Drupal, Inkscape, and Linux are the most common words in her open source dictionary. In addition to being a friendly ghost on the Inkscape forum she also enjoys photography, hiking, TED talks, and lolcats. Rigel Di Scala discovered computer graphics on a Commodore VIC-20 as a young child. Before going insane trying to render artistic landscapes using only the limited character set of his primitive 8-bit computer, he upgraded to a CBM Amiga 500 and started creating his first bitmaps with Dan Silva's Deluxe Paint II. During his college years he started working part-time as a Web developer and consultant for several institutions and companies, and later as a system administrator, journalist, and editor in the computer games industry. Today he works as a web application developer for an IT company based in Milan. He promotes and uses open-source technology exclusively in his projects. Inkscape is his tool of choice for developing vector graphics. In his free time, he likes to freeclimb, skydive, and read Reddit. I would like to thank my family for their constant support in everything I do. About the Reviewer Issa Mahasneh is an independent open source consultant with relevant experience in web development and design using open source technologies. Issa got a B.Sc. in Computer Science from the Jordan University of Science and Technology (JUST) and worked as a supervisor of the open source department in a software company located in Amman. For years, he has been involved in several projects including Drupal, Songbird, and Mozilla. Since 2009, he is the president of the Jordan Open Source Association (http:// jordanopensource.org), a non-profit organization that promotes Free Software and Free Culture in Jordan and the Arab World. A frequent speaker in open source conferences and events, Issa also organizes local BarCamps, Drupal Meetups, and Linux installation fests. I would like to thank my parents, my brother, and my sister. A special thanks to my one-year old nephew, Muhammad, who made the review of this book more challenging by randomly pressing keys on my keyboard and by constantly trying to turn off my PC! 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.
