#You should do all your LAMP development in a Virtual Machine

##Here's Why:

Many of us develop on Macintoshes. There are many reasons for this, but one of them is that it's based on a Unix platform of some sort. This allows us to run common server software such as Apache, Ruby, Python and Nodejs on our Macs.

Our computers become powerful develoment machines similar to the servers our apps will eventually live on.

Sometime we start our computer only to find Apache won't start, or MySQL can't create a PID file, or we've updated to Mountain Lion and Apache needs to be reconfigured. Death!

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

Taking your nodebot wifi

Controlling your nodebot using a USB cable is great and all, and obviously you could shell out and grab a sparkcore or some other dedicated controller but what if you've got a standard arduino and you want to take an existing nodebot wireless?

Bluetooth is an option and there's this excellent JohnnyFive wiki entry that will help you there. Bluetooth can be a bit flaky though and it's range is pretty lousy. You can also look at things like XBees and what not using point to point serial, but these are expensive and very fiddly to get working.

Really, what we want is a method of transferring data over a nice, simple, standard method, requiring little configuration, low cost and we can utilise a whole stack of the code we've already produced.

Enter the WiFi232 module. These little beauties are [available from AliExpress for $12 each](http://www.aliexpress.com/item/USR-WIFI232-T-wifi-to-uart-tt

	Mongo Concepts + Console Exercise

	For tonight's assignment, we'd like you to answer a few questions and define a couple terms as well as write the queries necessary to perform the following tasks. You can either fork and clone this readme or create a new one with your solutions. You will be using the terminal and the mongo shell for this assignment as well as notes/google to answer some of the questions

	Part I - Conceptual Review

	Define these terms and answer these questions in 1-3 sentences (some will require a bit of googling)

	Terms

	List and describe each of the primitive data types (number, string, boolean, null, undefined). What do they each represent?

	Strings are lines of text wrapped in either double or single quotation marks. Strings as a whole get saved in text, and because of this they are immutable. The original contents of a string can't be changed or modified without creating a new string and a new space in memory.

	Numbers can be integers, decimals, or negative numbers. NaN (not a number), and infinity (positive infinity and negative infinity) also fall under the number type in javascript. As a primitive data type, numbers occupy fixed positions in memory.

	Booleans have two values, either true or false. The values occupy very little memory in comparison to the other primitive data types.

	Null is essentially a place holder for no value or empty value. It is a literal and not a global object(which is one way it differs from undefined) . Null is also tricky when it comes to evaluating equality. For example, null === undefi
