   "Git who" – A new CLI tool for industrial-scale Git blaming▲252

   I've always wanted a better way to explore the authorship data embedded in a Git commit log. I'm having fun building a CLI tool to do this.

If you get a chance to try it out, please let me know. I'd love to hear feedback and suggestions. Thank you!

    RepoSweeper▲57

    I built this in 2018 as a school project to bulk delete GitHub repos. It got 25k views on Medium and ~10k users organically, then I basically ignored it for years. Recently I dug into GitHub's community discussion board and some low hanging fruit for feature additions — archive, visibility changes, collaborator cleanup. GitHub's answer was always "use the API." So I built the UI. RepoSweeper now does: - Bulk archive / unarchive - Bulk visibility (public ↔ private) - Bulk collaborator add/remove - Staleness scoring so you know what to act on first - Handles 100+ repos with…
