Chapter Eleven · Part III, The Rebels

The Pipe and the Kernel

Forthcoming

Ken Thompson's wife took the baby to California for three weeks in the summer of 1969, and he used the time to write an operating system on a discarded PDP-7, partly so he could play a space game. Dennis Ritchie invented C so the system could move between machines. Doug McIlroy nagged for nine years until programs could be joined like garden hose, and got his pipes in one evening. A legal settlement meant AT&T could not sell the result, so it posted the source to universities.

The idea it builds
Small programs joined by pipes, so one program's output is the next one's input, and an operating system written in a portable language.
