The British railway system seems to have reduced the volume of stupid inane announcements lately. I'm surprised. I wonder how this was negotiated.
I am, however, running 25 minutes late on a 30-year-old diesel train.

Regretfully informing you that a nasty internal checkpoint of GPT-7 retrocausally hacked into your cellphone microphone that is enabled for advertising reasons, used variations in the 50 Hz electrical grid hum to identify exactly *when* you lost your keys, then correlated aircraft doppler effects to figure out exactly *where* you lost your keys, then used CPU heat telepathy to encourage a fleet of feral cats to push it into a storm drain. You're going to have to buy a new set.

It just ends on this?
Also the "can't" instead of "won't".
I don't like that.

This video examines the amount of location information carried by inaudible background sounds, using the Doppler effect to locate a reference recording within ~100m, and only needing (in some cases) less 1-min of audio. This video raises awareness of these capabilities and closes by discussing preventative measures one could take.

Wow, you don't say.
GAH.
Disallowing "logical" arguments about interpretation of the spec is "interesting".
This is a bit of an Ideological Turing Test failure on the part of whoever writes these.
It should obey the user, or something, here.
Actually, this is at "user"-level in the chain of command? So the newer user message should override it anyway. They seem to have forgotten that.
Experiments
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.
The Limitless Grid screensaver (kind of) implemented in a somewhat laggy pixel shader.
An unfinished attempt to replicate an Apple screensaver.
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".
How bound are you to the habits of the past? Find out with this test.
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.
Your favourite* tic-tac-toe game in 3 dimensions, transplanted onto the main website! 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.
A basic implementation of the WFC procedural generation algorithm.
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.
