Logseq is a pretty nice FOSS alternative to Obsidian I came across recently. Tmux is absolutely necessary for any terminal work. Wezterm is my favorite terminal emulator because you can easily disable all of the shortcuts except very few you want (tmux handles most of terminal stuff for me). Some new alternatives to old command line utilities:
bat is cat but 1000 times better. I love it so much!
fun factI also recently learned that it’s safer, because you can have a file that has some bad command, then the backspace character several times, and cat doesn’t display the characters “deleted” by the backspaces (but it still executes). Bat doesn’t do that.
