Datasette is an open source tool for exploring and publishing data.

Civic Band. Exciting new civic tech project from Philip James: 30 (and counting) Datasette instances serving full-text search enabled collections of OCRd meeting minutes for different civic governments. Includes 20,000 pages for Alameda, 17,000 for Pittsburgh, 3,567 for Baltimore and an enormous 117,000 for Maui County.
Philip includes some notes on how they're doing it. They gather PDF minute notes from anywhere that provides API access to them, then run local Tesseract for OCR (the cost of cloud-based OCR proving prohibitive given the volume of data). The collection is then deployed to a single VPS running multiple instances of Datasette via Caddy, one instance for each of the covered regions.
Weeknotes: Datasette Studio and a whole lot of blogging
I’m still spinning back up after my trip back to the UK, so actual time spent building things has been less than I’d like. I presented an hour long workshop on command-line LLM usage, wrote five full blog entries (since my last weeknotes) and I’ve also been leaning more into short-form link blogging—a lot more prominent on this site now since my homepage redesign last week.
[... 736 words]Language models on the command-line
I gave a talk about accessing Large Language Models from the command-line last week as part of the Mastering LLMs: A Conference For Developers & Data Scientists six week long online conference. The talk focused on my LLM Python command-line utility and ways you can use it (and its plugins) to explore LLMs and use them for useful tasks.

A very minor dot-fix release for Datasette stable, addressing this bug where Datasette running against the latest version of SQLite - 3.46.0 - threw an error on canned queries that included :named parameters in their SQL.
The root cause was Datasette using a now invalid clever trick I came up with against the undocumented and unstable opcodes returned by a SQLite EXPLAIN query.
I asked on the SQLite forum and learned that the feature I was using was removed in this commit to SQLite. D. Richard Hipp explains:
The P4 parameter to OP_Variable was not being used for anything. By omitting it, we make the prepared statement slightly smaller, reduce the size of the SQLite library by a few bytes, and help sqlite3_prepare() and similar run slightly faster.
Ham radio general exam question pool as JSON. I scraped a pass of my Ham radio general exam this morning. One of the tools I used to help me pass was a Datasette instance with all 429 questions from the official question pool. I've published that raw data as JSON on GitHub, which I converted from the official question pool document using an Observable notebook.
Relevant TIL: How I studied for my Ham radio general exam.
datasette-pins — a new Datasette plugin for pinning tables and queries. Alex Garcia built this plugin for Datasette Cloud, and as with almost every Datasette Cloud features we're releasing it as an open source package as well.
datasette-pins allows users with the right permission to "pin" tables, databases and queries to their homepage. It's a lightweight way to customize that homepage, especially useful as your Datasette instance grows to host dozens or even hundreds of tables.
Weeknotes: more datasette-secrets, plus a mystery video project
I introduced datasette-secrets two weeks ago. The core idea is to provide a way for end-users to store secrets such as API keys in Datasette, allowing other plugins to access them.
Food Delivery Leak Unmasks Russian Security Agents. This story is from April 2022 but I realize now I never linked to it.
Yandex Food, a popular food delivery service in Russia, suffered a major data leak.
The data included an order history with names, addresses and phone numbers of people who had placed food orders through that service.
Bellingcat were able to cross-reference this leak with addresses of Russian security service buildings—including those linked to the GRU and FSB.This allowed them to identify the names and phone numbers of people working for those organizations, and then combine that information with further leaked data as part of their other investigations.
If you look closely at the screenshots in this story they may look familiar: Bellingcat were using Datasette internally as a tool for exploring this data!
