Now

A now page : what has my attention this month. Last updated 2026-07-10.

Building Link to heading

  • turbohtml — a C-accelerated HTML and URL toolkit for Python. 1.0 shipped in July; I wrote up how it works and am still widening WHATWG spec coverage.
  • peryx — a Python/Rust project under tox-dev.

Maintaining Link to heading

tox, virtualenv, pipx, filelock, platformdirs, pyproject-fmt, tox-uv, and the rest of the tox-dev and PyPA tools I help look after. Most weeks that means triage, releases, and keeping CI green. The projects page tracks the full set.

Writing Link to heading

Recent deep dives: a fast HTML toolkit in C , deterministic multithreaded testing with blanket , and securing the Python supply chain .
