This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
One of the objectives of the Architects Exam 310-052 is to know the Java 2 EE core design patterns. Now, I believe all these patterns are still core exam objectives and must be known even though some of them would not be used with the latest Java EE technologies. For example, you still need to have good understanding of things like DAO and Domain Store when the sensible thing to do would be to just use JPA.
So my question is what other patterns do you consider obsolete with latest technologies?
And can you confirm that we really need to know all these patterns?
