I installed Fedora on my Eee in hopes that it would have different kernel modules or something, no luck there either. Should I downgrade kernels to 6.24 to avoid v4l2? Any help would be greatly appreciated. Brad On Wed, Oct 22, 2008 at 2:59 PM, Bradford Barr wrote: > Sadly, no dice using the other init.

We are especially interested in submissions that describe innovative curricular materials, teaching methods, pedagogical experiences, or ways to promote student interest in AI and the participation of underrepresented groups. We welcome submissions on all aspects of AI pedagogy, including, but not limited to: - Model assignments, course syllabi, software, or other curricular resources - Implementation of the Computing Curricula 2001 Intelligent Systems area - AI classroom techniques or innovations for undergraduate and/or graduate instruction - Intelligent applications for instruction of AI and assessment of such applications - The use of robots or other hands-on equipment for teaching AI - Strategies for incorporating AI research into AI courses - Strategies for encouraging wider student interest and participation in AI - Descriptions or case studies of successful class projects or other pedagogical experiences Note: There is a separate special track for Intelligent Tutoring Systems. SUBMISSION GUIDELINES Interested authors must submit completed manuscripts for double-blind review by November 23, 2008. Submission guidelines can be obtained by referring to the conference website (http://www.flairs-22.info/). Papers will be refereed and those accepted for presentation will appear in the conference proceedings which will be published by AAAI Press. Authors may be invited to submit a revised copy of their paper to a special issue of the International Journal on Artificial Intelligence Tools (IJAIT). Questions regarding the track should be addressed to Todd Neller (http://cs.gettysburg.edu/~tneller/) or Jim Marshall (http://science.slc.edu/~jmarshall/).
