Also, this reminds me of Donald Knuth's recent interview in Peter
Seibel's "Coders At Work":

"Earlier this year I finished my section on bitwise tricks and
techniques and these are things that have been a black art in
the hacker community for years. I decided it's time to say that
there's a theory of these things that you can understand
the ideas, how they fit together. You can use them yourself with
confidence. And you can build on things and do amazing
things that last year you didn't know how to do well at all. It went
through the underground until now; it's something that we
might as well teach to people--something that deserves to be common knowledge."

I assume that refers to this:
