The Pragmatism of Hubris

Oxide and Friends Twitter Space: December 13th, 2021

The Pragmatism of Hubris
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 December 13th, 2021.
In addition to Bryan Cantrill and Adam Leventhal, speakers on December 13th included special guests Cliff Biffle and Steve Klabnik as well as Laura Abbott, Rick Altherr, James Tucker, Simeon Miteff and MattSci. (Did we miss your name and/or get it wrong? Drop a PR!)
