These days it seems like “nanotube” is sort of a magic word. Scientists will say something crazy like “We’re building an elevator to space” and everyone else asks “How you gonna do that, scientists?” and they just say “carbon nanotubes,” and we’re like “oh, cool.” So go ahead and guess how scientists have created a kind of paper that’s 500 times as strong as steel and only weighs a tenth as much.
That’s right, it’s nanotubes. The paper, called “buckypaper,” is flexible in single sheets, and can be layered to form rigid plates. It’s being rapidly developed for commercial production, for use in everything from armor to laptops to fuel cells.
Ben Wang, one of the professors leading the charge to commercialize buckypaper, explains that the strength of the paper comes from nanotubes’ enormous surface area, saying “If you take a gram of nanotubes, just one gram, and if you unfold every tube into a graphite sheet, you can cover about two-thirds of a football field.”
What do you all think? How might we use this super-strong paper in the future? Hit the jump and let us know.
Everyone's heard of Linux, right? We wouldn't be wrong in suggesting that Linux is the most well-known representation of the open-source platform. Or, at least, we're willing to bet that it's going to be on the tip of your friend's tongue the next time you sit down at bar, order up a drink, and ask, "What's an example of Open Source?"
But we think you'd spit out your drink if your friend answered "Chumby," or "RepRap." You might even try calling out your buddy because you think he's just feeding you jibber-jabber to sound smart. Well, you'd be wrong to do so. These are indeed open-source creations, but you aren't going to find these projects no matter how much you scour SourceForge. That's because they're examples of open-source hardware, not software. That's right. The concept of throwing back the curtain and revealing all the working pieces of a particular item for you to modify at your leisure isn't an act that's constrained to bits and bytes.
Click the jump, and we'll show you the Open Source hardware projects you can make right now!
ASUS CEO Jerry Shen discussed the Eee PC range at great length during an interview given to Laptop Magazine. He pegged all-time Eee PC sales – it has just completed its first year in the market - at around 4 million units. Shen confirmed rumors that the first batch of touch panel Eee PCs will become available by early 2009, but withheld details of the touch-sensitive netbooks.
He disclosed that the 7-inch Eee PC has performed very well till now. Shen rejected the possibility of an Eee PC with a screen size in excess of 10 inches. He argued against the notion that its Eee PC range has pushed all its other notebooks to the background. Finally, Shen said that Eee PCs running Windows 7 will become available in mid-2009.
For the past few weeks we have presented you with our $1500 Budget Badass and $2500 Power User PC. This week we’re bringing to the table our picks for a $2500 Pro Gaming PC. With significant price cuts since our last Pro Gaming PC build-it guide, we were able to give our gaming PC some extra juice so system lag can no longer be blamed for missing a crucial headshot. Many parts have not changed since the last update, but with new hardware technology coming soon to the computer industry, be prepared for some significant tweaks next month. But for now, here’s what we got.
Would you build it differently? If so, we would love to hear how you would do it in the comments!
The device includes a 312MHz Marvell PXA270 processor, Linux 2.4.19, full QWERTY/AZERTY keyboard, an 8GB SD card slot ,Opera Mini 4.1 internet browser and 2.8 inch screen. The iKIT has inbuilt WiFi and Bluetooth capabilities, and supports HSDPA over USB. It has a standby time of 250 hours and power-up time of up to 3 hours.
The suggested retail price of roughly $170 makes it far more affordable than an Apple iPhone – a fact specifically called to attention by IMOVIO. However, practicality of such a product is just as important as the price, if not more, and will play a vital role in iKIT’s case as well.
And now, a whole new way for your privacy to be invaded. Computer scientists at the EPFL in Switzerland have developed a way to eavesdrop on what you type by detecting the electromagnetic radiation emitted with every keystroke, Engadget reports.
The group developed four techniques for listening in on keystrokes, and tested them on 11 keyboards, produced from 2001 to 2008 and including USB, PS/2 and laptop keyboards. Every one of the devices was vulnerable to at least one of the methods. Some of the techniques are effective from as far away as 65 feet, and through walls.
Martin Vuagnoux, one of the scientists responsible, has posted twovideos demonstrating the vulnerability on Vimeo. The first of the two videos shows a meter-long wire being used as an antenna to detect the emissions of a keyboard several feet away. A program successfully decodes the message “trust no one” from these emissions. The second video shows an antenna that looks a bit like a pair of gigantic egg beaters eavesdropping on a keyboard from one room over.
The technique is pretty cool to see in motion (if a bit scary) so check out those videos and hit the jump to give us your thoughts.
Starting on October 19, 2008 Intel Core 2 Quad Q8200 and Q6600 will be priced at $193 and $183, drops of 14 percent and 5 percent respectively. The only question you’ve got to ask yourself is whether or not you want a chip with two cores and a higher clock or four cores with a lower clock.
The price on the Intel E7300 has gone from an already low $133 to $113, wih the E2220 and the E2200’s following suit dropping to $74 and $64,
At this rate, you’ll be able to build a rig for almost nothing!
Thanks to everybody’s favorite economy, the prices of large-size LCD monitors are on the way down again. After stabilizing for about a month, a lower than expected demand is putting pressure on monitor vendors to drop their prices.
After October prices are expected to drop 5-7%, with that trend continuing in the future. Large financial challenges are expected for the fourth quarter of 2008.
So if you’ve been waiting around to pick up a fancy 30” display, just wait a bit longer and you’ll get the price you’ve always wanted! If you’ve already picked up a 30” display, why not snag another? If you’ve already got three 30” displays, then Al Gore, I’m going to have to ask you to get back to work, sir.
A Google Apps malfunction was reported on Thursday leaving education edition users without access to various services, including Gmail. It turns out the loss of access was tied to an unannounced change in the layouts of start pages which redirected to a non functional iGoogle address. Google spokesmen Andrew Kovacs stated that "this was an isolated bug". "I don't want to minimize this, but was this an issue where people could not access their data? No." Google hasn’t publically stated how many of the over one million businesses and 10 million users were impacted by the bug, but apparently it was only reported by a handful of users. Kovacs went on to state that "Basically, the broader perspective with an approach to communication is to be transparent. With these hosted applications we are held to a higher standard since we are so transparent with our communication." This made me wonder. With all the negative back lash companies like Google, Microsoft, and Amazon receive when cloud services crash, is all the bad press really fair? Do we really have the right to expect 100% uptime?
Intel claims that the X25E can increase the performance of servers, workstations, and storage systems by 100 times over hard drives, if measured in terms of Input/Output per Second (IOPS).
The 32GB SSD, which Intel claims can reduce energy costs by five times, boasts of 35,000 read IOPS and 3,300 write IOPS. The official press release pegged the maximum read speed at 250 MB/s and maximum write speeds at 170 MB/s respectively.
The 32GB version is out now and carries a price tag of $695. The production of the 64GB version will begin in first quarter of 2009.
