As we close the chapter on 2025 and celebrate our second year of 'Rust in Production', it's time to reflect on the highlights of the 17 episodes since our last holiday special. We looked at Rust from all angles, from cloud infrastructure to embedded systems, and from robotics to satellite technology. One thing that all these stories have in common is the passion and dedication of the Rust community to build faster, safer, and more reliable software. In this special episode, we look back at some of the memorable moments from the past year and celebrate Rust's achievements. This goes beyond the case studies we've covered; it's about the Rust community as a whole and the state of the Rust ecosystem at the end of 2025.
Bringing Rust into the Linux kernel is one of the most ambitious modernization efforts in open source history. The Linux kernel, with its decades of C code and deeply ingrained development practices, is now opening its doors to a memory-safe language. It's the first time in over 30 years that a new programming language has been officially adopted for kernel development. But the journey is far from straightforward. In this episode, we speak with Danilo Krummrich, Linux kernel maintainer and Rust for Linux core team member, about the groundbreaking work of integrating Rust into the Linux kernel. Among other things, we talk about the Nova GPU driver, a Rust-based successor to Nouveau for NVIDIA graphics cards, and discuss the technical challenges and cultural shifts required for large-scale Rust adoption in the kernel as well as the future of the Rust4Linux project.

What does it take to rewrite the foundational components of one of the world's most popular Linux distributions? Ubuntu serves over 12 million daily desktop users alone, and the systems that power it, from sudo to core utilities, have been running for decades with what Jon Seager, VP of Engineering for Ubuntu at Canonical, calls "shaky underpinnings." In this episode, we talk to Jon about the bold decision to "oxidize" Ubuntu's foundation. We explore why they're rewriting critical components like sudo in Rust, how they're managing the immense risk of changing software that millions depend on daily, and what it means to modernize a 20-year-old operating system without breaking the internet.
Building a new programming language from scratch is a monumental undertaking. In this episode, we talk to Richard Feldman, creator of the Roc programming language, about building a functional language that is fast, friendly, and functional. We discuss why the Roc team moved away from using Rust as a host language and instead is in the process of migrating to Zig. What was the decision-making process like? What can Rust learn this decision? And how does Zig compare to Rust for this kind of systems programming work?
I have a hobby. Whenever I see the comment // this should never happen in code, I try to find out the exact conditions under which it could happen. And in 90% of cases, I find a way to do just that. More often than not, the developer just h...

How do you build a system that handles 90 million requests per second? That's the scale that Cloudflare operates at, processing roughly 25% of all internet traffic through their global network of 330+ edge locations. In this episode, we talk to Kevin Guthrie and Edward Wang from Cloudflare about Pingora, their open-source Rust-based proxy that replaced nginx across their entire infrastructure. We'll find out why they chose Rust for mission-critical systems handling such massive scale, the technical challenges of replacing battle-tested infrastructure, and the lessons learned from "oxidizing" one of the internet's largest networks.
Building autonomous robots that operate safely in the real world is one of the most challenging engineering problems today. When those robots carry sharp blades and work around people, the margin for error is razor-thin. In this episode, we talk to Andrew Tinka from Scythe Robotics about how they use Rust to build autonomous electric mowers for commercial landscaping. We discuss the unique challenges of robotics software, why Rust is an ideal choice for cutting-edge safety-critical systems, and what it takes to keep autonomous machines running smoothly in the field.

Are you one of over 240 million subscribers of Amazon's Prime Video service? If so, you might be surprised to learn that much of the infrastructure behind Prime Video is built using Rust. They use a single codebase for media players, game consoles, and tablets. In this episode, we sit down with Alexandru Ene, a Principal Engineer at Amazon, to discuss how Rust is used at Prime Video, the challenges they face in building a global streaming service, and the benefits of using Rust for their systems.
The phone buzzes at 3 AM. You roll out of bed, open your laptop, and see this in the logs: thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: Error("data did not match any variant of untagged enum Custom...
It’s time for another recap including our highlights of Season 4. We’ve been at this for a while now (four seasons, and 32 episodes to be exact). We had guests from a wide range of industries: from Microsoft to Astral, and from password managers to satellite systems. This time, it’s all about using Rust for foundational software, which is software that is critical to a team or even an entire organization. Rust is a great fit for this type of software! We would like to thank the guests for their time and insights. We would also like to thank you, the listener for your support and feedback. Hosting and producing a podcast is a lot of work, but it’s worth it when we hear from you. Here’s to another great season!

As a kid, I was always fascinated by space tech. That fascination has only grown as I've learned more about the engineering challenges involved in space exploration. In this episode, we talk to Vegard Sandengen, a Rust engineer at KSAT, a company that provides ground station services for satellites. They use Rust to manage the data flow from hundreds of satellites, ensuring that data is received, processed, and stored efficiently. This data is then made available to customers around the world, enabling them to make informed decisions based on real-time satellite data. We dive deep into the technical challenges of building reliable, high-performance systems that operate 24/7 to capture and process satellite data. Vegard shares insights into why Rust was chosen for these mission-critical systems, how they handle the massive scale of data processing, and the unique reliability requirements when dealing with space-based infrastructure. From ground station automation to data pipeline optimization, this conversation explores how modern systems programming languages are enabling the next generation of space technology infrastructure.

Handling secrets is extremely hard. You have to keep them safe (obviously), while at the same time you need to integrate with a ton of different systems and always provide a great user-experience, because otherwise people will just find a way around your system. When talking to peers, a lot of people mention 1Password as a company that nailed this balance.
Recently I was in need of a simple job queue for a Rust project. I already had Postgres in place and wondered if I could reuse it for this purpose. I found PGMQ by Tembo. PGMQ a simple job queue written in Rust that uses Postgres as a backe...
In today's episode, I talk to Adam Hendel, the founding engineer of Tembo, about their project, PGMQ, and how it came to be. We discuss the design decisions behind job queues, interfacing from Rust to Postgres, and the engineering decisions that went into building the extension.
"Unpopular opinion: error handling in Rust is actually fantastic. Once you know the right patterns, which regrettably are NOT always obvious 😂"
