The term 'vibe coding' — which first appeared in a post on X by Andrej Karpathy in early February 2025 — has set the software development world abuzz: everyone seems to have their own take on what it is, how it's done and whether it's a bold new chapter in the history of programming or an insult to anyone that's ever written a line of code.

Clearly, then, we need to talk about vibe coding — and that's precisely what we do on this episode of the Technology Podcast. Featuring Thoughtworkers Birgitta Böckeler (AI for Software Delivery Lead) and Lilly Ryan (Cybersecurity Principal), who join hosts Neal Ford and Prem Chandrasekaran, we dive into the different understandings and applications of the concept, and discuss what happens when a meme collides with reality.

Nearly ten years after the first edition of Infrastructure as Code was published by O'Reilly, Kief Morris is publishing a third edition of the book. But why a new edition now? What's changed in technology and business over the last decade?

Quite a lot, as it happens. To talk about what's new — both in the infrastructure world and in the book itself — Kief Morris joins host Ken Mugrage on the Technology Podcast. They discuss each edition and what's new in this one, and dive into the infrastructure challenges and issues that need to be tackled in 2025, from tooling and deployment to maintenance and infrastructure evolution.

AI is inherently dynamic: that's true in terms of the field itself, and at a much lower level too — models are trained on new data and algorithms adapt and change to new circumstances and information. That's part of its power and what makes it so exciting, but from a business and organizational perspective, that can make governance and measurement exceptionally difficult. How can we know that our AI is optimized for the right thing? How can we be sure it's oriented towards what we want it to be?

This is where the concept of fitness functions can help. Broadly speaking, fitness functions are ways of measuring the extent to which a given solution is fulfilling its goals — so, in the context of AI, they can help teams ensure that AI systems are serving their intended purpose.

In this episode of the Technology Podcast, Rebecca Parsons and Neal Ford — authors (alongside Pat Kua and Pramod Sadalage) of Building Evolutionary Architectures, the book which brought fitness functions into the software architecture space — join host Ken Mugrage to explore how the fitness function concept can help us better manage the dynamism of AI and, in doing so, overcome the challenge of bringing such systems into production.
