In Madeleine L'Engle's 1962 young adult novel "A Wrinkle in Time," the author takes the idea of the evil supercomputer in a slightly different direction. When our heroes arrive on the shadowed planet of Camazotz, they find a world where society has been rigidly ordered and mechanized. Citizens must report to building-size computers at the planet's headquarters, CENTRAL Central Intelligence, which -- in a bizarrely prescient passage -- appears to function as a server farm. The upshot is that the machines are in turn controlled by a kind of evil systems administrator called IT, a telepathic, disembodied brain in league with the dark powers of the universe. It all makes sense now, doesn't it?
