so much nerdy talk - I'm home <3
Yeah I'm also closing in on half my life time using *nix, and close to that self-hosting as well.
I do think that the greater understanding of all things technical.ä that I accumulated this way (and own my own, too!) greatly benefits me professionally.
Which leads me to believe that I would only know half of what I do about *nixcraft if I had used stuff like Docker or Snap right from the start.
