Ask HN: What dev tools do you rely on that nobody talks about?
https://github.com/atuinsh/atuin for fuzzy shell history (ctrl+r)
https://github.com/sharkdp/bat (nice coloured cat replacement)
https://github.com/abiosoft/colima (so I don't need docker desktop)
https://github.com/duckdb/duckdb (performant database that lets you directly query JSON, parquet, csv files with SQL queries and convert one to the other.
https://github.com/eradman/entr (rerun commands automatically when provided files change) (useful for rerunning test commands automatically once you save the file you're editing.
https://github.com/martinvonz/jj and https://github.com/idursun/jjui (Jujutsu VCS, been using it for three months and I really enjoy it)
https://github.com/jesseduffield/lazydocker (managing containers, images, volumes easily)
https://github.com/jesseduffield/lazygit (best tui for git and outside niche git commands, the fastest way to use git.)
https://github.com/jdx/mise (fast asdf, direnv, and task runner replacement) (install pretty much version of tool, language, env vars in a per directory level. (Or global if you want))
https://github.com/ajeetdsouza/zoxide (intelligent cd to move between directories incredibly quickly)

Detecting file changes on macOS with kqueue
I love small personal projects like this, especially their writeups. I always have a hard time learning unless I am actually using it for something.

Building Bubbletea Programs
This is the same TUI app workflow I've settled on in other languages. Three notes:
- entr is a good livereload tool: https://eradman.com/entrproject/. I prefer to wrap the livereload scripts in a Makefile, under something like `make dev`.
- Managing layout arithmetic by yourself is a real pain. A widget abstraction like Bubbletea's is very helpful. Also, don't forget about weird Unicode characters (eg. emoji) potentially breaking width calculations.
- Since this follows the Elm architecture, consider storing your data the Elm way into one big, flat Model. Elm webapps turn into headaches when you split state among submodels. I think the same happens in TUI apps. I'm glad the author found a solution with a tree of models and message passing. But personally, I'd rather have a Model with 100 fields than the complexity of sumbodels.

Simple Directory Watcher to Restart Dev Server
Do I really need a whole Go library to do that? There must be a lighter or in other words Linux solution. I came across few solutions but not all had the capability to handle all types of directory changes. I wanted to be able to watch for file: create, edit, move, delete. For example entr doesn't rerun the command when a new file is added to the directory that is being watched.
