What I Wish Someone Had Told Me About AT Protocol and Bluesky - Stuff Rob Wrote
I've been interested in atproto (the protocol that Bluesky, Blacksky, and many other applications - including pckt, where this blog is hosted! - run on) for abo...

From ZK-first to AT Protocol — our path to DDS | Agora Citizen Network
We've been building Agora — a platform for public deliberation using Polis-style clustering — for a while now. Along the way, we've written about what we think about Nostr, AT Protocol, Polis, Community Notes, and protocol interoperability. Those posts are somewhat outdated now. This one describes w...
The Algorithm, Singular
A new European ruling on algorithmic amplification determines if an operator controls how content spreads on a platform. But applying it to open social networks turns out to be a problem.

AT Protocol
The AT Protocol is a protocol and open standard for distributed social networking services. It is under development by Bluesky Social PBC, a public benefit corporation originally created as an independent research group within Twitter, Inc. to investigate the possibility of decentralizing the service.
Requisite variety and its implications for the control of complex systems
Recent work on the fundamental processes of regulation in biology (Ashby, 1956) has shown the importance of a certain quantitative relation called the law of requisite variety. After this relation had been found, we appreciated that it was related to a theorem in a world far removed from the biological—that of Shannon on the quantity of noise or error that could be removed through a correction-channel (Shannon and Weaver, 1949; theorem 10). In this paper I propose to show the relationship between the two theorems, and to indicate something of their implications for regulation, in the cybernetic sense, when the system to be regulated is extremely complex. Since the law of requisite variety uses concepts more primitive than those used by entropy, I will start by giving an account of that law.
