Netflix streaming service back online after outage

Those hoping to spend the holiday watching streaming video from Netflix can now get back in front of their TVs, tablets and PCs after a Christmas Eve outage.
A Netflix Inc. spokesman said by email Tuesday morning that the service has been fully restored.
The outage affected customers in the Americas starting around 12:30 p.m. PST on Monday. The company, which is based in Los Gatos, Calif., blames problems with Amazon Web Services, and says it is investigating further.
Amazon Web Services provides companies with online storage and computing. It is separate from Seattle-based Amazon.com Inc.'s better-known shopping website.
Amazon says that problems with its service have also now been fixed.

Home prices rose in ninth straight month: S&P

 Single-family home prices rose in October for nine months in a row, reinforcing the view the domestic real estate market is improving and should bolster the economy in 2013, a closely watched survey showed on Wednesday.
The S&P/Case Shiller composite index of 20 metropolitan areas gained 0.7 percent in October on a seasonally adjusted basis, stronger than the 0.5 percent rise forecast by economists polled by Reuters.
"Looking over this report, and considering other data on housing starts and sales, it is clear that the housing recovery is gathering strength," David Blitzer, chairman of the index committee at Standard & Poor's, said in a statement.
While record low mortgage rates and modest job growth should keep the housing recovery on track, analysts cautioned home prices face downward pressure from a likely pickup in the sales of foreclosed and distressed properties and reduced buying investors and speculators.
Prices in the 20 cities rose 4.3 percent year over year, beating expectations for a rise of 4.0 percent.
Las Vegas posted the biggest monthly rise on a seasonally adjusted basis at 2.4 percent, followed by a 1.7 percent increase in San Diego, the latest Case-Shiller data showed.
"Higher year-over-year price gains plus strong performances in the Southwest and California, regions that suffered during the housing bust, confirm that housing is now contributing to the economy," Blitzer said.
Housing contributed 10 percent to the overall U.S. economic growth in the third quarter, while the sector represented less than 3 percent of gross domestic product, he said.
Last week, the government said U.S. GDP expanded at a stronger-than-expected 3.1 percent annualized pace in the third quarter.
Excluding seasonal factors, however, home prices in 12 of the 20 cities fell in October from September as home values tend to decline in fall and winter, Blitzer said.
Chicago experienced the largest non-seasonally adjusted decline at 1.5 percent, followed by a 1.4 percent fall in Boston.

US home prices rise in October from previous year

 US home prices rose in most major cities in October compared with a year ago, pushed up by rising sales and a decline in the supply of available homes. Higher prices show the housing market is improving even as it moves into the more dormant fall and winter sales period.
The Standard & Poor's/Case-Shiller national home price index released Wednesday increased 4.3 percent in October compared with a year ago. That's the largest year-over-year increase in two and a half years, when a homebuyer tax credit temporarily boosted sales.
Prices rose in October from a year ago in 18 of 20 cities. Phoenix led all cities with a 21.7 percent gain, followed Detroit, where prices increased 10 percent. Prices declined in Chicago and New York.
Home prices fell in 12 of 20 cities in October compared with September. Monthly prices are not seasonally adjusted, so the decreases reflect the end of the peak buying season.
Still, the broader trend is encouraging. October marked the fifth straight month of year-over-year gains, after nearly two years of declines. Prices rose in mid-2010 in the final months before the tax credit expired. They had fallen sharply in 2008 and 2009.
"It is clear that the housing recovery is gaining strength," said David Blitzer, chairman of the index committee at S&P Dow Jones Indexes.
The improvement in housing is adding to economic growth and most analysts expect that to continue in 2013.
But automatic tax increases and spending cuts that are set to take effect next week could drag down growth. The White House and Congress have so far failed to reach agreement on a way to avoid the "fiscal cliff." President Barack Obama and congressional lawmakers will return to Washington on Thursday to resume talks.
"We expect home price appreciation to continue for the foreseeable future, because inventories are lean amid rising sales," said Joseph LaVorgna, chief U.S. economist at Deutsche Bank. "This assumes that a resolution to the 'fiscal cliff' is found ... otherwise, the recent positive trend in housing would most certainly be in jeopardy along with the rest of the current economic expansion."
Prices nationwide have recovered to about the same level as in the fall of 2003, according to the Case-Shiller index. They remain about 30 percent below the peak reached in the summer of 2006.
The S&P/Case-Shiller index covers roughly half of U.S. homes. It measures prices compared with those in January 2000 and creates a three-month moving average. The October figures are the latest available.
Solid gains in home prices have helped drive a modest recovery in the housing market. Rising prices encourage more potential buyers to come off the sidelines and purchase homes. And more people may put their homes on the market as they gain confidence that they can sell at a good price.
Higher home prices can also make homeowners feel wealthier and more likely to spend more. Consumer spending accounts for about 70 percent of the U.S. economy.
Steady job gains and record-low mortgage rates have also helped propel the housing recovery. And the low supply of houses for sale is encouraging builders to start work on more homes. That should lead to more construction jobs.
The pace of home construction slipped in November but was still nearly 22 percent higher than a year earlier. Builders are on track this year to start work on the most homes in four years.
Builder confidence rose in December for a seventh straight month to the highest level in more than 6½ years, according to a survey released last week by the National Association of Home Builders/Wells Fargo.

