#ActivityPub trick question. If a C2S client actor identified by “http://bar.example/actor” posts {“id”: “https://foo.example/something”} to its *outbox* server endpoint, is that valid? Why or why not? If the answer is “it depends”, it depends on what?

#Fedify 1.6 is approaching with three major enhancements: RFC 9421 HTTP Message Signatures support with double-knocking for seamless backward compatibility, a new builder pattern for better code organization in large applications, and native #Cloudflare #Workers support for serverless deployments. These additions strengthen Fedify's standards compliance while expanding deployment flexibility across different environments. Stay tuned for the official release! 🚀
#ActivityPub #fedidev #fediverse #RFC9421 #CloudflareWorkers
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.

Exciting news for the #Hollo project! We're thrilled to announce that Emelia Smith (@thisismissem) has joined as a co-maintainer alongside Hong Minhee (@hongminhee).
Emelia brings extensive experience in the #fediverse ecosystem, having been a long-time contributor to Mastodon and a leading expert in trust & safety tooling for decentralized social networks. She's dedicated years to improving moderation systems and security across #ActivityPub platforms.
Her recent contributions to Hollo have been substantial—implementing the reporting/flagging system and making significant improvements to OAuth and security features. These valuable contributions naturally led to her joining as a co-maintainer.
This collaboration marks an important milestone for Hollo as we continue building better single-user microblogging software for the fediverse. Welcome aboard, Emelia! 🚀
Embarrassed to say I completely missed the publication of this project site for Mastodon’s fedidiscovery project.
It aims to improve searching and discovery of content across instances work in an opt-in, decentralized manner.
Did you know? #Fedify provides #documentation optimized for LLMs through the llms.txt standard.
Available endpoints:
https://fedify.dev/llms.txt — Core documentation overview
https://fedify.dev/llms-full.txt — Complete documentation dump
Useful for training #AI assistants on #ActivityPub/#fediverse development, building documentation chatbots, or #LLM-powered dev tools.
Hey #Fediverse, do you love #TV? I've launched a new app to track your tv in a single user app with #activitypub support!

The Work Continues: What’s Next
Details will follow soon — but the work on events in the #Fediverse is far from complete. Key upcoming milestones include:
Improvements and new features for the Event Bridge for ActivityPub plugin for WordPress
Continued development to maintain, fix issues, enhance, and expand functionality.
Work on Fediverse Enhancement Proposals (FEPs)
Ensuring a robust final status of FEP-8a8e and focus on recurring and irregularly scheduled events.
Support for event interoperability in other Fediverse applications
Contribute to other Fediverse applications and help them to explore and improve support for Event objects. For example, @linos has outlined a potential roadmap for Mastodon.
Contribution to GatherPress
Active involvement in the GatherPress project — a modern and truly FLOSS community oriented WordPress event plugin — to ensure full ActivityPub compatibility, including RSVP support and advanced federation features.
Community engagement and outreach
Participation in conferences, public talks, and direct conversations to foster knowledge exchange, gather feedback, and grow the ecosystem around federated events.
Additional updates and technical details will be shared soon. Input, testing, and collaboration from interested parties are always welcome. Or if you know any conferences we should attend, let us know.
#ActivityPub #Events #Fediverse #FEP #GatherPress #WordPress
Taking a look at the Wordpress ActivityPub Roadmap, at the very end I see this:
> Client-to-Server API (exploration)
> At this stage, we’re exploring and evaluating this based on community interest and potential use cases.
Client to Server API for ActivityPub is not widely utilized (or at all?) so this would be of great benefit to all fediverse platforms.
SHOW YOUR COMMUNITY INTEREST!!! @activitypub.blog

Mastodon API: fixed a regression (introduced in previous version in the "boosts disappear in Tusky" fix) that interrupted timelines.

Happy to be finding so many fediverse merchandise stores lately - I was sure I had them all when I setup the list originally. Glad to be proven wrong.
Here's an instance specific one - get the vmst.io logo on a t-shirt! The title of the shirt is "Toots In / Toots Out". 🎺

[a very well-written article with a favorable yet realistic angle on the #Fediverse]
"At the heart of these alternative apps lies the Fediverse platform — a portmanteau of "federated" and "universe" that represents a radical reimagining of how social media can work. Unlike traditional platforms where users are locked into isolated ecosystems, the Fediverse operates as an interconnected network of independent servers that communicate with each other through a standard protocol called #ActivityPub."

