**In this final issue of the year, we look back at the most popular Ruby and Rails news and links of 2016** so no news this week, other than [the release of Rails 5.0.1.](http://weblog.rubyonrails.org/2016/12/21/Rails-5-0-1-has-been-released/) We hope you have a happy holiday season and we'll see you in 2017 :-)

Ivan Nemytchenko[The 'Is it Ruby or Rails?' Quiz](http://railshurts.com/quiz/)This fun quiz was the most popular item this year. See if you remember _“where Ruby ends and Rails starts.”_ Neither Matz nor DHH got 10 out of 10.


John Backus[New Features in Ruby 2.4](https://blog.blockscore.com/new-features-in-ruby-2-4/)A quick, example-driven overview of numerous improvements and new features in Ruby 2.4, including `Integer#digits`, `File.empty?` and faster regex matching.

DHH also did [a fantastic 20 minute tour video](https://www.youtube.com/watch?v=OaDhY_y8WTo).

Aaron Patterson[I Am A 'puts' Debuggerer](https://tenderlovemaking.com/2016/02/05/i-am-a-puts-debuggerer.html)Don’t be ashamed if placing puts (or p) statements throughout your code is your debugging style - Ruby and Rails core team member Aaron ‘tenderlove’ Patterson does it, and shows off a ton of great examples here.


Heroku[Matz, Koichi, and Tenderlove on the Future of Ruby Performance](https://blog.heroku.com/ruby-3-by-3/)At RubyKaigi, Jonan Scheffler caught up with three of Ruby’s biggest names to talk about Ruby 3x3 and Ruby’s path to significantly improved performance.

Jesus Castello[11 Ruby Tricks You (Maybe) Haven't Seen Before](http://www.blackbytes.info/2016/01/ruby-tricks/)I knew all but one of these but I love poking around with this stuff. I’m sure you’ll find a new tidbit here, even if it’s not useful for everyday coding.


Daniel P. Clark[101 Ruby Code Factoids](http://6ftdan.com/allyourdev/2016/01/13/101-ruby-code-factoids/)A fun grab bag of interesting things (and their usage) in Ruby, from Hash#invert and IRB’s _ to unary operators and aliases. How many do you already know?
