Interview candidates
The following page has a list of people we'd like to interview for an eLinux.org feature:
 * Interviews

Foundations and Forums

 * ARM Development Discussion Forum launched by Embest
 * Embest Product User Forum
 * CE Workgroup of the Linux Foundation (formerly the CE Linux Forum)
 * Embedded Linux Conference Presentations
 * CE Workgroup page on the Linux Foundation site
 * (deprecated: old CELF home page)

Linux User Groups
One way to get involved with a bunch of like-minded Linux enthusiasts is to participate in a local Linux users group. The following site has a good database of Linux users groups:
 * www.linux.org/groups
 * CLUE LUG List - Canadian User Group listing.
 * Bangalore Beagle User Group Meet

Development Model

 * The Cathedral and the Bazaar
 * FIXTHIS - add more links to papers and articles about the development model

Reasons for contributing to open source

 * Open Source ROI Model - a page about return on investment from open source contributions

Community-building ideas
See a discussion thread on this at: http://lists.celinuxforum.org/pipermail/celinux-dev/2012-September/000637.html

In 2012, Tim Bird proposed 4 activities to encourage more embedded Linux collaboration and community-building:

1. Resurrect the celinux-dev mailing list 2. more focused groups at upcoming conferences. 3. I'm looking for ways to invigorate the elinux.org wiki site. 4. more involvement in and use of the LTSI kernel
 * Ideas:
 * Use it more often for discussion
 * Promote on other lists (linux-embedded...?)
 * Introduce people who are using it to each other
 * Ideas:
 * have informal meeting places for specific topical areas
 * Ideas:
 * more contests?
 * Ideas:

Other ideas:
 * a 'planet' feed or news feed for embedded linux users
 * possibly: planet.elinux.org (Bill Traynor is working on it)
 * Thomas Petazzoni made one here: http://www.emlinews.net/
 * go to http://www.emlinews.net/submit/ to submit a news article


 * help bridge between embedded and non-embedded mainline developers (a'la Arnd Bergmann)
 * see reference to Arnd here: http://lists.celinuxforum.org/pipermail/celinux-dev/2012-September/000645.html
 * Better/open discussion on funded projects for embedded Linux
 * possible projects: mini-distro for software update
 * create a Google hangout for a discussion on this

Quality Assurance
This section has links to aspects of the development model designed to provide quality assurance.

Certificate of Origin
Developers who contribute code to the Linux kernel agree to the Developer Certificate Of Origin by signing their code, with a "Signed Off By" line.
