Advertising:
The banners that appear at the top of this site are not paid. I'm showing there the brands of some websites I think, at my sole discretion, deserve a visit. I've not asked for permission to the owners of such websites to do that, and the fact that I'm choosing to link to their websites do not mean that they endorse the content that I present here. Actually, its right the opposite: it means that I respect the work they are doing and that I'm learning a lot from them.





You never change things by fighting the existing reality. To change something, build a new model that makes the existing one obsolete.
