Emissary along with @Bonfire and @swf are working on #MLS based e2ee messaging over #ActivityPub supported by Sovereign Tech Fund

On stage now, @django — arguing for widespread adoption of ActivityPub client-server (C2S) protocol.

I agree with him.

At the very least, to make extension of ActivityPub through JSON-LD namespaces possible.

But also to decouple Fediverse client development from Fediverse server development.

And more.

@silverpill, should I use the #Ukrainian interface option in #Mitra to mark #ActivityPub posts with this language (instead of #English), or is the interface option not related? I just can't find this in the message form.

In #Tuba app, I can simply select the content language, but I'm not sure about the default web UI behavior.

Happy to read about Roomy project that is open source alternative to discord that supports Activity Pub.

Hello Fedi, any ideas why my account on Vernissage can be found from other platforms like Mastodon or Pixelfed, but does not show any posts?
Other accounts show up with with their existing posts.

Can you point me to something in the settings, @mczachurski?

What did I miss? https://vernissage.photos/@linkshaender

#Vernissage #ActivityPub

A chat platform, alternative to #Discord, uses #ATProto & planned to use #ActivityPub, so that you can log in with your #Mastodon ID . Might eventually be useful for a #WatchParty

Oh I didn't realize the entire vidzy github project was nuked https://github.com/vidzy-social/vidzy

There's a couple of archive snapshots of it though https://web.archive.org/web/20241104180545/https://github.com/vidzy-social/vidzy so at least somewhat preserved

"Letztlich bleibt das #Fediverse eine der spannendsten Entwicklungen des modernen Webs. Es erinnert an die frühen Ideale des Internets: offen, föderiert, interoperabel. Und es zeigt, dass Alternativen zu den klassischen Monopolplattformen tatsächlich funktionieren können."

I've been working all day today improving, fixing, and enhancing the comments system in Incise.

- Comments are now correctly listed for #ActivityPub fetches
- Comments are now likable from the web UI as well as through #ActivityPub
- Comment replies are now #federated as well
- Comments by remote actors (eg. Mastodon users) liked by Incise users are now #federated

An example of the last point, this comment by @Viditb on @dezinezync's post: https://mastodon.social/@Viditb/115960081954678201/favourites

@res260 Do you follow the development of #ActivityPub for #WordPress? I see huge potential there. More than 40 % of all websites run on WordPress and they could become part of the Fediverse in a click.

I love #activitypub but seeing how slow its development is compared to #atproto makes it hard to be excited about it. This goes for both protocol development and ecosystem development.

ATproto has many cool projects popping up every month, the vision is clear and platforms integrate with each other.

I don't see this excitement and work on the ActivityPub side :(

Warum unsere digitale Zukunft nicht Mark Zuckerberg oder Elon Musk gehören darf.

Wir stecken in den „Walled Gardens“ von Meta & X fest. Aber es gibt einen Ausweg: Das Fediverse (Mastodon, PeerTube, Pixelfed).

Es ist weit mehr als eine Nische – es ist Europas wichtigste Chance, die digitale Souveränität zurückzugewinnen:
🔒 Datenschutz: Kein Überwachungskapitalismus.
💻 Unabhängigkeit: Server stehen in Europa, Open Source-Software.
🤝 Kontrolle: Chronologische Feeds, keine manipulativen Algorithmen.

Die EU und Bundesbehörden machen es vor. Jetzt bist du dran!

@zotheca oh ja, unbedingt!! Das hätte ich vor zwei Tagen gebraucht! 😅 Ich find es mangelt noch ein bisschen an gut verständlichen Erklärungen zu #activityPub (incl was es mit den relays auf sich hat) oder ich hab sie in der Eile noch nicht gefunden. Daher: Danke!

PS: vllt kannst du in deinem Post noch ergänzen worum es grob geht ;)

#fediverse

The Quiet app provides high-level technical details of how their app works:

https://github.com/TryQuiet/quiet/#technical-overview

This is actually very similar to one way I imagined a more server-less peer-based usage of ActivitiyPub working.

@Castopod

would it be possible for podcasts to be built on #ActivityPub in addition to RSS, and for podcatchers to process it? then each episode would be its own AP item and we could boost them directly, not just link to them. I feel like that would open up a lot of other possibilities too. #podcasting2

Does anyone have any experience with both #NodeBB 's and #Discourse 's #ActivityPub / #Fediverse integrations? I am wondering what each can and cannot do. I am familiar with NodeBB's federation but not with Discourse's one. It would be great if there was a comparison chart, but I haven't managed to find anything like that. Thanks!

Interesting introduction to the differences between the protocols #ActivityPub (#Mastodon/#Fediverse) and #ATProto (#Bluesky).

Because my Mastodon feed still shows me content in languages other than English and/or Malay, I think I will soon find ways to get a translation API and configure my instance to be able to translate any posts on my feed.

Hi @liaizon @hongminhee,
…and still comes with almost no guarantees to rely on. #ActivityPub

On February 3rd (very soon!) I am hosting another [BERLIN FEDERATED NETWORK EXPLORATION CIRCLE] at @offline. It's a chance to meet and talk with people who are interested in the #fediverse & networking & exploration & circ---you get the idea.

