Simpson and Piazza have been dating since June 2011 but have now broken up over the Thanksgiving holiday, claiming that their busy schedules got in the way.? ?Vincent has been working a lot, so he hasn?t been able to spend that much time with Ashlee, which has caused some problems,? an undisclosed source informed Page Six of the New York Post.? Adding, ?It was a mutual agreement to split, but things have been bumpy for a little while, so perhaps they might reconcile.? There may be some truth to their decision to split.? At the moment the younger Simpson is gearing up to release her fourth studio album.? Could spending time in the studio and raising her son Bronx who she shares with Pete Wentz be to blame??

Hurricane center pushes to improve storm surge warnings

MIAMI (Reuters) - Friday marks the end of an Atlantic-Caribbean hurricane season where the greatest devastation was caused by water rather than wind, U.S. National Hurricane Center Director Rick Knabb said.

Accordingly, the center is ramping up efforts to develop new warnings that better convey the threat from the deadly storm surge pushed ashore by monsters like Sandy, which slammed the U.S. Northeast in October.

"We've been working toward a new storm surge warning for a few years now," Knabb told Reuters in an interview at the hurricane center in Miami. "And Debby, Isaac and Sandy show us how much we really need to hit the accelerator on getting that storm surge warning out the door."

Debbie, Isaac and Sandy were three of the four storms that hit the United States during the 2012 season.

Starting with a meeting next week, the forecasters will review their warning systems and speed up development of a separate warning system for storm surge in hopes of having an experimental version ready to test in the next couple of years, Knabb said.

It will include a high-resolution graphic showing how high the surge would grow and how far inland it would reach at various times. Storm surge rarely correlates neatly with wind strength, Knabb said.

"Hurricane-force winds and storm surge doesn't always occur in the same places or at the same times when a storm approaches," he said. "Where the storm surge occurs is very dependent upon details of the coastline and the elevations and all that."

The United States is increasingly at risk from storm surge. Much of its densely populated Atlantic and Gulf coastlines lie less than 10 feet above sea level, and the seas are gradually rising as the Earth warms and ice caps and glaciers melt.

At the same time, the population in the hurricane region is growing rapidly. From 1990-2008, population density increased by 32 percent in Gulf coastal counties, 17 percent in Atlantic coastal counties, and 16 percent in Hawaii, according to the 2010 Census.

Much of the nation's commerce also depends on seaports and the transit systems that link to them.

Improving the storm surge warning system not only could help tailor evacuation orders as a storm approaches, it could help homeowners, business owners and governments know where and how to fortify before the next season comes.

"We can't hope that it doesn't happen again ... because it will. It's just a matter of when, not if," Knabb said.

Superstorm Sandy highlighted the need for more flexible warnings and greater focus on storm surge.

RAMPAGE

After killing 69 people on a rampage through the Caribbean, Sandy hit the densely populated northeastern United States in October, killing at least 131 more people and causing an estimated $71.3 billion of damage in New York and New Jersey.

It leveled entire beach towns, flooded subways and tunnels, paralyzed the nation's financial capital and knocked out power to 8.5 million customers in 21 states.

The behemoth storm was more than 900 miles wide as it churned northward up the Atlantic. It approached New Jersey as a hurricane, a spiraling system that draws energy from warm seas and has its strongest winds around the center.

Just offshore, it morphed into an extra-tropical "Nor'easter," a colder storm that draws energy from the atmosphere and spreads the strongest winds over a broader area. That did not lessen the danger.

"The ocean was churned up over a long period of time by this massive wind field. Tropical or not, we knew the storm surge hazard was going to be significant," said Knabb, who had warned for days that Sandy would push a surge of seawater up to 11 feet high over parts of New York and New Jersey.

"That's what did most of the damage in Sandy," he said. "We had a huge area impacted by storm surge and waves and most of that area did not get hurricane-force winds."

The hurricane center worked closely with local government officials who ordered evacuations in low-lying areas, and waged an intense media campaign to get the warnings out.

But since Sandy was not expected to be a hurricane or tropical storm at landfall, it didn't fit neatly into the hurricane center's standard package of warnings and graphics that focus on wind.

Hurricane watches and warnings, which are issued by local governments on the advice of forecasters, are based on expectations for strong winds within 36 to 48 hours.

The forecasters did not want hurricane warnings issued only to have them taken down when Sandy made its anticipated transition to an extra-tropical storm near the shore. They feared that would create a false impression that the danger was over just when it was greatest.

"It would have really caused a lot of confusion for a lot of people trying to make decisions and evacuate," Knabb said.

Another option - "faking it" and pretending it was still a hurricane when it wasn't - would have been an obvious deception, Knabb said.

