Hanselminutes with Scott Hanselman

Scott talks with Skyla Loomis, General Manager of IBM Z Software, about the ongoing relevance of mainframes in 2026. They discuss the enduring power of mainframes, how generative AI is transforming COBOL modernization, and why enterprise infrastructure still runs on IBM Z. Skyla shares insights on developer experience, compliance challenges, and the misconceptions about mainframe technology in a cloud-native world.

Join Scott and Eric Lippert for a lively tour through Fabulous Adventures in Data Structures and Algorithms, a fresh take on timeless topics that flips the script on how programmers think about core tools of the trade. Eric shares why he wrote a book that avoids the predictable interview-prep regurgitations, and instead dives into clever, lesser-known data structures and algorithmic ideas that he’s encountered over a long career in language design and tooling. You’ll hear how immutability can make data structures both simpler and faster, why backtracking shows up everywhere from tree search to puzzle solving, and how a deeper understanding of performance and abstraction can change the way you architect code. Along the way Eric reveals how to reconnect joy with problem solving, find surprising patterns that scale across domains, and build intuition that serves you long after the syntax fades from memory.

Why are so many developers suddenly talking about Zig? Is it just another systems language, or is something deeper happening? Scott sits down with Loris Cro, one of the community voices behind Zig, to explore why this relatively young language is getting so much attention from systems programmers, game developers, and performance-obsessed engineers alike. We dig into Zig’s radical focus on simplicity, explicitness, and control...and why not having features like a garbage collector or hidden magic is actually the point. Loris explains how Zig approaches memory safety, cross-compilation, and interoperability with C in a way that feels refreshingly honest, and why Zig’s philosophy resonates in a world increasingly shaped by complex toolchains and opaque abstractions. Along the way, we talk about the cultural moment Zig is emerging into, what developers are really asking for in 2025, and whether Zig represents a return to fundamentals, or a glimpse of the future.

Marcus Fontoura has led engineering teams at IBM, Yahoo, Google, and Microsoft...building the very systems that power our digital lives. Now, as the author of Human Agency in a Digital World, he’s asking a more profound question: how do we stay in charge of the technology we create? Scott and Marcus explore what it means to move from being passengers to pilots in an age of automation — through ethics, education, and intentional design.

Scott sits down with Camille Tomlin, Head of IT at Philadelphia International Airport, to explore the intersection of aviation, technology, and leadership. They discuss how airports are transforming digitally — with IoT, data analytics, and smart infrastructure — and how Camille leads a team that bridges city government, airlines, and millions of passengers every year.

Postgres has quietly become the world’s favorite database...running startups, governments, and global clouds alike. Scott talks with Claire Giordano, long-time Postgres advocate and technologist, about the database’s unlikely rise from academic roots to modern dominance. They explore its design philosophy, the open-source community that fuels it, and why Postgres keeps winning even in the age of AI and hyperscale data.
