Ever since Golden Gate Claude I’ve been fascinated with “steering”: the idea that you can guide LLM outputs by directly manipulating the activations of the model mid-flight. DeepSeek V4 Flash I was inspired to write this post by antirez’s recent project DwarfStar 4, which is...

I built ZIP Shrinker, a little browser tool to shrink ZIP files. It also works with formats that are secretly ZIPs underneath, like EPUB, JAR, and many more. Try it out! How does it work? At a high level, this tool (1) re-compresses every file in the ZIP archive with higher ...

Let me share a very silly story from roughly 18 years ago! In 2008, I joined RSA, the network security company named after the initials of the inventors of the RSA algorithm, Rivest, Shamir and Adleman, who were also the founders of RSA, the company. There ...

Tool: QR code generator

Claude helped me build this tool for creating QR codes, for both text/URLs and for connecting to WiFi networks.

AlphaGo is still the cleanest worked example of the primitives of intelligence: search, learning from experience, and self-play.

This Mitchell Hashimoto quote about Bun migrating from Zig to Rust reminded me of a similar conversation I had at a conference last week. I was talking to someone who worked for a medium sized technology company with a pair of legacy/legendary iPhone and Android apps. They t...

[...] On the interesting side is how fungible programming languages are nowadays. Programming languages used to be LOCK IN, and they're increasingly not so. You think the Bun rewrite in Rust is good for Rust? Bun has shown they can be in probably any language they want in roughly a week or two. Rust is expendable. Its useful until its not then it can be thrown out. That's interesting!

I didn’t expect DwarfStar 4 (https://github.com/antirez/ds4) to become so popular so fast. It is clear that there was a need for single-model integration focused local AI experience, and that a few things happened together: the release of a quasi-frontier model that is large ...

Release: datasette-agent 0.1a1

• Now uses the execute-sql permission when deciding which tables to list to the user. #8

Thanks for giving me a viable business model Amazon!

Release: datasette-ip-rate-limit 0.1a0

The datasette.io site was being hammered by poorly-behaved crawlers, so I had Codex (GPT-5.5 xhigh) build a configurable rate limiting plugin to block IPs that were hammering specific areas of the site too quickly.

Here's the production configuration I'm using on that site for the new plugin:

  datasette-ip-rate-limit:
    header: Fly-Client-IP
    max_keys: 10000
    exempt_paths:
    - "/static/*"
    - "/-/turnstile*"
    rules:
    - name: public-demo-multi-parameter-table-pages
      paths:
      - "/global-power-plants/*"
      - "/legislators/*"
      window_seconds: 60
      max_requests: 60
      block_seconds: 20

Yesterday I attended the first assembly of the Democratic Tech Alliance (DTA), which gathered in the European Parliament. Membership of the alliance includes European political groups like the Greens/EFA, the liberal/center right Renew Europe, the European People’s Party of Christian democratic, conservative and liberal-conservative persuasion and also the Progressive Alliance of Socialists and Democrats.
This is a broad, quite sane and actually impressive collection of political groups, which gives me some hope.

If Byron Allen shows up at your door, you did something wrong with your media business. And BuzzFeed has a visitor. Also: I built a thing.

Welcome to the Datasette blog

We have a bunch of neat Datasette announcements in the pipeline so we decided it was time the project grew an official blog.

I built this using OpenAI Codex desktop, which turns out to have the Markdown session transcript export feature I've always wanted. Here's the session that built the blog. See also issue 179.
