from /proc to proc_macro
We’ve been holding a Twitter Space weekly on Mondays at 5p for about an hour. In addition to Bryan Cantrill and Adam Leventhal, speakers included Brian Cantrell (not making that one up!), Nima Johari, Joshua Clulow, Laura Abbott, and Tom Lyon. The recording is here.
(Did we miss your name and/or get it wrong? Drop a PR!)
