Printable Batteries Should Arrive Next Year 92

FullBandwidth writes "Paper-thin batteries that can be printed onto greeting cards or other flexible substrates have been demonstrated at Fraunhofer Research Institution for Electronic Nano Systems in Germany. The batteries have a relatively short life span, as the anode and cathode materials dissipate over time. However, they contain no hazardous materials."

Linux-Friendly, Internet-Enabled HDTVs? 277

mrchaotica writes "I'm in the market for a new HDTV (in the $1200-or-slightly-more range, as I won the extended-service-plan lottery and have a Sears store credit). Several of the TVs I've looked at have various 'Internet TV' features (here are Samsung's and Panasonic's). Some manufacturers appear to be rolling their own, while others are partnering with Yahoo (maybe in an attempt to create a 'standard?'). Moreover, these TVs also tend to run Linux under the hood (although their GPL compliance, such as in Panasonic's case, may leave something to be desired). Finally, it's easy to imagine these TVs being able to support video streaming services (YouTube, Netflix, Amazon, etc.) without a set-top box, but I don't know the extent to which that support actually exists. Here are my questions: 1) Is this 'Internet TV' thing going to be a big deal going forward, or just a gimmick? 2) Which manufacturers are most [open standard|Linux|hacker]-friendly? 3) Which TV models have the best support (or best potential and community backing) for this sort of thing?"

Garbage Collection Algorithms Coming For SSDs 156

MojoKid writes "A common concern with the current crop of Solid State Drives is the performance penalty associated with block-rewriting. Flash memory is comprised of cells that usually contain 4KB pages that are arranged in blocks of 512KB. When a cell is unused, data can be written to it relatively quickly. But if a cell already contains some data, even if it fills only a single page in the block, the entire block must be re-written. This means that whatever data is already present in the block must be read, then it must be combined or replaced, and the entire block is then re-written. This process takes much longer than simply writing data straight to an empty block. This isn't a concern on fresh, new SSDs, but over time, as files are written, moved, deleted, or replaced, many blocks are a left holding what is essentially orphaned or garbage data, and their long-term performance degrades because of it. To mitigate this problem, virtually all SSD manufacturers have incorporated, or soon will incorporate, garbage collection schemes into their SSD firmware which actively seek out and remove the garbage data. OCZ, in combination with Indilinx, is poised to release new firmware for their entire line-up of Vertex Series SSDs that performs active garbage collection while the drives are idle, in order to restore performance to like-new condition, even on a severely 'dirtied' drive."

Nano Origami for DNA, Complete With Software 32

wisebabo writes "Some researchers at Technische Universitaet Muenchen and Harvard have developed a way to make DNA 'Origami' fold up into all sorts of desired nanoscale shapes. While this has been done before, there now seems to be a much greater assortment of shapes they can create. What's particularly interesting is that they've developed some software that can be used (presumably with a DNA assembler) that will create what you want; think of CAD/CAM on a molecular scale! 'The toolbox they have developed includes a graphical software program that helps to translate specific design concepts into the DNA programming required to realize them. Three-dimensional shapes are produced by "tuning" the number, arrangement, and lengths of helices.'"

Microsoft Hardware Demos Pressure-Sensitive Keyboard 212

Krystalo writes to tell us that Microsoft hardware has an interesting demo of a pressure-sensitive keyboard they have designed. While there are no currently announced plans to turn this into a shipping product, there are many cool uses that one could imagine a device like this providing. "The device will be put to use in the first annual Student Innovation Contest in Victoria, Canada, where contestants will be supplied with a keyboard prototype and challenged with developing new interactions for it. Contestants will demo their creations and attendees will vote for their favorite at the conference on October 5. $2,000 prizes will be given to the authors of programs deemed as the most useful, the best implementation, and the most innovative."

LHC To Start Back Up In November At Half Power 110

mcgrew writes to mention that the Large Hadron Collider, smasher of particles, will get another chance to prove itself this November. The restart will begin with tests at half power, a mere 7 trillion electron volts (TeV), and ramp up slowly to the designed goal of 14 TeV. "Measurements indicate that some of the electrical connections could not safely handle the amount of current needed to run at the full 14 TeV, so will need to be replaced before dialing up the energy that far. But even 7 TeV is much higher than physicists have ever probed in the laboratory before. The Tevatron accelerator at Fermilab in Batavia, Illinois, is the current record holder, with collisions at 2 TeV."

