Datamation/day`t*-may'sh*n/ n. A magazine that many hackers assume all suits read. Used to question an unbelieved quote, as in "Did you read that in `Datamation?'" (But see below; this slur may be dated by the time you read this.) 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 for a long time after that it was much more exclusively suit-oriented and boring. Following a change of editorship in 1994, Datamation is trying for more of the technical content and irreverent humor that marked its early days.
