C++98 with a few C++11 features for work (our compiler is not really C++11 compliant at all, but it does have move semantics).
Ada for fun, though I'd say Ada 2012 is a bit like C++11 in terms of “basically a new language”. People do seem to have a perception of Ada as ‘old’, though I'm not sure why (it is, by my account, more ‘modern’ than, say, Go – actually, it's not unlike Go with a nice generics system).
I did Ada 95 back in college. Was really nice for embedded programming -- the built-in concurrency primitives are astounding, and it feels like a much safer systems programming language than C/C++
Good for you -- I am not a fan of most of the latest C++ features; it feels again like a crazy research project. Although I _am_ excited about uniform initialization (finally), despite that fact that there are slight syntax and parsing confusion issues that arise from backward compatibility (as always, in C++).
