This evening, I attended the Denver JUG where Venkat Subramaniam was speaking about Scala. Unfortunately, I arrived halfway through his Programming Scala
talk and didn't get a chance to learn as much as I wanted to. What I

I will continue the JPA implementation patterns series by discussing the relative merits of field access vs. property access.
The JPA specification allows two ways for the persistence provider
to access the persistent state of an entity. The persistence...
I believe : The best way to deal with architecture is to eliminate it.
Let’s start at the beginning. First, by defining architecture.

problems of a first tier application and further...
The built-in collections for Java have good performance and are nice to use – especially with the new for-loop pattern. But are there alternatives? And if so, why should I use them? (Please use the comment functionality ) The following collection...
Here is another angle on Java under the hood: "Temporary" files. Yes, Java and JavaFX create a bunch of temporary files (some of them being more permanent than others).Here is a view of some of them (my OS is Windows XP):
applications use Java annotations on their domain model classes in
