Python companies: $1.5m is nothing. Pony up.
TLDR; The PSF has made the decision to put our community and our shared diversity, equity, and inclusion values ahead of seeking $1.5M in new revenue. Please read and share. pyfound.blogspot.com/2025/10… 🧵 pyfound.blogspot.com/2025/10…

Prototyping with AI is easy. Shipping with it is… messy. I sit down with @1st1 to argue both sides: vibe coding vs real engineering, context limits, bad tests, and the open-source trust challenges.

european minds can't comprehend what truly slow is
If it's so straight, why is it so slow?

Context is the new RAM
telling that there's no rails
The new steam age. This is actually becoming true in many cases. It's possible to do so much more on your own now.

Who's hungry? There's pi 🥧 FastAPI 0.118.3 has official support for Python 3.14 🎉 Big thanks to @OxyKodit for a long debugging and preparation process! 🙌 And shoutout to @1st1 and @fantix from @geldata for the new httptools with support for 3.14 🙇

So excited for Python to get more love and options. Our sites & UIs live on Vercel, now we can host some of the Python code there too. Thanks to @charliermarsh for *gently* nudging Python packaging with uv. :) I just recently switched to using uv myself and I'm building something to make it even better. More details soon 👨‍🍳
🐍 The Python Cloud Excited to be working with @astral_sh on integrating their incredible, high-performance Python tooling.

wait until there's a feedback loop between behavioral profiling and ai slop machine. heavy drugs will look like toys.
I wish asyncio had a `group()` function, see the snippet. Basically a version of `gather()` that uses a TaskGroup under the hood. Clear cancellation strategy when things go wrong and exception groups. Example: `r1, r2 = await group(thing1(), thing2())` Should I?
