Knuth, Donald Ervin : Java Glossary

Another name for God. Knuth has been around longer though. His series of books on algorithms and computing written back in the 1960s are still definitive. Every time I invented an incredible new algorithm, someone would point out the idea was old hat, described in a footnote somewhere in Knuth. I did finally figure out a way of doing multiprecision divide a little faster than his algorithm.

Knuth’s Nostrum

Premature optimisation is the root of all evil.
~ Donald Ervin Knuth (born: 1938-01-10 age: 74)

The problem is fussing over fine detail to optimise wastes time and obscures the algorithm. Optimisation should be confined to choosing a good algorithm on the first pass. Only after the code is working should you fret over optimisation. Then, only if it needs it, determine the bottlenecks by measurement and fix only those.

Don’t do optimisations the compiler will do for you. That just clutters your code.

People often misapply the nostrum to imply that optimisation itself is evil. Only premature optimisation is.
