Datamation
     
        /day"t*-may"sh*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.
