Speed. It's a movie. It's a drug. And it's also something that throngs of internet users the world over cannot get enough of. Thankfully, the wizards at the Fraunhofer Institute for Applied Solid State Physics and the Karlsruhe Institute for Technology have figured out a way to satisfy the unsatisfiable, announcing this week a world record in the area of wireless data transmission. Researchers were able to achieve 40Gbit/sec at 240GHz over a distance of one kilometer, essentially matching the capacity of optical fiber... but, you know, without the actual tether.
The goal here, of course, isn't to lower your ping times beyond where they are already; it's to give rural communities across the globe a decent shot at enjoying broadband. Distances of over one kilometer have already been covered by using a long range demonstrator, which the Karlsruhe Institute of Technology set up between two skyscrapers as part of the project "Millilink". There's no clear word on when the findings will be ported over to the commercial realm, but given the traction we're seeing in the white spaces arena, we doubt you'll have to wait long.
MOORE, Okla. (AP) ? With an ominous storm approaching, the Moore Public School District flashed a text alert to parents: "We are currently holding all students until the current storm danger is over. Students are being released to parents only at this time."
Parents had a gut-wrenching choice, and only a few minutes to make it. Trust the safety of the seemingly solid school buildings and the protection of trained teachers and staff. Or drive frantically ahead of a massive tornado and attempt to take their children safely home.
"Something clicked in my head and said that my children would be afraid and they would be safer with me," said Amy Sharp, who jumped in her pickup, peeled off through pounding rain and hail, and pulled her 10- and 12-year-old daughters out Plaza Towers Elementary School.
Sharp survived with her children. But seven of the many remaining students died when the twister ripped down the school's roof and walls.
Exactly how do desperate parents like those in the path of the powerful Oklahoma tornado know when it's best to leave their children in a presumably safe place or race into the face of danger for their sake?
"You have that parent-child draw. That protective factor, where they want to go at any cost, no matter what. The options aren't very good in a tornado if you're thinking about going to rescue your children," said Ronald Stephens, executive director of the National School Safety Center that provides training to schools around the country.
"Which way is the wind going to twist? What's it going to pick up? What won't it pick up? Until someone becomes all-powerful, all-knowing and all-perceiving, it is tough to expect 100 percent perfection from schools and parents," he said.
The Oklahoma tornado provides a good example of the unpredictable death toll that disasters can inflict. Before it flattened Plaza Towers Elementary, the tornado also tore through Briarwood Elementary and ? though the roof collapsed ? everyone at Briarwood appears to have survived. Both schools lacked tornado safe rooms, and at both, students initially were sent to the halls before some teachers squeezed them into seemingly safer places such as closets and bathrooms.
David Wheeler would have liked to race to rescue his 8-year-old son, Gabriel, before the tornado reached Briarwood. But Wheeler had to remain at a separate school where he worked. So he waited until the tornado cleared, then speed down the highway as far as he could and fibbed about being a first-responder to hitch a ride with a sheriff's deputy headed into the disaster zone. Once he got there, he slogged through broken glass and raw sewage to try to get to the school.
Wheeler ended up more injured than his son, who climbed from the rubble with scrapes and bruises after being sheltered by a teacher. Wheeler, meanwhile, had a large red rash on his legs ? he thinks from the sewage ? and multiple cuts and scrapes that required him to get a tetanus shot Tuesday.
"It was just kind of a surreal moment. I didn't know if my son was alive? it was the worst moment of my life," Wheeler said.
Stephens, a former school administrator who lives in Westlake Village, Calif., said the biggest challenge for parents when racing the clock in a disaster is holding emotions in check.
"You're not going to be any good to your child if you take such great risk that you lose your life in the pursuit of attempting to save them when there are others who are onsite who hopefully will also use good judgment," Stephens said.
Simply showing up isn't enough.
"You want to have an entrance plan but also a completion plan. Can you make it out? Can you make it to safety?" he asked rhetorically.
Officials at the Moore School District choose not to dismiss students early. But that, too, is a tough call.
