If you want buy digital camera. Few features you must consider:

 How many mega pixel camera do you need?

2 megapixels or less

* This is typically found on smaller, inexpensive cameras or cameras in combination with other devices (such as cellphones or PDAs).
* It will be hard to make a high-quality print of any size, but these are just fine for e-mailing photos or posting photos for a personal web site.
* I wouldn’t recommend it for family portraits or if you really need a nice-looking print.

3 megapixels

* This is actually a good compromise between picture quality and low price for most casual photographers.
* You can print lovely 4×6 images, decent 5×7s and, depending on the camera, might even knock out a good 6×9 or 8×10.

4 megapixels

* You’re getting nicer. These images make practically photo-lab quality 4×6s, and great 5×7s and 6×9s.
* You can print a nice 8×10.

5 megapixels

* Hello, enlargements! This will produce beautiful 8×10s, and even a nice 11×14.
* Now you are getting closer to professional photographer levels, and the quality shows it.

6 megapixels and up

* Wonderful image quality, but high price tags. You can print large photos, even 11×14 or perhaps more, with satisfying results.
* There are some high-megapixel cameras coming out with lower price tags than most, but they usually have very few features.
* Unless megapixels are the only thing you care about (it shouldn’t be), don’t get a camera that sounds outrageously inexpensive for its megapixel range.

Contrary to popular assumption, DRAMs used in most modern computers retain their contents for seconds to minutes after power is lost, even at operating temperatures and even if removed from a motherboard. Although DRAMs become less reliable when they are not refreshed, they are not immediately erased, and their contents persist sufficiently for malicious (or forensic) acquisition of usable full-system memory images. We show that this phenomenon limits the ability of an operating system to protect cryptographic key material from an attacker with physical access. We use cold reboots to mount attacks on popular disk encryption systems — BitLocker, FileVault, dm-crypt, and TrueCrypt — using no special devices or materials. We experimentally characterize the extent and predictability of memory remanence and report that remanence times can be increased dramatically with simple techniques. We offer new algorithms for finding cryptographic keys in memory images and for correcting errors caused by bit decay. Though we discuss several strategies for partially mitigating these risks, we know of no simple remedy that would eliminate them.

Japan successfully launches high-speed Internet satellite

TOKYO (AFP) — Japan successfully launched Saturday an experimental satellite aimed at providing high-speed Internet access across Asia, even when terrestrial infrastructure goes down, the space agency said.

The domestically developed H-2A rocket carrying the Kizuna satellite was launched at 17:55 pm (0855 GMT) with no glitches from the Space Centre on Tanegashima island off the southern tip of Kyushu Island, southern Japan.

The communications satellite, expected to be in use for five years, separated from the rocket approximately 35 minutes after the launch, said an official of the Japan Aerospace Exploration Agency (JAXA) during a live broadcast.

The 342 million dollar-Kizuna will allow super-high speed data communications of up to 1.2 Gbps, which would make it the fastest in the world, the agency said.

That rate would translate to 150 times that of the average high-speed ADSL connection rate of 8 Mbps, or 12 times the speed of a fibre-optic communication delivery to a person’s premises (FTTP).

The “Kizuna,” which also means “bond” in Japanese, is expected to begin transmitting and receiving data with terrestrial infrastructures in July after completing preparations and confirming the satellite’s safety.

Japan is looking to use the satellite to allow communication when a ground-based network is severed by a disaster in any Asian country, in which case it would be used to transmit data to crisis management offices.

The agency is hoping it can also be used as an educational or medical tool to reach people in remote or mountainous areas.

“The Internet is now an integral part of our lives; but its infrastructure levels vary. Urban areas … have a better environment, whereas some mountainous regions and remote islands are not well-equipped,” JAXA said on its website.

The satellite will enable students in Asian countries to communicate smoothly and with no time lag among one another, as if they were in the same classroom, it said.

The satellite will to last five years, an agency spokeswoman said.

The launch was delayed by one week after JAXA said it had discovered a problem with the gas jet thruster for its launch rocket.

Japan, like developing Asian powers China and India, has been stepping up its space operations and has set a goal of sending an astronaut to the moon by 2020.

Japan faced an embarrassing failure in November 2003, when it had to destroy a rocket carrying a spy satellite 10 minutes after lift-off because a booster failed to separate.

However, Japan’s first lunar probe, Kaguya, was successfully launched last September, releasing two baby satellites which will be used to study the gravity fields of the moon among other projects.

The 55-billion-yen (500-million-dollar) lunar probe is the most extensive mission to investigate the moon since the US Apollo in the 1960s and 1970s.

OTTAWA, CANADA – February 14, 2008 – Overlay.TV, an interactive media company, today launched a revolutionary video-commerce platform that will enable an entire generation of online video publishers to express themselves in a new way by personalizing and monetizing the billions of videos currently posted to the Internet. The Overlay.TV platform offers a simple way for publishers to unobtrusively link images within a video to marketers’ web sites – instantly converting passive online video content into an interactive revenue model.

