Did you even read the summary or watch the video? "The really clever bit, and you might not notice it unless you look closely at the video, is that the ball bounces off real architectural features of the building — like the windows, for example." Maybe you think it's unimpressive, but many people would find this really cool. And face it...if you walked by a building that was playing a giant version of breakout, you wouldn't walk by without looking twice.

Comment Re:I love the caps lock key (Score 1) 968

...I couldn't use Emacs or shell editing without it. Beats me why it's labelled 'caps lock', though --- the other control keys on the keyboard are all labelled 'Ctrl'.

I love it too...Backspace is MUCH too far for my right pinky to reach. So much less strain on my fingers when I only have to reach over to Caps Lock with my left pinky to delete some incorrect letters.

New Solar Cell Sets World Efficiency Record 299

asoduk writes to tell us that a new world record has been set for the most efficient photovoltaic device. Topping the scale at 40.8% efficiency, the new solar cell differs significantly from the previous record holder. "Instead of using a germanium wafer as the bottom junction of the device, the new design uses compositions of gallium indium phosphide and gallium indium arsenide to split the solar spectrum into three equal parts that are absorbed by each of the cell's three junctions for higher potential efficiencies. This is accomplished by growing the solar cell on a gallium arsenide wafer, flipping it over, then removing the wafer. The resulting device is extremely thin and light and represents a new class of solar cells with advantages in performance, design, operation and cost."
