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!
Tenacity is a decent (not perfect) Audacity replacement.
Is that a fork of Audacity? I think I remember reading about that around the time of the hullabaloo…
Yep it is.