Sony Takes Aim At Amazon's Kindle 273

MojoKid writes "Sony recently announced two new eBook readers and has set its sights on tapping into Amazon's Kindle market share. The Sony Reader Pocket Edition and the Reader Touch Edition will come out at the end of the month and will reportedly cost less or the same as the older, more established Kindle. The Pocket Edition has a five-inch display, comes in several colors ('including navy blue, rose and silver') and fits, as one might expect, in a jacket pocket or a purse. It can store about 350 'standard eBooks' and can last about two weeks on a single charge, Sony claims. The Touch Edition is a bit larger, with a six-inch display that, as you'd expect, can be controlled via a touch interface."

How Can I Tell If My Computer Is Part of a Botnet? 491

ashraya writes "My father (not too computer literate) has a desktop and a laptop both running Windows in his network back in Hyderabad, India. I set up a Linksys router for him to use with his broadband service. For some reason, he reset the config on the Linksys, and connected it up without wireless security, and also with the default admin password for some time. As you would expect, both of the Windows computers got 'slow,' and the desktop stopped connecting to the internet completely for some reason. As I logged in remotely to 'fix' things, I noticed on the Linksys' log that the laptop was making seemingly random connections to high-numbered ports on various IPs. I did an nslookup on the IPs to see that they were all either in Canada or US, with Comcast and other ISP addresses. Is that a sign that the computers were in a botnet? Are the other hosts part of the botnet too? (I have since rebuilt the Windows hosts, and these connections are not happening now. I have also secured the Linksys.)"

Apple Working On Tech To Detect Purchasers' "Abuse" 539

Toe, The writes "Apple has submitted a patent application for technologies which would detect device-abuse by consumers. The intent presumably being to aid in determining the validity of warranty claims. 'Consumer abuse events' would be recorded by liquid and thermal sensors detecting extreme environmental exposures, a shock sensor detecting drops or other impacts, and a continuity sensor to detect jailbreaking or other tampering. The article also notes that liquid submersion detectors are already deployed in MacBook Pros, iPhones and iPods. It does seem reasonable that a corporation would wish to protect itself from fraudulent warranty claims; however the idea of sensors inside your portable devices detecting what you do with them might raise eyebrows even beyond the tinfoil-hat community."

AMD has created and released the industry's first OpenCL which allows developers to code against AMD's graphics API (normally only used for their GPUs) and run it on any x86 CPU. Now, as a developer, you can divide the workload between the two as you see fit instead of having to commit to either GPU or CPU. Ars has more details."

Windows Drains MacBook's Battery; Who's To Blame? 396

ericatcw writes "Users hoping that Windows 7's arrival will mean less power drain on their MacBook laptops may be disappointed, writes Computerworld's Eric Lai. Running Windows 7 in Boot Camp caused one CNET reviewer's battery life to fall by more than two-thirds. But virtualization software such as VMware Fusion suffer from the same complaints. Some blame Apple's Boot Camp drivers (the last ones were released in April 2008); others lay the blame at Windows' bloated codebase. With Apple and Microsoft both trying to avoid responsibility for improving the experience, Windows 7's reported improvements in power management will be moot for MacBook users for a while."

DIY CPU Thermal Grease, Using Diamond Dust 210

tygerstripes writes "The dysfunctor has spotted an impressive project over on InventGeek.com; an innovative chap has developed his own thermal compound for improved CPU cooling, using diamond dust — the best available material for thermal conduction — as the key ingredient. In spite of the quick-&-dirty DIY nature of the project, the gains in cooling performance are remarkable, especially considering the material cost was only $33. Given the price many enthusiasts will pay for a top-end cooler, it's easy to imagine this product coming to market quite soon."

Mind-Blowing Interfaces On Display At SIGGRAPH 2009 173

An anonymous reader writes "Tech Review has a roundup of some cool, experimental new interfaces being shown at SIGGRAPH 2009, underway in New Orleans this week. They include an amazing 'touchable holograph' display, developed by a team in Japan, which uses an ultrasound device to simulate the sense of touch as the user grasps objects shown in 3D. The other ideas on display are Augmented Reality for Ordinary Toys, Hyper-Realistic Virtual Reality, 3D Teleconferencing and Scratchable Input Devices. If this is the future of computers, sign me up." The conference has also seen the release of OpenGL 3.2 by the Khronos Group.

