Data Storage

Avoiding a Digital Dark Age 287

al0ha writes to recommend a worthwhile piece up at American Scientist on the problems of archiving and data preservation in an age where all data are stored digitally. "It seems unavoidable that most of the data in our future will be digital, so it behooves us to understand how to manage and preserve digital data so we can avoid what some have called the 'digital dark age.' This is the idea — or fear! — that if we cannot learn to explicitly save our digital data, we will lose that data and, with it, the record that future generations might use to remember and understand us. ... Unlike the many venerable institutions that have for centuries refined their techniques for preserving analog data on clay, stone, ceramic or paper, we have no corresponding reservoir of historical wisdom to teach us how to save our digital data. That does not mean there is nothing to learn from the past, only that we must work a little harder to find it."

Fuel Cell Marvel "Bloom Box" Gaining Momentum 562

Many sources are continuing to excitedly report on the latest in a long line of startups chasing the holy grail of power sources. This incarnation, the "Bloom Box" from Bloom Energy, promises a power-plant-in-a-box that you can literally put in your backyard, and has received backing from companies like eBay, Google, Staples, FedEx, and Walmart. CBS recently aired an exclusive interview with K.R. Sridhar about his shiny new box. "So what is a Bloom Box exactly? Well, $700,000 to $800,000 will buy you a 'corporate sized' unit. Inside the box are a unique kind of fuel cell consisting of ceramic disks coated with green and black 'inks.' The inks somehow transform a stream of methane (or other hydrocarbons) and oxygen into power, when the box heats up to its operating temperature of 1,000 degrees Celsius. To get a view of the cost and benefits, eBay installed 5 of the boxes nine months ago. It says it has saved $100,000 USD on energy since."

Junctionless Transistor Could Simplify Chip Making 100

An anonymous reader writes "A novel transistor architecture has been developed by a team of researchers led by Jean-Pierre Colinge at Tyndall National Institute at Cork, Ireland. Not many technology developments can be truly described as 'a breakthrough' or "revolutionary' but this might just fit the bill. It does depend on the extremely small dimensions of silicon nanowires just a few dozens of atoms wide. EE Times picked up on an announcement of a paper on the topic being published by Nature Nanotechnology."

New Linux-Based Laptop For Computer Newbies 198

Smivs writes "The BBC is carrying a report on how people confused and frustrated by computers can now turn to a laptop called Alex built just for them. Based on Linux, the laptop comes with simplified e-mail, web browsing, image editing and office software. Those who sign up for Alex pay £39.95 a month for telephone support, software updates and broadband access. The Newcastle-Based Broadband Computer Company who developed Alex has been working on this project for three years, and didn't immediately adopt a Linux solution — in fact, the first big trial was based on Windows. The company's Chief Technology Officer Barney Morrison-Lyons says that was never going to be the right route: 'The biggest problem with Microsoft is badly-written software — the operating system allows you to write software badly unlike Mac or Linux.' Mr. Hudson, one of the company's founders, said the company also intends to launch an application store for Alex for customers who want to add more features and functions to their computer. 'People who love Linux will be keen to develop for this,' he said."

No Glasses Needed For TI's New 3D Display 165

adeelarshad82 writes "At the MWC, TI showed off a tablet-sized device with a 3D display that doesn't require glasses, running on an existing TI OMAP3 chipset. The 3D demo showed images and video in 3D by using a standard 120-Hz LCD with a special overlay film from 3M that can direct images either towards your left or right eye. By flickering two images very quickly, running at 60 frames per second rather than the usual 30, the display transmits a different picture to each eye, creating a simulated 3D image. The 3D picture can be created using a handheld with dual 3-megapixel cameras and an 800-MHz TI OMAP 3630 chipset."

Today's Best CPUs Compared... To a Pentium 4 354

Dr. Damage writes "How do current $74 CPUs compare to the $133 ones? To exclusive $1K Extreme Editions? Interesting questions, but what if you took a five-year-old Pentium 4 at 3.8GHz and pitted it against today's CPUs in a slew of games and other applications? The results are eye-opening." Note that this voluminous comparison is presented over 18 pages with no single-page view in sight.

Please read computer graphics related books (Newman and Sproull, Foley and Van Dam) for more information. I found "Human Aspects of CAD" by Majchrzak, Chang, Barfield, etc. to be a useful source. They quote some studies done on this topic. The recommended color schemes for easiest reading are yellow (foreground) on black (background) when using Computer/TV Screen (CRT) or use white-on-black. This is when you need to read a lot of text. Now that LCDs are dominant, a fresh look needs to be taken on these color schemes. For reading on paper, black-on-white or black on any light background (cream, light gray, pastel shades). For drawing attention of the reader, red on any background is used.
