The Second Rule of Program Optimization (for … It makes no difference to state that something is half quicker on the off chance that it was at that point quick enough to begin. A good programmer will not be lulled into complacency by such reasoning, he will be wise to look carefully at the critical code; but only after that code has been identified. laziness.

However, when supplying the entire quote, these people sometimes actually become more convinced that what I'm doing is Premature Optimization™ and dig in and refuse to listen. Good technical design is primarily about balancing several interrelated requirements. In a few FORTRAN codes I have, the original programmers made use of boolean short circuiting.
