Welcome shodruk.

@paddyg : Thanks maybe my original signature was a little pretentious and "antediluvian". But it did betray my belief that Raspberry Pi (among many other things) is going to make a big difference to the future.
Voilà, my new signature :

Hi all, I'm Alan. I'm Irish . I'm living in Orange , Vaucluse, Provence, France . I've been here almost 10 years now (and am losing my English ). I was apparently born the same year as Eben and have a matching hairstyle (not really by choice). I'm busy working on my plan to teach computers in school...
