Dernocua

Dernocua is my notebook from 02021. It’s the sequel to Dercuano and Derctuo. It contains about 410000 words, about 1100 pages, in 267 notes on various different topics: programming, machining, electronics, digital fabrication, math, physics, economics, history, and so on. These are mostly notes I made while I was figuring things out, so they have a lot of errors in them because of things I understood incorrectly, and many of them are incomplete.

Dernocua’s canonical form is [a downloadable tarball of HTML files][tarball]. For computers that can’t handle tarballs of HTML, I’ve also hacked together [an inferior PDF rendering of it][pdf], formatted for comfortable reading on small screens like those on hand computers. (In particular, a lot of the Unicode-art stuff is screwed up in the PDF, and so are tables.) Errata will be published at the GitLab repository.
