  • Please explain this python behavior

    - by StackUnderflow
    class SomeClass(object): def __init__(self, key_text_pairs = None): ..... for key, text in key_text_pairs: ...... ...... x = SomeClass([1, 2, 3]) The value of key_text_pairs inside the init is None even if I pass a list as in the above statement.

  • Ruby on Rails: Find records based on a method in the model?

    - by sjsc
    I'm looking to use named_scope to find records based on a method in the model. Right now I have in my Order.rb model: def self.paid collect { |order| order if order.paid? } end # the method def paid order.payments.total >= order.total_price end That works, but I can't chain it if I have a shipped named_scope: named_scope :shipped, :conditions => "shipped is true" And I wanted to do: Order.paid.shipped which doesn't work. Any ideas?

  • iPhone - database reading method and memory leaks

    - by Do8821
    Hi, in my application, a RSS reader, I get memory leaks that I can't fix because I can't understand from where they come from.

  • Excel VBA Application.OnTime. I think its a bad idea to use this... thoughts either way?

    - by FinancialRadDeveloper
    I have a number of users I support that are asking for things to happen automatically ( well more automagically but that's another point!). One want events to happen every 120 secs ( see my other question ) and also another wants 1 thing to happen say at 5pm each business day. This has to be on the Excel sheet so therefore VBA as addins etc will be a no no, as it needs to be self contained. I have a big dislike of using Application.OnTime I think its dangerous and unreliable, what does everyone else think?

  • Object C casting

    - by ct2k7
    Hi, I'm trying to cast this statement: [self handError:noConnectionError]; basically, this statement is in a class, which is not the app delegate, but is the .m file of a view, specifically a view after uitableview, which contains its own uiviewtable. The warning that statement gives me is that the error produced may not be apparent to the UIView (view control container).

  • NSKeyedUnarchiver chokes when trying to unarchive more than one object

    - by ajduff574
    We've got a custom matrix class, and we're attempting to archive and unarchive an NSArray containing four of them. The first seems to get unarchived fine (we can see that initWithCoder is called once), but then the program simply hangs, using 100% CPU. It doesn't continue or output any errors. These are the relevant methods from the matrix class (rows, columns, and matrix are our only instance variables): -(void)encodeWithCoder:(NSCoder*) coder { float temp[rows * columns]; for(int i = 0; i < rows; i++) { for(int j = 0; j < columns; j++) { temp[columns * i + j] = matrix[i][j]; } } [coder encodeBytes:(const void *)temp length:rows*columns*sizeof(float) forKey:@"matrix"]; [coder encodeInteger:rows forKey:@"rows"]; [coder encodeInteger:columns forKey:@"columns"]; } -(id)initWithCoder:(NSCoder *) coder { if (self = [super init]) { rows = [coder decodeIntegerForKey:@"rows"]; columns = [coder decodeIntegerForKey:@"columns"]; NSUInteger * len; *len = (unsigned int)(rows * columns * sizeof(float)); float * temp = (float * )[coder decodeBytesForKey:@"matrix" returnedLength:len]; matrix = (float ** )calloc(rows, sizeof(float*)); for (int i = 0; i < rows; i++) { matrix[i] = (float*)calloc(columns, sizeof(float)); } for(int i = 0; i < rows *columns; i++) { matrix[i / columns][i % columns] = temp[i]; } } return self; } And this is really all we're trying to do: NSArray * weightMatrices = [NSArray arrayWithObjects:w1,w2,w3,w4,nil]; [NSKeyedArchiver archiveRootObject:weightMatrices toFile:@"weights.archive"]; NSArray * newWeights = [NSKeyedUnarchiver unarchiveObjectWithFile:@"weights.archive"]; What's driving us crazy is that we can archive and unarchive a single matrix just fine. We've done so (successfully) with a matrix many times larger than these four combined.

  • iPhone OS: KVO: Why is my Observer only getting notified at applicationDidfinishLaunching

