  • The most intuitive analogy to federation to me is email. You may have an account with one provider (gmail.com in the example of email, or lemmy.world in the example of Lemmy) but you can send emails to other providers (email example) or post messages to other instances (Lemmy).

    Just like with email providers, a Lemmy instance may decide not to allow communication with another instance - this is “defederation.” Instances that allow communication are “federated.”

    Just like email, you don’t normally need to worry much about whether you are on the same instance as a particular community or user - it just works.

    This is a simplification, but for me is a good working model.



  • This is clearly nonsense. Besides the fact that 1000 mph wind is not possible, the earth and atmosphere are rotating at roughly the same speed.

    Let me say it again, the earth and atmosphere are rotating at roughly the same speed. This is obvious.

    The lack of basic education that some countries have on common physics concepts such as the rotation of the earth is shocking.

    It’s as if they teach their school children nothing but abstract concepts for 13 years, and then send them out into the world without understanding how relative velocity works, or how electricity works, or how a computer works, or their nation’s laws and their rights as citizens and workers, or… anything, really.

    For all that education, people seem to leave school completely unprepared for the real world. They are let down by the system. It’s sad to see.
