Other versions of this website

This page also exists on the tildeverse, a bunch of *nix computers that let people sign up for shell accounts. A typical shell account features clients for IRC and email, common terminal/commandline utilities, and (most importantly) web hosting. Read about the tildeverse’s origins, read the FAQ, pick a tilde and get started. My Tildeverse pages will serve as a “rough draft”.

Location (Rohan, meatspace)

Currently living at home in Cupertino, CA

Would normally be in Portland, OR during the school year, but COVID-19 happened.

Location (Seirdy, online)

My handle is “Seirdy” on all the platforms I use.

My Matrix account used to be but I’ve since migrated to my own Conduit server. Conduit doesn’t (yet) support v9 rooms, so I keep my old account around just to join those.

If you find a “Seirdy” somewhere else and don’t know whether or not it’s me, please contact me and ask instead of assuming that it must be me.

My preferred forge for personal projects is Sourcehut, but my repositories have remotes for GitHub, GitLab, and Codeberg too.

Selected projects


Analyze WeeChat logs to quantify, graph, forecast, and perform anomaly-detection on IRC channel activity. Written in Python; uses Pandas.


Generate passwords and analyze password strength given physical limits to computing. Based on a weblog/gemlog entry: Becoming physically immune to brute-force attacks. Written in Go.

Interests, preferences, et cetera

I ought to come up with more interests than these, but that sounds hard.

Free software

The word “free” in “free software” refers to freedom, not price. I recommend looking it up if you aren’t familiar. That being said, I think that simply meeting the definition of free software isn’t enough: it’s one of multiple requirements for software to avoid the possibility of user domestication.

I lean towards simplicity; I usually prefer CLIs that follow the UNIX philosophy over TUIs, and TUIs over GUIs. If a piece of software is complex enough to require a funding round, I would rather avoid it. There are exceptions, of course: I use a Linux distro with Systemd (Fedora), after all.

Some software I use: Fedora, Alpine Linux, SwayWM, mpv, mpd, Minetest, Neovim, tmux, newsboat, WeeChat, Foot, and zsh.

More information is available in my dotfiles repo; check its README.


I watch anime. Some of my favorites, in no particular order:

  • Code Geass
  • Mawaru Penguindrum
  • No Game No Life: Zero
  • Darling in the Franxx
  • Black Lagoon
  • Serial Experiments Lain
  • Saga of Tanya the Evil
  • Monogatari
  • Attack on Titan


I’ve put together a periodically-updated list of tracks that I’ve rated 8/10 or higher in my mpd stickers database, auto-generated by some of my mpd-scripts. I’m a fan of glitch, trailer music, and symphonic and power metal; I’ve also recently been getting into Japanese rock thanks to a few anime openings. Some of my favorite artists are The Glitch Mob, Pretty Lights, Beats Antique, Hammerfall, Badflower, Celldweller/Scandroid, Helloween, Two Steps from Hell, Nightwish, Mili, and MYTH & ROID.