    - by nickthedude
    I am basically trying to implement an achievement tracking setup in my app. I have a managedObjectModel class called StatTracker to keep track of all sorts of stats and I want my Achievement tracking class to be notified when those stats change so I can check them against a value and see if the user has earned an achievement. I've tried to impliment KVO and I think I'm pretty close to making it happen but the problem I'm running into is this: So in the appDelegate i have an Ivar for my Achievement tracker class, I attach it as an observer to a property value of my statTracker core data entity in the applicationDidFinishLaunching method. I know its making the connection because I've been able to trigger a UIAlert in my AchievementTracker instance, and I've put several log statements that should be triggered whenever the value on the StatTracker's property changes. the log statement appears only once at the application launch. I'm wondering if I'm missing something in the whole object lifecycle scheme of things, I just don't understand why the observer stops getting notified of changes after the applicationDidFinishLaunching method has run. Does it have something to do with the scope of the AchievementTracker reference or more likely the reference to my core data StatTracker is going away once that method finishes up. I guess I'm not sure the right place to place these if that is the case. Would love some help. Here is the code where I add the observer in my appDidFinishLaunching method: [[CoreDataSingleton sharedCoreDataSingleton] incrementStatTrackerStat:@"timesLaunched"]; achievementsObserver = [[AchievementTracker alloc] init]; StatTracker *object = nil; object = [[[CoreDataSingleton sharedCoreDataSingleton] getStatTracker] objectAtIndex:0]; NSLog(@"%@",[object description]); [[CoreDataSingleton sharedCoreDataSingleton] addObserver:achievementsObserver toStat:@"refreshCount"]; here is the code in my core data singleton: -(void) addObserver:(id)observer toStat:(NSString *) statToObserve { NSLog(@"observer added"); NSArray *array = [[NSArray alloc] init]; array = [self getStatTracker]; [[array objectAtIndex:0] addObserver:observer forKeyPath:statToObserve options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionOld context:NULL]; } and my AchievementTracker: - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { NSLog(@"achievemnt hit"); //NSLog("%@", [change description]); if ([keyPath isEqual:@"refreshCount"] && ((NSInteger)[change valueForKey:@"NSKeyValueObservingOptionOld"] == 60) ) { NSLog(@"achievemnt hit inside"); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"title" message:@"achievement unlocked" delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:nil]; [alert show]; } }

  • UIImageWriteToSavedPhotosAlbum showing memory leak with iPhone connected to Instruments

    - by user168739
    Hi, I'm using version 3.0.1 of the SDK. With the iPhone connected to Instruments I'm getting a memory leak when I call UIImageWriteToSavedPhotosAlbum. Below is my code: NSString *gnTmpStr = [NSString stringWithFormat:@"%d", count]; UIImage *ganTmpImage = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:gnTmpStr ofType:@"jpg"]]; // Request to save the image to camera roll UIImageWriteToSavedPhotosAlbum(ganTmpImage, self, @selector(imageSavedToPhotosAlbum:didFinishSavingWithError:contextInfo:), nil); and the selector method - (void)imageSavedToPhotosAlbum:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo { NSString *message; NSString *title; if (!error) { title = @"Wallpaper"; message = @"Wallpaper Saved"; } else { title = @"Error"; message = [error description]; } UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:message delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; } Am I forgetting to release something once the image has been saved and the selector method imageSavedToPhotosAlbum is called? Or is there a possible known issue with UIImageWriteToSavedPhotosAlbum? Here is the stack trace from Instruments: Leaked Object: GeneralBlock-3584 size: 3.50 KB 30 MyApp start 29 MyApp main /Users/user/Desktop/MyApp/main.m:14 28 UIKit UIApplicationMain 27 UIKit -[UIApplication _run] 26 GraphicsServices GSEventRunModal 25 CoreFoundation CFRunLoopRunInMode 24 CoreFoundation CFRunLoopRunSpecific 23 GraphicsServices PurpleEventCallback 22 UIKit _UIApplicationHandleEvent 21 UIKit -[UIApplication sendEvent:] 20 UIKit -[UIWindow sendEvent:] 19 UIKit -[UIWindow _sendTouchesForEvent:] 18 UIKit -[UIControl touchesEnded:withEvent:] 17 UIKit -[UIControl(Internal) _sendActionsForEvents:withEvent:] 16 UIKit -[UIControl sendAction:to:forEvent:] 15 UIKit -[UIApplication sendAction:toTarget:fromSender:forEvent:] 14 UIKit -[UIApplication sendAction:to:from:forEvent:] 13 CoreFoundation -[NSObject performSelector:withObject:withObject:] 12 UIKit -[UIBarButtonItem(Internal) _sendAction:withEvent:] 11 UIKit -[UIApplication sendAction:to:from:forEvent:] 10 CoreFoundation -[NSObject performSelector:withObject:withObject:] 9 MyApp -[FlipsideViewController svPhoto] /Users/user/Desktop/MyApp/Classes/FlipsideViewController.m:218 8 0x317fa528 7 0x317e3628 6 0x317e3730 5 0x317edda4 4 0x3180fc74 3 Foundation +[NSThread detachNewThreadSelector:toTarget:withObject:] 2 Foundation -[NSThread start] 1 libSystem.B.dylib pthread_create 0 libSystem.B.dylib malloc I did a test with a new project and only added this code below in the viewDidLoad: NSString *gnTmpStr = [NSString stringWithFormat:@"DefaultTest"]; UIImage *ganTmpImage = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:gnTmpStr ofType:@"png"]]; // Request to save the image to camera roll UIImageWriteToSavedPhotosAlbum(ganTmpImage, nil, nil, nil); The same leak shows up right after the app loads Thank you for the help.

