Hi Cedric,

At least you seem wiser to the merits of dynamic languages then you use to be :^) You've finally worked out that expressivity counts, good.

Another lesson for you;

They are not subservient to the corporate world and corporate culture, and they do not depend on greedy vendors. They build their own tools and make their own choices.

You're an old friend. Invokedynamic is just a bytecode. I suggest you watch the presentation.

The VW Smalltalk VM is prodution ready and Ruby would definately run faster on that. I would hazard a guess that even the Squeak VM would out perform the JVM when it comes to running Ruby code and the Squeak VM isn't even...]]> Thu, 30 Aug 2007 16:11:29 -0400 Thu, 30 Aug 2007 16:11:29 -0400 Thu, 30 Aug 2007 16:11:29 -0400 Aug 30, 2007 Paul Beckford 2 http://www.theserverside.com/discussions/thread.tss?thread_id=46697 Sure, choose the contract first approach: create a Meta-Data file. Use simple code generation (but avoid code generation in general) to create your parser and domain classes from your Meta-Data. Avoid the Maps approach, it's a maintenance...]]> Thu, 30 Aug 2007 16:10:52 -0400 Thu, 30 Aug 2007 16:10:52 -0400 Thu, 30 Aug 2007 16:10:52 -0400 Aug 30, 2007 James Watson 0 http://www.theserverside.com/discussions/thread.tss?thread_id=46697 The VW Smalltalk VM is prodution ready and Ruby would definately run faster on that.

Can you do me a favor? If you feel that my approach in the post you referenced is sub-optimal (or crap, whatever) could you explain why? Can you offer a better solution?

To explain why in detail, would take longer then I'm willing to spend here, but yes JVM versus MRI is credible, but JVM versus YARV or Strongtalk or any purpose built dynamic VM is no match, when it comes to running a dynamic...]]> Thu, 30 Aug 2007 14:35:35 -0400 Thu, 30 Aug 2007 14:35:35 -0400 Thu, 30 Aug 2007 14:35:35 -0400 Aug 30, 2007 Paul Beckford 4 http://www.theserverside.com/discussions/thread.tss?thread_id=46697 I regret. I hope you accept my apology.

+ I'm ignorant.

I won't argue with that.

At least some agreement... ;-)
