I've been on Lemmy for some time now and it's time for me to finally understand how Federation works. I have general idea and I have accounts on three federated instances, but I need some details.
Let Alpha, Beta, Gamma and Delta be four federated instances. I have an account on Alpha and create a post in a community on Beta. A persoson from Gamma comments on it and a person from Delta upvotes the post and the comment.
The question: On which instances are the post, the comment and the upvotes stored?
Not so long ago I bought my first 3D printer. It hasn't shipped yet, but I'm gathering knowledge so hopefully I'll be able to use it when it arrives.
One of the things I noticed while choosing the printer was that many specified "perfect first layer". What's so special about it? What should a beginner such as I know about it?
