The title sums up the whole problem.
To use RoR, I was suggested to use Linux, so I got a VirtualBox and got Ubuntu 13 on it, installed RVM and RoR and now I'm pretty stuck.
I need to access the MSSQL from Ruby from inside the Ubuntu, and I don't have a single clue. A question of relevance was this question, but the answer links seemed to have expired, and the one that isn't, I can't make out a method of how to do it.
Any approach suggestions?
