My experience working with glass is that you _don't_ want it cooled quickly. It will shatter or get internal stresses that cause it to shatter later. You anneal it in a slowly cooling oven over time. Some steels and brass can be annealed slowly and that heat could, I suppose, be captured. Tempering probably not.

> Still, even somewhat lower grade heat can be upgraded back to high grade heat with high temperature heat pumps.

Which requires energy and incurs losses. If you have energy, assuming electricity, that's cheap enough to scavenge low-level waste heat you probably don't need to recapture the heat.

Have you worked in any industrial or craft setting involving molten glass or metal? Walked around a workshop? There's no way the heat is going back into the process.

This made me laugh. In college in the late 80's I repaired a roommate's not-quite vintage C64 fastloader cartridge with a bad wire bodge using a lighter and the tine of a dining hall fork...

+1. This game was adorable and relaxing from beginning to end.

Awk is older and as a part of POSIX the version found on unix-like environments will be (outside of extensions) compatible with others. If one or one without the extensions you want isn't present you can choose an implementation, even one in Go and it'll work.

Perl, and I've been writing Perl since Perl4, doesn't have those characteristics. It's a much more powerful language that has changed over the years and it is not always present by default on a unix-like system. Because the maintainers value backward compatibility, even scripts written on Perl5.005 have a fair chance of working on a modern version but it's not assumed (and you shouldn't assume anything about modules). Because Awk is fossilized, you can assume that.

- Awk is on more systems than Perl

- Awk has more implementations than Perl

Given the assumptions, inaccuracies, and mistakes I've seen in some Haynes and Chilton manuals they'll probably fuck up with them. Factory manuals are usually worth the price (Honda's are, KTM's not so much).

I only dally with Lisp(s) but probably not, I'd reach for a library in quicklisp.

However, in Janet (https://janet-lang.org/) there's a PEG parser and I wrote a JSON parser for fun in 134 lines that passes most of the test suite by Nicolas Seriot.

So I'd say it's reasonably easy for a better-skilled programmer than I am.
