Pornographic video clips already showing up on Twitter's Vine

Less than a week after Twitter unveiled Vine, the video-sharing app apparently has developed a porn problem.

Released Thursday, the app for iPhone and
iPod Touch lets anyone create and share six-second clips, but it also has become a popular venue for male genitalia and pornographic movies taped off TVs and laptops. As first pointed out last night by The New York Times' Nick Bilton, searches for #porn, #sex, and other associated tags brings up a handful of videos featuring male exhibitionism and other activity.

While Vine's terms of service don't expressly forbid sexually explicit content, Twitter does encourage users to use good judgment when posting content:

You are responsible for your use of the Services, for any Content you post to the Services, and for any consequences thereof. The Content you submit, post, or display will be able to be viewed by other users of the Services and through third party services and websites. You should only provide Content that you are comfortable sharing with others under these Terms.

However, Vine users can flag videos they find offensive. If clips receive enough complaints, Twitter will add a warning still to the beginning of the video that users have to bypass to see the clip, a Twitter representative told CNET.

"Uploaded videos that are reported and determined to violate our guidelines will be removed from the site, and the user that posted the video may be terminated," the representative said in a statement.

Long an advocate for freedom of expression, Twitter has been reluctant to censor tweets. A year ago, the microblogging site announced it would be willing to remove tweets on a country-by-country basis when there are local restrictions against specific content in the tweets.

While the NSFW content might not violate Twitter's TOS, Apple's App Store guidelines state that "apps containing pornographic material, defined by Webster's Dictionary as 'explicit descriptions or displays of sexual organs or activities intended to stimulate erotic rather than aesthetic or emotional feelings,' will be rejected."

Apple recently removed an app called 500px, presumably because of its photo-sharing capabilities, which might allow users to search for and find naked bodies. CNET has contacted Apple for comment and will update this report when we learn more.

Pictures: The Story Behind Sun Dogs, Penitent Ice, and More

If you want the beauty of winter without having to brave the bone-chilling temperatures blasting much of the United States this week, snuggle into a soft blanket, grab a warm beverage, and curl up with some of these natural frozen wonders.

Nieve penitente, or penitent snow, are collections of spires that resemble robed monks—or penitents. They are flattened columns of snow wider at the base than at the tip and can range in height from 3 to 20 feet (1 to 6 meters). The picture above shows the phenomenon in central Chile. (See pictures of the patterns in snow and ice.)

Nieve penitente tend to form in shallow valleys where the snow is deep and the sun doesn't shine at too steep an angle, said Kenneth Libbrecht, a physicist at the California Institute of Technology in Pasadena who studies ice crystal formation.

As the snow melts, dirt gets mixed in with the runoff and collects in little pools here and there, he said. Since the dirt is darker in color than the surrounding snow, the dirty areas melt faster "and you end up digging these pits," explained Libbrecht.

"They tend to form at high altitude," he said. But other than that, no one really knows the exact conditions that are needed to form penitent snow.

"They're fairly strong," Libbrecht said. "People have found [the spires] difficult to hike through."

Brazil Nightclub Fire: 232 Dead, Hundreds Injured

Flames raced through a crowded nightclub in southern Brazil early Sunday, killing more than 230 people as panicked partygoers gasped for breath in the smoke-filled air, stampeding toward a single exit partially blocked by those already dead. It appeared to be the world's deadliest nightclub fire in more than a decade.

Witnesses said a flare or firework lit by band members started the blaze in Santa Maria, a university city of about 225,000 people, though officials said the cause was still under investigation.

Television images showed smoke pouring out of the Kiss nightclub as shirtless young men who had attended a university party joined firefighters using axes and sledgehammers to pound at windows and walls to free those trapped inside.

Guido Pedroso Melo, commander of the city's fire department, told the O Globo newspaper that firefighters had a hard time getting inside the club because "there was a barrier of bodies blocking the entrance."

Teenagers sprinted from the scene desperately seeking help. Others carried injured and burned friends away in their arms.

"There was so much smoke and fire, it was complete panic, and it took a long time for people to get out, there were so many dead," survivor Luana Santos Silva told the Globo TV network.

The fire spread so fast inside the packed club that firefighters and ambulances could do little to stop it, Silva said.

