In the 1970s, I took professional examinations in computing through the British Computer Society (specialising in computer engineering and numerical analysis).


I am a Chartered Information Technology Professional and a Chartered Engineer


In the pioneering days before the personal computer was invented, I was the first Head of Computing at Manchester Grammar School. We had a mainframe and a minicomputer -- which despite its name was big enough to fill a room


I taught Computer Systems Architecture at Manchester Polytechnic (now Manchester Metropolitan University). My book, Fundamentals of Computing, was published in 1984


My interests now include the Linux operating system and open source software, particularly software for mathematics and statistics


I served on the Royal Society working party looking at computing in the school curriculum. The working party produced the report Shutdown or Restart?
