Announcing JRubyConf 2009

Good news everybody! We're finally going to have JRubyConf!

After over 3 years of heavy development, dozens of deployments and hundreds of users, it's time for a conference for JRuby users. We've talked about it on the JRuby mailing lists, polled users, and seen other JRubyists do the same. And the chorus slowly grew: you all wanted JRubyConf more and more.

Now, thanks to Engine Yard, who's producing the conference, and to sponsors EdgeCase and ThoughtWorks, we'll host the first ever JRubyConf the day after RubyConf, on Sunday November 22nd. This should allow folks attending RubyConf to also attend JRubyConf and not have to schedule a separate trip.

So here's the details:

What: JRubyConf 2009 (the first ever!)
When: Sunday, November 22nd; the day after RubyConf 2009
Where: Same hotel as RubyConf, the Embassy Suites at San Francisco Airport. You don't even have to switch locations!
Why: Because we love you!
Price: FREE!!!

We've been putting together a wide range of talks and speakers, from the JRuby core team members to real-world users; from the latest on deploying Rails to gaming and desktop development. It's going to be a fast-paced event with something for everyone, and best of all, it's FREE!

Space is limited for the event, and you will have to register separately from RubyConf to secure your seat (but you don't have to go to RubyConf to attend JRubyConf!). Check out www.jrubyconf.com for information, registration, and so on, and be quick about it!

See you at JRubyConf 2009!

Introducing Surinx

In June of this year, I spent a few hours formulating a dynamic cousin to Duby. Duby, if you don't remember, is a static-typed language with Ruby's syntax and Java's type system. Duby supports all Ruby's literals, uses local type inference (only argument types *must* be declared), and runs as fast as Java (because it produces nearly identical bytecode). But with the advent of invokedynamic, Duby needed a playmate.

Enter "Juby". Juby is intended to be basically like Duby, in that it uses Java's types and Ruby's syntax. But it takes advantage of the new invokedynamic opcode to be 100% dynamic. Juby is a dynamic Duby, or perhaps a dynamic Java with Ruby syntax. It's not hard to comprehend.

But the name was a problem. Juby sounds like "Jewbie", a pejorative term for a Jewish person. So I sent out a call for names to the Twitterverse, ultimately ending up with far more names than I could choose from.

The name I have chosen, Surinx, has a simple story attached. You see, when James Gosling created Java, he originally named it "Oak", after the tree outside his window. So I followed his lead; the tree (a bush, really) outside my window is a lilac, Syringa vulgaris. The genus "Syringa" is derived from New Latin, based on a Greek word "surinx" meaning "shepherd's pipe" from the use of the Syringa plant's hollow stems to make pipes. Perhaps Surinx is building on the "hollow stem" of the JVM to produce something you can smoke (other dynamic languages) with. Combined with its cousin "Duby", we have quite a pair.

And in other news, the simple Surinx implementation of "fib" below (identical to Ruby) manages to run fib(40) in only 7 seconds on current MLVM (OpenJDK7 + invokedynamic and other tidbits), a five-fold improvement over JRuby's fastest mode (jruby --fast).

def fib(a)
  if a < 2
    a
  else
    fib(a - 1) + fib(a - 2)
  end
end

Given that JRuby has started to support invokedynamic, the solid performance of Surinx bodes very well for JRuby's future.

Please welcome Surinx to your language repertoire!
