Episode 156: Stateless Validation with Alin Tomescu

In this week’s episode, Anna and Fredrik chat with Alin Tomescu, a post-doc researcher at VMWare Research Group, about the concept of stateless systems. Specifically, they explore his work on stateless validation, why this would be desirable and what is the state of the research around this topic.
