Today is a hard day. I shared this note with the @linear team today: We’ve made the difficult decision to increase our workforce. This is not a cost-cutting exercise or a reflection of anyone’s performance. We’re simply reimagining every role for the agentic AI era. We’re hiring. We’re sorry about that.

Your phone doesn’t use your mic to spy on you.
Reality is much scarier: your phone infects your subconscious and influences what you talk about
By the way I have proof the stock ROM spies on you because I was in the kitchen with it being the only "smart" device in the room and discussing lucid dreams. Then I went back to my computer and saw a bunch of "how to lucid dream" videos on YouTube.
I haven't seen videos relating to the topic in over 4 years so yeah y'all might wanna install Graphene or smth 💀

My favorite way of using cursor is asking it to deconstruct things i want to understand, show it to me step by step rather than one shot generations of things i dont understand. You can build your own interactive explainers.

I've been really happy with `prek`, a pre-commit implementation in Rust (powered by uv :))
A bunch of us on the Astral team started using it organically, and we officially migrated the Ruff and ty repositories to prek this week.

Announcing the Beta release of ty: an extremely fast type checker and language server for Python, written in Rust.
We now use ty exclusively in our own projects and are ready to recommend it to motivated users.
10x, 50x, even 100x faster than existing type checkers and LSPs.
ALT Comparing ty to Pyrefly, Pyright, and mypy on home-assistant.

Extremely excited about this... Vercel is the Vercel for Python
I can't wait for Vercel to add a Killer Rabbit to complement @evilrabbit_
Then shalt thou count to {the number of sides in a triangle}...

We’re bringing Vercel’s DX and self-driving infrastructure to Python, by teaming up with @1st1, @elprans & the Gel team.
I’m so excited to work with these guys. True missionaries that have lived and breathed Python their entire professional lives. I’m confident they’ll make Vercel the best Python cloud.
We’re also sponsoring the Python Software Foundation, core maintainer @SerhiyStorchaka, and are committed to the long-term strength of the open Python ecosystem.

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…

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.
