“The computer programmer is a creator of universes for which he alone is responsible. Universes of virtually unlimited complexity can be created in the form of computer programs.”

Joseph Weizenbaum

“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.”

Donald E. Knuth
