I would even host it at home, but it seems like huge parts of the Fediverse are IPv4-only, and #ActivityPub behind Dual-Stack Lite doesn't sound like fun.

I haven't published the code for the ActivityPub project yet because I haven't written the code that lets users post things. For the moment, it just implements webfinger and `Person` payloads.

Still quite a bit to do to get it to a baseline of talking to other AP implementations like Mastodon and Ktistec, but I'll post more here when I get that working.

#ActivityPub

Hubzilla Beginner's Workshop Today, Feb 11 (German)

Great to see these type of events popping up!.

#Fediverse #ActivityPub

With https://discover.holos.social we may have highlighted that many Fediverse users don't pay attention to their default settings. We built a fully respectful search engine that only relies on #ActivityPub, with instant deletion, updates, and indexing only consenting users. We will likely shut down the service, but the source code will remain available as we believe the approach is ethical. That same indexable setting already lets Google index your posts and keep them cached long after deletion.

Just sent my first signed request to #Mastodon that was accepted. This took much more time than it should have, but the next steps should become much simpler. #rust #activitypub

New blog post: I added Fediverse-based comments to my Pelican blog.

No Disqus, no database, just the Mastodon API and a bit of JavaScript.

Replies to this post will show up as comments on the article.

Inspired by the blog of @jwildeboer - I ported it to Pelican's Jinja2 templates.

#fediverse #activitypub

@jrollans I don't know how close #Funkwhale gets to what you seek, but it is an interesting #ActivityPub application to check out, if you didn't know it already..

https://www.funkwhale.audio

I started using a service called Concert Archives (it is what it sounds like) and I really like it! It’s helped me remember live shows that I had forgotten I even went to and artists I didn’t even recall seeing until looking at the archive entries.

I wish it was federated with #ActivityPub, something like that on the fediverse would be very cool.

Here’s my profile (still working on adding concerts, lots more to go…) https://www.concertarchives.org/jonathan-rollans

#Music #Live #Concert

I gotta say Google, the degradation of your Search product is now almost complete.

I was looking for documents that I am fairly sure exist; at the intersection of three specific technical disciplines.

Namely
#activitypub #duckdb #python

And basically just want to throw my archives into duckdb and have them in whatever schema the JSON-LD of a mastodon archive carries, so I could do a bit of analytics on my past self.

And for the first time you didn't produce a useful top level result that I could use to find what I was looking for.

You've gotten dumber Google and it shows.

Has anyone figured out how to use ActivityPub to make something IRC or Discord shaped?

#activitypub #irc

Corporate platforms control speech via algorithms & bans. The alternative? ActivityPub, the open protocol powering the Fediverse (e.g., Mastodon). It creates a network of independent servers that interconnect—like email. You choose your community, own your data, and see a chronological feed. A return to user sovereignty online.
#ActivityPub #Fediverse #freedom

Reminder to anyone managing a #ActivityPub project that matrix has been adopted as the chat solution by bookwyrm, write.as, friendica, plume, pleroma, fedilab, funkwhale, mitra, forgefed, mobilizon, phanpy, tokodon, moshidon, lemmy, gotosocial, bonfire, voyager, tusky, lemmy, loops, piefed, pixelfed, manyfold, owncast and others. You don't need to start from scratch if you leave discord : join us on matrix!

@Gargron

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

https://itsfoss.com/roomy-discord-alternative/

#roomy #opensource #activitypub

And you should also note how (nly a fraction of #ActivityPub boosts that traverse the #fediverse get actually notified to and/or collected by the original server due to the distributed and eterogeneous nature of the network.

In some cases, following the boosts over the network (eg opening with a browser the boosted post on the boosting account) I've noticed a factor of 3-5 between the number of boosts my server recorded and the actual boosts occurred.

For example take this post that got notified for 120 boosts

Following some of them I see that it got at least:

• 119 boosts on https://mastodon.social/@giacomo@snac.tesio.it/116019294292839723
• 111 boosts on https://mastodon.online/@giacomo@snac.tesio.it/116019294368731338
• 106 boosts on https://mstdn.social/@giacomo@snac.tesio.it/116019294398725122
• 102 boosts on https://mas.to/@giacomo@snac.tesio.it/116019294338400575
• 88 boosts on https://infosec.exchange/@giacomo@snac.tesio.it/116019294113374994
• 78 boosts on https://universeodon.com/@giacomo@snac.tesio.it/116019294115426342
• 71 boosts on https://techhub.social/@giacomo@snac.tesio.it/116019294169907674
• 45 boosts on https://piaille.fr/@giacomo@snac.tesio.it/116019294126051523
• 43 boosts on https://todon.nl/@giacomo@snac.tesio.it/116019294160074426
• 36 boosts on https://scicomm.xyz/@giacomo@snac.tesio.it/116019294443167694
• 30 boosts on https://toot.io/@giacomo@snac.tesio.it/116019294130168032
• 28 boosts on https://hessen.social/@giacomo@snac.tesio.it/116019294160776737
• 26 boosts on https://tilde.zone/@giacomo@snac.tesio.it/116019294154664854
• 21 boosts on https://sueden.social/@giacomo@snac.tesio.it/116019294115914076
• 19 boosts on https://masto.es/@giacomo@snac.tesio.it/116019294300865512
• 9 boosts on https://twiukraine.com/@giacomo@snac.tesio.it/116019294173853433
• 7 boosts on https://bewegung.social/@giacomo@snac.tesio.it/116019294170759818
• 7 boosts on https://poliversity.it/@giacomo@snac.tesio.it/116019294286275262
• 4 boosts on https://social.noleron.com/@giacomo@snac.tesio.it/116019294109759945

So ultimately, the #fediverse reach is much bigger than the one centalized platforms like #bluesky or the various #BigTech playgrounds, where some messages in particular are silently censored.