#NoAds, #NoManipulation 🚫 Big Tech shapes opinions through targeted ads and polarizing content: #Opensource #socialmedia empowers #communities with transparent #moderation.
#Better #MentalHealth 🧠 Research shows that algorithm-driven feeds fuel anxiety and addiction: #ActivityPub platforms, like #Mastodon, avoid manipulative engagement tactics. (1/2)
I am looking for experts/#developers who are familiar with #ActivityPub and who might be willing to chat with me.
I have started talking with parts of my network (mainly in D and NL), about how we could make the #Fediverse more interesting for content providers and main stream media. This also means attracting ordinary users to join and to find fair and simple ways to support content providers (without #paywalls).
I have some ideas, but now need more expertise and a deeper look under the hood.
I decided since I don't understand how all of this works, I will just simply ask Jerry personally about all of this data and technical details, so that people will no longer be confused about all of this.
Includes an exclusive interview with Jerry.
✅ Só li ese post hoje e ele não está errado.
✅ Esse negócio de entrar num perfil e não ver os posts é muito comum aqui.
✅ Esse amadorismo dos administradores de instâncias acontece muito aqui no Brasil também.
✅ Falta de caixa de entrada para mensagens é mesmo um problema.
✅ A migração é realmente limitada. Também acho que deveria trazer o conteúdo.
___________________
⭕ Entendo a decepção, mas não acho que o administrador da instância esteja errado em limitar os bots. Creio que ele deveria ter escolhido uma instância própria para isso.
⭕ E minha experiência no Bluesky foi tão ruim que já exclui minha conta (agora só tenho um clone do Mastodon lá).

This week's #fediverse news:
- @activitypub.blog talks about how they plan to make WordPress sites a full member of the fediverse, with replies, follows, and your own feed
- @fediforum videos now available, with some thoughts on the ones that stood out to me
- server admins can now opt-in to @fed.brid.gy on a per-server basis
- @swf releases draft for E2EE messaging over #activitypub with MLS
Listen! #Knowledge coming from #museums:
"#ActivityPub is plumbing. It is plumbing built on top of the web, which coordinates the ability for independently operated services, for example a collection of federated social media services, to exchange messages with each other in a decentralized manner.
So #SFOMuseum has built its own ActivityPub server for publishing #socialmedia style messages.
In doing so, it means that we can(& have)created social media accounts for 60,000 objects in our collection including this roll of #HelloKitty toilet paper from #EvaAirlines."

👋 Hello #fediverse ! Abelio is a new work-in-progress federated media publishing platform aiming to become a #tumblr and #photoblog alternative for #artists and any sort of #creators (#writers included).
I don't have any demo to show you yet but i needed a way to announce and ask for things - so if you care, please follow! Here is how admin panel looks so far.
Spreading the info and participating in discussion highly appreciated! ❤️
Xab hai rotto con tutti questi account
Lo so, lo so, perdonatemi!
Per ora qui sto giusto sperimentando, l'account principale al momento resta @Xabacadabra e qui sto prendendo le misure per un eventuale futuro:
Intanto, mi sconvolge poter scrivere quanto voglio senza dover spezzare in mille post un thread (anche se a parte questo post mi terrò sempre sui soliti 500 caratteri con un post nel blog per cose più lunghe)
Poi trovo bello mantenere il discorso Mastodon senza usare Mastodon (software che da tempo mi pare problematico per l'accentramento che occupa nel fediverso e la vecchia questione threads )
L'altro aspetto interessante è che sto scoprendo di più riguardo il protocollo #activityPub che tiene in piedi tutta la baracca
Hello World!
I just spoke with a #US #Senator office about the #fediverse . They're asking for more information to help spread around #Capital #Hill in small bite sized easy to understand pieces. I'm obviously going to give them @elena beautiful #movie on the #fedi (with some light editing which she's agreed to).
I'll of course show them https://fediverse.info/ and https://fedi.tips/ which are great websites. I figured I'd give them examples of amazing #AP projects such as #mastodon , #pixelfed , #peertube , #bandwagon , and #bonfire ; even things like @admin .
I'd love to know from folks any EASY to understand projects that best encompass the Fediverse and explanations of it.
What are some projects you'd hand to your friends and family that would explain and display to them what we are?
I'll say this isn't going to happen over night. There's lot of questions around regulations, trust & safety, etc. But I feel it's pertinent to at least get the conversation going, especially considering the current state of disdain for big social media and the impending legislation around these things.
I'll finally state if there's anyone in this list that does NOT want to be involved with this, that's totally fine and I understand and I can exclude you from the materials I give to them.