Troy Albert, a principal at Henryville Junior-Senior High in southeastern Indiana, let students out for the day on March 2, 2012, just moments before tornado sirens went off. No injuries were reported among the few staff, students and parents who remained at the school when a tornado packing 175 mph winds destroyed the building. School officials halted people from leaving only when they figured the tornado was within 10 minutes from hitting, fearing that wouldn't allow enough time for people to make it to safety.
"We trusted our protocols and it worked," Albert said. "I was questioned about whether we should dismiss school or whether we should bunker down here. Our decision to do that was based on the fact of the size of the tornado and what was coming. And we figured if you got them a mile away from our school you had a chance for survival."
With about 30-45 minutes of lead time on a potential tornado last year, Julie Hubbard jumped in her car and signed her son out of a Tennessee middle school ahead of the storm.
"There were just dozens of parents who went to pick up their kids that day. I don't know if they just tended to freak out more or what," said Hubbard, who now lives in Fort Gibson, Okla . "Growing up in Oklahoma, we have so many tornadoes. I just wanted to be home with my children."
A couple of hours before ultimately deciding to pick up her children before the tornado barreled through Moore on Monday, Sharp said she called the school office at Plaza Towers Elementary and asked if it was safe for them there. She said the receptionist replied: "They're pretty safe here."

BEIJING (AP) ? A Chinese boat and 16 fishermen seized for ransom by armed North Koreans more than two weeks ago were released Tuesday, easing the latest irritant in relations between the neighboring allies.
Owner Yu Xuejun, who wasn't aboard the boat when it was seized May 5, wrote on his verified microblog that his captain called him at 3:50 a.m. to say the crew and boat were set free. Yu told the state-run Global Times newspaper all of the crewmembers were OK, and other state media reports said the men would resume fishing for a couple of weeks before returning home.
After word of the boat's capture became public over the weekend, China demanded that North Korea release the men, though Chinese officials have not said whether they believe the armed captors were operating on their own or under North Korean government authority. One of China's North Korea watchers said border guards were the likely culprits.
No ransom was paid as was demanded by the North Koreans, Chinese Foreign Ministry spokesman Hong Lei said at a regularly scheduled news conference.
The incident became publicly known only over the weekend when Yu, who had previously reported the seizure to Chinese authorities, began publicizing it as a deadline for a 600,000 yuan ($100,000) ransom drew near.
His pleas for help and fears that his crew might be mistreated were forwarded thousands of times by netizens, and a high-ranking Chinese military officer, Maj. Gen. Luo Yuan, wrote on the Twitter-like Sina Weibo of his fury over the detention.
"North Korea has gone too far! Even if you are short of money, you can't grab people across the border and blackmail," wrote Luo, who has more than 300,000 followers.
The seizure had added to China's frustration with North Korea over its recent tests of nuclear and rocket technologies in defiance of international efforts to curb the country's nuclear ambitions. At the same time, the Chinese government has been under intense pressure to protect Chinese who venture abroad and out to sea for their livelihoods.
A similar abduction a year ago of Chinese fishermen by armed North Koreans caused an uproar in China when they were released ? some of them stripped of everything but their underwear ? saying they had been starved and beaten.
Hong, the Foreign Ministry spokesman, had declined to answer a question Monday about who exactly China believed was behind the boat seizure, but he made clear that Beijing was looking for the North Korean government to deal with the matter.
An expert on North Korea at the Liaoning Academy of Social Sciences in northeast China said he doubted the North Korean government would have had any knowledge of the incident when it happened.
"This incident is purely about a lawless act by the North Korean border police to blackmail our fishermen," said Lu Chao, adding that such things frequently happen to Chinese fishermen working near the border waters.
"Sometimes, if the amount they are asking for isn't too high, the boat owner would just pay it," he said. This time, it might be related to spring food shortages, "so they are asking for a huge ransom."
The owner had previously been reported as saying he received a phone call from North Korea telling him his boat had been in North Korean waters, but that he was certain it had been floating in Chinese waters.

