Summary
In this presentation from the JVM Languages Summit 2008, Charles Nutter discusses bringing JRuby to the JVM, why Ruby is hard to implement, JIT compilation, precompilation, core Ruby implementation, Java library method access, method call semantics, scopes, open classes, heap-based frames, library challenges, strings, regexps, I/O, green threads, POSIX features, C lib support and future plans.

Bio
Charles Nutter has been a Java developer since 1996, recently working as the senior Java architect at Ventera Corp and in September 2006 moved to Sun to work full-time on JRuby! He led the open-source LiteStep project in the late 90s and came to Ruby in the fall of 2004. Since then he has been a member of the JRuby team, helping to make it a true alternative Ruby platform.

About the conference
The 2008 JVM Language Summit is an open technical collaboration among language designers, compiler writers, tool builders, runtime engineers, and VM architects. The talks inform the audience, in detail, about the state of the art of language design and implementation on the JVM, and the present and future capabilities of the JVM itself.

    If it's so painful then why switch? We have Groovy.

    It's not painful to *use* it's painful to *create*. And most of the reasons are the same for Groovy core team as well.
