Joy talks with Vaughn Vernon about Domain-Driven Design. Vaughn shares his journey to DDD and the reasons behind his DDD books. They then go on to discuss strategic design, the broad brush strokes of DDD, what a model actually looks like and how to use bounded contexts to keep a system from becoming a big ball of mud. Vaughn then answers some questions about domain events and event sourcing, and makes a case for modelling uncertainty instead of fighting with concurrency.
Joy Clark talks with Gernot Starke about aim42, a method for systematically improving software. They discuss in detail the three phases of the process: Analyze, Evaluate, and Improve. Gernot shares his wisdom about how to carry out each phase using stories of his experiences in many different situations. In this way, listeners will get the big picture of how the whole process works: from visualizing all of the problems using sticky notes on the wall to specific strategies that can be used for improving the system.
Daniel Westheide, author of “The Neophyte’s guide to Scala” and Stefan Tilkov talk about some advanced Scala features and challenges, such as case classes and the problems they can create, algebraic data types, type classes and implicits, using the compiler for Prolog-like type level programming and programming with generic data structures.

The benefits of dynamic languages are also discussed, and clojure.spec is introduced as a way to gain the benefits of statically typed languages. Alex also talks about ways to structure Clojure code and gives a great list of tools and materials for getting started with Clojure.
Lucas Dohmen talks with Eberhard Wolff about microservices. Eberhard Wolff is a fellow at innoQ and wrote a book as well as a primer about microservices. He talks about what lead to microservices and the advantages, and disadvantages of as well as the preconditions for the architecture.
