Euro survives 2012, further tests in store

BRUSSELS: The battered euro, written off as a dud many times during a crisis-wracked year, appears to have survived 2012, but 2013 could prove just as difficult if the economy continues to struggle.

It finished the year strongly after the 17 eurozone nations earlier this month nailed down a deal to supply long-delayed bailout funds to Greece to keep the country afloat, and the bloc intact.

Athens in turn delivered on its part of the bargain -- more stinging austerity, economic reforms and a tight budget -- all with the aim of cutting its massive debt burden to a more sustainable 124 percent of GDP by 2020.

Then progress towards tighter economic and fiscal coordination in the eurozone, and a key first step towards a shared bank supervision regime, rounded out the gains, leaving the Europe in much better shape than seemed likely at the beginning of the year.

"Many observers felt it was all over for Greece (and its) ... remaining in the eurozone. As year-end approaches, we know that these Casandras were wrong," EU Economics Commissioner Olli Rehn said.

For many months, all analysts could talk about was Greece's likely exit from the eurozone and what it would mean for the bloc's future.

Now, "the likelihood of a member state leaving the eurozone is gone," said Janis Emmanouilidis of the European Policy Centre (EPC) think-tank.

Reflecting the change, Standard and Poor's raised Greece's sovereign debt rating by a massive six notches because of what it termed the "strong determination of ... (eurozone) member states to preserve Greek membership."

Greek Finance Minister Yannis Stournaras said the decision "was a very important one that created a climate of optimism. But we know that the road is still long and hard, the hour is not one for easing up."

Analysts also highlighted agreement on the eurozone's Single Supervisory Mechanism (SSM) to regulate its banks, a first step in ring-fencing lenders who get into trouble and threaten financial disaster.

Perhaps the key breakthrough, giving purpose and backing to the other reforms, was a commitment by European Central Bank head Mario Draghi over the summer months to do anything necessary to save the euro.

In September, Draghi said the ECB would buy up the sovereign debt of any eurozone member state without limit, if that is what it took to keep the financial markets in check.

This pledge of 'Outright Monetary Transactions' meant markets' could no longer enjoy a one-way bet against a member state as the ECB could step in on its side.

The immediate result was a sharp easing in borrowing costs, especially for Spain and Italy which had been tipped to follow Greece, Ireland and Portugal in needing a bailout.

That change, backed up a 100 billion euros eurozone lifeline for its banks, allowed the Spanish government to hold the line.

By year-end, few were talking of Madrid as the next debt crisis casualty, with its banks also being stabilised at a much lower-than-expected cost of some 40 billion euros.

Some analysts said it was important not to get too carried away, however.

The outlook for the next two years "looks less unsettled and will be concerned above all with implementing the new supervisory regime and winding up mechanism for the banks," CM-CIC Securities analysts said in a note.

For Barclays, talks on closer integration in the eurozone could prove heated and even chaotic, with the emergence of deep differences running the risk of stoking fresh tensions on the markets.

Above all, the uncertainties for the coming year are political, with elections due in Italy and then Germany, while the situation in "Greece is still on a knife-edge," said Emmanouilidis at the EPC.

The economic outlook is also clouded, with the eurozone in recession and expected to slow further while unemployment runs at a record 11.7 percent, rising to unprecedented levels around 25 percent in Spain and Greece.

Against that background, German Chancellor Merkel's guarded words on the outlook seem appropriate.

"We have already achieved a lot but I think we still have a very difficult time ahead," Merkel said after the last EU leaders summit of the year earlier this month.

Pictures: Fungi Get Into the Holiday Spirit

Photograph courtesy Stephanie Mounaud, J. Craig Venter Institute

Mounaud combined different fungi to create a Santa hat and spell out a holiday message.

Different fungal grow at different rates, so Mounaud's artwork rarely lasts for long. There's only a short window of time when they actually look like what they're suppose to.

"You do have to keep that in perspective when you're making these creations," she said.

