Submission + - Stubborn Intel Graphics Bug Rids Ubuntu

Submitted by jones_supa
jones_supa writes: The current long-term support version of Ubuntu (12.04) has been experiencing a remarkably tough-to-crack and widely affecting bug related to laptops using an Intel graphics solution. When the lid is closed, every now and then the desktop freezes and only the mouse cursor can be moved. Compiz is usually found hung in the process, switching to a VT afterwards works. The Freedesktop guys are also informed. Have slashdotters been bitten by this bug and possibly could offer some detective work to help the OSS community to find and apply the correct fix?

Submission + - How young is too young for Linux? 2

He replied, he did. Once I defined a user for him on xubuntu, so that he can google his homework and print related stuff. It seems he remembered the user name and password, logged on, opened Chrome, and listened to music via Youtube all by himself. For basic stuff like this, Ubuntu is simple enough for a small kid like him.
I wanted to share this, for those who think Linux is only for geeks. If you intend to do it, and approach with no prejudice, it is just a few clicks away.

Submission + - The camera that can see through frosted glass, and around corners (extremetech.com)

The most exciting facet of this innovation is that the camera uses natural light to perform the imaging — such as a lamp, or the Sun — and not lasers or X-rays. Ori Katz, Eran Small, and Yaron Silberberg of the Weizmann Institute have shown that they can accurately resolve an object that’s hiding behind nearly opaque obstacles, or around a corner (or in another room, as long as the door’s open). In both cases, the light is scattered by the obstacle (the frosted glass, the corner wall), creating what appears to be white noise — but their camera, using spatial light modulation, can take these speckles of noise and enhance them "1000-fold" (the scientists' words) to recreate the image with surprising accuracy. Back in March, MIT announced a similar innovation — but it uses a laboratory-sized setup involving a femtosecond laser and complex hardware to discern time-of-flight. The Israeli camera looks like it uses off-the-shelf parts — and the fact that it works with natural light rather than a laser is rather cool. Its primary use will be in medical imaging (it's hard to get a sharp image of inside the brain, or other organs), but wannabe superheroes might find the technology interesting as well."
