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

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

I also have an idea for a book on biodiversity, and why and how we should be conserving it.

I have to keep up with the scientific literature as part of my job, but increasingly I found myself reading things that weren't really relevant to my academic work, but were relevant to gardening.

It's always good to take an orthogonal view of something. It develops ideas.

One is that the perfect garden can be created overnight, which it can't.

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