What happens when you build a computer without a CPU? John Calhoun spent 25 years as an engineer at Apple, then dove deep into analog computing out of pure curiosity — and built his own. He'll walk through the fundamentals of analog computing and the process of building one, with physical analog computers doing their thing along the way. Think less PowerPoint, more science fair for computer nerds.
The voice traffic on Omaha's P25 radio network is encrypted. The metadata is not. Gus shows what you can learn with a software-defined radio and some patience, without decoding a single voice packet.
Adam submitted a talk to a security conference and noticed something odd in the CFP platform. A little poking around revealed he could see data he had absolutely no business seeing. No fancy tooling. No advanced techniques. Just a browser, some curiosity, and a web application that trusted its users a bit too much. The punchline writes itself.
Levi is a security engineer, not a developer. So when he needed a tool to keep up with the flood of threat intel, vendor advisories, and LLM news, he built one anyway using Claude Code as his pair programmer. What started as a course project became something he actually runs in production. This talk is an honest account of that journey, including what worked, what broke, and what surprised him along the way.