US economy could handle short fall over 'cliff'

The economic threat that's kept many Americans on edge for months is nearing reality — unless the White House and Republicans cut a budget deal by New Year's Day.
Huge tax increases. Deep cuts in domestic and defense programs. The likelihood of sinking stock prices, reduced consumer spending and corporate layoffs. The risk of a recession within months.
Still, the start of 2013 may turn out to be far less bleak than feared. For one thing, the two sides may strike a short-term agreement before New Year's that postpones spending cuts until spring. President Barack Obama and members of Congress return to Washington Thursday.
Even if New Year's passed with no deal, businesses and consumers would not likely panic as long as some agreement seemed imminent. The $671 billion in tax increases and spending cuts could be retroactively repealed.
And the impact of the tax increases would be felt only gradually. Most people would receive slightly less money in each paycheck.
"The simple conclusion that going off the cliff necessarily means a recession next year is wrong," says Lewis Alexander, an economist at Nomura Securities. "It will ultimately depend on how long the policies are in place."
It's always possible that negotiations between President Obama and Republican congressional leaders will collapse in acrimony. The prospect of permanent tax increases and spending cuts could cause many consumers and businesses to delay spending, hiring or expanding.
Without any agreement at all for months, the fiscal cliff would cause the U.S. economy to shrink 0.5 percent in the first half of 2013 and fall into recession, the Congressional Budget Office estimates.
But most economists expect a deal, if not by New Year's then soon after. Businesses and consumers will likely remain calm as long as negotiators seem to be moving toward an agreement.
"The atmosphere is more important than whether the talks spill" into next year, said Paul Ashworth, an economist at Capital Economics.
Here's why many are optimistic that a brief fall over the cliff wouldn't derail the economic recovery:
— Though the fiscal cliff would boost taxes by $586 billion for all of 2013, the tax hit for most people would be modest at first. The expiration of Social Security and income tax cuts would be spread throughout 2013. For taxpayers with incomes of $40,000 to $65,000, paychecks would shrink an average of about $1,500 next year. That would be a significant bite over the full year, but the initial hit would be just $130 in January, according to the nonpartisan Tax Policy Center.
— About a third of the tax increases wouldn't touch most Americans. Some would hit businesses. Others, such as higher taxes on investment income and estates, and the expiration of middle-income tax credits, wouldn't come due until Americans filed their 2013 taxes in 2014.
— The Internal Revenue Service has delayed any increases in tax withholding that would otherwise kick in. Without a deal, the top income tax rate for single people with taxable income between about $36,000 and $88,000 would rise from 25 percent to 28 percent. But that won't start to reduce Americans' paychecks in early January, even if no deal is reached by then.
— About $85 billion in spending cuts to defense and domestic programs would take weeks or longer to take effect. That means government agencies wouldn't cut jobs right away.
If a short-term agreement is struck, some taxes would probably still go up. These would include a 2 percentage point cut in Social Security taxes that's been in place for two years. Its expiration would cost the typical household about $1,000 a year. With income gains sluggish, that could dampen consumer spending.
A temporary deal that delays some hard decisions could reduce business and consumer confidence. It would also mean:
— Extended unemployment benefits would end for 2 million people. The federal government's program pays for about 32 weeks of extra benefits, on average, on top of the 26 weeks most states provide. Weekly unemployment checks average about $320 nationwide.
— The stock market would probably drop, though maybe not by much. Many Wall Street analysts expect a partial deal of some kind. "There is starting to become a little bit of an acceptance that we fall off the fiscal cliff," said J.J. Kinahan, a strategist for TD Ameritrade.
— The expiration of the Social Security tax cut and the end of emergency unemployment benefits would likely shave 0.7 percentage point off economic growth next year, the CBO estimates. The economy is now growing at about a 2 percent annual pace.
If no deal at all was reached by January and budget talks dragged on, many businesses might put off investment or hiring. That's why most economists say it would be crucial to reach a deal within roughly the first two months of 2013.
In addition, many more people would be affected if something called the alternative minimum tax isn't fixed.
The financially painful AMT was designed to prevent rich people from exploiting loopholes and deductions to avoid any income tax. But the AMT wasn't indexed for inflation, so it has increasingly threatened middle-income taxpayers. Congress has acted each year for a decade to prevent the AMT from hitting many more people.
If it isn't fixed again, roughly 33 million taxpayers, including married couples with income as low as $45,000 — down from $74,450 in 2011— could face the AMT. Previously, only 5 million taxpayers had to pay it. Taxpayers subject to the AMT must calculate their tax under both the regular system and the AMT and pay the larger amount. Without a fix, a middle-income household would pay an average of $1,231 more, according to the Tax Policy Center.
The IRS has said it assumes Congress and the White House will fix the AMT in a deal to avoid the cliff. If they don't, the IRS will need weeks to reprogram computers and make other adjustments. In the meantime, about 100 million taxpayers couldn't file tax returns early next year because they couldn't determine whether they owe the AMT. Refunds would be delayed.
The gravest scenario would be if the budget talks collapsed and the tax increases and spending cuts appeared to be permanent.
In that case, Macroeconomic Advisors warns that the Dow could plunge up to 2,000 points within days. Businesses would turn gloomier in anticipation of Americans paying higher taxes and spending less.
The economy would shrink at an annual rate of 0.6 percent in the first three months of 2013, estimates Joel Prakken, an economist at Macroeconomic Advisors. That compares with an estimated 1.9 percent growth rate if a deal is reached. CBO forecasts that the unemployment rate would rise to 9.1 percent from the current 7.7 percent.
Last week, Obama and House Speaker John Boehner narrowed their differences on income tax increases and spending cuts. But with the two sides deadlocked, Boehner scheduled a vote on a bill to prevent taxes from rising on those earning less than $1 million a year. Opposition from anti-tax conservatives, and Democrats, forced him to cancel the vote.
The gridlock caused stocks to fall Friday. The Dow Jones industrial average dropped 121 points.
Obama called for a vote on a stripped-down agreement that would raise taxes only on the wealthiest 2 percent of Americans and extend emergency unemployment benefits. Automatic spending cuts would be postponed.
Whatever the outcome, some trends could offset part of the economic damage. The average retail price for gasoline has dropped 15 percent this fall, for example. Lower gas prices give consumers more money to spend elsewhere.
And if the crisis is resolved, as many expect, the boost to business and consumer confidence would encourage more hiring and spending.
"We could end up with a much more robust recovery than anybody's envisioned" if a deal is reached, said David Cote, CEO of Honeywell International.