"We do need to have some credibility and call it like we see it," he said.

Instead, the hurricane center continued to issue advisories in the regular format and through its regular distribution system, stressing the storm surge danger and referring people to their local Weather Service office for specific flood projections.

In all, the 2012 season brought 19 tropical storms, 10 of which strengthened into hurricanes.

That made it a busier-than-average year that topped the seasonal forecasts issued in the spring by government and private meteorologists.

But none of the storms that hit the United States this year were "major" hurricanes on the Saffir-Simpson scale that ranks them into five categories according to their wind strength. Most were not even hurricanes, which are tropical cyclones with sustained winds of at least 74 miles per hour.

Beryl was a tropical storm when it swirled ashore in Florida and soaked the southeastern United States in May, before the season officially began. Debby was also a tropical storm when it dumped 2 feet of rain over northern Florida in June, sending thousands fleeing from rapidly rising rivers.

Tropical Storm Isaac delayed the start of the Republican National Convention when it brushed by Tampa, Florida. It strengthened into a hurricane that flooded the Mississippi and Louisiana coasts and put New Orleans' refurbished levees to the test.

Despite storm surges that topped 12 feet, the elaborate defenses built to protect the city after the 2005 Hurricane Katrina disaster withstood the onslaught.

Argentina wins debt reprieve, default averted for now

NEW YORK (Reuters) - Argentina has won a reprieve against having to pay $1.33 billion next month to "holdout" investors who rejected a restructuring of its defaulted debt and have waged a long legal battle to be paid in full.

A U.S. appeals court granted an emergency stay order on Wednesday that gives Argentina more time to fight a debt ruling favoring the holdout creditors and eases investor fears of a new default as early as next month.

Last week, U.S. District Judge Thomas Griesa ordered Argentina to deposit the $1.33 billion payment by December 15 for investors who rejected two restructurings of bonds left over from its massive 2002 default.

Griesa's order raised the risk of a technical default on about $24 billion worth of debt because it meant that if Argentina sticks to its position of not paying the holdouts, it would also be barred from paying investors who agreed to take a severe haircut in two debt exchanges in 2005 and 2010.

Branding the holdouts as "vulture funds," the government has vowed never to pay them and it swiftly appealed Griesa's ruling.

Argentina argued that, if left to stand, the order would make future restructurings impossible for countries facing debt crises because creditors would have no incentive to exchange their bonds at a discount.

However, some legal experts said Griesa's order would not have such broad ramifications because Argentina hurt its own cause in refusing to pay the holdouts, and that Griesa's ruling focused on the government's behavior in this specific case.

Griesa has often voiced frustration with Argentina in court and was riled by recent statements from government officials saying that the country would defy his orders.

In its decision on Wednesday, the 2nd U.S. Circuit Court of Appeals put off until well into 2013 a ruling on whether or not Argentina will have to pay in full the holdouts who refused to participate in its two restructurings, which paid less than 30 cents on the dollar.

"The extension of the stay brings back rationality and due process to a litigation that was being rushed through in a manner that understated the importance of the huge precedent that the district judge was seeking to set," said Vladimir Werning, an emerging markets economist at JPMorgan in New York.

Both Argentina and bondholders who took part in the debt exchanges filed appeals to the 2nd Circuit against Griesa's order. The appeals court will hear oral arguments on February 27.

Argentina's economy ministry said the appeal court's decision "ensures normal performance of Argentina's debt payments in December."

"The threat of default has been removed for now," said Ignacio Labaqui of emerging markets consultancy Medley Global Advisors.

"This is really good news for Argentina and exchange bond holders," he added. "The ruling came faster than expected, which sends the message that Griesa's decision may have been too harsh, from the point of view of the appeals court."

Lead holdout investors Elliott Management Corp and Aurelius Capital Management both declined to comment.

Lawyers for the holders of Argentina's exchanged bonds, who will now be paid a combined $3.3 billion in December as scheduled, welcomed the 2nd Circuit's order.

"The stay ensures that the exchange bondholders will receive their rightful payments through December, and until the Court can carefully consider the significant issues and interests that are involved before rendering its final ruling," said the statement from law firm Boies Schiller & Flexner LLP.

iOS 7 wants: Better email attachment handling

iOS 7 wants: Better email attachment handling

Almost 6 years after it was introduced, you still can't attach files to emails in iOS. While iOS 6 has introduced a method to attach photos and videos to in-progress emails, it suffers from poor discoverability, and only works with content from the Photos app. If you want to attach any other file to an email, it's a usability disaster.

Adding photo or video attachments to in-progress emails is done via the same pop-up menu originally introduced in IOS 3 for cut, copy, and paste. You have to tap the screen to get the popup, tap a tiny, obscure arrow button to get more options, and then tap to add the attachment.

