The best practice is inspired by theory.

If you optimize everything, you will always be unhappy.

The manuals we got from IBM would show examples of programs and I knew I could do a heck of a lot better than that. So I thought I might have some talent.

We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%

I decry the current tendency to seek patents on algorithms. There are better ways to earn a living than to prevent other people from making use of one's contributions to computer science.

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

It would be nice if we could design a virtual reality in Hyperbolic Space, and meet each other there.
