I play with all kinds of technology and languages. Currently I'm working in C# and Web programming (HTML/CSS/jQuery) while playing in Python. Along the way I've detoured into VB (COM days - I try to repress them) and remember working on Windows desktop apps in C++ when Borland was still a player. I've worked on everything from Protocol Decoders to SNMP management tools.
It's the challenge of learning that interests me.
