What’s a Raspberry Pi? The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming. (from http://www.raspberrypi.org/faqs)
Do I need to own one to attend events? No. If you have some sort of ARM device, Go ahead and bring it.
What is ARM? ARM chips are the most widely-produced processor family in the world; they have historically been used in cell phones and embedded applications, and are increasingly used in tablet devices and low-power-consumption servers.
What is BAMF? Bay Area Mentoring Fedorans is a group of Open Source http://www.theopensourceway.org/ enthusiasts, their friends and family. The group is open to anyone that is able to play well with others :) Technical skills are not required. If you have a desire to try new things and learn, mentoring is available.
What is the Fedora Project? The Fedora Project creates a world where free culture is welcoming and widespread, collaboration is commonplace, and people control their content and devices. (The use of the term free culture here refers to producing Free Content in an open, collaborative environment. )
So this is only about the Fedora Project? No. As with many Fedora Proects, they not only benefit the project, but, Open Source and community in general. Ubuntu, Suse, Arch Linux folks are invited to attend. People that know nothing about computers more than welcome. People will feel comfortable learning at their own pace. Food, tech geeks, and computer novices- what's the deal? Geeknic inspired a few Bay Area folks to try out this paring. It has grown since then. "Now, with community at the heart of everything we do — it was a natural step for us to want to get out there and do something with our users, and this time we chose to literally ‘get out’ and we hope you guys will leave your computers behind and come join us in a local-ish park for a fun-filled day. We’ll eat good food, we’ll have a few drinks..." http://geeknic.org
