Prodfiler is a new tool that provides fleet-wide full-system continuous profiling. It is in some ways the second act of its co-creator Thomas Dullien, who is an internationally-renowned reverse engineer and vulnerability researcher under the name Halvar Flake. Thomas joins us to discuss his career, what you should profile in a distributed system, and why you can’t sell something with a negative cost.
