Best of 2011: How To Turn A Laser Into A Tractor Beam?

How To Turn A Laser Into A Tractor Beam


Physicists work out how to generate a backward pulling force from a forward propagating beam


A photon has a small momentum which it can impart to anything it hits, as Arthur Compton and Peter Lebedev discovered at the beginning of the last century. We now know that photons can be used to push anything from electrons to solar sails.

Today, Jun Chen from Fudan University in China and a few pals demonstrate the counterintuitive result that photons can pull things too. In other words, they've worked out how to generate a backward pulling force from a forward propagating beam.



Chen and buddies say this is possible when the system meets two conditions. First, it works only for beams in which the momentum in the direction of propagation is small, as is the case for beams that merely glance off an object. Second, the photons must simultaneously excite several multipoles within the particle, which scatter the beam.

If the scattering angle is just right, the total momentum in the direction of propagation can be negative, meaning the particle is pulled back towards the source and the light becomes a tractor beam.

This must not be confused with various "optical tweezer" type mechanisms in which particles trapped in a beam follow the intensity gradient of the light. In this case, the particles always reach some point of equilibrium where the intensity reaches a maximum.

Chen and co's new force works when there is no gradient. Given the chance, their tractor beam will pull a particle all the way back to the source.

That's a handy additional tool in the nanomanipulator's box of tricks. "This may open up new avenues for optical micromanipulation, of which typical examples include transporting a particle backward over a long distance and particle sorting," say Chen and co.

This is a theory paper so there's one piece of the puzzle left to fit. All they have to do now is demonstrate that their tractor beam works.

What is the need for work and play means?



The need for work and play

WORKABLE TIPS By PAUL KAM

Employers may not take too kindly to the current generation of employees who see a great need for work-life balance.

THE Human Resources manager looked up from the stack of papers in front of him and asked the young applicant why there was a gap from the time of his graduation and his work application. She took a few seconds to think before she gave a slight shrug and replied that she needed time and wasn’t sure of the jobs she wanted to apply for.

Then to justify her answer, she said that her mother financially supported her during that period.

The manager then asked her if she had any questions about the company since she had stated in her resume that she was looking “to grow her career and find the right company”.

An interviewer would be more impressed when a young applicant talks about her commitment towards her job instead of explaining the need for work-life balance.
 
She queried if it would be a nine-to-five job and added that she would not be able to work on weekends as she had church commitments.

I must say that she should not have responded in that manner as it was not appropriate.

This highlights the lack of drive and determination of the individual and raises doubts about the applicant’s commitment towards the job.



“Gap year” is a trendy term tossed around, and one commonly associated with the privilege of an affluent graduate. Indeed it means taking that fully financially supported time off for soul- or career-searching.

On the other hand, if the applicant had said she had taken the year off to gain working experience in the field she was planning to enter and to be sure that it was what she wanted, it would paint an entirely different picture.

In the present job market, employers are looking to hire people with more than just paper qualifications. Usually those who can afford to take a gap year to gain working experience and to determine their career path, would have an edge.

However, it has to be communicated in a manner that does not connote that a person has no direction or is not trying hard enough to look for a job and therefore making an excuse.

The other “demand” that interviewees tend to naively convey is work-life balance. This has to be earned and should not be considered a right of any new employee. In life, one needs to strike a balance.

Too much of one thing means less of another. Success is about hard work.

It is impossible to find an individual who has achieved success in the corporate world, or any other field by working regular hours, enjoying a five-day week and taking the contractual 14 or 21 days off to see the world.

Work-life balance should be considered a juggling act of the mind, and not the physical hours of work. In developed countries, there is great emphasis on work-life balance, so much so that some executives believe it is their right to demand that they work no more than eight hours a day, and yet be able to lead the lifestyle of many wealthy people.

I have been told by young travellers around the world about how they could afford to go on their journeys as there were apparently no limits to the number of credit cards they could obtain! However, recent surveys have also highlighted the number of bankrupts who were below the age of 30!

Having a work-life balance is not something that is totally unacceptable, but if I were in my 20’s and speaking to a prospective employer, I would keep my other priorities that are not work-related expressedly silent at the job interview. Employers are fair but like all human beings, they would like to believe that it is the job that is your most important priority at that point of time.

