There's a lot of work going on right now focusing on various mechanisms for deploying JRuby-based apps. This article will summarize some of the work happening and why it's really, really important for the Ruby world.

I thought I'd make a diversion from my usual JRuby activities this weekend and ping the Jython dev list. I'd been lurking for a month or two, seeing almost no activity other than the occasional email, bug report, or request for help. There were perhaps 5 emails in the last...

Well friends, it's time for another episode of "Impossible Or Not!" Today's contender is Ruby in the browser, long desired but never achieved. There are front-ends to Ruby services, delicious Ruby-JavaScript libraries, and of course the ever-popular Ruby on Rails web framework. However, developers have been clamoring for something more.<br...

Thijs van der Vossen posts an interesting perspective on recommending Sun and how his opinion of the company has been changed by recent events. It seems that the truth is really getting out: Sun "gets it" and is rising again as a great innovator.
It's a great time to be...

Yes, it's official. News is already starting to pop up around the net about Java's open-sourcing and especially about the choice of license: GPLv2. I must admit my jaw dropped when I first heard about this a couple weeks ago, and it was a hard secret to sit on. Not...

I'm not entirely sure how to feel about this one. Apparently James McGovern believes that "the Ruby community at large should drop their current approach and embrace the JRuby stuff." He notes that Jeff Sutherland recommended the same thing for Smalltalk years ago, to save it from being left behind.<br...

The JRuby community continues to pick up steam!
A number of JRubyists have recently started actively looking at the problem of deploying Rails apps as a WAR file. Some have working prototypes as well. However the most interesting development is that a number of them have joined the jruby-extras project...

There's an interesting little poll here on favorite Java-based scripting lang:
What is your favorite Java based scripting language?...

Huzzah! Java 6 has been approved by the JCP. The final results on JSR 270 show that the voting was 13 for, none opposed, with three not voting. As I understand it, this is the final step toward officially releasing Java 6 to the masses.
Java 6 is really an...

Last night I gave my 2+ hour talk on Ruby, JRuby, and JRuby on Rails to the Gateway JUG in St Louis, and it seems to have been a resounding success. We had extremely good attendance, pushing 50 folks from what I could tell, and everyone seemed to be very...

My former employer, Ventera Corporation, is still looking to fill my old position. I was their lead/senior Java EE architect, in charge of development of EE applications for their USDA Food and Nutrition Service contracts. I worked at FNS's downtown Minneapolis office, though a large part of the development team...

Well the arrangements have all been made for my trip down to St. Louis for the November Gateway JUG meeting. I'll be presenting the usual fare, JRuby and JRuby on Rails stuff, except this time there's a few twists.
Twist One: I'll be presenting for 2+ hours...

I spent today hacking on the Ruby to Java compiler and made some good progress. Here's the highlights:
It now parses a full script rather than just single method bodies.The toplevel of the script is given its own method, and defined methods get theirs.It uses MultiStub to implement the methods,...

There's now a complete transcript of my JRuby presentation for the Rubyists of Second Life complete with my slides and all the inter-avatar discussion. It's raw and it's real, and it was a lot of fun.
Larry the Liquid has also posted a JRuby of Second Life Recap that gives...

As most of you know, I was recently at RubyConf to see the latest developments in the Ruby world and to meet up with others interested in Ruby's future. A lot's happened in the past year, and Ruby has become the big ticket language in many circles. Developers from all...

I should have tossed this in a blog entry earlier, but perhaps it's not too late.
I will be presenting JRuby to the Rubyists of Second Life this evening at 6PDT. Here's the announcement sent to Ruby-Talk, which has all the relevant info:JRuby at Rubyists of Second Life...

Some fellow name TAKAI Naoto has posted an interesting comparison of JRuby on Rails running under WEBrick versus running under AsyncWeb:
TAKAI Naoto compares WEBrick and AsyncWeb and a comical translation...

It's been approximately a year since I launched into my first redesign of the JRuby interpreter engine, and a lot has happened since then. We've gotten Rails working as well as improving compatibility to the point where most other pure Ruby apps just work. We've filled out the base set...

We've added a cleaner, simpler syntax to JRuby for including Java classes into a given namespace. It stemmed from a response of mine to a user on the JRuby mailing lists, and has been committed to trunk already. Almost everyone on the list agreed this new syntax is better.

We're proud and excited to announce that Ola Bini has officially joined the JRuby development team. Ola has proven to be one of the most valuable community contributors to JRuby, and he's shown that he's dedicated to making Ruby on the JVM a reality. He's the sole creator of the...