Starting today, the platform is now available on Overlay.TV at http://www.overlay.tv, where users can customize their video and embed the overlaid video anywhere, including blogs, personal websites and social networking profiles. Overlay.TV has also developed a specific application for Facebook users, allowing single sign-on so that current Facebook users can use their Facebook log-in information to seamlessly access the Overlay.TV site.

At time of launch, more than 600 marketing affiliates have agreed to accept user “click-throughs” from Overlay.TV, including Amazon.com, iTunes and Wal-Mart. The platform is compliant with all major browsers, including Internet Explorer and Firefox. The platform can also be used by content owners and marketers to enrich their online video assets and encourage greater online community building through interactivity.

“By linking publishers, viewers of online video and marketers, Overlay.TV is transforming user-generated video content from a passive vehicle for entertainment or education, into an interactive vehicle for commerce,” said Rob Lane, President and CEO of Overlay.TV. “We’re empowering a whole new generation of publishers – a group we call ‘Generation P’ – with a user-friendly platform that will help them discover entirely new business models. The advertising industry has significantly shifted from traditional channels to web advertising. With the ubiquity of social networks, consumer-created advertising has more power and influence than anything produced by industry professionals.”

How it Works

The Overlay.TV platform enables video to stream from most of the popular video sharing sites like YouTube, Metacafe, MySpace, Google Video and Yahoo! Video; among others. Publishers can overlay pictures, words, graphics on top of video and link to products or information on external websites. They can then share the enhanced video via email, their blogs, social networking profiles, personal websites and social bookmarking sites like del.icio.us and Digg. These capabilities allow the publishers to easily express themselves by putting their creative mark on the video. This also enhances the viewing experience for their friends and their network, without changing the integrity of the original video or interrupting the viewer’s experience. As video streams from its original location, viewers are able to opt-in to view “overlays” or turn them off.

Press Release

http://www.overlay.tv

Early today, Microsoft announced its bid to acquire Yahoo! for $44.6 billion. The offer amounts to $31 per share, a 62 percent increase over Yahoo’s stock price of $19.18 on Thursday. The proposed deal, as widely reported, signals Microsoft’s intensified aggression against Google, which dominates Internet search with 60 percent of the market, as well as online advertising. The bid, if accepted, would be Microsoft’s priciest acquisition to date.

Can Microsoft and Yahoo’s combined force, which would represent about 30 percent of the Internet search market, effectively rival Google? The answer remains to be seen, of course — besides whether or not Yahoo will accept Microsoft’s bid, there’s the legal question of whether the acquisition would violate antitrust regulations. Most reports, however, suggest the inevitability of this effort. The New York Times outlines Microsoft and Yahoo’s failed discussions of a merger in May, leading to Microsoft’s current “hostile” bid and the possibility of mounting a proxy contest for control of Yahoo’s board.

One immediate effect has already been seen in the stock exchange. Today’s afternoon trading showed an increase of nearly 50 percent in the value of Yahoo’s shares, at about $28.50. On the other hand, the value of Microsoft’s shares declined by 6 percent. Google’s shares showed a similar change, with a 7 percent decline in value.

This short-term effect mirrors long-term possibilities, as contemplated by Tim Weber of BBC News. While Yahoo, which has watched its stock fall and just today appointed a new chairman, Roy Bostock, stands to benefit immensely from Microsoft’s generous resources, this move could represent either Microsoft’s greatest coup or its final hurrah, according to Weber.

“Microsoft knows that its stronghold, the PC business, is getting less and less important,” he writes. “The future of today’s IT industry is the rapidly growing mobile internet space, and Google has made no secret that it is prepared to spend a lot of money to conquer this market.”

The BBC News analysis ends with a flashback to the oft-maligned AOL-Time Warner merger. At The Wall Street Journal’s DealJournal, Dennis Berman explores this angle in depth, echoing a common critique of Microsoft — that it favors acquisition over innovation. In order to succeed against Google, Microsoft and Yahoo will have to prove this assertion false.

Switching on a giant atom-smashing machine might open the door to unexpected visitors - from the future, it has been claimed.

The Large Hadron Collider (LHC), due to come on stream this year, could turn out to be the world’s first time machine, according to two Russian scientists.

Their calculations show it is possible the machine will tear a hole in the fabric of space and time, creating a gateway to tomorrow. And, with sufficiently advanced technology, people from the future might even be able to walk through it.

The vast LHC has been constructed at CERN, the European particle physics centre near Geneva.

Designed to investigate the origins of the universe, it will generate particles with so much energy that scientists are not entirely sure what will happen when they switch the machine on.

One possibility is that microscopic black holes will be created within the LHC.

But Russian mathematicians Irina Aref’eva and Igor Volovich point to another scenario. They believe a “wormhole” could open up, linking our time with another in the future.

