Twitter has bought Crashlytics, a startup whose crash reporting tool has been incorporated into a wide variety of iOS apps including Vine, Yelp, Kayak, TaskRabbit, and Waze.


In a blog post today, Crashlytics co-founders Jeff Seibert and Wayne Chang announced that the company is "joining the flock," the term often used when people or companies are hired or acquired by Twitter:


We started Crashlytics a little over a year ago to address a huge hole in mobile app development. With hundreds of millions of devices in use around the world, it was impossible for developers to fully test every edge-case and catch every bug before release. Even worse, when problems did crop up, it was often difficult and complicated to find the root cause. App developers were stuck with little insight into what happened and forced to rely on vague end-user feedback to diagnose problems.


We built Crashlytics to deliver the world's most powerful and lightest-weight crash reporting solution. With us, developers gain instant visibility into the precise line of code that caused a crash, enabling them to more easily fix issues. Since our iOS launch, we've had the privilege of working with thousands of incredible app developers, from those building independent passion-projects to many of the top iOS apps available today.



Twitter didn't immediately respond to a request for comment, although the company did tweet news of the acquisition.

Urban Heat May Warm Faraway Places


The massive amounts of heat produced by cities may be heating up rural areas 1,000 miles (1,600 kilometers) away, atmospheric researchers have found in a new modeling study.

Scientists have long invoked the "urban island heat effect" to explain why cities are generally hotter than suburban and rural areas. More people, as well as more cars, houses, and paved surfaces, turn energy into heat, which is radiated into the atmosphere.

But new modeling research from the Scripps Institution of Oceanography at the University of California, San Diego, suggests that cities in the Northern Hemisphere can also increase the heat of faraway rural places up to 1.8ºF (1°C)—a substantial aggregate increase.

The reason comes down to global air flow.

Heat produced by cars and people travels about 2,500 feet (4,023 kilometers) into the atmosphere, where it disturbs part of the jet stream that continually circulates a belt of cool air around the top of the planet. When hot air intercepts the jet stream, it pushes the belt upward, allowing warmer air from the Equator to come farther north, warming parts of northern Europe and North America that normally would have been cooler.

Over the Northern Hemisphere, 86 major metropolitan areas cover only 1.27 percent of the Earth's surface. But those areas consume 6.7 terawatts of energy annually—representing 42 percent of annual global consumption.

Those cities' influence on global climate is therefore magnified, according to the study, published Sunday in the journal Nature Climate Change.

Until now, climate researchers have mostly pointed to greenhouse gasses as the sole cause of climate change. But the planet has been warming in some areas faster than models have predicted.

The impacts of urban heat produced by energy consumption may account for some of that extra warming, said Guang Zhang, a meteorologist at Scripps who conducted the study: "Essentially, we are now able to account for a missing part of the warming."

Zhang found that the areas most significantly impacted by this urban heat effect were Siberia and northern Canada, which can see temperatures rise 1.4º to 1.8°F (0.8° to 1°C) due to urban heat in faraway cities like New York or San Francisco.

Further south, areas like Minnesota and Michigan might see a 0.5°F (0.3°C) increase. The modeling was conducted with data from the National Center for Atmospheric Research, a leading source of global climate data.

While it's true that the Earth's aggregate climate affects every spot on the planet, the impacts of city heat were most pronounced in the Northern Hemisphere, where nearly 90 percent of the global population lives. And the most dramatic cool usually comes in the fall, the researchers said, for reasons that can't yet be fully explained.

Immigration Plan Includes Path to Citizenship












A bipartisan group of senators on Monday formally unveiled their proposal to drastically overhaul the nation's immigration system, with the hope of passing a bill out of the Senate by late spring or early summer.


"We believe this will be the year Congress finally gets it done," Sen. Chuck Schumer (D-N.Y.) one of the members of the so-called "Gang of Eight" said during a press conference on Capitol Hill.


See Also: Transcript: Framework for Immigration Reform


Five of the eight members of the group -- Schumer, Bob Menendez (D-N.J.), Dick Durbin (D-Ill.), Marco Rubio (R-Fla.), and John McCain (R-Ariz.) -- appeared at the press conference intended to outline their immigration proposal. The proposal would provide a path to citizenship for many of the nation's 11 million undocumented immigrants while upping border security and cracking down on businesses that hire workers who are not legally present in the U.S.


Sens. Jeff Flake (R-Ariz.), Lindsey Graham (R-S.C.), and Michael Bennet (D-Colo.) were the members not in attendance.


The senators all expressed optimism that their legislation could pass both the House and the Senate. Schumer added that he hopes to have an actual piece of legislation done by the end of March, and then have the Senate act on it right away.

But while some conservatives have signaled support for the Senate framework, many others have resisted any plan that could grant a pathway to citizenship to undocumented immigrants, saying it amounts to amnesty for people who broke the law.


The Senate's plan does not grant undocumented immigrants automatic "amnesty," rather it requires them to go through an arduous process that includes undergoing a background check, paying fines, back taxes and learning English and American civics over the course of a number of years. The new law would grant eligible undocumented immigrants permission to live and work in the U.S. legally, but would not confer permanent legal status, or a green card, until the border is deemed to be secure. Young people brought into the U.S. illegally as minors and some agricultural workers would face an easier path to citizenship.


"We will never put these people on a path to citizenship until we have secured the border," Schumer said.


