Brandon DeRosier is a free software supporter, software engineer, and a hobbyist game developer living in the Greater Boston area. Driven by an early interest in programming, he took to the reverse engineering of his favorite games of his childhood; he would later write several small augmentation tools to run alongside these games. Over time, he developed his skills as a programmer—as well as an interest in music composition, animation, and interactive media. Currently, he is directing these skills and interests towards game design.

As a member of the Free Software Foundation, he understands that the concealing of source code is unethical and regressive; dedicated to the digital rights of users everywhere, he has actively participated in the development and distribution of free software.

Brandon is currently pursuing a Bachelor of Science degree in Computer Science at Wentworth Institute of Technology in Boston and takes pride in helping others learn. Occasionally, he gives lectures in classes and clubs, with hopes of encouraging interest in interactive media development with frameworks such as SFML and LWJGL.

Karol Gasiński is a programmer, entrepreneur, and traveler living in Poland, Europe.

As a member of KHRONOS group, Karol contributes to the development of OpenGL and OpenGL ES Specifications—the industry standard for high-performance graphics.

Outside of his work, Karol's biggest passion is game development and low-level programming. He has been associated with the games industry for over 6 years. In the past, he has worked on mobile versions of games such as Medieval Total War, Pro Evolution Soccer, and Silent Hill. Currently he is the founder and chairman of the Polish Conference on Computer Games Development—the biggest and fastest growing industry event in the country.

Karol gives lectures on most Polish conferences and events for game developers including WGK, GameDay, SWPC, the DigitalFrontier course, IGK, and others. You can also meet him on GDC Europe and GDC San Francisco, where each year he gathers inspiration for his new games.

Eyal Kalderon is a self-taught computer programmer and high school student. Having been introduced to the programming scene at a fairly young age, Eyal developed his early skills in Visual Basic and made a switch to C# early on. Eyal has made himself at home for several years now programming with C and C++ and using shell scripts to automate every task he finds boring. After trying SDL, Eyal switched to SFML in 2010, enjoyed it, and has been following its progress closely ever since.

Understanding the power of print, having gained much from the Internet and professional publications, Eyal chose to erect 'nullpwd' (nullpwd.wordpress.com) in March of 2010, a casual software-centered blog that acts as an unintimidating front for various software topics, such as programming, penetration systems, and the current happenings of the open source community.
