Experience report of attempting to write an ActivityPub server in OCaml.

"An ActivityPub server with an NNTP interface."

Note for implementing ActivityPub federation.

"In particular, this blog post is a direct response to forge-net (formerly known as GitPub). They want to federate and decentralize git using ActivityPub, the same technology leveraged by Mastodon and PeerTube. But get this: git is already federated and decentralized!"

Development plans for ActivityPods, a Solid / AP integration. The article also describes Mastopods which will be a Mastodon-compatible version of this code.

"We observed that most paginations are just linked or double linked lists, with sometimes a way to indicate the ordering, and/or even IRI templates with search forms or controls to change the ordering. This is not the most efficient data structure to retrieve information..."

There are four ways in which ActivityPub is a non-standard standard. This work is informed by reading the Social Web Working Group (SocialWG) meeting minutes, interviews with SocialWG members, and a study of historical documents.

Provides docker containers for Mastodon for testing purposes (and eventually others). It uses a local certificate authority with automatic SSL cert provisioning.

Command-line ActivityPub API client (C2S?)

"Unwanted messages are a challenge for all public communication systems. On a federated network without a central form of control, the challenge is extended to allowing for free communication between parties without a central means of control while at the same time preventing undesired or harmful messages."
