I’ll start by plugging Harvard’s free courses catalog as well as Udemy
Edit: Gonna add 2 more I remembered-
Blender - I wish I had more time to learn it, but I did start the infamous “Donut Tutorial” once!
Watch Cartoons Online - Lots of good older stuff!
YouTube. Duckduckgo.
Personally I’m running 13 containers for various things. Worth it.
But I googled docker, and only found apps that can be installed. Does it both require something to run the docker apps in?
