Initializing a list to a known number of elements in Python [duplicate]
...ays want (currently) 4 * 24 = 96 bins. It seems natural to me (with a C / C++ / C# / etc. background) to start by initializing each bin to 0. How is this an optimization, whether premature or not?

How to detect total available/free disk space on the iPhone/iPad device?
...using NSUInteger instead of stuff like uint64_t ? We're writing Obj-C, not C++ or C. NSUInteger will give you an unsigned 64 bit integer now, but if things happen to change I imagine that Apple will update that Macro (let's say 128 bits at some point, becomes real)

Way to go from recursion to iteration
...variable a local one, and iterate instead of recurse. Here's an example in C++ (C were it not for the use of a default argument):
// tail-recursive
int factorial (int n, int acc = 1)
{
if (n == 1)
return acc;
else
return factorial(n - 1, acc * n);
}
// iterative
int factorial (int n)
