#activitypubprotocol — Public Fediverse posts

@Ulli
-->2:
Das #ActivitypubProtocol des #Fediverse sieht zwar vor, dass man sich mit einem einzigen #Account überall anmelden kann, aber es hängt von den #Instanz-Betreibern ab, ob sie diese Option auch aktiveren. Darin liegt der Wurm, den Du zurecht bemängelst.

Half-joke half-serious #activitypubprotocol rant

Why doesn't #ActivityPub just use ASN.1 DER?

It has
- Deterministic encoding and thus not a night mare to sign and check
- More compact and not have to do at least 2 pass and 2 buffers (not counting data structure overhead) to de-serialize a document.
- Separation of concerns in field representation, binding and canonicalization
- Good historical support in almost any language.
- Actually can de-serialize as you receive data, not having to save what could be megabytes of JSON and at the end receive a @context and suddenly have a lot of computational work and say hang on a bit I have no idea what you are talking about.
- Uses real identifiers not URL for everything, even W3C's own JsonLD schema broke

To me it feels like nobody is adopting it (IMO for good reasons, "infinite extensibility" has costs in efficiency and integrity) so W3C has to use it in #activitystreams. I feel Json-LD is more suitable for immutable archive (backups, tape, etc) when future needs are absolutely not predictable and changing the schema must be done without changing the original data, not here.

It makes no sense

Whenever anyone tells me that some platform is great, I always nod and think to myself … for now. For now.

I don’t understand why no one else is saying this: Until I see anyone else running separate federation instances, it’s still just another monolithic platform. This again? If the AT Protocol (what Bluesky is built upon) is really great, how do I run my own instance to join the federation?

If you see only one instance, then it’s a platform. When you see multiple instances talking to each other, then it’s a protocol.

Und man denkt sich: warum nicht einfach eigene auf Activity Pub basierende Instanzen hosten statt den proprietären Schrott von #Bluesky zu übernehmen?

I’ve had this idea of the ActivityPub Protocol powering Mastodon, Threads, & others in The Fediverse, as a kind of Rube-Goldberg Machine.

What kind of Rube-Goldberg Machine ?

The MouseTrap Boardgame from childhood !

I captioned the following images to get the idea out of my head.

Hi #all,
I created this #mastodon space for me because I strongly believe in #opensource and #selfhosting. Internet should stay a network of network. I think the #fediverse and #activitypubprotocol is a good layer that allow it to do so for social interaction.

#freespeech is essential but #hatespeech and #FUD is not.

I love #opensource, #linux, #radio, #space, #travel and #food. I also love #computers and #humans.
I try to keep it "#simple" and "#slow".

Glad to be here !
