I first learned C 15 years ago, I now program primarily in C#, however I know several different technologies, and I even know LISP (as an alternative to, and something not made from, C).
I embrace new technologies, concepts, and models.
I spend a lot of time reading and understanding programming, software models, coding philosophies, team development/management issues and mathematical theories or concepts.
I especially enjoy anything that might challenge the fundamental way I think about problems or what is possible.
