#Lazyweb When I want to spin up my own #Fediverse instance that supports #Markdown when composing a post and that can handle my significant amount of followers with a seamless migration from my current #Mastodon instance, which #ActivityPub Implementation would you use? Ideally it should be a simple rootless container setup that JustWorks™ with podman. Perfection would be a single, self-contained container without the need to spin up several ones for databases or other stuff.

In a few days, the last brick of the relay server will be published for an official release and a tag.
A lot of stress when you are alone, but after a few weeks the work has paid off, it is really stable.
Running your own #ActivityPub server on your phone will be as simple as using any other app. You will not be limited to a lookalike: micro-blogging, media, videos, all you want in a simple tap.

If you are at #DwebCamp and you love the #Fediverse please come see my Introduction to #ActivityPub talk at 5pm today in the #OpenSocialWeb tent! It means a lot.

SZ: "Heute wird die sogenannte Open Social Web Alliance #OSWA in Berlin ihre Formierung verkünden. Das Bündnis will nach eigenen Angaben 'das Momentum rund um gemeinwohlorientierte, offene soziale Netzwerke als Gegenmodell zu Big-Tech-Plattformen wie Facebook, Tiktok oder Youtube weiter befeuern'."

Alt...

Boris Christine and Daniel

Goodmorning fedi, I just woke up in a windy tent in the middle of a field and sleepily scrolled thru all the opening talks at #DwebCamp to figure out what my first stop needs to be: def have to catch @cwebber, @dholms.at and @boris discuss the trade offs, design decisions and points of convergence between #ActivityPub and #ATProto

Alt...

Christine Lemmer Webber is lead author and co-editor of the W3C ActivityPub specification. Daniel Holmgren is Head of Protocol at Bluesky, working on the AT Protocol specification at the IETF. Join us for a discussion on decentralization trade-offs and other design decisions in the two protocols, and what that means for different architectures, structures, and even future points of convergence.

Are you into 3D printing, self-hosting and the Fediverse?

If so you might want to look into Manyfold, a FOSS Fediverse platform which lets you upload and share 3D print models:

🌱 https://manyfold.app

You can follow the official accounts at:

🌱 @manyfold@3dp.chat (main)
🌱 @manyfold@makertube.net (videos)

You can host your own Manyfold server using the instructions at https://manyfold.app/get-started/installation (be warned though, installation does require a bit of tech skill).

What project you think #fediverse is missing the most currently? 🤔

#needhelp #askfedi #activitypub #needboost

Habe gestern zwei Bluesky Accounts nach Eurosky.social umgezogen - ein paar Klicks, fertig. Wenn man sieht wie einfach so etwas gehen kann, dann kann man #Mastodon und #Activitypub an die Wand klatschen. Ich frage mich echt, wie man sich einen solchen Schwachsinn für einen Account Umzug innerhalb von Mastodon ausdenken kann. Nicht praktikabel, nur handhabbar für Nerds. Ein System, dass sich Frickler ausgedacht haben ohne den Anwender berücksichtigt zu haben.

I just discovered the Fediverse (English) Wikipedia page has a huge section on AT Protocol and I question why. It seems like excessive promotion of Bluesky and its protocol that is not compatible with ActivityPub, both technically and in spirit. Illustrating bridging isn't the same as compatibility. Might as well add sections for other random network protocols like XMPP (Jabber).

#ActivityPub #Fediverse #wikipedia

reflecting a lot on #fediverse lately. instance hopping is such an event and sometimes disruptive. ive spent a lot of time running #chatmail relays and until recently contributing to upstream. we can relay hop and its almost silent. your cryptographic identity is owned by you, not the relay operator. giving you a feeling or being nomadic. servers go down, operators retire or fade out. but you keep your identity.

this works great for #deltachat and enjoy the flexibility. but #activitypub doesn't have an agreed upon implementation. @silverpill is doing great work with his research and #mitra ecosystem. my hopes are eventually we'll see this on fedi across the ecosystems.

Great post, I suggest to anyone interested in the ActivityPub spec and technical architecture to read it. I had no idea the tool echosystem had this many problems, and Fedify handles a lot of them for you!

@res260

"Post pending" on your quote post.

