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.

Tight Coupling and its Unintended Consequences
As we transition from component architectures to service oriented architectures, the balance between natural, efficient asset reuse and independent, decoupled systems is a real battleground. Neal Ford recently posted some thoughts about high coupling and it's unintended consequences, and we revisit a great InfoQ interview with Jim Webber about tight coupling as it applies to service architectures.
