Charles Nutter and Thomas Enebo, better known as “The JRuby Guys”, are joining Sun this month.
Dynamically-typed languages like Ruby are only beginning to be accepted in the software mainstream, and many of the best practices and tools remain to be invented. Sun would like to ensure that the Ruby programming language, in its JRuby form, is available to the community of Java developers. Also, there is a possibility that the Java platform may prove to be an attractive deployment option for existing Ruby applications in certain scenarios.
Ruby is especially appealing to Java developers. Its a good syntax fit as it is directly applicable for a lot of things that you might use Java for, and addresses a lot of things that are a nuisance in Java.
Time for Java folks to wake-up and also Learn Ruby?