To me, work-life balance is not about equally distributing your time between work and personal life. It means being able to find the time to relax and do the things you love without compromising your work responsibilities.

I would also highlight to my employer of my objectives and goals for work life and social life and show how they complement each other. Find that balance and tailor your career for success.

Beggars banned from French popular tourist hotspots



Paris bans beggars from popular tourist hotspots

The glittering Christmas window displays in Paris's luxury stores are often offset by a shivering person begging for coins nearby, huddled behind a cardboard sign saying "hungry".

French authorities have to decided to ban beggars from popular Christmas shopping streets and tourist hotspots over the Christmas period
Authorities in Paris have introduced a controversial ban on beggars in several parts of the French capital, in a move they say is aimed at protecting foreign visitors. Police have been ordered to arrest or fine 'aggressive beggars' in popular shopping locations and tourist hotspots.

The ban was first introduced on the Champs Elysée, intially from September until January, but has now been extended to next summer. Other no-go zones include the areas surrounding the Galeries Lafayette and Printemps department stores, as well as the Louvre museum and Tuileries Gardens.

The ban is said to target beggars organised by Mafia gangs. Three hundred cases of illegal activity, including fraudulent money making petitions, have already been reported over the past three months on the Champs Elysée.

The move has faced criticism from the Paris' socialist mayor, Bertrand Delanoë. He says it is a 'PR stunt' designed to stigmatise part of the population. He added that fighting poverty with repression and fines at such a time when the government is failing its own obligations to house vulnerable young people and provide emergency accommodation, is shocking.



Paris bans beggars from most popular shopping and tourist hotspots

French authorities claim no-go zones aim to stop pestering of foreign visitors by 'delinquents' run by criminal gangs 

By Angelique Chrisafis in Paris - guardian.co.uk

With the French economy in crisis and the looming spectre of another recession, Paris's poor and homeless people are more present than ever in doorways and metro entrances. Campaigners have demanded action on the country's housing crisis. Instead President Nicolas Sarkozy has launched a war on beggars, setting himself against Paris's popular mayor.

Sarkozy's interior minister and long-time right-hand man, Claude Guéant, has issued a series of decrees banning begging around Paris's most popular Christmas shopping and tourist spots. He says arresting and fining beggars is crucial to stop foreign visitors being pestered by begging "delinquents" run by organised mafia gangs.

The Champs Elysées was first on his list with a begging ban from September to January, which has been extended to next summer. Now two more Christmas begging no-go zones have been created: around the famous Galeries Lafayette and Printemps department stores, as well as the Louvre and the Tuileries Gardens.

Critics call it the latest round in Sarkozy's campaign against Roma and Gypsies. Guéant claimed that the anti-begging decrees were part of a "merciless fight" against "Romanian criminality".

He said Romanian criminals accounted for one in six appearances in Paris courts and half of those arrested were minors. The anti-begging policy targets practices such as collecting money for bogus petitions, said to be carried out by Roma girls and teenagers.

Guéant has contracted 33 Romanian police officers to help the Paris force round up beggars on the Champs Elyssés. He said of the 300 cases of illegal activity recorded in three months on the Champs Elyseés, almost all were Romanian nationals, adding that organised crime networks were "particularly cruel".

But the Socialist mayor of Paris, Bertrand Delanoe, France's most popular politician, called it a cheap "PR stunt" designed only to "stigmatise part of the population". He said: "Wanting to fight poverty by repression and fines is shocking at a time when the state isn't fulfilling its obligations in housing vulnerable young people or providing emergency accommodation."

He said Guéant was targeting some of the city's poshest areas while ignoring real problems in other neighbourhoods.

With four months until the presidential election, Sarkozy's party is prioritising security and crime in an effort to win back voters who have crossed to Marine Le Pen's extreme-right Front National.

Last year, Sarkozy caused international outrage when he linked immigration to crime and promised to expel Roma migrants and destroy illegal camps. The number of Roma in France has not changed since the destructions of the camps but NGOs warn they now live in greater poverty with a climate of fear and intimidation towards them.

Anti-begging decrees have long caused controversy in France, with one rightwing mayor outside Paris criticised in 2005 for a summer ban on homeless beggars because they "smelt offensive". Temporary anti-begging rules have been put in place in cities from Marseille to Boulogne, some challenged in court by human rights groups.

Guéant, recently dubbed "the voice of Le Pen" by the leftwing Libération, is also under fire for this latest promise to cut legal immigration to France, limiting the rights of non-EU graduates to stay in France after their studie

Europeans migrate south as continent deepens into crisis



Helen Pidd in Berlin guardian.co.uk

Tens of thousands of Irish, Greek and Portuguese people leave in search of a new life as the eurozone's woes worsen

Since its conception, the European Union has been a haven for those seeking refuge from war, persecution and poverty in other parts of the world. But as the EU faces what Angela Merkel has called its toughest hour since the second world war, the tables appear to be turning. A new stream of migrants is leaving the continent. It threatens to become a torrent if the debt crisis continues to worsen.

Tens of thousands of Portuguese, Greek and Irish people have left their homelands this year, many heading for the southern hemisphere. Anecdotal evidence points to the same happening in Spain and Italy.

The Guardian has spoken to dozens of Europeans who have left, or are planning to leave. Their stories highlight surprising new migration routes – from Lisbon to Luanda, Dublin to Perth, Barcelona to Buenos Aires – as well as more traditional migration patterns.

This year, 2,500 Greek citizens have moved to Australia and another 40,000 have "expressed interest" in moving south. Ireland's central statistics office has projected that 50,000 people will have left the republic by the end of the year, many for Australia and the US.



Portugal's foreign ministry reports that at least 10,000 people have left for oil-rich Angola. On 31 October, there were 97,616 Portuguese people registered in the consulates in Luanda and Benguela, almost double the number in 2005.

The Portuguese are also heading to other former colonies, such as Mozambique and Brazil. According to Brazilian government figures, the number of foreigners legally living in Brazil rose to 1.47 million in June, up more than 50% from 961,877 last December. Not all are Europeans, but the number of Portuguese alone has jumped from 276,000 in 2010 to nearly 330,000.

Gonçalo Pires, a graphic designer who has swapped Lisbon for Rio de Janeiro, said: "It's a pretty depressing environment there [in Portugal]." In Brazil, by contrast, "there are lots of opportunities to find work, to find clients and projects".

Joy Drosis, who left her Greek homeland for a life in Australia, expressed similar motives.  "I had to do something. If I had stayed in Greece, we were all doomed," she said. "I'm lucky that I can speak the language: many others can't."

The key moment in this southerly migration may have come last month, when the Portuguese prime minister, Pedro Passos Coelho, made a humbling visit to Angola, begging for inbound investment. Just 36 years after the end of Portuguese colonial rule in Angola, its president was ready to show mercy.

"We're aware of the difficulties the Portuguese people have faced recently," said José Eduardo dos Santos. "Angola is open and available to help Portugal face this crisis."

But the Portuguese making this move will not have it easy: life expectancy in Angola is still just 39, compared with 79 in Portugal, and crime is rife.

In Ireland, where 14.5% of the population are jobless, emigration has climbed steadily since 2008, when Lehman Brothers collapsed and the bottom fell out of the Irish housing market. In the 12 months to April this year, 40,200 Irish passport-holders left, up from 27,700 the previous year, according to the central statistics office. Irish nationals were by far the largest constituent group among emigrants, at almost 53%.

The Guardian spoke to one Dublin under-19s football and hurling club that had lost eight out of 15 players in the past 18 months. Most of the nascent sports stars had headed to Australia. Experts believe the exodus will increase, given the £1.4bn tax rises and austerity measures just announced. The thinktank the Economic and Social Research Institute (ESRI) forecast this month that 75,000 people would emigrate from Ireland in 2012 .

For departing Greeks the top destinations over the years, according to the World Bank, have been Germany, Australia, Canada, Albania, Turkey, UK, Cyprus, Israel and Belgium.

Skilled Greeks are particularly likely to leave: as an example of what can happen, 4,886 physicians emigrated in the year 2000 (the last year for which the World Bank's Migration and Remittances Factbook cites data for departing doctors), meaning the country lost 9.4% of its doctors in that single year.

The World Bank gives the number of immigrants living in Greece as about 1.13 million in 2010, around 10% of the population. Most have come, over the years, from poorer countries such as Albania, Bulgaria, Romania and Georgia, it is likely that the majority of new arrivals lack the skills to replace the emigrants.

• This article was amended on 22 December 2011 to delete a sentence reading: "In 2010, 1.21 million people emigrated [from Greece], according to the World Bank, equalling 10.8% of the population." This was actually the total "stock" of Greeks said by the World Bank to be living overseas as of 2010, not the number who emigrated in that year. Also deleted was a reference stating that "1.3 million people arrived [in Greece] in 2011". This was the total "stock" of immigrants said by the World Bank to be living in Greece as of 2010, not the number who arrived in that year. A sentence saying that 4,886 physicians emigrated from Greece in 2010 has been corrected; the year was 2000.

Tech CEOs 2011: The best and the worst



by Charles Cooper, CNET

Armchair critics of the world rejoice. It's time to select the year's best and worst tech CEOs. It's a judgment that some no doubt will lambaste as arbitrary, even biased. On both counts we plead guilty. So if you have candidates for either category, or take issue with our choices, add your voice in the talkback section below. 

THE HEROES
Steve Jobs and Tim Cook 

Skip to the next section if you're thoroughly sick of reading about how Apple keeps hitting the ball out of the park. Truth be told, it was more fun in the mid-1990s when Apple was Silicon Valley's running soap opera. Nowadays the company operates with the sort of steamroller efficiency epitomized by the 1927 New York Yankees led by Babe Ruth and Lou Gehrig. And for that, you have to credit the CEO tandem of the late Steve Jobs and his successor -- and alter ego -- Tim Cook.

Jobs may be gone but his influence at Apple remains in the management team and product design philosophy that he left behind. Even though illness forced Apple's legendary co-founder to relinquish the reins to Cook in late August, his half-year as CEO was still better than full-year performances turned in by most of his peers. This wasn't an overnight handover. Whenever Jobs needed to take a step back, Cook was in the unique position of receiving extended on-the-job training, and whatever rough patches he might have encountered were well hidden behind Apple's carefully constructed PR screen. All the while, Cook got to learn first-hand from the tech industry's master marketer how it's done.



What a shame Jobs wasn't healthy enough to introduce the iPhone 4S. How the fan boys would have swooned when he offered them the first look at Siri. Cook's not a matinee idol and he doesn't try to be. Maybe that explains the relatively muted reaction to what was otherwise a very successful product debut. Some quibbled that the lines in front of Apple stores were smaller than for previous releases. But the bloggers and reporters who get hung up by the different style are making a big deal out of the trivial. Like Jobs, Cook has offered the leadership that you'd expect from a strong CEO. He more than justified Jobs' confidence as Apple's iPhones, iPads and iMacs continued to sell at a torrid clip in the second half of 2011, sending the company's shares are up more than 17 percent year-to-date, beating both the Nasdaq index and S&P 500.

The question everyone is asking is whether Cook can muster the magic on his own now that he's flying solo. Maybe we'll find out the answer in 2012. But so far, this rates as one of the most seamless managerial handovers in corporate history. And one of the most successful.

Mark Zuckerberg

Here's one way to think about how entrenched Facebook has become in the cultural lexicon: When someone decides they actually want to leave everyone's favorite social network grid, this now qualifies as "news." That is no small accomplishment. Even though Google now offers its own rival service, Facebook remains by a wide margin the preferred social network for revelers, revolutionaries, and just plain folk posting their musings, pictures, and videos uploads.

Wall Street has apparently decided that Facebook is not of this world, according it a pre-IPO valuation now north of $80 billion. But somehow the peanut gallery remains reluctant to give Mark Zuckerberg his full due for building a magnificent platform. Yes, he's profiled in business magazines and gets sought out for interviews by everyone from Charlie Rose to "60 Minutes." But when you listen to discussions of the great CEOs of Silicon Valley, you're more likely to hear mention of John Chambers, who had Cisco buy the company that makes the Flip video camera for $590 million and then shut the division less than two years later. The worst Zuckerberg ever did is get sloppy with privacy controls, a faux pas that some within the blogosphere may never forgive.

But as 2011 closes, it's time to give it up for the Z-man. Through the years he has remained true to his vision and resisted sundry offers to sell out. Back in 2006, when he was approached with a $750 million offer, more than a few people thought he should take the money and run. Who was Zuckerberg and what was Facebook to think they could outrun then-juggernaut MySpace? But five years later, MySpace is irrelevant, while Facebook has over 750 million active users and earned $500 million on $1.6 billion of revenue during the first half of 2011.

Like Bill Gates, an entrepreneur who managed very well as CEO at a young age, Zuckerberg is growing into the role (helped in no small part by his able No. 2, Sheryl Sandberg.). The best example came this fall when he put a potentially distracting privacy fight with the government in the rear view mirror instead of venting publicly about government persecution. He's familiar with Microsoft's less than happy experience battling Uncle Sam and wisely ordered Facebook to strike a deal with the Federal Trade Commission that should put this issue to bed.

Zuckerberg can't go on auto-pilot. His biggest immediate challenge, of course, comes from Google, which launched its Google+ service in July and passed the 40 million user mark in October. Facebook has to keep pushing. It did a nice job with Timeline, the new profile design that finally went live last week. And with an eye toward avoiding further complaints about user privacy, Facebook also rolled out a useful tool called Activity Log which may go down as one of the site's most important additions since the inclusion of the News Feed.

The coming IPO, presumably sometime in 2012, will be a barometer of Zuckerberg's success, as well as the event of the year's tech calendar. And who knows what the future holds? Is it altogether nutso to imagine Facebook bringing out its own search technology, one that could sort through a gold mind of data about social interactions? Zuckerberg is aiming high, and Facebook is already a good part of the way there. This is how legacies get created. If it all works as Zuckerberg hopes, then maybe that $80 billion valuation will turn out to be on the low side. Scary but true.

Larry Page

In Google's 2004 pre-IPO filing with the SEC, co-founder Larry Page sent prospective shareholders a Monty Python-like message that he wasn't interested in conducting business as usual.

"Google is not a conventional company. We do not intend to become one."

A bit full of himself, sure, but now that the proverbial buck stops at his desk -- he became CEO in April -- Page has had an opportunity to back up his words. Though his brief reign, this much is clear: While he may not be an unconventional CEO, Page has ably handled the awesome responsibility that he sought out. He set the company on a new course with the blockbuster announcement of a $12.5 billion deal for Motorola Mobility (a deal that gives Google more than 17,000 patents and will prove useful now that Apple is trying to nuke Android in a court case). Meanwhile, Android continues to grow by leaps -- according to Nielsen, it now powers about 40 percent of smartphones -- while Google's search dominance remains unquestioned. The company also made a successful entry into social networking with Google+, which finally offers Facebook its first serious competition for advertising dollars and user attention. Wall Street likes what it's seen. On the day Page took over, Google's shares closed at $587.68; with less than a couple of weeks left in the year, they're hovering around the $630 level.

By all accounts, Page's accession to the top job -- technically this is his second turn as CEO, though his first as the head of Google as a public company -- has been annotated by drive and energy. He wants to accelerate Google's corporate DNA, and in the near term, that may be his biggest challenge. The flip side of being big and successful is the spread of corporate sloth (as both Microsoft and IBM veterans can attest). With around 25,000 employees at Google, this is no longer a scrappy startup and it's become tougher than ever for good ideas to bubble up from the ranks and get proper consideration. That's why Page has winnowed the number of projects Google's engineers are working on, focusing their efforts on the areas where he thinks there's the best chance for the biggest returns.

OK, how difficult can it be to sit at the top of the mountain, take in your immense kingdom, and bloviate in SEC docs about being unconventional? In fairness, it's not as easy as it looks, so give Page deserving kudos for not screwing up what continues to be one of the most vibrant tech companies around. We're often reminded of the spectacular success stories registered by the likes of Bill Gates and Steve Jobs (his second time at the helm more so than his first go around) but any fair recording of CEO-founders includes no shortage of flameouts. Remember George Shaheen at Webvan.com, Philippe Kahn at Borland, and Ted Waitt at Gateway, to name a few? All were smart guys and their companies were once the toast of the town. Then the good times ended and they couldn't reverse the slide. If Page turns out to be as good as we think, Google's CEO won't ever find himself facing that sort of predicament.


THE GOATS Reed Hastings

Yesterday's hero can turn into today's goat in the amount of time it takes to launch a press release. Just ask Netflix CEO and founder Reed Hastings, who must still be wondering if it was all a nightmare.

Up until this year, Hastings was an Internet rock star, lauded for having changed the way we consume movies and television shows. Netflix was an easy-to-use service priced at the sweet spot. Consumers flocked to it. Wall Street sang its praises. But it all came a cropper in September when Hastings executed the sort of maneuver that one might have expected from F-Troop.

It wasn't just the 60 percent price hike on one of Netflix's most popular plans that got peoples' dander up. Netflix also planned to split into two parts: One unit named "Qwikster" would mail DVDs to subscribers, while the other would continue to focus on streaming movies over the Internet.

This turned out to be a public relations disaster. Even though the price increase would impact only subscribers who used both the streaming and mail-order sides of the business, the announcement left Netflix loyalists steamed. Two separate websites with two billing systems and two names? If there was a higher logic at play, it escaped most people. The reviews were uniformly lousy and Netflix became the butt of late-night TV hosts' jokes. Wedbush Securities analyst Michael Pachter summed up the general reaction with this icy observation to a reporter from USA Today: "They raised prices. They offered lower-quality content, and they made it more complicated." Within three weeks Hastings reversed the Qwikster decision and publicly apologized for having "slipped into arrogance" (though Netflix kept the price increase in place.) But the apology was too late to repair the damage. During the third quarter, 800,000 subscribers responded to the Qwikster fiasco by dumping the service. Shares of Netflix, which earlier in the year poked above $300, have since fallen to the $70 range.

People have short memories and this isn't necessarily the end of the world for Netflix. Fans do return. Think Bob Dylan and his move to electric guitar. After the initial freak-out, most of the faithful got over it. Nothing here rules out that kind of rebound for Hastings -- as long as he avoids hitting another sour chord. At that point, Neflix really could be left blowing in the wind.


Leo Apotheker and Meg Whitman

Leo Apotheker

In our quiet moments, it's reasonable to wonder whether some mischievous warlock left the curse of the cat people on Hewlett-Packard.

Carly Fiorina's years were marked by corporate drift and tumult. Her replacement, Mark Hurd, was ousted in an expense-fudging scandal involving a former soft-porn actress. In between, there was a bizarre novella in which corporate officers trying to plug a leak ordered investigators to spy on journalists.

But nothing -- and I mean nothing -- compares with the brief and utterly feckless tenure of one Leo Apotheker, hired in November 2010 to replace Hurd.

Apotheker was a highly regarded software executive who had been chief executive of SAP AG. Although he had little experience as a hardware executive, the company hoped he could take the management skills he had picked up over the course of his long career and apply them to the job at hand. It was only much later on that we learned most members of HP's board of directors had never even met Apotheker before voting to hire him. That's what you get when the company is overseen by what a former board member has described as the "worst" board of directors in the history of business. But I digress.

After 11 months as CEO, Apotheker got the boot and HP, once one of Silicon Valley's storied company, was reduced to a laughingstock. The chronology played out over the summer, when Apotheker announced that HP would kill off the TouchPad tablet computer, which had only recently debuted. He also canceled a crop of phones and products based on Palm's WebOS operating system. He was also convinced HP would be better off selling the PC business, a $30 billion division which at the time still enjoyed big market presence.

His plan now is easy to mock. But Apotheker had a strategy to remake HP into something resembling his former company and specialize in catering to enterprise-sized companies. On the surface, at least, it was intriguing. After all, the idea of jettisoning low-margin businesses to focus on software and service worked wonders at IBM under Lou Gerstner and Sam Palmisano. But it took time for those two to get all the pieces in place and plan IBM's exit from the commodity stuff.

In contrast, the clock was ticking for Apotheker right from the start. And with HP missing its financial targets, Apotheker quickly lost credibility with the financial community, making investors even antsier as HP's stock lost 40 percent of its value. He also lost credibility with another key constituency as the board grumbled at his poor communications skills (starting with the decision to kill the TouchPad) as well as the company's product direction. Rightly or not, Apotheker was labeled a zig-zagger with little feel for HP's hardware business. The board executed a mercy killing in September, replacing Apotheker with Meg Whitman. The former eBay CEO has since announced that HP would keep the PC business.

You can't make this stuff up.

RIM co-CEO Mike Lazaridis shows off the BlackBerry PlayBook.(Credit: BlackBerry PlayBook, Mike Lazaridis)
 
Jim Balsillie and Mike Lazaridis
 
After their company's latest earnings debacle, Research In Motion's co-CEOs James Balsillie and Mike Lazaridis announced they would take just $1 in salary. Given the collapse of this one-time tech darling, some shareholders may grumble these two are still being overpaid.

It's hard to believe how quickly RIM has collapsed. The company's stock has lost more than three-quarters of its market value in the last year while a myriad of app-hip mobile handset rivals have prospered. That's all the more remarkable given how we're talking about what once was the premier mobile device maker for businesses. Now RIM is a company that can't seem to keep up. With every new Android and Apple update, RIM promises a next-generation BlackBerry phone -- sometime in the second half of next year. Meanwhile, its PlayBook tablet has been turned into a bargain-bin product with RIM offering massive discounts.

Cue up Clayton Christensen and the perils of the innovator's dilemma, where one-time market leaders fail to capitalize on new waves of innovation. In the meantime, here's Lazaridis trying to explain why the on BlackBerry 10, the upcoming product RIM has touted as the basis for its superphone, is going to be delayed:
We need a highly integrated dual-core LTE platform.The processor we selected offers industry-leading power and efficiency, and also allows us to deliver the industrial design, that we believe is critical to the success in this market segment. This chipset will not be available until mid 2012. And as a result of this and certain other factors, we now expect our first BlackBerry 10 smartphones to reach markets in the latter part of calendar 2012. In the meantime, we believe that our strong BlackBerry 7 portfolio will continue to drive adoption of BlackBerry around the world.
One problem: In July, Lazaridis told shareholders that the BlackBerry 7 handsets were just "messaging" handsets compared to the "mobile computing" handsets slated to come out with the BlackBerry 10 software. Now the company's stuck with these same "messaging" handsets while the market keeps moving along. Sanford Bernstein responded to that performance by calling management "in complete denial of the situation" while another brokerage, Robert W. Baird, said RIM's U.S. business was "in a freefall."

There's a growing feeling that Balsillie and Lazardis, who share responsibilities for leading RIM, are congenitally conventional managers ill-equipped to handle an unconventional challenge. The situation has reached the point that some are even floating suggestions that RIM may need to consider dumping the BlackBerry if it's to survive. That sounds like a stretch but at this rate the situation is impossibly grim, with investors and customers holding onto faint promises of better times ahead. The fact that RIM has even reached this point constitutes Exhibits A, B, and C for the chorus of critics demanding new leadership.


Tim Armstrong

As an early user of AOL's dial-up service, I have to confess to a twinge of nostalgia each time I watch "You've Got Mail." That's about the only warm and fuzzy feeling AOL gives off these days as CEO Tim Armstrong seeks to find on a formula that will save the company from media also-ran status.

Give the man credit for believing in a strategy. But after two years making the same pitch, the question is whether he's got the right strategy. Armstrong is an online ad sales guy -- he was Google's president of the Americas operations -- and has gone shopping for new content that AOL's ad sales team can sell against. Like Yahoo, AOL has a legacy business in the form of its dial-up operations which, remarkably, still throws off a lot of cash each quarter. That's allowed Armstrong to fund his bet that that content will create scale when he acquired the Huffington Post for $315 million as well as TechCrunch for a reported $30 million. It's still too early to say how those deals are going to work out for AOL though they were grand slams for the two blogs' creators, Arianna Huffington and Michael Arrington, who sold at the peak. The other big hope is Patch, the company's network of hyperlocal Web sites. AOL this year has sunk $40 million into Patch on top of the $75 million that it spent on the project last year. Good money after bad? Not according to Armstrong, who has predicted that Patch will start generating a profit by the end of 2011.

