Mainframe modernization is hard: there's a huge amount of complexity that needs to be understood before it can be effectively addressed. Generative AI, however, can be a particularly powerful tool for understanding mainframe legacy codebases, something we've been exploring with Mechanical Orchard while working together on its Imogen modernization platform.

In this episode of the Technology Podcast, hosts Ken Mugrage and Alexey Boas are joined by Thoughtworks CTO Rachel Laycock and Mechanical Orchard CEO and Founder Rob Mee to discuss the partnership between the two organizations. They discuss how the collaboration began, the challenges of leveraging generative AI tools for such risky projects and what the wider implications are for AI in software engineering. Listen for a fresh perspective on both legacy modernization and generative AI.

You might think you know software engineering, but what are the really fundamental elements? What are the concepts, ideas and practices that are completely essential? What makes software engineering what it is?

Thoughtworker Nate Schutta and Dan Vega are attempting to address those questions in their upcoming book with O'Reilly, The Fundamentals of Software Engineering. Covering topics ranging from reading code through to the importance of learning to learn, it promises to offer a fresh insight into the skills and knowledge needed to be a successful software engineer.

In this episode of the Thoughtworks Technology Podcast, Nate and Dan join hosts Neal Ford and Ken Mugrage to discuss the book and to dive into what really are the fundamental elements of software engineering. Listen for a fresh perspective on the discipline and a deep dive that shows it's about far more than just writing code.

Thoughtworks Technology Radar Vol.32 was published at the start of April 2025. Featuring 105 blips, it offered a timely snapshot of what's interesting and important in the industry. Through the process of putting it together, we also identify a collection of key themes that speak to the things that shaped our conversations.

This time, there were four: supervised agents in coding assistants, evolving observability, the R in RAG and taming the data frontier. We think they point to some of the key challenges and issues that industry as a whole is currently grappling with.

To dig deeper and explore what they tell us about software in 2025, regular host Neal Ford takes the guest seat alongside Birgitta Böckeler to talk to Lilly Ryan and Prem Chandrasekaran. They explain how the themes are identified and discuss their wider implications.
