  • alexz I heard a story that the foo-fighters (band) got their name from the term for an unidentified flying object, or unknown enemy airplane.

    foo is used heavily as a variable or function name in computing science. this goes back to before I studied CS in the 80's.

    doing a quick search of Google books, an early use of FOO in computing goes back to 1950 to the output of a diagnostic program which would print out FIBA FOO when it ran properly. http://goo.gl/WUmgB
