Three times a year I deliver a series of Java EE 7 / Java 8 Workshops called airhacks.com (there are some seats left for December :-)). I get more and more requests to deliver the standard set workshops in other locations, but I'm a Singleton and Singletons do not scale.
My personal goal was to keep the course as short as only possible--sometimes I re-recorded the modules multiple times to shorten them. The whole course takes 3 hours of continuous coding with a few sketches. Originally I thought about 1h, so I missed the target a bit...
