Neat little trick to force the preview images of running programs in Windows 7 taskbar or a so called Aero Peek, to show instantly with no delay at all.
Apparently Google Glass lets you take pictures by only a wink gesture. It has a second little cam/sensor facing the person wearing it which is suppose to detect eye movement and blinking gestures.
TinEye is a great reverse image search online service, that can tell you where an image came from, find different sizes of the image and you can find out if someone is using your image without your permission.
