When I posted on a few easy JRuby 1.0.2 bugs a couple months ago, I got a great response. So since I'm doing a bug tracker review today for JRuby 1.1, here's a new list for intrepid developers.
DST bug in second form of Time.local - This doesn't seem like...

Groovy 1.5 Released!

The Groovy team has kicked out their second major production release, Groovy 1.5...and skipped straight from 1.0 to 1.5. Why? Perhaps because they added generics, enums, static imports, annotations, fully dynamic metaclasses, improved performance, ... and much more. I think the move to 1.5 was certainly warranted, and we've been...

OpenJDK Migration to Mercurial is Complete!

I'm really excited about this one. Kelly O'Hair reports that OpenJDK source has been fully migrated to Mercurial! This means that daily development on OpenJDK (eventually to produce Java 7 and other great things) will happen on the same repository that you, dear reader, can access from home. And it's...

Groovy in Ruby: Implement Interface with a Map

Some of you may know I participate in the Groovy community as well. I'm hoping to start contributing some development time to the Groovy codebase, but for now I've mostly been monitoring their progress. One thing the Groovy team has more experience with is integrating with Java.
Now if you...

Tab Sweep November 28

WiiHear - Streaming audio for the Wii. Very cool. It was a little spotty for me, but your results may be better. And in related news: Super Mario Galaxy is the best Mario ever. I'll post a review later.

Oracle Mix Proving JRuby is "The Best Way"?

I have a tendency to post intentionally inflammatory posts that usually end up evenly divided between "yea" and "nay". But this time, I've got Rich Manalang's post from the JRuby on Rails front lines to back me up.
Rich is one of the primaries (Rich: THE primary?) behind Oracle's new...

JRuby on ME Devices?

Roy Hayun presented his "JRuby on ME" talk this past JavaOne and got a pretty solid response. He ported a pre-1.0 JRuby to CDC by incrementally stripping out libraries and functionality that couldn't be supported. He succeeded, and yesterday delivered to us a buildable version of his JRubME 0.1 (that...

GlassFish Gem Build Instructions

Hopefully by now you've heard about the GlassFish Gem. It's a roughly 3MB gem that includes only the pieces of GlassFish necessary to launch a production JRuby on Rails server. Instead of using WAR deployment, you just run "glassfish_rails" and point at your Rails dir. The result is a multi-request...

Tab Sweep

Inspired by Tim Bray's periodic tab sweeps (Tim, do you collect unread tabs into the dozens like I do?) here's the first of hopefully many tab sweeps from me.

Bytecode Tools in Ruby: A Low-level DSL

I've been toying with the idea of rewriting the JRuby compiler in Ruby, or at least writing the appropriate plumbing that would allow someone to do something similar. Migrating the JRuby compiler may or may not be worth it, since the existing Java compiler is basically done and working well,...

Have You Written RubySpec Today?

You know Ruby. You've been coding up Ruby apps for a while now. You've seen the power and the magic that Ruby offers developers, and you've seen some of the weirder, wilder, and perhaps uglier sides of Ruby. You think you're pretty well-versed in the core classes, and you can...

The First Ruby Mailing List Translator

In response to my post about the Ruby community needing an autotranslator for the key mailing lists, due to the language barrier between English-speaking and Japanese-speaking folks, I received quite a bit of interest, and a few people are looking into automatic solutions, manual solutions, and various solutions in between...

RejectConf 4 Calls to Action: Ruby specs and JRuby failures

For those of you that don't know, RejectConf started last year at RubyConf 2006 in Denver because Ryan Davis (zenspider; author of the many parsetree-based tools like flog and heckle, part of the vlad team, and so on) had a rejected presentation and still wanted to show it off. It...

Ruby Community Seeks Autotranslator

As many of you know, Ruby was created in Japan by Yukihiro Matsumoto, and most of the core development team is still Japanese to this day. This has posed a serious problem for the Ruby community, since the language barrier between the Japanese core team and community and the English-speaking...

Updated Alioth Numbers for JRuby 1.1b1

Oh yes, you all know you love the Alioth Shootout.
Isaac Gouy has updated the JRuby numbers, and modified the default comparison to be with Ruby 1.8.6 rather than with Groovy as it was before. And true to form, JRuby is faster than Ruby on 14 out of 18 benchmarks...

Closures Prototype Applied to JRuby Compiler

A bit ago, I was catching up on my feeds and noticed that Neal Gafter had announced the first prototype of Java closures. I've been a fan of the BGGR proposal, so I thought I'd catch up on the current status and try applying it to a pain point in...
