**A look back at the best Ruby Weekly links in 2015**
 As we mentally reboot after the holiday season, we've been doing roundups in our newsletters - this week it's Ruby's turn. There's a lot to enjoy here.
_- Peter Cooper, Editor_

SitePoint[A Retrospective on Ruby in 2015](http://www.sitepoint.com/a-retrospective-on-ruby-in-2015/)A newsy roundup of what happened with Ruby in 2015 that you might enjoy.


Ben Lewis[Five Ruby Methods You Should Be Using](https://blog.engineyard.com/2015/five-ruby-methods-you-should-be-using)Walkthroughs and examples for methods like Object#tap, Array#bsearch (a Ruby 2.0-ism) and Enumerable#flat_map. You'll pick up a trick or two here.


Awesome Ruby[Awesome Ruby: A Giant, Categorized Curated List of Gems](http://awesome-ruby.com/)At least a couple of hundred gems split up into about sixty categories. This is a curated list rather than a data driven one like Ruby Toolbox.


RedisGreenSponsored[Seamless Redis Scaling and Analytics from RedisGreen](https://dashboard.redisgreen.net/new?utm_source=rubyweekly&utm_medium=email&utm_campaign=2016a&utm_content=primary&utm_term=seamless+autoscaling+performance)Get insights quickly with our analytics dashboard. Track usage and quickly identify performance bottlenecks. All plans backed by support from engineers who have been scaling Redis for years.

SitePoint[New Methods in Ruby 2.2](http://www.sitepoint.com/new-methods-ruby-2-2/)Aaron Lasseigne takes a look at some of the new things we can play with in Ruby 2.2 (but remember [2.3 is out](https://www.ruby-lang.org/en/news/2015/12/25/ruby-2-3-0-released/) now too), such as Binding#local_variables and Enumerable#slice_after, and Kernel#itself.


Christophe Limpalair[Why DHH Rejects 80% of Software Engineer Applicants](https://medium.com/@christophelimpalair/why-the-founder-of-rails-automatically-rejects-80-of-software-engineer-applicants-4e2a4d255f58)He's definitely not a fan of commented out code.


Adam Fortuna[How a Bug in My Ruby Code Cost Code School $13,000](https://www.codeschool.com/blog/2015/06/04/how-a-bug-in-my-ruby-code-cost-code-school-13000/)I think we’ve all had a moment where a bug resulted in money lost, but it takes a brave developer to write up the story.


Aaron Patterson[Tenderlove's Experience with Minitest and RSpec](http://tenderlovemaking.com/2015/01/23/my-experience-with-minitest-and-rspec.html)Aaron ‘tenderlove’ Patterson (he of the Ruby and Rails core teams) shares numerous interesting RSpec vs Minitest insights after using both in earnest. Note, however: ‘Do I care which one you use? No.’


Confreaks TV[66 Videos from RubyConf 2015](http://confreaks.tv/events/rubyconf2015)If you didn’t make it to RubyConf this year, no problem. Confreaks did a great job of recording it and sharing the videos.