Another survivor, Michele Pereira, told the Folha de S. Paulo newspaper that she was near the stage when members of the band lit flares that started the conflagration.

"The band that was onstage began to use flares and, suddenly, they stopped the show and pointed them upward," she said. "At that point, the ceiling caught fire. It was really weak, but in a matter of seconds it spread."

Guitarist Rodrigo Martins told Radio Gaucha that the band, Gurizada Fandangueira, started playing at 2:15 a.m. "and we had played around five songs when I looked up and noticed the roof was burning"

"It might have happened because of the Sputnik, the machine we use to create a luminous effect with sparks. It's harmless, we never had any trouble with it.

"When the fire started, a guard passed us a fire extinguisher, the singer tried to use it but it wasn't working"

He confirmed that accordion player Danilo Jacques, 28, died, while the five other members made it out safely.

Police Maj. Cleberson Braida Bastianello said by telephone that the toll had risen to 233 with the death of a hospitalized victim — he said earlier that the death toll was likely made worse because the nightclub appeared to have just one exit through which patrons could exit.

Officials counted 232 bodies that had been brought for identification to a gymnasium in Santa Maria, which is located at the southern tip of Brazil, near the borders with Argentina and Uruguay.

Federal Health Minister Alexandre Padhilha told a news conference that most of the 117 people treated in hospitals had been poisoned by gases they breathed during the fire. Only a few suffered serious burns, he said.

Brazil President Dilma Rousseff arrived to visit the injured after cutting short her trip to a Latin American-European summit in Chile.

"It is a tragedy for all of us," Rousseff said.

Most of the dead apparently were asphyxiated, according to Dr. Paulo Afonso Beltrame, a professor at the medical school of the Federal University of Santa Maria who went to the city's Caridade Hospital to help victims.

Get cirrus in the fight against climate change

FEATHERY cirrus clouds are beautiful, but when it comes to climate change, they are the enemy. Found at high-altitude and made of small ice crystals, they trap heat - so more cirrus means a warmer world. Now it seems that, by destroying cirrus, we could reverse all the warming Earth has experienced so far.

In 2009, David Mitchell of the Desert Research Institute in Reno, Nevada, proposed a radical way to stop climate change: get rid of some cirrus. Now Trude Storelvmo of Yale University and colleagues have used a climate model to test the idea.

Storelvmo added powdered bismuth triiodide into the model's troposphere, the layer of the atmosphere in which these clouds form. Ice crystals grew around these particles and expanded, eventually falling out of the sky, reducing cirrus coverage. Without the particles, the ice crystals remained small and stayed up high for longer.

The technique, done on a global scale, created a powerful cooling effect, enough to counteract the 0.8 °C of warming caused by all the greenhouse gases released by humans (Geophysical Research Letters, DOI: 10.1002/grl.50122).

But too much bismuth triiodide made the ice crystals shrink, so cirrus clouds lasted longer. "If you get the concentrations wrong, you could get the opposite of what you want," says Storelvmo. And, like other schemes for geoengineering, side effects are likely - changes in the jet stream, say.

Different model assumptions give different "safe" amounts of bismuth triiodide, says Tim Lenton of the University of Exeter, UK. "Do we really know the system well enough to be confident of being in the safe zone?" he asks. "You wouldn't want to touch this until you knew."

Mitchell says seeding would take 140 tonnes of bismuth triiodide every year, which by itself would cost $19 million.

Germany has 'everlasting responsibility' for Nazi crimes: Merkel

 

BERLIN: Germany has "an everlasting responsibility" for the crimes committed by the Nazis, Chancellor Angela Merkel said Saturday, just days ahead of the 80th anniversary of Adolf Hitler's takeover of power.

"Naturally, we have an everlasting responsibility for the crimes of national-socialism, for the victims of World War II, and above all, for the Holocaust," Merkel said in a podcast on her website.

Her remarks came as the world prepares to mark Holocaust Memorial Day on January 27, the date in 1945 when the Soviet army liberated the Auschwitz concentration camp in then occupied Poland.

In another significant date, Wednesday will mark eight decades since Hitler was appointed chancellor on January 30, 1933 by then president Paul von Hindenburg.

