For the last 8 or so years, the jobs have been C#/.Net. Before that, Delphi. Before that, C and C++ (quite a while ago). There's also been a touch of Ruby, a couple days of PHP, and an odd smattering of x86 assembly.
I've been doing PHP since I started programming in middle school but have been gradually shifting to .Net (VB at my employer). Never had any interest in Ruby for whatever reason.
