I still haven’t settled on what to do next, but for sure I will continue with educational material for now as I don’t have concrete goals to contribute to “real world” projects (yet). I also like having some structured path layed out for me, it makes it easier work on it every other day and not get stuck wondering what best to do next.

As for more serious projects I am interested in and could be a potential follow up to contribute to a bigger kernel, there are SerenityOS and RedoxOS.
