We’re throwing a party in Vegas! Someone called it SCWPodCon last year, and the name stuck. It’s sponsored by Teleport, the infrastructure identity company. Get SSO for SSH! If Thomas was here, I’m sure he’d tell you that Fly.io uses Teleport internally. Oh also there's some thing called Black..pill? Black Pool? Something like that happening in Vegas, with crypto talks, so we chatted about them a bit, plus some other stuff

It seems like everyone that tries to deploy end-to-end encrypted cloud
storage seems to mess it up, often in new and creative ways. Our special
guests Matilda Backendal, Jonas Hofmann, and Kien Tuong Truong give us a tour through the breakage and discuss a new formal model of how to actually build a secure E2EE storage system.

Migrating the US government to quantum-resistant cryptography is hard, luckily the gamer presidents are on it. This episode is extremely not safe for work, nor does it reflect the political opinions of, well, anybody.
