miller60 writes "An air conditioning technology called the 'heat wheel' is getting a test drive in data centers, and early adopters cite impressive reductions in their power bills. The heat wheel — also known as a rotary heat exchanger or Kyoto Cooling — is a refinement of cooling systems using outside air. Rather than introducing exterior air directly into the server room (the air economization we discussed recently), the heat wheel briefly mixes the outside air and exhaust air to create an air-to-air heat exchanger. A data center in the Netherlands using this approach only has to use chillers 11 days a year." The article points out that the heat wheel is not new, but it hasn't been applied to data centers until recently.

Ostracus writes with news of another contender for a next-gen device suitable for displaying a newspaper page. It's very thin but weighs a bit more than a Kindle. "Plastic Logic, a spin-off company from the Cambridge University's Cavendish Laboratory, has recently released its design of a future electronic newspaper reader. This lightweight plastic screen copies the appearance, but not the feel, of a printed newspaper. This electronic paper technology was pioneered by the E-Ink Corporation and is used in the current generation Sony eReader and Amazon.com's Kindle. Plastic Logic's device, yet to be named, has a highly legible black-and-white display and a screen more than twice as large compared to current versions available on the market."

An anonymous reader writes "Researchers at Carnegie Mellon University's HCI Institute have developed a new input technology that allows mobile devices to use surfaces they rest on, like tables, for gestural finger input. This is achieved with some clever acoustic tricks — basically taking advantage of high frequency sound propagation through dense materials. Their video highlights some neat applications, such as controlling an MP3 player by scratching on a wall and muting a cell phone by scratching on a table. Further details are available in the academic paper (PDF)."

An anonymous reader writes with an article about AMD's Conesus chip, suggesting that it is intended to compete with Intel's Atom for the netbook market. However, CNet reports that AMD is eschewing that form factor in favor of something larger, yet still more portable than a traditional laptop. Quoting: "AMD's strategy seems solid, in my opinion. Go for a segment that is bigger and better than Netbooks. The ultraportable category (the MacBook Air being the best example) is full of attractive but expensive designs. Why not work with PC makers to offer an ultrathin, ultralight, full-featured 13-inch notebook that is priced a lot less than $1,800? Why not $600 or $700? In addition to the conventional criticism of Netbooks (small screens, tiny keyboards), an underrated fact is that many users eventually get the feeling that they're stuck with an underpowered laptop."

lobo235 writes to tell us that a new underground data center designed by Sweden's largest ISP is fit for a classic supervillain, complete with greenhouses, waterfalls, German submarine engines, simulated daylight and can withstand a hit from a hydrogen bomb. "'Rather than just concentrating on technical hardware we decided to put humans in focus,' he said. 'Of course, the security, power, cooling, network, etc, are all top notch, but the people designing data centers often (always!) forget about the humans that are supposed to work with the stuff.'"

holy_calamity writes "New Scientist reports on the latest idea from researchers trying to make microcomputers use photons in place of electrons — to make optical interconnects from strands of DNA. Mixing DNA strands with the right dye molecule upgrades them into wires for light, like microscopic optical fibers, able to absorb photons at one end and transmit them to the other. One of the neat things about using DNA is it is the right scale to play nicely with existing and future chip lithography. Quoting: 'The result is similar to natural photonic wires found inside organisms like algae, where they are used to transport photons to parts of a cell where their energy can be tapped. In these wires, chromophores are lined up in chains to channel photons.'"

chrb writes "Following hot on the heels of the G1 root exploit, Jay Freeman now has Debian ARM running on the G1. The RC30 update has fixed the root hole, but with utilities and images already available to replace the flash image with your own signed code, it looks like the manufacturer-hacker arms race is on."

arcticstoat writes "The wait for AMD's next-gen CPUs is finally over, as the company has now officially launched its first 45nm 'Shanghai' Opteron chips for servers and workstations. 'AMD's move to a 45nm process relies on immersion lithography, where a refractive fluid fills the gap between the lens and the wafer, which AMD says will result in 'dramatic performance and performance-per-watt gains.' It's also enabled AMD to increase the maximum clock speed of the Opterons from 2.3GHz with the Barcelona core to 2.7GHz with the Shanghai core. Shanghai chips also feature more cache than their predecessors, with 6MB of Level 3 cache bumping the total up to 8MB, and the chips share the same cache architecture as Barcelona CPUs, with a shared pool of Level 3 cache and an individual allocation of Level 2 cache for each core.'"