We have the pleasure of having @hongminhee who will give a presentation about @fedify "an opinionated #ActivityPub framework for TypeScript that handles the protocol plumbing"

It is an open free event and everyone is welcome!

Alt...

BERLIN FEDERATED NETWORK EXPLORATION CIRCLE BEFENEC? BEFENEEXCI? we have 洪 民憙 (Hong Minhee) all the way here from Korea with a presentation about Fedify, a fediverse library they have been building that is now powering the federation of things like Ghost and Hackers' Pub come join us offline at offline Lichtenrader Str. 49 Berlin

Edit: Done! https://madeincanada.social/#servers

Instead of manually adding servers to https://MadeInCanada.social, I'll leverage my FediDB.com service with a new API 🔥

#ActivityPub #NodeInfo #Fediverse #MadeInCanada

Alt...

MadeInCanada FediDB API

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.

https://w3id.org/security/v1

(This particular namespace is an HTTPS URL.)

...

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

...

#ActivityPub #Cryptography #Fedidev #Fedidevs #Fediverse #JSONLD

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.

...

#ActivityPub #Cryptography #Fedidev #Fedidevs #Fediverse #JSONLD

3/

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

...

Although https://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?)

How mucg Fediverse software could handle public-keys changing over time?

Etc?

#ActivityPub #Cryptography #Fedidev #Fedidevs #Fediverse #JSONLD

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.

I've submitted a Pull Request to update MacPorts' snac to 2.89 here:

https://github.com/macports/macports-ports/pull/30876

Two of three GitHub Continuous Integration checks are running with a third queued.

Hopefully they'll complete without issues?

If so, it's up to someone else with commit access to merge it!

The most popular fediverse platforms are not American.

That's awesome. Together we're proving that a world of thriving alternatives exist beyond the USA.

We need to embrace that.

So I started https://MadeInCanada.social for my fellow Canadians.

Let's show the world how magical #ActivityPub is 🚀

Hallo Liebes #fediverse,

Ich habe eine Frage bzgl #blogging:
Welche Plug-Ins und Software könnt ihr empfehlen, um Blogeinträge direkt und automatisch auf Kurznachrichtendiensten einspeisen zu können?
Frei verfügbare und Kaufvarianten willkommen!
Es geht leider auch um Insta, X, aber auch telegram und natürlich das fediverse. (Da ist das dann #activityPub?)

Danke schon mal! 🙏

#fedihelp #followerpower

Hey, just wondering, does your #ActivityPub / #Fediverse / Mastodon & friends client display rich HTML / #Markdown posts or do you see plain text (with emoji and attachements)?

If you don’t know but don’t see an italic sentence here, then the answer is no ;-)

Boost ok.

Open social media has a new fan: U.S. Rep. Ro Khanna. The congressman for California's 17th Congressional District appeared on Kara Swisher's "On" podcast last week and talked about Bluesky, @surf, and the importance of being able to construct your own social graph, take your followers where you go, and opt out of algorithms. Here's the full episode:

O que menos importa é a nacionalidade de quem desenvolve um sistema e sim se ele está de acordo com nossos valores que, insisto, passam pela nossa autonomia, que só é possível garantir com software livre.

So one tricky aspect I had to solve with Loops is how we use a hashid of the snowflake id for videos, comments and replies in public links, but also deference them to their full ActivityPub permalink.

I built a `matchUrlTemplate` helper that uses regexes to match our url schemas in a way that supports `/v/abcdefg1-` and `/ap/users/1/video/1234567890` links.

It works great, and I will be bringing this to Pixelfed to improve federation support ✨

https://github.com/joinloops/loops-server/blob/main/app/Federation/Handlers/LikeHandler.php#L150-L175

#LoopsDev #ActivityPub

#Loops has entered #beta with #ActivityPub support, allowing users to connect with creators across the #fediverse. This means users can follow and interact with creators on platforms like #Mastodon and #Pixelfed, and vice versa. Loops has implemented several technical features to ensure smooth federation, including a shared inbox, HTTP signatures, and smart content representation. https://blog.joinloops.org/loops-joins-the-fediverse/?Fedizen.EU #Fedizen #Fediverse #ActivityPub #News

Hashtag following also allow URLs to RSS feeds of ActivityPub objects (like e.g. https://mastodon.social/tags/ThankYouTuesday).

Users can now configure a webhook to receive an HTTP POST for every notification. This can be useful for implementing bots that react to activities, like autorepliers, chatbots or interactive textual games (see snac(1) for more information).

The number of pending follow confirmations is shown next to the "people" link.

Faster performance metrics (contributed by dandelions).

Improved lowercasing in hashtags (contributed by postscriptum).

A search-by-url tweak for implementations that return 200 for invalid webfinger queries (e.g. piefed).

Mastodon API: added follow confirmation endpoints, fixed collisions in attachment file names.

Fixed potential crashes in attachment uploads.

Notifications are now shown in a more compact way (i.e. all reactions are shown just above your post, instead of repeating the post ad nauseam for every reaction).

New command-line option unmute to, well, no-longer-mute an actor.

The private timeline now includes an approximate mark between new posts and "already seen" ones.

Fixed a spurious 404 error in the instance root URL for some configurations.
