Programs are meant to be read by humans and only incidentally for computers to execute.

I define UNIX as 30 definitions of regular expressions living under one roof.

I try to learn certain areas of computer science exhaustively; then I try to digest that knowledge into a form that is accessible to people who don't have time for such study.

Meta-design is much more difficult than design; it's easier to draw something than to explain how to draw it.

I think people who write programs do have at least a glimmer of extra insight into the nature of God... because creating a program often means that you have to create a small universe

If you optimize everything, you will always be unhappy.

The psychological profiling [of a programmer] is mostly the ability to shift levels of abstraction, from low level to high level. To see something in the small and to see something in the large.
