What is On The Metal?

As a part of starting Oxide Computer Company, Bryan Cantrill and Jess Frazelle decided to also create the podcast that they always wanted. Joined frequently by their boss, Steve Tuck, Bryan and Jess interview incredible guests retelling stories of adventure at the hardware/software interface. It’s unapologetically technical and as Jess says, “the nerdiest podcast on the face of the planet” -- but if you're their kind of nerd, you'll find yourself hanging on every word!