For example, the A. flavus fungi that she used to write this message from Santa grows very quickly. "The next day, after looking at this plate, it didn't say 'Ho Ho Ho.' It said 'blah blah blah,'" Mounaud said.

The message also eventually turned green, which was the color she was initially after. "It was a really nice green, which is what I was hoping for. But yellow will do," she said.

The hat was particularly challenging. The fungus used to create it "was troubling because at different temperatures it grows differently. The pigment in this one forms at room temperature but this type of growth needed higher temperatures," Mounaud said.

Not all fungus will grow nicely together. For example, in the hat, "N. fischeri [the brim and ball] did not want to play nice with the P. marneffei [red part of hat] ... so they remained slightly separated."

Obama, Congress Waving Bye-Bye Lower Taxes?

The first family arrived in the president's idyllic home state of Hawaii early today to celebrate the holidays, but President Obama, who along with Michelle will pay tribute Sunday to the late Sen. Daniel Inouye at the National Memorial Cemetery of the Pacific, could be returning home to Washington sooner than he expected.

That's because the President didn't get his Christmas wish: a deal with Congress on the looming fiscal cliff.

Members of Congress streamed out of the Capitol Friday night with no agreement to avert the fiscal cliff -- a massive package of mandatory tax increases and federal spending cuts triggered if no deal is worked out to cut the deficit. Congress is expected to be back in session by Thursday.

It's unclear when President Obama may return from Hawaii. His limited vacation time will not be without updates on continuing talks. Staff members for both sides are expected to exchange emails and phone calls over the next couple of days.

Meanwhile, Speaker of the House John Boehner is home in Ohio. He recorded the weekly GOP address before leaving Washington, stressing the president's role in the failure to reach an agreement on the cliff.

"What the president has offered so far simply won't do anything to solve our spending problem and begin to address our nation's crippling debt," he said in the recorded address, "The House has done its part to avert this entire fiscal cliff. ... The events of the past week make it clearer than ever that these measures reflect the will of the House."

Senate Minority Leader Mitch McConnell echoed the sentiment while lamenting the failure to reach a compromise.

"I'm stuck here in Washington trying to prevent my fellow Kentuckians having to shell out more money to Uncle Sam next year," he said.

McConnell is also traveling to Hawaii to attend the Inouye service Sunday.

If the White House and Congress cannot reach a deficit-cutting budget agreement by year's end, by law the across-the-board tax hikes and spending cuts -- the so called fiscal cliff -- will go into effect. Many economists say that will likely send the economy into a new recession.

Reports today shed light on how negotiations fell apart behind closed doors. The Wall Street Journal, citing unnamed sources, reported that when Boehner expressed his opposition to tax rate increases, the president allegedly responded, "You are asking me to accept Mitt Romney's tax plan. Why would I do that?"

The icy exchange continued when, in reference to Boehner's offer to secure $800 billion in revenue by limiting deductions, the speaker reportedly implored the president, "What do I get?"

The president's alleged response: "You get nothing. I get that for free."

The account is perhaps the most thorough and hostile released about the series of unsuccessful talks Obama and Boehner have had in an effort to reach an agreement about the cliff.

Unable to agree to a "big deal" on taxes and entitlements, the president is now reportedly hoping to reach a "small deal" with Republicans to avoid the fiscal cliff.

Such a deal would extend unemployment benefits and set the tone for a bigger deal with Republicans down the line.

In his own weekly address, Obama called this smaller deal "an achievable goal ... that can get done in 10 days."

But though there is no definitive way to say one way or the other whether it really is an achievable goal, one thing is for certain: Republican leadership does not agree with the president on this question.

Of reaching an agreement on the fiscal cliff by the deadline, Boehner said, "How we get there, God only knows."

Squash: World No. 1 Nicol David extends haul of World Open titles

GRAND CAYMAN, Cayman Islands: Nicol David extended her record of World Open titles to seven from eight finals on Friday with a balanced performance and great patience to beat English third seed Laura Massaro.

