Java/JVM has historically been more popular than .NET in OSS, Startups and Enterprises, it also seems to offer the highest paying Finance jobs - but this may be anecdotal. Based on experience and from what I've seen on job boards I'd have a guess that .NET is likely a close 2nd for developing Enterprise LOB Apps - I've also seen a lot of interest from Ruby/Python and PHP but this may just be regional as I don't know what demand is like outside U.S. Java has also seen a lot of resurgence thanks to Android as have Objective-C for the same reasons thanks to iOS. LLVM is the backend for the Clang C/C++/Objective-C compiler suite that's quickly replacing GCC not to mention back ends for both Swift and Rust and also used by Emscripten - its appeal and usage extends far beyond just iOS and Android. Both Rust and Go are the most likely replacements to C/C++ for future systems programming and the primary candidates for recent calls in rewriting existing UNIX utils in a safer modern language. Go is also a force on the server: https://github.com/golang/go/wiki/GoUsers https://github.com/golang/go/wiki/GoUsers - that's moved a long way from just that little language from Google. From what I've read from Hacker News and Reddit, it's getting a lot of converts from C/C++/Python/Ruby and node.js.
