What is an open house at a hacker space?

Motto: "messing with hardware and software."

On March 31st, 2012, hacker spaces all over the Netherlands are opening their doors to anyone who wants to know what hackers get up to. The Netherlands currently has ten hacker spaces. A hacker space is a workshop and place to meet, where technologically interested, creative and critical viewers meet, exchange ideas and work together on projects.

"Hacking" is more than testing and breaking into computers and networks. But that's not obvious to everyone. During this day, hacker spaces in the Netherlands intend to show that the hacker community in the country has a much larger spectrum of interests, along with a rich history: for example, Dutch ISP XS4ALL has its origins in the hacker scene.

In addition, hackers want to explain during this open house what 'ethical hacking' means and why the average hacker is not a threat, but will gladly share knowledge about threats on the Internet and security issues in major ICT projects of companies and governments. Knowledge is meant be shared: this is one of the basic values of the Dutch (and international) hacker community, which dates from the beginnings of the hacker culture in Boston (USA) at the end of the 60s.

RevSpace in The Hague, at Binckhorstlaan 172, participates in this national open house as well. On March 31st, from 10:00 to 21:00, the doors are open to anyone who wants to see what hackers really have to offer. A complete list of activities and directions can be found on this page.
