Hanselminutes with Scott Hanselman

Scott talks with Nathan Sobo, CEO and co-founder of Zed, about what comes after the traditional code editor. They start with Zed’s vision for a fast, collaborative, AI-native development environment, then go deeper on DeltaDB: a new approach to versioning software at the operation level, not just at the commit level. Nathan explains why so much important software work happens “between commits,” how agent conversations and code changes can become durable shared artifacts, and what it might mean for Git, collaboration, and the future of programming tools. Nathan previously helped build Atom at GitHub, and Zed describes DeltaDB as operation-level version control for human and AI collaboration.

Charity Majors is the co-founder and CTO of Honeycomb.io, where she pioneered the concept of modern observability for distributed systems. Before Honeycomb, she spent years at Parse (acquired by Facebook), Facebook, and Linden Lab building Second Life. She is the co-author of "Observability Engineering" and "Database Reliability Engineering" (O'Reilly). She writes at charity.wtf. Whatever she and Scott are planning, they are gonna observability the heck out of it.

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.
