Main Page

This site serves documentation for my various projects, mostly for my own reference, but also as a way to share them. Using a wiki for this purpose is certainly overkill, but it is easy to edit and format, and I am familiar with it. Whenever I do a fairly involved project, there's a decent chance I will write up the things I learned on this site. As it stands, this site is still relatively sparse, because I like working on projects more than writing about them, like most people.

This web server and the content it provides is also a project in and of itself. This is running on server hardware and software that I set up myself, so as such even the content you are reading now is experimental. I guarantee no stability or reliable access, although I will do my best to keep this available online for as long as possible (though as of 2020 I have had a server like this running continuously for over 5 years).

What is the fish?

The green fish is from a game I made when I first learned how to program. Over time, it turned into the logo that I use for my projects.
