist() obj.add(a) print obj.l if __name__ == "__main__": for i in range(5): appender(i) A function creates an instance of intlist and calls on this fresh instance the method append on the instance attribute l. How comes the output of this code is: [0] [0, 1] [0, 1, 2] [0, 1, 2, 3] [0, 1, 2, 3, 4] ? If i switch obj = intlist() with obj = intlist(l=[]) I get the desired output [0] [1] [2] [3] [4] Why this happens? Thanks

• Proguard shrinks too much

  - by vRallev

  Since ADT 17 you can find in the gen folder a BuildConfig class with a DEBUG constant. I often use this constant in my code, since ADT changes the value automatically when you export the application. However with Proguard this doesn't work anymore. E.g. I have following snippet: if (!BuildConfig.DEBUG) { ACRA.init(this); } Proguard notices, that DEBUG is true, so it removes this snippet completely and shrinks the app. After that ADT changes DEBUG constant, but this is too late. The only solution I know is to create my own DEBUG constant and to change it manually again. But I really like the functionality of ADT. Do you know a better solution? Thanks in advance.

• Referencing other modules in atexit

  I have a function that is responsible for killing a child process when the program ends: class MySingleton: def __init__(self): import atexit atexit.register(self.stop) def stop(self): os.kill(self.sel_server_pid, signal.SIGTERM) However I get an error message when this function is called: Traceback (most recent call last): File "/usr/lib/python2.5/atexit.py", line 24, in _run_exitfuncs func(*targs, **kargs) File "/home/commando/Development/Diploma/streaminatr/stream/selenium_tests.py", line 66, in stop os.kill(self.sel_server_pid, signal.SIGTERM) AttributeError: 'NoneType' object has no attribute 'kill' Looks like the os and signal modules get unloaded before atexit is called. Re-importing them solves the problem, but this behaviour seems weird to me - these modules are imported before I register my handler, so why are they unloaded before my own exit handler runs?
