A Note about MySQL Community Contributions
Here, I usually write about Java-related issues, like my recent posts about Java DB.
However, every once in a while I point to something outside of Java, usually turning focus on some other communities and projects managed by Sun. When this happens, I usually write on my Blogs.Sun.Com (BSC) blog, and put a pointer here.
So, as an example, most recently I have posted a brief note about some issues related to community contributions to MySQL, including some issues having to do with Sun Contributor Agreement (SCA) for MySQL.
When it comes to open-source community-based development, you might also want to re-read the experience I have summarized, as a series of Golden Rules for Open Source Contribution-Based Communities.
