Issue 214 — September 25, 2014
ruby-lang.org
The latest patchlevel release of the currently stable, production Ruby 2.1 series of MRI. Contains the usual array of bugfixes, along with a garbage collection tweak that reduces memory consumption.


Sonic Pi
Use Ruby-based code to compose and perform in classical and contemporary styles ranging from canons to dubstep, all in a custom made IDE. Available for the Raspberry Pi and OS X. This is a well produced project.


Pat Shaughnessy
A look at how ActiveRecord works internally, how it finds what we ask it for, and how it returns results to us as Ruby objects. Complete with code and diagrams in Pat’s typically accessible style.


Semaphore
Join GitLab and other users and organizations that have cut their build time fivefold with Semaphore’s fast processors and RubyGems mirror. There is also a free plan for private projects that includes up to 100 private builds per month.

Semaphore

Michiel Sikkes
Walks through installing Docker on a VPS, setting up a Dockerfile, building the app, bundling assets, and running the app on Docker.


Erik Michaels-Ober

MotionInMotion
A scrappy (in a good way) screencast fighting through the process necessary to get RubyMotion Android development up and running.
