Currently I run Ubuntu 8.04. I started out with an ICL Perq running Unix Version 7.0 and a no-name 68K running a port of System III. Moved onto Sys V on Intel while at ICL. Did some kernel hacking and helped on a device driver on Xenix (yes Microsoft's own Unix derivative) on 286 when working with/for the spooks. I quickly (18 months) moved on to Siemens where I have to pleasure of becoming a Windows programmer (V 2.0 and V3.0) while being Siemen's representative for X/Open? PC Interworking Group. Team Leader, Group Leader, enough of management when I had 17 direct reports.
