It is the fucking manual. A computer scientist is someone who fixes things that aren't broken. Any given program will expand to fill available memory. Any program that runs right is obsolete. Computer and car salesmen differ in that the latter know when they are lying.
Death is a nonmaskable interrupt.
I bet the human brain is a kludge. I smell a wumpus. If a program is useful, it must be changed. If a program is useless, it must be documented. If at first you don't succeed, you must be a programmer.
