poet writes: The PostgreSQL Conference Series is a United States based open source conference for everyone's most advanced open source database, PostgreSQL. This year, the conference has doubled in size from previous years with 45 speakers and over 50 sessions. The conference is running from 03/25 to 03/28. Any who are interested in databases should attend. Yes, this is kind of an advertisement post. However, the PostgreSQL Conference series is a model for how Open Source conferences can be run in conjunction with the community. The FAQ explains a model that allows for donations to the United States PostgreSQL Association, the 501c3 for PostgreSQL in the United States. The conference series also generates more learning material in the form of videos and slides than any other open source conference (that I know of). If you are interested in PostgreSQL or anything around PostgreSQL, this is the conference for you!
