Ottawa Linux Symposium 2007

Here is a list of activities sponsored by or of interest to CELF members at OLS 2007:

CELF Embedded Linux Projects BOF. Thanks for so many developers attending!

Overview

The CE Linux Forum is a sponsor of the 2007 Ottawa Linux Symposium.

This is our third year of sponsorship, and we really enjoy participating each year. Our participation consists of several items:

• CELF hosts its own BOF, which is open to the public
• Individual members present specific sessions at the event
• CELF members often lead or participate in BOFs
• CELF gives out prizes donated by member companies at the final keynote session of the symposium.

Note: The acronym "BOFs" stands for "Birds-of-a-Feather"session. This is an informal session where people with similar interests get together to share their ideas and plans.

CE Linux Forum Bird's of a Feather session

This BOF is for anyone interested in the latest work being done in the area of embedded Linux. We have a few interesting mini-talks on new memory measurement tools, size and bootup time reduction techniques, and experience with testing realtime features in Linux.

Please feel free to come and discuss your own embedded project.

The BOF was held at:

• Place: Westin Hotel, adjacent to the Congress Centre
• Room: Confederation Ballroom III, on the Fourth Floor
• Date: Friday, June 29
• Time: 7:00 pm to 9:00 pm

CELF BOF Agenda:
