DrFed is our sister project, built alongside #Fedify to tackle the debugging side of #ActivityPub development. It just received @nlnet@social.nlnet.nl funding and now has its own account here: @drfed@hackers.pub. #DrFed #fedidev #fediverse #NLnet RE: https://hackers.pub/@drfed/019ed3c9-7e8c-782f-a512-5fbc75a4610b

Some of you have already heard of us as #Fedify Studio. We now have a proper name: DrFed, short for “Doctor Fed.” We've also just received funding from @nlnet@social.nlnet.nl, through the NGI0 Commons Fund. #DrFed is a web app for debugging #ActivityPub interoperability failures. When two implementations don't federate, the slow part is usually figuring out where the exchange broke: signing, JSON-LD processing, WebFinger, or something less obvious. DrFed's first job is to show where it failed. We're the team behind @fedify@hollo.social: @2chanhaeng@hackers.pub, @gaebalgom@hackers.pub, @hongminhee@hollo.social, and @z9mb1@hackers.pub. We'll post updates when there's something to try. #fedidev #fediverse

This is Haru and Tanos. Haru is the black cat. We adopted him from a shelter at two years old, after he lived there his whole life. Tanos is a Malinois. We took him in when his owner could not keep him anymore. Life can change fast, animals are often the first to lose their home. This is why I made #PawFed, a shared map for animal welfare. Not many people use it yet, but it is worth sharing. It relies fully on #ActivityPub and uses #OSM. https://pawfed.org/how-it-works

RE: https://toot.fedilab.app/@apps/115572783993063223 This post is about 7 months old, and #HolosSocial went far beyond it since. It now has #E2EE DMs with the Signal protocol, and real identity portability. You can use a custom domain so your identity rests on your own name and keys, and keep your media on your own cloud. Leaving a relay is no longer a migration, you just point your domain elsewhere and keep going. This remains optional, you have time to discover the app and enable things later that will give you full independence on #ActivityPub.

Quoting

Fedilab Apps @apps@toot.fedilab.app

We're building something for the Fediverse. #Holos

ActivityPub running on your phone. Your own server, your data stored locally. A relay handles your stable identity when you're offline.

One account, all formats. Short text, long articles, photos, videos. The UI adapts to your mood. Switch between text mode, photo grid, video feed, article editor based on what you feel like sharing.

Same network, same followers.

Early stages, but the foundation is solid. We wanted to share the progress.

Somebody went and built a chatroom powered directly by #ActivityPub, called "Harmony". Roughly the opposite of Movim, Harmony aims to replace Discord and even includes end-to-end encryption (although I wonder if it'll be compatible with the implementation by Bonfire and Emissary). mony.lol/

The full changelog: Fixed Prevent runaway recursion when handling filtered posts.Ensure profile header and header_static images are always present.Render the inline replies collection for local objects.Exclude blocked actors from object statistics and notifications. Changed Return 410 Gone instead of 404 Not Found for missing actors. Removed Tag counts on public pages. This release fixes a hard-to-exploit but potentially server-crashing bug. If you're running v3.3.9 or v3.4.0, you should upgrade. #ktistec #crystallang #activitypub #fediverse

Feature Highlight for v4.12.0 — Activity Intents

A new feature silently dropped in v4.12.0. NodeBB now supports Activity Intents! <h3>Huh? What's an Activity Intent?</h3> It is <a href="https://w3id.org/fep/3b86" rel="nofollow ugc">a proposal</a> by <a href="https://mastodon.social/@benpate">@<bdi>benpate@mastodon.social</bdi></a> that aims to "extend the capabilities of an ActivityPub server beyond a user's outbox, and enable direct interactions with content on the wider social web." In other words, it allows you to more seamlessly use your fediverse account on other sites without having to register a new account just to contribute. In even simpler words, it means you can go to other forums and interact with content without needing to register a new account. It directly tackles one of the fediverse "hard problems" I talked about last year — account fragmentation. You won't need additional accounts just to use other sites, your identity stays whole :sunglasses: Let's learn more about how that works![...] Hover or focus to reveal Sensitive

