Calvin #1: Free-threaded Python: past, present, and future

• The GIL has prevented true multi-threaded parallelism in CPython since the beginning — multiple past attempts to remove it failed on performance grounds
• Sam Gross at Meta finally solved it; his work became PEP 703 and ships as free-threaded CPython today
• Python 3.13 was experimental with 20–40% single-threaded slowdown; 3.14 brought that to 0–10%
• Python 3.15 (October 2026) delivers a unified ABI — one extension binary works on both GIL and free-threaded builds
• Already >50% of the top PyPI binary wheels support free threading
• Wouters predicts free-threaded becomes the default between 3.16–3.20 (2027–2031), with the GIL eventually disappearing next decade

Michael #2: django-admin-site-search

• via Adam Parkin
• A global/site search modal for the Django admin, by Ahmed Aljawahiry. Hit cmd+k anywhere in the admin and you get a command-palette-style search window, kind of like the one in VS Code.
• It doesn't just search one model's list page. It searches your entire site in one box:
  • App labels
  • Model labels and field attribu
