After my adventures in Hyderabad, the next stop on the tour took me to the heart of India's IT industry, where I would present my TechDays talk again for Sun Microsystems' Indian Engineering Center. But I scheduled in a little free time as well, to do some exploring.
I arrived...

I have many pictures to share, but they will have to wait for an updated post. Allow your imagination to escort you for now.
So! I had been trapped in the "green zone" at the Novotel Hyderabad for two solid days, and I think I just finally had enough of...

I just completed my talk at Tech Days Hyderabad, and I think it was resounding success. If I heard right, the total head count for my "JRuby Essentials" talk was over 1200 people, by far the largest crowd I've presented for. There was a hoard of questioners immediately after the...

Success! It is now 3:00AM in Hyderabad India, and I have checked into the Novotel in HiTec City. The flight was uneventful; I got my demos basically working and then slept the majority of the time. The immigration and customs at the airport were perhaps the least threatening of any...

I'm now relaxing at Schiphol Airport, where I've just plunked down my 10 euros for internet access. After a light breakfast, my current task is now to ensure demos are ready and working for TechDays. I discovered a bit ago that the Rails Integration project uses maven to build, and...

Yes, you read that right! I'm announcing my intent to circumnavigate the globe in only NINE DAYS spreading JRuby and joy at every stop. The Earth shall be wrapped in JRuby goodness!
To celebrate this monumental occasion, I'm inviting all developers with an interest in Ruby or Java to join...

The Phoenix Is Rising!
After being considered dead for many years, Jython is back in business with the beta 1 release of Jython 2.2. It's been teetering on the edge of 2.2 compatibility for a long time, but over the past several months the core team and several contributors have...

Things are moving along well...so well I've found time to reimplement String with byte[], work on closures in the compiler, and, well those are posts for another day. Today I update you on the progress of supporting Rails in JRuby.
Rails is quite an interesting beast. I've learned more about...

Last week Tim Bray and I were at Menlo Park to meet with the Open Source Software Society Shimane, a delegation of developers, managers, and company heads from the Shimane prefecture of Japan. They were visiting Sun to talk with us about opportunities for cooperation, Sun hardware and software, and...

My friends, the end of the road is in sight for official Rails support.
Tom, Ola, and I have been working over the past week to get remaining Rails issues wrapped up. As a result of our efforts:ActionPack is now "practically" 100% working, minus a test or two we can't...

I created JRUBY-501 to track performance improvements to Java integration, since it's come to light recently that it may be one of our biggest bottlenecks now. And I found a ripe, juicy fix already.
For every call to a Java type, we call JavaUtilities.matching_method with a list of potential methods...

Roundup!
Martin Fowler enjoys using JRuby with Velocity...

Times they are a-changing.
I posted previously on JRuby's compiler work. There have been various iterations of the compiler, many purely prototype and never intended to be completed, and a few genuine attempts at evolving toward full Ruby support. However I believe in the recent weeks I've settled on a...

Who knew writing a compiler could be so much fun.
I managed to accomplish two things tonight. It's late and I have a flight home tomorrow, so I'll be brief...

Tor, you sneaky devil. You tagged me before anyone else had a chance. You grabbed the brass ring. Kudos.
So to continue the "5 Things" meme (for the record, I really hate the word "meme"), I present for you five things you probably don't know about me. Actually, some of...

The headline says it all, really!
The TIOBE Programming Community Index measures language popularity based on "the world-wide availability of skilled engineers, courses and third party vendors" using the major search engines. It's not not a terribly scientific way to measure popularity, but I'm not sure anyone has a better...

I've been cranking away on the new compiler. I'm a bit tired and planning to get some sleep, but I've gotten the following working:
all three kinds of callslocal variablesstring, fixnum, array literals'def' for simple methods and arg listsclosuresNow that last item comes with a big caveat: I have no...

Over time I've become less convinced that hotswappable classes would be an absolute requirement for the proposed invokedynamic bytecode to be useful, and more convinced that there's a number of ways a dynamic language like Ruby or Groovy could utilize the new bytecode. This post gives a little background on...

Congratulations to the Groovy team on their release of Groovy 1.0! Groovy is another dynamic language for the JVM inspired by features in Smalltalk, Python, and of course Ruby. It's been a long time coming, and a lot of hard work involved, but Groovy 1.0 is finally here.
See the...

The team has grown again! After I asked the JRuby community to nominate a new team member, based on past code, mailing list, documentation, or other contributions, a number of folks thought Nick Sieger would be a good addition. And we agreed.
Nick is the original author of the ActiveRecord-JDBC...