Arranging nanoparticles in geometric patterns allows for control of light with light
HOUSTON -- (May 21, 2013) -- Rice University scientists have unveiled a robust new method for arranging metal nanoparticles in geometric patterns that can act as optical processors that transform incoming light signals into output of a different color. The breakthrough by a team of theoretical and applied physicists and engineers at Rice's Laboratory for Nanophotonics (LANP) is described this week in the Proceedings of the National Academy of Sciences.
Rice's team used the method to create an optical device in which incoming light could be directly controlled with light via a process known as "four-wave mixing." Four-wave mixing has been widely studied, but Rice's disc-patterning method is the first that can produce materials that are tailored to perform four-wave mixing with a wide range of colored inputs and outputs.
"Versatility is one of the advantages of this process," said study co-author Naomi Halas, director of LANP and Rice's Stanley C. Moore Professor in Electrical and Computer Engineering and a professor of biomedical engineering, chemistry, physics and astronomy. "It allows us to mix colors in a very general way. That means not only can we send in beams of two different colors and get out a third color, but we can fine-tune the arrangements to create devices that are tailored to accept or produce a broad spectrum of colors."
The information processing that takes place inside today's computers, smartphones and tablets is electronic. Each of the billions of transistors in a computer chip uses electrical inputs to act upon and modify the electrical signals passing through it. Processing information with light instead of electricity could allow for computers that are both faster and more energy-efficient, but building an optical computer is complicated by the quantum rules that light obeys.
"In most circumstances, one beam of light won't interact with another," said LANP theoretical physicist Peter Nordlander, a co-author of the new study. "For instance, if you shine a flashlight at a wall and you cross that beam with the beam from a second flashlight, it won't matter. The light that comes out of the first flashlight will pass through, independent of the light from the second.
"This changes if the light is traveling in a 'nonlinear medium,'" he said. "The electromagnetic properties of a nonlinear medium are such that the light from one beam will interact with another. So, if you shine the two flashlights through a nonlinear medium, the intensity of the beam from the first flashlight will be reduced proportionally to the intensity of the second beam."
The patterns of metal discs LANP scientists created for the PNAS study are a type of nonlinear media. The team used electron-beam lithography to etch puck-shaped gold discs that were placed on a transparent surface for optical testing. The diameter of each disc was about one-thousandth the width of a human hair. Each was designed to harvest the energy from a particular frequency of light; by arranging a dozen of the discs in a closely spaced pattern, the team was able to enhance the nonlinear properties of the system by creating intense electrical fields.
"Our system exploits a particular plasmonic effect called a Fano resonance to boost the efficiency of the relatively weak nonlinear effect that underlies four-wave mixing," Nordlander said. "The result is a boost in the intensity of the third color of light that the device produces."
Graduate student and co-author Yu-Rong Zhen calculated the precise arrangement of 12 discs that would be required to produce two coherent Fano resonances in a single device, and graduate student and lead co-author Yu Zhang created the device that produced the four-wave mixing -- the first such material ever created.
"The device Zhang created for four-wave mixing is the most efficient yet produced for that purpose, but the value of this research goes beyond the design for this particular device," said Halas, who was recently named a member of the National Academy of Sciences for her pioneering research in nanophotonics. "The methods used to create this device can be applied to the production of a wide range of nonlinear media, each with tailored optical properties."

NEW YORK (AP) ? A couple of stars from TV's "Chuck" and "Smash" will soon be dating on Broadway.
Producers said Monday that Zachary Levi and Krysta Rodriguez will headline the new romantic musical comedy "First Date" by "Gossip Girl" writer Austin Winsberg.
The music and lyrics are by Alan Zachary and Michael Weiner.
"First Date" centers on an uptight young investment banker who meets a serial-dater at a local bistro. A chorus of diners become various characters ? family members, clergy and old lovers.
The show will be seen at The Longacre Theatre beginning July 9 with an opening set for Aug. 8.
The rest of the cast includes Sara Chase ("Arrested Development"), Kristoffer Cusick ("Wicked"), Blake Hammond ("Sister Act"), Kate Loprest ("Boardwalk Empire," and Vicki Noon ("Wicked").
The show, co-produced by The 5th Avenue Theatre, played at A Contemporary Theatre in Seattle last year. It will be directed by Bill Berry, the producing director of The 5th Avenue Theatre.
