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!
Syncthing.
Connect any two devices’ folders together wirelessly, from anywhere.
Don’t have a server? You don’t need one. Every device is an individual node.
Backup? If you do have a server, offload some of your content and keep on rolling, or set scripts to move files by age.
Oh wow! Thank you for sharing it! Glad to see there are still useful and free to use utilities available.
commenting to remind myself about syncthing for when I can look into it later.
