Doctor Who: Logopolis (Score 1)

This post reminded me of the last Tom Baker Dr. Who episode, in which the Doctor traveled to the planet Logopolis to fix the Chamelion circuit in the Tardis. It's basically a planet entirely populated by "humananoid" computers, who constantly calculate complex mathematical computations in a vast distributed environment. Their calculations supposedly helped to hold the framework of space/time together. The Master threw a wrench into the works by strategically killing off specific Logopolis citizens, thereby weakening the space/time continuum. Seems clear to me that either the Logopolians hadn't thought enough about error checking/correction, or that the Master truly was a master of distributed networks.
