Submission + - Vista activation cracked by brute force

Bengt writes: The Inquirer has a story about a brute force Vista key activation crack.

From TFA: The crack is a glorified guesser, and with the speed of modern PCs and the number of outstanding keys, the 25-digit serials are within range. The biggest problem for MS? If this gets widespread, and I hope it will, people will start activating legit keys that are owned by other people.

There is really no differentiating between a legit copy with a manually typed in wrong key and a hack attempt. Sure MS can throttle this by limiting key attempts to one a minute or so on new software, but the older variants are already burnt to disk. The cat is out of the bag. The crack was first mentioned on the Keznews forums, a step by step How-to can be found HERE

Submission + - How to build a video wall

alphakappa writes: I am interested in building a video wall as a personal project using recycled old laptops so that I can make use of the display controllers already present. Is there free or cheap software that can extend the display on Windows and still be capable of showing different videos on different zones (like, say run a video in one zone while showing a powerpoint presentation in another one) What tools would slashdotters use?

Submission + - Using Lasers to Speed Computer Data

Carl Bialik from WSJ writes: "The start-up Lightfleet has developed an unusual way to use lasers to speed the flow of data inside a computer, hoping to break a bottleneck that can hamper machines using many microprocessors, the Wall Street Journal reports. From the article: ' "You don't have traffic issues and messages colliding," said Jeffrey Hewitt, an analyst at the research firm Gartner Inc. "I think it is very interesting." Convincing the market about an unfamiliar technology is a tall order, Mr. Hewitt said; fully exploiting Lightfleet's technology could require rewriting programs.'"
