We talk to Kevin Riggle (@kevinriggle) about complexity and safety. We also talk about the Twitter acquisition. While recording, we discovered a new failure mode where Kevin couldn't hear Thomas, but David and Deirdre could, so there's not much Thomas this episode. If you ever need to get Thomas to voluntarily stop talking, simply mute him to half the audience! https://twitter.com/kevinriggle Transcript: https://beta-share.descript.com/view/WTrQGK4xEVj Errata It was the Mars Climate Orbiter that crashed due to a units mismatchDavid confused the Dreamliner with the 737 MaxLinks https://free-dissociation.com/blog/posts/2018/08/why-is-it-so-hard-to-build-safe-software/https://complexsystems.group/https://how.complexsystems.fail/https://noncombatant.org/2016/06/20/get-into-security-engineering/https://blog.nelhage.com/2010/03/security-doesnt-respect-abstraction/http://sunnyday.mit.edu/safer-world.pdfhttps://www.adaptivecapacitylabs.com/john-allspaw/https://www.etsy.com/codeascraft/blameless-postmortemshttps://increment.com/security/approachable-threat-modeling/https://www.nytimes.com/2022/11/17/arts/music/taylor-swift-tickets-ticketmaster.htmlhttps://www.hillelwayne.com/post/are-we-really-engineers/https://www.hillelwayne.com/post/we-are-not-special/https://www.hillelwayne.com/post/what-we-can-learn/https://lotr.fandom.com/wiki/Denethor_IIhttps://twitter.com/sarahjeong/status/1587597972136546304"Security Cryptography Whatever" is hosted by Deirdre Connolly (@durumcrustulum), Thomas Ptacek (@tqbf), and David Adrian (@davidcadrian)
