There's a lot of power in executing data - generating data and executing data.

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

The average gardener probably knows little about what is going on in his or her garden.

One of my most productive days was throwing away 1,000 lines of code.

No amount of source-level verification or scrutiny will protect you from using untrusted code.

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.

So maybe I can go back to being a Gardeners' World addict again.
