See http://www.eecs.harvard.edu/~mdw/proj/seda/ for the original description of the SEDA architecture.

Employment predictions for 2010
January 8th, 2010
Tis’ the season for predictions into 2010. After researching data from various sources, and talking with many colleagues over the past year and into 2010, I’ve put my finger on a handful of things that popped out at me. None of these predictions are groundbreaking, they’re fairly common sense. But, I think they’re important to keep an eye on, and with the media and government telling us that the recession is over, we shouldn’t become complacent in preparing for the upcoming year.

Simplifying JPA Testing with Springs PersistenceUnitPostProcessor
December 11th, 2009
At my current client, we are writing an application that is deployed as an ear into Websphere. One of the goals of the project is to write out-of-container tests so that we dont have to build and deploy over and over again. Two of the tools we are using in this application is JPA for the ORM and Spring. Initially, we had two persistance.xml files, one for production and one for testing. Some of the differences were that the production version used a transaction type of JTA and the test version used resource local. There were a few other property differences, but otherwise they needed to be identical. At first this was ok, but as our list of classes and properties grew it became a maintenance hassle.
