It is only the inadequacy of the criminal code that saves the hackers from very serious prosecution.

I also enjoy writing my regular column for Organic Gardening magazine, so I may do more of that sort of thing in the future, if anybody wants it!

I don't think there are many people up in research who have strong ideas about things that they haven't really had experience with.

I view Linux as something that's not Microsoft-a backlash against Microsoft, no more and no less.

I wanted to separate data from programs, because data and instructions are very different.
