Open Source Development: Diplomacy Training

Posted by davidvc on October 4, 2005 at 5:00 PM PDT

My friend has a story of how he was sitting on his deck with a
beer, and he noticed a little bit of wood flaking off of a post. He

Sun's support of Derby.

It only seems appropriate that my first blog entry is at the
O'Reilly Open Source Conference, a place where it seems everyone

I came here because I've just recently gotten involved in the
Apache Derby open source
project, and want to learn as much as I can about the open source
culture, community and tools.
