SocialHub at OFFDEM

Continuing the discussion from SocialHub at OFFDEM:

Since the Decentralized Internet & Privacy Devroom at FOSDEM is set to happen on Sunday February 2nd, let’s gather for the

Caturday SocialHub at OFFDEM

Saturday, February 1st, 2020 at VSP, 15 minutes away from the Campus Solbosch.

This topic is to prepare the meeting, define the needs and wants, and see who’s up for it!

More information about OFFDEM, the Off festival of FOSDEM.

I will be attending!

Topics I would be interested in discussing:

ActivityPub for communities, social and civic organizations

How is (or could) ActivityPub be used in communities, social and civic organizations? What are the currently ongoing projects?

Related projects include:

Event Sourcing

Event Sourcing means maintaining the state of a system by tracking the sequence of changes to the system. Activities in ActivityPub are events that describe a change in the system state. To what extent can ActivityPub be seen as an event sourcing system. What is the minimal amount of state that needs to be held to implement an ActivityPub server? What is the minimal amount of state mutation that needs to be implemented?

Capability-based security

Work by @cwebber and the keynote by Mark S. Miller at ActivityPubConf 2019 have stirred my interest in capability-based security.

  • What is current state of implementing this in ActivityPub?
  • Any experiences with existing systems using capability-based security?

I’ll be attending as well.

Wanting to continue my work on decentralised hashtag federation, I’m mainly interested in the following topics:

  • representing hashtags (or their stores and relays) as ActivityPub actors
  • how to couple existing ActivityPub servers with an additional P2P proxy component
  • the existing relay implementations

Looking forward to seeing you folks there!

I will attend OFFDEM.

In general I have a strong opinion on FOSDEM which is :
Events like 36c3 seem to be a much better place to talk about ActivityPub while google and facebook takeover FOSDEM at the same time when Mozilla is kicking out 70 people and FSFE closes Düsseldorf office and other civil rights organisations like edri seem to become powerless.


is important to me and related projects also should include redaktor :wink:
We nearly have a really generic nodeJS AP server (full AP spectrum) including groups and topics etc. and do corresponding client webcomponents for CRUD to praise the AP C2S API …

from 36c3

We discussed “Awareness Formats for ActivityPub” like

  • a virtual week conf before/after Barcelona with an AskMeAnything with Chris etc.

  • Local clusters / Install Parties w. local associations, clubs, pubs, NGOs, XR

  • A placard and billboard campaign

We are in contact with journalist from the “science session” at 36c3 and with Verge and Guardian. Maybe we can plan a “closed group” …

Apart from that most key points were written already, I’d like to add some
other “most important tasks” :

  • Encouraging Multi Language Use of the protocol implementations
  • Discovery and “porting friends” (between instances)
  • Topics and Groups in ActivityPub
