The Amp Hour podcast's episode #725 features a deep dive with Michał Zalewski, widely known as lcamtuf, a prominent security researcher and author. The primary focus of the interview is his recently published book, 'The Secret Life of Circuits,' which aims to teach electronics from a fresh perspective. The discussion extends beyond the book to cover various aspects of Zalewski's technical interests and career.
- New Book's Philosophy: Zalewski's 'The Secret Life of Circuits' (published by No Starch Press) introduces electronics by starting with FET-based transistors rather than BJTs, aiming for easier comprehension. It also emphasizes deriving formulas from basic trigonometry over calculus, catering to a broader audience.
- Michał Zalewski's Background: The interview touches upon his prolific writing on his Substack and his famous CNC guide. His career in information security, including early-day fuzzing and significant security books like 'American Fuzzy Lop' and 'The Tangled Web,' is also discussed, highlighting the aging nature of security knowledge versus the enduring principles of electronics.
- Niche Technical Interests: Zalewski shares his fascination with calculators, delving into their history, dead ends in their development (like CRT displays), and the evolution from discrete components to processors, including his collection of rare mechanical calculators.
- Practical Projects: The conversation highlights several of Zalewski's personal projects, from building a clock out of current meters to other creative endeavors like woodworking integrated with AI, and microcontroller-based games like Sokoban.
The interview provides a comprehensive look into Michał Zalewski's multifaceted expertise, spanning from his pedagogical approach to fundamental electronics and his deep contributions to cybersecurity, to his passion for historical computing and practical engineering projects.
