Apple iPods now come with viruses

Apple says the virus infected only the video iPod and not the Nano or any of the Apple computers. The iPods were infected by a Windows machine at a contract factory. An official statement and apology was posted to Apple's website and you can view that here.Apple is placing some of the blame on the Windows operating system and said, "As you might imagine, we are upset at Windows for not being more hardy against such viruses, and even more upset with ourselves for not catching it." The RavMonE virus doesn't cause any serious damage or data loss, but it does act as a trojan horse that could allow other, more serious, viruses to infect the computer. The offending computer has been found and dealt with and Apple says it doesn't expect any more infected iPods to be produced.

Element 118 Created, Scientists Report

2006-10-18T16:14:00.000+05:30

A U.S.-Russian team is seeking even heavier atoms in a theoretical `island of stability.'

A U.S. and Russian team said Monday that it had created element 118, the heaviest known to date.

It is the fifth ultra-heavy element produced by the team at Lawrence Livermore National Laboratory and the Joint Institute for Nuclear Research in Dubna, Russia, which has come to dominate the creation of short-lived elements.

Although they produced only three atoms of element 118, and each lasted for less than a thousandth of a second, the team said that there is less than one chance in 10,000 of mistaken identity.

A team at Lawrence Berkeley National Laboratory announced in 1999 that they had created element 118 by a different route, but those results were shown to have been fabricated by physicist Victor Ninov, who was eventually fired by Berkeley.

"We selected a completely different nuclear reaction, performed with completely different people in a different laboratory," said physicist Ken Moody of Livermore, who led the American team, at a Monday news conference. "Everything we do is checked and double-checked."

Their findings will be published today in the journal Physical Review C.

The discovery has no immediate application, but brings researchers closer to discovering what theoretical physicists have described as an "island of stability" — a group of ultra-heavy elements that may survive minutes, or even hours, compared to the fractions of a second now seen with the heaviest creations.

That would allow researchers time to begin to understand the chemistry of the elements, perhaps even to discover some unique new chemical properties.

"I think of this like any other journey to a new place," said physicist Nancy Stoyer, a member of the Livermore team. "Finding it is something new, something interesting. At some point, we will no longer be able to discover new elements. We will reach the end of what we can find."

The team used a cyclotron at Dubna to bombard the man-made element californium-249 with ions of calcium-48.

In two separate experiments, they bombarded the target with 40,000,000,000,000,000,000 ions, producing three atoms of element 118. Each atom had 118 protons and 179 neutrons in its nucleus, giving it an atomic weight of 297.

The element was characterized by observing its radioactive disintegration. Each atom first spit out an alpha particle — composed of two protons and two neutrons — to become the previously known element 116. That element, in turn, spit out another alpha particle to become element 114, and then another to become element 112. Element 112 fissioned into two atoms of roughly equal size.

Element 118 would fall directly below radon in the periodic table of the elements and is thus expected to be a so-called noble gas.

Only 92 elements exist in nature, but physicists have produced 18 more that have been officially recognized and named.

The Livermore-Dubna team has also created elements 113, 114, 115 and 116, but none of those has yet been officially recognized, named and placed in the periodic table because the work has not been replicated by other researchers.

The team will now try to produce element 120 by bombarding a plutonium target with a beam of iron ions.

Heavier elements will require the construction of a new accelerator, the Rare Isotope Accelerator.

But work on that accelerator, which will be built at either Michigan State University or the Argonne National Laboratory in Illinois, has been delayed by lack of funding.

Software revises Armstrong's moon quote

That's one small word for astronaut Neil Armstrong, one giant revision for grammar sticklers everywhere.

An Australian computer programmer says he found the missing "a" from Armstrong's famous first words from the moon in 1969, when the world heard the phrase, "That's one small step for man, one giant leap for mankind."

The story was reported in Saturday's editions of the Houston Chronicle.

Some historians and critics have dogged Armstrong for not saying the more dramatic and grammatically correct, "One small step for a man ..." in the version he transmitted to NASA's Mission Control. Without the missing "a," Armstrong essentially said, "One small step for mankind, one giant leap for mankind."

The famous astronaut has maintained he intended to say it properly and believes he did. Thanks to some high-tech sound-editing software, computer programmer Peter Shann Ford might have proved Armstrong right.

Ford said he downloaded the audio recording of Armstrong's words from a NASA Web site and analyzed the statement with software that allows disabled people to communicate through computers using their nerve impulses.

In a graphical representation of the famous phrase, Ford said he found evidence that the missing "a" was spoken and transmitted to NASA.

"I have reviewed the data and Peter Ford's analysis of it, and I find the technology interesting and useful," Armstrong said in a statement. "I also find his conclusion persuasive. Persuasive is the appropriate word."

SketchUp: Google's Latest Cool Free Download

SketchUp, a 3D drawing application which Google released today, is the latest example of a happy, booming software trend: Google or Yahoo buys an innovative small company which makes a for-pay product, and quickly releases a cool free version of its software.

In this case, the innovative company was @Last Software, and SketchUp truly is cool, since it makes the notoriously difficult job of drawing 3D architectural models surprisingly easy. In its Google iteration, it's a complement to Google Earth, one which lets that amazing program's community of fans build and share buildings to be incorporated into its virtual world.

The application comes with bountiful documentation and tutorials, but the user interface is simple and intuitive.

But you can have fun with SketchUp without constructing anything from scratch, because it's easy to grab models from Google's 3D Warehouse, a searchable online repository of objects, including excellent recreations of lots of real-world landmarks. (You can also upload your creations to the Warehouse.) Here's one example of a ready-made model:

And here's San Francisco's AT&T Park (nee SBC Park, nee Pacific Bell park) as it looks after being imported into SketchUp:

This is not a review of SketchUp. SketchUp is about the least intimidating one ever seen. Which makes Google an entirely appropriate home for it.

As with Google Earth, by the way, there's still an industrial-strength version of SketchUp aimed at professionals, at an industrial-strength pricetag: $495. The free version is Windows-only at the moment, but a Mac edition is on the way.

Scientists create artificial insect's eye

Scientists at the University of California, Berkeley, said on Thursday that they have created anew mechanical eye, which looks and works like an insect's eye.The eye's many lenses and curved shape give it a wide field of view, as well as super-fast motion detection and image recognition, the researchers reported in the April 28 issue of the journal Science.

