In an earlier blog entry I listed my picks for DevNexus 2014. This blog entry summarizes my notes from this show.
I corroborate the common wisdom about DevNexus being a very well run show. This was my first time presenting and I found the talk selection on the first day to have the right mix of diversity and depth for the working developer. The second day was much less compelling for me,...

Oracle User Group Norway - Spring Seminar
The OUGs are not the typical place for Java developers or community managers (namely me) to be. But OUGN has been working hard to build out a decent Java track with very good speakers, and it was a chance to see how the broader Oracle community is working together when it comes to Java. Also, I was in the neighborhood, more or less, and had never been on...

Kevin already did an interview with one of the organizers, Markus Eisele, about why JavaLand is different. (https://weblogs.java.net/blog/editor/archive/2014/03/01/java-conferences...) But, I got to see first-hand if they...

Introduction to Class Diagram
In any project's planning phase, the programmer should describe the behaviour of the different objects that are required to satisfy business use cases. However objects can't emerge from nothing, so you need a template that describe the type of objects that the system will have. As a result, you will need to show a diagram with all the classes involved and their...
