Armin Ronacher's personal blog, running since the late 2000s. He created Flask and Jinja2, co-founded Sentry, and (as of 2026) is building Pi β a coding-agent platform. The blog mixes Python ecosystem opinion, infrastructure essays, language-design takes (Rust, Zig), and increasingly LLM-product perspectives.
The 2026 posts skew toward making local LLMs and agent tooling actually usable β see lucumr-local-models for his take on stack fragmentation and the pi-ds4 extension wrapping antirez's ds4.c. He also co-evangelizes the titit-local-ai line of argument: cloud LLM economics and locality concerns are pushing serious builders toward open-weights local stacks, but the UX needs work before that's a usable position for anyone outside the experimenter caste.
Each post offers a markdown view (the /path/to/post.md URL works as the canonical source for ingestion).