Minute cameras and motion sensors with these types of lenses could have medical, industrial and military applications, according to the researchers.

Insects have multiple imaging units called "ommatidia" that are pointed in different directions. The researchers used flexible polymers to build artificial ommatidia, each with a tiny lens connected to a tube-like "waveguide" that directs the light down to an opt electronic imaging device.

Then, they arranged the ommatidia around a dome, projecting outwards in all directions. Of the many different types of insect eyes, a bee's eye is most similar to the new mechanical eye, they said.

Just like pins in a pincushion or a dragonfly's 30,000 ommatidia, the team's artificial ommatidia are each oriented at a slightly different angle. The researchers have shown that the lenses and waveguides of the artificial eyes focus and conduct light in the same way as an insect's eye.

"The lenses and waveguides are the most important part of the system," said Luke Lee, the principal investigator of the study.

"People have said that it would be totally impossible to create them with an angle, but now that we've done it, we're ready to integrate imaging or chemical sensing into the eyes," Lee said.

While conventional micro fabrication techniques are expensive and use high temperatures, Lee and his team borrowed from nature, using a low temperature system, photopolymerization, and self-aligning, self-writing technology.

To create the artificial eye, the team first needed to construct a hemispherical mold of the eye's outer layer, a structure consisting of thousands of microlenses.

Using existing technology, they made a flat array of these tiny,domed lenses arranged in the hexagonal honeycomb pattern. On top of this, they applied a thin slab of an elastic polymer called polydimethylsiloxane, or PDMS, creating a concave pattern of the lenses in the polymer.

By affixing the PDMS membrane over the opening of a vacuum chamber and applying negative air pressure, they pulled it into the dome shapes they needed, controlling its form by using different pressures.
These eyes can eventually be used as cameras or sensory detectors to capture visual or chemical information from a wider field of vision than previously possible, even with the best fish-eye lens, according to Lee.

The researchers speculate that the artificial compound eyes will be put to use within a few years. Their first applications may be in ultra-thin camera phones, and then in camcorders for omnidirectional surveillance imaging and such uses as small, hidden, wearable cameras.

Yahoo! Gives Babel Fish a New Bowl

Good old Babel Fish, the "mascot, star, and proprietor of the oldest free, on-line translation service on the web" has a new home. He has leapt from his original bowl over at Alta Vista over to Yahoo!

Go to babelfish.yahoo.com and type most anything you'd like to translate (phrases or passages under 150 words or a Web page), and Babel Fish takes care of the rest. I punched in "I really like to eat fish" in English, scrolled down the dropdown menu to my language of choice, Spanish, and got back "Realmente tengo gusto de comer pescados." Not bad.

New enhancements attained over at Yahoo! include a couple of new languages (simplified Chinese into traditional Chinese, and traditional Chinese into simplified Chinese), bringing the site's total to 38 language pairs you can translate between. You'll also find a Babel Fish toolbar button as well as tighter integration between translation and Yahoo! search services, among a few other things.

Green Machine

60mph green machine may be the answer to city traffic jams

This three-wheeled vehicle, part-motorbike and part-car, is being hailed as the future of city driving. Called the Clever, it is half the width of a conventional car, can carry a passenger and, as it runs on gas, would be exempt from the congestion charge in London.
NI_MPU('middle');
It does more than 100 miles (160km) per gallon, three times that of most cars, and emits a third less carbon dioxide. The EU-funded project involved a team from the University of Bath, where it was showcased yesterday. The Clever has a top speed of 60mph and will cost from £5,000 to £10,000 if it makes it into production. The Clever had been successfully crash-tested. Next step is to get EU funding to create a batch of 100 of the vehicles for trial in European cities.

Black holes generate ‘green’ energy

2006-04-26T09:32:00.000+05:30

A new study finds that the supermassive black holes at the hearts of some galaxies are the most fuel-efficient engines in the universe. "If you could make a car engine that was as efficient as one of these black holes, you could get about a billion miles out of a gallon of gas," said study team leader Steve Allen of the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University. "In anyone's book, that would be pretty green." The finding, made using NASA’s Chandra X-ray Observatory and announced in a media teleconference Monday, is giving scientists insights into how supermassive black holes generate energy and how they affect the galaxies where they make their homes.ad_dap(250,300,'&PG=NBCSAT&amp;AP=1089');Black holes are regions of space where gravity is so strong that matter and light can't escape from within the event horizon, a spherical boundary surrounding the black hole.However, inflowing matter that hasn't yet passed this point of no return can — through friction and interaction with the black hole's strong magnetic field — release energy in the form of either diffuse light or focused jets of energy."Once gas comes within a distance about a million times larger than the event horizon of the black hole, it becomes gravitationally captured," Allen explained. "At this point the gas becomes fuel for the black hole engine."The new study looked at nine supermassive black holes at the centers of elliptical galaxies. Each one was about a billion times more massive than our sun. The black holes were relatively old and generated much less energy than the fiercely luminous and rapidly growing supermassive black holes known as quasars.The researchers found that these "quiet" black holes released about 1,000 times more energy as jets than as diffuse light. The reasons for this are still unclear."That's a mystery, how these black holes selectively put that much energy into the jets without producing much light," study team member Christopher Reynolds from the University of Maryland told Space.com.Space bubbles
Most of the energy in the jets is being emitted as radio waves, but in at least one of the black holes studied, the energy was in the form of more energetic X-rays."The energy in these jets is absolutely huge, about a trillion trillion trillion watts," Allen said.

