Camping
After a minor fix provided by Ola Bini (thanks Ola!) we now have Camping running under JRuby, using the ActiveRecord JDBC adapter. According to Ola, Camping under JRuby seems to run very well, and feels very snappy. I'm going to be playing with it a bit soon, and may...

Ok, perhaps the blogosphere can help with this one. I've been trying to respond to an email from Tor Norbye at Sun Microsystems since Sunday. Unfortunately, my emails seem to be shuffled off into the ether. He sent another email to me today, saying he hasn't heard back from me.<br...

Some of the local Rubyists and I were talking about publishers for a future JRuby book...ligers were brought up...and, well, here's the result.

I haven't posted anything substantive in a while, but things are moving rapidly forward. Here's a quick summary of what's been going on with JRuby:

Well now I've gone and done it.
Dear Charles,...

It's 2AM. The western world is asleep. Bats flit and chatter outside my urban Minnesota home, chasing mosquitos. My available television channels (only broadcast; I don't have cable) have been reduced to dating shows, infomercials, and evangelical fundraisers.
I'm up coding. Why?...

I love stirring up trouble. In working on the compiler for JRuby, it's become apparent that a few targetted areas could yield tremendous performance benefit even in pure-interpreted mode. I describe a bit of this evening's study here.
As an experiment, I cut out a bunch of the stuff in...

JavaPolis 2006 - Antwerp, Belgium
I have received confirmation from my employer, Ventera Corporation, that they will fund my trip to Antwerp. Hooray! I'm also planning on bringing my wife and spending the holiday season in Europe. It ought to be a great trip, right on the heels of presenting...

July 17 was a particularly big news day for JRuby. Three articles were posted, one in two places, on JRuby and the two core developers Tom and I. I present here a collection of articles and blogs that have particular significance to the Ruby+Java world.
Ruby for the Java worldJoshua...

I keep wondering if things can continue moving along so well indefinitely. JRuby's got the momentum of a steamroller shot out of a cannon these days.
Compilers...

This was originally posted to the jruby-devel mailing list, but I am desperate to be proven wrong here. We use reflection extensively to bind Ruby methods to Java impls in JRuby, and the rumors of how fast reflection is have always bothered me. What is the truth? Certainly there are...

It's not really Ruby or Java-related, but with all the noise about net neutrality the past few weeks I figured I'd put my opinions out there. I doubt any of this is particularly original, but it's where I stand.
I believe, as do most well-informed Netizens, that Verizon et al...

And it's out the door! We are currently sending out the announcement: JRuby 0.9.0 is released!
Any frequent readers out there will know there's a ton of improvements in this release. I'll be blogging a bit later on the details of each, but here's a short list:All non-native Ruby libraries...

...and it's my fault!
So...I had the proposal all ready and in the RubyConf system. I got some feedback from Tom and could have pushed the "final submit" button at any time...

Rails 1.1.4 was released on Friday to very little fanfare. It was basically a fixit release for routing logic that broke in the 1.1.3 release (which broke while fixing a security issue in 1.1.2, etc). However, there's a less visible but vastly more interesting fix (for JRubyists) also included in...

Because my last "howto" post about an Eclipse issue ended up helping someone, I'm posting another.
I have PPTP set up on my Linux-based desktop, but I had been having no end of problems with large file transfers or long-running connections over it. They appeared to freeze up or die...

Queensland University of Technology's Ruby.NET project has achieved a major milestone: their Ruby to .NET compiler is able to run and pass all the test.rb samples in the C Ruby distribution. They've got plenty more work to do to be "Ruby compatible" in any sense of the words, but they're...

I'm going to try to post more frequent, less-verbose entries to break up the time between longer articles. This is the first.
For those of you unfamiliar with it, Mongrel is a (mostly) Ruby HTTP 1.1 server, designed to escape the perils of cgi/fcgi/scgi when running web frameworks like Rails...

The great unicode debate has started up again on the ruby-talk mailing list, and for once I'm not actively avoiding it. We have been asked many times by Java folks why JRuby doesn't suport unicode, and there's really been no good answer other than "that's the way Ruby does it".<br...

JRuby now supports RubyGems, and gems install correctly from local and remote. That's a huge achievement, especially considering the extra work that was required around YAML to get to this point. However, I'll start off with the caveats this time.
JRuby is very slow to install gems. You'll see what...
