This episode is a conversation with Erich Gamma. We covered the four things he is known for in chronological order. We started with design patterns and the Gang-of-Four book of which he is the lead author. We then looked at JUnit, the testing framework he coauthored with Kent Beck and how it introduced unit testing to the masses. The next topic is obviously Eclipse, where Erich and his lab in Zürich is responsible for the Java Development Tooling. We also briefly discussed The Eclipse Way, the (obviously) successful process the Eclipse team uses for developing Eclipse itself. Finally, we're looking at Erich's current endeavour, the Jazz project. Jazz is a technology for collaborative software development.

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 we're talking with Dick Gabriel on Lisp. We started by looking at artificial intelligence as the historic context of Lisp, the goals AI tried to reach, and how Lisp was supposed to help reach those. We then discussed the language itself, starting with the Data As Program / Program As Data concept that is a foundation for Lisp. Then we discussed adding a meta-circular interpreter, programming as language development, and the blurred boundary between language and frameworks (because everything uses the same syntax). We then talked about Lisp's type system and the importance of macros to extend the language. The next section concerned CLOS, the Common Lisp Object System and its important concepts: generic functions, multimethods, mixins, and method combination. We also briefly looked at the meta-object protocol but agreed this is a topic for a separate episode. After a discussion about the various dialects of Lisp and Scheme, we concluded the Lisp discussion by explaining why Lisp did not really catch on ("AI Winter") and Lisp's role in today's industry. We ended the episode with a couple of details about Dick's other life as a poet and his Poem a Day effort. Make sure you listen till the end, where we have added a song about Lisp (courtesy of Prometheus Music.)

In this episode we talk to Galen Hunt about the Singularity research OS. Galen is the head of Microsoft's OS Research Group and, together with a team of about 30 other researches, has built Singularity. We started our discussion by covering the basics of Singularity: why it was designed, what the goals of the project are as well as some of the architectural foundations of Singularity: software isolated processes, contract-based channels and manifest-based programs. In this context we also looked at the role of the Spec# and Sing# programming languages and the role of static analysis tools to statically verify important properties of a singularity application. We then looked a little bit more closely at the role of the kernel and how it is different from kernels in traditional OSes. In a second part of the discussion we looked at some of the experiments the group did based on the OS. These include compile-time reflection, using hardware protection domains, heterogenerous multiprocessing as well as the typed assembly language We closed the conversation with a look at some of the performance characteristics of Singularity, compatibility with traditional operating systems and a brief look at how the findings from Singularity influence product development at Microsoft.

In this Episode, Arno talks with Oliver Jucknath about the art of writing computer games. A lot of myth is attached to this area of computing, and while a game technically is just another program, it is written in a different context than typical business applications. This is true at the code level, where aggressive optimization is a focus throughout development. It also applies at the team level, where collaboration between specialists is pronounced. And the business context is different as well, which in turn influences the development effort as a whole.

This episode is a discussion with Michael Nygard about his book "Release It" which covers aspects of software architecture you often don't think of initially when starting to build a system. Some of the points we discussed were capacity planning, recovery as well as making the system suitable for operation in a data center.

This episode is a conversation with Gilad Bracha about Newspeak, type systems in general and optional/pluggable types in particular.

This time we have John Wiegand on the mic for an episode on architectures and agile software development. We talk about the role of architectures in an agile world and why architectures change and need to change over time. We discuss the characteristics of those living architectures, using the Eclipse and the Jazz projects as examples, and the surrounding development methods for such environments.

We discuss characteristics and performance properties of modern games and outline the challenges for software development.

Michael Nygard of “Release It!” fame talks with Stefan Tilkov about his experience using the Clojure programming language. Topics include the tool chain and development process, the Clojure learning curve, and on-boarding new developers. Michael explains the similarities and differences compared to typical OO languages when implementing domain logic, and uses both game development and typical web development projects as examples. Finally, the two discuss how well Clojure can be used in the face of long-running projects, and some typical obstacles and strategies for introducing it to real-world scenarios.

Morgan Wilde talks with SE Radio’s Jeff Meyerson about the LLVM compiler toolchain. They begin with a discussion of how a compiler works and how compiled code executes against different processor architectures. Using the JVM as a model for interoperability, they move on to how LLVM is a system that optimizes an intermediate representation (IR), which is similar to the Java bytecode: every programming language that compiles down to IR can leverage the same optimizations of that IR. The conversation concludes with a discussion of applications of LLVM and the future of the ecosystem.

Asaf Yigal talks with SE Radio’s Edaena Salinas about machine learning in log analysis. The discussion starts with an overview of the structure of logs and what information they can contain.
