ChanHaeng Lee (@2chanhaeng@hackers.pub), one of the @fedify@hackers.pub maintainers, is asking the #fediverse which of his two projects he should present in the Social Web devroom at @fosdem@fosstodon.org 2027.
@drfed@hackers.pub is an #ActivityPub debugging tool that he is building with @z9mb1@hackers.pub, @gaebalgom@hackers.pub, and me. fedi.blue (https://fedi.blue) is a library for servers that interoperate over both ActivityPub and the AT Protocol. Both would make good talks, which is why I would rather the audience picked.
The poll closes on 13 November 2026, so vote for the one you would rather sit through. #Fedify has three maintainers now, and all three of us are going to #FOSDEM 2027 and submitting proposals to the devroom. (The CFP is open until 27 November 2026 if you have a talk of your own.)

Hello, Fediverse! I’m trying to decide what topic to present at FOSDEM 2027 – Social Web Devroom. Which of these two would you be more excited to hear about?
DrFed: DrFed is an ActivityPub debugging tool that @hongminhee@hackers.pub, @z9mb1@hackers.pub, @gaebalgom@hackers.pub, and I are building as a team.
fedi.blue: fedi.blue is a library for building servers that interoperate with the ActivityPub and AT protocols.

I wrote an article to clarify some of the terminology in the #ActivityPub specification related to collections, streams and HTTP endpoints.

Working on a FediHood-inspired "Nearby" feature for Catodon. Since FediHood's development has halted, I'm using it as a base, but without being restricted by it. I'm trying to build this not only thinking of Catodon's implementation, but with fedi on my mind, since we don't have a standard for location, and it could be useful for a lot of cases (events, marketplaces - even a federated dating app could use something like this, why not). So once I'm done, I'll propose two FEPs, so that other projects can also build on this.

Interessant @sander@waag.social Ik ben benieuwd naar de gezamenlijke infrastructuurprojecten. Zijn die erop gericht de twee protocollen gemakkelijker gecombineerd te gebruiken? Eén groot open social web?
https://waag.org/nl/article/europeansocial-gelanceerd-berlijn-de-beweging-voor-het-europese-sociale-web/ "De komende tijd richt de vereniging zich op gezamenlijke infrastructuurprojecten en het vergroten van de steun voor open sociale initiatieven in Europa. De eerste jaarlijkse bijeenkomst vindt plaats in juni 2027, tijdens de PublicSpaces-conferentie in Amsterdam. Ook gaan de oprichters aan de slag met een bestuursstructuur die samenwerking tussen alle deelnemers stimuleert en mogelijk maakt." @publicspaces@social.publicspaces.net#ActivityPub #ATProto #Mastodon

#Smithereen 1.1 is out!
In this update:
- Full-text search on walls, in group discussion boards, and in private messages
- Mastodon-like fetching of all comments for remote posts when you open them
- Moderation improvements: better domain blocks, bulk actions on users
- Support for making posts from external share buttons (FEP-3b86)
- As usual, way too many minor improvements and bug fixes

I've been carrying around an idea for a federated code forge for a while. Two things sharpened it recently: Tangled's post on the federated code forge, which builds a forge on the AT Protocol, and a Jujutsu workshop (Korean) by Seongmin Lee (@boltless.me), who works at Tangled, held at @turingappledev@hackers.pub.
My version would build on ForgeFed, the #ActivityPub protocol for code forges (spec), so that repositories, issues and merge requests federate the way posts already do. The idea is early enough that I haven't even come up with a codename. What I want from it, roughly:
Git and Jujutsu (so-called jj) as equal clients. Not Git hosting with Jujutsu support bolted on, but a forge that understands both, so what Jujutsu is actually good at, stacked changes, becomes a first-class unit of review instead of a pile of separate pull requests.No owner layer. Since the point is federation, one instance represents one person or one organization, permissions are managed per server, and a repository lives at forge.example/myrepo instead of forge.example/owner/myrepo.A migration path off GitHub that keeps the history. Importing the code is easy; importing the issues, pull requests and discussions with their original authors attached is the part that matters. I'd keep a placeholder for each GitHub account and let whoever owns that account prove it, after which the instance swaps in their fediverse actor, so attribution carries over. How to express that claim in ActivityPub is the part I haven't figured out. It may need a new FEP.
Where this stands: I haven't read the whole #ForgeFed spec, Fedify doesn't ship the vocabulary yet (fedify-dev/fedify#751), and I have too much else going on to start soon. If you've run a forge or implemented ForgeFed, I'd like to hear whether any of this makes sense.
#codeforge #fediverse #fedidev
So when I added support for Loops to https://columnly.social I had to refactor quite a bit to abstract MastoAPI routes and entities properly.
Not only did that open the door to supporting other software more properly, but also inspired me to look into ATProto support so you could combine all your social web accounts in one beautiful client.
No promises, but I do look forward to implementing this when I have time!