Jason Sahler writes "Recently St. Lucie County in Florida announced that it has teamed up with Geoplasma to develop the United States' first plasma gasification plant. The plant will use super-hot 10,000 degree Fahrenheit plasma to effectively vaporize 1,500 tons of trash each day, which in turn spins turbines to generate 60MW of electricity — enough to power 50,000 homes!"

arcticstoat writes "Asus' budget motherboard wing, ASRock, claims that it's found a way to load a clean boot of Windows from a full shut down in just four seconds, using its new Instant Boot technology. The technology takes advantage of the S3 and S4 features of ACPI, which normally enable the Sleep/Standby and Hibernation modes in Windows respectively. However, by calling them at different times in the boot-up and shutdown process, Instant Boot enables you to boot up to your Windows desktop in three to four seconds, even after a proper shut down. Two modes are available; Fast mode, which uses S3 and boots up in around four seconds, and Regular Mode, which uses S4 and apparently takes between 20 and 22 seconds to boot. The advantage of Instant Boot when compared with normal Sleep and Hibernation modes is that you get the advantage of a clean boot of Windows, without what ASRock calls 'accumulated garbage data,' and you also get the security of knowing that you won't lose any data if there's a power cut and you lose AC power. There's also a video of it in action at the link above."

Oldyeller89 writes "LG, Sharp, and Chunghwa Picture Tubes pleaded guilty to charges of price fixing in violation of the Sherman Antitrust Act. They fixed the prices on LCD screens used not only in their products but also in other products such as Apple's iPods. The three companies agreed to pay $585 million in fines. Perhaps this will cause the price of our TVs to drop?" The New York Times also has a story on the outcome of this case.

squoozer writes "Like many people, I am trying to cut down on the amount of energy my family and I use in order to save both the environment and my pay packet. Since I want to do this in as scientific a way as possible, I'm taking meter readings every day and recording them in a spreadsheet (OOo Calc naturally). Currently, in the UK at least, neither gas nor electricity meters can be hooked up to any sort of device that can query the meter for its current reading. Rather than climb down into the cellar every day to read the meters, it would be great if I could simply position a webcam in front of each meter and have the value logged automatically each day. The problem is that while I am a software developer (Java mostly) I have no experience in image processing (dials from the electricity meter) and don't really know where to start with this project." Does anyone have any advice for analyzing the visual data this reader would be gathering?

Destructoid has a neat post about a gamer whose condition prevents him from using a standard video game controller. With the help of a company called GimpGear, which markets devices for people with limited mobility, he designed and built a custom input device that makes use of fingers, toes, and even sips or puffs of air to control his favorite games. Pictures and a video of the setup are both available in the post.

AnInkle writes "Seagate's 1.5TB Barracuda has been available for a couple months from multiple retailers. But shortly after release, reports of random freezes appeared on several sites. The hang apparently occurs in Linux, Mac OS X, and Windows Vista when streaming video or transferring files at low speeds. After a couple of weeks of silence, Seagate has finally officially acknowledged the problem. In a response to The Tech Report, they say they're investigating the 'issue' affecting 'a small number of Barracuda 7200.11 hard drives.' Acknowledging the 'inconvenience' is a start, but most users expect at least average performance and prompt service from the capacity king of data storage." In a related story, reader Lucas123 plugs a ComputerWorld piece examining the question of Seagate's plans to stay relevant at a time when SSDs increasingly capture OEM mindshare.

Christoph Derndorfer writes "Last year OLPC's XO-laptop was among the hottest Christmas gadgets thanks to the organization's G1G1 program, where you could donate $399 to give one XO-laptop to a child in the developing world and receive one yourself in return. However in 2007 the program was only available for US and Canadian citizens. This year's program, which takes off November 17, is also available to citizens in the EU member states, Switzerland, Russia, and Turkey. This is certainly awesome news for all the OLPC / Linux / gadget enthusiasts here in Europe! P.S. Before anyone asks, these XOs will come equipped with the child-friendly Sugar platform, which is based on Fedora 9, and not Windows XP."

Khyber writes "I'm doing a little personal research into a project that tracks what changes get made to your system every time you install a program. I know there are ways of checking through Windows Restore Points, but that's not what I'm trying to do. Instead, I'm going to start with an absolutely fresh Windows XP install, take a full snapshot of the entire installation on the hard drive, and burn that to a DVD (somewhat like a backup disc with an entire snapshot of my hard drive's current contents.) With every program I install, I'm going to take another snapshot, burn to DVD, and repeat the process until I have recreated every step taken to get to my current system state (all programs installed on a separate hard drive, all registry entries etc on the OS drive, with only snapshots of the OS drive being recorded.) The purpose for all of this I'm not legally allowed to talk about, due to confidentiality requirements. Does anybody know of such a program, preferably freeware, that will accomplish my objective, and are there tools that can be used to compare the difference in drive images?"

superglaze writes to tell us that VMware has announced a large effort behind their Mobile Virtualization Platform, promising the possibility of multiple operating systems on mobile devices. "The company described MVP as a 'thin layer of software' that will be embedded in handsets and 'be optimized to run efficiently on low-power-consuming and memory-constrained mobile phones.' Asked whether MVP would offer something different from the abstraction already provided by mobile Java, VMware's European product director Fredrik Sjostedt told ZDNet UK that MVP would require less recoding. 'If you want to have an application run on a Java-specific appliance, you need to code it for Java,' Sjostedt said. 'What we're introducing with MVP is an [embedded] abstraction layer below that, between the physical hardware and the software layer.'"
