Ask HN: Most interesting tech you built for just yourself?

I'm slightly embarrassed that in terms of building personally relevant things, my proudest (digital) work is always shell scripts I use daily. Most of my personal projects are non-technical meat-space things like building with wood and the like. Here's some that I've open-sourced:

- A git interface using fzf that works pretty nicely and is very composable. https://github.com/bigH/git-fuzzy

- An interactive evaluator, perfect for interactive `sed`, `grep`, `jq`, etc. If properly configured, it'll keep history per command or using whatever key you give it. I find myself using it often with `jq`. https://github.com/bigH/interactively

There are many other shell functions/scripts that are interesting from my `dotfiles`. Particularly interesting snippets for anyone who wants them:

- A recursize `which` that follows symlinks and stops at a real file. https://github.com/bigH/dotfiles/blob/3d48792b4e910d2fc82504...

- A `watch` alternative that runs in the current shell. https://github.com/bigH/dotfiles/blob/3d48792b4e910d2fc82504...
