Are you supposed to optimize by
1. understanding the algorithm and the context in which it is used,
and eventually modifying it within given limits on performance,
precision, etc., or
2. only by changing the way it is coded (which seems to be suggested
by your message) ?
In my experience there is much more to be gained from (1) than from
(2), so that is always the first thing I work on.
I've got something you work on but it would have to be treated as
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
