Just learned this cool tip for Mac users (thanks Mike O.!) So when you’re working unplugged and really want to optimize battery usage, you can invert the colors on your screen. Just push ctrl-option-propeller-8 and whalla! and inverted screen. So why is this so cool. Well think of it this way: Every non-black pixel requires power to illuminate it. If you use Eclipse, then most likely you are seeing lots of white. By inverting the color scheme, you have greatly reduced the number of white pixels showing, and in theory is using less power. Also the inversion of colors makes it easier to read in low-light situations.
The only issue that have is that it makes it very hard to find your cursor when over a large text input contol. But I am sure there is a simple fix to that too.
Cool find no?
