Since then I have always had a Mac, upgrading to a new iMac in 2006 and another new iMac in 2009. So in June 2003 I bought a G3 iBook running Mac OS X Jaguar.

However, in 2003 I started thinking about leaving the University and having seen a lot of other Unix admins with Apple laptops I decided to get one myself. I had an office in a building which was open 24/7 and which had fast internet courtesy of the Janet network so I didn’t need my own computer at home.

I left there in 1999 to take a job as Systems and Applications Manager at the University of Hertfordshire where I looked after Sun Microsystems workstations and servers running Solaris. We ended up with Silicon Graphics hardware running Irix so there was another flavour of Unix to add to my belt. Back in the UK in 1992 I got a job in an engineering lab where I was put in charge of choosing a system to do large-strain Finite Element Analysis of rubber components. I went on to do postgrad work in Physics at Dartmouth College in the US where I was writing simulation code in Fortran to run on a Convex and where I was involved in purchasing a Sun 3/160 (I think we ordered it with a 10 MB hard drive). In 1982 I went to Birmingham University to study Mechanical Engineering but there was hardly any use of computers (Engineering Drawing was still done with pencil and paper on a drawing board). The first time I used a computer was around 1979 when my dad brought a Rockwell AIM-65 home from the lab to play with.