Levi, who will be in the film "Thor: The Dark World," follows fellow "Chuck" alum Yvonne Strahovski to make his Broadway debut. She made a strong impression in the Lincoln Center Theater revival of Clifford Odets' "Golden Boy."
Rodriguez, who plays Ana Vargas on "Smash," was last on Broadway in "The Addams Family," originating the role of Wednesday Addams alongside Nathan Lane and Bebe Neuwirth. She also was in the original Broadway casts of "In the Heights," ''Spring Awakening" and "Good Vibrations."

BAGHDAD (AP) ? A wave of attacks killed at least 95 people in Shiite and Sunni areas of Iraq on Monday, officials said, pushing the death toll over the past week to more than 240 and extending one of the most sustained bouts of sectarian violence the country has seen in years.
The bloodshed is still far shy of the pace, scale and brutality of the dark days of 2006-2007, when Sunni and Shiite militias carried out retaliatory attacks against each other in a cycle of violence that left the country awash in blood. Still, Monday's attacks, some of which hit markets and crowded bus stops during the morning rush hour, have heightened fears that the country could be turning back down the path toward civil war.
Sectarian tensions have been worsening since Iraq's minority Sunnis began protesting what they say is mistreatment at the hands of the Shiite-led government. The mass demonstrations, which began in December, have largely been peaceful, but the number of attacks rose sharply after a deadly security crackdown on a Sunni protest camp in northern Iraq on April 23.
Iraq's Shiite majority, which was oppressed under the late dictator Saddam Hussein, now holds the levers of power in the country. Wishing to rebuild the nation rather than revert to open warfare, they have largely restrained their militias over the past five years or so as Sunni extremist groups such as al-Qaida have targeted them with occasional large-scale attacks.
But the renewed violence in both Shiite and Sunni areas since late last month has fueled concerns of a return to sectarian warfare. Monday marked the deadliest day in Iraq in more than 20 months, and raised the nationwide death toll since last Wednesday alone to more than 240 people, according to an AP count.
Prime Minister Nouri al-Maliki accused militant groups of trying to exploit Iraq's political instability to exacerbate sectarian tensions at home, and blamed the recent spike in violence on the wider unrest in the region, particularly in neighboring Syria. At the same time, he pledged Monday that insurgents "will not be able to bring back the atmosphere of the sectarian war."
Many Sunnis here contend that much of the country's current turmoil is rooted in decisions made by al-Maliki's government, saying his administration planted the seeds for more sectarian tension by becoming more aggressive toward Sunnis after the U.S. military withdrawal in December 2011.
The worst of Monday's violence took place in Baghdad, where 10 car bombs ripped through open-air markets and other areas of Shiite neighborhoods, killing at least 48 people and wounding more than 150, police officials said. In the bloodiest attack, a parked car bomb blew up in a busy market in the northern Shiite neighborhood of Shaab, killing 14 and wounding 24, police and health officials said.
The surge in bloodshed has exasperated Iraqis, who have lived for years with the fear and uncertainty bred of random violence.
"How long do we have to continue living like this, with all the lies from the government?" asked 23-year-old Baghdad resident Malik Ibrahim. "Whenever they say they have reached a solution, the bombings come back stronger than before."
"We're fed up with them and we can't tolerate this anymore," he added.
The predominantly Shiite city of Basra in southern Iraq was also hit Monday, with two car bombs there ? one outside a restaurant and another at the city's main bus station ? killing at least 13 and wounded 40, according to provincial police spokesman Col. Abdul-Karim al-Zaidi and the head of city's health directorate, Riadh Abdul-Amir.
A parked car bomb later struck Shiite worshippers as they were leaving a mosque in the southern city of Hillah, killing nine and wounding 26, according to police and health officials said.
In the town of Balad, about 80 kilometers (50 miles) north of Baghdad, a car bomb exploded next to a bus carrying Iranian pilgrims, killing 13 Iranians and one Iraqi, a police officer said on condition of anonymity because he was not authorized to brief the media.
