I started using Helix editor a while back, and it hasn’t disappointed yet. One important thing I’ve not yet got to work is Python debugging, so for that I usually switch over to VSCode or PyCharm. Otherwise a very good editor.

Feels like a font issue. Do you have e.g. nerdfont installed and in use in your terminal? You could check the config for plugins that makes that style, and check which fonts are in use. Could also be powerline fonts that are needed: https://github.com/powerline/fonts

For me, Andreas Kling and his work on the SerenityOS and Ladybird browser is enjoyable to watch. I recommend watching the JIT-series, Jakt-series (his and JT’s programming language they created). Actually all the series on the channel are great 😄 Also JT’s videos on Nushell and his series on the NES-emulator written with Jakt are good.

Vikunja is one option. Selfhosted, open source and Trello-like.

Jeez, I had forgotten all about LORD! Thanks for bringing back such good memories! I used to play it all the time back in the good ol’ days.
