✸ We have the pleasure of having Hong Minhee (洪民憙) who will give a presentation about Fedify ❝an opinionated ActivityPub framework for TypeScript that handles the protocol plumbing. Implementing ActivityPub looks simple at first—it’s just JSON over HTTP, right? Then you hit JSON-LD context resolution, HTTP Signature verification that fails on some servers but works on others, and specs spanning hundreds of pages that every implementation interprets differently. I’ll cover type-safe vocabulary, comprehensive signature support, framework-agnostic design, and the CLI toolchain—plus production stories from Ghost, Hollo, and Hackers’ Pub.❞

❋ Anarchaia: 20 years after

by Leah Neukirchen

❝The weblog Anarchaia has been widely regarded as the first so-called "tumblelog", which started a microblogging trend. But was it really the first? And what is its legacy, 20 years after its creation?❞

(they posted presentation slides afterwards)

✸ Privacy Expectations in Federated Protocols

by Fiona Fokus

❝Exemplified by the recent Pixelfed vulnerability I'll summarize how incomplete or wrong ActivityPub implementations can violate our expectations on how privacy is treated. Afterwards there is room for an open discussion on how to handle these problems on a protocol and community level.❞

Raphael Lullis will talk about Fediverser, how it currently integrates with Lemmy & its future plans.

Bumblefudge will give an overview of ways to make ActivityPub easier to hack on and more bridgeable to p2p systems, & talk about their participation with the W3C.

Gábor Ugray created RSS Parrot because he wanted to follow RSS feeds in Mastodon & because it was a good excuse to write his own ActivityPub server in Go. He'll talk about the technology, his fears & desires he's encountered in the process.
