just saw some python asyncio for the first time in years and was reminded that the most basic "hello world" is still worse than the evilest tokio code I've ever seen

Another day, another part of my codebase made infinitely simpler by ripping out asyncio.

pytest-asyncio just hit 1.0, congrats to the team 🎉
That's a very long fucking way from when I started working with asyncio in 2017 and it was barely usable 🥲

the Nintendo 3DS is a very fun device to write homebrew for, but one thing about it can be annoying: its multitasking is non-preemptive!

> is asyncio a convenience wrapper for threading
it is not. asyncio is not threads in the tradition sense, though they are both concurrency paradigms.
three main types of concurrency are OS processes, threads (usually via OS apis), and coroutines. asyncio is coroutines.

The good thing about Python is that you can monkey patch. The bad thing about Python is that sometimes you have to. That's the only way I managed to automatically run some async code on startup in an async shell.
PYTHONSTARTUP=http://shellstartup.py uv run python -m asyncio
PYTHONSTARTUP=http://shellstartup.py uv run python -m asyncio

To fulfill the expectations of all Python people who followed me, I'll start sharing some of the Python stuff I'm dealing with now. E.g. right now I'm working on adding asyncio call stack introspection support both from within the process and from outside of it. ✨
