Ian has worked in the computer field for decades, starting on mainframes(!) and moving to ever-smaller computers (his smallest devices with keyboards currently include a netbook running OpenBSD and a Motorola Milestone smartphone running Android). He's written several O'Reilly books over the years, including the long-ago "Checking C Programs with Lint" and the "Java Cookbook" which is available in at least ten languages. Ian also teaches computer courses for Learning Tree International and runs his own consultancy, RejmiNet Group Inc. He lives on a hobby farm north of Toronto with his wife, some of their children, a cat and some chickens - which explains, at long last, the animal on the cover of the Java Cookbook.