As they race outwards from their parent black holes at nearly light speed, the jets carve out enormous cavities, or "bubbles," in the surrounding gas environment; some of these bubbles can be tens of thousands of light years across.Bubbles can also form in the aftermath of stellar explosions called supernovae; our own solar system is enveloped by such a structure, called the "Local Bubble," which was formed during an explosion long ago.The researchers used these bubbles to figure out the fuel efficiency of the black holes. Using Chandra images, they first calculated how much fuel in the form of gas was available to each black hole. They then estimated the power required to produce the bubbles that were observed.Preventing galactic sprawl
The finding could have implications for other types of black holes as well, including much smaller, stellar-mass black holes, the researchers say."We already knew that powerful quasars are very efficient at making light. Now we know that black holes in elliptical galaxies are efficient as well," said Kim Weaver, a researcher at NASA's Goddard Space Flight Center who was not involved in the study. "This suggests that being green is a trait that all black holes may have in common."The scientists think the supermassive black holes are green in another way, too. The energy that each black hole emits as jets warms the surrounding environment. This prevents gas from cooling and coalescing into billions of new stars, and places an upper limit on how large a galaxy can grow."In an environmental sense, the black holes are actually preventing galactic sprawl from taking over the neighborhood," Weaver said.

750GB drive

Seagate's 750GB drive

The existence of the 750GB from Seagate, although not yet official, proves that the quest for ever larger storage spaces is never-ending.

Likely to target the desktop drive market, I would think that the problem with such a large single drive is the possibility for failure. 750GB is a lot to lose from a single hardware fault.

As users - home, work and otherwise - we are now storing much more data than ever before. Our music collection, digital photos, even home videos are a prime source of data space in the home, and sometimes at work. For the business desktop it is applications, raw data (photos, spreadsheets and analysis output from databases) and for some more complex types, like virtual machine hard drives and others.

With 750GB you would be tempted to store a lot more, but a hardware failure (and it will happen) could wipe out parts of your entire life and existence. Imagine how upset you would be if you lost the only photos you had of your son, daughter or pet? At work, imagine losing all the work on a large project.

Backups, of course, are part of the answer, but any serious user would also be using a RAID solution - probably RAID 5 - to ensure that a failure didn't cause a blip in operation.

I can't help thinking that with such high drive densities (they are expecting 1GB before the end of 2006) that a better solution would be to look at a new format, perhaps one that combined three slim-line drives of, say, 300GB each and embedded a RAID 5 controller. Each individual drive would be replaceable, but the whole unit would be sold as a kit. You could probably make it about full-height, 3.5" in size, but you'd have a large, and reliable, 'single' drive for storing your data.

Cheap, affordable, easy to build, include and configure RAID for the small business and home market would be a massive boon, and you could still approach the sort of capacities people are looking for, while providing it in a reliable package.

Meanwhile, for those of us who know what we are doing, 750GB will help to reduce power requirements, cooling requirements and physical space. Time, perhaps, to think about replacing the current 6 drive/1.25TB solution, either with something physically smaller and larger capacity, or the same physical size and much larger capacity.

usb battery

2006-04-21T19:28:00.000+05:30

how-to: ‘usb battery’ v2

quick improvement

As mentioned by several readers, you’ll want to use a 5 volt regulator ic instead of the resistor/zener-diode combo i discussed previously. you’ll be able to charge your device faster while it is running and it’s much more efficient, which will give your 9 volt a longer battery life.

the best part is that it’s easier and cheaper to do it this way. just grab an lm7805 from your local hacker store and wire it up. connect the positive battery terminal to the 7805 input pin, the positive usb pin to the 7805 output pin, and connect the negative battery terminal and the usb ground pin to the 7805 ground pin.

which is which? if you hold the 7805 with the text facing you and the pins downward, the pins from left to right are: input, ground, output. it looks like this:

for the female usb connector, look down into the end of the connector so that it is oriented like so:

pin 1 is the positive (5v) terminal (which goes to the output of the 7805) and pin 4 is ground (which goes to the 7805 ground pin).

easiest way to test

several people were wondering how to tell if you are going to fry your device. here’s the easiest way to test when you are all done wiring:

cut a standard usb cable in half.
plug the male end into your usb battery.
connect the positive and negative ends of your multimeter to the red and black usb wires respectively.
if it reads something very close to 5v then you are wired correctly.

making a case

chose to make my case out of polystyrene plastic. you can find this stuff in sheet form at most hobby stores. it’s the same kind of plastic used in your standard plastic model kit and the sheet form lends itself nicely to making flat sided objects… like a small case for a usb battery!

basically, you can just cut the sheet to the size you want with an x-acto knife. then, just glue them together carefully with standard issue model cement. the cement is a polystyrene solvent and it melts the connected peices of plastic together. when you are finished with the basic assembly, use a sheet of 400 grit sandpaper to smooth the sides down and bevel the edges.

room with a view

here you can see the case during construction. i want it to be small, so i sized it just large enough to accommodate the battery and usb connector.

regarding the usb connector. metal can be notoriosly hard to secure to plastic. model cement works best for styrene on styrene, but 2 part epoxy or super glue seem to do the best job for syrene on metal. try to affix the largest possible surface area. i glued small pieces of styrene to each of the 4 faces of the usb connector. you can then cement on more styrene to build up a larger surface area which can then be securely affixed to the front of the case.

sliding door

to close off the battery compartment, i made a pretty simple sliding door. it’s just two pieces of styrene with a third smaller piece sandwiched in between. this slides on rails which were made by cementing thin strips of styrene to the case.

where to go from here

Hackers load Linux onto Intel Mac

Hackers who came up with a way of dual-booting Mac OS X and Windows XP on an Intel-based Mac before Apple introduced Boot Camp have now made it possible to add Linux to the mix.
The OnMac.net project has published instructions on how to triple-boot Mac OS X, Windows XP and Linux using Apple's Boot Camp utility.The procedure has been successfully used to set up a MacBook Pro, but is as yet untested on the iMac and Mac mini models.The actual process itself is pretty tricky, as it is not possible to boot Linux from Boot Camp. The open source OS would have to be 'chain loaded' from an installed copy of XP using the LILO bootloader.Although OnMac.net was created earlier this year with the intention of finding a way to boot Windows on an Intel Mac, a quest that was superseded soon after it was completed by Apple's launch of Boot Camp, the site founders are maintaining the site for new projects such as the triple-boot idea.Full instructions for triple-booting can be found at Triple Boot via BootCamp

Supercomputer simulates black hole collision

Supercomputer simulates black hole

Supercomputer simulates black hole collision

When two black holes collide, space shivers like Jell-O. With the help of a supercomputer to simulate this event, NASA seeks to prove Albert Einstein's theories and unveil universe's secrets.

