The introduction to Reactive Programming you've been missing

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

While there is no way to actually switch a VDI between fixed-size and dynamic, you can clone the existing VDI into a new one with different settings with VBoxManage.

VBoxManage clonehd [old-VDI] [new-VDI] --variant Standard
VBoxManage clonehd [old-VDI] [new-VDI] --variant Fixed

If you want to expand the capacity of a VDI, you can do so with

	package week7

	object primes {

	//infinite stream builder
	def from(n: Int): Stream[Int] = n #:: from(n + 1)
	//> from: (n: Int)Stream[Int]
	//infinte stream of all natural numbers
	val nats = from(0) //> nats : Stream[Int] = Stream(0, ?)
	val m4s = nats map (_ * 4) //> m4s : scala.collection.immutable.Stream[Int] = Stream(0, ?)

	#!/bin/bash

	# Change Xcode build specs by merging OSX's specs in iPhone Simulator's specs
	# This allows to build dynamic libraries for the simulator

	PLISTBUDDY="/usr/libexec/PlistBuddy"

	ROOT=`xcode-select -print-path`
	SIM_SPECS_DIR="$ROOT/Platforms/iPhoneSimulator.platform/Developer/Library/Xcode/Specifications"
	OSX_SPECS_DIR="$ROOT/Platforms/MacOSX.platform/Developer/Library/Xcode/Specifications"

	package java8fun;

	public class Foobar {

	private String foo;
	private Integer bar;

	public Foobar(String foo, Integer bar) {
	this.foo = foo;
	this.bar = bar;

	#!/bin/bash
	IPT="/sbin/iptables"

	# Server IP
	SERVER_IP="$(ip addr show eth0 \| grep 'inet ' \| cut -f2 \| awk '{ print $2}')"

	# Your DNS servers you use: cat /etc/resolv.conf
	DNS_SERVER="8.8.4.4 8.8.8.8"

	# Allow connections to this package servers
