Ruby Weekly
Issue 380 — December 21, 2017

In this final issue of 2017, we look back at our most popular links of 2017, so no news this week, other than the author of Learn Rails 5.1 reached out to us to let us know he's made the Kindle version free for the next few days, just for all of you - grab it while you can.

We hope you have a happy holiday season and we'll see you next on January 11, 2018 :-)
