I have always been fascinated with the Unix Philosophy: +++ Make each program do one thing well. To do a new job, build afresh rather than complicate old programs by adding new "features". 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. 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. 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. +++ Creating small, simple, and yet useful programs is somewhat a lost art in this day an age, but every so often someone comes up with a new idea on how to make a single task easier, by creating a small tool for it. This site is for all those tools: they run (mostly) from the command line, and that can be combined together to do amazing things.
