Well I needed to kill some time during this strange intermission period between jobs. My original 1-hour hack (less than 100 lines of code), evolved to something more flexible and useful (I hope so). Eventually my father is very happy now, instead of 1 newspaper summary he now receives He was also kind enough, to …

Recently I stumbled upon several articles and examples of this handy library called JSoup, and I wanted to give it a try. It was a good opportunity to play and experiment around with CSS Selectors. My main need was a family request. My father is a captain for the trade navy. He still travels around the oceans in big …

Despite all the above, testing is something like a lost art, many development teams ignore it, …

Like many of you out there, I am working with a multi module Maven project. It is not a huge one comparing to many systems out there, it has 15 modules, with 3 different ear deployments, lots of parametrization with property files and around 100K lines of Java code.
