The OTN is hosting a radio interview (with transcripts) of TheServerSide's Floyd Marinescu on the subject of the EJB Design Patterns book. The interview looks at the patterns book, where patterns came from, examples of patterns, business logic vs. domain logic, anti patterns, local interface performance, and more.
