bmac's Journal: 1st Law of Computer Programming

"Any design that does not contain contradictory specs can be implemented perfectly (meaning without bugs)."

First off, if you don't believe this, don't even bother. And this doesn't pertain just to programming.

Second, contradictory specs can be irrational timing requirements or logical inconsistencies. Even most relatively competant PHB's can be coaxed into asking for a contradiction-free design due to the fact that most business logic is free of such, seeing as how most of it (that I've ever dealt with) was at one time implemented by human beings.
