Hi I've recently switched from Windows 7 to Ubuntu 12.10 and love the OS. However I have had trouble deciding which programming Language would be the all-around best for Ubuntu programming. I have no problem learning a harder language, I already know a good amount of C++ and C#. I really like C# but I've heard it doesn't mix well with Ubuntu.
What would be the best-integrated languages for Ubuntu, and good IDEs for them?
