This is the first episode (actually, episode zero) of software engineering radio. The episode does not contain real content, rather, Markus explains what the podcast is all about.

This is the second part of the remoting infrastructures discussion started in Episode 9. We take a look at how remoting infrastructures such as CORBA, .NET Remoting or Web Services work internally. This includes the low level details of the transport layer, marshalling, client proxies as well as interceptors and asynchronous communication. At the end, Michael will explain how all this relates to CORBA and Markus will map the concepts to .NET remoting. We don't have additional links in these show notes since all the relevant links had been posted for Episode 9 already.

In this Episode, we talk to Michael Stal, a Senior Principal Engineer at Siemens Corporate Technology, POSA 1 and 2 Co-Author and Editor of the german JavaSpetrum magazine. Since Michael's core focus is middlware, much of our discussion centered around that topic. Webservices and SOA, of course, have also been covered. Other topics include Java vs. .NET as well as Patterns.

In this third Episode on software architecture, Michael and Markus talk about the basic tools that an architect uses when architecting systems. These tools include things like separation, abstraction, compression and sharing. We also relate these tools to the quality attributes we introduced in previous archtecture episodes.

This episode is an interview with Werner Vogels, the CTO of amazon.com. We first talked about what scalability is, and which aspects there are to scalability. We then took a brief look at the technologies used at amazon, specifically, the middleware systems and the issue of vendor lock-in. Web services, and the role of SOA was the next topic. Then we covered what a service actually is add Werner explained the term "pizza teams". Testing and Deployment was the next topic followed by a look at architectural characteristics of scalable systems, the value of simplicity and the CAP theorem. We concluded the discussion with a brief look at the future of distributed systems

This is another episode where we mainly announce topics related to the podcast itself.

This episode features Scrum, a very popular Agile software development framework. We interview Roman Pichler, a Certified ScrumMaster Trainer and independent consultant. Roman explains the principles behind Scrum, its roles and its key practices. He also answers FAQs. This episode continues our track on software development processes discussing an additional Agile method. Roman is currently writing a book on Scrum in German that provides more in-depth information of the topics discussed in the podcast. The book will be available in autumn 2007 published by d.punkt (Heidelberg, Germany).

In this episode we talk with Gerard Meszaros about problems and challenges doing unit testing in real-world projects. Starting from a short discussion about the importance of automated unit testing we spend most of this episode to talk about every day problems doing unit testing and how those problems can be solved. Based on this book on xunit testing patterns, Gerard talks about his experiences with unit test smells as an analogy to code smells. He describes an impressive set of unit testing patterns to overcome those difficult testing situations and illustrates them with nice examples everybody doing unit testing will feel familiar with.

This episode is about OSGi, the dynamic module system for Java. Our guests are Peter Kriens (OSGI's Technical Director) and BJ Hargrave (OSGI's CTO). We'll discuss what OSGi is all about and why and in which contexts it is useful. Additionally we are having a look at the different layers of OSGI and where and how they are used. Other questions discussed are: What means dynamicity in an OSGI environment? Where is OSGI used? What’s the future of OSGI? How does OSGI interact with existing middleware solutions? How can I run several versions of the same JAR at the same time? Where are OSGI’s problems?

In this episode Charles Krueger, a well-known member of the product line engineering community, talks about his long term experiences in the field. Charles is also the founder and CEO of a company that provides tooling for variability management and product derivation. Besides some clarifications on terms like product line architecture and reference architecture, you also learn what kind of preconditions need to exist before product line engineering can be applied successfully.

In this episode we're talking to Hans-Joachim Popp, CIO at DLR about software in space. We start out by reviewing some well-known accidents of unmanned space flight that were caused by software faults and use this as a motivation to discuss how to avoid these in the future. We discuss culture, process, techniques and tools that DLR uses to create high-quality software for use in unmanned space systems.

In this episode we're talking to Andreas Zeller. about debugging. We started the discussion with an explanation of what debugging and how it works in principle. We then briefly discussed the relationship between debugging and testing. Next was the importance of the scientific method for debugging. We then looked as debugging as a search problem, leading to a discussion about delta debugging, the main topic of this discussion. We concluded the discussion by looking at the practical usability of delta debugging and the relationship to other means of automatically finding problems in software.

In this espisode we take a closer look at relational database systems and the concepts behind them. We start by discussing the relational paradigm, its concepts and ramifications, and go on to architectural aspects.

In this episode we're talking to Jens Coldewey about his experiences in 10 years of introducing agile techniques to project teams. We discuss real-world examples and the lessons learned and strategies derived from them.

In this episode we talk with Klaus Marquardt about building systems out of plugins. After briefly introducing the concept of a plugin in contrast to modules and related software engineering concepts, we discuss different views on plugins and different ways of working with plugins for developing software. We are looking at plugins for embedded systems as well as large business systems, at how plugins change the working mode and team organization, and discuss the possibilities of why and when to use plugins for implementing software systems.

In this episode we're talking to Linda Rising about retrospectives. We start by defining what a retrospective is and discuss some of the logistics of making it work for software projects. We then look at the different phases of a retrospective. The main part then is a discussion about some of the practices or games that are used to facilitate the retrospective. We conclude the retrospective discussion with destroying some of the prejudices against it and the relationship to process improvement and CMM. At the end of the interview we talk a little about Linda's current interest: how does the brain work?

This episode is a systematic introduction to Aspect Oriented Programming (in contrast to the interview with Gregor Kiczales). We discuss the fundamentals of AOP, define many of the relevant terms and also look at how and where AOP is used in practice, as well as at some current research trends.

This episode is a discussion with Andrew Watson, Technical Director of the Object Management Group. The episode is structured into five parts. We start with the history of the OMG and its early work. Then we look at the set of standards it has been (or is currently) working on. Next is a discussion of the standardization process used by the OMG, including the much-debated topic of compliance testing. We then look at OMG's relationship to other standards bodies (W3C, OASIS). Finally Andrew and I briefly discuss our common passion, gliding :-)

We start our discussion with a brief look at what Haskell is and how a pure functional language is different from non-pure languages. We then look at the basic building blocks and the philosophy of the language, discussing concepts such as the lambda calculus, closures, currying, immutability, lazy evaluation, memoization, and the role of data types in functional languages. A significant part of the discussion is then spent on the management of side effects in a pure language - in other words, the importance of monads. We conclude the episode with a look at Haskell's importance and community today.
