JUXT Cast

The frontier of AI is focused on the next model and the next capability. But the AI we already have is sufficient to sift through the decades of rules and regulations that have grown too tangled for any one person to hold in their head.

In this JUXTCast episode, JUXT CTO Henry Garner speaks with Mike Hsu, former US banking regulator and Acting Comptroller of the Currency, about what happens when code and policies drift from the context that gave them meaning. Both are written in good faith, for a particular moment, but the world moves on. What often remains is something we can't be sure still serves us, and don't dare to change. In software, we call this legacy code. Mike calls it policy sludge. And the remedies, it turns out, have a lot in common.

Along the way: how law and software are heading in opposite directions, what overlapping rules have to do with a sixty-year-old programming language, and why cleaning all of this up comes down to trust. Happy listening!

Most of the excitement around coding agents is about writing new code. But what about the code we already have?

In this JUXTCast episode, JUXT CTO Henry Garner speaks with Chris Ford (ThoughtWorks), author of the O'Reilly book Agentic Engineering at Scale, about pointing coding agents at large legacy systems.

Along the way: what after-dinner mints have to do with modernising them, why a good spec is never just markdown and whether AI will really make our software any better.

JUXT CTO Henry Garner will be presenting "Accelerating FINOS AI Governance Framework Adoption in Financial Services" at the upcoming FINOS conference on October 21st-22nd, 2025, in New York.

In this episode of the JUXTCast, we are joined by Malcolm Sparks (JUXT CTO), Henry Garner (Principal Engineer), Denis Lobanov (Senior Software Engineer), and Joe Littlejohn (Chief Delivery Officer) for an inside look at JUXT’s upcoming AI Radar. Initiated by Henry, the AI Radar is a new initiative designed to organise and share JUXT’s insights, advice, and recommendations on AI-related frameworks, tools, languages, and platforms. The team discusses the goals behind the project, key takeaways from their research so far, and how this evolving radar will support developers and decision-makers navigating the fast-moving AI landscape. Subscribe to our channel and stay tuned as the AI Radar will be available soon!

From settling into JUXT’s brand-new office to sharing insights from the XT25 Fintech Conference in London, the team discusses how the industry is evolving and how AI is shaping the future of software, finance, and developer tooling.

Whether you're curious about what’s next for JUXT or the broader fintech and AI landscape, this episode sets the tone for an exciting new chapter.

In this engaging episode of the JUXT Cast, Jeremy Taylor and Malcolm Sparks sit down with Ryan Robitaille, the founder of Rabbit, https://github.com/ryrobes/rvbbit. Ryan shares his unique journey—from working with Oracle systems as a young Solutions Engineer to becoming a creative force in the world of data visualization.

Ryan explores his experience building Rabbit, a tool designed to bridge the gap between proprietary BI tools and custom-built engineering solutions. Frustrated by the limitations of traditional tools like Tableau, Ryan envisioned a platform that offers the "best of both worlds": the simplicity of drag-and-drop dashboards with the power and flexibility of live coding and version control.

Key Takeaways from the Episode:

With fascinating anecdotes and deep technical insights, this episode sheds light on how data platforms can evolve to empower creativity, transparency, and collaboration.

This latest episode of the JUXTCast features Gene Kim, a Wall Street Journal bestselling author, celebrated researcher, and multiple award-winning Chief Technology Officer. Gene is widely recognized for his contributions to the DevOps movement and for co-authoring influential works such as The Phoenix Project and The DevOps Handbook. In this engaging discussion, Gene reflects on his career journey, from his time as the founder and CTO of Tripwire to his rediscovery of the joy of programming through Clojure. The episode explores key themes including high-performing technology organizations, the transformative role of AI in programming, and the strategic importance of modularity in systems design.

The conversation also offers unique insights into the evolving role of AI in augmenting developer productivity and creativity. Gene shares his hands-on experience with pair programming and discusses the intersection of REPL-based programming, economic principles in software design, and the future of junior developers in an AI-enhanced ecosystem.

In this episode, JUXT’s CEO Jon Pither, CTO Malcolm Sparks, and Head of Delivery Joe Littlejohn, are joined by guest Software Engineer Jake Howard to engage in a thoughtful discussion on the enduring static vs dynamic typing debate. While static typing has long been a staple in programming, the conversation leans toward the growing appeal of dynamic typing in modern software practices.

The team explores how dynamic typing allows for quicker iteration, greater flexibility, and better adaptation to shifting project demands. They also take time to weigh the structure and reliability that static typing provides, making for a balanced look at both approaches.

Our guest is Niall Murphy, CEO of Stanza - a company founded by a group of experienced SREs with a vision to provide the tools, coding platform, culture and community to give any organization industry-leading reliability. Niall previously worked at Google where he co-authored the book "Site Reliability Engineering: How Google Runs Production Systems" (2016).

In this podcast episode, we discussed Niall's extensive experience including his role within an important era for Google's infrastructure transformation beginning in the late 2000s, and the wider contemporary challenges in the SRE landscape.

Niall's reflections on operating distributed systems has lead him to the conclusion that there is still a profound missing gap in SRE tooling between discovering 'signals' and taking 'actions'.

The conversation begins by alluding to a couple of other recent podcasts we've recorded on distributed systems in 2024, one with Mark Burgess and the other with András Gerlits.
