OGP - Welcome to the Open Graphics Project : HomePage Hi, this site has been down for a while. I decided to bring it back up read only. No (only) registered user is allowed to edit. I have upgraded tikiwiki, but will continue to not allow newly registered users to edit on this wiki. The Open Graphics Project (OGP) is developing graphics cards with Free-licensed specifications and Free Software drivers. We believe you have the right to own your computer and get the graphics you deserve. Currently your graphics are often restricted. The Open Graphics Project believes innovation and freedom is important. We believe your freedoms' include the right to own your computer and we welcome innovation.

Quantum Computing: Will It Be a Leap in Human Evolution? Quantum computers have the potential to solve problems that would take a classical computer longer than the age of the universe. Oxford Professor David Deutsch, quantum-computing pioneer, who wrote in his controversial masterpiece, Fabric of Reality says: "quantum computers can efficiently render every physically possible quantum environment, even when vast numbers of universes are interacting. Quantum computers can also efficiently solve certain mathematical problems, such as factorization, which are classically intractable, and can implement types of cryptography which are classically impossible. Quantum computation is a qualitatively new way of harnessing nature." Quantum computing sounds like science fiction -as satellites, moon shots, and the original microprocessor once were. But the age of computing in not even at the end of the beginning. And the development of a silicon based "quantum computer" may be only just over the horizon.

Main Page Getting Started With The Raspberry Pi Is Not As Easy As Pie The super low cost computer called the Raspberry Pi is mind-blowing and awesome. As TechCrunch recently reported, the $25 to $35 mini computer on a circuit board is designed to give kids around the globe an easy way to learn computer programming. But the Raspberry Pi is not like a computer you get from Apple or pickup at the local Best Buy. I got my hands on one of the 400,000 units that have been sold. While a $25 to $35 computer makes a nice headline, the odds are good it’s going to cost you several times that amount to get it going. You will need to connect a power supply, monitor, USB keyboard, mouse, SD memory card, and an Ethernet connection. Diagram by Paul Beech and via raspberrypi.org website The distributors selling the Raspberry Pi also sell some of the needed accessories, but they are in high demand and short supply, just like the circuit board itself. I had online help from the quick start guide on the RaspberryPi.org website, their wiki and support forums. Power Monitor
Uzebox - The ATMega Game Console About The Uzebox is a retro-minimalist 8-bit open source game console. It is based on an AVR 8-bit general purpose microcontroller made by Atmel. The particularity of the system is that it uses an interrupt driven kernel and has no frame buffer. Functions such as video signal generation, tile rendering and music mixing is done in realtime by a background task so your game can easily be developed in C. The design goal was to be as simple as possible yet have good enough sound and graphics to implement interesting games. Current Features Low parts count and cost: The system is made of only two chips and discrete components. Specifications These videos demonstrates some of the features of the Uzebox.
World's Smallest Hard Drive Built of Atoms Just 96 atoms make up one byte of magnetic storage space. - Scientists have built a magnetic storage device made of 96 atoms. - The advance could lead to tiny hard drives able to store 200 to 300 times more information than they can today. Hard drives could one day be the size of rice grains, powering music players so small they would fit inside your ear. Scientists at IBM and the German Center for Free-Electron Laser Science have built the world's smallest unit of magnetic storage, using just 96 atoms to create one byte of data. The advance could lead to tiny hard drives able to store 200 to 300 times more information than they can today. PHOTOS: 5 Computer Techs to Replace Silicon Chips "An effect that is common in nature can produce this information storage idea," said Sebastian Loth of CFEL, lead author of the research, which is being published today in the journal Science. The natural phenomenon Loth is referring to has to do with the way electrons spin inside an atom.
David A. Mellis: Fab Speakers These portable speakers are made from laser-cut wood, fabric, veneer, and electronics. They are powered by three AAA batteries and compatible with any standard audio jack (e.g. on an iPhone, iPod, or laptop). The speakers are an experiment in open-source hardware applied to consumer electronics. By making their original design files freely available online, in a way that's easy for others to modify, I hope to encourage people to make and modify them. In particular, I'd love to see changes or additions that I didn't think about and to have those changes shared publicly for others to use or continue to modify.

Top 10 Supercomputers Like this story? Get the latest data center news by e-mail or RSS, or follow us on Twitter or Facebook. The twice-a-year list of the Top 500 supercomputers documents the most powerful systems on the planet. Many of these supercomputers are striking not just for their processing power, but for their design and appearance as well. Here’s a look at the top finishers in the latest Top 500 list, which was released Monday, June 20, 2011 at the ISC 11 conference in Germany. K SUPERCOMPUTER, RIKEN Advanced Institute for Computational Science (AICS), Japan The “K” supercomputer, a joint project by Fujitsu and the RIKEN center, has overtaken China’s Tianhe-1A system to gain the top spot on the updated list. TIANHE-1A, National Supercomputing Center, Tianjin, China The Tianhe-1A, the most powerful supercomputer in the world as of November 2010. JAGUAR, Oak Ridge National Laboratory NEBULAE, China TSUBAME 2.0, GSIC Center, Tokyo Institute of Technology Continue to see Numbers Six Through 10
Pearl Biotech Gel Electrophoresis with Blue Transilluminator - see bands in real time with no UV illuminator! Solid-state drive DDR SDRAM based SSD. Max 128 GB and 3072 MB/s. PCIe, DRAM and NAND-based SSD. It uses an external power supply to make the DRAM non-volatile. 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.
adafruit June 6, 2011 AT 12:05 am Microtouch – 2.4, make your own “iTouch-like” device! Sure, the latest “iTouchy” gadgets are pretty cool. But who wants a locked down device? This product is just the Microtouch dev board (preloaded with some demo Apps), and does not include a lithium polymer battery or a microSD card. On board you will find a whole bunch of goodies: Atmega32u4 – 32KB of flash, 2.5K of RAM with usb bootloader2.8″ 320×240 16-bit color, TFT display with resistive touch screenLithium polymer battery charging via USB3-axis accelerometer, MMA7544 +-2g to +-8g resolutionMicro SD card slotBattery monitoring, backlight control and on/off switch Of course, we wouldn’t just leave you with a schematic or datasheet and say ‘good luck’! The Microtouch is powerful and fun but is not meant for microcontroller beginners! The project is a collaboration between Rossum & Ladyada! We are also carrying a lot of accessories for the board, you can see them here. In stock and shipping now. Related
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?