Such a time tunnel would need to be propped open for anyone to step through it. But this could happen if “dark energy” - the mysterious anti-gravity force that causes galaxies to accelerate away from each other - possesses a special “phantom” property.

The year 2008 might then become “Year Zero” for future time travellers, since it would only be possible to travel back as far as the first doorway in time.

Manipulating such a wormhole to create a viable time machine would take incredibly advanced technology, New Scientist magazine reported - yet this could not be ruled out in the distant future.

There are two notable things about Cern, the European Organisation for Nuclear Research.

As the world’s leading particle physics laboratory, it is staffed by people with very large brains.

It is also where Tim Berners-Lee, a former scientist at Cern’s Geneva headquarters, invented the worldwide web as a way to share information among the global research community that contributes to the organisation’s work.

So when the people with very large brains tell you they are undertaking an experiment so complex that they need to build the next generation of the web to support it, the IT industry should sit up and take notice.

Cern is a funded jointly by 20 European countries, with 3000 staff supporting 6500 researchers in 35 nations.

The web was created in 1989/90 when Berners-Lee devised a way to share information between the computers used by Cern’s scientific community. The first browser was developed and the web as we know it was born.

But Cern has moved on since then and its next experiment, scheduled for 2007, will drive new developments in technology and manufacturing that will benefit all of industry.

The laboratory is building the Large Hadron Collider (LHC) - a 27km circumference tube 100m underground that will accelerate beams of particles to near-light speed, then crash them into each other to study what happens.

The aim of the project is to simulate the events taking place one millionth of a millionth of a second after the universe was created - information that could revolutionise our understanding of how the natural world works.

The LHC will be the world’s largest scientific instrument, says Derek Mathieson, deputy group leader of internet development services at Cern.

Building such a device will challenge the manufacturing industry to develop new processes to produce the precision components needed.

‘The steel collar for the accelerator is made from a special steel in Japan, and cut in Europe to one-fiftieth of a millimetre precision - and we need six million of them to build the LHC,’ said Mathieson.

The challenge for the technology industry will be just as great.

Scientists will have to analyse vast amounts of information - two petabytes of data will be generated every second. Not all of this is needed - but 10 petabytes will be retained every year during the 10-year project, which would require the power of 100,000 of today’s fastest PCs to process.

To share and manage this data Cern is building the LHC Computing Grid - and contributing to the development of grid technologies that will be commercialised by IT suppliers to build the future internet that every consumer and business will one day use.

Grids are distributed networks of computers that share resources such as storage and processing power, making use of spare capacity to create a single, virtual system. In the grid-oriented future of the web, all applications will run in the network, rather than on corporate servers that are connected to the internet. Grids could act as the basis for computing utilities, with processing power provided through a socket in the wall and charged for in the same way as electricity.

Leanne Guy, a section leader in Cern’s LCG team, says the work will have commercial benefits, because it is part of the European DataGrid project, a European Union initiative to create a grid for collaborative research. DataGrid software is already installed on hundreds of systems throughout the world.

To make sure the results can be widely used, developments are done using both commercial and open-source software - Cern uses Oracle’s 9i database and application server, as well as open-source equivalents MySQL and Tomcat.

‘We are required to provide an open-source alternative for all our developments in grid data management for research institutes that are smaller and can’t afford the investment in commercial software and skills,’ said Guy.

The first release of LCG is scheduled for June, and Guy hopes to have a ‘real production system’ in place by the end of next year.

It will be several years before the next generation web becomes an everyday business tool - but the work of the people with very large brains will inevitably bring another huge advance for the IT industry.

A gadget is a device or an appliance that has a useful specific practical purpose and function but is often thought of as a novelty. Gadgets are invariably considered to be more unusually or cleverly designed than normal technology at the time of their invention. Gadgets are sometimes also referred to as gizmos.

History

People where using gadgets since the beginning of history. These devices that have been created by people make their life better and full up their bellies. So what are those best gadgets that we still use today? Of, course he use modifications of those but the principles are the same. They have let humanity learn the basics of sciences and technology and lead us to this level of development.

At the very beginning people where gathering berries, plants roots, fruits and vegetables they were finding to feed themselves. Then they started hunting using sticks and rocks to kill animals. So the best gadget created at that time was a simple bow. Bow hunters were the most successful and they also used bows to protect themselves from other people. This would be the most popular gadget on digg if only they had digg back then. Well, the problem is that they did not have any social networks because they did not have Internet they where only planning on creating something like that, but I am sure they were discussing this news very much.

Later on, ages later, when humans needed to carry heavy stuff they have just designed wheel. Why so late? They just did not need it earlier. However, the result of their wheel creation we have cars and all the things that use round things. For example watches have gear wheels, our cars have wheels, most of mechanical devices have something that looks and functions like wheels. Hey, even iPod’s controlling wheel is round. See, what would we do if those people wouldn’t create the wheel we would have a square one?
