(that don't neatly fit into one of the other categories)
the author's "fragmentary attempts to do philosophy", presented in a deeply idosyncratic hypertext format that i absolutely adore
finally figured out how to get to the list of all this person's textual notes, after seeing several individual notes linked to across the web. (it's the second square in the grid, the one that's a zoomed-out screenshot of a bunch of text. most of the rest of those squares go to visual artwork.)
apologies, i'm kind of tired of trying to write descriptions for random personal sites. it's very cool though, otherwise it wouldn't be on here.
"the hobby website of ian fieggen (also known as 'professor shoelace')"--indeed, the site has instructions on methods of lacing and tying shoes, as well as software and computer graphics information.
found this site through its page on pre-1950s computing; it also has info about railway signalling, among other things
blog with fiction writing, dreams, and various opinions of the author
personal wiki with pages largely on tech topics, but also on crafts, learning, household tips, and other general topics.
blog with topics including physics, cryptography, and anarchism
home of "some of [the author's] internet projects". of particular note is "how to make a complete map of every thought you think", which is like... mad science but for note-taking
paganism, alterhumanity, poetry...
lo-tech explorations, plus some small audio/video projects and a guide on simulcasting with friends
colorful site with lots of the author's personal projects; i recommend the story "gaffe: a clown goes through hell". also, the "follow me on iNaturalist" button on the front page gets me every time, not really sure why.
