I will continue streaming with Petr Viktorin tomorrow 3rd July, 8:30 AM UTC. We are making progress towards our prototype of CPython which natively supports UTF-8 as the primary datatype for Python strings. Please join us then! youtube.com/live/Aggf7H7...

I'm looking forward to returning to streaming at 9:30 AM UTC tomorrow 27th March. Please join myself and Petr Victorin as we begin a project to work on CPython's `str` implementation - targeting optimizations when exchanging data with Rust UTF-8 strings. www.youtube.com/live/fXeqeFX...

Absolutely loving using github.com/rvben/rumdl to lint markdown, just like `ruff`, it's crazy fast! I just signed up as rvben's first GitHub sponsor, calling on everyone to join me in showing this project some support!

I currently have availability for Rust coaching, adoption, or development; from a single call to ongoing 3 days/week. I can help your team get things done, adopt Rust and use it more effectively, or to accurately evaluate Rust as a new technology.

Going live in 10 minutes! Come see us play with Rust, AI and AI-assisted debugging!

I will be going live in 5 hours to play with OpenAI Codex CLI and show the power of combining it with Pydantic Logfire's Rust SDK and MCP server to debug Rust apps. Should be a relatively gentle introduction to AI-assisted development, please come along check it out! pydantic.dev/articles/ope...

I'm *so* excited to share that I am now officially a CPython Core Developer! 🥳 I wrote my first Python in 2012, and immediately fell in love with the language. I'm honored that I am a part of, and can give back to, such an amazing, welcoming community! discuss.python.org/t/vote-to-pr...

As her mentor, I am very happy to propose promoting Emma Smith (@emmatyping on DPO and GitHub) to core developer. Emma has been a long time contributor to Python in many areas over the years, from myp...

I completely agree with this great blog post by @nikomatsakis.com betting that Rust, Python and Typescript will be stables of the AI coding era 👍 These languages combined have the package ecosystems and domain coverage to meet most programming needs. smallcultfollowing.com/babysteps/bl...

Build a tool with Rust, then integrate it into Python with the amazing PyO3 🦀 😍 📈

pyo3 is great. sick of Rust compile times? Just build your Rust crate into a Python module, then use it with all your other Python

The uv build backend is now stable, and considered ready for production use. An alternative to setuptools, hatchling, etc. for pure Python projects, with a focus on good defaults, user-friendly error messages, and performance. When used with uv, it's 10-35x faster.

A bit of a long shot: the regular audio editor for the "What's New" Rustacean Station episodes is now busy with other life stuff. The last episode I edited myself, but it took ages! Anyone know an editor (ideally familiar with Rust, but not a requirement) who'd take on a regular (paid) editing gig?

Thanks to everybody who came to my talk at #PyConUS yesterday! As promised, here are the slides: pycon-us-2025-davidhewitt.vercel.app

#PyconUS attendees. Have time? We REALLY need more volunteers tomorrow, Sat 🥺. Green room volunteers, session runners, swag distribution, registration,information desk. Login to us.pycon.org/ on your dashboard, click on volunteer>volunteering. Pick the time you're free!

I like to think that when Charli xcx sang “Unlock It (Lock It)”, she was referencing thread safety with mutexes.

Our social run group this morning at #PyConUS Ed, Hynek, David Hewitt and David Lord. Running again 7:30 Saturday anyone welcome!

🎂 Rust turns 10 today! 🎂 To mark the anniversary of Rust 1.0, we’re excited to share a reflection by Graydon Hoare, the initial author of Rust. It’s a story of infrastructure, community, and extraordinary collaboration. Read Graydon's guest blog here: rustfoundation.org/media/10-yea...

I’m at PyCon US today! 😁

Please come join us today at #PyConUS - I develop and monitor Pydantic Logfire using Pydantic Logfire, and I believe others can get so much value from our platform too!
