I'm learning more about various logging packages - Log4j for Java and its Perl port, Log4perl. I've gotten tired of doing ad hoc logging/debug statements in my programs. I think as an experiment I'm going to look at using both of these packages. equire a special class of license with a mandatory SUV driving test. I'm tired of dodging Lincoln Navigators that cross the center line when their drivers can't handle them. Forget terrorism, I have much more immediate risk to my life and safety posed to me by drivers of Ford Excursions talking on their cellphones.
