I am planning to buy a (hopefully, inexpensive - I'm poorer than I used to be) Linux laptop to replace my Mac laptop. I'd like to be able to write & compile/interpret programs in C/C++, Python, SQL, and R. Does Ubuntu have/support all of these?
Might it be better to just buy a Windows laptop and then download Cygwin? I'd like to get Ubuntu, but I worry about cost.
