Postgres has its own primitives for things that forges currently build custom infrastructure around. A trigger on the refs table firing NOTIFY means any connected client learns about a push the moment it happens, which is how forges normally end up building a custom webhook polling layer. Multi-tenant repo isolation becomes a database concern through row-level security on the objects and refs tables, and logical replication lets you selectively stream repositories across Postgres instances, a kind of partial mirroring that filesystem-based git can’t do. Commit graph traversal for ancestry queries and merge-base computation falls to recursive CTEs, and pg_trgm indexes on blob content give you substring search across all repositories without standing up a separate search index.
I’ll never forget the book. […] The book was a huge compilation of all around interesting stuff. Weird Apple II tricks that were pointless, but endlessly fascinating. Like the fact that there were extra offscreen pixels of lo-res graphics memory that you could write to, that never got displayed. Or how to put “impossible” inverted or flashing characters into your disk directory listing. Or how to modify system error messages. Not very useful, but really fun to know and really, really cool to mess with. My dad was convinced I was going to somehow break the computer with all this hacking, but a simple reboot always fixed everything.

Altman said the government is willing to let OpenAI build its own “safety stack”—that is, a layered system of technical, policy, and human controls that sit between a powerful AI model and real-world use—and that if the model refuses to perform a task, then the government would not force OpenAI to make it do so.
