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.

This weekend, for the first time, I gave a talk that was simultaneously in person and remotely shared :tada:

At the same time as we were having our monthly Python Floripa meetup in person, my talk was broadcast to the 1st NOSS - "Nosso Open Source Summit" (Our Open Source Summit, in Brazilian Portuguese).

Boa noite para quem não gastou duas semanas tentando fazer uma dieta Atkins muitíssimo mal feita e teve que parar porque vômitos, fraqueza, dor de barriga e falta de energia foram um pouco piores que o esperado!

Morri mas passo bem.

Perdi uns 2kg (o peso baixou 5kg, mas uns 3kg eram de água), certeza que foi 100% de massa magra.

Agora vou na nutricionista e na endócrino, que não tenho mais idade nem saúde pra essas aventuras.

E você, que cagada obviamente cagada fez nesses últimos tempos?
