OpenWeekend was an open source and/or free software related event in Prague, Czech Republic, held annually from 2001 to 2005. It was organized by volunteers from the Silicon Hill club of Student union at Czech Technical University.
It was focused primarily on open technologies for a broad range of users, especially on their use in an academic environment.
During the five years of its existence, many speakers from various parts of the world - Czech and Slovak Republic, Germany, France and the U.S. - participated at the conference. They presented papers on various topics: security of Linux kernel and wireless networks, different problems in cryptology, programming in non-traditional languages, OS Linux kernel drivers development, the protocols IPSEC, IPv6, IP telephony, GNU systems, deployment of open technologies in government administration and many others.
Audiovisual recordings from the conference, later on freely accessible to everyone, were always produced and are available still today under open license (free for home and academic use).
Proceedings of the conference provide materials to all presented papers.
By its scope, OpenWeekend was focused on advanced users, programmers, administrators, managers and university students. However, beginners interested in presented topics could be found in the audience as well.
The event ended due to personal problems between organizers (ex-members of the Silicon Hill club) and the trademark owner (Silicon Hill club).
