Episode 37: eXtreme Programming Pt.1

This is the first of two episodes where Arno and Alex discuss eXtreme Programming in se-radio’s development process track. eXtreme Programming (XP) revolutionized the way of thinking about software development methodologies and helped to make the agile movement popular. In this episode they discuss the very basics of XP, its value system, principles and the basic practices used in an XP project. The second episode will continue the introduction adding the missing practices and how to introduce XP into projects.

Episode 33: Service Oriented Architecture, Pt.2b

This is the second snippet of the SOA 2 double-episode. Eberhard and Markus continue the discussion with the issue of service reuse and a couple of development process issues. We also look at the duality between infrastructure development and application development in the context of an SOA. We then discuss the great spaghetti misunderstanding :-). We conclude this episode with a look at how to integrate BPM into the conceptual SOA framework we’ve built up to now, and we’ll also briefly skim over a number of technologies related to SOA.

Note that this episode, as well as the last one, is based on a set of slides; these can be downloaded from here. This episode covers slides 39 through 74.

Episode 32: Service Oriented Architecture, Pt.2a

In this, as well as in the next episode Eberhard and Markus continue their discussion about SOA (the episode got too long, so we had to split it into two … SOA 2a and SOA 2b). In this episode, we talk about the various perspectives on SOA (CBD, EAI, BPM), about fundamental requirements towards an SOA, and we discuss the role of models in defining sustainable architectures. We also discuss how a programming model based on the described approach typically looks like. We then discuss a number of issues any large-scale SOA faces (and for which the SOA paradigm does not really provide an out-of-the-box solution: In this episode we discuss data type ownership and (weak) typing of data types.

Episode 29: Concurrency Pt.3

The third part of our concurrency series by Michael and Alexander discusses how to build highly scalable servers. The discussion focusses especially on event-driven servers. As possible solution patterns a reactor-based design is suggested along-side several patterns for multi-threading issues: Reader/Writers Locks, Thread Pools, and Leader/Followers.
