I recently added Katex support to zarch. It turned out to be extremely slow so I finally got around to improve its performance a little. If you're using my static site generator, make sure to upgrade and run
zarchitect u -r once on each project to normalize the build directories.
This probably isn't a common problem these days, but I've been accumulating a lot of paper over the years and thought it may not be a bad idea to begin storing my notes digitally. I had been pondering for a while whether I should publish them here and ended up deciding that it can't hurt. The materials section is quite barren as of yet but that's likely going to change in the future.
