I'm a freelance writer on technical and environmental issues, living in London, UK.
I spent 9 months in 2008-9 travelling to Australia overland, cycle-touring for a couple of months, living in Sydney for a while, and then travelling back to the UK by sea. My blog posts from my trip can be found at my Dreamwidth blog under the "round the world" and "australia" tags.
I had a short story, Things Found on a Beach, published on SlowTrains in Nov 2008.
My book, Linux System Administration Recipes, was published in late 2009 (UK Amazon link). I also write a weekly Tip of the Trade column for serverwatch.com, and am a regular contributor to Linux Format magazine, Linux Planet, and Linux Pro Magazine. There are links to some of my articles available via this LinuxToday search. I used to write a blog at O'Reilly (technical Linux stuff, mostly, with a little Solaris).
I've also written on cycling and environmental issues for Permaculture Magazine, C+, Australian Cyclist, and London Cyclist.
A couple of links kept here just in case they're useful to someone: my notes from a long time ago on installing Linux on my Thinkpad 760ED, and my MPhil thesis (June 2002) on dissatisfied Labour Party members and their interactions with the New Labour leadership.
