I’ve been using Windows as my daily use lately despite I have been using Mac/Linux for a long time, but I keep running into all sorts of issues, so I’ve been fixing them vibe-coding with Claude. I’m gonna dump all that stuff on This blog is fully automated with Claude Code, from coding all the way to reporting. It’s nothing special—anyone could do it—but it’s actually pretty fun once you try it. The only annoyed is that it burns through tokens like crazy.