A new feature silently dropped in v4.12.0. NodeBB now supports Activity Intents! Huh? What's an Activity Intent? It is a proposal by @benpate@mastodon.social that aims to "extend the capabilities of an ActivityPub server beyond a user's outbox, and enable direct interactions with content on the wider social web." In other words, it allows you to more seamlessly use your fediverse account on other sites without having to register a new account just to contribute. In even simpler words, it means you can go to other forums and interact with content without needing to register a new account. It directly tackles one of the fediverse "hard problems" I talked about last year — account fragmentation. You won't need additional accounts just to use other sites, your identity stays whole

Let's learn more about how that works![...] Account Fragmentation in a Nutshell Right now, when you browse to a different site, you usually have to create a new account to interact with it. For example, if you check out someone's Pixelfed profile, you're not able to comment or like their pictures without an account there. This has always been how the internet worked, and before the advent of single sign-on, which lets you log in with a different account (but still creates a new account on that site), that was just how it was. Essentially, there was no way to interact with content using your main identity. The workarounds were numerous... copying URLs, searching for the account on your instance, etc. All of which were fairly friction-heavy, so the next best thing was just to create a local account and fragment your identity. Activity Intents intends (ha!) to address this by allowing servers to advertise support for different types of social actions. How It Works You browse to another site and want to carry out an action, such as liking the post, or writing a reply. That site asks you to enter an Open Social Web handle (or log in, if you have a local account), and you enter it. It then queries your server to see what Intents it supports (e.g. "Like", "Create") If there's a match, it sends you back to your server, where you can complete the action. That's about it! There are additional details about designing the actual flow, and how to "remember" each visitor's social web handle, but the basics are as listed above. What it looks like in NodeBB We've integrated support for four intents: Like/Dislike → These map to upvote and downvote respectively Create → These would be topic creations and replies Follow → self-explanatory Object → Load an ActivityPub resource in NodeBB We integrated two-way support which means that if you land on a NodeBB and your fediverse account supports Activity Intents, then you can simply hit like, reply, or follow from NodeBB, and be sent back to your home server, all without the hassle of copying and pasting links into a search bar. Integrating Activity Intents was a high-impact way to tackle the problem of account fragmentation. Users of NodeBB (whose forums have updated to v4.12.0) should not have to feel pressure to create local accounts elsewhere if the site they end up on supports Activity Intents as well.

RE: https://mastodon.social/@HolosSocial/116664862916238317 Today the #HolosSocial project takes a step forward by letting one account run on several devices. It may sound minor, but each device runs its own #ActivityPub server, which made it a real challenge: avoiding duplicate actions sent to other instances and keeping everything in sync. All of this stays transparent for the user: adding a device is as simple as scanning a QR code, and the whole transfer is end to end encrypted between the two devices, so the relay never sees it in clear.

This is a recent talk that captures the main goal of why we are developing Commonshub. The world needs and wants a healthy alternative to toxic centralized social media and it exists but not enough people know about it. That will change if more organizations and or individual creators setup up their own communities and invite people to join. Exactly what Commonshub is designed for... https://watch.2mr.social/w/k3ngQ8Xr3ANRXe6D8YGP4Y https://thecommonshub.com #mastodon #fediverse #activitypub #opensocialweb

Meet #Starling, a lightweight #ActivityPub server for the #Fediverse, built with PHP and SQLite. Run your own decentralized social platform on shared hosting or a tiny VPS WITHOUT Redis, PostgreSQL, or complex infrastructure. What it makes so special to me? It looks awesome, comes with a great admin web interface and does not require a VPS instance where it can also be operated on a cheap shared hosting systems. By the given requirements, it also easily runs on a #RaspberryPI and all kind of systems, including #FreeBSD, #OpenBSD, #Illumos and more! This all makes it perfect to everyone and even beginners to run their own instance. With relay support (e.g., fedi-relay.gyptazy.com) it even can consume and post content over non-directly connected instances in the #fediworld! Kudos to the author of Starling: @df@s.dfaria.eu More information: GitHub project: https://github.com/dfaria-eu/Starling My blog post: https://gyptazy.com/blog/starling-simple-fediverse-server/ #fedi #fediwall #opensource #decentralized #social #socialmedia #alternatives #mastodon

Most people know about messages, photos and videos on the #Fediverse. But the #ActivityPub protocol actually defines several object types, each one distinct and more or less compatible across apps:

Note: short post (Mastodon)
Article / Page: long text or shared link (WriteFreely, Lemmy)
Image (Pixelfed)
Video (PeerTube)
Audio (Funkwhale)
Event with date and place (Mobilizon)
