* `length_terminated_strings.c` - a revolution in computer science, combining the efficient `strlen` of null-terminated strings with the... inclusion of length? of length-prefixed/fat-pointer strings. A length-terminated string has its length at the *end*, occupying 1 to 8 bytes. To find its length, simply traverse the string until the data at the end matches the length traversed so far. Yes, this implementation might slightly have a bit of undefined behaviour. * `length_terminated_strings.c` - a revolution in computer science, combining the efficient `strlen` of null-terminated strings with the... inclusion of length? of length-prefixed/fat-pointer strings.

* `arbtt_wayland_toplevel.py` - interfaces [arbtt](https://arbtt.nomeata.de/) with Wayland foreign toplevel protocol and idle notifications.
* `fractalize_image.py` - used for making a profile picture for someone once.
* `goose2function.py` - converts goose neck profiles extracted from images of geese into activation functions for machine learning.
* `histretention.py` - dump Firefox `places.sqlite3` into a separate database (Firefox clears out old history internally for performance reasons or something like that) for later search.
* `memeticize.py` - the script I use to process memes from a large directory of heterogenous files.
* `rng_trainer.html` - a very unfinished attempt to implement a paper I found on training high-quality random number generation.
* `smtp2rss.py` - bridge SMTP (inbound emails) to RSS.
* `yearbox.html` - DokuWiki-type yearbox prototype for Minoteaur (I think this actually contains an off-by-one error somewhere; it isn't what's actually in use).
* `arbitrary-politics-graphs` - all you need to run your own election campaign.
* `heavbiome` - some work on biome generation with Perlin noise.