The NASA supercomputer Columbia just performed its largest astrophysical calculation ever; a 3D simulation of two black holes merging. "This merger is a cataclysmic event, second only to the Big Bang in the amount of energy it produces," Joan Centrella, chief of the NASA Gravitational Astrophysics Laboratory in Greenbelt, Md., said Tuesday in a press teleconference.

NASA called the successful simulation a breakthrough in the observation of black holes, as well as the understanding of the entire universe. In fact, NASA claims that it might even provide the ultimate proof for Einstein's theory of general relativity.

Black holes occur when large stars burn up all their energy and collapse into bodies of enormous density. Their gravity is so strong that it absorbs everything around them--even light.

When two of these bodies collide, they emit more energy than the light of all the stars in the universe combined. Space shivers like a bowl of Jell-O around them, when gravitational waves spread at light speed. It is the pattern of these waves that NASA has now managed to simulate.

"Gravitational waves are going to give us an entirely new window on the universe," said Peter Saulson, a physics professor at Syracuse University involved in the project. He compared the results with the discovery of radio waves, infrared light and x-rays.

"Each time astronomers were able to open a new window, the universe showed a new face," he said. "Now that we are about to open up the gravitational wave window, we should again see a whole new different view of the universe."

Obstacle overcame
Einstein explored the forces of gravity in his general relativity theory, predicting phenomena like black holes and gravitational radiation long before they could be proved. It is not until now, more than 90 years later, that scientists have managed to test these, back then inconceivable, predictions, Centrella said. "This has been a holy grail quest for the last 30 years."

Earlier trials failed since the equations based on Einstein's general relativity theory were so complicated that they made supercomputers crash; the enormous gravity of black holes cause disturbances in time and space, making time stop and space shrink and expand.

NASA researchers have managed to transform the theory into mathematical algorithms and run through it through Columbia, thefourth most powerful supercomputer in the world. Its 2,032 interconnected 512 Intel Itanium 2 processors ran for 80 hours, in an operation that would have taken 18 years for a single processor to perform.

The result was a model of the gravitational wave pattern of the black hole collision, which turned out to be the same disregarding the bodies' starting positions. Knowing the pattern, scientists can look for and interpret it in space, Centrella said.

"This is not something made up, like in a science-fiction movie," Centrella said. "We have confidence that these results are the real deal, that we have the true gravitational fingerprint predicted by Einstein for the black hole merger."

In fact, scientists are already out there looking. The National Science Foundation's Laser Interferometer Gravitational Wave Observatory (LIGO) in Hanford, Wash., is scanning space for the waves. Now they know what to look for, said Paul Hertz, chief scientist at NASA headquarters in Washington, D.C.

"Today we're throwing down the gauntlet for Einstein's theory of general relativity," Hertz said. "When LIGO detects gravitational waves from merging black holes, we will know whether Einstein's theory is right, or whether Einstein's theory is wrong."

Google Voice Search

Google look to voice search

Search engine giant, Google, has prompted speculation about the future of voice-based search following its acquisition of patent 7,027,987, Voice interface for a search engine. While Google has not offered an official comment on the technology yet, the patent's abstract on the US Patent Office database indicates that voice recognition technology would be utilised to perform a search query in much the same way as the text based service works at the moment. The abstract describes how: 'The system receives a voice search query from a user, derives one or more recognition hypotheses, each being associated with a weight, from the voice search query, and constructs a weighted boolean query using the recognition hypotheses.' The Boolean search allows users to create a refined search by constructing logical relationships between terms to widen or delimit the results, typical Boolean terms are or, and or not.

Microsoft Launches Competitor To Google Scholar

The beta version of Windows Live Academic Search lets users search the Web for journal articles, academic papers, and notes and slides from scholarly conferences.

Microsoft Corp. introduced a new search engine for academic journals late Tuesday.

The beta version of Windows Live Academic Search lets users search the Web for journal articles, academic papers, and notes and slides from scholarly conferences in computer science, electrical engineering and physics.

The search effort between Academic Search, industry association CrossRef and more than 10 publishers connect users to primary research material. CrossRef, a nonprofit group, operates a citation-linking platform allowing researchers to legally access millions of articles and other content from several hundred scholarly and professional publishers.

Academic Search will source journals from the Association for Computing Machinery, Institute of Electrical and Electronics Engineers, Reed Elsevier and Wiley & Sons. Reading more than the abstract, however, requires a subscription. The initial beta for the service is available in the United States, the United Kingdom, Germany, Italy, Spain, Japan and Australia.

The tool for researchers, students, librarians, and journalists narrows searches to specific interests. There are plans to add journals from medicine, psychology, history and art in phases following the initial launch.

Academic Search supports OpenURL, the library standard used for linking to subscription-based content via the Web, and Open Architecture Initiative (OAI) protocol to index OAI-compliant repositories. For example, Microsoft has indexed the content in ArXiv.org. Microsoft also provides a list of the journals and source indexes. Functions also include the OpenURL standard to allow users to click on the link in their library Open URL to determine their access to the full text.

The site competes with Goolge Scholar and SciFinder Scholar, which cover a broad subject range.

Google Pins Hopes on Calendar

For all of the hoopla surrounding Google's products, the company sure has struggled to generate smash hits outside of Web search. Sure, Google's maps, with their eye-catching satellite imagery, have been a scorching success. But many other ventures, from shopping site Froogle to social networking hub Orkut to Google Talk instant-messaging client, have generated little enthusiasm.

The company hopes to better the record on Apr. 13 when it launches Google Calendar -- a free, Internet-based calendar that helps users keep track of important dates, events, and information.

Early indications are promising. Several analysts who have tried the product believe Google may be on to something. Google Calendar differs from most other online calendar services because it lets users publish and share the information, as well as overlay events from other calendars.

SYNCED SCHEDULES. Google Calendar users, for example, could sync their own calendars with those of a spouse and children to more efficiently plan a summer vacation. "Our goal is to reduce the burden of running a calendar," says Google Product Manager Carl Sjogreen.

That may be just the start. Google's goal is to make this not just an end product, but rather a platform for organizing events and sharing information, analysts say. "Google has rethought the entire role of a calendar," says Forrester Research analyst Charlene Li. "It recognizes you have several calendars to manage and that you have to interact between them."

