On The Metal / Jon Masters

Description

On this episode of On the Metal, we interview Jon Masters, computer architecture raconteur, microprocessor enfant terrible, and Patron Saint of Lost Computational Causes. Join us as we learn why Jon hates simultaneous multithreading, why he loves UEFI (?!) -- and when we can expect the supremacy of the quantum blockchain.