Future of state estate taxes hangs on U.S. "fiscal cliff"

Falling off the "fiscal cliff" is a bad thing, right?
Not necessarily for some state governments that could begin collecting more in estate taxes on wealth left to heirs if the United States goes over the "cliff," allowing sharp tax increases and federal spending cuts to take effect in January.
In an example of federal and state tax law interaction that gets little notice on Capitol Hill, 30 states next year could collect $3 billion more in estate taxes if Congress and President Barack Obama do not act soon, estimated the Urban-Brookings Tax Policy Center, a Washington think tank.
The reason? The federal estate tax would return with a vengeance and so would a federal credit system that shares a portion of it with the 30 states. They had been getting their cut of this tax revenue stream until the early 2000s. That was when the credit system for payment of state estate tax went away due to tax cuts enacted under former President George W. Bush.
With the return of the credit system next year as part of the "cliff," states such as Florida, Colorado and Texas - which have not collected estate tax since 2004 - could resume doing so. California Governor Jerry Brown has already begun to add the anticipated estate tax revenue into his plans, including $45 million of it in his 2012-2013 revised budget.
Brown may or may not be jumping the gun.
CLOUDY CLIFF AHEAD
The outlook on the "fiscal cliff" coming up at year-end is uncertain. Democratic President Barack Obama has said he hopes for a last-minute deal to avert it. That would need to get done soon, with Congress just now coming back from its holiday break.
Chances of an agreement became more remote last week after Republicans in the U.S. House of Representatives fumbled their own legislative attempt to prevent the fiscal jolt that economists say could trigger a recession.
House Speaker John Boehner abruptly adjourned the chamber for the holidays after failing to gather the votes from within his own party to pass legislation he and other Republicans had drafted, after walking out of negotiations with Obama.
Weeks of inconclusive political drama over the "cliff" have focused largely on individual income tax rates and spending on federal programs such Medicare and Social Security, but many tax issues are also involved, including the estate tax.
At the moment, under laws signed a decade ago by Bush, the estate tax is applied to inherited assets at a rate of 35 percent after a $5 million exemption. That means a deceased person can pass on an inheritance of up to $5 million before any tax applies. Inherited wealth passed to a spouse or a federally recognized charity is generally not taxed.
Obama wants to raise the rate to 45 percent after a $3.5 million exemption. Republicans have called for complete repeal of the estate tax, which they call the "death tax," though Boehner earlier this month called for freezing the estate tax at its present level. It was difficult to determine what the Republicans want after last week's events in the House.
STATES STAND TO GAIN
If Congress and Obama do not act by December 31, numerous Bush-era tax laws will expire, including the one on estate taxes. That would mean the estate tax rate will shoot up next year to the pre-Bush levels of 55 percent after a $1 million exemption.
It would also mean that for the first time in years, a portion of that estate tax would go to the states, through the return of the credit system.
Under that old law, estates paying the tax could get a credit against their federal tax bill for state estate tax payments of up to 16 percent of the estate's value.
If the fiscal cliff were allowed to take hold unaltered by Washington, 30 states would again automatically begin getting their share of federal estate taxes. The state laws are generally written so the state estate tax amounts are calculated under a formula based on the amount of the federal credit.
This would help states that have struggled with lower tax revenues since the 2007-2009 financial crisis and resulting recession, according to research by the Pew Center on the States, though painful federal spending cut backs would also hurt the states.

