I'm writing an article series on Free Threading internals. The second article https://vstinner.github.io/free-threading-deferred-reference-counting.html analyzes immortal objects, deferred reference count, and stack references which reduce reference count contention by optimizing Py_INCREF()/Py_DECREF().

I'm writing an article serie on Free Threading internals. The first article explores the problem of tracking objects lifetime using reference counting in an efficient fashion: https://vstinner.github.io/free-threading-reference-counting.html We will see how the Gilectomy project started with atomic operations and then switched to buffered reference counting, and how the nogil project managed to solve the performance issue using Biased Reference Counting.

I just learned that Dependabot's "cooldown" is not a security boundary, attackers can bypass it quite easily... https://github.com/dependabot/dependabot-core/issues/13078

GitHub Actions cooldown should use release date instead of tag commit date · Issue #13078 · dependabot/dependabot-core

Inspired by @hugovk 's Bluesky Python core devs starter pack, I created one for Mastodon(.social): https://mastodon.social/collections/116540107831540575

A very new feature, and as such quite limited. If I've missed anyone on mastodon.social please let me know! If you're on another instance, I'm afraid I can't add you yet :'-(

Python 3.15 beta 1 is here 🎉! This release comes packed with so many awesome new features, it's a great time to get yourself familiarized with what's landing via the What's New (https://docs.python.org/3.15/whatsnew/3.15.html)

This means CPython main branch has become Python 3.16, which is my first release as release manager. Not to be sappy but this is such an honour.

We still have 3.15.0 final to look forward to, but if you're antsy, the tentative release schedule for 3.16 is already live

I’ve seen the „my English is poor and AI helps me gather my thoughts” excuse for AI spam so many times now on various forums. While it is a reasonable reason to use AI, the frequency does make me wonder if it’s just a way bots were trained to respond… or maybe just apophenia.
