Apple is so very helpful, aren’t they? That’s one of the reasons that they shove the notification center, with the notifications panel screen, in your face whenever you accidentally move your trackpad or mouse too close to the upper righthand corner of your screen. Annoying, isn’t it? And kind of shocking that when you go to your notifications preferences there is no way to disable the Notification Center, or even to at least make it stop flying out that notifications panel. Well, we’ve got you covered; here’s how to completely disable the Mac Notification Center.

You may be wondering “is it ok to leave my iPhone screen on all the time?” or “Will leaving my iPhone screen on damage it?” For example, you may want to run one of the digital clock apps and use your iPhone as a bedside clock.

If you get frustrated when your iPhone screen switches from the upright position (known as “portrait” view) to the horizontal orientation (known as “landscape” view) at the slightest change swivel of your wrist, you may have gone searching for a way to lock the orientation so that doesn’t happen.

Did you know that your iPhone is capturing and storing screen shots of everything you do? And while we can assume (and hope) that it deletes it as soon as it not longer needs the information, it could be relatively easy for forensics experts to uncover – essentially “undelete” – that information.

An intriguing and novel eavesdropping technique has been disclosed by a group of German scientists, who describe and demonstrate in their paper “Compromising Reflections, or How to Read LCD Monitors Around the Corner” how your monitor screen can be read from a distance, by pointing a telescope at its content reflected in nearby objects. Teapots, spoons, plastic bottles, glasses and even the surface of the user’s eye offer sufficient quality for text on the screen to be intelligible, even at long distance.