I think perhaps I know the article you want to refer to, and I'm able to quote it. But this makes me wonder about the quote post functionality in general. If you don't get the approval, then your post is meaningless to others, as there is no context.

Before quote posting existed you could share a link to someone's public toot, and clicking it would open it in a new browser tab. Perhaps the consent mechanism is okay as-is, dunno, but it is a bit weird that you can freely share an URL to someone's public blog post, but not to someone's public fediverse post because it is seen by default as an attempt to inline the post with yours.

RE: https://hackers.pub/@fedify/2026/why-activitypub-is-hard

This is a really great, technical overview of how the fediverse works behind the scenes. And really makes you appreciate that it works at all.

Massive props to @hongminhee for this write-up and all their work, and those of others that make fediverse possible.

#fediverse #activitypub

Saker jag funderade över innan jag somnade igår; det här med kopplingen mellan #wordpress och #mastodon (eller snarare #fediverse) via #activitypub. Jag har fattat att wp-installationen blir som en egen instans i systemet. Att det som skrivs på bloggen kan både läsas och kommenteras både där och här, och även kommentarerna syns både här och där. Är det rätt så långt?

Men hur visas bloggposterna, som ju i regel är längre än maxantal tecken här? Kan någon peka på ett exempel?

I'm requesting final comments on FEP-7628: Move actor

When X, Meta and TikTok relaxed their rules on hate speech, racism and transphobia, they didn't undermine the open social web.

They proved why this needs to exist.

Safety and mental health come first here. They're the foundation everything else stands on.

Not optional. Not negotiable. The vulnerable come first, always.

I have a roadmap to improve this, and I'll soon be asking for your feedback to make these spaces safer for the people who need them most.

How does ActivityPub really work?

Listen to this presentation by #ActivityPub co-author @evanprodromou given at the last FediForum:

I submitted a Pull Request to update MacPorts' snac to 2.93 here:

https://github.com/macports/macports-ports/pull/33311

GitHub Continuous Integration checks passed OK!

It's up to someone else with commit access to merge it.

Thanks to violette, hanchan, inz, lainsoykaf, nullenvk, e0w0e, dragondaddy, daltux, zen and anyone else I may have missed for also contributing to the improvements in this release!

I'm thinking a federated wiki type service with a trust metric that allows more trusted users to moderate/curate edits.

We could expand this beyond related hashtags.

Pixelfed has a related hashtags feature, and I'm thinking maybe we should create a global corpus to help curate them.

What do you think?

It's much cleaner and informative, though it does need the final schedule and speakers.

I also added some logic to hide sections after certain dates 😎

#snac2 #fediverse #frugalfediverse

Added a new admirations entry point to the web UI, containing a timeline of liked, boosted and reacted posts. Please take note that, after installing the new version, it will start empty, and be filled with subsequent reactions (contributed by violette).

It's now possible to disable showing posts in a given set of languages.

Nested quoted posts are limited up to 3 levels.

New configuration knob: by setting keep_replies_posts to true in server.json, remote posts that a local user has replied to are retained in the public timeline, preventing them from being purged (contributed by hanchan).

New configuration knob: by setting keep_replied_me to true in server.json, remote replies to local posts are retained in the public timeline, preventing them from being purged (contributed by hanchan).

Ensure actors' public key PEM never includes anything after the end marker.

Fixed some memory leaks (contributed by inz).

Several additional keyId checks (many thanks to lainsoykaf for bringing this to my attention).

Fixed crash in the JSON parser (many thanks to nullenvk for bringing this to my attention).

Mastodon API: fixed lost custom emojis after edition (contributed by e0w0e).

Updated French, Brazilian Portuguese, German, Spanish translations (contributed by dragondaddy, daltux, zen).

Two things you can see here... It's pretty hot! That's why I stayed home and implemented a missing feature into snac. That's what you can also see - it finally sends push notifications to devices! In this case, we can see notifications coming from #MastoBlaster App for iPhone.

What we can also see, it's still a bit faulty and not the expected content, but a first success here at least ;) I'll make some further adjustments when there's time and get in touch with @grunfink@comam.es to check if we can get this upstream. Thanks to @stefano@bsd.cafe for testing with me :)

snac2 sending push notifications to a user via MastoBlaster App on iPhone

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.
