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

Step 0:

Get Homebrew installed on your mac if you don't already have it

Step 1:

Install highlight. "brew install highlight". (This brings down Lua and Boost as well)

Step 2:

tmux shortcuts & cheatsheet

start new:

tmux

start new with session name:

tmux new -s myname

Vagrant Setup

This tutorial guides you through creating your first Vagrant project.

We start with a generic Ubuntu VM, and use the Chef provisioning tool to:

install packages for vim, git
create user accounts, as specified in included JSON config files
install specified user dotfiles (.bashrc, .vimrc, etc) from a git repository

Afterwards, we'll see how easy it is to package our newly provisioned VM

	Java source code:
	k = i + j;

	May compile to Java bytecode:
	iload_0
	iload_1
	iadd
	istore_2

	And may turn into Dalvik VM code:

	package com.mypackage.benchmark

	import com.mypackage.util.Logging
	import net.lag.configgy.Configgy
	import scala.collection.mutable
	import scala.collection.JavaConversions._

	import java.net.InetSocketAddress
	import java.nio.charset.Charset
	import java.util.concurrent._

	TIC-TAC-TOE
	by Evan Hahn (http://www.evanhahn.com/)

	This is a program that allows you to play tic-tac-toe against the
	computer.

	You may change the configuration (below) to make the board more than 3x3,
	or play with "white" and "black" instead of "x" and "o", and change how
