I should also point out that the way I arrive at these statistics is through my possibly-less-than-optimal problem-solving technique: Whenever faced with starting a new programming task, [1] I look for a package that does exactly what I need in the Debian archive, [2] I look for a repo on GitHub with a name that suggests exactly what I want to do, then [3] I look it up in Knuth. I gather that some people think I'm skipping some steps, although they never say what they are.
