After hosting the CPython Core Dev Sprint at Arm, I went to @pyconuk.org in Manchester. I even brought my kids so they could experience a Python conference. 🐍💙 I stepped in last-minute to give my talk on the CPython JIT. 😎 Recordings here 👉 youtu.be/5-AA7-fHYYM?...

The CPython Core Dev Sprint 2025 in Cambridge is a wrap, the biggest and best yet! 🎉🐍 50+ core devs, Python 3.14rc2 released, Arm talks on ISA/compilers, and a true Cambridge experience! I’ve shared the full story (with photos) on LinkedIn 👉 www.linkedin.com/feed/update/...

🐍 The Python ecosystem on Arm is thriving! From native GitHub runners to JIT optimizations and PyTorch on Windows, the platform is more mature than ever. And there’s more coming, check out our 2025 update: 🔗 community.arm.com/arm-communit... #Python #CPython #Arm #OpenSource #WoA

We are expanding the CPython team in the Runtimes organisation at Arm, hiring Senior Software Engineers in Cambridge/Manchester. 🇬🇧 Love diving into CPython internals or improve its performance?🐍 Apply here:👇 careers.arm.com/job/cambridg...

I just got back from @europython.eu 2025! I spoke about the CPython JIT, mentored a new speaker, introduced the keynote, and connected with amazing people. Now even more proud to be part of this community 🐍💛 📖 Full recap on LinkedIn: www.linkedin.com/feed/update/...

I gave a talk at @europython.eu about “Exploring the CPython JIT” where I go to a journey in the execution pipeline, from the Python source code to native machine code. Feel free to reach me out if you have any question.

Diego Russo, Python Core Developer, is speaking about "Exploring the CPython JIT" in the main hall of EuroPython 2025 🐍 #europython #europython2025 #python #cpython #jit #compilers https://ep2025.europython.eu/session/exploring-the-cpython-jit CC @europython

Just landed in Prague for @europython.eu :)

⚠️ This post is in Italian! 🇮🇹 (just this once 😉) Parlo di interpreter, JIT, PEP 11 e community in Intervista Pythonista 🎙️ 🎧 Spotify: open.spotify.com/episode/75Fk... 🍎 Apple: podcasts.apple.com/gb/podcast/i... #Python #CPython #Podcast

I hope to see you all in Prague next week!

What are you looking forward to at EuroPython this year?

🚀 My #MSBuild2025 session is live! Learn how CPython & PyTorch now build and run natively on Windows on Arm using GitHub-hosted runners, no cross-compilation needed! Watch here 👉 build.microsoft.com/en-US/sessio... #PyTorch #CPython #GitHubActions #Arm64

Just attended my first Python Language Summit! 🐍 A day full of fascinating discussions, ideas, and brilliant people. Grateful to be part of this amazing community.💙 #PyConUS

There were layoffs at MS yesterday and 3 #Python core devs from the Faster CPython team were caught in them. If you know of any jobs, please send them their way: Eric Snow: www.linkedin.com/in/ericsnowc... Irit Katriel: www.linkedin.com/in/irit-katr... Mark Shannon: www.linkedin.com/in/mark-shan...

I’m officially a CPython Core Developer! 🐍 I’ve been using Python since 2006 — contributing back was a dream, and now it’s real. Huge thanks to everyone who supported me, and to Arm for backing me from day one. It’s not the destination — it’s the journey. 💙 🔗 discuss.python.org/t/vote-to-pr...

The spec for pylock.toml is up! packaging.python.org/en/latest/sp...

🔥 PyTorch native builds are now available for Windows on Arm! ✅ No x64 emulation 🚀 Faster performance 📦 Works on Surface Pro X, Dev Kits & GitHub Actions Dev workflows on Arm64 just got way better. 🔗 blogs.windows.com/windowsdevel... @microsoft.com #PyTorch #WindowsOnArm #AI #ML #Arm64

Sending a big thank you to Arm for providing ARM GitHub Action runners to CPython ahead of the public preview launch today! github.blog/changelog/20... #python #cpython

BREAKING! Guido van Rossum, the legendary creator of #Python, has officially reinstated himself as Benevolent Dictator for Life (BDFL). Feat. Guido van Rossum, @pumpichank.bsky.social, @snarky.ca and @mariatta.ca‬ Stay tuned for the documentary coming this summer! www.youtube.com/watch?v=wgxB...

I'm thrilled to announce that my proposal “Exploring the CPython JIT” has been accepted at @europython.eu 🐍🚀 I look forward to sharing an in-depth look into the technical details of JIT compilation for CPython. See you at #EuroPython2025

🚀 EuroPython 2025 tickets are now on sale! 🚀 Join us in Prague for a week of learning, networking, and fun. 170+ talks and hands-on tutorials & workshops, open spaces, sprints, beginner unconference day, social events, and more. Grab your ticket at europython.eu/tickets 🐍🎟️

I'm wondering who the first keynote speaker is... @savannah.dev so you anything about that? :)

Recently I've received an M4 Max for work. To me this the best machine out there for development* The battery lasts forever, it is amazingly fast and you can run natively your code on Arm on all major OSes (macOS, Linux and Windows). (* OK OK, it depends what you do)

From @1st1.dev “And then I thought, well, there are these weird things that they have absolutely no use in the real world whatsoever: functional programming languages” 😂 From core.py: Episode 19: Async hacks, unicorns and velociraptors, 8 Mar 2025 podcasts.apple.com/gb/podcast/c...

I've been reviewing @europython.eu talks submissions! Only if people would have had some more effort to put in the abstract/outline. Lots of cool talks though! I really look forward to it!

That's the news I've been waiting for months! github.blog/changelog/20... If you have an OSS project, Arm-native developers can now build, test, and deploy entirely within the arm64 architecture without the need for virtualisation on your Actions runs, all for free! Build the future on Arm!

This is an impressive achievement!

I’m really excited to announce that the CPython project (www.python.org) has hit a huge milestone by integrating the Arm runners on GitHub! This isn’t just a tech update; it’s a sign of the awesome collaboration in the Python community. 😎

Got an email, "Thank you for coverage․py." I immediately thought, "they're going to want something, or complain about something." Nope! It was all positive. Ended with "Thanks again for this awesome Python contribution!" If you like what someone has done, tell them!

In the past days I worked on this PR: github.com/python/cpyth... In theory it should be an "easy" job, it's just a bunch of yaml files but it took me some time to figure out how it works, to read the documentation and then to create the PR. Here, the issue with such changes:

In my discovery tab I see a lots of post with "space" images. I mean, I like them but sometimes it too much. How can I decrease the frequency of these images?

Who's next? :)

Dear #bsky new user, please spend some effort in filling out the description of your profile. If you start following people and you have no description, no posts, a very random username and the default avatar image, people won't likely follow you.

Recently I gave a try at uv. I couldn't believe how fast it is! ⚡

Did you know you can save 30% on PyCharm now and help support the #Python Software Foundation at the same time? discuss.python.org/t/help-power...

After a week of nightmares 😱 and long stares at the abyss that of gcc, llvm, libunwind, elfutils, several JITs and much more me and Brandt have a proposal to allow unwinders to work with CPython’s new JIT which will avoid breaking all the tools that rely on them ✨ github.com/python/cpyth...
