Marty Andrews posted a nice blog entry last month explaining how to speed up those nasty <junit><batchtest></junit>'s by building on the DirectorySuiteBuilder from junit-addons.

Marc Evers pointed me to a systems thinking website that has a very nice and simple introduction to Systems Thinking.

systems-thinking.org is the same website as systems-thinking.net but different from systemsthinking.net and systemsthinking.com. systems-thinking.com is still available ;)
