Recently there has been a lot of dividing & heated discourse about ActivityPub and AT Protocol.
Yesterday at the Social Web CG meeting, I proposed releasing a statement on this discourse, you can read the full statement here:

So uh, is anyone looking to hire a developer with an uncomfortable amount of knowledge about #atproto and #activitypub, experience building from scratch and running a social network (@ludumdare.com), hacking on GPU drivers/network protocols/the Linux kernel, plus a couple decades as a pro gamedev? 🤷

Shit... no job. Ah well, you can't say I didn't try. 🤷

Fico legitimamente empolgado com o fato de que um binário de 93MB feito em Golang + SQlite em uma VPS barata está conectado e trocando informações com 4049 outras instâncias que falam o mesmo protocolo, e que isso não depende de empresa, marca, pessoa, tudo livre, tudo distribuído.

Just closed the #fediversehouse at #sxsw after an amazing two days. Loved being IRL with so many people building the open social web together.

Posting emergency information behind any kind of a login wall is a true failure of government function. I said years ago this would be a great use of a government controlled #ActivityPub instance. You could use #Bluesky too. But the government should be its own platform.
Faine Greenwood @faineg.bsky.social
We should all be yelling at our state officials about the complete insanity of posting vital emergency information *exclusively* on Twitter/X and/or Facebook in 2025. There is absolutely NO good excuse for this. Many, many people don’t use those platforms. Many never did.

Inspired by @pds.dad 's AMA about #atproto over on #Mastodon ... AMA about #ActivityPub and the #Fediverse! No question is too basic! (If questions get beyond my knowledge I'll at least try to point you in the right direction 😃)

Okay, so

According to resources linked in the #Mastodon docs, it seems that signature validation gets the entire #ActivityPub Actor (thus the `#main-key` which the server is supposed to ignore) and then within the Actor it gets the `publicKey` […]

Het is tijd om wat concreter te worden met mijn plannen voor een @nrc_nl Nu vraag ik me af: vinden jullie het minder autonoom / soeverein en dus 'goed' als een toekomstige NRC-server niet op eigen hardware draait, maar in een (verantwoord en lokaal) datacenter? Daar neig ik nu namelijk wel naar […]

Turns out, #Mastodon 's implementation of #ActivityPub just has eveything in a Note's content and contentMap be HTML, so Markdown gets transcribed into <h*>, <strong>, <em>, <code>, etc.
But also, OPTIONALLY, some of those HTML Note also have a mediaType property with value "text/html" so maybe […]

You want to leave the instance your account lives on. There are various reasons why you could make such a decision.
Maybe the admin made a call you disagree with or maybe the instance is shutting down.
What happens to your followers, your handle, and your […]

So, fun fact, if you
* Run Wordpress
* Use the ActivityPub plugin and your SITE gets federated
* Have your cache plugin refresh the cache with every page update
* And enable webmentions
* And get someone with a wide range of followers boosting a post directly from the site to the fediverse (lol […]

YouTube’s sudden ASMR purge proves that building on centralized platforms is renting your business.
Decentralized video is here across #ActivityPub (PeerTube), #ATProto (Streamplace, Skylight), and #Nostr (Zap.stream).
