Monica McGuigan, a Scala programmer at JP Morgan, talks with Richard about her experiences learning Roc with a Scala background. They get into topics like how language design affects beginners and experts, what parts of functional programming are easier and harder to learn than others, and how language designers inform their design decisions.

Mike Bryzek has been a technical cofounder of two very successful companies using some very unorthodox technical strategies that have worked out very well for him and his teams! These include testing in production, spending the first few months of a brand-new company's life investing in automation and tooling before shipping a product, and microservices - but not done in the way I've usually heard them described.

Richard talks with Will Sentance, the teacher of the Hard Parts series and the founder and CEO of CodeSmith, which is a Software Engineering and AI immersive education program. They talk about how AI is intersecting with modern programming education, what's considered "fundamentals" these days, and how Will thinks about teaching object-oriented and functional programming.

Richard talks with Kyle Boddy about the biomechanical and data analysis software Kyle wrote—and continues to write—as the founder and CTO of Driveline Baseball, a data-driven player development company that has landed numerous players in Major League Baseball, including multiple Most Valuable Players and 2024's number one draft pick. They talk about Kyle's background in PHP and the C++ he wrote to coordinate budget high-speed cameras back when Driveline was a one-programmer garage shop, up through today where large language models have become an integral part of the development team's daily work.
