Huge thanks to @fastly.com for 10+ years of keeping #PyPI up and running! PyPI serves 800K+ users at ~100K requests/sec. With a small team behind the service, that kind of scale is only possible because of infrastructure partners who invest in the sustainability of the #Python ecosystem.

Exciting, see you there!

Big news! 🎉 I am keynoting at @pyconit.bsky.social

PyCon Italia was the first Python conference I ever attended back in 2010. It is where my PyCon journey began. Being back now as a keynote speaker feels special, like closing a circle.

See you all in Bologna! 🇮🇹

State of WASI support for CPython: March 2026 It's been a while since I posted about WASI support in CPython! 😅 Up until now, most of the work I have been doing around WASI has been making its maintenance easier for me and other core developers. ...

Wrote a blog post to give a status update on WASI support for CPython as PEP 816 got accepted!

Still waiting for an Yle investigation to reveal that the media and government have exploited Finland's image as the "happiest country in the world" to sell an inaccurate or downright misleading image of life in the country.

Introducing the PSF Community Partner Program The Python Software Foundation (PSF) is excited to announce the introduction of the PSF Community Partner Program. This new program is designed as an “in-kind” way for us to support Python events and initiatives with non-financial assistance through the use of the PSF logo and name, as well as promotional support via sharing qualified posts on PSF official social media accounts. The PSF looks forward to supporting Python community events and initiatives through this new program!The introduction of the PSF Community Partner Program grew out of our desire to find alternative ways to support the community during the pause of our Grants Program (read more about the resulting process below). Even so, we intend to continue offering this in-kind support program after the Grants Program reopens. Our big picture hope is that, over the long term, some community events and initiatives will continue to partner with the PSF while being financially dependent on sponsors and individual donors alone. The PSF is also working on the future of our Grants Program, including when and how we can reopen it in a way that ensures the program’s long-term sustainability while balancing the needs of the Python community. In light of the truly staggering outpouring of support from our community during the 2025 year-end fundraiser, we are now in a stronger position to reopen the Grants Program and are eager to give back in a thoughtful and sustainable way. More updates to come!As with the rollout of any new program, we anticipate small adjustments will need to be made for processes to flow smoothly and to ensure the program serves the Python community well. The PSF welcomes your comments, feedback, and suggestions regarding the new Community Partner Program on the corresponding Discuss thread. We also invite you to join our upcoming PSF Board or Grants Program Office Hour sessions to talk with the PSF Board and Staff synchronously. If you wish to send your feedback privately, please email grants@python.org. 

Introducing the PSF Community Partner Program! The PSF is very excited to announce this new in-kind offering that expands how we support Python community events and initiatives around the world, now and alongside future community support programs 💝🐍

Revealed: How Substack makes money from hosting Nazi newsletters Exclusive: Site takes a cut of subscriptions to content that promotes far-right ideology, white supremacy and antisemitism

I’m late in sharing it, but here is another piece about Substack making money off Nazis.

Those writers — especially those who say they are fighting tyranny and injustice — on the platform know better by now.

No excuses.

With some finagling, I managed to build @fastapi.tiangolo.com against Python 3.15 to run the new FastAPI pyperformance benchmark, with and without the JIT.

3.13: 142ms → 141ms w/ JIT (~0.7% faster)
3.14: 147ms → 149ms w/ JIT (~1.4% slower)
3.15a5+ (main): 145ms → 134ms w/ JIT (8% faster!!!)

Speeding up Pillow's open and save

Using the new Tachyon profiler coming to Python 3.15 I profiled a one-liner to find a bottleneck, and sped up some 26-year-old code in @pillow.fosstodon.org.ap.brid.gy!

I run a server farm in my closet (and you can too!) One woman's quest to answer the question: does JIT go brrr?

Wrote up how I ended up with four machines in my closet running nightly JIT benchmarks.

The answer to "does JIT go brrr?" is roughly "yes, YMMV... about 2-15% faster depending on your hardware" 🤠

Output of running "pypistats overall pytest-socket --monthly --mirrors without". It's a table with category, date, percent and downloads headers. The rows are sorted by downloads, highest first.

Output of running the same command but with "--sort date". The rows are now sorted by date, earliest first.

By popular demand (@miketheman.com), pypistats now has a `--sort` option so you can sort by other columns such as date, rather than the default downloads.
