The big feature in release v3.2.2 of Ktistec is pinned posts with support for the Mastodon Featured Posts collection. Federation works both ways—pin a post on Ktistec and it will show up as a pinned post on Mastodon and vice versa. When you refresh an actor profile, Ktistec also fetches and updates the actor's pinned posts. This is another small step in the direction of supporting all features that Mastodon-compatible client applications expect to access via the API. It's also useful in its own right.

The other major feature, which I posted a short video demonstrating here, is X-Ray Mode. X-Ray Mode is a developer and power-user tool for inspecting ActivityPub JSON-LD representations of actors, objects, and other content. Pressing Ctrl+Shift+X on any page displays the data behind the page—like an x-ray. You can:

This feature is useful for debugging federation issues, understanding ActivityPub structures, and verifying how content is stored and represented.

Here's the full changelog for the release:

Added

Changed

The next release will focus on smaller features and bug fixes.

Enjoy!

Oltre a Mobilizon esistono anche altri software che gestiscono eventi federati come Gancio e come lo stesso Wordpress attraverso il plugin Eventi per #Activitypub

Ricordo infine che gli eventi Mobilizon possono essere visualizzati e accettati anche da piattaforme come Friendica

I think I have identified a fairly significant flaw in how the #Fediverse currently operates. Hear me out.

The Fediverse currently consists of all sorts of different systems - #Mastodon, #Friendica , #Pixelfed , #PeerTube, #BookWyrm , and so forth. And while they are all connected via the #ActivityPub protocol, they all have different functionalities and different ways of presenting themselves. Which is as it should be, because Diversity Is Our Strength(TM).

However, it is here that the ActivityPub-based interactivity hits its limits - for usually, you can either experience the relevant system as it was intended, or you can interact with it, but not both - _unless_ you have an account on the same system (though not necessarily on the same instance).

Let's say that you are a Mastodon user who looks at another person's BookWyrm page. You scroll through their books, posts, and comments. Then you see some comment you want to comment on yourself, but can you do so?

Not directly. You need to figure out the URL of their comment, and then copy and paste that comment into the search bar of your Mastodon instance. Then it will show up in the same format as a Mastodon post, and you can interact with it - boost it, like it, comment on it.

Sure, it works, but it's a whole lot of tedious effort.

Or you can search for the user account in Mastodon and scroll through all their posts and comments as if they were a Mastodon user - and thus, you will miss out on all the unique user interface features of BookWyrm.

So what is missing?

Well, Mastodon already has an "Open original page" feature when looking at someone's post. What we need is an "Open original page AND AUTHENTICATE" feature. This way, the target instance (whatever software they are using) could acknowledge the viewer as an external user who could nevertheless fully interact with the local user interface, including the ability to boost, like, and make comments.

This is something that should be theoretically possible to implement, right? #FediHelp

I see quite some posts on the topic of #monetisation on the #Fediverse. My opinion, in its simplest form, is that #ActivityPub connects people. In open, transparent and, yes, free ways. Think of AP as TCP/IP, but for people.

With that in mind, note that TCP/IP itself has no features for monetisation. That is done on top of the protocol. This is how I would like to see monetisation in the fediverse too. As a separate thing on top of AP, never as inherent part of AP. My 2 cents (pun intended)

@juergen_hubert i think most of the things you mention can already be archived.
WordPress supports #activitypub and scheduled posting. Self hosting is a thing here, that way you can bundle the tools that you need to set up shop.

Someone could start a dedicated marketplace instance to distinguish business accounts.

Imo a free (!) market place could be a great addition to the #fediverse

"sharedInbox endpoints SHOULD also be publicly readable OrderedCollection objects containing objects addressed to the Public special collection..."
w3.org/TR/activitypub/#sharedI

I disagree with this SHOULD, would downgrade to a MAY.

Minor, mainly because consider a small instance, whose users do not show their Following collections, this could basically leak who the follows are.

That said, I haven't found any Software that does have a publicly readable sharedInbox!

Are there any combination #ActivityPub servers and #ATProto PDSs?
So one can post on both networks simultaneously?

One thing I have learned about the Fediverse:

If freedom of speech matters to you, and you dislike hate speech, choose a Fediverse site in Asia.

This does not give you the right to be rude. It does give you the freedom to speak honestly.

You can also respectfully disagree with others without being punished for having a different opinion. But always be respectful — never forget that.

Has anyone evaluated headless #activityPub servers? I'm thinking of something that could be used with Ghost subscriptions giving posting access to a site forum and blog comments. I suppose it doesn't have to be truly headless as long as there's some sort of authentication API.

Australian ban on under16s social media

From the Fediverse community feed on Lemmy.ml: submitted by abeorch to fediverse2 points | 1 comments- Ive been spending alot of time driving lately and I heard again about the impending ban on social media for under 16yo children in Australia.
It made me wonder whether there is as opportunity/ use case for #ActivityPub based solutions that allow schools / community groups to offer accounts to their parents - that could be
