man o man so many new things to learn, i'm starting to get data overload.
I got a question though, in your example you use ubuntu live cd. As a greener then green greenhorn so am i , now i got to the point were im gonna download the BTC client, and i stumble upon this thing called PPA.
Securitywise it sounds like a possible leak to me? So can we/i trust these and why, or do we use older version or something. Plz advice
