superdan: >experience is nuttin'. it's what u learn from it.< This is generally right, exercising yourself a lot isn't enough, because you have to do it in a smart way, for example trying things a bit more difficult than the things you already know, etc. But experience can also be positive: regarding the ctips the experience of author allows him to follow rigorous and complex idioms in a very tidy way.
>u havent been around much, that's the prob.< I know the February 2002 edition of Hacker's Delight. It mostly explains numerical/bitwise things, like: - Power-of-2 boundaries and bounds checking - Rearranging bits and bytes - Integer division and division by constants - Some elementary functions on integers - Gray code - Hilbert's space-filling curve More or less none of those things are present in the ctips.
