Raspberry Pi. TreeHugger. The Best Raspberry Pi Accessories. 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. 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. Open Source Project. 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. Programming. 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 memory 'world record' smashed. A fragile quantum memory state has been held stable at room temperature for a "world record" 39 minutes - overcoming a key barrier to ultrafast computers.
"Qubits" of information encoded in a silicon system persisted for almost 100 times longer than ever before. Quantum systems are notoriously fickle to measure and manipulate, but if harnessed could transform computing. The new benchmark was set by an international team led by Mike Thewalt of Simon Fraser University, Canada. "This opens the possibility of truly long-term storage of quantum information at room temperature," said Prof Thewalt, whose achievement is detailed in the journal Science. 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. For applications requiring fast access, but not necessarily data persistence after power loss, SSDs may be constructed from random-access memory (RAM).
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. Development and history Early SSDs using RAM and similar technology SSDs had origins in the 1950s with two similar technologies: magnetic core memory and card capacitor read-only store (CCROS). These auxiliary memory units (as contemporaries called them) emerged during the era of vacuum-tube computers. Flash-based SSDs Enterprise flash drives Controller 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.
Fonts. What Font is. Create a rainbow coloured eyeball using Gimp. In Gimp there are a wide variety of tools at the user’s disposal for colouring an area.
Here we are going to learn how to use the gradient tool to selectively colour an area, in this case the iris of an eye, and to make the colour appear more a part of the image than if we dropped the colour straight into the image and left it. Step 1 Our first action will be to duplicate the background layer so that we can create a selection of just the Iris and modify that part of the image without affecting the rest of the picture. To isolate the Iris draw a path around it using the Path tool. 35 Inspiring Color Palettes from Master Painters. Putting together a great color palette for your design work can be one of the most challenging aspects of any project.
And many times, color palettes are built from some source of inspiration. So why not be inspired by some of history’s greatest master artists? Colour Lovers has a lot of great tools including the ability to create color palettes auto-magically from pics you find around the web. It’s a great way to find inspiration when building your palette. Of course, computer algorithms are not perfect; they miss key accent colors frequently and make questionable decisions on extracting the dominant tones. Long story short … here are 35 color pallets extracted from the work of some amazing painters with relative ease thanks to the Colour Lovers tools:
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. How To Become A Hacker. Copyright © 2001 Eric S. Raymond As editor of the Jargon File and author of a few other well-known documents of similar nature, I often get email requests from enthusiastic network newbies asking (in effect) "how can I learn to be a wizardly hacker? ". Back in 1996 I noticed that there didn't seem to be any other FAQs or web documents that addressed this vital question, so I started this one. In a Big Network of Computers, Evidence of Machine Learning. 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. Astuces et Bricolage Informatique.
