jrollans.com is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.

Self-Hosting an ActivityPub Video Podcast Is Surprisingly Affordable
2/
A typical 1-hour podcast episode at 1080p 60 fps is around 5.4 GB.
At one episode per week, that's about 280 GB per year.
Even after 5 years, your entire podcast archive would only use about 1.4 TB of storage.
That is it.

A 2 TB hard drive is often available for around $50–$60, which is enough space for five years of weekly episodes.
Need more room?
4 TB, 8 TB, 12 TB, and even 16 TB drives are widely available and far more affordable than most people expect. (Ex: 8TB is about $130 to $170.)

When you look at the actual storage requirements, self-hosting a video podcast on the Fediverse starts to look a lot less intimidating — and a lot more realistic.
It is affordable — especially with your own HomeLab (where you buy your own hard drives rather than rent them).
Self-Hosting an ActivityPub Video Podcast Is Surprisingly Affordable

Imagine this.
You want to launch your own video podcast.
A new episode every week.
Each episode is 1 hour long.
Full HD (1080p), 60 fps video.
What would it cost to host it yourself?
Before I ran the numbers, I assumed it would be expensive — maybe even impractical.
I was wrong.
The reality is surprisingly affordable.
Here is why.

FitPub 1.0 is here! 🚴🏃🥾
FitPub is a federated social fitness platform and Strava alternative built on ActivityPub, giving athletes control over their data, communities, and connections.
Today also marks the launch of the first official FitPub instance: > https://fitpub.social

Now running both Activitypub and Atmosphere on my blog so it should be visible from Bluesky and Mastodon. In theory replies on both should be come comments visible on the blog post but there might be some weirdness. #Uncategorised #Activitypub #Atmosphere #Bluesky #Mastodon #Wordpress
A reminder to #ActivityPub developers and advocates: applications for the NLNet Open Social Fund close on June 1st (#BrookeVibberDay) at noon CEST. You should apply; you are doing important work and we need you to keep doing it.
I have seen the @Codeberg people say they don't want to be the only code-forge.
I.e., they don't wan to replace GitHub. They want there to be many code-forges out there, including them.
I agree with this goal.
But — I think until we (at least) have federated pull-requests, this is less likely to happen.
And, I do know that there is an effort to add ActivityPub support to Forgejo, Gitea, and others.
I think ForgeFed is important for this goal
I am now running both ActivityPub and ATmosphere plugins on this website now, each enabling the blog to be visible across both protocol types. For activity pub it should show to Mastodon / GotoSocial instances and ATmosphere will show to Bluesky (and possibly Threads but not sure). interestingly the plugins work in a slightly different way.
ActivityPub is probably the more tightly integrated plugin, it doesn’t need another account to post through like ATmosphere. It does however currently need other plugins, friends and enable mastodon apps to give a total experience, for example being able to do non-blog posts and see others feeds in an app. I have found Phanpy to be the best solution for interacting with the ActivityPub plugin.
The closer integration does allow for some interesting blocks supplied for the plugin, for example a follow pane:
and also lists of followers and those I follow:
One of the tricker problems was there wasn’t a ‘profile’ page to point people at, in the same way as your mastodon profile. This has been added, you can see mine at here, although it still remains harder to follow from here than it would be through a traditional mastodon instance.
The Atmosphere approach is slightly different as it posts through, and scrapes comments back from an ATmosphere PDS, for example Bluesky using the AT protocol. Mine is @mark.hysted.com. The outcome is basically the same, posts are sent out via my Bluesky profile and comments come back to be added in the blog post. This is a more recent plugin, only just released so there isn’t the blocks that ActivityPub has – but I expect those are in train.
I’m not sure how this all works together, are comments made on Bluesky federated to Mastodon and can those be replied to? Am I causing chaos across the two approaches and also creating a burden on my WordPress site that will mean a performance upgrade? Feel free to add replies and test how things work between the two different plugins and ecosystems. Also shout if you see any weirdness!
PS – Most of my recent blog posts seem to be about blogging, I promise this will be the last for a while.

Hello Fediverse! #Introduction 🚀
I’m Jim, full-stack dev building out of Knoxville, TN. Heads-down initializing Cipher CTS—a decentralized, offline-first AI platform.
We are actively moving past legacy constraints by running highly compressed ternary BitNet models natively on consumer hardware. No multi-billion dollar server farms, no data harvesting, and zero corporate API dependencies. Scaling our communication layer over #ActivityPub web hooks with a stateless proxy network.
Pushing hard toward a public release for Summer 2026. Follow along here for open-source technical logs, model benchmarks, and system updates! 🌲
#CipherCTS #Devlog #localFirst #ternary #BitNet #SelfHosted
Is there an actively-maintained, relatively lightweight #Fedi / #ActivityPub server I can run under plain Debian without using Docker?
Asking for a friend (who is actually me, but a hypothetical "me" who has time to fart around spinning up and maintaining new services).
Building #HolosSocial is by far my most ambitious project. It might only attract a niche of users, though at first it could seem strange to run an #ActivityPub server on a device.
But Holos' purpose is more than that: helping everyone have their own identity, host their media, and not depend on a server admin. Make everything accessible with views depending on your mood. One app, one identity, with all that the fediverse can offer.
That's the beginning, the way is still long but not unreachable.

