Agreed, benchmarking, I only see a slight speedup on MacOS - https://github.com/leontrolski/postgresql-testing#:~:text=ra...

Being to lazy to think or test it - does the above reset SEQUENCEs?

I concur with this approach. TRANSACTION-y tests (the default in Django) often don't quite line up with reality and make it hard to eg. drop in a breakpoint and run a server against the test's db state.
I've experimented (see below) with TEMPLATE dbs and such in Python (with inspiration from this library). IMHO the "around 100ms" mark is pretty slow for a big test suite. Interestingly, pg_restore is only twice as slow as TEMPLATEs.

I'd be interested about how all this compares to snapshotting the postrgres dir with ZFS and restoring to that, but don't have a Linux box to hand.

Neat.

What would be the equivalent to this in Haskell (with or without lens):
cat = Cat(age=3)
l = [1, [2, cat], 4]
alt l[1][1].age.=9
[1, [2, Cat(age=9)], 4]Comment · 6 months ago
This is surprising to me:
l[1][1].age:9
# (1,(2,{"age":9}),4)
{"age":9}
l_inner = l[1][1]
l_inner.age:9Comment · 7 months ago
Yes, AI or no AI, tell me about something actually interesting that you're working on.
Currently it feels a bit like everyone is talking about what new editor they're using. I don't care about that type of developer tooling very much. AI isn't coming up with some exciting new database, type system, etc etc.
"Look at how I'm able to web dev x% faster" because of LLMs is boring.
