Life without Stupid Objects, Episode 1

So, this is not, strictly speaking, the next post to the previous post. Along the road, I realized I was using a certain style in the little code I wanted to show, and that it wasn't the style most people use, and that it would be distracting to explain that style while trying to communicate a much more important concept. 

So this post is about persistence and a way of writing repositories. Or it is about avoiding objects with no methods and mappers between stupid objects. Or it is about layered architectures and what constitutes a good layer, and why we shouldn't pretend we have a layered architecture when we don't. Or it is about applied physics of software, understanding our material (software) and what we can really do with it. Or why we should avoid guru-driven programming. You choose; either way, I hope you'll find it interesting.
