[Ground-station] Link budget

Thu Jan 21 10:47:36 PST 2021

Ruby syntax is so nice. The challenge with using it for science/engineering
has always been the lack of a killer plotting app. I'd love to see Crystal
change that, but I worked on this for years with Ruby (see: SciRuby)
without much success. It would really require a large organization to throw
its weight behind developing such a tool, IMHO.

This same thing is an issue for other languages people have suggested as
well. It's difficult to duplicate the plotting functionalities of Python
and Matlab/Octave.

I'm +1 for Python over Octave. Choice of language helps determine the
engineering culture we draw from as well, and Python ties us a bit more to
the larger software engineering community.
