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!
Their “data tracking” was just telemetry to figure out what buttons people were actually pressing.
I use Ocenaudio for quick audio edits anyways.
All the same, I did switch to Ocenaudio when I heard the news. Works pretty good.
