Why start an ArrayList with an initial capacity?
... bound). It copies s + s*1.5 + s*1.5^2 + ... + s*1.5^m (such that s*1.5^m < n < s*1.5^(m+1)) elements in total. I'm no good at sums so I can't give you the precise math off the top of my head (for resizing factor 2, it's 2n, so it may be 1.5n give or take a small constant), but it doesn't take...

POSIX workaround:

How to detect when cancel is clicked on file input?
...s (a definite perk if you're using a visual workaround for the crappy default input type='file'). After that, you just need to figure out if the input value changed.

Does C++ support 'finally' blocks? (And what's this 'RAII' I keep hearing about?)
...sed because the destructor for the RAII-managed class gets called as a result. This means that when you use RAII for all members in a class that manage resources, you can get away with using a very simple, maybe even the default, destructor for the owner class since it doesn't need to manually mana...
