About Me
I'm a thirty something engineer with an interest in Computing (particularly Linux), Psychology and Mathematics. Married with three kids, I've been studying with the Open University since 2008, I'm focussing on BSc (Honours) Computing and IT (B62).
An enthusiastic but amateur runner.
Yeah and a total geek.