Calendar could thrust Google into other new areas, including territory occupied by the likes of Evite, owned by Barry Diller's IAC/InterActiveCorp . Google Calendar lets users plan events, including sending out invitations and reminders, keeping track of RSVPs, and interacting with potential guests.

ADS FOR EVENTS. Although Google has not announced how it plans to make money from the calendar offering, event planning could provide prime real estate for advertisers. A local costume store could advertise in conjunction with an invitation for a Halloween party, for instance. "Events are highly monetizable," says Li.

LCD Window Case

It used to be that the true measure of a computer geek was what they had done to mod their system. One of the more challenging mods was the infamous (more than famous) window kit. Using some Lexan and aquarium striping, the window kit was born. Well, some corporate marketing executive caught wind of this trend and decided it would be a good idea to mass market it. Nowa days its nearly impossible to get a case with out a ............................

Air Cooled Mouse Pad

2006-04-11T07:19:00.000+05:30

The idea for this project evolved out of necessity. Dan and I are both avid gamers. After a few hours of gaming with our normal high-end mouse pads you get a build up of sweat. The mouse and mouse pad becomes slippery and you start to loose your competitive advantage due to the loss of precision. While there are a couple mice on the market that have small fans in them to dry out your palm, they all have major failings in precision and accuracy. So after some thought and discussion we chose to build out our own custom mouse pad with a blower in it to suck the air down through the pad and away from the gamer’s hand. The result is astonishing!

Surf the web without logging on to Internet

Ever thought of surfing the web when you are not connected? Well, that is the latest offering from Rakesh Mathur. Mathur, who co-founded Junglee — that was later taken over by Amazon — has developed a software ‘Webaroo’ that will make this possible.

Like the Kangaroo — that is an inherent part of the company’s logo — it promises to leapfrog the net to a new era. The company on Monday launched a new free software service that enables consumers to instantly search web pages and view web sites without an Internet connection, on their handhelds and laptop computers.

Already the company has support from Acer, which also announced its intention to bundle Webaroo software in its laptop.

Webaroo, which launched its services today, issued a statement quoting Campbell Kan, head of Mobile Computing Business Unit, Acer Inc, as saying that they plan to incorporate Webaroo’s software into Acer’s mobile PCs.

Webaroo servers scour the web, analyse web pages and automatically select the subset of pages with the most content value in the least storage size. These pages are then assembled into topic specified ‘web packs’.

These webpacks can be downloaded on a laptop or a mobile phone. Once downloaded, the webpacks or web sites can be accessed anytime.

Zdnet, a premier technology portal, termed it as a new permutation in web search’’ with the general idea being to take a one million gigabyte index and compress it to 40 gigabytes.

MIT Builds Batteries with Viruses

Normally, one would associate the word virus with something negative, whether it is a malfunctioning desktop computer or a sickness. However, researchers at the Massachusetts Institute of Technology have "trained" viruses in a lab to create a miniature battery.

By manipulating a few genes within the virus, researchers were able to get the organism to grow and then assemble itself into a functional electronic device. They hope to be able to build a battery that could be as small as a grain of rice.

Two opposite electrodes -- or conductors -- form the structure of a battery, called an anode and a cathode. These are separated by something called an electrolyte, a liquid of gel-like substance that contains ions and can conduct electricity.

In the process created by MIT researchers, the viruses were engineered to create the anode by collecting cobalt oxide and gold. Since these viruses have a negative charge, they are then layered between oppositely charged synthetic polymers to create thin sheets.

Batteries made with this process could store two to three times the energy of traditional batteries that size, meaning a longer-lasting charge. While the researchers did not specify any early applications of the technology, it would likely first appear in Defense Department work. The project was funded by the Army Research Office, MIT said.

AMD schedules first 65nm processor shipments for H2 2006

AMD today said that it is on track to ship its first 65 nm processors in the second half of this year. The company claims that it already has been producing a significant number of 65nm development test chips to lay the foundation for a volume conversion of its manufacturing process by mid-2007.

AMD's first substantial 65 nm announcement was made at a press conference at the Semicon Europa 2006 event, which is currently held in Munich, Germany. Other than rumors in past days have indicated, the company did not actually demonstrate a 65 nm processor, but decided to rather reassure Semicon visitors that its silicon is stable and on schedule.

According to Dirk Meyer, AMD's president and chief operating officer, 65 nm chips have been sampling for quite a while in AMD's Fab 36 in Dresden and have been manufactured parallel to 90 nm CPUs on 300 mm wafers. While details were scarce, the company apparently is running the CPUs through its validation track, collecting and analyzing data to eliminate errors and improve production efficiency.

AMD did not announce specific processors, however there appears to be little change to previous statements that the firm's first 65 nm processors may be introduced late this year or early in 2007. The company is expected to quickly transition to 65 nm once the first wave of commercial products will have shipped. Production will be "substantially" converted to 65nm production by mid-2007, AMD said. "Our manufacturing strategy execution continues to be flawless," said Meyer in a prepared statement. "The increased capacity provided by Fab 36 will contribute to our goal of doubling total production output from 2005 through 2008."

AMD's Fab 36 is located on the same site as the 200 mm 90 nm Fab 30. The company claims that it has increased total production output at Fab 30 by approximately 80% from the first quarter of 2004 through the fourth quarter of 2005. The fab, which was originally designed to produce a maximum of 20,000 wafers per month, now produces approximately 30,000 wafers per month. Fab 36 was recently brought online and began first revenue shipments of AMD64 processors in March of this year

HOWTO: Homemade Reversing Variable-Length Extension Tube Macro

Here I will explain super cheap homemade variable length (like a bellows, sorta) reversing extension tube.

First, the technologies involved:

Reverse Lens

Lens reversing has been used as a technique for macro photography for quite a while. Decen’t close ups can be achieved by mounting the lens reverse directly on the camera, and really high magnification can be achieved by mounting the lens reverse on another (front mounted) lens. A reversed 50mm lens is basically a +10 diopter. The reason this works (I’m not a physicist, so this is a stupid explanation) is, while a lens is designed to take a large image and make it small (on your sensor), reversing it will take a small image and make it bigger.

