U. Ohydrates. States that Drone Crashed, Refuting Iran's Maintain

WASHINGTONU. Ohydrates. officers feel the actual downed criminal drone at showcase on Iran crashed plus smashed right into a variety of bits, Canadian Jakke along with the Iranians reassembled them to produce the application turn up as if the application arrived at in one piece.

Officials likewise feel the actual Iranians repainted a drone, possibly so that you can obscure impairment achieved towards shape with the planes. Within the Iranian video clip, the particular drone seems whitened, while the exact you are smokey barbecue grilling overcast, many people mentioned.

Iranian authorities yesterday proved video clip in whatever some people reported seemed to be all the downed drone, this RQ-170 Sentinel. They've got variously professed they golf shot it again downward and also remotely skyjacked the item prior to when you your art without trouble.

The stealth drone was created for your Atmosphere Compel, Moncler Jacket though was basically going beneath recognition with the Middle Mind Service while their distant pilots forfeited deal with from it delayed a couple weeks ago, claimed many Ough. Ohydrates. officers.

With on the list of most-sophisticated Ough. Ohydrates. criminal airplanes right now around Iranian hands and fingers, You. Ohydrates. authorities carry on deliver the results to help you take a look at the amount of Oughout. Ohydrates. cleverness capacity had been severely sacrificed. Iran's capability to reassemble the actual drone plus wear it display screen seems to have instigated You. Ohydrates. congress in order to check with how come typically the unmanned drone didn't have enough an element this brought about the software towards self-destruct in case the idea malfunctioned, some sort of congressional established stated.

U. Ohydrates. officers accustomed to that Western comparability with the unpleasant incident powerfully fight Tehran's record along with declare the particular start sacrificed command from the art. "They wouldn't commandeer this plus help it again for the land surface, inch stated a strong Federal government endorsed. "It crashed, and in addition they place it backside mutually to create it again start looking overall, such as a bigger picture becoming decide to put once again together with each other. "

U. Ohydrates. authorities stated people assume typically the aeroplanes split in two and up products while the idea crash-landed. That test will be based upon an evaluation from the shots for Iranian telly together with the Sentinel's type needs along with brains coming from several other suppliers.

The indisputable fact that the actual drone crashed proposes the application undergone alot more ruin in comparison with is normally advocated from the Iranian online video, Sito Moncler it is definitely unsure simply how much colon problems appeared to be performed towards the work.

Administration and also army officers contain believed that Iranians would probably study smaller because of items of your planes, Trillium Parka that they state can not be without difficulty inverted constructed. Authorities stated a drone concept is consistently increasingly being improved, which could reduce a data benefits with the drone that Iranians currently have.

Some congress evaluating the actual tv show, even so, dilemma these kinds of claims.

"It won't are already very difficult to place the application spine mutually, inch mentioned 1 congressional formal. "It's an enormous damage. "

Lawmakers possess began his or her report on how come typically the drone malfunctioned.

The Federal government viewed as submitting an important to save power team so that you can covertly regain and / or damage your downed drone prior to the Iranians identified the application, yet eventually officers ditched taking that approach for the reason that at the same time precarious.

To Replicate or Not To Replicate?

Checking other people's experiments is essential to the process and progress of science,Canada goose but there's a catch: Scientists have to earn a living. They have to establish careers. Replicating other people's data wins little prestige and few job offers.

How should early-career scientists deal with this asymmetry between scientific and career-development imperatives? When their adviser asks them to repeat someone else's experiment,Canada goose parka what should they do, and how should they think about what they're doing?

They should adopt a broader view of replication and look for the opportunities it presents, because replicating other scientists' work is a necessary step in advancing your own research in the same area. And that, in turn, is an essential career-development activity.

"It's not that there's an activity called ‘science’ and there's a separate activity called ‘replication,’ " says Gary King, director of the Institute for Quantitative Social Science at Harvard University and a vocal proponent for data sharing and replication.Canada goose outlet "There's this general misconception that replication is this activity for low-level academics, but actually it's what the best people do."
The trick, he says, is in seeing replication not as an end in itself but as a means for acquainting yourself with the methods used in a study, the original author's line of thinking, the complications he or she must have faced, and the solutions they devised to those problems. Replicating an experiment, or even the whole study, can be useful for young scientists who are learning their way around the bench or lab,Canada goose expedition parka he says.

