Oxide and Friends Twitter Space: January 10th, 2022

Flying Blind with Peter Robison

We’ve been holding a Twitter Space weekly on Mondays at 5p for about an hour. Even though it’s not (yet?) a feature of Twitter Spaces, we have been recording them all; here is the recording for our Twitter Space for January 10th, 2022.

In addition to Bryan Cantrill and Adam Leventhal, our special guest was Peter Robison.

Other speakers on January 10th included MattSci and Simeon Miteff. (Did we miss your name and/or get it wrong? Drop a PR!)