Extension

Moving the lens farther away from the film plane increases magnification. Obviously. There are two commercial implementations of this. Extension tubes, some of which preserve the electronic connection to the lens, and bellows, which are variable length (you can contract or expand the bellows to focus and increase magnification). These are both often used with a reverse lens for added effect.

So I decided I would just make my own extension tube, and it just so happened that it ended up variable-length. I had some old diopters that were really bad so I never used them, and I had a dremel. I decided that it was possible to design a reversing extension tube with a drilled out body cap and a bunch of busted-out filters as spacers.

So what you need is:

A body cap

Some old filters that you don’t want (stackable). How much magnification you get depends on how many you use. I used 7 total, but find that 4 is the best to get good shots with. Should all be the same size and should fit the lens that you want to use.
Lens. It would probably be best to use a prime, and it can’t have an electronic aperture. You must be able to change the aperture with the ring on the lens, without it being connected to the camera. I use Nikkor 50mm/1.8D. Your lens will just attach to this mount, so you’ll still be able to use it for normal purposes after this project.

I thought of this project looking at the clearance table at Wolf, and bought 2 circular polarizers, 2 UV filters, and a body cap for a total of $12. I had a set of diopters that I never used too.

First thing to do is break all the glass out of the filters.

Do this inside a ziplock bag and one quick whack with the hammer should do it. Once the lens is fully busted shake all the broken glass down into the bottom of the ziplock bag. Dispose of the broken glass properly, make sure you don’t leave broken glass shards laying around. Do this to all the filters that you want to use. Afterwards, run water over them and clean them thoroughly with a rag. There are little tiny pieces of glass dust all in them (especially two-part rings like polarizers) and your sensor will be exposed to this if you do not clean them. This is going directly on your camera with no lens between it and the sensor, so be careful.

For turning filters, like polarizers, you don’t want to have your extension tube body turning all the time, so a dab of superglue where the two parts connect (in three or four places around the circle) should stop that problem.

Now get the lens cap and dremel out the center of it. Be sure to keep the mount in tact:

The dremel will likely melt the plastic, a bit that’s ok! makes it smoother. Sand it down. Wash all the little bits of plastic off.
Now onto the front of the body cap (that faces away from the camera), glue a filter ring, with the male side facing out. This is the side that’s going to interface with your lens. Mine wouldn’t fit on the no-name body cap that I was using so what I did was glued one male side in, and then glued another one female-female (giggidy giggidy) on top of that. So it ended up with the male side out, just using two filters. This is ok!

Now, you can either reverse mount your lens directly on the body adapter, or you can add your extra spaces to extend. This will increase magnification.

Here’s my finished extension tube and my first subject:

And here’s my first shot with it:

This picture is taken with 4 rings worth of extension.

Full manual mode only. The lens is not electronically attached so there is no metering. It’s pretty easy to get good shots with flash and the power dialed way down on it. You won’t be able to see through the viewfinder with the aperture stopped down, so what I do is open the aperture to compose, then stop it down and shoot.
Total investment: $12 + a bit of super glue. Oh and somewhere in the process I got my sensor dirty and had to clean it. So I used a little bit of compressed air too.

Microsoft backs Linux

PROPRIETARY software maker, Microsoft has told a flock of Linux users that it will provide Linux support plug-ins on Windows.
Not only that, it will make itsVirtual Server 2005 R2 available free. According to Forbe’s the sudden conversion will mean that leading Linux distributions including Red Hat Enterprise Linux 4 and Novell SuSE Linux Enterprise Server 9 will run on Virtual Server 2005.
Windows server director of product marketing Zane Adam said that the move will help help customers safely consolidate their Linux-based applications on Virtual Server.
The no-charge download was designed to break down the barriers for customers who want to adopt server virtualization, he said.
The move is seen as one of Vole’s counters to the success of IBM, Sun Microsystems, and Hewlett-Packard in getting their Linux based products onto corporate servers.

Liquid-Crystal Specs May Replace Bifocals

MONDAY, April 3 (HealthDay News) -- An eyeglass version of the liquid crystal displays used in the latest TV sets and cell phones could replace the bifocals worn by millions of older Americans, researchers report.

By applying varying electrical voltages to a thin sheet of liquid crystals between two layers of glass, it is possible to make eyeglasses that would allow the eye to immediately focus from long distances to fine print.

The pioneering devices need switches to change the way they diffract light. "But it is possible to put in a rangefinder and automatically focus the lens," said study author Guoqiang Li, an assistant professor of optical science at the University of Arizona.

"They have the potential of revolutionizing the field of presbyopia [nearsightedness] correction when combined with automatic adjustable focusing power," the report said.

The finding appears in the April 3-7 issue of the Proceedings of the National Academy of Sciences.

While procedures such as laser surgery can correct the presbyopia, many nearsighted people now wear bifocals or trifocals, which are eyeglasses with sections of varying diffractive power.

The new lenses "are basically doing the same thing, but changing automatically every time you have a different optical path," said Bernard Kippelen, who started the research effort with Li at Arizona in 2000. He is now a professor of electrical and computer engineering at Georgia Tech.

It's the same basic principle used in liquid crystal television sets and other devices, Kippelen said. An electric current applied to liquid crystal molecules can turn them on and off, he said. "We can do that within the different zones of the lens, switching them off and on with an applied voltage," he added.

The lens relies on a series of concentric rings of tiny, transparent electrodes that control the optical power of the thin layer of liquid crystals. The device operates at low voltage and can switch focal power in less than one second.

If electric power is lost, the lens reverts to a configuration with no focusing power, which makes it safe for use while driving, the researchers said.

The device described in the report was developed originally in cooperation with PixelOptics Inc., of Roanoke, Va., Li said. He estimated that a commercial product might be available "in three years or so."

PixelOptics did not immediately respond to a request for comment on its plans for developing and marketing the lenses.

A thousand processors on one chip

More than a year ago, I told you that we'll soon be able to buy kilos of processors. Today, the New York Times reports that this should be possible by mid-2007 (free reg., permanent link). Based on technology licensed from Carnegie Mellon and processors from the Power line of IBM, Rapport Inc. expects to deliver its Kilocore chips next year. Each chip will have 1,024 processors running at 125 MHz and handling 8 bits of data. But this design is particularly well suited for applications such as digital video delivered to cellphones. The company says its chip will be 50 times more efficient as current chips for such applications.

