I did an interview with the @defcon.bsky.social video team during #DEFCON 33. In the video we discuss open source software in the federal government, the issues government faces, and how we can do better! It's basically a 15 minute version of my 45 minute conference talk. 😂 youtu.be/bsls-3hXH4M?...

My @defcon.bsky.social haul: Stickers, coins, patches, badges & all the miscellaneous awesomeness like plushies, CDs, floppies, bottle openers and a handcrafted satchel from my Hacker friends in Kazakhstan! 😊 I’m truly thankful for every one of these! Each one a token from a friend! 🥰
