Dercuano

Description

Dercuano is a self-contained downloadable HTML tarball containing a book’s worth of disorganized notes I’ve made over the last few years. As an alternative option for printing and for computer systems incapable of handling a downloadable HTML tarball, I've hacked together an inferior PDF rendering of it as well, which comes to some 3900 pages, formatted for comfortable reading on hand computers. Buried among the errors, red herrings, and ratholes, there are numerous wonderful insights (perhaps even a few of them original), many fascinating facts about the world (many of which are true, and a few of which are original observations), and a wide variety of inventive ideas about what is possible and what could be done, in particular ideas about how to improve the world with new hardware and software — a few of them workable. I’ve published little of it previously.
