The point is obvious. There is more than one way to burn a book. And the world is full of people running about with lit matches. Every minority ... feels it has the will, the right, the duty to douse the kerosene, light the fuse. Every dimwit editor who sees himself as the source of all dreary blanc-mange plain porridge unleavened literature, licks his guillotine and eyes the neck of any author who dares to speak above a whisper or write above a nursery rhyme.”
~Ray Bradbury

Clever screen privacy solution

In this video, the polarizing filter is removed from a computer screen and placed into glasses, resulting in a white screen for everyone around the person who’s wearing the glasses who otherwise sees it perfectly.

It’s not an easy hack, not all screens work the same way. This could work very well in a house where the whole family shares a single computer, or at a workplace where, say, HR staff work in the middle of a “cube farm”.
