[ "simulating rolling 2 dice in Python", "I have been asked to simulate rolling two fair dice with sides 1-6. So the possible outcomes are 2-12.\n\nmy code is as follows:\n\ndef dice(n):\n x=random.randint(1,6)\n y=random.randint(1,6)\n for i in range(n):\n z=x+y\n return z\n\n\nMy problem is that this is only returning the outcome of rolling the dice 1 time, so the outcome is always 2-12. I want it to return the sum of rolling the dice (n) times. \n\nDoes anyone have any suggestions for me?" ]

[ "Retaining delegate until it is used", "So I'm writing this API which looks something like this:\n\n @implementation TheApi\n - (ObjectLoaderCallbackDelegate *)createLoaderDelegateForCallback:(ObjectLoaderCallback)callback\n {\n ObjectLoaderCallbackDelegate *loaderDelegate = [[ObjectLoaderCallbackDelegate alloc] init];\n loaderDelegate.didLoadObject = ^(id object) {\n callback(object);\n };\n return loaderDelegate;\n }\n\n - (void)loadString:(ObjectLoaderCallback)callback\n {\n ObjectLoaderCallbackDelegate *callbackDelegate = [self createLoaderDelegateForCallback:callback];\n ObjectLoader *loader = [[ObjectLoader alloc] init];\n [loader load:@\"string\" delegate:callbackDelegate];\n }\n\n - (void)loadNumber:(ObjectLoaderCallback)callback\n {\n ObjectLoaderCallbackDelegate *callbackDelegate = [self createLoaderDelegateForCallback:callback];\n ObjectLoader *loader = [[ObjectLoader alloc] init];\n [loader load:@\"number\" delegate:callbackDelegate];\n }\n @end\n\n\nWhen I call [loader load:delegate:], it doesn't keep a strong reference to the delegate (which makes sense). But because the loader does asynchronous stuff before calling the delegate, the delegate is being released before it ever gets called, resulting in a crashed program. Here is my solution (which seems a bit dirty):\n\n @interface TheApi : NSObject\n - (void)loadString:(ObjectLoaderCallback)callback;\n - (void)loadNumber:(ObjectLoaderCallback)callback;\n - (void)runCalls;\n @end\n\n @implementation TheApi\n {\n NSMutableDictionary *loaderDelegates;\n NSMutableSet *callbacksCompleted;\n }\n\n - (TheApi *) init\n {\n self = [super init];\n if (self != nil) {\n loaderDelegates = [[NSMutableDictionary alloc] init];\n callbacksCompleted = [[NSMutableSet alloc] init];\n }\n return self;\n }\n\n - (void)runCalls\n {\n [loader runLoop];\n }\n\n - (ObjectLoaderCallbackDelegate *)createLoaderDelegateForCallback:(ObjectLoaderCallback)callback\n {\n NSNumber *delegateRefKey = [NSNumber numberWithUnsignedInt:arc4random()];\n ObjectLoaderCallbackDelegate *loaderDelegate = [[ObjectLoaderCallbackDelegate alloc] init];\n loaderDelegate.didLoadObject = ^(id object) {\n callback(object);\n [callbacksCompleted addObject:delegateRefKey];\n };\n [loaderDelegates setObject:loaderDelegate forKey:delegateRefKey];\n return loaderDelegate;\n }\n\n - (void)removeCompletedDelegates\n {\n // So we can remove items from callbacksCompleted in the loop...\n NSMutableSet *callbacksCompletedIterSet = [callbacksCompleted copy];\n\n // Remove old delegates for calls already completed which are stored\n for (id key in callbacksCompletedIterSet) {\n [loaderDelegates removeObjectForKey:key];\n [callbacksCompleted removeObject:key];\n }\n }\n\n - (void)loadString:(ObjectLoaderCallback)callback\n {\n [self removeCompletedDelegates];\n ObjectLoaderCallbackDelegate *callbackDelegate = [self createLoaderDelegateForCallback:callback];\n ObjectLoader *loader = [[ObjectLoader alloc] init];\n [loader load:@\"string\" delegate:callbackDelegate];\n }\n\n - (void)loadNumber:(ObjectLoaderCallback)callback\n {\n [self removeCompletedDelegates];\n ObjectLoaderCallbackDelegate *callbackDelegate = [self createLoaderDelegateForCallback:callback];\n ObjectLoader *loader = [[ObjectLoader alloc] init];\n [loader load:@\"number\" delegate:callbackDelegate];\n }\n @end\n\n\nSo here, I'm keeping a reference to the delegates in an instance-level dictionary where they key is unique for each API method call.\n\nSo my question is: is there a better way to do keep the delegates from being released and then freeing them after the loader calls them?" ]
