The Berkeley Software Distribution (BSD) is a free open source version of the Unix operating system which evolved at the University of Berkeley starting from 1975, and it is based on AT&T's Unix Sixth Edition (V6). The name BSD is now used collectively for the modern descendants of these distributions. Most notable among these today is perhaps the major open source BSDs (FreeBSD, NetBSD, OpenBSD) which have themselves spawned a number of children. They are targeted at an array of systems for different purposes and are common in government facilities, universities and in commercial use. A number of commercial operating systems are also partly or wholly based on BSD or its descendants, including Apple Computer's Mac OS X.
The purpose of this one-day event is to gather Central European developers of today's open-source BSD systems, popularize their work, and provide an interface for real-life communication. There are no formalities, no papers, and no registration or participation fee, however the invited developers are encouraged to give a talk on their favorite BSD-related topic, then have a beer with the other folks around :) The language of this event is English, and the goal is to motivate potential future developers and users, especially undergraduate university students to work with BSD systems.
This year's BSD-Day was held in Naples, Italy. We are currently looking for the next year's place – maybe we could have in your country?
