Now that @europython.eu talks are live, I want to plug some of the very cool things™ my friends presented: - @diegor.it's talk on the JIT: www.youtube.com/watch?v=5si4... - @maureira.dev's talk on what comes after Rust in the Python ecosystem: www.youtube.com/watch?v=yJPX... (🧵 Cont'd below!)

Wooo, unanimous acceptance of 810! Python is getting lazy imports! So excited about this! discuss.python.org/t/pep-810-ex...

Great write up! Thanks!

Check out this post by @diegor.it about the latest CPython sprint! We send a special thanks to Arm for hosting the event and investing in the future of #Python 💛🐍💙 pyfound.blogspot.com/2025/10/cpyt...

14 years at @developer.arm.com, reflecting on wins, doubts, pivots, and the role of Python 🐍 has played. I just shared a longer version on LinkedIn: how I went from Italy🇮🇹 → UK 🇬🇧, leaned into Python, built community & kept pushing. Read it here: www.linkedin.com/feed/update/...

Thank you, @developer.arm.com, for investing in the future of #Python and the PSF by hosting this year’s CPython sprint– we appreciate your support!

🐍 CPython Core Dev Sprint 2025 wrap: ~50 core devs (yes, Guido too) and invited guests hacking in Cambridge. JIT, free-threading, C-API, endless side discussions. It's safe to say the best ideas start over coffee and a whiteboard with @python.org: community.arm.com/arm-communit...

Last month the CPython Core Dev Sprint 2025 took place at Arm (@developer.arm.com) Cambridge. 🔧 I’ve just published a full write-up on what happened, what went into organising it, and what it means for Arm & the Python community. 👉 Read it here: community.arm.com/arm-communit...

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.

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.

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

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!

Is there an easy way to format text here in Bluesky? I found this thriendly.com/bluesky-form... but I would rather doing directly on Bluesky. *this* __doesn't__ _seem_ {to work}
