How do you trigger a block after a delay, like -performSelector:withObject:afterDelay:?
...eter1 = 12;
float parameter2 = 144.1;
// Delay execution of my block for 10 seconds.

What must I know to use GNU Screen properly? [closed]
...
I've been using Screen for over 10 years and probably use less than half the features. So it's definitely not necessary to learn all its features right away (and I wouldn't recommend trying). My day-to-day commands are:
