Apple and Samsung have pushed Nokia into the number three position for worldwide smartphone sales, analysts have claimed, with strong Q2 2011 performance leaving Symbian devices significantly overshadowed. Apple is now the number one smartphone manufacturer, Strategy Analytics‘ figures suggest, with 18.5-percent of the market, while Samsung comes in at second place, with 17.5-percent. In contrast, Nokia has 15.2-percent in the last quarter, less than half the 38.1-percent in the same period twelve months ago.

Apple shipping 20.3m iPhone units in Q2, and Samsung shipping 19.2m smartphone units. Strategy Analytics had previously suggested that Samsung could beat Apple to the top spot, but it seems the Korean company’s performance wasn’t quite sufficient to do so. Still, year on year Samsung has shown the bigger increase: from 5-percent in Q2 2010, versus Apple’s 13.5-percent in the same period.

Hong Kong physicists say they have proved that a single photon obeys Einstein's theory that nothing can travel faster than the speed of light -- demonstrating that outside science fiction, time travel is impossible.


The Hong Kong University of Science and Technology research team led by Du Shengwang said they had proved that a single photon, or unit of light, "obeys the traffic law of the universe."


"Einstein claimed that the speed of light was the traffic law of the universe or in simple language, nothing can travel faster than light," the university said on its website.


"Professor Du's study demonstrates that a single photon, the fundamental quanta of light, also obeys the traffic law of the universe just like classical EM (electromagnetic) waves."

The possibility of time travel was raised 10 years ago when scientists discovered superluminal -- or faster-than-light -- propagation of optical pulses in some specific medium, the team said.


It was later found to be a visual effect, but researchers thought it might still be possible for a single photon to exceed light speed.


Du, however, believed Einstein was right and determined to end the debate by measuring the ultimate speed of a single photon, which had not been done before.


"The study, which showed that single photons also obey the speed limit c, confirms Einstein's causality; that is, an effect cannot occur before its cause," the university said.


"By showing that single photons cannot travel faster than the speed of light, our results bring a closure to the debate on the true speed of information carried by a single photon," said Du, assistant professor of physics.

"Our findings will also likely have potential applications by giving scientists a better picture on the transmission of quantum information."

The team's study was published in the U.S. peer-reviewed scientific journal Physical Review Letters.

Last week, Google announced that their new hyper indexing system was live across all data centers.
Google just got fresher and faster with the release of their new indexing system, Caffeine. In short, old Google indexing = built with layers that would get refreshed at varying frequencies and result in content often not updated for days or weeks. New Google indexing (Caffeine) = analyzes smaller chunks of the web and updates continuously; so content is much fresher! So our Google now able to provide more and more updated results from the past 24 hours.



According to Carrie Grimes, Software Engineer at Google
"Caffeine provides 50 percent fresher results for web searches than our last index, and it's the largest collection of web content we've offered. Whether it's a news story, a blog or a forum post, you can now find links to relevant content much sooner after it is published than was possible ever before.

Some background for those of you who don't build search engines for a living like us: when you search Google, you're not searching the live web. Instead you're searching Google's index of the web which, like the list in the back of a book, helps you pinpoint exactly the information you need. (Here's a good explanation of how it all works.)

So why did we build a new search indexing system? Content on the web is blossoming. It's growing not just in size and numbers but with the advent of video, images, news and real-time updates, the average webpage is richer and more complex. In addition, people's expectations for search are higher than they used to be. Searchers want to find the latest relevant content and publishers expect to be found the instant they publish.

To keep up with the evolution of the web and to meet rising user expectations, we've built Caffeine. The image below illustrates how our old indexing system worked compared to Caffeine:


Our old index had several layers, some of which were refreshed at a faster rate than others; the main layer would update every couple of weeks. To refresh a layer of the old index, we would analyze the entire web, which meant there was a significant delay between when we found a page and made it available to you.

With Caffeine, we analyze the web in small portions and update our search index on a continuous basis, globally. As we find new pages, or new information on existing pages, we can add these straight to the index. That means you can find fresher information than ever before—no matter when or where it was published.

Caffeine lets us index web pages on an enormous scale. In fact, every second Caffeine processes hundreds of thousands of pages in parallel. If this were a pile of paper it would grow three miles taller every second. Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day. You would need 625,000 of the largest iPods to store that much information; if these were stacked end-to-end they would go for more than 40 miles.

We've built Caffeine with the future in mind. Not only is it fresher, it's a robust foundation that makes it possible for us to build an even faster and comprehensive search engine that scales with the growth of information online, and delivers even more relevant search results to you. So stay tuned, and look for more improvements in the months to come."

Phone 4. In so many ways, it's a first.

While everyone else was busy trying to keep up with iPhone, we were busy creating amazing new features that make iPhone more powerful, easier to use, and more indispensable than ever. The result is iPhone 4. The biggest thing to happen to iPhone since iPhone.

FaceTime

People have been dreaming about video calling for decades. iPhone 4 makes it a reality. With just a tap, you can wave hello to your kids, share a smile from across the globe, or watch your best friend laugh at your stories — iPhone 4 to iPhone 4 over Wi-Fi. And it works right out of the box. No other phone makes staying in touch this much fun.

Retina Display

The Retina display on iPhone 4 is the sharpest, most vibrant, highest-resolution phone screen ever, with four times the pixel count of previous iPhone models. In fact, the pixel density is so high that the human eye is unable to distinguish individual pixels. Which makes text amazingly crisp and images stunningly sharp.

Multitasking

iPhone 4 introduces a whole new way of multitasking. Now you can run your favorite third-party apps — and switch between them instantly — without slowing down the performance of the foreground app or draining the battery unnecessarily.1 This smarter approach to multitasking is available only on iPhone.

HD Video Recording and Editing

Shoot your own movies in high definition. Capture impressive video even in low-light settings, thanks to the advanced backside illumination sensor and built-in LED light. Then edit and create your own mini-masterpiece right on iPhone 4 using the new iMovie app — with Apple-designed themes, titles, and transitions. It’s coming soon to the App Store for $4.99.

5-Megapixel Camera with LED Flash

Take beautiful, detailed photos with the new 5-megapixel camera with built-in LED flash. The advanced backside illumination sensor captures great pictures even in low light. And the new front-facing camera makes it easy to take self-portraits.

And much, much more.

Pre-order iPhone 4 starting June 15.

Palm isn't hot on Pre overclocking, indicates warranties at risk[Repost of BloombergApril 12] Palm Inc., creator of the Pre smartphone, is seeking bids for the company as early as this week, according to three people familiar with the situation.

The company is working with Goldman Sachs Group Inc. and Frank Quattrone’s Qatalyst Partners to find a buyer, said the people, who declined to be identified because a sale hasn’t been announced. Taiwan’s HTC Corp. and China’s Lenovo Group Ltd. have looked at the company and may make offers, said the people.

Palm, which helped pioneer the market for personal digital assistants, would offer suitors the WebOS software that competes against mobile operating systems from iPhone maker Apple Inc. and Google Inc. For Elevation Partners LP, the firm that owns about 30 percent of Palm, a sale may end the volatility of an investment in a stock that surged more than 10-fold since December 2008 before erasing most of the gain.

“Palm still has quite a good brand in the U.S. market, and some strong technology, so you can do something with it,” said Frank He, a technology analyst at BOC International Holdings Ltd. in Hong Kong. “The shares have gone down a lot and the company may become attractive to anyone looking for a turnaround play.”

The Sunnyvale, California-based device maker surged 32 percent last week on the Nasdaq Stock Market on renewed speculation of a takeover bid. Before the rally, the stock had plunged more than 60 percent this year, dragged down by disappointing sales of the Pre and Pixi phones.

Missing Estimates

Palm rose 71 cents, or 14 percent, to $5.87 at 9:38 a.m. New York time in Nasdaq Stock Market trading. Earlier the stock jumped as much as 16 percent.

Chief Financial Officer Doug Jeffries last month forecast sales in the quarter ending in May will be less than $150 million, compared with the $300 million average of analysts’ estimates compiled by Bloomberg at the time.

Palm, which had a market value of $870.8 million before today, ranked sixth in the North American smartphone market during the three months ended Dec. 31 with a 4.3 percent share, according to Gartner Inc. Research in Motion Ltd., maker of the BlackBerry, led with 44 percent, followed by Apple’s 24 percent, according to the Stamford, Connecticut-based research company.

Chief Executive Officer Jon Rubinstein, who developed Palm’s latest operating system, was counting on the Pre and Pixi smartphones to attract customers. The company has patents from mobile hardware to software and power-saving technologies.

Lenovo, Dell

Lynn Fox, a Palm spokeswoman, declined to comment. Qatalyst’s Sally Palmer and Goldman’s Andrea Rachman didn’t immediately respond to requests for comment. Chen Hui-Ming, the chief financial officer of HTC, declined to confirm or deny the company’s interest in Palm.

Wong Wai Ming, Lenovo’s chief financial officer, also declined to comment on the company’s acquisition plans. In January, Lenovo paid $200 million to purchase Lenovo Mobile Communication Technology Ltd., letting it re-enter the market for handsets. The company had sold the mobile-phone unit in 2008 to focus on personal computers.

Palm shares have been buoyed in the past on speculation the company would be bought by Nokia Oyj. The Finnish company today declined to say if it might be interested.

“We never speculate or comment on market rumors,” said Arja Suominen, a Nokia spokeswoman.

Dell Inc. looked at Palm, though it decided against an offer, according to two of the people familiar with the matter. Jess Blackburn, a spokesman for the Round Rock, Texas-based computer maker, didn’t respond to a call for comment.

Burning Cash

Unlisted Huawei Technologies Co. and ZTE Corp., China’s two biggest makers of phone equipment, may be more likely bidders for Palm than HTC or Lenovo, said Lu Chia-lin, a technology analyst at Macquarie Group Ltd. in Taipei.

Chinese companies “have been quite eager to expand their international markets,” said Lu.

Palm may burn $80 million every three months for the next five quarters as competition in the smartphone market intensifies, Berenberg Bank analysts including Adnaan Ahmad wrote in a March 25 report. The company held $592 million in cash and short-term investments at the end of its fiscal third- quarter, according to the report.

Ross Gan, a spokesman at Huawei, said the company is always open to opportunities, though he declined to comment on speculation about mergers and acquisitions as a matter of policy. Margrete Ma, a ZTE spokeswoman, couldn’t immediately be reached for comment.

Market Pioneer

After Palm introduced the Pre at the Consumer Electronics Show in January 2009, the stock jumped 80 percent in two days to $5.96. By September, the shares had climbed as high as $17.46.

The stock then dropped 79 percent over the next six months as Palm’s sales growth was outpaced by marketing costs, and the company lost market share to Apple and phones equipped with Google’s Android. Palm has posted 11 straight quarterly losses.

Founded in 1992, Palm helped pioneer the market for handheld organizers with its PalmPilot devices. The company was acquired by U.S. Robotics, which was in turn purchased by 3Com Corp. 3Com spun off Palm in 2000.

Rubinstein joined the company after leading development of Apple’s best-selling iPod media player. He was recruited to Palm by Fred Anderson, Apple’s former finance chief and a co-founder of Elevation Partners.

The Pre was Palm’s first phone based on WebOS. It went on sale in June 2009, followed by the smaller, cheaper Pixi in November. The phones let users send e-mail, surf the Web, stream video and run multiple applications at the same time.

Both devices were sold in the U.S. exclusively by Sprint Nextel Corp., the country’s third-largest carrier, until Verizon Wireless began offering enhanced versions in January.
