Communicating with Business Using FIT and FitNesse
Although both FIT and FitNesse are used for performing integration and acceptance testing on agile projects, people have tried to use these for general-purpose testing, with mixed results. Others have suggested that FIT should be used for tests where communicating with the business, or with a customer, is of paramount importance. Naresh Jain and James Shore have shared their experiences.

Borrowing Functional APIs from F#
The Common Language Specification ensures that any conforming .NET language can access libraries created by any other language. This means imperative languages like VB and C# can call functional libraries created primarily for F#. In fact, many can be converted directly into C# code.

Reducing Server Load and Network Traffic in REST/Ajax Architectures
A short article on developerWorks shows us how to reduce network traffic and server processing for Ajax/REST architectures, but the real jewel here is the way they effectively use the HTTP 304 status code instead of recommending more complicated solutions.

Test Driven Development or Test Driven Requirements?
Where does one start when practicing test driven development? With the requirements or with the design? Or, put another way, top-down or bottom-up? When one starts to write a test first, without any code, what does that test represent? Both approaches are practiced in the Agile community, but there is little consensus on which provides more value.

Anatomy of Service Delivery Platforms
In this article, Fred Chong and his colleagues detail the architecture of modern Service Delivery Platforms and how they could be leveraged by Solution Vendors. They review their capabilities from security & identity, to metering & billing, on-boarding of application tenants & provisioning... and develop guiding principles for the evolution of this new type of infrastructure software.

Introducing Farseer - An Open Source Physics Engine for Silverlight and XNA
In the modern push for showier and more interactive interfaces, it is inevitable that real-time animation is asked for from time to time. When this animation involves objects on the screen bouncing off each-other or being affected by gravity, a physics engine is a must. The Farseer Physics Engine addresses this need. We interviewed Jeff Weber, designer of Farseer.

Qi4j introduces Composite Oriented Programming
"Classes are dead, long live interfaces" was declared by Rickard Oberg at Oredev this week where he announced Qi4j. Qi4j brings the new idea of Composite Oriented Programing, in which is no behaviour at all is put in a class, instead the class becomes a 'composite' of mixins and interfaces declared on the class via annotations.

Designing for flexibility and robustness: Asynchronous message model, OOP and Functional Programming
According to Pragmatic Programmers it is preferable in OOP to avoid design based on returning values. Michael Feathers argues that it may also be better to use the asynchronous message model that might be instrumental for improving adaptability and robustness. This maps well to the Erlang model though opposing some of the principles of pure functional programming.
