Ask HN: What are you working on? (July 2025)
I’m copying the Puppeteer / Playwright client API to run in a Chrome extension using the native Chrome extension APIs. It is possible to run Playwright inside a Chrome extension, however, it requires the Chrome DevTools Protocol (CDP) to automate a browser which really hurts the user experience, is very slow, and opens security vulnerabilities.

Claude Code Is a Slot Machine
…but the odds are better Claude Code keeps me waiting. Here I am pressing return like a crack-addicted rodent in a lab. “Yes, I want to make this edit.” I watch as it works, glassy-eyed and bored as the code scrolls by, and on the edge of my seat because my ideas are about to […]

The JJ VCS workshop: A zero-to-hero speedrun
Become a Jujutsu Master in 1 hour Perhaps you’ve heard of the JJ VCS, a new VCS replacing git that makes commit discipline and dealing with stacked PRs a breeze. Perhaps you’ve read the same blog posts I have, about how great jj is and how easy it is to get started. But it wasn’t […]
Formal specs as sets of behaviors
Amazon’s recent announcement of their spec-driven AI tool, Kiro, inspired me to write a blog post on a completely unrelated topic: formal specifications.
