“2005 was a busy year for free software. The early days of 2006 provide a good opportunity to look ahead at the wonders that the new year will bring, but it’s also good to spend a small amount of time reflecting upon what 2005 delivered. Free software technology has made even more inroads into the corporate server space. Desktop and office applications have steadily improved as well, with implementations of them on the sharp increase. Awareness of free software, the business models, philosophy and its advantages are spreading well too. All in all a lot of positive things happened during the year, and that includes the last month, December.”
NetBSD 3.0 being the most significant..at least to me Although Apache 2.2 is cool too.
