I was going through the exercises in Ruby Koans and I was struck by the following Ruby quirk that I found really unexplainable:

Ruby Koans is nice to learn some of those intricacies & TDD.

I think my experience in programming is in between beginner and intermediate level. Some languages I currently know are python and javascript, and I want to know ruby. I taken an interest on Ruby Koans, but if you guys can recommended other learning resources, then will be much appreciated.

Since Rails 7, there's more and more tooling that enables us, developers, to roll our own authentication. Devise is great and has been an amazing companion over the years. It also has this neat little feature - an authenticated route constraint which "hides" certain routes from people that are not signed in.

With around 50 new gems released daily, it is common to use trending libraries for managing everyday tasks. You probably use Devise for authentication, Cancan for authorization, Kaminari for pagination, or run tests with Rspec.

Devise is an authentication library built on top of Warden, a Rack-based authentication framework.
