They can be cross platform, but please don’t post boring things like powertop, Firefox, or LibreOffice
I’ll go first:
LyX (sort of LaTeX WYSIWYG document editor- primarily for academic stuff)
Joplin (open source markdown/katex note application, interface is similar to Notion)
Mint’s webapp-manager utility, because I have to do alot of stuff in OneDrive for school and the two native OneDrive clients on Linux are kind of sus, and I like to open this separate (and save my password) from my normal Firefox window.
zellij: Prevents sessions from dying when my SSH connections drop-- very handy. nnn: Simple, easy to use file manager. Also good for navigation, when set up to cd on exit. nix: I can get pretty much any other package I need with this.
Hmm…There are a bunch more than these, but I think the following are more valuable to me as they are useful to help me earn money.
tmux: Along with tpm and some common plugins, I spend most of my time on the terminal. I use it along with neovim and other tools to get things done for work and personal projects.
git + glab: Work repos are managed on gitlab. I use glab for managing issues, creating merge requests, and with some custom scripts I keep the many repos synced locally.
My slightly useful, but really just fun bonus tool:
btop++: It looks so cool, but my wife is unimpressed ( ¯_(ツ)_/¯). It’s prettier and more useful than htop. I used ytop, but that is an archived project, I believe.
Firefox? Boring? You should see my setup!! At least it’s pretty much indispensable, it’s how I’m typing here!
More seriously, I guess I’m really a boring old dude, with my Emacs doing almost everything… That’s what I use for Markdown, LaTeX, email (through notmuch), and coding (props to magit here).
I also use syncthing quite a bit. I’m probably forgetting half a dozen other tools I would die without, but let’s keep this short.
KeePassXC: the heart of my personal security setup
Rclone: running as a cron job once per hour to sync a few subdirectories in my home directory (including the one with my KeePassXC database) to a cloud storage service
uBlock Origin extension for Firefox: does that count?
