Silent Skype calls can hide secret messages









































Got a secret message to send? Say it with silence. A new technique can embed secret data during a phone call on Skype. "There are concerns that Skype calls can be intercepted and analysed," says Wojciech Mazurczyk at the Institute of Telecommunications in Warsaw, Poland. So his team's SkypeHide system lets users hide extra, non-chat messages during a call.












Mazurczyk and his colleagues Maciej Karaƛ and Krysztof Szczypiorski analysed Skype data traffic during calls and discovered an opportunity in the way Skype "transmits" silence. Rather than send no data between spoken words, Skype sends 70-bit-long data packets instead of the 130-bit ones that carry speech.












The team hijacks these silence packets, injecting encrypted message data into some of them. The Skype receiver simply ignores the secret-message data, but it can nevertheless be decoded at the other end, the team has found. "The secret data is indistinguishable from silence-period traffic, so detection of SkypeHide is very difficult," says Mazurczyk. They found they could transmit secret text, audio or video during Skype calls at a rate of almost 1 kilobit per second alongside phone calls.












The team aims to present SkypeHide at a steganography conference in Montpellier, France, in June.

Thousands stuck in China airport as country freezes






BEIJING: Thousands of angry passengers were stranded after heavy fog delayed flights at a Chinese airport early on Saturday, as the country was shivered through its coldest weather in almost three decades.

Ten thousand passengers were stuck in Changshui International Airport in the southern Chinese city of Kunming on Saturday morning after thick fog grounded more than 280 flights, state-run Xinhua news agency said.

Angry passengers stranded at the airport for more than a day struggled with airline staff, damaging computer equipment belonging to an airline, while police broke up scuffles, a photographer present at the scene late on Friday told AFP.

"The passengers were really furious, they kept going to the service desk to ask for information, but didn't get any answers," the photographer said.

Flights at the airport resumed on Saturday afternoon after the fog lifted, Xinhua said.

China is suffering its coldest winter for 28 years, the news agency on Saturday quoted China's Meteorological Administration as saying.

Temperatures recorded over the country since November have averaged minus 3.8 degrees Celsius (25 degrees Fahrenheit), while northeast China saw average temperatures of minus 15.3 degrees Celsius, its coldest winter for 43 years.

Plunging temperatures trapped around 1,000 ships in sea ice off eastern China's Shandong province this week, Xinhua reported, while snowfall delayed more than 140 flights in Beijing last month, the China Daily said.

An annual Ice and Snow Festival in the northeastern city of Harbin, famous for its enormous ice-sculptures, is scheduled to open on Saturday, as temperatures in the city fall below minus 24 degrees Celsius.

Temperatures in northern China are expected to pick up next week, although parts of south China will continue to experience snow, Xinhua reported.

What does the International Space Station sound like?



Can you hear me, Major Tom? Hadfield rocks out in the ISS cupola.



(Credit:
Canadian Space Agency)



If you're heading to the International Space Station, try to bunk in the Japanese section. It's as quiet as a Zen temple.


Canadian astronaut Chris Hadfield recently went aboard the ISS and has been recording what it sounds like. It's not quite the elegant "2001: A Space Odyssey" experience you might expect. It's more like a noisy tin can.


After recording last week the ambient sounds of the U.S. lab, with its noisy air pumps and fans, Hadfield managed to get samples of what the ISS toilet sounds like, as well as the relative serenity of the Japanese Experiment Module (aka Kibo).




Check them out below, or listen to a larger selection here.




Hadfield has been very busy taking some amazing photos of Earth, updating his Facebook status, and performing the odd astro-duty like running experiments.


A couple of days ago, he received a message on Twitter from William Shatner, who asked whether he was tweeting from space.


"Yes, Standard Orbit, Captain," Hadfield replied. "And we're detecting signs of life on the surface."


That gave Trekkies, including yours truly, tribble-like quivers of delight.


Inspired by the view from the ISS cupola, the mustachioed commander of Expedition 35 grabbed a guitar and recorded an original tune, a first for the station. He titled it "Jewel in the Night" and uploaded it to YouTube. Give it a listen below.


It doesn't have the makings of a space classic like "Rocket Man" (the Shat version, of course), but it's heartfelt and quite a bit better than Spock's "Maiden Wine."


And likely a welcome relief for crewmates from all that high-tech racket.

Debt Limit Negotiating Tactic? No Negotiating


ap obama ac 130102 wblog In Fiscal Wars No Negotiation Is a Negotiating Tactic

Analysis


New for 2013: In the Washington, D.C. fiscal wars we’ve gone from everything must be on the table to politicians declaring they won’t debate.


