Big community events only work because people step up behind the scenes.
This year, at @owasp Global AppSec EU Vienna ( #OWASPVienna26 ), I had the privilege of coordinating an incredible team of volunteers: people offering their free time to make this event the best it could possibly be.
And they did an outstanding job.
Everything went smoothly, and we managed to hide all the little background

Friction is good. Some things take time, and that’s okay. Everyone in the tech industry needs to calm down. Perpetual acceleration only ends with you eventually going up in flames.
I’m honored that my #sec4dev 2022 talk, “Typed Security: Preventing Vulnerabilities By Design” (https://www.youtube.com/watch?v=TCc6gbTtK8o), is mentioned in Tanja Janca’s (@SheHacksPurple) book, “Alice & Bob learn Secure Coding”.
