So, last year, I created my first Obsidian plugin... see https://github.com/drmohundro/obsidian-igdb-game-search-plugin/. I submitted a pull request in January. Then in May, Obsidian created their new community. I sat getting my submission and... someone else had the exact same idea as me and got their plugin submitted before me.
It isn't a big deal, though. I don't have to support my plugin anymore and I can still use it on my own!
I've been building a local tool for myself to help with creating and managing git worktrees. I like using worktrees for doing parallel work with git, but the usability of them is a bit off. So now I've got a little Go-based CLI to help me with it. On top of that, I'm finally teaching myself some tmux. I've used tmux before, but I never really had a lot of use for it, but with some CLI automation, it is pretty useful.
Nice link about RSA works - see https://ente.com/blog/how-shamirs-secret-sharing-works/. Great visuals.
I've been playing around with using aube as my npm/pnpm/yarn alternative. We'll see how it goes. I like the idea of better defaults and not having my disk just be gigs of node_modules directories.
