Simon Willison TIL

Modern frontier models have got really good at using Blender.

I've started exploring MCP in more detail.

I often find myself wanting to run a quick Python tool inside of GitHub Actions using uvx name-of-tool - but I don't want that to result in a network request to PyPI every time the workflow runs.

I use Cloudflare's CAPTCHA (they call it a "Managed Challenge") on simonwillison.net/search/ to prevent crawlers from following every single possible combination of my faceted search UI.

I'm a recent convent to AgentsView, Wes McKinney's (previously of Pandas fame) Python toolkit for analyzing transcripts of coding agents from your own computer.

This comment on Hacker News inspired me to investigate patterns for using my LLM CLI tool in a shebang line: But seriously, you can put a shebang on an english text file now (if you're sufficiently brave) [...]

I've been experimenting with ways to fetch data from Datasette and display it in Google Sheets.

I'm not brave enough to run OpenClaw (aka Clawdbot aka Moltbot) directly on my Mac, so I decided to try running it in a Docker instead container.

I serve Python files from my tools.simonwillison.net subdomain, which is a GitHub Pages site that's served via Cloudflare.

I'm a big user of Claude Code on the web, Anthropic's poorly named cloud-based version of Claude Code which can be driven via the web or their native mobile and desktop applications.

I took the Neon I intensive week-long evening class at the Crucible in Oakland, with teachers Dan Kuppe and Kat.

Last February I blogged about a neat script called sqlite-s3vfs which was released as MIT licensed open source by the UK government's Department for Business and Trade.

pytest 9.0.0 was released on November 8th 2025.

I've adopted a new (to me) pattern for my Python projects to make them easier to hack on using uv run.

I've written about the DGX Spark before.
