I love to automatize either by programming in Java, velocity-templates or SQL. Love also to create automatic tests, preferably for web application or command line (didn't tried coding automatic tests for non web browser applications yet!).
Currently i'm interested in developing an application for Google's Application Engine that compares prices of given list of goods from all portuguese super-markets' online stores.
Meanwhile, since i discovered stackoverflow, i literally become an enthusiastic and really addicted! This is indeed a great knowledge base tool!
