About Ian
I am a New Zealand and EC citizen, living and working in Hastings in the North Island of New Zealand. On March 5th in 2004 I retired from exactly 30 years with IBM UK Ltd, working in the Hursley software development lab near Winchester in the south of England. I am now an IBM Distinguished Engineer emeritus, working to my own agenda while retaining access to my colleagues and information inside IBM.
