I've been hacking away recently at a JVM framework for doing asynchronous, non-blocking applications using a variation of the venerable Reactor pattern. The core of the framework is currently in Java. I started with Scala then went with Java and am now considering Scala again for the core. What can I say: I'm a grass-is-greener waffler! :) But it understands how to invoke Groovy Closures, Scala anonymous functions, and Clojure functions, so you can use the framework directly without needing wrappers.

I've been continually micro-benchmarking this framework because I feel that the JVM is a better foundation on which to build highly-concurrent, highly-scalable, C100K applications than V8 or Ruby. The problem has been, so far, no good tools exist for JVM developers to leverage the excellent performance and manageability of the JVM. This yet-to-be-publicly-released framework is an effort to give Java, Groovy, Scala, [X JVM language] developers access to an easy-to-use programming model that removes the necessity

And now that I've written this, I see that Brenton already documented pretty much the same thing here. Way it goes. Figuring it out myself is better than reading about it anyway :)

ClojureScript One is pretty nice and very well-documented. Despite that, it still wasn't clear to me exactly how we got from a browser request to stuff on the screen. CS1 is built around an event bus model which makes it beautifully decoupled, but hides the execution flow. Add multimethods to the mix and it's definitely a little confusing for a newcomer.

So, tonight, as a newcomer, I worked through the control flow for the initial (development) request from the browser all the way until stuff is displayed on the screen and ready for input. I found it to be an extremely enlightening exercise. The results are below, hopefully someone will find it useful.
