Michał Zalewski — known online as lcamtuf — is one of those rare technologists whose work has shaped entire disciplines without him ever seeking the spotlight. For two decades he was a fixture of the security world: author of Silence on the Wire (still one of the most original books ever written on passive network reconnaissance), creator of afl-fuzz (which arguably kicked off the modern coverage-guided fuzzing era and found bugs in nearly every piece of widely-used C software on the planet), and a longtime director of information security at Google.

What makes this Amp Hour episode worth your time is that it's not a security interview. The Amp Hour is a hardware/electronics podcast, and Zalewski has spent the past several years quietly pivoting into analog and digital electronics — writing some of the clearest tutorials on the subject available anywhere on the open web. His site has become a go-to reference for engineers trying to actually understand what's happening inside op-amps, transistors, and feedback loops, rather than memorizing cookbook formulas.

Listeners can expect discussion of:

• How a career security researcher ends up obsessed with circuit-level intuition
• Why so much electronics pedagogy is broken, and what a better approach looks like
• The overlap between fuzzing mindsets and debugging analog hardware — both are exercises in probing systems whose behavior you don't fully trust
• Self-directed learning at a deep technical level, well past the point most engineers stop

For a technical audience, the appeal is twofold. First, lcamtuf is a genuinely original thinker — his explanations tend to dissolve confusion rather than paper over it. Second, the interview captures a fairly rare archetype: the senior software person who decided that understanding the physical substrate was worth years of effort, and who can articulate why. If you've ever bounced off an electronics textbook, or wondered whether the security-mindset transfers to hardware, this is an hour well spent.

The Amp Hour's long-form format means you get the actual reasoning, not soundbites — which suits a guest like Zalewski, who tends to think out loud carefully.
