The massive hacker camp Hacking at Random 2009 has extended their early bird ticket sales until April 14th. At EUR150, they’ve already managed to sell 1000 tickets. Every two years the european hacker community gathers together to hold a multiday camp that covers topics from hacking to art and politics. 2007′s CCCamp was largely the inspiration for this year’s ToorCamp. HAR2009 is looking for people to submit presentations, workshops, and lectures as well. They’re looking for entries that are very technology focused. The call for papers deadline is May 1st. The team is hosting a field day April 18th to tour the grounds with the various hacker villages that will be setting up. The main even is August 13-16 near Vierhouten, Netherlands.
