Hi Marcelo,
I have grown to respect quite a bit you as well as some of the other folks who work in kernel development at conectiva in Brazil (Rik, Arnaldo..).
I have been wanting to try to read more and more about the linux kernel, and maybe(?) try to get involved, so i must ask how did you start out? Any pointers that i should follow to get to understand more deeply the kernel? I mean you are not in heavy kernel hacking and you are a few years younger than me... (My guess is that it wasnt in college, since by now you should be doing the infamous college entrance exams... aka vestibular =P)
Also it seems that you value your privacy, since there isnt much public information about you out there... Would you elaborate a little on how you got where you are? =)
Just one more thing... I feel i must say that all Brazilians and young people in general are very proud and happy to see where you are now! Thanks a lot and keep up the good work!
