Israel says it arrests Tel Aviv bus bomber

JERUSALEM (AP) ? Israeli authorities arrested an Arab Israeli on Thursday on accusations he planted a bomb on a bus in Tel Aviv that wounded 27 people and threatened to sabotage efforts to broker a cease-fire to end the fighting in Gaza, police said.

Police spokesman Micky Rosenfeld said the man, from the village of Taybeh in Israel, was connected to the Hamas and Islamic Jihad militant groups.

A Palestinian militant cell based in the West Bank village of Beit Lakiya sent the man to put a bomb connected to a mobile phone on the Tel Aviv bus Wednesday, Rosenfeld said.

After he planted the bomb, the man, who police declined to identify, left the bus and called his handlers, who remotely detonated the explosive by calling the phone, he said.

"He admitted to carrying out the terrorist attack," Rosenfeld said.

Attacks by Israeli Arabs are rare, though they have happened in the past.

The attack brought back harsh memories of frequent bus bombings during last decade's violent Palestinian uprising.

Reasons to Outsource | City Business Community

Reasons to Outsource Reasons to Outsource Another way to extend your capacity is outsourcing. Outsourcing consists of arranging for some of your work to be performed by another person or business. It enables you to focus on your own core competencies while gaining access to expertise in other areas. The reasons why you may want to outsource some activities include cost savings, skills, flexibility, innovation and experience.

Cost savings

The main reason for outsourcing is to save money. Outsourcing may be cheaper than doing something yourself because the supplier has economies of scale, giving you cheaper access to their technology or expertise. Without having to make a large front-end investment, you can also undertake new projects without a big financial risk.

Skills

One of the limitations of going solo is that you may not have all of the skills necessary for a particular job. Outsourcing is a way to gain access to people with the right skills without having to hire staff.

Flexibility

Outsourcing can make your operation more flexible by giving you quick access to short-term resources. For example, outsourcing enables you to bid for several jobs at once without worrying about how you will handle all the work if you get it.

Innovation

Innovation is often the hallmark of a successful solo business. However, sometimes the ideas stay submerged in your subconscious. One way to get a fresh viewpoint is to outsource part of the job to someone who can innovate for you.

Experience

Outsourcing is a way to bring the benefits of another person?s experience into your operation. If you do not have enough experience to confidently take on a job, then outsourcing will not only get the job done, but you will also gain additional experience in the process.

Greenhouse gases hit record high

The concentration of greenhouse gases in the atmosphere hit a record high in 2011, the United Nations' World Meteorological Organization (WMO) reported Tuesday (Nov. 20).

Chief among these heat-trapping gases is carbon dioxide (CO2), the biggest culprit behind global warming. Carbon dioxide levels reached about 390.9 parts per million last year, which is 140 percent of the pre-industrial level of 280 parts per million and nearly 2 parts per million higher than the 2010 carbon dioxide level, according to the WMO report.

The international body estimates that about 413 billion tons (375 billion metric tons) of carbon have been released into the atmosphere since 1750, primarily from fossil fuel combustion. About half of this atmospheric carbon dioxide remains in the atmosphere, and much of it will linger for centuries, causing the planet to warm further, WMO Secretary-General Michel Jarraud warned.

Historically, the Earth's oceans and forests have helped balance the atmosphere's carbon equation by sucking up large amounts of the greenhouse gas. But Jarraud said natural carbon sinks might not be able to mitigate the problem as effectively in the future.

"Until now, carbon sinks have absorbed nearly half of the carbon dioxide humans emitted in the atmosphere, but this will not necessarily continue in the future," Jarraud said in a statement. "We have already seen that the oceans are becoming more acidic as a result of the carbon dioxide uptake, with potential repercussions for the underwater food chain and coral reefs. There are many additional interactions between greenhouse gases, Earth's biosphere and oceans, and we need to boost our monitoring capability and scientific knowledge in order to better understand these."

Greenhouse cases trap heat within the Earth's atmosphere and create a warming effect on the climate known as radiative forcing. From 1990 to 2011, radiative forcing by greenhouse gases shot up 30 percent, with carbon dioxide blamed for about 80 percent of this increase, according to the National Oceanic and Atmospheric Administration (NOAA).

Besides carbon dioxide, methane (CH4) and nitrous oxide (N2O) are also implicated in the greenhouse effect. In 2011, the level of methane in the atmosphere reached a new high of about 1,813 parts per billion, or 259 percent of the pre-industrial level, due to increased emissions from human activities, such as cattle breeding, rice farming and fossil fuel use. The atmospheric concentration of nitrous oxide, meanwhile, hit about 324.2 parts per billion last year, or 120 percent of the pre-industrial level and 1 part per billion above the 2010 level.

Black Friday Sales Kick Off Holiday Shopping Season


* Wal-Mart "Black Friday" deals at 8 p.m., Target open at 9
* NRF sees holiday sales up 4.1 pct, down from 2011 increase
* Waiting in tents at Best Buy in Florida, but some just look
By Martinne Geller and Phil Wahba
NEW YORK, Nov 22 (Reuters) - U.S. shoppers took advantage of retailers offering a Thursday night start to the traditional post-Thanksgiving holiday shopping season, lining up at stores to get deals on electronics and other items or to just see what the fuss was about.
This year, Target Corp joined Wal-Mart Stores Inc and Gap Inc in being open at least part of the day on Thursday and some retailers will be open throughout the day, a trend that began to take hold in 2011.
Wal-Mart's U.S. discount stores, which have been open on Thanksgiving Day since 1988, offered some "Black Friday" deals at 8 p.m. local time and special deals on some electronics at 10 p.m. Target has moved its opening from midnight to 9 p.m. on Thursday and Toys R Us is opening at 8 p.m.
"It's a recognition that retailers need to be more aggressive and want to show their physical stores are important," Moody's senior analyst Charles O'Shea said.
While he didn't see enormous crowds out in Vauxhall, New Jersey, he did see about 15 people lined up already at a Best Buy, which opens at midnight. At a Target in Westbury, only two shoppers were in line for a 9 p.m. opening. Still, for retailers, any crowd could make the effort worth it.
"It's a finite pie; if you can get a bit more by being open, then do it," O'Shea said.
The National Retail Federation, an industry trade group, forecast a 4.1 percent increase in retail sales during the November-December holiday period this year, down from the 5.6 percent increase seen in 2011.
Some retailers, like Best Buy Co Inc are keeping Black Friday on Friday, waiting until midnight to open.
At a Best Buy in Orlando, people had camped out in tents for days waiting for the doors to open.
Gabriel Esteves, 33, a self-employed car audio installer, waited in line with a bag of Cheetos and a Coke while his brother and sister went to their homes for Thanksgiving feasts with their families.
"They told me to take a break and go to the house, but today's the worst day to leave the line. People come and cut in line," said Esteves, who got in line Monday to buy some small electronics and a 50-inch television.
Best Buy, which is trying to stem falling sales under new CEO Hubert Joly, is one of the retailers in the spotlight this season.
At some stores, workers were not so happy to have early openings encroach on their Thanksgiving holiday. A petition asking Target to "save Thanksgiving" had 371,606 supporters as of Thursday afternoon.
Still, at a Target on Chicago's northwest Side, the first person waiting in line Thursday night was someone who worked at the store, Elsa Acevedo, 46, who finished her shift at 4:30 a.m. and lined up at about 2:30 p.m. to buy a 50-inch Westinghouse television.
As for the earlier opening, "I just think it takes people away from their families," she said. But she added that a midnight opening also pulled workers away from Thanksgiving celebrations because they had to prepare the stores to open.
Many shoppers lured into stores by earlier openings on Thursday may just be window-shopping.
More than 50 percent of consumers will do some form of "show-rooming" during the Black Friday weekend, said Kevin Sterneckert, vice president of retail research at Gartner Group.
"They will buy things because they looked at it in the store. They will touch and feel what they are interested in and then buy it online on Monday, either from the same retailer or a different online retailer," Sterneckert said.
At a Kmart on 34th Street in Manhattan earlier Thursday, Charles Montague, a 55-year-old mover, was browsing the aisles just to kill time.
"I don't holiday shop," he said emphatically. "I buy stuff all year long, not during some man-made holiday."
Some were not waiting for Monday to buy on the Internet. Online Thanksgiving 2012 sales were already up 17.8 percent over Thanksgiving 2011 for the same period, measured through 9 p.m. EST, according to IBM.

THE RESULTS MATTER
The stakes are high for U.S. retailers, which can earn more than a third of their annual sales in the holiday season.
Consumers heading into the holiday shopping season remain worried about high unemployment and possible tax increases and government spending cuts in 2013. Also, lasting effects of Sandy, the storm that lashed the densely populated East Coast in late October, could cut into how much shoppers can spend on the holidays.
According to a Reuters/Ipsos poll, two-thirds of shoppers said they were planning to spend the same amount as last year or were unsure about spending plans, while 21 percent intend to spend less and 11 percent plan to spend more.
"My family decided not to buy (Chanukah) presents this year - only for the kids. It's too expensive," said graduate student Danielle Slade, 29, from Jericho, Long Island.
Still, the Standard & Poor's retail index is up almost 27 percent this year, compared with a 10.6 percent increase for the broader S&P 500.
In New York's Times Square, a mix of locals and tourists lined up at Toys R Us.
"We just want to see what's happening," said a man who arrived Thursday from Paris. "We want to see what Black Friday is." A Santa hat-wearing expeditor quickly whisked him and his companion away before they could give their names.

Courting Asia, Obama finds that the world intrudes

WASHINGTON (AP) ? For all the attention wrenched elsewhere in recent days ? on new violence in the Middle East, the "fiscal cliff" back home ? President Barack Obama's speedy trip to Southeast Asia achieved a major goal: It was clearly seen in the region as a validation of Asia's strategic importance as the U.S. refocuses its foreign policy to counter China's clout.

It wasn't easy. Even in a Buddhist monastery in Thailand, Obama could not escape the budget woes waiting for him back home. And his historic visit to Myanmar was all but drowned out by the rocket fire and missile strikes between Israel and Gaza. He went half a world away to promote U.S.-style democracy but couldn't leave his troubles behind.

Even as Obama traipsed in stocking feet through a temple in the heart of Bangkok, a monk wished him luck negotiating the deficit-reduction challenge awaiting him in Washington. And the bloodshed in the Middle East, exploding as he toured Southeast Asia for three days, illustrated the limits of U.S. foreign policy even as he tried to display its influence and reach.

But he came away from his trip to this corner of the world ? a place once defined by a cloistered and shunned nation like Myanmar or by Khmer Rouge "killing fields" or by Chinese power ?with at least the hope that the example of U.S. democracy can effect change and strengthen America's hand.

He made his case clearly during a Bangkok news conference:

"It's worked for us for over 200 years now, and I think it's going to work for Thailand and it's going to work for this entire region," he said. "And the alternative, I think, is a false hope that, over time, I think erodes and collapses under the weight of people whose aspirations are not being met."

Establishing a bigger, more influential presence in the Asia-Pacific region has long been an Obama objective, a goal driven by 21st century geopolitical considerations and by the Hawaiian-born president's own self-identity as the first Pacific president.

Just by making the trip ? and by making it his first after his re-election ? Obama made a point about the importance the U.S. attaches to the region.

He was greeted by large crowds chanting his name in Thailand and in Myanmar, a country less than two years removed from a repressive military dictatorship where such assemblies were long forbidden. The English-language Myanmar Times newspaper heralded the arrival of "O-Burma" on its front page, while Thai newspapers praised his apparent interest in the native brand of Buddhism following his monastery visit.

The reception was more muted in neighboring Cambodia, a staunch ally of China that pointedly displayed a sign at the presidential palace welcoming Chinese premier Wen Jiabao but nothing for Obama. Still, there was a message for Asia in Obama's mere presence. The president was attending an annual summit of Southeast Asian leaders in Phnom Penh, yet another indication of U.S. intentions to pay a bigger role in the region.

The trip marked the first time a U.S. president had visited Myanmar and Cambodia.

For decades, Myanmar, despite its alluring pagodas and verdant countryside, was an international outcast with a repressive military junta accused of gross human rights abuses. But last year it began to shift toward democracy, and Obama went there to welcome the change and encourage more.

His motorcade sped to the lakeside home of opposition leader Aung San Suu Kyi, the Nobel Peace Prize winner who spent the better part of 20 years under house arrest. He embraced her and praised her as an "icon of democracy."

Obama's aides hoped that image would dominate back in the United States, but news events and coverage didn't go quite as planned. Hostilities in Israel and Gaza overshadowed the president's trip. He spent every day monitoring developments. Monday night he was on the phone until 2:30 from Phnom Penh, calling Israeli Prime Minister Benjamin Netanyahu once and Egyptian President Mohammed Morsi twice.

By Tuesday morning he had dispatched Secretary of State Hillary Rodham Clinton, who had been traveling with him in Southeast Asia, to the Mideast to engage directly in Jerusalem and Cairo. And he called Morsi again from Air Force One on the way home.

Efforts to break a stalemate with Congress over a deficit-reduction package also dogged him, even as congressional and White House staffs worked to frame details that Obama and legislative leaders could begin negotiating next week.

After the monk surprised him by wishing him well on the fiscal cliff at the Wat Pho monastery, Obama still could not escape it, facing a question about it during his Thailand press conference. No problem, the Americans said.

"We believe the United States can walk and chew gum at the same time," Deputy National Security Adviser Ben Rhodes said Tuesday in Phnom Penh. The shift of resources and attention to Asia will occur with or without diversions, he said. "We'll continue to move forward with our pivot even as we manage the inevitable crises and challenges that will come up in other regions."

Indeed, after spending months mired in a biting presidential campaign, Obama appeared to revel in being back on the world stage.

The trip was poignant, too. It marked his last overseas tour alongside Clinton, his former rival turned partner. Clinton has long said she plans to leave the administration ahead of Obama's second term, or shortly after it is under way.

Obama and Clinton flew across Southeast Asia together on Air Force One and walked down the plane's front steps together in Myanmar and Cambodia.

He singled her out at Suu Kyi's home. "I could not be more grateful, not only for your service, Hillary, but also for the powerful message that you and Aung San Suu Kyi send about the importance of women ? and men ? everywhere embracing and promoting democratic values and human rights," Obama said.

Aides said the two reminisced aboard the presidential plane flying back from Myanmar to Cambodia.

Clinton herself said traveling with Obama one last time was "bittersweet, nostalgic, all the things you would expect."

Quantum Cryptography At The End Of Your Road

In April of this year I wrote about how quantum cryptography (more properly called Quantum Key Distribution or QKD) was leaving the laboratory bench and is balanced on the cusp of entering into real-world use. At the time, many thought I was talking about the far distant future.? However, as is so often the case, people underestimate how rapidly technology moves on. A paper just published by a research group in Cambridge UK could be a game changer for QKD.

One of the main objections to QKD has been the expense. It has been necessary to have fibre optic cabling dedicated to the task (so called dark fibre). With dark fibre, in the absence of other data signals, secure key rates exceeding 1 Mb/s and a transmission distance of over 250 km have been achieved. Until now, the idea of leasing such fibres from telecoms providers has put potential users off at the first hurdle.

However, the results of the Cambridge team provide a technique where QKD can be used on a fibre optic cable that is already being used for other communications traffic. The ability to use shared fibres has suddenly, and to many people?s surprise, made QKD an economic prospect, with costs likely to be little different to a corporation fitting a top-end firewall.

QKD and traditional data traffic are at opposite ends of the brightness scale. When beaming traditional data down a fibre, you try to use high power levels in order that it will travel as far as possible without the need to ?repeat? the signal.? QKD, however, requires light intensities at the lowest imaginable levels.? With QKD, we are trying to send and detect single photons of light. Not only that, but we need to be sure that our transmission method isn?t interfering with the ?quantum state? of the photon, which is the very property upon which QKD relies.

I describe the task of using shared fibres for QKD as like trying to see the stars whilst staring at the sun. One simply overwhelms the other.

What the Cambridge team have succeeded in doing is switching between the various light sources so rapidly, and so cleanly, that very small numbers of photons can be sent and detected in between the pulses carrying the traditional data.? The timing needs to be extraordinarily accurate as the system opens a ?gate? to let through single photons for only a tenth of a billionth of a second.

The trick is that the pulse that contains the QKD photons has to be coordinated with the detectors, so that they know when to expect the one QKD photon between the pulses of millions of standard data photons.? By using such accurate ?time slicing?, it is now possible to at one instant stare at the sun and then momentarily see the stars.

The technique announced is so accurate that the speed at which QKD can be transmitted is not materially different to what was achieved using dark fibre, whilst the rates for standard data can be maintained at Gigabits per second. Currently the method has been used successfully on fibres up to 90km long, but just as distances for QKD over dark fibres have increased up to 250km, it is highly likely that these distances will be extended. After all, this is just the first announcement of the technique, and the one thing we know for sure is that technology has a habit of getting better very quickly.

Of course, nothing is ever quite as simple as it appears. Fibre optic cable suffers from effects that can work against this time slicing technique, no matter how accurate it is.? One such phenomenon is called Raman Scattering.? This is different from the more usual Rayleigh Scattering that people tend to envisage with fibre optic cabling, as they imagine the photons bouncing their way down the length of a glass fibre. In Raman Scattering, rather than bouncing inside the glass crystal of the fibre ?elastically? so that the photons maintain their energy and wavelength, a very small proportion of the photons (1 in 10million) are scattered so that their frequency is changed.? This causes detection problems.

However, the phenomenon is well understood, the models predicted to a high degree what was observed by the Cambridge team, and their system coped well, and was able to do the necessary error correction.? Indeed, the fact that the Raman scattering modelling was so well modelled in these tests suggests that the team have an environment that they can control successfully.? If you can predict the level of errors likely to occur, then you can make the necessary corrections.? You treat the errors as noise, which in the field of communications engineering is a well-trodden path.

More prosaic matters are what will hold up this technology.? For domestic use, there are few homes that have fibre running all the way to the homes router.? But, certainly in the UK, fibre is making an appearance at the end of many streets in cities across the nation, even though the final leg of the network is good old fashioned copper.? Governments are vying to roll out superfast broadband in their countries, which can only mean that fibre based networks will proliferate. Perhaps with them will come ?super secure? networking in the form of QKD.

Meanwhile, fibre networks are the basis for most Internet backbone providers, and many corporations.? With the costs now of the same order as much of the other equipment they buy for securing their networks, we must surely be about to see QKD become at least part of the network security landscape.

It appears the Cambridge research team have made a significant step forward, and whilst the journey is far from complete, I believe this further demonstrates that QKD is no longer just of academic interest.? It?s about to become a mainstream method of securing data networks.