Here is the first paragraph of the New York Times article.

I.B.M. plans to announce an alliance on Tuesday with a small Silicon Valley company that has designed a flexible microprocessor chip intended to perform tasks like video processing using less than a tenth the power of today's chips.

According to the company which designed this chip, Rapport Inc., the Kilocore technology will deliver "unprecedented performance to support simultaneous multiple functions at very low power". But let's return to John Markoff's article.

The Rapport technology, known as Kilocore, will initially be aimed at portable applications like digital video delivered to cellphones. According to Mr. Singer, [Rapport's CEO,] reconfigurable logic promises better energy efficiency, which has become a watchword in large computer data centers as well.

As you can see below, the Kilocore technology is very flexible. In particular, can be upgraded in the field via software

This technology is already at work and Rapport markets a chip with 256 processors using a design licensed from Carnegie Mellon.

That approach has permitted Rapport to create a chip with 256 computing elements that can be configured on the fly to adapt to different software problems. A follow-on version of the chip will have more than 1,000 computing elements and will contain a version of I.B.M.'s Power PC microprocessor.

But will it work and be really power efficient?

At a computing conference scheduled to begin in San Jose, Calif., on Tuesday, Rapport will demonstrate the chip processing a stream of video images. While a standard industry microprocessor chip, the ARM 7, can process 3.3 images a second while consuming half a watt of power, the new Rapport chip will convert 30 frames a second while consuming only 100 milliwatts, about one-fifth the power.

The company also compares its future chip with an Intel Pentium III running at 1.8 GHz — a pretty old chip — and says the Kilocore chip will be 3 times faster but will consumes 200 times less power.

Even if this new design is really power efficient and with the help of IBM, it remains to be seen if enough applications can be adapted to such a chip to become a success on the market. In particular, applications would need to be rewritten to take advantage of the architecture, and large companies don't particularly like this exercise.

Digital TV broadcasts for mobile phones equipped with special receivers began in Japan's major urban areas Saturday, following several months of test broadcasts.

But finding new phones in stores proved hard as eager consumers have already snapped up the limited number of handsets on the market. Japan's major mobile carriers say sales are good, but have not disclosed numbers.

Japan's mobile TV service is not the world's first South Korea, Britain and several other nations offer a similar service, although with different technologies. Mobile users in some parts of the United States can also tap into digital broadcasts.

Hackers use BBC news to proliferate virus

Excerpts of BBC news are being used to lure web users to a malicious site that takes advantage of an, as yet unpatched, Internet Explorer vulnerability.

Hackers have been sending out spam emails that include snippets of BBC news stories with 'read more' links attached; when users click on the link they are then directed to a malicious site where keylogging software- designed to capture financial information- exploits the Microsoft vulnerability.

Increasingly pervasive cyber criminals are constantly formulating more inventive viruses and experts have recognised that global brands, like the BBC, are ideal for hackers to hijack for the proliferation of malware.

Earlier in the week it was revealed that Mikhail Bulgakov's novel, The Master and Margarita, had been appropriated by spammers to provide links to websites selling performance enhancing drugs.

Graham Cluley the senior technology consultant at Sophos, a threat management solution company, warned: 'Anyone unfortunate enough to run malicious software could potentially be allowing hackers to gain access to their computer to spy, steal and cause havoc. Users need to savvy-up to reduce the risk of being taken in by greedy, money-grabbing internet criminals.'

Microsoft's next security update, due on April 11th, is reported to contain a patch for the vulnerability

Have you the time?

A fun project to do when you need a clock to run backwards.

This is a travel clock that you can set an alarm. In my experience with 3 or 4 different clocks with similar mechanisms the plate can be reversed to make the clock run counter-clockwise.

I use the scissors to place the clock shaft in the middle so it doesn't press on the gears while I work. The first thing is to get the back off of the clock to expose the gears. A small standard screwdriver is a good choice. Don't forget to take the small black knobs off the time adjustment wheel. If you don't they will shoot off as you pry the back cover of the clock.

Study the way this looks and remove parts slowly as you learn. The left most gear is minutes, the middle is seconds and the right and smallest gear below work together to calculate the second hand movement. The smallest gear turn approximately 180 degrees each second. Unfortunately, it is complicated to watch the clock with the cover removed as it requires an alignment hole to be in place on the cover side.

The gears simply pull straight up and out and you can set them down in order as you go. The focus is on the orientation of the plate inside the copper wound electromagnet. As you work the plate up and off of the pins that hold it in place, take care not to pull at the copper wound mechanism. The plate should slide out of a plastic rectangle slot, the copper is not wrapped around the plate itself.

This is the original orientation of the plate.

Some plates can be pulled out, flipped 180 degrees and be replaced, done. When it doesn't work like that, I nip off about 3/32 at a 45 degree angle as shown.

As you can see the plate is restored and it fits over the guide pins.

Take care when replacing the cover that the smallest gear is pointing straight up as much as possible to align it for the cover. When the cover is replaced it won't smash the shaft. If the shaft gets smashed they might weaken too much to be straightened again. During this mod one of the wires came off underneath the copper winding and the clock wouldn't work, so I soldered and reassembled.

Car amp

A friend of mine gave me an old stereo...after ripping the cd player apart to get his cds out... that he claimed ate some of his cds... Since the stereo in my car died and with no money at the moment I decided to make this temporary car amp...

This is what the stereo looks like out side of the case with the cd player removed:

SInce the cd player no longer works there is no need to leave the motors still attached. I tried unhooking this daughter board completely, but the stereo will not stay on without it attached.

This is what the board will look like after the motors have been detached: I used a dremel witha cutting wheel to cut the board.

The problem of power arises, so I break out the voltage meeter and discover that the internal transformer was producing 12 volts, the same as a car. I decide to dissconnect the transformer and splice in a cigarette lighter power cord because the output in a car is also 12 volts. I could have eliminated this board all together, but I figured that it was a good idea to leave the fuses for protection.

I wasn't completely sure wich was negative and wich was posotive so I looked it up and then made the proper connections.

