About the Author
Stefan Sjogelid grew up in 1980s Sweden, getting hooked on 8-bit consoles, Amigas and BBSes. With a background in system and network administration, he packed his bags for Southeast Asia and continued to work in IT for many years, before love and a magic 8-ball told him to seek new opportunities in the North American continent.
The Raspberry Pi is the latest gadget to grab Stefan's attention, and after much tinkering and learning a great deal about the unique properties of the Pi, he launched the "PiLFS" (http://www.intestinate.com/pilfs) website, which teaches readers how to build their own GNU/Linux distribution and applications that are particularly useful on the Raspberry Pi.
I'd like to thank Anton for putting up with my "alt-tabbing" during our movie marathons, and a special thanks to my brother for showing me Southeast Asia, and my parents, for buying me a PC instead of a moped.
About the Reviewers
Valéry Seys is a project engineer and a brilliant, self-taught man, having started his computer studies in the early 80s. He has come a long way, from working with the cheap Sinclair ZX81, to IBM Mainframe, and Unix. He is driven by a philosophy expressed by Stephen Wolfram:
"We are in the exciting stage that everyone, whether a scientist or not, can contribute"—(Santa Fe Institute, 1984).

Preface
The Raspberry Pi was developed with the intention of promoting basic computer science in schools, but the Pi also represents a welcome return to simple, fun, and open computing.
Using gadgets for purposes other than those intended, especially for mischief and pranks, has always been an important part of adopting a new technology and making it your own.
With a $25 Raspberry Pi computer and a few common USB gadgets, anyone can afford to become a secret agent.
What this book covers
Chapter 1, Getting Up to No Good, takes you through the initial setup of the Raspberry Pi and preparing it for sneaky headless operations over the network.
Chapter 2, Audio Antics, teaches you how to eavesdrop on conversations or play pranks on friends by broadcasting your own distorted voice from a distance.
Chapter 3, Webcam and Video Wizardry, shows you how to setup a webcam video feed that can be used to detect intruders, or to stage a playback scare.
Chapter 4, Wi-Fi Pranks – Exploring your Network, teaches you how to capture, manipulate, and spy on network traffic that flows through your network.
Chapter 5, Taking your Pi Off-road, shows you how to encrypt your Pi and send it away on missions while keeping in touch via GPS and Twitter updates.

Chapter 1. Getting Up to No Good
Welcome, fellow pranksters and mischief-makers, to the beginning of your journey towards a stealthier lifestyle. Naturally, you're all anxious to get started with this cool stuff, so we'll only devote this first, short chapter to the basic steps you need to get your Raspberry Pi up and running.
First we'll get to know the hardware a little better, and then we'll go through the installation and configuration of the Raspbian operating system.
At the end of this chapter you should be able to connect to your Raspberry Pi over the network and be up-to-date with the latest and greatest software for your Pi.
A brief history lesson on the Pi
The Raspberry Pi is a credit-card-sized computer created by the non-profit Raspberry Pi Foundation in the UK. It all started when a chap named Eben Upton (now an employee at Broadcom) got together with his colleagues at the University of Cambridge's computer laboratory, to discuss how they could bring back the kind of simple programming and experimentation that was widespread among kids in the 1980s on home computers such as the BBC Micro, ZX Spectrum, and Commodore 64.
After several years of tinkering, the Foundation came up with two designs for the Raspberry Pi. The $35 Model B was released first, around February 2012, originally with 256 MB of RAM. A second revision, with 512 MB of RAM, was announced in October 2012 and around that time the Pi hardware assembly was moved from China to Sony's facility in the UK. The $25 Model A is expected to go on sale in the first quarter of 2013.
Note
What are the differences between the $25 Model A and the $35 Model B?
The Model A has only 256 MB of RAM, one USB port, and no Ethernet controller. With fewer components, the power consumption of Model A is roughly half that of Model B.
Writing Raspbian OS to the SD card
Computers can't do anything useful without an operating system, and the Pi is no exception. There is a growing collection of operating systems available for the Pi, but we'll stick with the "officially recommended" OS—the Raspbian GNU/Linux distribution.
Getting Raspbian
There are two main ways to obtain Raspbian. You can either buy it preinstalled on an SD card from your Raspberry Pi dealer, or download a Raspbian image yourself and write it to an empty SD card on a computer with an SD card slot.
Note
If you do have access to a computer but it lacks an SD card slot, it's a wise choice to invest in an external SD card reader/writer. They don't cost much and chances are you'll want to re-install or try a different operating system on your SD card sooner or later.
