Writing this up because I just tripped over it and spent an hour debugging what ended up being an obvious problem. So here’s the situation: You’re running Rails 8 with SQLite as its main database, and you want to replicate / backup that database to Hetzner S3. Bonus points if you’re running Rails on your…

DHH announced Rails 8 adding a lot of support for SQLite at Rails World 2024, which motivated me to give it a shot. I enthusiastically procrastinated this quest. One year later, after visiting Rails World 2025 and realizing this whole SQLite thing was here to stay, I got down to writing some code. I migrated…

At OpenRegulatory, we’re a small team of 4 people, and everyone receives the same salary. There are a lot of tangents I could go down from here – like: Etc., etc. But those are for another day. Today, I’ll be talking about paying everyone the same salary, regardless of location, and regardless of role at…

Thought I’d share this cool snipped as it’s really easy to migrate from “vanilla” Postgres to pgvector in dokku: And that’s all there is.
