My parents, for their support with my interest in technology while growing up and over the subsequent years. The Cooking Hacks team, for their great new Raspberry Pi to Arduino Bridge shield and the various contributors over on the Cooking Hacks forum for their insights. The people at Prometheus Research, for making this a great and interesting place to work. Partyka Chevrolet, for giving me some experience on the hardware side of networking. I would also like to thank Joel Goveya and Ameya Sawant at Packt Publishing for their guidance throughout this process, and Stefan Sjogelid for his technical insights and reviews. www.it-ebooks.info About the Reviewer Stefan grew up in the 1980s with the C64 and the Amiga home computers. The ambitious goal of the Raspberry Pi Foundation, bringing fun programming back to today's youth, resonated strongly with Stefan who immediately ordered his Raspberry Pi on the launch day itself. 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. www.it-ebooks.info www.PacktPub.com Support files, eBooks, discount offers and more You might want to visit www.PacktPub.com for support files and downloads related to your book.