I notice most people name their #Wordpress blog's #ActivityPub handle as @blog ..
With tons of blogs with the same handle prefixes this makes your blog hard to mention, and people have to remember and type the full #fediverse handle before it shows up in the account dropdown dialog of the post editor. Just saying.
I wrote another FEP, this time for C2PA ✨

📢 Account move notification
Almost everything is ready to move my social home to @fabio@manganiello.tech (@fabio@manganiello.tech).
The new account runs on #Yonder.
Yonder is a social platform I’ve been working on for a while, and I’ll soon write about it more in detail.
It’s an #ActivityPub server written in #Rust and fully compatible with Mastodon and Pleroma/Akkoma, plus with other #Indieweb features I like (support for #Webmentions, and #OpenID coming soon).
Plus it implements features (like on-demand remote fetch of statuses/threads context, support for Threadiverse-like actors, OAuth-based account migration that also includes posts and interactions without needing to move CSV files around, better storage management…) that I’ve wanted in those platforms for a while but I’ve struggled to get merged.
If you follow me here, you can hit the follow button on the new account (and if you don’t, don’t worry, my followers will be migrated at some point between today and tomorrow).

The story of Linux should inspire the Fediverse.
"The year of the Linux desktop" has been a joke for 25 years - a quarter of the century! Yet slowly, and with a persistent following building for linux and supporting it, it's reaching a point where it's no longer something to laugh about - it's a valid choice for many people. Hell, my father (who is 81!) uses ZorinOS, which I installed when windows became too laggy and frustrating for him on his aging PC.
Similarly, if you tell someone that fedi can replace facebook/instagram/x for them, they will probably not take you seriously - most of the people they want to interact with are not here. In the very same way that the apps that people wanted to use on their operating system were not on linux some years ago. Things change - we can change them!
Linux is 35 years old. ActivityPub is less than 10!
Let's build apps and communities for the widespread adoption of the open web, for the fedi revolution. This won't come by itself, we have to prepare it. But we will - we already are!

<p>I have a question for implementors pursuing object integrity proofs.</p>
<p>I am implementing the ability to serve these proofs in NodeBB with the assistance of an LLM. It is adhering to <a href="https://mitra.social/users/silverpill">@<bdi>silverpill@mitra.social</bdi></a>'s <a href="https://w3id.org/fep/8b32" rel="nofollow ugc">FEP-8b32: Object Integrity Proofs</a>.</p>
<p>As part of its work, it implemented a quirk I thought was curious. If the proof was present in an embedded object, the activity's HTTP signature was ignored/not-checked.</p>
<p>I challenged the model and it pointed to this line from the FEP... [133 more words]</p>

ActivityPub.Academy was where many of us checked whether our activities actually arrived anywhere. Thanks @crepels@mastodon.social for running it so well for so long.
We're carrying that forward. @z9mb1@hackers.pub, @2chanhaeng@hackers.pub and I maintain Fedify, and with @gaebalgom@hackers.pub the four of us are building @drfed@hackers.pub, a web platform for developing and debugging #ActivityPub implementations, with NLnet NGI0 Commons Fund support.
Fediverse developers, we hope it earns a place in your toolkit: https://drfed.org/

ActivityPub.Academy is plagued by spam accounts posting hateful and illegal content. I hoped that deleting accounts after one day would prevent this, but I was mistaken. Since I don't have the time to moderate the instance, I unfortunately have to take it offline. I will think about ways to provide the academy in some other form. Until then, you can find the source code on https://github.com/sgrj/mastodon
