Layer2C Labs 001: Borrow the Vendor’s Plumbing, Not Its Judgment
A replay of Layer2C Labs episode 001 on The CTO Advisor feed. The managed data plane is cheap and fast; the cost it hides is the chunking judgment it takes from you. Keith Townsend built a retrieval pipeline over thirteen years of Tech Field Day transcripts, about 237,000 segments, split between Amazon S3 Vectors and an NVIDIA DGX Spark on his desk, and traced where the decisions actually landed. Written by Keith Townsend and narrated by AI — the voice isn’t his and isn’t pretending to be. The full lab, with every number: https://labs.layer2c.com/labs/spark-s3vectors
