Read this post for a quick discussion.
The current tools
ArchLinux, the Sway compositor, and the fish shell.
Kakoune for file editing, Firefox with the Tab Center and Vimium extensions (and Zotero and other standard stuff) for browsing.
Emacs with mu4e for emails, Pelican for blogging.
Jupyter with Python's and Julia's scientific ecosystems, Elm, and git. Hopefully a lot more of, soon, Rust and Racket.
Orgmode with org-protocol to capture permanent and dated notes, and Hamster to track time spent on tasks and keep a good overview of work hours.
Interface and incentives
The Dvorak keyboard layout. A family to push me to take regular breaks so I don't go blind because of too much screen, and Redshift so that said screen stays comfortable at all hours of the day and night.
