HOPE Volleyball Summerfest (Helping Other People Everywhere, Ottawa-Carleton Inc.) celebrated 30 years of fun for a cause this year.

Some parts of the world are going through winter in swing while others are savoring summer (or suffering through it!). This variation in weather is beautifully in-sync with the variety of blog posts sprouting all over the web, especially regarding database technology.