"We must clearly say, generation after generation, and say it again: with courage, civil courage, each individual can help ensure that racism and anti-Semitism have no chance," Merkel added.

"We're facing our history, we're not hiding anything, we're not repressing anything. We must confront this to make sure we are a good and trustworthy partner in the future, as we already are today, thankfully," she said.

In Swartz protest, Anon hacks U.S. site, threatens leaks

In response to the death of tech activist Aaron Swartz, hacktivist collective Anonymous hacked a U.S. government Web site related to the justice system and posted a screed saying it would begin leaking a cache of government documents if the justice system is not reformed.

The group hacked the Web site for the United States Sentencing Commission late Friday, posting a message about what it's calling "Operation Last Resort," along with a set of downloadable encrypted files it said contain sensitive information. The sentencing commission is the caretaker of the guidelines for sentencing in U.S. federal courts.

"Two weeks ago today, a line was crossed," the group's statement reads. "Two weeks ago today, Aaron Swartz was killed. Killed because he faced an impossible choice. Killed because he was forced into playing a game he could not win -- a twisted and distorted perversion of justice -- a game where the only winning move was not to play."

The recent suicide of Swartz, a proponent of freely accessible information, has been blamed by some on what they say were outrageously aggressive efforts on the part of the U.S. Attorney in Massachusetts to punish Swartz for his alleged theft of millions of articles from a database of academic journals. The 26-year-old Swartz, who struggled with bouts of depression, had been charged with 13 felonies and threatened with decades in prison and fines exceeding $1 million. U.S. Attorney Carmin Ortiz says Swartz' lawyers were also offered a plea bargain in which he'd plead guilty and serve perhaps 6 months.

Anonymous encouraged its followers to download the files on the hacked site, a set of nine downloads named after the U.S. Supreme Court's nine justices and collectively referred to by the hacking collective as a "warhead."

"Warhead-US-DOJ-LEA-2013.AEE256 is primed and armed. It has been quietly distributed to numerous mirrors over the last few days and is available for download from this website now. We encourage all Anonymous to syndicate this file as widely as possible."

The group wouldn't specify what, exactly, is in the files, saying only that "the contents are various and we won't ruin the speculation by revealing them. Suffice it to say, everyone has secrets, and some things are not meant to be public. At a regular interval commencing today, we will choose one media outlet and supply them with heavily redacted partial contents of the file."

The contents of the encrypted files can apparently be accessed only with a decryption key, and Anonymous said it didn't necessarily want to provide that key to its followers -- it mentioned "collateral damage" as a result of any leaks and said "It is our hope that this warhead need never be detonated." But the group said the U.S. government must begin acting on reforms to the justice system suggested by the system's critics, and in spelling out its demands more specifically, it mentioned plea bargaining and suggested the overhaul of legislation such as the mid-1980s antihacking law entitled the Computer Fraud and Abuse Act.

...in order for there to be a peaceful resolution to this crisis, certain things need to happen. There must be reform of outdated and poorly-envisioned legislation, written to be so broadly applied as to make a felony crime out of violation of terms of service, creating in effect vast swathes of crimes, and allowing for selective punishment. There must be reform of mandatory minimum sentencing. There must be a return to proportionality of punishment with respect to actual harm caused, and consideration of motive and mens rea [criminal intent]. The inalienable right to a presumption of innocence and the recourse to trial and possibility of exoneration must be returned to its sacred status, and not gambled away by pre-trial bargaining in the face of overwhelming sentences, unaffordable justice, and disfavourable odds. Laws must be upheld unselectively, and not used as a weapon of government to make examples of those it deems threatening to its power.

The group said it had acquired the files by compromising various government Web sites and installing "leakware," which it has since removed to cover its tracks.

Here's the video Anon posted on the commission's site. A Google cache of the hacked home page, which includes the text version of the screed, can be seen here.

Newtown Families March for Gun Control in DC

Jan 26, 2013 4:59pm

(YURI GRIPAS/AFP/Getty Images)

WASHINGTON, D.C. — Near-freezing temperatures didn’t stop several thousand gun-control activists from bearing their pickets today, carrying signs emblazoned with “Ban Assault Weapons Now” and the names of gun violence victims in a demonstration organized as a response to the mass shooting in Newtown, Conn. last month.

