Kevlin shares his thoughts on the software craftmanship movement and states his opinion on the discussion whether our profession is a form of engineering or not. In some parts of this discussion we refer to the Hot-or-Not presentation that Kevlin gave the night before the interview at Sioux, the Netherlands. You can find the slides of this presentation here.

The interview was recorded at the hotel 'la Sonnerie' in Son & Breugel. We would like to thank the hotel for their hospitality by providing the chapel as a recording room for the podcast.

• Kevlin (co) authored two books of the Pattern-Oriented Software Architecture serie: volume 4 is a worked example of patterns for distributed computing and the 5th volume is a book on the concepts of patterns.
• In the podcast Kevlin refers to a famous quote of Jason Gorman: 'Software craftsmanship's not the "next big thing". It's an attempt to articulate what the "thing" always was'.
• Scrum can be seen as a 'Nomic' game, which is a game in which changing the rules is one of the rules.
• In a presentation called 'With Economy and Elegance - Software Engineering reclaimed' (slides here) Kevlin explains that Software Engineering is a form of engineering and a craft - following his claim there are no contradictions.
• Glenn Vandenburg explains what is wrong with the way Software Engineering is taught at universities in the presentation called 'Real Software Engineering' (video here).
• Software development is all about passion and fun. An example of passion is the Tenet of Professionalism from Uncle Bob: 'Work 40 hours for your employer and another 20 hours improving yourself'.
• A great example of fun and playfulness in our industry is 'the Globe', a piece of Ruby software which rotates itself.
• Another way to look at your code is with a tag cloud of all words used in a piece of software. This idea was proposed by Phillip Calçado.

The basic premise of the book is that we need to move beyond Continoous Integration and occasional delivery and work towards practices that allow for the creation and deployment of final deliverables on all environments on every check-in. Jez and Dave explain the concepts behind the deployment pipeline and we discuss the practices and policies that come into play from the moment of check-in to updating the live version of software.

We talk about various strategies and patterns for testing, building and releasing software, and how these fit in with agile and lean software development.

We talk about Lean principles in the context of manufacturing and product development, and how these apply to software development. Don explains how variability is important for innovation, and how reduction in batch sizes and queues will improve flow. We discuss the economic model and the focus on quality vs utility. Don also discusses agile software methods like Scrum and Kanban and how they use some of the principles of product development.

Don was in the Netherlands for the Lean & Kanban 2011 Benelux conference. His keynote 'Is It Time to Rethink Deming' can be viewed here courtesy of @agileminds.

• The roots of the 'Londen-style' of Test-Driven Development can be traced back to the eXtreme Tuesday Club (XTC). A weekly London (pub) meeting that started more than 10 years ago.
• On his blog Nat visualizes different kinds of tests that drive the design of a software system.
• In the podcast we discuss the blogpost 'Whose domain is it anyway?' of Dan North.
• Nat completed his PhD thesis in 2000: 'Component Interaction in Distributed Systems'. A lot of his thoughts on object-orientation and messaging between objects and peers that is described in the book, can be traced back to his early research.
• In order to improve the testability of your software, Steve and Nat propose to apply the Ports and adapter architecture from Alistair Cockburn. You can read more on this subject on the wiki of Alistair.
• Use Hamcrest Matchers to improve the readability of your tests: learn more from this tutorial.
• While the use of Dependency Injection is widely spread in the software engineering community, Nat considers applying this style harmful. On his blog you can read more of his thoughts on this subject.
• In 2004 Steven and Nat published the article 'Mock Roles, not Objects' in which they introduces jMock.
• MultithreadedTC: a framework that can be used to test concurrent Java applications.