But despite adding a collection of works in progress, AOL has failed to distinguish itself from the pack. AOL may argue that its content Web site pickups will help boost traffic and revenues in a meaningful way but it is unclear whether traditional remedies for a traditional media company will provide the needed fix. Wall Street has not bought the story. With Armstrong scheduled to take home a total annual compensation package of $1 million, AOL's stock plummeted from nearly 25 earlier in the year to the mid-teens.

On top of that, Armstrong's reputation as a leader suffered when he was unable to effectively resolve the summer soap opera involving Arrington and Huffington. After losing a turf war, Arrington very publicly left AOL; he was soon followed out the door by several key staffers - including, most recently, TechCrunch CEO Heather Harde. But that was just a circus sideshow to the central question about whether Armstrong has what it takes to turn AOL into a money maker. Already calls are coming to split the company into pieces and jettison the units that aren't adding to growth. How long before some of those same voices begin asking why Armstrong should escape paying the same penalty exacted from Carol Bartz when she failed to revive Yahoo? After all, you can only be in turnaround mode for so long.

Cheating Spreads Like Infections In Online Mulitplayer Games




Cheating Spreads Like Infections In Online 

Mulitplayer Games

If you have friends who cheat, you are more likely to become a cheater, according to computer scientists who say this can be used to label you as a potential cheater kfc 12/23/2011


Online gaming is a multi-billion dollar industry that serves millions of gamers around the world. But it suffers from a problem: cheating. Some players give themselves an unfair advantage by using 'cheat software' to see through walls or to automatically shoot moving characters

Cheat software is banned but in the sophisticated economies that have evolved in these worlds, cheaters can generate a significant income by using it. The developers of multiplayer game APB Reloaded, estimate that cheatmakers can make up to $50,000 per month.



The trouble, of course, is that cheats poison the experience for legitimate players. The temptation is then for all players to cheat which leads to an uncontrolled escalation of illegal activities and the eventually destruction of the gaming environment.

So gaming communities invest significant resources into finding and stopping cheaters. In the Steam Community, for instance, which has some 30 million users, cheats are clearly labelled so that other users can see them and so that servers can prevent them playing games from which they are banned (although they can play other games).

Cheaters cannot easily start new accounts because the games they buy are linked to their old accounts and access is non-transferable.

So an interesting question is how cheaters behave in this social network.

Today, Jeremy Blackburn at the University of South Florida in Tampa and a few buddies study a social network of about 12 million gamers on the Steam Community of which some 700,000 are cheaters.

What they find is interesting. First up, cheats stick together. The data shows that cheaters are much more likely to be friends with other cheaters.

Cheating also appears to be infectious. The likelihood of a fair player becoming labelled as a cheater in future is directly correlated with this person's number of friends who are cheaters. So if you know cheaters you are more likely to become one yourself. Cheating spreads like flu through this community.

Finally, being labelled as a cheat seems to significantly affect social standing. Once a person is labelled as a cheat, they tend to lose friends. Some even cut themselves off from friends by increasing their privacy settings

Blackburn and co say they've even seen newly labelled cheaters commit 'social suicide' by cutting themselves off from all their friends.

While this work gives a unique insight into the social behaviour of cheats, Blackburn and co say it also points to a new angle of attack for gaming communities hoping to stamp out cheating.

Their idea is to use the structure of the network to predict the likelihood that a given player will become a cheat in future. In other words, the number of friends who are cheats determine how likely this player is to becoming infected with the 'cheating virus' in future, so to speak. They say they expect to do more work on this in future.

Nobody knows exactly how the Steam Community developers detect and label cheats now. The details are strictly guarded, as would be expected in this kind of cat and mouse game.

But however it is done, the new method is a kind of pre-crime detection rather like the movie Minority Report. That's a dangerous avenue to tread. The labelling of individuals as potential cheats itself has significant moral, philosophical and legal implications that will need to be teased apart and examined before it can be employed in the real or virtual worlds.
