This semester, I am teaching the CS1 course again. If you just teach plain Java, it isn't easy to come up with interesting lab assignments.

and Dependency Injection.
I'll keep calling it WebBeans—the alternative JavaCandi is more than I
A few days after Eclipse Galileo, Netbeans released its latest offering,
Netbeans 6.7. Here is a first look, as always from my entirely biased
I just installed Eclipse 3.5 (Galileo)—it seemed a more attractive
