Out of determination I succeeded, even though by my calculations doing nothing for two minutes cost me $1.60 that I could have made writing code. Of course, I stopped the clock anyway when I clicked on the HN popup notification.

Edit: Just looked at the code. The programmer missed a great chance to gather some data. I would have tracked the fail events using Google Analytics so I could see how many fails on average per user from different traffic sources:

    _gaq.push(['_trackEvent', 'Fail', 'Mouse Move', 'dummy', 'dummy']);
