I am switching from OSX to Linux, which I am familiar with but have no greater experience. There are several different alternatives: archlinux, gnome, ubuntu etc. Which would you recommend for a PhD student in numerical analysis? I mainly use Julia, Fortran, C++, Python and occasionally Matlab. Thus it should be easy to get the associated compilers up and running, as installing libraries for numerical tool boxes.
Furthermore I become more familiar with the Linux environment, that being said I want an OS that doesn't require to much of me as a user.
EDIT: I am switching from OSX since I got tired of getting open source codes to compile on my Mac. Most codes and packages in my field are intended for Linux anyway.