Navigating a Geek Marriage? 1146

JoeLinux writes "I am soon to marry my true love (a girl! yes! they do exist!). She is a literary geek, whereas I am a gaming/Linux geek. Being the RTFM-style geeks that we are, we have been reading up on marriage, making things work, etc. Unfortunately, all of the references seem to be based around an alpha-male jock and a submissive cheerleader-style wife. A lot of the references to incompatibility in the books don't apply to us (neglect due to interest in sports, etc.). What are some of the pitfalls and successes learned in the course of a more geek-oriented marriage?"

11.6" Netbooks Face Off 238

Dr. Damage writes "Netbooks have grown from tiny curiosities with 7" screens into surprisingly well-rounded little computers. The latest step is 11.6" displays with 1366x768 resolution and near-full-sized keyboards. Two such systems are available now for under $400 at US retailers: the Aspire One at Walmart and the Gateway LT3103 at Best Buy. The Gateway packs an Athlon 64 processor and Radeon graphics. The Tech Report bought them both and has compared them head to head in some depth, choosing a clear winner between the two." Like most such in-depth reviews, this one is spread across 10 pages.

California Student Arrested For Console Hacking 1016

jhoger writes "Matthew Crippen was arrested yesterday for hacking game consoles (for profit) in violation of the Digital Millennium Copyright Act. He was released on a $5,000 bond, but faces up to 10 years in prison. This is terribly disturbing to me; a man could lose 10 years of his freedom for providing the service of altering hardware. He could well lose much of his freedom for providing a modicum of it to others. There is no piracy going on, necessarily — the games a modified console could run may simply not be signed by the vendor. It's much like jailbreaking an iPhone. But it seems because he is disabling a 'circumvention device' it is a criminal issue. Guess it's time to kick a few dollars over to the EFF."

Intel Confirms Data Corruption Bug, Halts New SSDs 137

CWmike writes "Intel has confirmed that its new consumer-class X25-M and X18-M solid state-disk drives (SSDs) suffer from data corruption issues and said it has pulled back shipments to resellers. The X25-M (2.5-inch) and X18-M (1.8-inch) SSDs are based on a joint venture with Micron and used that company's 34-nanometer lithography technology. That process allows for a denser, higher capacity product that brings with it a lower price tag than Intel's previous offerings, which were based on 50-nanometer lithography technology. Intel says the data corruption problem occurs only if a user sets up a BIOS password on the 34-nanometer SSD, then disables or changes the password and reboots the computer. When that happens, the SSD becomes inoperable and the data on it is irretrievable. This is not the first time Intel's X25-M and X18-M SSDs have suffered from firmware bugs. The company's first generation of drives suffered from fragmentation issues resulting in performance degradation over time. Intel issued a firmware upgrade as a fix."

Breakthrough in Electricity-Producing Microbe 177

University of Massachusetts researchers have made a breakthrough with "Geobacter," a microbe that produces electric current from mud and wastewater. A conservative estimate puts the energy output increase at eight times that of the original organism, potentially allowing applications far beyond that of extracting electricity from mud. "Now, planning can move forward to design microbial fuel cells that convert waste water and renewable biomass to electricity, treat a single home's waste while producing localized power (especially attractive in developing countries), power mobile electronics, vehicles and implanted medical devices, and drive bioremediation of contaminated environments."

Carmack & Mustaine Talk Doom Resurrection For the iPhone 57

themacgamer writes "Luis Sosa had a chance to sit down with John Carmack and Tom Mustaine of id Software and discuss Doom Resurrection for the iPhone: 'At the start we thought it was just a touch screen, so you'd tap to shoot the monsters, but it was never fun; it felt too clinical. It didn't feel like you were swinging your heavy gun around to bring down the monster before he chews off your head,' said Carmack. Mustaine added, '[The shooting mechanic] was definitely a trial-and-error thing. You said the word "distilled," and that's definitely a word we've been using. We really wanted to distill the visceral Doom experience into the iPhone.' He also said, '... we have P2P co-op play that's not in the shipping version, but will come later. We didn't expect the 3.0 OS out so quickly! Two players join together, they see each other's cursors, and they either compete or co-op for a score. We're hoping to patch it in down the road. We're also looking at additional levels and potentially some stat-tracking stuff as well.'"
