Sun reports a quarterly loss: Although he was quite happy at the Web 2.0 Expo last week, Sun Microsystems CEO Jonathan Schwartz didn’t have the greatest news today.

The loss of $34 million compared with net income of $67 million a year ago. Revenue was down half a percent to $3.27 billion from $3.28 billion a year earlier. During the quarter, Sun paid $1 billion to buy open-source database company MySQL. Any time Sun reports a loss it makes analysts and investors nervous that the bad days of a few years back might return.
