When a professor insists computer science is X but not Y, have compassion for his graduate students.

In computing, turning the obvious into the useful is a living definition of the word "frustration".

When someone says, "I want a programming language in which I need only say what I want done," give him a lollipop.

There is no such thing as a free variable.

A language that doesn't affect the way you think about programming is not worth knowing.

Dealing with failure is easy: Work hard to improve. Success is also easy to handle: You've solved the wrong problem. Work hard to improve.

Programmers are not to be measured by their ingenuity and their logic but by the completeness of their case analysis.
