There were many interesting presentations given at the Sixth Dutch Perl Workshop earlier this year in Arnhem. The event was well organized and many people showed up.
I met many really interesting people there and even had the honor of giving my own presentation in front of the dynamic and fun-loving public. My presentation was called Perl and Scrum. Here's the powerpoint.
In the evening they drank some whiskey and played this weird card game called Fluxx.
