Apple has released Java for Mac OS X 10.5 Update 7 for Leopard users, updating Mac OS X's J2SE 5.0 to version 1.5.0_24 and Java SE 6 to 1.6.0_20 and delivering "improved reliability, security, and compatibility for J2SE 5.0 and Java SE 6." The only details given revolve around security fixes, so it's probably worth downloading this update even if you don't anticipate using Java applets much. Also note that J2SE 1.4.2 is no longer being updated and remains disabled in this update, which requires Mac OS X 10.5.8. (Free, 122 MB)
Create Rules Based on Entourage Messages
When creating rules in Entourage 2008, you can save some time by selecting a message like those you want the rule to work on before defining the rule. That way, when you add criteria to your rule, Entourage fills in the data based on the data in the selected message. So if you wanted to filter messages containing TidBITS, you could select an issue and add a new "From Contains" criterion to a rule. Entourage will automatically fill in the email@example.com address in the criterion.
