Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live. -- Martin Golding

It is practically impossible to teach good programming style to students that have had prior exposure to BASIC. As potential programmers, they are mentally mutilated beyond hope of regeneration. -- E. W. Dijkstra

Don't have good ideas if you aren't willing to be responsible for them. -- Alan Perlis

There is only one way to avoid criticism: do nothing, say nothing, and be nothing. –Aristotle
