Why do we want to grow the open social web, and for whom? @ben says the value is in protocols that allow people — all people around the world — to build and own communities that address their needs. "The only way to achieve that is to not just co-design with them but distribute equity. They must be full co-owners of the open social web," he writes.

Maybe something to clarify with #HolosSocial. There is a full moderation system like on any Fediverse instance. Moderators can ban accounts. But relays are dumb by design: your identity and data belong to you, not to the relay. A ban is like a relay going down, you don't lose everything. You can move to another relay and keep all your followers, following, and data. With a custom domain the transition is seamless, otherwise it works through standard #ActivityPub migration.

RE: hachyderm.io/@thisismissem/116

This is such an interesting thread as it exposes the friction between ATProtocol/ActivityPub. Clearly, there are some cultural issues.

It's important to understand and I say this often to our own desktop projects - we are always stronger together than apart.

We are not competitors. We are allies.

Understandably we might compete on investment and volunteers but those sort themselves.

RE: indieweb.social/@data0/1158843

Last reminder: Are you using fedi-followers.data0.one ? If you do and want to continue using it, please migrate to the #ipns domain (more info in the quote toot below). The data0.one domain will be gone next week.

Observations:

Today #bigtech social media looks & feels like TV to me. Consume whatever each platform owners' algorithms serve.

#ATProto's ecosystem seems focused on reach & broadcasting. #ActivityPub's ecosystem seems focused on interaction. Is this the diff between #SocialMedia Vs #SocialNetworks? Newschool vs Oldschool Internet?

Would be nice if these #protocols become interoperable. Technically solvable, but I wonder are the 'cultures(?) 'interoperable as well? Thoughts?

Before I drive myself mad and try to build something I'm incapable of…

Has anyone built an server for embedded devices?

Not a Raspberry Pi, but like one of those tiny ESP32 devices which can run MicroPython or similar.

I built a *full* AP server in around 64KB of PHP
gitlab.com/edent/activity-bot/

Now I'm wondering if a tiny sensor could be a fully-fledged ActivityPub node on the Fediverse.

I've just updated my #Snac instance to stable version 2.90 👍 🎉
You don't know Snac? But you should: https://codeberg.org/grunfink/snac2
A simple, minimalistic and well documented #ActivityPub instance server written in C, no database needed, totally JavaScript-free, no cookies either, not much bullshit.
A lot of fixes, tweaks and changes in this version, quick and easy update, as usual.

@Shizanit, виявляється що peertube.in.ua є частиною цього проєкту, як і Git хостинг. Цікаво, чи не розглядали також і опцію створення федеративних блогів на базі #Plume або схожих рушіїв на базі технології #ActivityPub?

Пишу деякі гайди, і думаю що найкраще робити це в соціальній екосистемі а не окремому сайті

O Mastodon não implementa o C2S

Eles implementaram só o S2S (Server to Server / Protocolo ActivityPub) e criaram a própria API REST no lugar do C2S.
Isso é uma decisão deliberada deles — e é bastante criticada na comunidade ActivityPub por ser exatamente isso: uma quebra do spec.

A especificação do #ActivityPub já prevê uma "API padronizada". Ao pedir o Activity Stream do usuário logado, é pra vir uma URL que permite escrita no outbox. É essa parte que o #Mastodon não implementa.

O objeto Activity Stream do usuário logado já traz todos os dados que você precisa pra usar a API daquela implementação específica.

Então, a regra é ser capaz de consumir a API do ActivityPub a partir de qualquer cliente. A exceção é o Mastodon.