Walking in silence, the demonstrators trudged between Capitol Hill and the Washington Monument over a thin layer of melting snow. They were joined by politicians and some families of the Newtown victims.

March organizer Shannon Watts said the event was for the “families who lost the lights of their lives in Newtown, daughters and sons, wives and mothers, grandchildren, sisters and brothers gone in an unfathomable instant.”

“Let’s stand together and use our voices, use our votes to let legislators know that we won’t stand down until they enact common sense gun control laws that will keep our children out of the line of fire,” she told demonstrators.

Watts founded One Million Moms for Gun Control after the killing of 20 first graders and six adults at the Sandy Hook Elementary School in Newtown in December. In a profile with the New York Times, Watts said her 12-year-old son had suffered panic attacks after learning of last summer’s Aurora, Colo., theater shooting, leaving her at an impasse over how to talk to him about the latest tragedy.

Also among the speakers was a survivor of the 2007 Virginia Tech massacre, Collin Goddard.

“We need to challenge any politician who thinks it’s easier to ask an elementary school teacher to stand up to a gunman with an AR-15 than it is to ask them to stand up to a gun lobbyist with a checkbook,” he said.

The demonstration comes amid a push by progressive lawmakers to enact stricter gun control measures as a response to the trend of recent mass killings, although any hypothetical bill would likely face strong opposition in Congress.

Rep. Chris Van Hollen, D-Md., was among the demonstrators today.

“The idea that people need high-capacity magazines that can fire 30, 50, 100 rounds has no place in a civilized society,” he said. “Between the time we’re gathered here right now and this time of day tomorrow, across America, 282 Americans will have been shot.”

The congressman was quoting statistics compiled by the Brady Campaign to Stop Gun Violence.

INFOGRAPHIC: Guns by the Numbers

Last week President Obama proposed a sweeping overhaul of federal measures regulating gun ownership, including a universal background check system for sales, banning assault weapons,  and curbing the amount of ammunition available in weapon clips.

An ABC News/Washington Post poll released Thursday found 53 percent of Americans viewed Obama’s gun control plan favorably, 41 percent unfavorably. The division was visible today, as a handful of gun-rights advocates also turned out on the National Mall to protest what they believe would be infringements on their Second Amendment liberties.

ABC’s Joanne Fuchs contributed to this report.

Procter & Gamble raises outlook on soaring profit

NEW YORK: Procter & Gamble reported Friday profit more than doubled in the fiscal second quarter from a year ago, beating market expectations, and raised its forecasts for the year.

The US consumer goods giant said profit jumped 140 per cent due to strong productivity gains and the effects of cost-saving efforts.

Net income rose to US$4.1 billion, or US$1.39 per share, compared with the year-ago figure of US$1.7 billion, or 57 cents per share, the company said.

The results were well above analyst expectations.

Core earnings per share, which strips out special items and other items not related to sustainable earnings, were US$1.22, sharply more than the US$1.11 estimated.

Revenues came in at US$22.18 billion, above the US$21.91 billion forecast by analysts.

Shares in the Dow member were up 3.5 per cent at US$72.87 in late-afternoon trade in New York.

"Global market share trends improved as we continued to implement our growth strategy and made very good progress against our productivity and cost-savings goals," said chief executive Bob McDonald.

"Our strong first-half results have enabled us to raise our sales, earnings and share repurchase outlook for the fiscal year."

Procter & Gamble, which manufactures Pampers diapers, Head and Shoulders shampoo and other household products, said its growth was broad-based and that all five of its business segments grew organic sales by at least two per cent.

The biggest growth came in the company's baby care and family care segment with 5 per cent.

Procter & Gamble raised its full-year 2013 core earnings guidance to US$3.97-US$4.07 from the previous range of US$3.80-US$4.00.

In a conference call with analysts, P&G executives said the company had completed most of a previously announced downsizing to trim costs. In February, the company announced it was cutting 5,700 non-manufacturing posts. McDonald said that 5,500 of the job cuts had already been implemented.

At the end of October, the Cincinatti, Ohio-based company had a total of 126,000 employees. The group did not give figures for the end of December.

Procter & Gamble also raised its forecast of 2013 share repurchases to a range of US$5-6 billion, up from the previous range of US$4-6 billion.