"The advances in science over the last several hundred years have not come only from individual scientists, … [they've] come from scholars and scientists working in concert with each other and the community," King says. "If you're going to start a new project … the first thing you should do is get up to the cutting edge of the field, and by far the best way to do that is to take the best article and to replicate it."
Victoria Stodden,Canada goose trillium parka an assistant professor of statistics at Columbia University, agrees with King. Stodden serves on the National Science Foundation's Advisory Committee for Cyberinfrastructure and has given numerous talks championing better data sharing and replication practices. "I think it's important if you're building on results in a field to replicate them, to be able to not just verify them but to understand how these results actually came about," she says. "That makes you a little more educated in terms of how you'll be able to build on those results. It's easier to extend the science if you know how it got to the place where it is today."

To that end, both Stodden and King require their undergraduate students to form teams and replicate current studies in class. It's a good way to instill the importance of data replication, they say, and to illustrate that in order to develop new ideas, scientists must first thoroughly understand the field in its current state.

King says that by working through the original author's paper and discovering the "enormous number of small decisions" he or she made that aren't explicitly described in the methods section, young scientists can often identify entirely new questions that the original author never thought to address. "The best papers that have come out of my class are not the ones that just say, 'I replicated the article in this journal and it came out the same,' or, 'it came out different.' Those are boring," he says. "The ones that are really interesting start that way and then think of a question that wasn't asked in the original article, or improve the methodology and produce a different answer."
King gives an example of a group of students a few years ago who were working to replicate a paper about presidential election campaign strategies by a respected social scientist -- King declined to name names -- and after following the paper's methods section to the letter came up with vastly different results. "It wasn't even close. It wasn't anywhere near where it should have been," he says. The students spent the next several weeks tweaking this or that variable and checking their own work to determine where the error was coming from.

At 2 o' clock one morning, King received an excited e-mail from the students. They'd figured it out. It seems the original author -- someone King describes as highly cited -- had mentioned in his methods section that he'd applied two statistical corrections to his data to account for a selection bias. But the analysis only matched the paper's figures and graphs if you ran the data without those statistical corrections; apparently, the author had forgotten to apply the corrections, even though he said he did. It was probably just an honest mistake by the author, King says, but the effects reported in the paper completely disappeared once the correct manipulations were applied. The students went on to publish their findings. "It's only by people checking what we're doing that we can figure out what we really discovered originally," he says.

Richard Muller, a physicist at the University of California, Berkeley, who is leading a team of climate scientists in a high-profile replication of decades' worth of climate data and analysis, says that developing new ideas while doing a replication study is the only thing that can make them worthwhile for young scientists. Over the years, he's seen a number of ways in which replication studies can go wrong in career terms. He points to the Fleischmann–Pons cold fusion experiments of the late 1980s. Early on, a number of young scientists set out to replicate the attention-grabbing findings of Martin Fleischmann and Stanley Pons, and many of them did just that: They "verified" that Fleishmann and Pons had succeeded in achieving nuclear fusion by electrolyzing heavy water, he says. Within a couple years, many more studies had proven them utterly wrong. "People who replicated the experiments lost their reputations," Muller says, "while those who failed to replicate them got no credit whatsoever."
Muller's advice to young scientists is to limit replication studies to those that help move forward your own and your lab's novel research."There's a lot of replication that you do as a matter of course," he says. "When people discover a new elementary particle and determine its mass and how you produce it, for the next year people will be producing it to be able to use it." That kind of replication is valuable and pays dividends to young scientists. But doing a replication study just for the sake of checking whether the original author made a mistake isn't smart, he says.

Even in the case of Muller's recent verification of the findings from existing climate models, "we're still not published yet," Muller says. Despite the effort's high profile, a couple of journals have turned his paper down because, Muller says, they felt it didn't add anything novel to the existing literature. That illustrates why younger, less established scientists should avoid doing "pure" replication studies. Muller says his team's experiment is a little different from a traditional replication study, since they used new tools to analyze the same data.

Muller, King, and Stodden all say that with very few exceptions, if you replicate a study, you should limit its publication to a footnote -- no more -- in a paper reporting an original result. While occasionally a journal will publish a replication study by itself, they say, doing so is usually a waste of time and resources that would be better spent on original research that will further your career. Says King: "There's an enormous amount of information in any dataset that was worth publishing to begin with, and there is probably some other discovery to be made in there. It's good career advice to go find that thing."

ZoneAlarm Updates Free Firewall

Antivirus software alone won't prevent your computers and devices from getting hacked—firewalls add one extra layer of defense against malware.

Fortunately,Tods Scarpe Check Point has updated its long-free ZoneAlarm firewall protection to include a new user interface and faster installation process compared to version 9.2, which was released last year.

We haven't tested it yet, but ZoneAlarm Free Firewall 2012 works with any AV package to block cybercriminals, spyware, bots,Tods Borse and more. Check Point says the firewall basically renders your PC "invisible" to hackers; when malware is detected, the firewall kicks in an outbound protection layer that prevents cyber thieves from sending information back to host servers or distributing spam to your contacts.

The only difference between this and Check Point's firewall protection bundled in ZoneAlarm Antivirus + Firewall 2012, which costs $59.95 direct for three licenses, is that it doesn't contain "advanced download protection," which warns you if you're trying to download a malicious program, or the "OSFirewall,"Tod's which monitors programs for suspicious behavior. But apart from that, the firewall monitors all inbound and outband traffic, includes full stealth mode, kill controls, blocks phishing, and provides credit monitoring and alerts. It also allocates 2GB of free online backup.

You can download the firewall on zonealarm.com. Meanwhile, Check Point also offered up the nifty infographic below,Tods Shoes which explains to young and old just what firewalls do (click to enlarge).

Bit by Bit, Work Exchange Site Aims to Get Jobs Done

Jim Wilson/The New York Times

Philip Rosedale in Coffee and Power's storefront office on Market Street in San Francisco.
SAN FRANCISCO — Philip Rosedale tried to change the nature of play with Second Life, a virtual world of colorful online avatars that got a lot of attention a few years ago. Expedition Parka 
Now he wants to change the nature of work.

While Second Life is still around, it never lived up to its hype. But Mr. Rosedale, 43, is back with a new business called Coffee and Power, where people buy and sell most any kind of task, like making Halloween costumes or writing sophisticated software.Trillium Parka

To prove his point that a work exchange could function, Mr. Rosedale built the software for his new company by hiring programmers from around the world and dividing up the work into about 1,600 individual tasks, from setting up databases to fixing bugs.

“We think it’s the new model for how software will be written,” he said. “It worked so well that we decided to extend it to all sorts of work.”

Coffee and Power has storefront space in a nondescript part of San Francisco’s Market Street where people can drop in and offer to do jobs or hire people for tasks. They can even start working together on the spot. Mr. Rosedale works upstairs, along with a handful of full-time staff members.Canada Goose

On a recent day, the public space had three groups of people making use of the human and laptop fuels behind the company name. The groups were working on software projects, business planning and tutorials.

As with Second Life, the business has a virtual currency for buying, selling or bestowing tasks as gifts. Coffee and Power takes a 15 percent fee for moving the money back into real dollars.

The site has been active since spring with little fanfare. It attracted fewer than 700 transactions, but is now starting to actively solicit buyers and sellers.

“About 25 percent of our site is needs, and the rest is offers,” Mr. Rosedale said. “We’ll need about 10,000 jobs before we know what the final balance is like.”

Other online services have similar ideas — Task Rabbit, Freelancer.com and Amazon’s Mechanical Turk among them. One of the striking things about these services is how inexpensive it is to get something done.

Translation services on Coffee and Power currently sell for $10 a job, and a bike messenger can be had for $15. Much of the time, the people involved are already in these professions and are looking to make a few extra dollars on the side.

Besides putting downward pressure on what people can charge, the low prices also raise questions about the quality of the services. That is one reason that Mr. Rosedale is publicizing that he used cheap labor to build his own site.

He paid about $200,000 to build Coffee and Power, he said, using an earlier version of the service called Worklist. Every step in the development process is visible on the site, including the amount people have been paid for their work. An Australian working under the name Lithium has earned $46,523 since January, for example.

Another test project, called Hudat, is an iPhone application that converts pictures of Facebook and LinkedIn friends into online flashcards. The idea is that a person can review images before attending a party. It cost $2,600 to build, a fraction of what work like this normally costs, and was built in two weeks. The process is open for anyone to see.