  • WordPress: Display Online Users' Avatars

    - by Wade D Ouellet
    Hi, I'm using version 2.7.0 of this WordPress plugin to display which users are currently online (the latest version doesn't work): http://wordpress.org/extend/plugins/wp-useronline/ It's working great but I would love to be able to alter it quickly to display the users' avatars instead of their names.

    What are the best known labs for research in CG especially raytracing/rendering? I want to pursue Masters/PhD in this field and though I have been working on projects such as raytracers, it is all self-driven. What would be a good place to start, perhaps as a research intern? Also, what kind of background is expected for admissions in these programs, in terms of programming skills, formal education etc.?

  • Change table view ( style grouped ) background color ?

    - by Madhup
    Hi all, I am developing an iPad application in which I need a table view ( style grouped ) having background color as clearColor. My problem is [self.tableView setBackgroundColor:[UIColor clearColor]]; works well if the table view style is plain but when I switch to group table view the background color does not changes it stays gray in color. FYI: the contentview background color of tableviewcell also does not change. Is this a bug in iPhone-sdk or I am doing something wrong. Thanks, Madhup

    Can anyone point me to any self-contained, complete, current reference materials/projects using NHibernate in an ASP.NET MVC2 application? I have looked at Sharp Architecture, but I am not sure I need the complexity in that project. I certainly don't know enough about it to know if it is over-engineered for my purposes. I would like to see more types of implementations to gauge the various ways people have skinned this cat.

  • Java Deflater strategies - DEFAULT_STRATEGY, FILTERED and HUFFMAN_ONLY

    - by Keyur
    I'm trying to find a balance between performance and degree of compression when gzipping a Java webapp response. In looking at the Deflater class, I can set a level and a strategy. The levels are self explanatory - BEST_SPEED to BEST_COMPRESSION. I'm not sure regarding the strategies - DEFAULT_STRATEGY, FILTERED and HUFFMAN_ONLY I can make some sense from the Javadoc but I was wondering if someone had used a specific strategy in their apps and if you saw any difference in terms of performance / degree of compression. Thanks, Keyur

  • current location too slow for view

    - by Christian
    Hi, I make an App with a Map in the App and a button to change to the google.Map-App. The code for my position is: -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { float avgAccuracy = (newLocation.verticalAccuracy + newLocation.horizontalAccuracy)/2.0; if (avgAccuracy < 500) { [locationManager stopUpdatingLocation]; locationManager.delegate = nil; } storedLocation = [newLocation coordinate]; The code for the view is: - (void)viewDidLoad { [super viewDidLoad]; UIImage *image = [UIImage imageNamed: @"LogoNavBar.png"]; UIImageView *imageview = [[UIImageView alloc] initWithImage: image]; UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView: imageview]; self.navigationItem.rightBarButtonItem = button; [imageview release]; [button release]; locationManager=[[CLLocationManager alloc] init]; locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest; locationManager.distanceFilter = kCLDistanceFilterNone; [locationManager startUpdatingLocation]; mapView.showsUserLocation = YES; NSLog(@"storedLocation-latitude für MKregion: %f", storedLocation.latitude); MKCoordinateRegion region; region.center.latitude = (storedLocation.latitude + 45.58058)/2.0; region.center.longitude = (storedLocation.longitude - 0.546835)/2.0; region.span.latitudeDelta = ABS(storedLocation.latitude - 45.58058); region.span.longitudeDelta = ABS(storedLocation.longitude + 0.546835); [mapView setRegion:region animated:TRUE]; MKCoordinateRegion hotel; hotel.center.latitude = 45.58058; hotel.center.longitude = -0.546835; HotelPositionMarker* marker = [[HotelPositionMarker alloc] initWithCoordinate:hotel.center]; [mapView addAnnotation:marker]; [marker release]; } My problem: when the "viewDidLoad" start, the "storedLocation" is still 0.0000 it takes a bit longer to get the own position than to start the view. The Log for the "storedLocation" in the "viewDidLoad"-section is 0 while the Log of the "storedLocation" in the "-(IBAction)" when the map is visible contains the right values. How can I manage it to have my coordinates before the view load? I need them to center the view concerning the own position and the position given by me. MKCoordinateRegion region; region.center.latitude = (storedLocation.latitude + 45.58058)/2.0; region.center.longitude = (storedLocation.longitude - 0.546835)/2.0; region.span.latitudeDelta = ABS(storedLocation.latitude - 45.58058); region.span.longitudeDelta = ABS(storedLocation.longitude + 0.546835); [mapView setRegion:region animated:TRUE];
