It took me a month but I finally managed to register my domain name and point it to this blog; baclabs.net is a reality, I am doing this, for real. So grateful to all who encouraged me, including my wife Chiara, my friend Albert, and Ali whom I am a big fan of. I think that the greatest realization was that I do not need to put here definitive lectures. It myght be enough to tell you about thing I find out about and what I found useful.
