Perl is essentially a standard on UNIX. In particular, there's a Perl interpreter backed with OpenBSD's base installation[0]. If you avoid recent features (you wouldn't be missing too much), then your Perl code should run wit

I think it should be appreciated in context: it's a good way to teach both awk(1) and make(1) to someone new to UNIX. It also demonstrates how to use awk(1) for prototyping, which IMO is a good programming habit to "develop":

It's definitely a core issue in all those discussions; such a notion, and others like "first cause", "good/bad", "free will", etc. are subtle and rarely come without more or less hidden assumptions. F

In case this is of interest, and unknown, there's an aesthetically pleasant digitization of Euclid's elements[0]. But I'm not sure whether it's best for studying: usually, actively engaging with the material is key (e.g.

I guess we can put things this way: the closer the codebase is to a collection of uncorrelated chunks, the more one can read it "systematically". OTOH, the more the dependencies between the various chunks, the more useful/eff

I think that some codebases can lend themselves to be read more than others. Consider for example GNU cat[0] vs. Plan9's[1], from which one can infer the overall readability of the two projects. In particular, codebases who are compose

A good option is to start by precisely copying simple drawings: while (precise) copy is of little to no artistic value, it's immensely useful to learn the craft. For a beginner, I would recommend a two-fold plan: 1) spend 80% of yo