Former S.African president Mandela 'much better': Zuma

Former South African president and anti-apartheid hero Nelson Mandela is looking much better after more than two weeks in hospital, President Jacob Zuma said on Tuesday.
Zuma, who visited Mandela on Christmas Day, said in a statement that doctors were happy with the progress the elder statesman was making.
"We found him in good spirits. He was happy to have visitors on this special day and is looking much better. The doctors are happy with the progress that he is making," said Zuma.
The 94-year-old Nobel Peace laureate has been in hospital in Pretoria for more than two weeks after being admitted for routine tests. He then underwent surgery to remove gallstones.
Mandela, who came to power in historic elections in 1994 after decades struggling against apartheid, remains a symbol of resistance to racism and injustice at home and around the world.
He has a history of lung problems dating back to when he contracted tuberculosis while in jail as a political prisoner. But this is his longest stay in hospital since he was released from prison in 1990.
He spent time in a Johannesburg hospital in 2011 with a respiratory condition, and again in February this year because of abdominal pains though he was released the following day after a keyhole examination showed there was nothing serious.
Zuma, who has just been re-elected as president of the ruling African National Congress party, last week described Mandela's condition as serious.
"The Mandela family truly appreciates all the support they are receiving from the public. That is what keeps them going at this difficult time," said Zuma.
Periodic statements from the presidency continue to stress that the veteran politician is responding to treatment. No date has been given for his release from hospital.
Mandela spent 27 years in prison, including 18 years on the windswept Robben Island off Cape Town.
After his release, he used his popularity to push for reconciliation between whites and blacks. This reconciliation is the bedrock of the post-apartheid "Rainbow Nation".
Sworn in as South Africa's first black president in 1994, Mandela stepped down in 1999 after one term in office and has largely been absent from public life for the last decade.
His fragile health has prevented him from making any public appearances in South Africa, though he has continued to receive high-profile domestic and international visitors, including former U.S. president Bill Clinton in July.

‘Bumping’ Your Way to Safer Sex With a Smartphone App

Let’s face it.  Teens have sex.  Parents may choose to ignore it, and teens may choose to deny it, but almost 50 percent of American high school students are having sex, according to the U.S. Centers for Disease Control. And each year, millions of those sexually active teens contract sexually transmitted diseases such as chlamydia, gonorrhea, syphilis, herpes and HIV.
Now one doctor hopes to curb the spread of STDs in this tech savvy group with a smartphone app that lets users “bump” their STD status.
It’s called ‘safe bumping,’” said Dr. Michael Nusbaum, the New Jersey developer of MedXSafe, a feature of the new app called MedXCom.  “If you happen to be out at a bar or a fraternity house or wherever, and you meet someone, you can then bump phones and exchange contact information and STD status.”
The app’s special feature, according to Nussbaum, encourages dating singles to go to the doctor for regular STD checks.  Those who screen negative can ask their doctors to document their STD-free status on the app, allowing users to share the information with whomever they choose.
An alarming 19 million new sexually transmitted infections occur each year, and rates of chlamydia and gonorrhea are on the rise, according to a new report released this month by the CDC.  More than 1.4 million chlamydia infections were reported in 2011, up 8 percent from the previous year.  Cases of gonorrhea were up by 4 percent, marking the second consecutive year of increases.
Nearly half of all infections occur in young people, between the ages of 15 to 24, a group that can be particularly devastated by the associated health effects.
“[Some] undetected and untreated STDs can increase a person’s risk for HIV and cause other serious health consequences, such as infertility,” said Mary McFarlane, an acting chief in the Division of STD Prevention at the CDC.  Harnessing modern social networking technology to prevent these infections may appeal to a younger tech-savvy generation.
MedXSafe is just one of several Internet-based programs devoted to easing confidential STD-status sharing between sexual partners.  Services like Qpid.me, whose slogan is Spread the Love, Nothing Else and U Should Know, designed by a former college student and his girlfriend, also allow their users to check on a partner’s STD status.
But could these services offer a false sense of security to teens who believe that, with a simple phone bump, they have the green light to have unprotected sex?
“It can take months for HIV to show up on a test,” said Renee Williams, executive director of SAFE, a nonprofit organization dedicated to abstinence education.  “So you can test negative today, go out on Friday night and have sex, and then get retested later and find out that you had HIV all along.”
The app does nothing to prevent unplanned pregnancy, and may even encourage high-risk behaviors that young people might otherwise not have been tempted to try, said Williams.
Nor is the app likely to be completely reliable, said Dr. J. Joseph Speidel, director of communication at the Bixby Center for Global Reproductive Health.
“Does it come with a condom?” asked Dr. Richard Besser, ABC’s chief health and medical editor, who’s also a pediatrician and former acting director at the CDC.
But the app’s creator said it does promote regular STD testing and encourages potential partners to openly discuss safe sex practices.
“We’re recognizing that this behavior is going to take place no matter what we do or what we say,” said Nusbaum.  “I have friends that are nuns and I’ve run this by them, and they also agree that it’s promoting safer behaviors.”
Although each program promises to keep health information strictly confidential, none are immune from cyber attacks.
But such attacks would not expose any users who have an STD, according to Nusbaum.  MedXSafe does not allow doctors to upload information about any tests that come back positive, including HIV.  A user with an infection is simply treated for the STD and then retested.  And that user is only confirmed STD-free via the app once subsequent test results come back negative.
Still, it is too early to tell whether these services will become popular with teens.  Lingering social stigma surrounding STDs might make potential partners reluctant to mention such an app when out at a party.
“It’s a big personal step to bring up using such an app,” said Noah Bloom, creator of a smartphone app called Jiber, which uses the same “bump” technology to electronically connect new friends.  “Who really wants anything in the way of getting lucky?

