Example text

1 Unix has already undergone several such transformations. —Ken Thompson 1. In fact, Ethernet has already been replaced by a different technology with the same name—twice. Once when coax was replaced with twisted pair, and a second time when gigabit Ethernet came in. 3 The Case against Learning Unix Culture 5 At least one of Unix’s central technologies—the C language—has been widely naturalized elsewhere. Indeed it is now hard to imagine doing software engineering without C as a ubiquitous common language of systems programming.

This leads to... 14 Rule of Generation: Avoid hand-hacking; write programs to write programs when you can. Human beings are notoriously bad at sweating the details. Accordingly, any kind of hand-hacking of programs is a rich source of delays and errors. The simpler and more abstracted your program specification can be, the more likely it is that the human designer will have gotten it right. Generated code (at every level) is almost always cheaper and more reliable than hand-hacked. We all know this is true (it’s why we have compilers and interpreters, after all) but we often don’t think about the implications.

It’s hard to avoid programming overcomplicated monoliths if none of your programs can talk to each other. Unix tradition strongly encourages writing programs that read and write simple, textual, stream-oriented, device-independent formats. Under classic Unix, as many programs as possible are written as simple filters, which take a simple text stream on input and process it into another simple text stream on output. Despite popular mythology, this practice is favored not because Unix programmers hate graphical user interfaces.
