Integrating trust into ATProto cooperative governance

TrustNet plus Semaphore on ATProto custom lexicons is the most practical foundation for CSN V5's trust network, combining subjective multi-dimensional trust scores, anonymous ZK-based voting, and verifiable append-only audit logs — all implementable in your TypeScript/Express/PostgreSQL stack without blockchain dependencies. The ATProto ecosystem's lexicon extensibility, labeler infrastructure, and January 2026 DID:PLC streaming API provide the protocol-level primitives needed to make trust a first-class citizen of the federated network. Real-world cooperative governance patterns and hard lessons from fediverse trust systems (SourceCred's collapse, The Bad Space controversy, IFTAS's funding crisis) point toward a tiered, human-in-the-loop trust architecture where algorithmic scores inform but never replace democratic membership decisions.

Benchmarking Leiningen on Apple Silicon

Gene was tweeting about Clojure's startup performance on Apple Silicon, so I decided to benchmark my new MacBook Air with the M1 chip against my Intel based MacBook Pro.

TL;DR

The M1 chip in the MacBook Air - which lacks a fan - was able to quite tidily beat an almost top-of-the-line Intel chip.

gif-from-tweet

There are so many great GIFs out there and I want to have copies of them. Twitter makes that harder than it should be by converting them to MP4 and not providing access to the source material. To make it easier, I made a bash pipeline that takes a tweet URL and a filename, extracts the MP4 from that tweet and uses ffmpeg to convert back to GIF.

Dependencies

• ffmpeg
  • macOS: brew install ffmpeg
  • Ubuntu/Debian: apt install ffmpeg
