Tool: SQLite Query Result Formatter Demo

See my notes on SQLite 3.53.0. This playground provides a UI for trying out the various rendering options for SQL result tables from the new Query Result Formatter library, compiled to WebAssembly.

I think it's non-obvious to many people that the OpenAI voice mode runs on a much older, much weaker model - it feels like the AI that you can talk to should be the smartest AI but it really isn't. If you ask ChatGPT voice mode for its knowledge cutoff date it tells you Apri...

Tool: GitHub Repo Size

GitHub doesn't tell you the repo size in the UI, but it's available in the CORS-friendly API. Paste a repo into this tool to see the size, for example for simonw/datasette (8.1MB).

Release: asgi-gzip 0.3

I ran into trouble deploying a new feature using SSE to a production Datasette instance, and it turned out that instance was using datasette-gzip which uses asgi-gzip which was incorrectly compressing event/text-stream responses.

asgi-gzip was extracted from Starlette, and has a GitHub Actions scheduled workflow to check Starlette for updates that need to be ported to the library... but that action had stopped running and hence had missed Starlette's own fix for this issue.

I ran the workflow and integrated the new fix, and now datasette-gzip and asgi-gzip both correctly handle text/event-stream in SSE responses.

Meta announced Muse Spark today, their first model release since Llama 4 almost exactly a year ago. It's hosted, not open weights, and the API is currently "a private API preview to select users", but you can try it out today on meta.ai (Facebook or Instagram login required)...

I have a feeling that everyone likes using AI tools to try doing someone else’s profession. They’re much less keen when someone else uses it for their profession.

Research: SQLite WAL Mode Across Docker Containers Sharing a Volume

Inspired by this conversation on Hacker News about whether two SQLite processes in separate Docker containers that share the same volume might run into problems due to WAL shared memory. The answer is that everything works fine - Docker containers on the same host and filesystem share the same shared memory in a way that allows WAL to collaborate as it should.

GLM-5.1: Towards Long-Horizon Tasks Chinese AI lab Z.ai's latest model is a giant 754B parameter 1.51TB (on Hugging Face) MIT-licensed monster - the same size as their previous GLM-5 release, and sharing the same paper. It's available via OpenRouter so I asked it to draw me ...

Anthropic didn't release their latest model, Claude Mythos (system card PDF), today. They have instead made it available to a very restricted set of preview partners under their newly announced Project Glasswing. The model is a general purpose model, similar to Claude Opus 4...

Release: datasette-ports 0.2

• No longer requires Datasette - running uvx datasette-ports now works as well.
• Installing it as a Datasette plugin continues to provide the datasette ports command.

Tags: datasette

Release: scan-for-secrets 0.3

• New -r/--redact option which shows the list of matches, asks for confirmation and then replaces every match with REDACTED, taking escaping rules into account.
• New Python function redact_file(file_path: str | Path, secrets: list[str], replacement: str = "REDACTED") -> int.

Tool: Cleanup Claude Code Paste

Super-niche tool this. I sometimes copy prompts out of the Claude Code terminal app and they come out with a bunch of weird additional whitespace. This tool cleans that up.

Release: datasette-ports 0.1

Another example of README-driven development, this time solving a problem that might be unique to me.

I often find myself running a bunch of different Datasette instances with different databases and different in-development plugins, spreads across dozens of different terminal windows - enough that I frequently lose them!

Now I can run this:

datasette install datasette-ports
datasette ports

And get a list of every running instance that looks something like this:

http://127.0.0.1:8333/ - v1.0a26
  Databases: data
  Plugins: datasette-enrichments, datasette-enrichments-llm, datasette-llm, datasette-secrets
http://127.0.0.1:8001/ - v1.0a26
  Databases: creatures
  Plugins: datasette-extract, datasette-llm, datasette-secrets

Tool: Syntaqlite Playground

Lalit Maganti's syntaqlite is currently being discussed on Hacker News thanks to Eight years of wanting, three months of building with AI, a deep dive into exactly how it was built.

This inspired me to revisit a research project I ran when Lalit first released it a couple of weeks ago, where I tried it out and then compiled it to a WebAssembly wheel so it could run in Pyodide in a browser (the library itself uses C and Rust).

This new playground loads up the Python library and provides a UI for trying out its different features: formating, parsing into an AST, validating, and tokenizing SQLite SQL queries.

Release: scan-for-secrets 0.2

• CLI tool now streams results as they are found rather than waiting until the end, which is better for large directories.
• -d/--directory option can now be used multiple times to scan multiple directories.
• New -f/--file option for specifying one or more individual files to scan.
• New scan_directory_iter(), scan_file() and scan_file_iter() Python API functions.
• New -v/--verbose option which shows each directory that is being scanned.

Release: scan-for-secrets 0.1.1

• Added documentation of the escaping schemes that are also scanned.
• Removed unnecessary repr escaping scheme, which was already covered by json.

Release: scan-for-secrets 0.1 I like publishing transcripts of local Claude Code sessions using my claude-code-transcripts tool but I'm often paranoid that one of my API keys or similar secrets might inadvertently be revealed in the detailed log files. I built this new P...

Release: research-llm-apis 2026-04-04

I'm working on a major change to my LLM Python library and CLI tool. LLM provides an abstraction layer over hundreds of different LLMs from dozens of different vendors thanks to its plugin system, and some of those vendors have grown new features over the past year which LLM's abstraction layer can't handle, such as server-side tool execution.

To help design that new abstraction layer I had Claude Code read through the Python client libraries for Anthropic, OpenAI, Gemini and Mistral and use those to help craft curl commands to access the raw JSON for both streaming and non-streaming modes across a range of different scenarios. Both the scripts and the captured outputs now live in this new repo.

[GitHub] platform activity is surging. There were 1 billion commits in 2025. Now, it's 275 million per week, on pace for 14 billion this year if growth remains linear (spoiler: it won't.)

GitHub Actions has grown from 500M minutes/week in 2023 to 1B minutes/week in 2025, and now 2.1B minutes so far this week.

On the kernel security list we've seen a huge bump of reports. We were between 2 and 3 per week maybe two years ago, then reached probably 10 a week over the last year with the only difference being only AI slop, and now since the beginning of the year we're around 5-10 per day depending on the days (fridays and tuesdays seem the worst). Now most of these reports are correct, to the point that we had to bring in more maintainers to help us.

And we're now seeing on a daily basis something that never happened before: duplicate reports, or the same bug found by two different people using (possibly slightly) different tools.

The challenge with AI in open source security has transitioned from an AI slop tsunami into more of a ... plain security report tsunami. Less slop but lots of reports. Many of them really good.

I'm spending hours per day on this now. It's intense.

Months ago, we were getting what we called 'AI slop,' AI-generated security reports that were obviously wrong or low quality. It was kind of funny. It didn't really worry us.

Something happened a month ago, and the world switched. Now we have real reports. All open source projects have real reports that are made with AI, but they're good, and they're real.

Research: Can JavaScript Escape a CSP Meta Tag Inside an Iframe?

In trying to build my own version of Claude Artifacts I got curious about options for applying CSP headers to content in sandboxed iframes without using a separate domain to host the files. Turns out you can inject <meta http-equiv="Content-Security-Policy"...> tags at the top of the iframe content and they'll be obeyed even if subsequent untrusted JavaScript tries to manipulate them.
