Maven-Reference, Validation and Geek-Videos
- I’ve stumbled over this Maven online book. It’s quite useful for everyone who’s maintaining Maven-builds.
- This post about “Magic” null argument testing describes how to implement an extremely elegant way to check arguments in C#. The check looks like this:

- Do you know co- and contravariance in programming-languages? Well how about co- and contravariance in physics? Have they something in common? Well on geeky series on channel9 Brian Beckman and Erik Meijer try to find out. In the first video Brian introduces co- and contravariance in physics. After that, Brian and Erik try together to find the similarities, Brian representing the physicist, Erik the programming-language guy. The first and second part are available, however the question is still no answered. Therefore a third video will be available later.
