In this Episode, Eberhard and Markus provide an introduction to Model-Driven Software Development. Since the discussion turned out to be too long, we separated things into two episodes, thus Episode 6 will be the second part of this discussion. In this first part we disucsss core concepts of MDSD, the relationship to MDA, and hint at a couple of tools.

After discussing some of the more technical aspects of MDSD in the last episode, we take a look at other important topics in this one. This includes some tips on how to introduce MDSD into projects and how the development process has to be adapted for this to work, as well as a look at the return on investment for MDSD. The relationship of MDSD and Agile software development is also discussed. Finally, we take a look at offshoring in the context of MDSD.

A very important area for Java are Enterprise Systems. With the advent of new technologies like Ruby on Rails, Java EE 5 or EJB 3 the landscape for Enterprise Systems appears to be changing a lot at the moment. In this episode Markus talks with Eberhard about what Enterprise Java actually is, why and where it is used. Based on that they discuss what the future might look like and how to make Enterprise Java shine in the future.

This show takes a behind-the-scenes look at compilers and their inner workings, using the Gnu compiler collection (GCC) as an example. Arno interview Morgan Deters, covering all steps from the parsing of different programming languages to machine independenet optimizations and generating processor specific binary code.

In this Episode we're discussing patterns for small memory software with the authors of the like-named book Charles Weir and James Noble. We look at various aspects of the small memory problem: How can you manage memory use across a whole system? What can you do when you have run out of primary storage? How can you fit a quart of data into a pint pot of memory? How can you reduce the memory needed for your data? How do you allocate memory to store your data structures? Answers to all those questions are provided in this Episode, and of course in their book.

In this episode Eberhard Wolff speaks with Jürgen Höller, the co-found of the Spring framework. Spring is a tremendously successful Java framework so they discuss the design of large frameworks and the issues that arise in the evolution. Jürgen explains the management of dependencies in the framework, how to structure such a framework, how to offer compatibility for the existing user base while evolving the framework and the role of metrics during development.

In this episode, Michael and Markus talk about software components. We first looked at a couple of attempts at defining what a component is. We then provided our own definition that will be used in the rest of the episode. We then looked at the promises of component-based development: why are components useful? We then discussed some of the typical metadata components should specify to make them useful. We discussed to some extent typical variations in component models. The next topic was the separation of concerns between the component functionality and functionality provided by the component's execution environment (aka. container). We then compared components with other (more or less) related technologies such as OO and SOA. We concluded the episode with the notion of architecture as language, where you use a formal DSL to describe a system's architecture. Components are the basic building block for this approach.

This episode is the long-awaited (and much requested) interview with Krzysztof Czarnecki, the author, together with Ulrich Eisenecker, of the book Generative Programming. In the interview we discussed the state of generative programming today and related it to model-driven development and DSLs. We then talked a little bit about product lines in general. We then discussed his current field of research, which currently focusses on framework-specific modeling languages and non-trivial roundtrip engineering.

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 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.

This is the first part of a two part topic on roles in software engineering. Michael and Markus discuss role definitions in an corporate environment. For several typical roles we give hints on the expected skills, knowledge, and mindset. In this episode we discuss the roles junior developer, senior developer, and software architect.

This is the second part of the two part topic on roles in software engineering. Michael and Markus discuss role definitions in a corporate environment. For several typical roles we give hints on the expected skills, knowledge, and mindset. In this episode we discuss the roles technical lead, technologist, requirements engineer, product manager, and project manager.

In this episode we talk to Christof Ebert about requirements engineering. As the name "engineering" suggests, we need to be systematic when working and managing requirements. Christof will structure RE into several activities, namely elicitation (identifying the relevant requirements), specification (clearly describing requirements), analysis (synthesizing a solution), verification and validation (achieving good requirements quality), comittment (allocating requirements to a project, product release or iteration), and management (keeping track of the implementation status of requirements). In this episode we discuss these activities and highlight lots of practical guidance.

In this episode we discuss Microsoft's OSLO platform with Doug Purdy and Don Box. We briefly discuss what OSLO is in general and then look at the various components of OSLO. We also look at how OSLO fits in with the general Microsoft strategy and how it compares to other DSL/Model-driven approaches. We then look at language modularization and composition and discuss the similarities with XML and Smalltalk. Finally, we discuss possible integrations of OSLO with other MD* approaches and technologies.

In this episode Michael interviews one of our regular listeners: Petri Ahonen. Petri introduces Software Configuration Management by defining key terms and describing relevant concepts.

In this episode, Dirk talks with David Frankel, resident Metamodeller and MDA expert at SAP Labs LLC, SAP's subsidiary in the Silicon Valley. Dave's extensive experience provides a big picture, from the early days of CORBA all the way to current issues that are bugging most enterprise architects' work with MDA.

In this episode, Allan shares his insights about how learning is a necessary part of software development. He covers the personal as well as the team and the organizational level and offers practical advice.

Michael and Markus discuss what makes a good R&D manager and how to potentially become an R&D manager. You will learn what some of the essential skills are, what the challenges are, and what the 'mission/vision/strategy thing' is actually good for.

Dave explains why reading source code is at least as important a skill as writing source code. He shares approaches for how to get to grips with unknown and undocumented source code even if it is non-trivial in size. He finishes with advice for how to get started reading code.

Michael discusses with his guest Chuck Connell the differences between software engineering and computer science. What makes software engineering so unpredictable, with so few formal results? And how can we advance the field of software engineering without these results?

This episode is a conversation with "Uncle Bob" Bob Martin about agile software development and software craftsmanship specifically. We talk about the history of the term, the reasons for coming up with it some of the practices and the relationship to other agile approaches.
