A group of people from Hackeriet and others is planning to go to the Chaos Communication Camp this year. It is an international, five-day open-air event for hackers and associated life-forms and is only organized every four year.
The camp takes place near an airstrip and an aviation museum in Finowfurt, near Berlin, in Germany. Read more info on their official wiki here.
In case you plan to go too, please see our wiki page that we have set up in order to coordinate travels from/to Oslo. Feel free to add yourself to the list.
