Today we can finally announce another exciting language-related event: we've hired Frank Wierzbicki of the Jython project and Ted Leung of OSAF (and a bunch of other stuff) to help with the Python story at Sun. Hooray!
Frank Wierzbicki has been tirelessly plodding away on Jython for years, since the...

Finally the full announcement is available. We're pretty excited about this one...

Greetings!
Google's Summer of Code for 2008 is starting up again, and we're looking for folks to submit proposals. The JRuby Community or Sun or me or someone will sign up as a mentoring organization, so start thinking about or discussing possible proposals. Here's a few ideas to get you...

I'm taking a break from some bug fixing to bring you this public service announcement:
Ruby's Thread#raise, Thread#kill, and the timeout.rb standard library based on them are inherently broken and should not be used for any purpose. And by extension, net/protocol.rb and all the net/* libraries that use timeout.rb are...

It's 5am in Brussels and I'm awake. That can only mean one thing. Time to blog!
This weekend I'm presenting JRuby at FOSDEM, the "Free and Open Source Developers European Meeting." I was invited to talk, and who could pass up an invitation to Belgium?...

Today, Tom got the JRuby 1.1 RC2 release out. It's an astounding collection of performance improvements and compatibility fixes. Here's Tom's JRuby 1.1 RC2 announcement.
Let's recap a little bit:There have been additional performance improvements in RC2 over RC1. Long story short, performance of most trivial numeric benchmarks approaches or...

Yes friends, I'm at Microsoft's Lang.NET symposium this week. Does this strike you as a bit peculiar?
Lang.NET is Microsoft's event for folks interested in using and implementing "alternative" languages on the CLR. From the Lang.NET site itself:Lang .NET 2008 Symposium is a forum for discussion on programming languages, managed...

Well it's been a long hard slog for the Jython team. Once thought dead, they seemed to pick up steam more and more over the past year. They got out a long awaited 2.2 release and started to work on many missing 2.3, 2.4, and 2.5 features. They started tackling...

json-lib 2.2 has been released by Andres Almiray, and he boldly claims that "it now has become the most complete JSON parsing library". It supports Java, Groovy, and JRuby quite well, and Andres has an extensive set of json-lib examples to get you started.
But this post is about a...

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...

JavaPolis 2007 - Antwerp, Belgium - December 10-14 - Sounds like a great event this year, with claims of over 3200 registrations so far. I'll be sharing the JRuby/NetBeans tutorial with Brian Leonard on the 10th and the JRuby/Rails talk with Ola Bini on the 12th. Outside of that, I'll...

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...

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...

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...

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.

As Ola reported earlier today, we've merged Joni, Marcin Mielczynski's port of Oniguruma, to JRuby trunk. Here's the description from the Oniguruma home page:
Oniguruma is a regular expressions library.The characteristics of this library is that different character encodingfor every regular expression object can be specified.The benefit for us is...

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...