Wie würdet ihr zu einem beruflichen Netzwerk in Fediverse stehen? Ich würde es thematisch interessant finden eine extra Plattform zu haben die sich darauf konzentriert, inklusive Stellenanzeigen etc., jenseits vom BigTech Anspruch. LinkedIn/XING

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)
(1/4)
Multi-device support is progressing well for #HolosSocial. The tricky part: each device runs its own #ActivityPub server, with its own local data, signing its own activities. Keeping several servers in sync both ways, without duplicating everything, without losing actions on the way, and without two of them handling the same activity at the same time, was the main problem to solve. It also had to stay reliable when a device goes offline for hours or days.
(1/3)
Plusieurs ajouts importants dans la dernière mise à jour
- 📅 Les flux ics par profil sont en place, permettant de synchroniser son compte #mobilizon pour poursuivre la collaboration entre les deux projets (prochaine étape: alimenter son profil avec #mobilizon
- 📅 Les évènements peuvent être partagés par email, avec ICS en attachement pour ajouter au calendrier
Objectif: augmenter la portée de vos évènements, offrir de nouveaux outils de #diffusion, et supporter #activitypub 🔥🔥🔥
The Fediverse is so cool. The interoperability of ActivityPub rewards you from browsing other instances, creating server-side and personal connections differently from how we were taught to browse the social web.
At the moment I'm trying to figure out the most optimal way share content around the Fediverse, from Peertube to Mastodon in particular. How it works is kind of weird.
#Fediverse #ActivityPub #Peertube #Mastodon #Interoperability #SocialWeb #Federation #Federated #FederatedSocialWeb
This is cool as hell! https://ieeexplore.ieee.org/document/10361296 #ActivityPub #IOT #UPOD
This is the discussion thread for the draft FEP-baf5: Administrator Collection
This FEP introduces a mechanism for discovering the administrators of an ActivityPub instance. It extends the "Group Moderator" pattern from [FEP 1b12][1b12] and the "Application Actor" concept from [FEP 2677][2677] by defining an
OrderedCollectionof administrators referenced from the instance's application actor.
#HolosSocial isn't bringing something new to the #Fediverse, especially not to #ActivityPub. It builds on what exists, without mimicking any platform.
Every social network has been given its fediverse clone. Asking people to hold a separate account on each is taking the problem backwards.
If the fediverse keeps mirroring the GAFAM, it loses. The point was never to rebuild their world, but to offer something else: one identity across every content.
HolosSocial is simply a try. But we can do it.
FEP-fe34 (Origin-based security model) update : https://codeberg.org/fediverse/fep/pulls/849
I tried to better explain the assumptions on which the model is based, and clarified how exactly origins should enforce boundaries between actors:
Servers MUST ensure that activities published by a client do not represent unauthorized actions. This includes activities embedded within other activities and objects.
Servers MUST NOT allow clients to publish activities where embedded objects are owned by another actor.
Lemmy API and Mastodon API implementers don't have to worry about this, but one needs to be very careful when accepting arbitrary payloads from clients, for example, when implementing ActivityPub C2S API or FEP-ae97 API. Unfortunately, these security issues are completely ignored by people who push for wide deployment of ActivityPub C2S API.
Another addition is the recommendation to not use partially embedded objects, because that might lead to cache poisoning:
Embedded non-anonymous objects SHOULD NOT be partial representations. A server that relies on embedding for authentication might save a partial representation of an object to the cache, replacing the full object.
(see this issue for details: https://codeberg.org/silverpill/feps/issues/21)
#Starling is a lightweight #PHP #fediverse server you can install by just copying files over FTP to a shared host. No PostgreSQL, no workers, no DevOps. Owning your data with #ActivityPub can be much simpler than with #ATProtocol. Have you tried it?

Started working on bringing ActivityPub Polls to NodeBB 
First step is adding in separate handling of the Question object. Right now NodeBB treats it as a "Note-like" and renders it like a post
50% of the way there... will need to link it to nodebb-plugin-poll...
One complication... the plugin ties votes to users. This data isn't reflected over-the-wire in AP, only the aggregate voter counts are shared
[...]
Hollo announces: Hollo 0.9.0 is out. https://hollo.social/@hollo/019e451e-f368-70e2-b993-77d01a14a677 #hollo #fediverse #ActivityPub
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.
If you find #snac useful, please consider buying grunfink a coffee or contributing via LiberaPay.
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.