Cardiologist Used Ethanol Shot to the Heart to Save British Man's Life

A cardiologist in England gained international attention when he used an unconventional procedure -- a shot of basic alcohol to the heart -- to stop an unusual cardio rhythm in an elderly patient.

Dr. Tom Johnson, who carried out the procedure at the Bristol Heart Institute Hospital in Bristol, England, said Ronald Aldom, 77, was doing "fantastically well" after Johnson and his team used pure ethanol to treat Aldom's rapid heartbeat, a condition called ventricular tachycardia, or VT, about six weeks ago. VT, which starts in the lower two chambers of the heart -- the ventricles -- can be life-threatening if it goes untreated.

"He's got a lot of life to live," Johnson said.

It may seem like a story lifted out of "Pulp Fiction," but treating VT with ethanol, though rare, is an accepted method that has been used for years. What was noteworthy about Johnson's procedure was that he had never used ethanol to treat VT before, nor had it ever been done in that part of the United Kingdom.

"[Aldom] was at a point where he felt he had no other option and was kind of facing death," Johnson said. "While it sounds like a very barbaric treatment, it was a very rewarding one, [but] very high risk."

Typically, a radio frequency catheter ablation is the treatment choice for someone with VT. A radio frequency catheter is an electrical probe that is threaded into the heart and uses low-voltage electricity to kill the heart tissue around the area causing the arrhythmia. This prevents the tissue from continuing to produce the abnormal rhythm.

But Johnson said his colleagues had already tried that technique on Aldom, who had also previously endured heart attacks, without success -- scar tissue that forms after heart attacks can reject the electrical treatment.

"It was complicated by the fact that [Aldom] had severe damage to his heart already," Johnson said. "It got to the point where this poor man was like, 'please shut it off and let me die.'"

Ethanol ablation works in the same way in that it also selectively destroys heart tissue, but it is more commonly used to treat hypertrophic cardiomyopathy, a condition in which the heart muscle is thick or "bulky," Johnson said. While he had used ethanol to treat hypertrophic cardiomyopathy before, to use it on Aldom was a last resort.

"This guy had no other option, which is why we were able to do something we had never done before," Johnson said.

The first step, Johnson said, was for him and his team to electronically map the heart to find and isolate the tissue that was causing the abnormal rhythm. Once the problem artery was located, Johnson's team fed a wire into the vein graph and inflated a balloon to block the artery. Through that balloon, Johnson said they injected the ethanol while the patient was under anesthetic, killing off the problem tissue.

Destroying the tissue creates a controlled, "selective" heart attack, which can be painful, Johnson said, but it allows the heartbeat to return to normal.

Using ethanol can have risky complications, Johnson said, because not only does it kill tissue, it can also kill some of the electrical function of the heart -- Aldom was already using a pace maker. Another risk, Johnson said, was that the balloon could shift, killing more tissue than intended. But his procedure came through successfully.

Dr. Richard Page, the chairman of the department of medicine at the University of Wisconsin School of Medicine and Public Health and a past-president of the Heart Rhythm Society in the United States, agreed that using ethanol to treat VT was "not a routine procedure at all.
