Letztens lief der Link von #snac2 an mir vorbei. Eine in C geschriebene #ActivityPub Instanz die genau das tut was sie soll: Deine Daten auf Deinem Server halten, klein und sparsam. Für #OpenBSD, #FreeBSD, #Linux.Kein SIgnup, limitiertes, funktionelles Design (hello 90s), kein #Javascript, aber alle Möglichkeiten und komplette Doku in Manpages, Unterset von #markdown, fast beliebige Textlänge und ein anpassbares style.css. Zum selbstkompilieren.

A sneak peak of another #activitypub project I'm working on - a different way of social bookmarking. Coming soon!

#fediverse #fedidev #ruby

🚀 BizzFed.de ist im Early Access!
Ich baue ein föderiertes berufliches Netzwerk auf Basis von ActivityPub – berufliches Networking im Fediverse, ohne zentrale Plattform und ohne Datenkraken.
Aktuell geht es um eins: das Konzept gemeinsam evaluieren. Ich suche neugierige Tester:innen, die mitdenken, ausprobieren und ehrliches Feedback geben.
Lust, Teil der frühen Phase zu sein? Registriert euch!

#Fediverse #ActivityPub #BizzFed #Networking

You, the people, and NLnet, have funded a fully open TikTok alternative with web and mobile clients, ActivityPub federation and an opt-out For You feed algorithm that is privacy friendly.

Anyone can start their own Loops community, and we're working on an official hosting service to help fund development.

If you've been wanting to move your activity history from Strava to FitPub but dreaded dealing with the export files, I made a small browser tool that does the heavy lifting.

Drop in your Strava export files, it decompresses the .fit.gz files, splits everything into correctly-sized ZIP batches, and hands them back for upload. No install, no server, runs entirely in your browser.

Screenshot of the app. Move your activity history from Strava to FitPub. This tool converts your Strava data export into correctly formatted, sized, and counted ZIP batches ready for import.

You know what's pretty cool?

@rabble, the developer of https://divine.video sent a pull request to Loops to improve federation between Divine and Loops.

This is the magic of the open social web.

Collaboration and connection, no matter where you are.

You love to see it ❤️

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.

Self-Hosting an ActivityPub Video Podcast Is Surprisingly Affordable

3/

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.)

Self-Hosting an ActivityPub Video Podcast Is Surprisingly Affordable

4/

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

1/

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

Source code: > https://codeberg.org/fitpub/fitpub

#FitPub #ActivityPub #Fediverse #OpenSource #Cycling #Running #Hiking

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.

https://nlnet.nl/opensocial/

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.

https://forgefed.org

I think ForgeFed is important for this goal

#ActivityPub #Codeberg

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.

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!

Starling as a Fediverse/ActivityPub Server

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)

#Fedilab #HolosSocial

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

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.