“We work on total transparency,” Mr. Rosedale said. “If you don’t want anyone to see what you are working on, this is not for you.”

Second Life, in its heyday, held similar promise. While it became notorious for sexual chatter, it has over the years attracted a Reuters news bureau, now defunct, as well as emporiums of several companies like American Apparel and Starwood Hotels. Cisco Systems also held meetings there. Second Life still exists, but is much quieter now, offering virtual currency, meetings and digital real estate, among other services.

While he is still chairman of Linden Lab, the company that created Second life, Mr. Rosedale talks about that venture in the past tense.

“The problem with creating an immersive 3-D experience is that it is just too involved, and so it’s hard to get people to engage,” he said. “Smart people in rural areas, the handicapped, people looking for companionship, they love it. But you have to be highly motivated to get on and learn to use it.”

Mr. Rosedale, who raised about $1 million for Coffee and Power from investors including Jeff Bezos, Catamount Ventures and Greylock Partners, sees the trend of breaking work into smaller pieces — both in software and for physical tasks — as one that will continue to gain traction.

“I would rather hire a kid in Brazil who is hungry for work for a project than hire a Stanford graduate,” he said.

Gaddafi buried in unmarked grave in Libya desert to avoid creating shrine

The belated finale for Muammar Gaddafi began on a marble slab in a car park and ended with a lonely burial in the desert far from the reach of family or foe.

After his body spent five days on gruesome display, Libya's new rulers finally decided late on Monday night to put Gaddafi to rest, capping a week of uncertainty about what to do with the slain despot's remains and closing an era of fear and infamy.

"We gave him all the Islamic rituals that we would give any Muslim," said the deputy chief of Libya's new governing council in Misrata, Sadiq Badi. "It was more than he would have given us, but we gave him a dignified end."

He was prepared for burial alongside two other corpses – his son Mutassim and his former military chief, Abu Bakr Younes, who had been holed up with him during the fall of Sirte.

Just before midnight, three Islamic holy men, all of whom have been imprisoned by rebels, along with three family members of the dead men, were taken from their cells in Misrata to a building on the outskirts of town.

The six men were told to wash the three bodies. Younes's sons, Osma and Younes, were allowed to clean their father, while the grandson of Gaddafi's sister, Sharif al-Gaddafi, had the task of washing his great-uncle. They were the only family members allowed near the bodies.

Libyan officials rejected repeated requests from the Gaddafi tribe in Sirte to hand over their patron and leader. Overtures from his wife, Safia, and daughter Aisha were also turned down.

Alongside the men were three sheikhs who the regime had used to help secure its 42-year grip. Khaled Tantoush, Medina Shwarfa and Samira Jarousi were loyal to Gaddafi until the end, their captors say.

They crouched at a cream-coloured marble slab, which was slick with water from a nearby garden hose. Nearby, three tables stood illuminated by a giant lamp, a generator purring next to them and uniformed rebels watching from the shadows.

The slab was outside a nondescript government building that like many others in Misrata had been ravaged during the civil war. It was purpose-built for washing corpses, an essential prerequisite for Islamic burials, almost all of which are conducted within 24 hours of death.

The extended time above ground had clearly taken a toll on Gaddafi's remains and Tantoush said preparing the dictator for burial was an unpleasant experience. For most of the previous five days, the decaying bodies had been displayed on blood-stained mattresses in a meat-packing crate, with thousands of people clamouring for trophy photographs.

The spectacle had stirred disquiet in Misrata and turned stomachs abroad. Libyan officials defended the display as a need for people of this traumatised country to find closure and to see for themselves that their 42-year ordeal was over.

"I didn't feel anything when I was washing him," said Tantoush. "I was just doing my duty as a Muslim. He was a person and he should be properly buried."

"Liar," muttered one of his jailers, Haithem Danduna, at Tantoush. "He is a chameleon," he added, pointing at Tantoush. "He was green until a week ago," in reference to the colour of the regime.

Appearing flustered, the sheikh continued: "It was a good thing what they did last night, allowing us to bury him. It was a good start of a new beginning. After we finished washing him we moved to the tables and we wrapped them in white, then prayed for them. The whole process took about an hour. The guards helped us move the bodies."

