In order to test files like rspec has to be added to the ubuntu machine, and I believe I got that done with the info from previous studies. I actually previously started using C9 for developing code for class projects, and it is now a matter of seeing if that portion of the virtual machine will work. I do believe I had it working before. Otherwise, I may have to download to my local Mac again, which is probably a good relearning experience, as well.
I will now work on subnetting for my CCNA class, ie try to keep doing a bit everyday in both of these learning arenas. Onward!!!!
