Good (-0800 GMT-centric) afternoon to everyone. Welcome to the weekly ONJava newsletter, your guide to the new, exciting, and occasionally controversial in open source and Java. Here's what's new this week.
Chris Adamson, "QuickTime for Java" author, delicately points out that QuickTime is far more than just a convenient playback library. It's a media creation toolkit. In Making Movies from Scratch, he explains how to put together a movie, frame by frame.

Maybe it's a silly question, but how can you write software if you don't know what it should do? Similarly, why would a customer pay for software if he or she doesn't know what it should do?
Next week's articles cover JBoss clustering and a caching technique called memoization.
