I run a small project called the Technology Explorer (http://db2mc.sf.net).
The Technology Explorer (TE) is a light weight web based framework for prototyping interactive database applications. Being a flexible and customization interface (think phpMyAdmin meets Drupal or Lego for database administrators), the TE allows for rapid development of UI driven processes and visualizations of database information in hours, whereas tradition processes might take weeks or month. The TE is primarily used as a teaching tool for IBM DB2 users as well as demonstrating and prototyping new interfaces. It is also used as a management consoled across a multitude of databases and database vendors (DB2, Derby, SolidDB, MYSQL and ORACLE (Were just starting to add PostgreSQL support)).
Were always looking for help to expand our library of content for different database vendors. It take a lot of understand of a given DBMS to be able to produce useful material. I would be thrilled if someone would be interested in writing tutorial for other vendors as we are currently mainly focused around IBM DB2.
Well there you have it, my plug. Were a small project, easily accessible, low barrier to entry and contributions and still lots room for growth. If your interested come on over and take a look.
Kari: There are a lot of things we really don't want you to try at home!
Tory: Yes, try it at your neighbor's house.
