i mean… everything is gonna turned on its head now anyways with subinterpreters, free-threading/nogil going mainstream, and maybe virtual threads on the horizon 🤪

which will happen first, python shipping nogil, or event rate exceeding what I can handle on one core, lol

The nogil stuff is truly a thing of beauty or of baling wire, depending on one's perspective.

On 2 out of 2 podcasts I've been lately I've been asked what I think about free-threading (aka nogil) & what it means for Python & I gave the same answer:
It's important but we can't know what it means for Python until we have much better abstractions over threading. 1/3

When I was advocating for nogil/free-threading, I always said that it’s important not to judge threads by the APIs we have, but by the APIs we will build once they’re worth the trouble.

Does Bsky care about #Python?
If so, the Steering Council posted their "intent to accept PEP 703", in other words to allow for a version of Python without the GIL.
Sam Gross' heroic effort to prove nogil is feasible will be paying off.

PyO3 0.23.0 is a big release that I have thoroughly reviewed. Support for "free-threaded Python" is part of the title, and I think NoGIL Python is better for Rust interoperability, so there's definitely interest in that crate. It can also be great for queuing data for GPUs, api servers, and bulk data retrieval. For whatever reason (probably post 2to3 PTSD), the Python community doesn't seem to want to jump on the latest Python versions and it often takes a long time for popular libraries to support the latest ones. -or and most importantly, so I recommend patience and baby steps. 2024-12-20 05:42:00

I wouldn't push it with what I do for work (pyspark largely) but for the FIRST robotics stuff it'll be incredibly helpful if we adopt a nogil runtime.
Desktop apps I write in Python would benefit from it but not much.
