Good read but not a strong fit for writing
Quick Take
This is a deep technical dive into Meta's nanosecond-precision timing infrastructure that's impressive engineering but not directly applicable to Brian's current work or side projects. While the distributed systems concepts around linearizability and consistency are relevant, the specific PTP implementation details are too infrastructure-heavy for his fintech/side project focus.
