Colin has authored a great many technical articles and one of the first books on embedded software ["Programming Dedicated Microprocessors"; Macmillan Education, 1986]. His most recent publication is "Embedded Software: The Works" [2nd edition; Newnes, 2012], which addresses a wide range of embedded software topics. Colin is based in the UK, where he lives with his family. Away from work, his main interests are photography, reading/writing, and food and drink. His photography is showcased at DrawingWithLight.com.
