¡Es un honor para mí dar una keynote en PyCon España! Muchas gracias a la organización por la invitación. Tengo muchas ganas de compartir este espacio con la comunidad Python en España y de vernos allí. Ahora sólo me falta aprender catalán antes de subir al escenario😅

No veo la hora de compartir lo que estoy preparando! :)

🎤 ¡Keynote en #PyConES2026! 🐍✨ @diegor.it presenta "Ultreia: ¿Cuándo una idea pasa a ser Python?". Un viaje por el JIT experimental de CPython, PEPs, free-threading y gobernanza. 🧠🚀 #PyConES2026 #PyConES #PythonEspaña #CPython

It's really an honour serving the Python community through EuroPython!

💛 Four days, hundreds of people, countless memories. PyCon Italia 2026 may be over, but we can still relive it all through our official photos. ▶️ Watch the video. 📸 Flickr albums are in the comments👇 #PyConIT #PyConItalia #PyConIt26 #PythonCommunity

I look forward to presenting with Gleb (khmyznikov.com) from @microsoft.com about the progress made on the Python ecosystem on Windows on Arm @developer.arm.com

The Steering Council has asked for a proper PEP for the CPython JIT. I’m happy to help coordinate that work. If you want to contribute as author, reviewer, or with any related input, please get in touch. discuss.python.org/t/an-announc...

I really look forward to delivering these two talks at EuroPython! Don’t miss them!

In 2010, I attended my first Python conference: PyCon Italia Quattro. Last week, I returned to @pyconit.bsky.social to give my first keynote. A real full-circle moment. I shared some reflections (and the slides) on LinkedIn: www.linkedin.com/feed/update/...

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/...

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?
