For most of that time, I've also been a keen gardener, but for many years I failed to make the connection between gardening and science.

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

The X server has to be the biggest program I've ever seen that doesn't do anything for you.

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

In fact, we started off with two or three different shells and the shell had life of its own.

I think the major good idea in Unix was its clean and simple interface: open, close, read, and write.

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!
