I realized I had posted to the packaging thread instead of the PEP thread, so I reposted the same message to the PEP thread.

Sorry, everyone. I think I got a little too excited.

Python 3.15's JIT is now back on track | Python Insider A look at Python's JIT in 3.15a7.

Without Ken Jin’s mentorship, I would not have been able to integrate frozendict into the Python 3.15 JIT infrastructure so smoothly. In CPython’s JIT, frozendict can currently be constant folded when used as a global variable.

Happy to share that PEP 803 has been accepted.

A meaningful step toward Stable ABI for free threading in Python 3.15, with clear importance for C extension support.

I was planning to focus on open source work after finishing my company work today, but I ended up spending time on an unexpected CVE instead.

Something like "open"uv… soon?

If in a few years no humans are writing code anymore, then this might be the last moment we truly get to enjoy it. So enjoy it fully and appreciate the present, so you won’t look back with regret in the future.

I hope that it would be useful to people in practice :)

As of Python 3.15, you can also annotate mmap calls made from pure Python code using the mmap.set_name() method.

2025년에 이어 2026년에도 파이썬 운영위원회 (Python Steering Council ) 멤버로 활동하게 되었습니다. 파이썬 코어팀이 올해 집중해오던 프로젝트들의 모멘텀을 계속 유지하기 위해서 노력하겠습니다.

I would also like to express my sincere appreciation to this year’s members, @gpshead.bsky.social and @emilyemorehouse.bsky.social , who supported me greatly as a new member.

Thank you all for your continued support and trust.

I look forward to continuing to serve the community and helping guide Python’s technical direction in the coming year.
I also look forward to helping strengthen connections between the Python core team and communities in under-represented regions.

I am truly grateful for the opportunity to serve alongside and collaborate with such amazing colleagues on the Python Steering Council: @pumpichank.bsky.social , @pablogsal.com , @savannah.dev , and @yhg1s.bsky.social.

Starting in Python 3.15, anonymous mmap usage will be annotated on Linux (kernel version >= 5.17) when the interpreter is launched with -X dev.
Annotated names are shown in /proc/<pid>/maps, which can help with debugging :)

Very proud that official Korean subtitles is added to “Python: The Documentary” thanks to the amazing effort from
@pycon.kr

It’s the only non-English language with manually created subtitles, not auto-generated.

I am also grateful that I can get positive energy from you everytime.

The passing car meme but with Hugo's github handle

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 :)

Sometimes it is good to try to keep a distance from the topic that I am biased on
