Piotr Gawron is a researcher in the field of quantum information processing. His main research topics are quantum programming languages, quantum game theory, and numerical and geometrical methods in quantum information. He works in the Quantum Computer Systems Group of the Institute of Theoretical and Applied Informatics of the Polish Academy of Sciences in Gliwice, Poland. Apart from research in theoretical aspects of computer science, he has gained practical experience in FPGA development and real-time image processing for applications in UAVs working closely with the industry. He is administrator of www.quantiki.org , a portal for the quantum information community. He is a user and strong supporter of free software. He likes hard science-fiction literature, live-action role-playing, and French rock music.
Kenneth Geisshirt is a chemist by education and a geek by nature. He has been programming for more than 25 years—the last 6 years as a subcontractor. In 1990, Kenneth first met free software, and in 1992 turned to Linux as his primary operating system (officially Linux user no. 573 at the Linux Counter). He has written books about Linux, PAM, and JavaScript—and many articles on open source software for computer magazines. Moreover, Kenneth has been a technical reviewer of books on Linux network administration, the Vim editor, and JavaScript testing.
Jordi Gutiérrez Hermoso studied mathematics in Canada and Mexico, both pure and applied respectively. He has been programming since the age of seven, when he started to learn about computers while writing silly programs in BASIC. He has been a Debian user since 2001, his first and still preferred GNU/Linux distribution, to which he now occasionally contributes with GNU Octave packaging. Since 2005, he has been an enthusiastic Octave user and started getting more involved with its development in 2010. As of 2011, he resides in Mexico and works in BlueMessaging, where he's responsible for natural language processing and artificial intelligence. An Emacs user at heart, Jordi feels at home in a GNU environment and will gladly share .emacs configurations with anyone who asks.
