Pimsleur. It’s very different than Duolingo, in that it is almost entirely audio-based. However, at least in my experience, it actually gets you to the point of speaking and understanding a language much more rapidly than Duolingo. Way, way less gamified though. It expects you to put in half an hour a day where you just concentrate on the lesson.
Neovim, because I wanted something that would not just disappear.
I never really got along with VSCode, opting for Atom instead. Microsoft bought GitHub, which owned Atom, and promptly discontinued it.
Nvim has such an active community (and no “owner”) that I’m certain that this won’t happen again. At the same time, the plugin system is so flexible that I’m also certain that I will never miss out on any shiny new features.
Over the years, my config has matured, and is mine. The thought of going back to an editor, any editor, less flexible in its configuration than nvim is just… an absolute “no”.
It’s a steep learning curve, but well worth it.
