This is, of course, all part of my evil plan to drive site activity through systematically generating (meta)political outrage.

Powerful search tools as externalized cognition, and how mine work.

Learn about how works internally! Spoiler warning if you wanted to reverse-engineer it yourself.

A common criticism of school is that it focuses overmuch on rote memorization. While I don't endorse school, I think this argument is wrong.

RSS/Atom are protocols for Internet-based newsletter/feed services. They're surprisingly well-supported and you should consider using them.

Is solving Sudoku and similar puzzles by hand really useful in building computer science ability? We don't think so.

We are not responsible if these tips cause your ship to implode/explode. Contains spoilers in vast quantities.

My (probably unpopular in general but... actually likely fairly popular amongst this site's intended audience) opinions on smartphones today.


Short-form observations.

Did you know? Man created computer hardware, but God gave us computer software as punishment for our hubris.

Does anything still work for getting RSS feeds off Twitter? I used to run a Nitter instance, but that has broken even with every ugly hack I can throw at it.

It's important to optimise your expenses so you can focus on what really matters in life (high-performance computer hardware).

It looks like this, since apparently that did not autoembed.

If you enjoyed Threat Update ( you might like my similar service: just go to to see the current threat level.

I should really have a better way to keep CSS consistent across services than manually copypasting parts of it sometimes.


Various web projects I have put together over many years. Made with at least four different JS frameworks. Some of them are bad.

A game about... apioforms... by Heavpoot.
Collect Arbitrary Points and achievements by doing things on this website! See how many you have! Do nothing with them because you can't! This is the final form of gamification.
Automatic score keeper, designed for handling Monopoly money.
Colorizes the Alphabet, using highly advanced colorizational algorithms.
Survive as long as possible against emus and other wildlife. Contributed by Aidan.
Fly an ominous flying square around above some ground! Includes special relativity!
A somewhat unperformant generator for pleasant watercolor-y "fractalart" images. Ported from a Haskell implementation by "TomSmeets".
My fork of GUIHacker. Possibly the only version actually on the web right now since the original website is down.
Obligatory (John Conway's) Game of Life implementation.
It is pitch black (if you ignore all of the lighting). You are likely to be eaten by Heavpoot's terrible writing skills, and/or lacerated/shot/[REDACTED]. Vaguely inspired by the SCP Foundation.
Generates ideas. Terribly. Don't do them. These are not good ideas.
The exciting multiplayer game of incrementing and decrementing! No cheating.
Outdoing all other websites with INFINITE PAGES!
Tells you how late Joe's homework is.
Lorem Ipsum (latin-like placeholder text), eternally. Somehow people have left comments at the bottom anyway.
Instead of wasting time thinking of the best political opinion to hold, simply pick them pseudorandomly per day with this tool.
A Reverse Polish Notation (check wikipedia) calculator, version 2. Buggy and kind of unreliable. This updated version implements advanced features such as subtraction.
Reverse Polish Notation calculator, version 3 - with inbuilt docs, arbitrary-size rational numbers, utterly broken float/rational conversion and quite possibly Turing-completeness.
Reverse Polish Notation calculator, version 4 - increasingly esoteric and incomprehensible. Contributed by Aidan.
Apply custom CSS to most pages on here.
Your favourite* tic-tac-toe game in 3 dimensions, transplanted onto the main website via a slightly horrifically manual process! Technically this game is solved and always leads to player 1 winning with optimal play, but the AI is not good enough to do that without more compute!
More dimensions. More confusion. Somewhat worse performance. 4D Tic-Tac-Toe.
Type websocket URLs in the top bar and hit enter; type messages in the bottom bar, and also hit enter. Probably useful for some weirdly designed websocket services.
Dice-rolling webapp. Not very useful pending me writing a good parser.
Unholy horrors moved from the depths of my projects directory to your browser. Theoretically, this is a calculator. Good luck using it.

Terry Gilliam’s Air Canada

Being who I am, I tend to portray my futures in the spirit of Orwell’s Nineteen Eighty Four or Brunner’s The Sheep Look Up. Sometimes, though, reality turns out more like Gilliam’s Brazil: just as grim, but hysterically so. Take my short story “Collateral…
