Philippe Vanderstigel has launched several start-ups, but not all of them have been successful. Then, one summer, he landed on an idea for a budgeting app which his users loved. Suddenly, he had a new problem: how to maintain an app that people continued to use.

Docker has emerged as an extraordinarily popular way to safely and predictably deploy applications. But because of its rapid evolution, changing business targets, and technical composition, it can still be a bit daunting to understand when to use it versus other container runtimes, let alone the task of managing it via Kubernetes and other orchestrators. This episode takes a deeper look at the components of Docker, with a strong emphasis on developer productivity in smaller organizations, not massive enterprises. Bret Fisher is our guest, and as a certified Docker expert—a Captain, actually—his job (and passion) is to share his technical expertise.

Legacy code is everywhere. Software is also being modified, whether as a result of new requirements, new security issues to patch, or new hardware and operating systems to target. Whether you're working with code from three months or three years ago, the upgrade process doesn't need to be painful. Joe Leo is here to help us conquer our fears of fixing legacy systems. He's the CEO of Def Method, a software consultancy in New York. He'll teach us the effective strategies he's learned over his years of experience with upgrading plenty of code he didn't write. We're also going to give away a 40% discount code for Joe's new book on Ruby development!
