I’m building CmdRunner, an AI agent that executes web application test cases directly from documents.<p>Most teams maintain Selenium or Playwright scripts, but many already have test steps written in Excel or documentation.<p>CmdRunner reads those steps and performs them in a browser like a human te...

Play icons in YouTube, Spotify and Apple Music are not mathematically centered – they are optically centered. Most icon systems adjust this manually.<p>I'm collecting perceptual data to explore whether a CSS “optical-center” property could be defined, similar to how fonts have baseline metrics....
I've been a fan of Derek Sivers' /now movement (nownownow.com) for a while. The idea is simple — a page that says what you're focused on right now, not a static bio. Hundreds of people have one, but making one still means setting up hosting and writing HTML yourself. That's ...
