I say some applications because there are still people using Ruby to write non-web things, and I doubt if this project will ever support Rails in the short term
Every time I played on his laptop, this did not happen. He swore he was cursed.
This went on for many days, with many instances where it would happen for him but not for me. Then one day I just sat and observed him while he played, looking for any difference. That's when I noticed his watch band is metal with a magnetic clasp. The position of his wrist on the laptop was tripping the hall sensor, making the laptop think the lid was closed.
Him and I (and his mother) were glad to find out he is not cursed. :-D
jcs did a great job designing and documenting this project. Highly recommend you try it out.
