    Ever wondered about the origins of the term "bugs" as applied to
    computer technology?  U.S. Navy Capt. Grace Murray Hopper has
    firsthand explanation.  The 74-year-old captain, who is still on
    active duty, was a pioneer in computer technology during World War
    II.  At the C.W. Post Center of Long Island University, Hopper told
    a group of Long Island public school administrators that the first
    computer "bug" was a real bug -- a moth.  At Harvard one August
    night in 1945, Hopper and her associates were working on the
    "granddaddy" of modern computers, the Mark I.  "Things were going
    badly; there was something wrong in one of the circuits of the long
    glass-enclosed computer," she said.  "Finally, someone located the
    trouble spot and, using ordinary tweezers, removed the problem, a
    two-inch moth.  From then on, when anything went wrong with a
    computer, we said it had bugs in it."  Hopper said that when the
    veracity of her story was questioned recently, "I referred them to
    my 1945 log book, now in the collection of Naval Surface Weapons
    Center, and they found the remains of that moth taped to the page
    in question."

Ha, ha, ha. Take me back to [ the alphabetic list ] [ the date-ordered list ].
