On the Biology of a Large Language Model
We investigate the internal mechanisms used by Claude 3.5 Haiku — Anthropic's lightweight production model — in a variety of contexts, using our circuit tracing methodology.

The Logfile Navigator
The Logfile Navigator, lnav for short, is an advanced log file viewer for the small-scale.

ATOM: AT Protocol Over MoQ Transport
This document specifies how the Authenticated Transfer (AT) Protocol can leverage Media over QUIC Transport (MOQT) for efficient data synchronization across decentralized social networks. The AT Protocol's firehose event stream and repository synchronization mechanisms map naturally to MOQT's publish/subscribe model, enabling scalable relay infrastructure, priority-based delivery, and improved resilience for large-scale social data distribution. This specification addresses the challenges of the current WebSocket- based transport and demonstrates how MOQT's relay architecture, group-based caching, and multiplexed streams provide significant benefits for AT Protocol deployments at scale.

ENDOGEN: a deep experimental exploratorium of lowercase synthesis - CDM Create Digital Music
Enter an organic sound machine that will take you to an imagined sound world somewhere between a temple garden and a half-awake dream. ENDOGEN is a dazzling tool, built in Max and SuperCollider, that explores notions of lowercase synthesis. There's a lot to cover as far as what it can do -- but you should also feel empowered to play and get lost.

Cooperative playlists
I’m working on collaborative audio playlists and was wondering if this design makes sense for atproto. How it works Two lexicons of importance: sh.diffuse.output.collaboration sh.diffuse.output.playlistItem sh.diffuse.output.playlistItem has the following properties (besides the usual id, etc): criteria: which audio track to match with. playlist: the name of the playlist this item belongs to. positionedAfter: the id of the item to position this one after (none = start) The way we as...

[Proposal] Shared private Data for social posting
seconding a sidecar private PDS endpoint attached to the DID document as a good approach in the general case (in an implementation of private data I did which never saw the light of day, this was the approach I took), though obviously it imposes additional constraints on a first mover building this out.

A Model for addressing privacy on ATproto
When I first got involved with Northsky social, we knew we would have to eventually address the elephant in the room. How do we proactively protect a community from outside influences without relying purely on moderation? And more importantly, how do we keep bad actors from simply pulling their data straight from a relay?