I discovered the input for audio from the cd player, I tried using the tape player input, but it was very distorted. With a little force the audio cord from the back of an old cd drive will fit the socket. I cut off the other end of the cord and sodder on two rca female connectors (right and left). A minni jack would have been more practicle, but I already had this cord made so I didn't moddify it. The two far left pins on this connector should be soddered together.

To make sure everything worked I drove around with it contained in this yellow case.

Closed:

I tapped the controlls on the outside temporaily for easy access...

After testing the prototype I realized that it was a pain in the ass tohave to reach in the back of the car to turn the volume up on power off. I thought of all of the buttons that I thought I might need to use while driving... I decided I would need the Power button, power led, the two volume buttions, bass boost led, and the bass boost button. After mapping out all the components and the paths of the 4 buttons I then came up with this diagram:

I made the board using a cheap pcb I bought at radio shack. Then I rolled out 8, 8 foot sections of insulated wire and twisted it together. Next I soldered the ends to the appropriate connections and here is the semi-finished product:

Close up:

Afther all that was finished I trimmed off the extra board and attacherd it to a floppy hole cover.

While dumpster diving at my school I found an old mac and scavenged the case from it, after a few modifications to the case everything fit inside perfectly...

I dremeled a hole for the speaker connections and attached the rca inputs

I made a bracket to hold the wires inplace and keep them from pulling out.

I put the top of the case on and vala... after marking the apple logo out with a sharpy it is ready to go.

back:

I installed it in the back window of my car on the passengers side so it didn't interfere with my view... It fit perfectly... I ran the green cords from the back on the passenger side, tucking them under panels when possible.

Back:

I use this along with an old 48x cd-rom drive to listen to music.

To power the cd rive I used this:

8000km/h flight a success

THE dream of two-hour passenger flights between Australia and the UK is a step closer to reality.

Scientists in the state's Far North yesterday dubbed the lift-off and 8000km/h flight of Hyshot IV as a success.

The scramjet engine flew for 10 minutes to an altitude of 300km before crashing into the ground - 400km from the take-off point at the Woomera rocket range.

Data from the flight will be analysed by the University of Queensland researchers over the next two months.

University associate professor Michael Smart said the data would enable researchers to see if scramjet technology could be used for supersonic commercial flights.

Dr Smart said the engine would cut flying times between London and Sydney to between two and three hours.

"In 10 years, we might start to see scramjet-engine flights transporting goods, such as medical supplies," he said.

"I think once people see that, the possibility of using the scramjet for commercial flights will become very real.

"It wouldn't be cheap to start such a service, and it would need someone like Richard Branson to help fund it."

The payload from the flight is expected to be found today.

A team of 10 scientists from the university has been in Woomera for the past three weeks organising two scramjet flights - the first of which was last Saturday.

The flights cost $1.5-$2 million each and were funded by the university, the Japanese Aerospace Exploration Agency and UK company QinetiQ.

Another four scramjet tests have been planned for Woomera over the next two years. The first were in 2001 and 2002

Apple Introduces iPod Update Enhancing Control Volume

Apple Computer is introducing a software update for its current generation of iPod music players in response to complaints about possible hearing loss caused by high volume levels, reports newsfactor.com.

The free software is available on the company's site. The upgrade offers new volume controls that help users set maximum levels. The software comes with parental locks as well that let parents set limits on their children's iPods.

“As the leading provider of digital music players, Apple continuously brings iPod customers innovative and easy-to-use solutions,” The Associated Press quotes Greg Joswiak, Apple's vice president for iPod marketing, as saying. “With the increased attention in this area, we want to offer customers an easy-to-use option to set their own personal volume limit."

The controversy started in February when an iPod owner filed suit against the company claiming that Apple provided insufficient warnings about volume levels and was producing a faulty product, reports newsfactor.com. Seattle law firm Hagens Berman Sobol Shapiro filed a lawsuit as well.

The law firm hails the new volume controls. However, the firm is of the view that Apple's update does not safeguard those who purchased earlier iPod models. They also have expressed displeasure with what they describe as Apple’s reluctance to educate users about the issue.

Apple releases each iPod with a warning that cautions, “permanent hearing loss may occur if earphones or headphones are used at high volume.”

Intel Shows its Rugged Side

Intel Corporation has launched a new rugged PC platform designed to meet the needs of rural villages and communities in India. The Community PC platform is based on Intel technology, and can operate in a community setting while accommodating varying environmental conditions throughout India.

The new platform is part of Intel’s Jagruti (Awakening) initiative, which is designed to bridge the urban-rural divide and provide rural Indian communities with economic and social opportunities. The program supports the spread of rural Internet kiosks based on the Community PC platform, and will be made possible through collaboration with leaders in business, government, education and online services.

The kiosks will accelerate access to information and communications technologies in villages throughout India. The new platform was designed to withstand the varying weather conditions of heat, dust and humidity in India, as well as unreliable power sources that can compromise typical PCs in those environments.

The Community PC platform supports remote diagnostics and control features under low power requirements. Features include a rugged chassis with a removable dust filter and integrated air fan to regulate the temperature of the motherboard. It also features a Customized Power Supply Unit comprised of an integrated power supply and UPS unit, enabling the PC to maintain continuous power in a power outage. Total power consumption of all peripherals is less than 100 watts, and the platform also features certified-based access, enabling banks to verify the validity of installment payments against the purchase of the PCs.

Internet kiosks are already common in Indian villages, and Intel expects many of the Community PC platforms to be deployed in these locations. The new platform creates entrepreneurship opportunities for prospective kiosk owner/operators, and Intel has already initiated several Community PC pilot projects throughout India.

“Intel actively supports efforts to provide computer technology to places where it hasn't previously been available,” said William M. Siu, vice president and general manager of Intel’s Channel Platforms Group. “Our experience shows that ICT adoption in developing nations requires much more than providing a standard PC; the technology often needs to be adapted to the local usage and environment of a particular country or region. In addition to defining the platform and developing the ingredient technologies, Intel also collaborated with local hardware, software and service companies to deliver on the promise of the Community PC platform. Overall, Intel has made substantial investments in technology, ecosystem partnerships, and education initiatives in support of this belief.”
