SE Radio 657: Hong Minhee on ActivityPub and the Fediverse

Hong Minhee, an open source developer and
creator of the Fedify ActivityPub library, discusses the
ActivityPub protocol and the fediverse with SE Radio's Jeremy
Jung. They explore ActivityPub use cases, including microblogging
applications such as Mastodon and Misskey, as well as activities
built into the specification such as Like, Follow, and Accept.
They also discuss extending the specification to include
properties like Discoverable and Suspended, how different
implementations communicate when they don’t implement the same
extensions, ND the use of JSON-LD and why it is challenging to
implement. Finally, they consider the HTTP-based inbox
communication model, difficulties with scaling when using a push
rather than a pull model, account migration, and resources for
implementing the ActivityPub specification.
