I've started several decades ago, with some ancient Slackware (?) version, downloaded using 56k line modem as 1.44 floppy images. Meanwhile I had a period of a difficult relationship with Windows (2000 was the least bad) and a longish affair with MacOS. Now Linux-only everywhere, for the last ~5 years.
Codeberg for all my projects, both private and public. Some are mirrored to Github. Also Codeberg Pages and its Woodpecker CI.
I don't know if it's the best, but kitty + zsh has been my daily driver for many years.
Adding
[Settings]
gtk-theme-name=Adwaita-dark
to $USER/.config/gtk-4.0
and $USER/.config/gtk-3.0
should do the trick.
SublimeText with this plugin: https://github.com/mvoidex/UnicodeMath
Despite the name, it works for all Unicode characters :)
Debian Testing. My daily driver since.. a long time :)
