...nds by returning the value of method B such that method A's stack can be deallocated once the call to method B is made. MSIL code supports tail recursion explicitly, and for some algorithms this could be a important optimization to make. But since C# and VB do not generate the instructions to do th...

...nabled then whenever an object reaches retain count 0, rather than being deallocated it morphs itself into an NSZombie instance. Whenever such a zombie receives a message, it logs a warning rather than crashing or behaving in an unpredictable way. As such, you can debug subtle over-release/autorelea...

...on of the numbers, especially a range. 2) Instead of sorting the values, allocate them to buckets based on the distribution you just calculated. The number of buckets is chosen so that the computer can handle them efficiently, but should otherwise be as large as convenient. The bucket ranges shoul...

...Bounds(Rect) instead. (Do not use Canvas.getClipBounds().getHeight() as it allocates memory for a Rect.) For reasons of performance, you should allocate objects before they are used in onDraw(). As drawCenter() will be called within onDraw() the object Rect r is preallocated as a field here. I ...
