PLUS, updates for Google’s Core Libraries for Java.

JRuby in the Cloud!

JRuby and Trinidad are now generally available on the Engine Yard Cloud PaaS!

“For the last two years, Engine Yard has been funding the development of JRuby and we are excited to provide fully supported JRuby for your application development. This is a major milestone for the JRuby project,” reads the announcement at the Engine Yard.

Lead JRuby developer Charles Nutter has also posted about this new support, calling it a “milestone for the wider Ruby world.”

“It’s obviously the first cloud to officially support JRuby, but it’s also the first cloud with a concurrency-capable Ruby and the first cloud supporting an alternative Ruby implementation. You get the best cloud with the best support story and one of the best Ruby implementations on one of the best VMs in the world. What’s not to love?”

The Engine Yard Cloud offers automated load balancing, persistent storage, web-based gem installs, system diagnostics and data backup/restore. A free trial is available from the Engine Yard website, which includes the JRuby and Trinidad support.

Updates for Google’s Core Libraries for Java

The Guava Google Core Libraries for Java, have reached version 10.0.
