Syntaqlite Playground

Syntaqlite Playground

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 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…

scan-for-secrets 0.2

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.

scan-for-secrets 0.1

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 Python scanning tool to help reassure me. You can feed it secrets and have it scan for them in a specified directory: uvx scan-for-secrets $OPENAI_API_KEY -d logs-to-publish/ If you leave off the -d it defaults to the current…

research-llm-apis 2026-04-04

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,…

[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. — Kyle Daigle, COO, GitHub Tags: github, github-actions

Vulnerability Research Is Cooked

Vulnerability Research Is Cooked

Vulnerability Research Is Cooked Thomas Ptacek's take on the sudden and enormous impact the latest frontier models are having on the field of vulnerability research. Within the next few months, coding agents will drastically alter both the practice and the economics of exploit development. Frontier model improvement won’t be a slow burn, but rather a step function. Substantial amounts of high-impact vulnerability research (maybe even most of it) will happen simply by pointing an agent at a…

The cognitive impact of coding agents

A fun thing about recording a podcast with a professional like Lenny Rachitsky is that his team know how to slice the resulting video up into TikTok-sized short form vertical videos. Here's one he shared on Twitter today which ended up attracting over 1.1m views! That was 48 seconds. Our full conversation lasted 1 hour 40 minutes.

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…
