What can I say about my beloved Ruby on Rails? In my early days of using Rails, I tried to get clever about going "off the rails" with things like MongoDB, Haml and others. I've since learned that out of the box Rails is just great for almost everything I need to build. It's really grown up over the years, and may not be the hot, shiny new tech, but it's such a joy to use I don't see myself moving away from it anytime soon.
This is the current default setup I'm using for all of my new Ruby on Rails web applications. (as of Dec 2019)
