Going to report a bug literally any Python project on GitHub to find @hugovk.dev already got there before you, reported it and fixed it. Every time.

Most of my recent OSS contributions are connected to projects at my company, even if the contributions are small or simple. So I still believe the best way to start contributing to open source is by working on, or aligning with, your day-to-day projects :)

During the CPython core sprint, I was glad to close the issue by fixing it so that the JIT can now pass unittests without any optimizations(no-opt). This will be the basic step to make the JIT compatible with free-threading.

Yesterday I joined @bernsteinbear.com for live debugging for my stuck PR on his JIT project, and it was an outstanding experience. Learning directly from people like him is priceless, and I truly hope more mentors like this can have greater impact in the community.

I met Max Bernstein today, an expert in Python (Cinder, Skybison) and Ruby JIT (ZJIT). We had a fascinating conversation about JIT compilation in both Ruby and Python while walking around a historic palace in Korea.

We'll drop the "experimental" label already in 3.14 beta 3, due on Tuesday!