An easy to find, easy to use attachment button would be simpler. It's a solution employed by third-party apps like Facebook, email clients like Gmail and Sparrow, and the official Twitter app and Tweetbot.

Some of these are more elegant than others, but all of them are more discoverable. And that's still only for photos and videos. What about files?

Emailing, and including files as attachments in email, is a common task and something that takes only a few seconds on the Mac with OS X. Trying to attach a non-photo or video file on an iPhone or iPad with iOS takes an annoying amount of time and causes an unreasonable amount of frustration. Here's some blog-theater by way of example:

"Hey, Rene, can you email me the dates for that trip?"

"Sure, Kevin." I grab my iPhone, open the Mail app, add Kevin as the recipient, add the subject "trip", paste in the dates, then--

"Could you also attach that outline for discussion topics?"

"Um..."

My only option now is to copy the contents of the email, trash it, go to the app I wrote the topics in, find the file, tap share, tap email, add Kevin again, add the subject again, paste in the dates again--

Shit. I deleted the app I wrote the topics in. A hotter, newer app came out and I started using that instead, and even though both use iCloud, neither has any idea the other exists so... I re-download the old app and pray the data is either still there, or magically comes back from the cloud.

"And those two PDF files about that thing?"

Double shit. Both those PDF files are in different PDF apps, one in a simple reader, the other one in an app that supports annotation. Now I have to send the discussion topics from one app, and each of the PDF files from their apps. That's three separate emails, and nothing approaching a thread.

Now Kevin is laughing his ass off at me and asking me to tell him again how the iPhone is easy to use, and I want to punch things.

And the reason for all this is that Apple forgot a cardinal principle of design: unreasonable simplicity sometimes leads to inane levels of complexity.

Apple already uses a blue + button to add contacts. Something like that could work for attachments as well. (I did a mockup along those lines for a pre-iOS 6 article on higher hanging fruit, but I'll update it below.)Tapping the attachment button could bring up a Share Sheet that includes the Photos icon, so you could attach photos as normal, but also any other app icon that contains documents. Tapping an icon would bring up a list view of all the files associated with that app. It's a bit overwrought, but it fits with the existing iOS constructs, including the binding of files to apps, and has the advantage of familiarity-as-a-feature.

Depending on how many file-capable apps are installed, it could create a very dense Share Sheet. It also still requires the user remember which app contains which file.

That's why, for the last couple of years, I've been asking for a simple, flat document repository for iOS -- a Files app that works the same way as the Photos app (or Passbook app for that matter). A Files app for iOS would remove unnecessary cognitive load from users and solve a wide swathe of current usability problems with iOS, including email attachments.

With a document repository, any user file could be attached to any in-progress email, without the need for a Share Sheet, or for the user to remember app ownership. And it would do so in a way that's consistent with how iOS already works, increasing simplicity at the same time.

Nintendo's Wii U Starts Strong - NYTimes.com

In its first week on the market, Nintendo?s new videogame console, the Wii U, sold about as well in the United States as the original Wii did at the same point in its life, according to Nintendo.

In an interview, Reggie Fils-Aime, president of Nintendo of America, estimated that the company sold more than 400,000 Wii U?s here from the product?s introduction on Nov. 18 and last Saturday. Mr. Fils-Aime said that figure was based on sales data Nintendo collected electronically from retailers. He said total American sales for the product were likely higher.

A more complete sales figure for Wii U will come soon when NPD, a research firm that estimates retail sales, releases data for the product?s first week on the market, Mr. Fils-Aime said. He said 475,000 of the original Wiis were sold during the product?s first week on the market in 2006, citing NPD data.

The results are a good sign for the company?s latest product. The Wii was an enormous hit that outsold competing systems from Microsoft and Sony, but its sales have faded in recent years, putting pressure on the Wii U to help lead a turnaround at Nintendo.

?We are essentially sold out at retail,? Mr. Fils-Aime said. ?As soon as we replenish product to retailers, it sells out immediately.?

It?s important to keep in mind that supplies of new game consoles are often very limited when they first go on sale, as manufacturers ramp up production. Nintendo has a very dedicated audience that craves almost anything new the company has to offer, not unlike Apple?s fans. The real test of the Wii U?s durability will come when the product is in better supply and more casual gamers, who don?t dream about Mario and Zelda in their sleep, can more easily buy it.

Mr. Fils-Aime said another of Nintendo?s more recent products, the handheld Nintendo 3DS, was also selling well, racking up sales of 6.4 million units in the United States during its first 21 months on the market. He said Nintendo had sold one million more Nintendo 3DSes than it did an older handheld, the Nintendo DS, during the comparable time period.