The whereabouts of Gaddafi's grave is a closely guarded secret in Misrata. Authorities here and elsewhere in Libya are anxious to avoid his grave site becoming a shrine for his supporters, or a target for his enemies.

Of his inner circle, only Gaddafi's long-term driver, Huneish Nasr, and Sharif were present at the burial alongside rebel guards. "We are not going to let him be remembered as a martyr," said Danduna. "He got a proper burial and now let the desert consume him."

Across town, at a cemetery for nameless victims of the war, gravedigger Salam Zwaid pointed a gnarled hand at the grey slabs behind him. "This is the best Gaddafi could have hoped for," he said, walking through the shallow graves, all of which were sealed by cheap concrete.

"He saw himself as the king of kings, someone who was better than all of this," he said. "But he was no god. He was a person and a bad person at that. No one should learn where he was buried."

Back at the prison, Tantoush claimed the burial could be cathartic for Libya, where Gaddafi's brutal end is still sinking in. "In the beginning I thought he was righteous and on the right path," he said in remarks his jailers insisted were self-serving. "And after 17 February every bit of news we got was wrong. We didn't know this was a real revolution.

"I was in Sirte and after a while we knew he was there. But I changed my support for him a month ago when they wouldn't let the Red Cross enter to treat the wounded. After that it all became clear.

"His death should wake people up. It is time to move on now. I hope people never find his grave. If they wanted to tell me where it was, I would not want to know. All Libyans should think the same."

Pictures of Gaddafi's corpse continue to be published in Libyan newspapers and shown on TV. Freshly painted graffiti on the streets of Tripoli – in Arabic and English – read: "Dictator Gaddafi sent a message to the Libyan people from hell, saying 'I am staying here.'"

Images were also circulating on the internet apparently showing Gaddafi being sodomised with a stick or metal rod. The footage was shot on a video on a mobile phone and includes sounds of gunfire and shouts of "Allahu akbar."

Towns with jobs galore... but no one interested in doing them, says damning survey of bosses

Many job seekers cannot even be bothered to turn up for interviews on time and lack 'the right attitude to work', a damning survey of employers revealed yesterday.
Despite unemployment rocketing to a 17-year high, nearly half of employers said they could not find the right person for a job when they have a vacancy.
They said candidates were hampered by poor literacy and numeracy.

Even if they have the right qualifications, they often lack 'soft' skills such as timekeeping and communication, according to the report by the British Chambers of Commerce.
More than 440 firms in Derbyshire and Nottinghamshire were asked whether they find it easy or difficult to recruit the right staff for a job. Unemployment in the East Midlands currently stands at 183,000.
Just 30 per cent said they find it easy – but 43 per cent said they find it quite or very difficult. When asked why candidates were wrong for the job, many bosses said they did not have ‘the right attitude towards work’.

Others said some job hunters were so lazy they could not even turn up for an interview on time.
George Cowcher, chief executive of Derbyshire and Nottinghamshire Chamber of Commerce, said: ‘A highly-skilled workforce is absolutely crucial to the success of any business.
‘But the results of this survey provide incontrovertible evidence of what our members have been telling us for some time.

‘Businesses want to expand, create jobs and develop their workforce, but are hampered by a lack of skills in the local labour market.’
Mr Cowcher said businesses believe that more needs to be done to help school leavers, young adults and the long-term unemployed.
He called on the Government to put skills and training at the ‘very heart’ of its growth strategy. 

Mr Cowcher said there were around 27,000 job vacancies in the region. Last month Dragons’ Den star Deborah Meaden said she could not recruit teenage apprentices for her textiles factory because they do not think manual labour is ‘cool’.
Last week a poll of some of Britain’s biggest firms, including HSBC, Santander and KPMG, found widespread despair with the quality of potential recruits.
Three in four bosses said school leavers and graduates lack the ‘basic skills’ needed to join the workforce, according to education charity Young Enterprise.
Another report, from the Chartered Institute of Personnel and Development, said employers had ‘concerns about the employability of young people’.
It found bosses prefer foreign workers to British school leavers because they have a more ‘positive’ attitude.
Yesterday a spokesman for the Department for Education said: ‘We share the concerns of many businesses that too many of our young people leave school without the skills needed for work, in particular in the basics of English and maths.’
