JRuby Compiler Will Happen

Things have really been clicking along on JRuby. Tom has been knocking down Rails unit tests left and right, and more and more stuff is working. I found a nice little performance booster that gives us as much as 30-40% speed increase when starting up. Other folks have been working...

JRuby on Rails

After seeing David Heinemeier Hansson ask the "Groovy on Rails" project not to use that moniker (since it isn't Ruby, it isn't Rails, and it has a completely separate codebase), I figured I'd play it safe and ask him directly whether "JRuby on Rails" would be acceptable. We intend to...

Eclipse UnsatisfiedLinkError: libswt-pi-gtk-3139

I ran into this a bit ago and found no solutions online. I figured it was my duty to provide at least one posting on how I solved it, since there seems to be a lot of frustrated people out there. My eventual solution was to run with 1.5 instead...

A Personal Blog

I've decided to add a personal blog, since many other tech writers do the same (and it seemed like a good idea).

The Beginning of JRuby on Rails

It must be something of a debate in the blogosphere as to whether titles should be descriptive, possibly giving away a great secret hidden within an entry's text, or whether titles should only hint at the truth, enticing a curious and diligent reader to venture onward. The former perhaps produces...

A Ruby in the Rough

Feeling More and More Ruby with Gems
Things are speedily moving along. We have been continuing our work on Rails, but because of an unusually active JRuby community, we recently changed direction for a bit. We decided to tackle RubyGems...

It seems that JRuby is more than just an entertaining and challenging project; it's also getting attention from folks that matter at Sun Microsystems.
Tim Bray, Sun Web Technologies director and XML specification co-editor, has recently taken an interest in JRuby. He's corresponded by email with both Tom and myself,...

Enterprise Sour Grapes

Recently a post by James McGovern on Why Ruby Isn't Enterprise Ready floated my way. I felt it necessary to offer up a response. My disclaimers: I am not familiar with McGovern's past work, I am not (yet) using Ruby in the "enterprise", and I am far from a Ruby...

Rails' Generators Are Working

I considered making a post last week, to keep up my at-least-one-posting-per-week schedule. However, I had dug myself deep into Rails' generator script and the built-in generators and resolved myself to finally get them running. There were a number of more complicated issues to solve, but it felt like I...

IRB is GO!

I should post about things not working more often.
Within a few hours after my previous post, where I showed the world how IRB now starts up successfully in JRuby but does not work, I was back at it trying to fix the next few bugs preventing it from working...

Migrating from Ant to Rake?

I will admit it. I'm fed up with Ant.
My current charge has me as architect for a number of larger applications and the platform on which they run--perhaps over 1Mloc total from DB to front-end. These applications must be deployable across several environments (dev, integ, qa, ua, prod, prod...

Making Progress on Rails

I've been making good progress on my end of the Rails-on-JRuby work. I have been focusing on getting the "generate" script working, and as a result fixing multiple bugs and minor issues as they come up. Here's an update.
The most recent issue, now apparently mostly fixed, involved evaluating a...
