Great article. It makes me want to try extralite. I tend to prefer some kind of DSL over raw SQL, but maybe I should give that up. https://noteflakes.com/articles/2026-09-05-beyond-orms

Stripe is the largest Ruby codebase in the world but they share so little about it.
Is it because they don't use Rails so people don't care? Naturally that is what fascinates me most.
It was so cool to read about how Stripe rubyfmt'd their entire 25MMLoC codebase. Glad they're sharing more!

Even though Elm is a drastically less popular language, I find that agents are able to code it much better than Ruby. I think this is due to:
1) the language being simpler
2) the strong compiler providing helpful errors ("backpressure")