The fiscal cliff deal either averted disaster or compounded the problem, depending on who you ask. It certainly created new mini-cliffs in a few months as Congress and the president square off on the debt ceiling, spending cuts and government funding. But it also made sure the vast majority of Americans won’t see as big a tax hike as they might have.


President Obama was pretty clear late on New Year’s night as he reacted to Congress’s passage of a bill to take a turn away from the fiscal cliff. He won’t negotiate with Republicans about the debt ceiling.


“Now, one last point I want to make,” said the president, before wrapping up and hopping on Air Force One for a redeye to Hawaii. “While I will negotiate over many things, I will not have another debate with this Congress over whether or not they should pay the bills that they’ve already racked up through the laws that they passed.”


(Read more here about the Fiscal Cliff)


That’s pretty clear. No debt ceiling negotiation. Then he added for emphasis: ”Let me repeat: We can’t not pay bills that we’ve already incurred. If Congress refuses to give the United States government the ability to pay these bills on time, the consequences for the entire global economy would be catastrophic — far worse than the impact of a fiscal cliff.”


But in Washington, saying you won’t do something these days has almost become like an opening bid. At least, that’s how Republicans are treating the president’s line in the sand.


“The president may not want to have a fight about government spending over the next few months, but it’s the fight he is going to have because it’s a debate the country needs,” wrote Senate Minority Leader Mitch McConnell, the Kentucky Republican, in an op-Ed on Yahoo! News about 36 hours later. “For the sake of our future, the president must show up to this debate early and convince his party to do something that neither he nor they have been willing to do until now.”


“We simply cannot increase the nation’s borrowing limit without committing to long overdue reforms to spending programs that are the very cause of our debt,” McConnell said.


The national debt is soon set to reach $16.4 trillion. That’s not a problem that can be solved with one bill or budget. And the two sides will have to figure out some sort of way to talk about entitlement/social safety net reform – meaning things like Medicare, Medicaid, and Social Security – in addition to cutting spending and, most importantly, hope for an improving economy, to deal with those deficits.


House Speaker John Boehner, who has several times now failed to reach a big, broad fiscal deal with President Obama, told colleagues, according to The Hill newspaper, that he’s done with secret White House negotiations. He wants to stick with the constitutional way of doing things, with hearings and bills that are debated on Capitol Hill rather than hatched by the vice president and Senate Republicans.


Okay. Obama won’t negotiate on the debt ceiling. McConnell won’t not negotiate on the debt ceiling. Boehner doesn’t to do things by the book.


But McConnell won’t negotiate on taxes any more.


“Predictably,” McConnell had written earlier in his post, “the president is already claiming that his tax hike on the ‘rich’ isn’t enough. I have news for him: the moment that he and virtually every elected Democrat in Washington signed off on the terms of the current arrangement, it was the last word on taxes. That debate is over.”


It’s a new chapter in the ongoing fiscal saga in Washington. Back when the two sides were talking about a grand bargain or a big deal – some sort of all-inclusive reform that would right the listing deficit with one flip of the rudder – the popular trope was that “everything must be on the table.” That’s basically how Obama put it back in the summer of 2011 when he and Boehner failed to reach a grand bargain. He wanted higher taxes – they were calling them revenues back then. More recently, after Obama won the election and when he and Boehner were trying to hammer out another grand bargain to avert the fiscal cliff, Boehner wanted entitlements on the table. That means he wanted to find ways to curb future spending.


Both sides are declaring they won’t debate certain points, but this far – a full two months – before the mini-cliffs start, those are easier declarations to make than they will be when the government is in danger of defaulting or shutting down.


Even though they’re trying to take elements off the table, both men hope that coming negotiations can be a little more cordial and a little less down-to-the wire.


“Over the next two months they need to deliver the same kind of bipartisan resolution to the spending problem we have now achieved on revenue — before the 11th hour,” wrote McConnell.


“The one thing that I think, hopefully, in the New Year we’ll focus on is seeing if we can put a package like this together with a little bit less drama, a little less brinksmanship, not scare the heck out of folks quite as much,” said Obama.


That’ll be tough if neither side will talk about what the other side wants to talk about.

Spare elephants or I'm off to Russia: Bardot






PARIS: French cinema legend Brigitte Bardot on Friday threatened to follow Gerard Depardieu to Russia unless two elephants under threat of being put down are granted a reprieve.

In a surreal twist to the saga over Depardieu's move into tax exile, the veteran animal rights campaigner said she would emulate his request for Russian nationality unless authorities intervened to save Baby and Nepal.

The two elephants face being put down because they have been diagnosed with tuberculosis and have been deemed a threat to the health of other animals and visitors to the Tete d'Or zoo in Lyon.

City authorities ordered the elephants to be put down last month but a petition organised by their original owner, circus master Gilbert Edelstein, resulted in them being granted a temporary reprieve over Christmas.

