The Sidecar Switch
Oxide and Friends Twitter Space: November 29th, 2021
The Sidecar Switch
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 November 29th, 2021.
In addition to Bryan Cantrill and Adam Leventhal, our special guest was Arjen Roodselaar; other speakers on November 29th included Rick Altherr, Simeon Miteff, MattSci, Jason Ozolins, Thomas and Edwin Peer. (Did we miss your name and/or get it wrong? Drop a PR!)
