My presentation at JavaZone was riddled with technical difficulties this year. To make a long story short: I learned five minutes before the presentation the the projector would be inoperative for a while (turned out to be 30 minutes). This threw a wrench into my plans, as I had planned to open with a demo.
I have read many times on presentation zen about presenting without slides. But before I stood in front of four hundred people with nothing to look at except me, I didn’t really believe how effective it would be. I’ve never seen a more attentive crowd! Thanks, everybody!
I don’t know if I had dared to throw the slides away if I hadn’t been forced to do so. But my next talk, I want to do without slides, too. This really was a serendipitous mishap.
There will be a video available of the talk, sadly, I forgot this, and spoke in Norwegian when I learned it was an all-Norwegian audience. I will link to the video for my Norwegian readers as soon as it is available.