Bardot said in a statement she would be leaving France if the reprieve was not made permanent.

"If the powers that be have the cowardice and the shamelessness to kill Baby and Nepal... I have decided to take Russian nationality and quit this country that is nothing more an animal cemetery," Bardot said.

Bardot, 77, has been a high-profile supporter of Depardieu in his spat with the French government over his decision to take up residence in neighbouring Belgium for tax reasons.

She said last month that her fellow actor, who was branded "pathetic" by Prime Minister Jean-Marc Ayrault, had been the "victim of extremely unfair persecution".

EU: FTC decision on Google won't affect our case



Google's headquarters in Mountain View, Calif.

James Martin/CNET)



Google may be free and clear in the U.S. over its search practices, but the European Union still has a thing or two to say.


The European Commission, which is the executive body of the European Union, told Reuters that the FTC settlement with the Internet search giant wouldn't affect own decision-making process, although it has taken note of it.



The U.S. Federal Trade Commission yesterday announced a settlement with Google, allowing competitors unhappy with how its search results are displayed to opt out and forcing the company to make some changes to its search practices to appease regulators.


Some, however, believe Google got off lightly -- it avoided having to pay any fines. Separately, Google was told to stop blocking the use of crucial standards-based patents that it and unit Motorola Mobility own.


The European Commission has spent the past two years investigating Google after competitors such as Microsoft complained that Google adjusted search results to bring up its products and Web sites first. Google is expected to attempt to address the concerns of European regulators this month.


Google could face fines up to $4 billion if it fails to reach an agreement with European regulators.

Pictures We Love: Best of 2012

Photograph by Mindy Schauer, Orange County Register/AP

Powder-splattered, and powder-splattering, runners cross the finish line of The Color Run 5K in Irvine, California, on April 22. Each kilometer (0.6 mile) of the event features a color-pelting station dedicated to a single hue, culminating in the Pollock-esque riot at kilometer 5.

The "magical color dust" is completely safe, organizers say, though they admit it's "surprisingly high in calories and leaves a chalky aftertaste."

Chelsea Clinton Raises Profile During Mom's Illness













While Hillary Clinton was in the hospital it was daughter Chelsea -- not the secretary of state or the former president Bill Clinton -- who spoke for the family.


She, along with the State Department, doled out what little information the family wanted to share in a series of tweets and when her mother was released from the hospital, it was Chelsea who delivered the thanks on behalf of her parents, tweeting her gratitude to the doctors as well as those who kept her mother in their thoughts while she recovered from a blood clot.


When Hillary Clinton leaves office, possibly at the end of this month, it will be the first time since 1982 that a Clinton will not be holding a public office.


The watch will be on whether Hillary Clinton makes another run for the White House in 2016, but almost inevitably people will also be watching to see if Chelsea Clinton decides to run for office, too.


"Americans always look for dynasties: Bush, Kennedy, Cuomo, Clinton … it's some kind of continuity. There will always be pressure on her to run for public office," said Hank Sheinkopf, a Democratic political strategist in New York.


"She's learning from the two best politicians in recent American history and she understands when to hold them and when to fold them," Sheinkopf said.


That sense of dynasty could also present a significant hurdle.

"She's got to A, demonstrate that she has the charisma of her father, or B, demonstrate that she has the policy chops of her mother. And I think like most people she is somewhere in between," a former Hillary Clinton aide from her 2008 campaign said. "People are judging her through each of her parents and it's an impossible standard."


Chelsea Clinton, 32, has inched towards a possible political career in recent statements and has become more politically active.


In an interview with Vogue published in August she was more open to it than she has been in the past, telling the magazine, "Before my mom's (presidential) campaign I would have said no," but "now I don't know."


"I believe that engaging in the political process is part of being a good person. And I certainly believe that part of helping to build a better world is ensuring that we have political leaders who are committed to that premise. So if there were to be a point where it was something I felt called to do and I didn't think there was someone who was sufficiently committed to building a healthier, more just, more equitable, more productive world? Then that would be a question I'd have to ask and answer."


Clinton also spoke of a change in her private to public life:


"Historically I deliberately tried to lead a private life in the public eye," she told the magazine. "And now I am trying to lead a purposefully public life."


Besides her work as a special correspondent with NBC, Chelsea Clinton has taken on high profile roles with her father's Clinton Global Initiative. She sits on several corporate boards and has both moderated and sat on panels discussing both women in politics and childhood obesity, among other issues.


She has also worked toward making same-sex marriage legal in New York last year, as well as gay marriage referendums in Maine, Maryland, Wisconsin and Washington state, all of which were successful in November. She has also been active in superstorm Sandy recovery, most notably delivering aid to the devastated Rockaways with her father.
