Heath Johns explains TFTP, the Trivial File Transfer Protocol on O'Reilly. "TFTP's design is revealing the same way that a car's airbags are. As an airbag testifies to the probability and violent nature of a crash, so TFTP's design speaks to frequent and catastrophic data misadventure. It's trivialness of purpose (to move one file from one computer to another--nothing more, nothing less) makes it something like a 1950's truck engine: crack open the hood and it's still simple enough to understand in an afternoon."
