Engine Yard Celebrates Release of JRuby 1.6

Release Candidate Delivers Enhanced Ruby Compatibility for Java Developers Programming in Ruby Plus Improved Windows support

SAN FRANCISCO, Jan. 11, 2011 – Engine Yard, the leading cloud computing Platform-as-a-Service for Ruby on Rails, today celebrated availability of the JRuby 1.6 release candidate. JRuby, a Java implementation of the Ruby programming language, is a popular open source package that delivers the full Ruby language on the Java platform (JVM).

Both enterprises and fast-growing web companies continue to choose Ruby because it provides significant productivity gains. The latest release candidate makes it even easier for developers to build applications faster by integrating with existing Java code and applications or creating entirely new applications. These Ruby apps can be deployed anywhere that Java applications are deployed, including application servers, Android mobile devices, and enterprise desktop environments such as Windows.

“JRuby has been a great help to LinkedIn with rapid application development by allowing us to leverage our existing Java libraries right in a Rails or Sinatra application,” said Jon Bettcher, Senior Software Engineer at LinkedIn. “In one instance, JRuby saved nearly a week of development effort by not having to port a proprietary library over to native Ruby code. That’s a huge win for development velocity, code reuse and developer sanity.”

“We chose JRuby to build production applications for our Fortune 500 customers, such as Cisco, because of the stability and access to existing Java libraries and resources,” said Dylan Stamat, CTO of ELC Technologies. “Using JRuby, we’ve saved hundreds to thousands of hours by leveraging existing infrastructure, monitoring tools, and developer experience. JRuby allows for rapid test driven development, and we end up with 75% less code to manage versus using Java. Plus, we can offer our customers added value and peace of mind with the Engine Yard JRuby commercial support offering.”

The JRuby core contributors, including Charles Nutter, Thomas Enebo, and Nick Sieger who work at Engine Yard, along with the entire community of JRuby contributors, over 45 developers, contributed more than 2,000 individual commits to complete JRuby 1.6 RC. Key features in JRuby 1.6 RC include: * Ruby 1.9 compatibility - JRuby continues to track the latest version of Ruby, 1.9.2. JRuby 1.6 promises improved compatibility for most 1.9 applications including support for the new encoding APIs. * Increased performance for Ruby code - JRuby 1.6 incorporates many incremental performance improvements, including faster standard libraries from Ruby 1.9, while also laying the groundwork for future development. * Improved Windows support - JRuby 1.6 delivers another round of improvements including built-in support for WIN32OLE and other compatibility fixes that make any Ruby application run as seamlessly on Windows as on any other platform.

“We’ve improved Windows support to be even better in this release which will increase the number of developers who can use JRuby and make it more accessible for enterprise developers,” said Charles Nutter, co-lead of the JRuby core team at Engine Yard. “With a record number of external contributors to JRuby this year, we’re looking forward to working with the growing community to help us enhance JRuby and build production applications.”
