The web can be made personal again.

Personal data storage is an idea whose time has come

Data Ownership as a conversation changes when data resides primarily with people-governed institutions rather than corporations.

Joshua Rogers, using AI tooling responsibly and professionally, reported 22+ genuine issues in curl that are now being addressed

Especially notable because curl had problems with floods of garbage slop AI "security issues" in the past that were nothing of the sort simonwillison.net/2025/Oct/2/c...

Joshua Rogers sent us a *massive* list of potential issues in #curl that he found using his set of AI assisted tools. Code analyzer style nits all over. Mostly smaller bugs, but still bugs and there could be one or two actual security flaws in there. Actually truly awesome findings.

I have already landed 22(!) bugfixes thanks to this, and I have over twice that amount of issues left to go through. Wade through perhaps.

Credited "Reported in Joshua's sarif data" if you want to look for yourself

We are alarmed by reports that Germany is on the verge of a catastrophic about-face, reversing its longstanding and principled opposition to the EU’s Chat Control proposal which, if passed, could spell the end of the right to privacy in Europe. signal.org/blog/pdfs/ge...

Great customer support is important, but I think great self-serve support is even more.

- Intuitive product UI.

- Inline UI microtexts that help customers without sending them away from their task at hand.

- Clear, up-to-date, easy to search text docs.

- Video guides

Most of the "90% of code written by AI" claims come from vendors selling AI tools and lack credibility as a result

Armin (creator of Flask, Jinja, Click) is different - when he says 90% of a new significant infrastructure project he's building was AI generated that's worth paying attention to

My oldest and me are making a 3d printed bb8. So far we didn't make it very far, but we wanted to spray paint it, so I needed a cutout. Turns out Claude Code is great at writing OpenSCAD files. Still kinda blown away.

Made some notes on the new DeepMind paper "Video models are zero-shot learners and reasoners" - it makes a convincing case that generative video models are to vision problems what LLMs were to NLP problems: single models that can solve a wide array of challenges simonwillison.net/2025/Sep/27/...

EU–INC is the single best thing Europe could do to catch-up in the AI race

A simple unified pan-European startup structure, with modern employee ownership and simple access to capital, able to tap into Europe’s full talent pool.

This is such a great explanation (and visualization) of the @atproto.com ecosystem and why it is working ♥️

I strongly believe in this protocol and it's future. Let's build it together 💪🏻

Postgres 18.0 was just released!

What does it mean for Oban? Glad you asked:

- Asynchronous I/O for improved scans
- Skip scans for multi-column B-Tree indexes
- Parallel builds of GIN indexes
- Improved vacuum strategy
- Many optimizer improvements
- Native UUIDv7 data type