McCain, who helped lead the last effort on a comprehensive immigration bill in 2007 said, "We have been too content for too long to allow individuals to mow our lawns, grow our food, clean our homes, and even watch our children while not affording them any of the benefits that make our country so great."


Senators in both political parties suggested that the reason that some Republicans have had a change of heart was because of the results of last November's election, when seven in 10 Latino voters backed President Barack Obama over Republican Mitt Romney.


"The politics on this issue have been turned upside down," Schumer said. "For the first time ever, there is more political risk in opposing immigration reform, than in supporting it."


Perhaps more than anyone on the stage, McCain understands this. While he backed comprehensive immigration reform five years ago, he backed away from it during his 2010 run for Senate, just as his home state was considering the SB 1070 crackdown law on undocumented immigrants.


McCain went so far as to say that the current plan is a "testimonial" to bill he worked on with Sen. Ted Kennedy (D-Mass.), the late liberal icon, in 2007.


Another member of the group, Marco Rubio, had not always voiced support for a pathway to citizenship for undocumented immigrants during his Senate career. But on Monday, he said that Congress needs to "address the reality" of the massive undocumented population in the U.S.

DNA privacy: don't flatter yourself






















The secrets contained in our individual genomes are less valuable than we like to believe
















IMAGINE donating your DNA to a project aimed at discovering links between genes and diseases. You consent to your genome sequence being released anonymously into the public domain, though you are warned there is a remote possibility that it might one day be possible to link it back to you.











A few years later, that remote possibility comes to pass. How should you feel? This is no longer a hypothetical scenario. About 50 people who participated in a project called 1000 Genomes have been traced (see "Matching names to genes: the end of genetic privacy?").













The researchers' intentions were honourable. They have not revealed these identities, and the original data has been adjusted to make a repeat using the same technique impossible. All they wanted to do was expose privacy issues.












Consider them exposed. It is clear that genomics has entered a new phase, similar to that which social media went through a few years ago, when concerns were raised about people giving away too much personal information.












What happens when the same applies to our DNA? Having your genome open to public scrutiny obviously raises privacy issues. Employers and insurers may be interested. Embarrassing family secrets may be exposed.












But overall, personal genetic information is probably no more revealing than other sorts. In fact there are reasons to believe that it is less so: would an insurance company really go to the trouble of decoding a genome to discover a slightly elevated risk of cancer or Alzheimer's disease?












The available evidence suggests not. In 2006, Harvard University set out to sequence the genomes of 100,000 volunteers and make them publicly available, along with personal information such as names and medical records. One of the goals was to see what happens when such data is open to all. The answer seems to be "not a lot". So far this Personal Genome Project has published 148 people's full genomes. Not one volunteer has reported a privacy issue.












This is not a reason for complacency, but it suggests that our genomic secrets are less interesting to other people than we might like to believe.

Fired workers protest at South Korean embassy in Iran






TEHRAN: Around 1,000 workers laid off by Iran's Entekhab group demonstrated outside the South Korean embassy in Tehran on Sunday after an acquisition deal for Daewoo Electronics fell through because of sanctions.

Entekhab had to let them go when it shut down a manufacturing line, the company said.

Three months ago, employees demonstrated at the embassy in the hope that Seoul would intervene to refund a downpayment of $70 million (53 million euros) Entekhab paid in 2011 to Daewoo.

In November 2010, the privately run Entekhab Industrial Group signed a contract sealing its acquisition of Daewoo for $518 million (397 million euros), the manufacturer maintains.

"Today, around 1,200 laid off workers from our company gathered again in front of the South Korean embassy after we did not get the money back," Entekhab's media spokesman Eshsan Fadaee said.

Daewoo Electronics, a former subsidiary of the now-defunct Daewoo Group, has been under a debt rescheduling programme since 1999 when its parent company collapsed.

Entekhab's deal to acquire Daewoo Electronics came unstuck in September 2010 when Seoul, reportedly under pressure from Washington, slapped sanctions on the Islamic republic over its controversial nuclear programme.

Entekhab, located in the central province of Isfahan, produces domestic appliances including refrigerators, washing machines and televisions under the brand names Snowa and Haier.

Under the punitive measures, South Korea has suspended the operations of Iran's Bank Mellat.

The United Nations, European Union, United States, and several other countries have imposed sanctions on Iran for its refusal to halt uranium enrichment, which world powers suspect masks an atomic weapons drive despite Tehran's denials.

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.




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.


CNET has contacted Twitter for comment and will update this report when we learn more.


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 also contacted Apple for comment and will update this report when we learn more.

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

Photograph by Art Wolfe, Getty Images

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 Roussef 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," Roussef 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.

Sailing: Olympic sailing champion visits Singapore






SINGAPORE: Xu Lijia, the 25 year old who became the first Chinese to win a gold medal in the dinghy class after finishing first in the laser radial class at the 2012 London Olympics, is in town.

The Chinese athlete shared her experiences with local sailors at a talk, which attracted 500 participants. The talk also saw the launch of the Character Development Through Sailing programme.

The Shanghai native, who won bronze in the same class at the 2008 Olympics in Beijing, said that it was not just about winning, but also enjoying the journey.

She had to beat many odds including injuries, physical limitations and the lack of a proper support structure for the sport in China.

"It is about promotion, promoting this sport not only in Singapore, China but... in whole of Asia. I hope that Asia can become stronger and stronger and (compete) with the European countries," she said.
