These machines have no common sense; they have not yet learned to "think," and they do exactly as they are told, no more and no less. This fact is the hardest concept to grasp when one first tries to use a computer.

A mathematical formula should never be "owned" by anybody! Mathematics belong to God.

I have a hunch that the unknown sequences of DNA will decode into copyright notices and patent protections.

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

I'm obsessively detail-oriented.

My first program taught me a lot about the errors that I was going to be making in the future, and also about how to find errors. That's sort of the story of my life, making errors and trying to recover from them. I try to get things correct. I probably obsess about not making too many mistakes.

Premature optimization is the root of all evil.