The Malaysian heroine's 11-6 11-8 11-6 victory silenced critics who had suggested younger rivals were closing the gap on the 29-year-old champion.

Massaro forced many long rallies and even led 7-5 in the second game, but David responded well to the important moments which followed.

She mixed containment with well-timed drops and lightning-quick changes of direction that prevented her opponent from getting a crucial foothold in the match.

The outcome was that David only dropped one game throughout the entire tournament, but she had to focus harder and for longer in the final than in any of her four other encounters.

Her relief and joy at surviving the perpetual pressure of expectations yet again was smilingly obvious.

She held her head in both hands, then placed her hands high on the court, and finally caressed the ball affectionately against a wall before allowing herself to accept that no more was required of her racket.

Then her words reflected the frequent struggle between doubt and self-confidence.

"I can't believe it," she said. "I just can't believe it.

"I am just so pleased with my match. Laura pushed me every point. There was no point where I could let up because she was just on it every point. She played a very good match."

David knew the danger well as Massaro is one of the few players to have beaten her twice. However, she did so last year and, although the challenger has improved further since then, the champion at her best has too, perhaps just as much.

Two of the most crucial moments came when David got back to 7-7 in the pivotal middle game and then nosed ahead to 8-7 with a disputed point.

The levelling rally saw brilliantly nimble retrieves from David, plus some patient backhand wall straight driving with a tight little backhand drop to finish it.

That was followed in the next rally by a marginally mistimed backhand drive by Massaro, which caused the ball to come away from the wall and resulted in her slightly impeding David.

A penalty stroke was awarded, Massaro's video review appeal failing to get the decision overturned.

David pushed hard to capitalise, offered a rare fist pump when she broke through to a two-game lead, and was quickly five points up in the third and motoring away.

"I am a little bit disappointed with that," said Massaro, who had saved a match point in a long and hard semi-final with Raneem El Weleily, the second-seeded Egyptian, and may have paid a price in the third game of the final.

"It was just a few points here and there and that's all the difference," she said. "The middle of the games were so crucial and that's what I have to work on.

"It's still pretty rare that she is beaten. We are still training hard and improving and she's rising to the challenge."

To do that well as she moves through her 30th year, David may need to select peaks more carefully for the tournaments she really wants to win.

But at her best, she is still too fine an athlete and too steady a rallyer for everyone, even during her moments of doubt. Her high profile among the all-time greats is likely to rise yet further.

Why does my external hard drive only show 2.2TB?

External hard drives are exceptionally useful for expanding storage capabilities for both backups and data management. While external hard drives are often sold in preconfigured packages by manufacturers, another popular option is to purchase an external hard-drive enclosure and then use any drive of your choice in it. This is beneficial because as your demands for storage increase, you can replace the enclosure's drive with a larger one.

These days, the availability of hard drives with 4TB of storage are enticing for people to swap into their existing enclosures; however, when doing so they may find that the system will only recognize 2.2TB of the drive, regardless of how they partition or format the device.

While modern file-system formats such as HFS+, NTFS, and ExFAT ought to handle volume sizes of between hundreds of gigabytes to zettabytes, and though operating systems like OS X have increased the maximum volume size from 2TB to 8EB (exabytes) over the years, there are hardware limitations that may limit the size of the volume that can be used. If you are using an older drive enclosure for your large hard drive, then the controllers on it may not be capable of handling over 2.2TB, regardless of the software environment being used around it.

This problem happens because of the use of LBA (logical block addressing) in modern hard-drive controllers coupled with a hardware-based limit of how many blocks can be included in the LBA scheme. Early LBA controllers used 32-bit (or lower) addressing coupled with a maximum supported block size of 512 bytes. This means they support up to 2^32 or 4,294,967,296 blocks for a device, and with each block being 512 bytes, this translates to a maximum of 2,199,023,255,552 bytes, or 2.199TB.

