Open source technical deep-dives spanning ATProto architecture, DuckDB internals, and the JDK Valhalla project were published.
Analysis
[ATProto/Bluesky] published an article explaining that ATProto has no concept of instances [1]
- Differentiates from Mastodon's instance concept
- Emphasizes separation of hosting and aggregation
- Compares similarity to the RSS/blogosphere model

- As the number of servers c increases
- average latency asymptotically decreases to 1 second
- Analysis based on Erlang's C formula
- p50
- p99
- and p99.9 all show the same pattern
