Have you been able to get ProtonVPN to work with WireGuard on Linux? I believe their VPN client on Linux only uses OpenVPN and I’ve tried to pull a WireGuard config file for a P2P server but every time I try to use it, I get no connection.
I second the recommendation for Professor Messer. I went through his videos when I was prepping for the A+ exam last year. An amazing resource all for free. If you’re moving forward to get Network+ and Security+ too, Messer has a whole series of videos for those as well.
Another shout-out for Sonic Robo Blast! I absolutely love that game.
