This Week in Ruby: Rubinius 2.0-rc1, Rake 10, Refactoring video, Passenger 4.0 supports JRuby, and more

By Peter Cooper / November 9, 2012

Welcome to this week's roundup of Ruby news, articles, videos, and more, cobbled together from my e-mail newsletter, Ruby Weekly.

Highlights include: Passenger 4.0 gets support for JRuby and Rubinius, Ben Orenstein's awesome refactoring video, Pat Shaughnessy's new 'Ruby Under a Microscope' book, AWS adds Ruby support to Elastic Beanstalk, and more.

Featured

Rubinius 2.0.0 Release Candidate 1
Sadly the Rubinius blog seems to be on hiatus but plenty of people noticed Rubinius 2.0.0rc1 has been tagged. Rubinius is an alternative Ruby implementation largely written in a subset of Ruby itself and the 2.0 release brings 1.9 syntax to the fore.

Pat Shaughnessy's 'Ruby Under a Microscope' Now Available
It's a great time for indie books in the Ruby world lately and this is no exception. Pat's book is a truly deep dive into Ruby's internals with lots of diagrams and lucid explanations to help you along the way.

Phusion Passenger 4.0 Now Supports JRuby and Rubinius
Phusion's popular Ruby app deployment module for Nginx and Apache takes another leap forward by extending support from just MRI to JRuby and Rubinius. This could be big.

Refactoring from Good to Great
Thoughtbot's Ben Orenstein takes a brave approach of ditching slides and going with live coding to boldly refactor where no presenter has refactored before.

Amazon Adds Ruby Support to AWS Elastic Beanstalk
Amazon's Elastic Beanstalk service provides a way to quickly deploy and manage apps within AWS's cloud of services (EC2, S3, etc.) It now supports Ruby apps by using Phusion's Passenger (I hope Amazon are paying Phusion handsomely for this :-))

Yet Another Ruby Shootout: MRI 1.9.3 vs MRI 2.0 vs Rubinius 2.0
Igor Alexandrov picks up where Antonio Cangiano left off by benchmarking MRI 1.9.3-p286, MRI 2.0.0-preview1 and Rubinius 2.0.0-rc1. As always with benchmarks, don't read too deeply but it seems Ruby 2.0.0 holds its own so far.