Unfortunately in many cases these limits are hard-coded in enclosure's firmware, so even though modern drives use 4,096-byte sectors, the system will still only address these sectors as 512 bytes in size, resulting in both a waste of space and degraded performance.

The only way around this problem is to replace your drive enclosure with a new one that has proper support for both 48-bit (or greater) LBA and 4,096-byte sectors in hard drives. Luckily most enclosures on the market today do support this, so if you run into this problem, you should be up and running in no time.

Obama Still an 'Optimist' on Cliff Deal

Mandel Ngan/AFP/Getty Images

WASHINGTON D.C. – Ten days remain before the mandatory spending cuts and tax increases known as the “fiscal cliff” take effect, but President Obama said he is still a “hopeless optimist” that a federal budget deal can be reached before the year-end deadline that economists agree might plunge the country back into recession.

“Even though Democrats and Republicans are arguing about whether those rates should go up for the wealthiest individuals, all of us – every single one of us -agrees that tax rates shouldn’t go up for the other 98 percent of Americans, which includes 97 percent of small businesses,” he said.

He added that there was “no reason” not to move forward on that aspect, and that it was “within our capacity” to resolve.

The question of whether to raise taxes on incomes over $250,000 remains at an impasse, but is only one element of nuanced legislative wrangling that has left the parties at odds.

For ABC News’ breakdown of the rhetoric versus the reality, click here.

At the White House news conference this evening, the president confirmed he had spoken today to Senate Majority Leader Harry Reid, D-Nev., and House Speaker John Boehner, R-Ohio, although no details of the conversations were disclosed.

The talks came the same day Speaker Boehner admitted “God only knows” the solution to the gridlock, and a day after mounting pressure from within his own Republican Party forced him to pull his alternative proposal from a prospective House vote. That proposal, ”Plan B,” called for extending current tax rates for Americans making up to $1 million a year, a far wealthier threshold than Democrats have advocated.

Boehner acknowledged that even the conservative-leaning “Plan B” did not have the support necessary to pass in the Republican-dominated House, leaving a resolution to the fiscal cliff in doubt.

“In the next few days, I’ve asked leaders of Congress to work towards a package that prevents a tax hike on middle-class Americans, protects unemployment insurance for 2 million Americans, and lays the groundwork for further work on both growth and deficit reduction,” Obama said. ”That’s an achievable goal.  That can get done in 10 days.”

Complicating matters: The halls of Congress are silent tonight. The House of Representatives began its holiday recess Thursday and Senate followed this evening.

Meanwhile, the president has his own vacation to contend with. Tonight, he was embarking for Hawaii and what is typically several weeks of Christmas vacation.

However, during the press conference the president said he would see his congressional colleagues “next week” to continue negotiations, leaving uncertain how long Obama plans to remain in the Aloha State.

The president said he hoped the time off would give leaders “some perspective.”

“Everybody can cool off; everybody can drink some eggnog, have some Christmas cookies, sing some Christmas carols, enjoy the company of loved ones,” he said. “And then I’d ask every member of Congress, while they’re back home, to think about that.  Think about the obligations we have to the people who sent us here.

“This is not simply a contest between parties in terms of who looks good and who doesn’t,” he added later. “There are real-world consequences to what we do here.”

Obama concluded by reiterating that neither side could walk away with “100 percent” of its demands, and that it negotiations couldn’t remain “a contest between parties in terms of who looks good and who doesn’t.”

Boehner’s office reacted quickly to the remarks, continuing recent Republican statements that presidential leadership was at fault for the ongoing gridlock.

“Though the president has failed to offer any solution that passes the test of balance, we remain hopeful he is finally ready to get serious about averting the fiscal cliff,” Boehner said. “The House has already acted to stop all of the looming tax hikes and replace the automatic defense cuts. It is time for the Democratic-run Senate to act, and that is what the speaker told the president tonight.”

The speaker’s office said Boehner “will return to Washington following the holiday, ready to find a solution that can pass both houses of Congress.”
