From 31C3_Public_Wiki
Jump to: navigation, search

If you work on some project on 31C3 or just want to show on what you are usually working, you're encouraged to tell others about your presence and what you're doing.

So, if you like, create a page containing information about you and your project using the project form. You can also add a project section to your Assemblies page.

Reserving seats and table space for your project

This time there a lot will be different, as we want you to bring more of that Camp feeling to the Congress! There is this Assemblies thing, that should work much like Villages on the Camp, but not exactly the same way. So your project page will be for your project, but not for reserving seats.

But you feel your work will be interesting for others to come around and have a look at it or talk to you? Set up an Assembly as a home base for you and your fellow hackers and maybe even more of your projects.

Community CubeWe are creating a functional software, out-of-the-box ready, embedded in a hardware, to embrace all internet products that everybody we are using but in a freedomistic point of view.

Actually we are using “free” internet products such as dropbox, facebook, skype or gmail. But we are paying for it. Our hidden cost is our life, our data, our secrets and our privacy.

Yarnbombing 31C3This session, which is getting a tradition at XC3, will first give a colorful and practical introduction into the art of guerillaknitting, with many inspiring examples of global knit hacking - by individuals, local and global communities with trees, bridges, tanks, cars, planes, stones or power cords covered in knitting. Attendants will learn the basics of how to yarnbomb the 31C3 (or any other place indoor or outdoor). Bring knitting needles and wool but there will also be some material available (if you want to donate yarn, bring it along or bring it to the T-Shirt Shop). Lets join forces to beautify the congress centre! This time, I suggest we use the colour code of the 31C3 for yarnbombing (see long description for details on colours and measures).
