It's time for me to focus a lot of my energy to learning FORTRAN for high performance coding. My strongest language is by far C#, so this should be a very interesting experience to say the least. I will try and document the transition from such a modern language to FORTRAN in case someone else finds themselves going through a similar language transition.
Simply getting started is quite an awakening; it's obvious from a few google searches that the community base is much smaller and information harder to come by. Just finding a compiler is not so trivial....
