UNIX

The UNIX philosophy and culture has been really influential to my growth as a programmer.

It all boils down to KISS:

> Keep It Simple, Stupid!

Douglas McIlroy documents the philosophy in the Bell System Technical Journal as follows:

  1. Make each program do one thing well. To do a new job, build afresh rather than complicate old programs by adding new "features".
  2. Expect the output of every program to become the input to another, as yet unknown, program. Don't clutter output with extraneous information. Avoid stringently columnar or binary input formats. Don't insist on interactive input.
  3. Design and build software, even operating systems, to be tried early, ideally within weeks. Don't hesitate to throw away the clumsy parts and rebuild them.
  4. Use tools in preference to unskilled help to lighten a programming task, even if you have to detour to build the tools and expect to throw some of them out after you've finished using them.

As Eric S. Raymond puts It:

> To do the Unix philosophy right [..] you need to care. You need to play. You need to be willing to explore.
