Hmm, has anyone made an compatible server for play-by-post RPGs? That way people can follow along if they want, people could run their own server if they wished, but mainly as an alternative to discord which is where so many modern pbp games are hosted.

@ricmac #Madblog has native support for #Webmentions, and unlike #ActivityPub they’re enabled by default.

I’ve tried to make it as simple as possible and avoid manual callbacks or special tags for mentioned links.

You put a link in an article, and when you save it Webmentions are sent to supported targets. Someone mentions your article from a place that supports Webmentions, and the mention is stored on your blog.

en revenant sur le site, je me suis rappelé le besoin de veiller toujours à la cohérence #likes #fediverse #webmentions #activitypub

Spaßige Fediverse-Beobachtung des Tages: Wenn du auf Mastodon fragst „Welche Instanz soll ich nehmen?" kriegst du 47 durchdachte, freundliche Antworten. Wenn du dasselbe auf Twitter/X fragst… naja. 🐘

Das liegt übrigens nicht an Zufall – dezentrale Netzwerke ziehen andere Communities an, weil die Plattformstruktur selbst das Verhalten formt. Algorithmen ≠ neutral.

Gualaaaaa, ya empieza a tomar forma #FediPhoto

una fedi aplicación super ligera para publicar una foto (y sólo una) cada día, apta para correr en una raspberry, un vps mínimo o donde quieras

Admite Follow, UnFollow y notifica cuando hay una foto nueva

Publicar una foto es tan fácil como copiarla en la carpeta "inbox" donde esté desplegada la aplicación y chimpón, la envía a tus followers

Le quedan algunas cositas y subo el código

p.d.
NO sirve para nada más que para que yo practique con el #ActivityPub

"If you want to be in the Fediverse without relying on big intances, or if you just want to own your #data & #identity on the network, running your own instance is the way to go.
That is where Mastodon alternatives such as GoToSocial & #snac comes in.
snac (Social Networks Are Crap) is a minimalistic, lightweight #ActivityPub instance…perfect for single user instances or small communities, and it's so light that even a #RaspberryPi can handle it without breaking a sweat."

I’m also exploring ideas like:

• leaderboards
• activity points
• community challenges

Possibly as a component integrated with BadgeFed + Fediprofile, or maybe as a separate project.

Still experimenting.

--

In short:

BadgeFed issues decentralized recognitions.
Fediprofile helps people collect and display them.

Both use #ActivityPub as the backbone.

Badges become portable, social, and decentralized.

And communities can build on top of that.

--

P.S. I decided to NEVER add a wallet into BadgeFed, keeping it simple and extensible by default. So Fediprofile is the default wallet. But anyone can build and use their own. No new specs, no new protocols.

Badges themselves are very simple files.

Often the badge information is encoded inside an image, usually a PNG.

So the image contains both:
• the visual badge
• the structured metadata describing the credential

One file, both human-friendly and machine-readable.

Other times these are simple json files.

--

Where things get interesting is with #ActivityPub.

@badgefed uses ActivityPub as a transport layer for decentralization, and also as a way to add social features.

BadgeFed issues credentials, but it wraps the OpenBadge inside an ActivityPub Note.

The actor creating that note is the badge issuer. <-- important!

--

This is actually very similar to how a Mastodon post works when you post a image.

Imagine:

• the image = the badge
• the post = the description of the recognition

Once published, anyone in the #Fediverse can interact with it:
reply, comment, like, boost, quote, or follow (and block) the issuer.

Badges become social objects.

I think it's a good time to explain how we see @badgefed and @fediprofile, how they work together, and how #badges can use #ActivityPub and the #Fediverse.

Also how this can help communities outside the fediverse!

This is a quick overview of the architecture and ideas behind it. 🧵 1/

(thanks @johannab for the ask ...)

Meta-question: if I boost a post, sometimes I end up seeing all the replies to it in my mentions, and I have to mute the thread.
It only happens sometimes though. How do I stop that happening?

Webmentionnons-nous les uns les autres

Le site vient de rejoindre il y a peu le Fédiverse (fédération d’univers, de réseaux, de serveurs indépendants capables de communiquer entre eux). Dans l'idée d'approfondir notre indépendance vis à vis des géants du Web, je me suis intéressé aux webmentions. Et quand je dis "webmentionnons-nous les uns les autres", c'est une façon de nous inviter, auteurs de sites et de blogs à mieux nous relier quand nous nous citons. Webmention ? Webmention ? Est-ce que j'ai une gueule de […]