FEP drafting: Am I using “side effects” here the same way as other ActivityPub developers? I've seen the term used a bunch in casual conversation, but my personal understanding of it is kinda fuzzy.

#ActivityPub #FediDev #FEP

Alt...

The "side effects" of an activity are everything caused by the activity other than it being visible in its actor's outbox and getting posted to its audience's inboxes. For example, a like or reply being represented in the affected object's `likes` or `replies` collection is a side effect, as is likes or replies being shown on a web page corresponding to the object.

there is currently a #Piefed Hackathon going on if anyone is interested in partaking. There are groups working on spanish, german, french and japanese translations, and a bunch of other things.

@fajfer has helped #badgefed by deploying it to its first Kubernetes environment, smoothing out the rough edges to make it work properly, and now I’m proudly quoting his badge to test quotes!

Comment if you can see this quote in #mastodon!

#activitypub #fediverse

@hongminhee I'm reading this thread as a relative noob, but what I see again and again: almost no one "properly" implents #ActivityPub largely because #JSONLD is hard but also because the spec itself is unclear. Most people who get stuff done have to go off-spec to actually ship.

This seems a fundamental weakness of the #fediverse - and that disregarding the limitations coming from base architecture. Seems to pose a mid/long-term existential threat.

What can we do to help improve things?

Will Mastodon, the platform that keeps the #Fediverse alive, miss a strategic opportunity to bring official institutions on board at scale?

By watching how #EuroSky is being marketed compared to #Mastodon, it certainly seems that way.

I wish the folks at Mastodon would invest in more professional marketing, similar to what we're seeing from its rival, Bluesky.

There was a major meeting in the EU Parliament focused on this topic, yet there was no announcement or microblog post from Mastodon. Zero engagement.

Compare these two approaches:

It’s really surprising to me that the #fediverse hasn’t agreed on a standardized way to open cross-instance #activitypub objects and instead relies on links that open in the browser. #urischeme

I found this proposal and what’s thinking… https://codeberg.org/fediverse/fep/src/branch/main/fep/07d7/fep-07d7.md Which one would be your favorite?

(If anyone has updates on the progress, feel free to point me in the right direction)

FediMTL, on the fedi at @info is a new 1-day fediverse related conference in Montreal in just a few weeks on February 24 (is it Fedi-conference season or something?)

There's a streaming option, too! And the sessions look good. Check it out, and spread the word.

Updated the ActivityPub Relay page and added a "Relay policy"

We aim to keep the relay safe, respectful, and usable

We will remove any servers known to actively promote homophobia, transphobia, racism, or any other form of bigotry

We expect participating servers to be at minimum well maintained (e.g., reasonable upkeep, responsive administration, and not persistently broken or abusive to federation)

Having some silly fun with @stegodon a new fediverse platform with an SSH TUI interface. The first screenshot is the web profile, the second is the TUI interface.

This is the first command line UI for ActivityPub client I've seen that has an actual backend server platform tied to it.

The web profile for my Stegodon user, Captain Caveman. It looks very terminal-esque.

The SSH UI showing the Home timeline.

It's amazing to me how perfectly integrated Threads is into Mastodon, but the vice versa still isn't true. Posts are kept in a separate category with little to no way to interact.

Did Meta give up on Fedi?

#threads #meta #mastodon #fediverse #activitypub

I know this is going to be a hard lesson for people on the #Fediverse to learn, but here we go:

NOT EVERYONE ON THE FUCKING PLANET KNOWS HOW TO DO THE THINGS WE DO!

While I’ll take #ActivityPub over #Bluesky, #Threads, and #Twitter, some of y’all make it so difficult to just exist in a space without having to “well, actually” every fucking thing!

Understand that not everyone has all the answers (you sure as shit don’t) and treat people with some fucking grace and respect!

Acho muito válido até impulsionar novamente publicações próprias que ainda considere relevantes, quando tiver contato com elas posteriormente.

Por outro lado, pode ser relevante uma opção de desabilitar a visualização de quantas curtidas e quantos impulsionamento uma publicação teve. Bem como sobre receber notificações disso, algo que já é mais comum. Phanpy, por exemplo, creio que tenha ambas possibilidades.

A client to server protocol, or "Social API" This protocol permits a client to act on behalf of a user. For example, this protocol is used by a mobile phone application to interact with a social stream of the user's actor.

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.

Screenshot of the github vidzy repository showing the README which says "this project has been discontinued we suggest using loops.social

#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.
