Why does volatile exist?
...
Some processors have floating point registers that have more than 64 bits of precision (eg. 32-bit x86 without SSE, see Peter's comment). That way, if you run several operations on double-precision numbers, you actually get a higher-precision answer than if you were to truncate each interm...
How do you trigger a block after a delay, like -performSelector:withObject:afterDelay:?

// Delay 2 seconds

Unique random string generation
...ething looking like your example, you probably want to convert it to a Base64 string:

GuidString = GuidString.Replace("=","");
GuidString = GuidString.Replace("+","");
I get rid of "=" and "+" to...
