I have a fifty-year background in Engineering; Fabrication? (using a variety of tools); Electronics (starting w/ tubes (valves to you Brits) then extended to transistors, then ICs), both Analogue and Digital; Computer programming and software design.
Am a strong advocate of Linux for an operating system and Ada for programming and am a user of both.
Aside for general cleanup/fixup/wikifying I expect to be contributing specifically in the areas of computer programming generally, and the Ada programming language specifically as well as in the area of operating systems in general and Linux in particular.
