The first preview release of the upcoming JRuby 1.7 defaults to Ruby 1.9 runtime mode and is much faster thanks to Java 7's invokedynamic. We talked to Charles Nutter to learn more about the future of JRuby on Java 7, Fibers and his move to Red Hat.
The first RC for JRuby 1.6 is out and brings improved Ruby 1.9.2 compatibility, experimental C extensions support, improved Windows support, Ruby Gems Maven support, performance and profiling improvements and more. InfoQ talked to JRuby's Charles Nutter about JRuby 1.6, the impact of Java 7 on JRuby, new language features in Ruby and much more.
Ruby 1.9's Fibers and non-blocking I/O are getting more attention - we talked to Mohammad A. Ali of the NeverBlock project (which provides support for MySQL and PostgreSQL) and Tony Arcieri of the Revactor project.
