In this week’s Design Podcast, I sit down with Jay Trimble, mission operations manager, ground data system manager, and resource prospector for the Lunar Rover Mission at NASA. We talk about applying Agile, adopting design thinking and user-centered design, and what he and his team rely on to design and build software for mission control.

Jonas Bonér, CTO of LightBend and creator Akka, discusses using Akka when developing distributed systems. He talks about the Actor Model, and how every Microservice needs to be viewed as a system to be successful. 

Why listen to this podcast:

 - Akka is JVM-based framework design for developing distributed systems leveraging the Actor Model - an approach for writing concurrent systems that treat actors as universal primitives and the most successful model with abstraction has been streaming
 - Circuit breakers in Akka are a backup and retry policy; they protect you by capturing failure data and allow you to roll back 
 - Every Microservice needs to be viewed as a system, it needs to have multiple parts that run on different machines in order to function and be fully resilient - thus is a Microsystem
 - Two different trends have emerged when it comes to hardware and environments: one is the trend toward Multi-core, the is a movement toward virtualized environments and the cloud
 - Saga pattern of managing long running transactions in a distributed system fits very well with messaging style architectures

Jonas Bonér on the Actor Model, Akka, Reactive Programming, Microservices and Distributed Systems

In this week’s Design Podcast, I sit down with Ben Yoskovitz, investor, entrepreneur, and former VP of product at VarageSale and at GoInstant. We talk about using metrics in product development and why anyone building anything new needs to have both hubris and intellectual honesty. Yoskovitz is co-author of Lean Analytics, and is teaching a two-day course on product strategy as part of the upcoming O'Reilly Design Conference.

This week, I sit down with Matt LeMay, product coach and consultant, and author of "Product Management in Practice." We talk about the four guiding principles of product management, what he has learned about himself as a product manager, and how to conduct meaningful research.

In this episode of the O’Reilly Programming Podcast, I talk with Ken Kousen, an author, instructor, and consultant who is presenting the live online training courses Functional Programming in Java 8 and Getting Started with Spring Boot in September and October. He is also the author of the newly published O’Reilly book Modern Java Recipes: Simple Solutions to Difficult Problems in Java 8 and 9.

Wes Reisz sits down and chats with Uncle Bob about The Clean Architecture, the origins of the Software Craftsperson Movement, Livable Code, and even ethics in software. Uncle Bob discusses his thoughts on how The Clean Architecture is affected by things like functional programming, services meshes, and microservices.

Why listen to this podcast:

* Michael Feathers wrote to Bob and said if you rearrange the order of the design principles, it spells SOLID.
* Software Craftsperson should be used when you talking about software craftsmanship in a gender-neutral way to steer clear of anything exclusionary.
* Clean Architecture is a way to develop software with low coupling and is independent of implementation details.
* Clean Architecture and Domain Driven Design (DDD) are compatible terms. You would find the ubiquitous language and bounded context of DDD at the innermost circles of a clean architecture.
* Services do not form an architecture. They form a deployment pattern that is a way of decoupling and therefore has no impact on the idea of clean architecture.
* There is room for “creature comforts” in a code base that makes for more livable, convenient code.
* “We have no ethics that are defined [in software].” If we don’t find a way to police it ourselves, governments will. We have to come up with a code of ethics.
