I've written a book, Permaculture in Pots, on growing food in small urban spaces.
I enjoy writing on cycling and environmental issues, personal development, and well-being. Links to some of my clips are below:
What to do if your bike is stolen
You see your stolen bike on eBay: what next? (The Guardian)
Pedal Power: ditch the headaches and cycle to work
Tips to get more of your colleagues cycling to work (The Ecologist)
Devils and Demons in Tasmania
Cycling the glorious east coast of Tasmania (Australian Cyclist)
Asia at low speed
Riding a variety of rusty single-speed hire bikes in China, Vietnam, and Cambodia.
I've also written for C+, London Cyclist, and Permaculture Magazine.
My book on growing food on urban balconies and patios, “Permaculture in Pots”, is available from Permanent Publications.
I also write on Linux and related things, and am a regular contributor to Linux Format magazine, Linux Planet, and Linux Pro Magazine. I used to write a weekly Tip of the Trade column for serverwatch.com, and a blog for O’Reilly.
