Hello!!! This is my first post on my blog. After many years I've finally found things that I'd like to share with people. Sharing can be useful for me and for the other. I'd help me to focus on the issues that I want to share and organize. And as I've spend many hours searching things on Internet I'm sure someone else out there my be searching for the same things, and maybe my experience and compacted information will be appropriated to someone. I'll try to post in one or two weeks with useful and well structured information. For now this is all :P
