I had some fun pulling OpenAI's mission statement out of their IRS tax filings from 2016 to 2024, loading them into a git repo with fake commit dates and then taking a look at the diffs simonwillison.net/2026/Feb/13/...

TIL that SQLite has R-trees: www.sqlite.org/rtree.html

This means that I can have a lightweight and portable "mini-PostGIS" database all in one file for super fast range queries that I can take with me to any other computer.

A picture showing an example output of the program on the city of Montréal and the autumn color scheme. You can see a map of the city with all the roads, trains, subways and light rail. At the bottom there the poster is titled MONTRÉAL - QUÉBEC. The latitude and longitude are also written under the title.

A picture showing an example output of the program on the city of Paris and the emerald color scheme. You can see a map of the city with all the roads, trains, subways and light rail. At the bottom there the poster is titled PARIS - FRANCE. The latitude and longitude are also written under the title.

A picture showing an example output of the program on the city of Tokyo and the japanese ink color scheme. You can see a map of the city with all the roads, trains, subways and light rail. At the bottom there the poster is titled TOKYO - JAPAN. The latitude and longitude are also written under the title.

A picture showing an example output of the program on the city of Berlin and the noir color scheme. You can see a map of the city with all the roads, trains, subways and light rail. At the bottom there the poster is titled BERLIN - GERMANY. The latitude and longitude are also written under the title.

A little python program that generates poster for cities! You might have seen stuff like this around lately, but I modified it to put an emphasis on rail infrastructure :3

I find myself returning to it every few weeks, and each time I learn something new.
