I'm really looking forward to speaking at @RustNationUK 2025! I have a ton of crazy Rust stuff we've done in PyO3 which I can't wait to get your take on 😁

Big Day for Pydantic: Pydantic Logfire is leaving beta and we're announcing our Series A from @sequoia & @PartechPartners pydantic.dev/articles/logfi…
Today, we're shipping a series of features that move uv beyond a pip alternative, and into an end-to-end solution for managing Python projects, command-line tools, single-file scripts, and even Python itself. A single, unified tool. Like Cargo, for Python. It's very fast.
"When you're working with superconductors, copper is an insulator" #rustlang tools like cargo-semver-checks, release-plz, PyO3, and maturin are helping make fusion power a reality at @CFS_energy!
We're having a lot of fun scaling up greenfield Rust services to power the backend of @pydantic Logfire! To do that faster we'd love some additional firepower; interested in Rust & distributed database engineering? Read below 👇

In my quest to produce a shorter video, I’ve produced my longest so far: tox vs Nox: What are they for & How do you choose?: youtube.com/watch?v=ImBvrD… In which I introduce those two indispensable tools and reflect my own usage of BOTH. Enjoy!
Had a great time at the @pycon sprints yesterday leading a group working on PyO3! I'll be back in room 321 again today before I head back to the UK tonight. Come say hi!
tfw you put submit a @pycon lightning talk proposal with just a title but no actual content in mind
Had a great experience giving my first talk at PyCon US just now! Thanks to everyone who came to hear me enthuse about Rust and Python! 😁
PyO3 0.21.2 just released! A few compile-time fixups, nothing particular to highlight. github.com/PyO3/pyo3/rele… Also, for anyone wondering where the PyO3 development streams have gone - family responsibilities have filled my April slots, I'm hoping in May we can resume!
We're very happy to announce that @nvidia and Polars will work together to bring GPU acceleration to Polars DataFrames! 🚀💯 pola.rs/posts/polars-o…
It's time to share my #rustnationuk24 review blog post: janus.rs/en/2024/04/rus…
Pydantic V2.7 is going to be biggest release since V2. Here's some of the best bits: 🚀 roughly 50% performance improvements due to the PyO3 work from @davidhewittdev, SIMD JSON parsing and some associated cleanup 🫸 Partial JSON parsing support, specifically to support…

It's finally time for a "decrusting tokio" stream! We'll talk about blocking, cancellation, spawning, mechanisms for synchronization, and some relevant under-the-hood things. Will happen 12:00pm UTC on Friday (everytimezone.com/?t=660f3f00,2d0) on YouTube: youtube.com/live/YlTyZvpay…
New in the PyO3 Discord: a #hiring channel. Are you looking for developers who can work on mixed Rust/Python codebases? Are you a developer who wants to work on one? Join the Discord server at discord.gg/33kcChzH7f
This is the first time I've publicly talked about the cargo-semver-checks origin story! How does "I hate debugging" evolve into a new tool for the #rustlang ecosystem? Check it out here 👇

That feeling when the bug report immediately following a patch release tells you the patch in question didn't quite address all the edge cases... If only I'd caught it in the first review! github.com/PyO3/pyo3/pull…
PyO3 0.21 was released last week, unlocking the performance opportunities of the new API to all Rust/Python projects based on it. I'm looking forward to hearing how adoption goes! github.com/PyO3/pyo3/rele… Thank you to all contributors who helped implement the new API. There was…
Thanks everyone who came to my PyO3 tutorial earlier at @RustNationUK! For those who didn't make it - I keep being asked to do a tutorial stream on PyO3 - now I have the content I have no excuse! (Well, just need to find the time. Stay tuned 😂)
