Credit card-sized Raspberry Pi computer gets a video cam! Just when you thought you can no longer squeeze anything else into the tiny Raspberry Pi computer, think again: the puny device is getting a video camera. A report on PC World said developers expect to make the HD camera available by early spring, though the camera's specifications have yet to be finalized. "The first cameras are expected to come with a 15-centimeter (just under 6 inches) flat cable and sell for around $25. The lens on the camera is similar to those found on many camera phones and is expected to provide 5 megapixels," PC World said. It quoted Raspberry Pi developers as saying the camera board is an alternative to using USB cameras with the Raspberry Pi. They said a camera board may give a better-quality resolution at a lower price, compared to USB-based counterparts. Raspberry Pi is a credit-card sized computer that plugs into a TV and a keyboard. While tiny, it can do many things a regular desktop PC does, including playing high-definition video. — TJD, GMA News
7 Most Notorious Computer Hacker Groups of All Time With the recent attack on PlayStation Network and a bunch of high-profile websites, computer hackers are back in the limelight again. Hackers and hacker groups were quite famous in the 80’s and 90’s but their popularity started fading since the Y2K days. Today, we are once again witnessing hackers threatening to take on giant corporations sending chills down everyone's spine. We have already featured here some of the most infamous black hat hackers of all time. This time, we will take a quick look at some of the most notorious computer hacker groups that ever existed: Masters of Deception This New York-based group was responsible for notorious acts such as downloading confidential credit card histories of stars like Julia Roberts, breaking into AT&T’s computer system and stealing credit card numbers. Legion of Doom MOD’s biggest enemy Legion of Doom was a famous hacker group founded by a hacker called Lex Luthor (real name: Vincent Louis Gelormine). Chaos Computer Club Milw0rm Anonymous

The Past, Present, and Future of Data Storage As we approach the end of 2011 and look forward to another year, we pause to reflect on the long history of data storage. Mankind's ability to create, process, store, and recall information is light years ahead of the days of cave paintings and engravings on stone tablets. Vast amounts of information can be stored on drives smaller than your thumb, and data centers are cropping up at an increasingly high rate. What does the future of data storage hold? Are we really that close to holographic drives? Is 2012 the year SSDs become mainstream? Embed this image on your site:
Solid-state drive DDR SDRAM based SSD. Max 128 GB and 3072 MB/s. PCIe, DRAM and NAND-based SSD. As of 2010[update], most SSDs use NAND-based flash memory, which retains data without power. Hybrid drives or solid state hybrid drives (SSHD) combine the features of SSDs and HDDs in the same unit, containing a large hard disk drive and an SSD cache to improve performance of frequently accessed data.[9][10][11] Development and history[edit] Early SSDs using RAM and similar technology[edit] SSDs had origins in the 1950s with two similar technologies: magnetic core memory and card capacitor read-only store (CCROS).[12][13] These auxiliary memory units (as contemporaries called them) emerged during the era of vacuum-tube computers. Later, in the 1970s and 1980s, SSDs were implemented in semiconductor memory for early supercomputers of IBM, Amdahl and Cray;[15] however, the prohibitively high price of the built-to-order SSDs made them quite seldom used.
