Let's say the last time I really worked on anything Rails related was 2011-ish, and while I got stuff done OK, I never really particularly fell in love with it (and in fact was often annoyed that most projects I worked on seemed to start with a week of hacking through environment and gem snarls).
Where would people recommend I read about (a) getting up and running with rails 5 and (b) appreciating what's new and improved in the last 8 years?
I use RVM and create .ruby-version files for every single project I touch. Occasionally I'll let more than one project share a Ruby version/Gemset combo, but often I'll make sure each is unique.
No need to "bundle exec" anymore, because simply cd'ing in and out of project folders resets your gems to a clean list only required by that app. It's great. The years come and go and I still hear people complaining about Ruby version and gem hell and I wonder why the heck they aren't using RVM!
