Datamation /day`t*-may'sh*n/ n. A magazine that many hackers assume all {suit}s read. Used to question an unbelieved quote, as in "Did you read that in "Datamation?"" It used to publish something hackishly funny every once in a while, like the original paper on {COME FROM} in 1973, and Ed Post's "Real Programmers Don't Use Pascal" ten years later, but it has since become much more exclusively {suit}-oriented and boring.
