Have been writing C for 25 years, C++ for 20, Objective-C and Perl for 15, C# for 10, and F# and PowerShell for 5. Lots of non-trivial SQL and dimentional modeling recently (Oracle and Cognos). Almost 20 years using Mathematica for all sorts of unusual things. Some professional exposure to Verilog and VHDL.
Big fan of Clojure, Common Lisp, Haskell, and the Third Manifesto.
