About the Author
Stefan Sjogelid
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 Canada.
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 website (http://www.intestinate.com/pilfs), which teaches readers how to build their own GNU/Linux distribution and applications that are particularly useful on the Raspberry Pi.

Free Raspberry Pi for Secret Agents
Raspberry Pi for Secret Agents. Trendy title. While I wondered how serious it could be, the author's name got my attention - Stefan Sjogelid. Now that is already promising. This is the guy behind the idea, that if you're eager enough, you can build your own Linux distribution targeted at the Raspberry Pi architecture. The whole process is thoroughly described on his dedicated web site. And expectations slowly started to rise.
Now with this book we're in for a treat. At least we don't get the usual starter point of view, and get some trickery instead. The book is very educating on an operating system level. Reading it, I was able to fill some large gaps in my modest but constantly expanding Linux knowledge. Once the reader starts, it quickly becomes clear that the installments built up are simple enough, yet powerful and effective. And I wouldn't be surprised if such tools are employed in a real-life espionage activities.
The layout of the book is presented to be dead simple. Its significance is another story :)
After the mandatory introduction of the Raspberry Pi's basics (in terms of hardware and OS) to the reader in the first chapter, the actual contents related to the main topic begin from the second one. The four sub-topics of the book are respectively: Audio, Video, WiFi and Portable Pi. The simplicity is only on the surface.
Concerning the audio tasks, at first I had a difficulty to set-up a microphone due to my profanity. Without giving the proper attention to all of the Pi's interfaces I was (wrongfully) thinking that the audio output connector can deliver also an input. After a few lessons learned and a correct setup I was ready to meet some handy tools. Most of the chapter is dedicated to the SoX tool - the working horse of the audio mechanics.
I'm not sure I liked the whole "secret agent" storyline used throughout the book. I suppose the author was either targeting a young teen demographic, or was possibly just trying to be coy. In either case it isn't really an issue, I just thought it kind of cheapened an otherwise well written book that was full of useful information. Under the guise of learning "spy tricks", the author guides you through several system administration tasks and setup of various peripherals. Kind of a silly concept IMO, but the core information is well presented nonetheless and the book was easy to read.
The requisite intro chapter was short and to the point, giving you just what you needed to know to get started. The inclusion of information related to updating the firmware was a nice touch as I haven't read about that aspect in too many places.
The chapter on audio for the Raspberry Pi was an unexpected surprise, as it had a wealth of information on ALSA command line information I wish I had months ago when I first started working with the device. I eventually found all the information I needed on the internet back then, but it was nice seeing the pertinent commands right here in this book. It doesn't go into solving driver issues or anything like that, but it does walk you through it in such a way where it's not too difficult to make adjustments. This section gets into audio processing, remote connections, audio file formats, creating alias/shortcut commands, and process scheduling. Again, while the context may be a bit contrived, I didn't see too much fluff in the content.
The third chapter is the video complement to the audio information of chapter two.
