CocoaHeads Aachen

About CocoaHeads

CocoaHeads.org is an international group devoted to discussion of Apple's Cocoa Framework for programming on MacOS X. During monthly meetings, members present on their projects and offer tutorials on various programming topics.

We are the CocoaHeads Aachen Chapter, hosted by the Media Computing and Human-Computer Interaction Group at RWTH Aachen University and supported by Apple. We get together for informal short talks and demos, have a pizza, and talk code.

For a more informal get-together, check out our NSCoder Night.

When

We get together on the last Thursday of each month at 7 PM in room 2010 (see below for directions). Free food and drinks are provided courtesy of Apple.

Joining Us

Because space is limited, participation is by invitation only. To join:

1. Simply send Michael an email with your Apple/iPhone Developer ID (so we can share developer-only information), a paragraph about your current Cocoa development skills and interests, and past and current Cocoa projects. (We probably won't have to send you away without invitation, but we need to have a headcount to switch rooms if necessary, and to get enough food and drinks for everybody.)
2. Sign up for our low-traffic CocoaHeads Aachen mailing list. Michael will validate your subscription request.
3. Subscribe to our iCal calendar.
4. Follow us on Twitter.
5. Visit our group on facebook or join the global CocoaHeads group.

Directions

We meet at RWTH Aachen University, in the Computer Science Center ("Informatikzentrum"), Main Building ("Hauptbau"), ground floor, room 2010: i10 Lecture Room, Ahornstr. 55, 52074 Aachen, Germany (Google Maps).

There is a parking lot in front of the side entrance on Halifaxstraße. Here are some more detailed directions for public transport and cars.

The building will be locked around 7 p.m., so just drop in a few minutes earlier to be on the safe side... If you are late, just call +49 241 80 - 21060 so someone can open the door.
