Mysteries of Memory and the Evolution of Scooby-Doo

Two years ago, the Oxide team encountered data corruption during a fairly simple network data transfer. The ensuing debugging sessions uncovered a truly bizarre bug involving CPU speculation! Bryan and Adam were joined by colleagues John and Rain to discuss the discovery and circuitous hunt to track down the bug.

In addition to Bryan Cantrill and Adam Leventhal, speakers included John Gallagher, and Rain Paharia.
