this is where the source and some of the finished products for this presentation exist.
it’s not clear to me the build process would work on anyone else’s
machine. but, if so, make is run on the source files on a
developer’s machine, and the resulting .html and .pdf files (along
with a few others), in ./artefacts/ are added to the repository and
(when git push is executed) uploaded to the github repository for
access.
the beamer slides for the presentation are here (html). a plain text file, “suitable for experimentation” in Emacs, is here; an HTML version of that file is here.
