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 fast, open-source artifact vault for multiple ecosystems (PyPI and OCI today), written in Rust.

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. My Open Source 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 .
