There’s nothing like the school of hard knocks to teach a person a thing or two, and geeks are no exception. “If you are writing a program that touches more than two persistent data stores, it is too complicated” is one such lesson, for example. “If Linux can do it, you shouldn’t” is another. Both, in fact, are words of wisdom shared in a recent post entitled “Programming things I wish I knew earlier” by programmer Ted Dziuba. Dziuba’s hard-won pearls of insight must have struck a strong chord with Linux bloggers.
