The team from Quansight-Labs
is writing the migration guide for the free-threading CPython while they are working on a bunch of scientific libraries (e.g numpy)
IMO, it is worth taking a look at.

I've been using a new Linux laptop since last week, and I've noticed a problem with Linux's battery management. Unfortunately PPD and TLP do not satisfy my expectations. And I found a cool management system that is written in Python :)

With 13 patches, the list is now maybe(!!) compatible with PEP 703 implementation.
I annotated "maybe" because we can not be sure until the GIL is truly disabled.

There is a concept of object pool for object allocation in CPython, aka free list.
The free list currently exists per interpreter with default build CPython.
For PEP 703, it should exist per thread to avoid race conditions and lock competition.
Now CPython supports both per-thread and per-interpreter freelist in a seamless way without touching the runtime implementation.
Discussing design with Sam Gross and Eric Snow was quite an exciting experience.

Hi, I get an invitation to fosstodon.org from @erlendaasland
I am going to publish something about CPython and compiler things :)

Not sure how helpful information will be included!
