I'm a retired software man from the UK electricity supply industry. One task I had before retiring was to run the process that kept the application and system software up to date at the then five grid control centres in England. Before running the process I had to recruit the team, take them to USA for two years' on-job training (and bring them back!) and set up development and maintenance processes.
Now I spend my time learning more about the structure of the universe and processes operating in it. I also like to fiddle about with my home mini-LAN and its computers, all of which run Gentoo Linux.
