Unserious #ThoughtProvoker of sorts..

How about letting #AI - guided along by some protocol experts to formulate good prompts - maintain and evolve the open standard specs based on all the info the AI has sucked up from all the FOSS projects that are implementing #ActivityPub.

(Note that I am wary of AI for a whole host of reasons, mostly all relating to its disruptive introduction and its potential dehumanising effect, eroding social cohesion and connection between people.)

Fediverse & AI Coding Tools & Vibe Coding

...

I noticed 2 or 3 people lately using AI coding tools to create Fediverse software.

2 of them even seemed to be Vibe Coding.

...

I have been programming for over 30 years. I am probably not going to Vibe Code, but —

I wonder if we should help them.

There are tools we (Fediverse developers) could create to make it so others could Vibe Code Fediverse apps.

Yes, help them.
No! (explain why in comments)

#snac, el más mejor servidor #activitypub del mundo mundial. Escrito en lenguaje C, el único y verdadero, es del tipo "instalar y olvidar" porque no da problemas y ocupa un mínimo de RAM y apenas CPU. Software como se hacía antes: óptimo.

If we enumerate possible design choices there are thousands of possible social media platforms - but is anyone actually good?

Are better experiences to be found within this vast configuration space or do we need a more fundamental rethink?

And how can we go about finding out?

Cryptographic public-keys are one way that one can have an identity (on the Fediverse, and elsewhere) while also having privacy — through a pseudonymous identity.

Yes, we have Fediverse IDs such as:

@joeblow@example.com

But a (non-delegated) public-key can function as a PORTABLE form of identity on the Fediverse.

All that requires that a Fediverse user can have multiple public-keys specified for them.

...

Although w3id.org/security/v1 seems to allow for multiple public-keys —

I wonder how much Fediverse software could actually handle multiple public-keys (rather than just one)?

(And, don't just assume one public-key?)

2/

To handle public-key cryptography safely, often a user should be able to have multiple public-keys.

For example, a user might have a different public-key on each device, rather than sharing public-keys.

A user might delegate to a 3rd party — and there may be a delegated versus non-delegated public-key distinction.

Key-rotation is also often necessary for safety reasons.

Etc.

1/

One way ActivityPub can be extended is — through JSON-LD namespaces.

For example, many Fediverse servers use the following JSON-LD namespace to specify cryptographic public-key(s) for the user.

w3id.org/security/v1

(This particular namespace is an HTTPS URL.)

...

But, does extant Fediverse software support cryptographic public-key(s) well?

This is another attempt at uploading media via my custom app. If you see the image below, iQon is coming soon.

ActivityPub, the protocol that powers much of the fediverse and allows the various fediverse platforms and servers to talk to each other, has become an official W3C standard 8 years ago!

Parece ser que ha llegado el momento.

Combate a muerte🤣 ; #ActivityPub vs #ATProtocol.

O quizá son complementarias 🤔.
