I was looking for a complete example of how to dynamically generate the page numbers when you create the pdf using iText and I couldn’t find one.

Switching from XP to Vista was a lot more painful. A few things annoyed me however. I have always… Continue reading Windows 7 – middle click to close program
While reviewing the findbugs report (WMI_WRONG_MAP_ITERATOR) for a new project at work, I learned a better way to traverse a map in Java. In fact, since the first day I started coding in Java, I never thought twice about how to traverse a map. You always traverse the keys and use the key to get… Continue reading Java: BETTER way to traverse a map
Gosh, I managed to double click on the show history tags column one time viewing a file that has gazillion tags. That stretched the tags column out of its capacity.
