Greetings to the Activitypub.space community. I have a question. Is it possible to use Activitypub protocol to define a unique identity on a single account across the various federated platforms, valid for the entire Fediverse?
Been thinking about how Mastodon feels like my memory of the early-90s Internet. Small. Academic. Dispersed. Community-focused. Something a lot of people had heard about, but mostly hadn’t really tried themselves.
In terms of pure numbers it was far from mainstream. And yet, somehow, the most interesting people seemed to be there.

@clemensg et al.
Dieser #Hackathon klingt sehr spannend und die Föderation von #wikidata / #OSM wäre ein schönes Thema mit unseren Bausteinen.

Thinking about building “#Fedify Studio” (tentative name)—a web-based #ActivityPub debugging & development toolkit, like a supercharged version of ActivityPub.Academy and fedify inbox command. Imagine having a proper UI for testing activities, inspecting actors, debugging federation issues… Would this be useful for other ActivityPub developers out there?
@jesuisatire setzt den Minister des @BMDS auf die Schulbank des fedi:
#fediVerse = #Mastodon * #activityPub

#ActivityPub #질문 안녕하세요. ActivityPub protocol에서 유저가 좋아요를 한 게시물을 보는 방법이 있나요? Actor Object에 liked collection을 찾지 못해서 혹시 다른 방법이 있는지 질문드립니다. Every actor MAY have a liked collection. 라고 문서에 나온 것처럼 liked가 필수가 아니라서 보이지 않는 건가요?
Actor Object는 이렇게 확인해봤습니다.
curl -H "Accept: application/ld+json; profile=\"https://www.w3.org/ns/activitystreams\"" \
"https://hackers.pub/ap/actors/0197cae5-cd8e-70f1-adb5-7cbbdd35f81b"
hmmm, I forgot but has anybody made a golang or python translation of the "activitypub as a single PHP file"?

just the basics
First time I’ve heard of Gush!, an activitypub based platform for sharing topical interests for video games. Other media types are being considered for development as well.

@pierobosio sì, è un'ottima risorsa che rende più facile discutere di #ActivityPub
In precedenza, c'era sempre la "categoria" community.nodebb.org/category/…
PS: le categorie del forum si possono seguire dal proprio account mastodon o da altro social federato: per esempio, la categoria activitypub.space/category/2/g… può essere seguita come@general@activitypub.space.
Per farlo, basta incollare il link della comunità nella casella di ricerca del proprio social

@Sascha Ja, klar, logo. Dann würde ich auf Januar 2016 als Geburtsmonat setzen, als das W3C das #ActivityPub-Protokoll vorstellte.
