Rust in Production

Version control is a critical part of any modern software project and git is the most popular tool for the job. But it can be complex and confusing, especially for beginners.
The team behind GitButler believes there is a better way.

They are building a modern Git client that streamlines the process of managing branches, backing up your work, and more. We hear from co-founders Scott Chacon and Kiril Videlov about how they're making Git easier for everyone -- all without sacrificing the power and flexibility that makes Git so popular in the first place.
About GitButler
Git Branching, Refined — that's the promise of GitButler. GitButler is a Git client that helps you manage your Git branches more effectively. GitButler records and backups up your work, helps with your code and much more. Their focus is everything after writing code in your editor and before sharing it on GitHub. The client is written in Rust, by the way.
About Scott Chacon
Scott Chacon is a co-founder of GitButler. Previously, he was a co-founder at GitHub. Scott is the author of the famous Pro Git book (which taught me Git, thank you very much) and an investor in a number of companies through his incubator, SCNE. He somehow also found the time to get a B2 in German.
About Kiril Videlov
Kiril Videlov is a co-founder and CTO of GitButler. He has a background in software engineering, especially in the fields of fintech and code analysis. He is a YC alum and has a Master's degree in Computer Science.

What's even cooler than writing your own text editor or your own operating system? Building your own hardware from scratch with all the software written in Rust -- including firmware, the scheduler, and the hypervisor. Oxide Computer Company is one of the most admired companies in the Rust community. They are building "servers as they should be" with a focus on security and performance to serve the needs of modern on-premise data centers.

In this episode, I talk to Steve Klabnik, a software engineer at Oxide and renowned Rustacean, about the advantages of building hardware and software in tandem, the benefits of using Rust for systems programming, and the state of the Rust ecosystem.
About Oxide Computer Company
Founded by industry giants Bryan Cantrill, Jessie Frazelle, and Steve Tuck, Oxide Computer Company is a beloved name in the Rust community. They took on the daunting task of rethinking how servers are built -- starting all the way from the hardware and boot process (and no, there is no BIOS). Their 'On The Metal' podcast is a treasure trove of systems programming stories and proudly served as a role model for 'Rust in Production.'

About Steve Klabnik

In the Rust community, Steve does not need any introduction. He is a prolific writer, speaker, and software engineer who has contributed to the Rust ecosystem in many ways -- including writing the first version of the official Rust book. If you sent a tweet about Rust in the early days, chances are Steve was the one who replied. Previously, he worked at Mozilla and was a member of the Rust and Ruby core teams.

Many devs dream of one day writing their own operating system. Ideally in their favorite language: Rust. For many of us, this dream remains just that: a dream.

Jeremy Soller from System76, however, didn't just contribute kernel code for Pop!_OS, but also started his own operating system, RedoxOS, which is completely written in Rust. One might get the impression that he likes to tinker with low-level code!
In this episode of Rust in Production, Jeremy talks about his journey. From getting hired as a kernel developer at Denver-based company System76 after looking at the job ad for 1 month and finally applying, to being the maintainer of not one but two operating systems, additional system tools, and the Rust-based Cosmic desktop. We'll talk about why it's hard to write correct C code even for exceptional developers like Jeremy and why Rust is so great for refactoring and sharing code across different levels of abstraction.
About System76

From hardware all the way up to the UI, System76 pushes hard for vertical integration. The company has a strong following amongst Linux enthusiasts and is a big advocate for Rust. They use it across the stack for most (all?) of their major projects. Instead of GNOME or KDE, the Denver-based company even built their own user interface in Rust, called COSMIC.
About Jeremy Soller

Jeremy is a hardware and kernel hacker who has an intricate understanding of low-level computing. With Redox OS, an operating system fully written in Rust, he was one of the first developers who pushed the boundaries of what was possible with the still young language. The first release of Redox was in April 2015 when Rust hadn't even reached 1.0. By all means, Jeremy is a pioneer in the Rust community, an expert in low-level programming, and an advocate for robust, reliable systems programming.

Rust can run everywhere, and by everywhere, we don't just mean on all operating systems, but also in all kinds of harsh environments: from the depths of the ocean to the vastness of space. Today we talk to a company that is using Rust to conquer the air. Fusion Engineering is building drone control systems for the next generation of drones.

Jakub Valtar walks us through how Fusion Engineering came to use Rust as the foundation of their company. He explains why Rust is the safest choice for building drone control systems and what it takes to get into drone development.
About Fusion Engineering
Fusion Engineering identified a critical gap in the industry: while drone hardware has advanced rapidly, software development has lagged behind.Their approach is ambitious - developing drone control systems from the ground up, with a strong focus on safety. It's about making drones fly reliably in complex environments.Their flight controller is designed to meet the most stringent EU regulations, potentially allowing drones to operate safely in urban areas and withstand harsh conditions offshore.
About Jakub Valtar
Jakub Valtar is a game engine developer turned drone software engineer. He feels comfortable in performance-critical environments and loves the intersection between art and technology. He joined Fusion Engineering to work on control systems for the next generation of drones.

It has become a trope by now: "Cars are computers on wheels." In modern cars, not only the infotainment system but also the engine, brakes, and steering wheel are controlled by software. Better make sure that software is safe.Alexandru Radovici is a Software Engineer at OxidOS, a company that builds a secure, open-source operating system for cars built on Rust and Tock. We talk about the challenges of certifying Rust code for the automotive industry and the new possibilities with Rust-based car software.
About OxidOS
OxidOS is a Rust-based secure ecosystem for safety critical automotive ECUs. Their solution consists of a Rust-based Secure Operating System and DevTools for medium-size microcontrollers inside automotive ECUs, designed for safety-critical applications. The OxidOS ecosystem provides significant security and safety enhancements while reducing development and certification time by half for automotive ECU software development projects. This is achieved through the usage of Rust that brings benefits such as memory and thread safety enforced at compile time. The OxidOS architecture runs memory sandboxed applications, which have cryptographic credentials and are digitally signed.

About Alexandru Radovici
Alexandru Radovici is an Associate Professor at the Politehnica University in Bucharest, Romania, where he has been using Rust to teach for a few years. Alexandru is also one of the maintainers of the Tock embedded operating system, written fully in Rust.