There was no immediate claim of responsibility for the attacks, but the fact that they all occurred in Shiite areas raised the suspicion that Sunni militants were involved. Also, Sunni insurgents, particularly al-Qaida in Iraq, are known to employ such large-scale bombings.
Monday's violence also struck Sunni areas, hitting the city of Samarra north of Baghdad and the western province of Anbar, a Sunni stronghold and the birthplace of the protest movement.
A parked car bomb in Samarra went off near a gathering of pro-government Sunni militia who were waiting outside a military base to receive salaries, killing three and wounding 13, while in Anbar gunmen ambushed two police patrols near the town of Haditha, killing eight policemen, police and army officials said.
Also in Anbar, authorities found 13 bodies dumped in a remote desert area, officials said. The bodies, which included eight policemen who were kidnapped by gunmen on Friday, had been killed with a gunshot to the head.
The officials spoke on condition of anonymity because they were not authorized to talk to the media.

Associated Press writer Nabil Al-Jurani in Basra contributed to this report.
WASHINGTON (AP) ? A top White House adviser insisted Sunday that President Barack Obama learned the Internal Revenue Service had targeted tea party groups only "when it came out in the news" while Republicans continued to press the administration for more answers.
Trying to move past a challenging week that put the White House on the defensive, senior adviser Dan Pfeiffer was scheduled to appear on five Sunday news shows to repeat the administration's position that no senior officials were involved in the decision to give tea party groups extra scrutiny. Pfeiffer's appearances were unlike to quiet GOP critics, who have seized on the revelations as proof that Obama used the IRS to go after his political enemies.
"The deputy secretary of the treasury was made aware of just the fact that the investigation was beginning last year," Pfeiffer said. "But no one in the White House was aware."
Meanwhile, Sen. Rand Paul, R-Ky., suggested there was a written policy to target conservative groups opposing the president, but when pressed could not provide details.
"I haven't seen a policy statement, but I think we need to see that," Paul said. "And when that comes forward, we need to know who wrote the policy and who approved the policy."
Regardless of when the president first learned of the investigations, Pfeiffer said the president wanted to ensure such activities were not repeated.
"The activity was outrageous and inexcusable, and it was stopped and it needs to be fixed to ensure it never happens again," Pfeiffer said.
A Treasury Department inspector's report said this week that conservative and small-government tea party groups that were critical of Obama received extra scrutiny. IRS agents did not flag similar progressive or liberal groups, according to the watchdog.
The report concluded that a regional IRS office in Ohio improperly singled out tea party and other conservative groups for more than 18 months and took no action on many of their applications for tax-exempt status for long periods of time ? hindering their fundraising for the 2010 and 2012 elections.
The new acting IRS commissioner is in the midst of a 30-day top-to-bottom review while Republicans continue to demand answers of Obama and his allies in government.
That's not sufficient, said Sen. Rob Portman, R-Ohio.
"I think a special counsel is going to wind up being necessary," he added said.
That move is not needed, said Sen. Robert Menendez, D-N.J.
"I don't see the point," he said of a special counsel to investigate the scandal.
Rep. Tom Price, R-Ga., said the IRS had stepped so far over its mandate that it asked book groups for reading lists and church groups about their prayers before granting them tax-exempt standing. It's government over-reach, he said, and a reason why Republicans need to have their own investigation into the agency.
"This is about trust," Price said.
But he stopped short of calling for a special counsel.
Rep. Charlie Rangel, D-N.Y., said Republicans were using the incidents to embarrass the president.
"There is no Republican agenda other than to stop the president of the United States," he said.
Pfeiffer was appearing Sunday on ABC's "This Week," NBC's "Meet the Press," CBS' "Face the Nation," CNN's "State of the Union" and "Fox News Sunday." Portman, Menendez, Price and Rangel were on ABC. Paul was on CNN.
New plans available to existing customers now; new customers can take advantage June 6
As an update to a previous blog post detailing changes to its prepaid plans, Verizon stealthily made yet another change that will give prepaid customers even more data. Verizon keeps things simple on its prepaid smartphone offerings, with two tiers -- $60 and $70. Both have unlimited talk and text, and previously either 500MB or 2GB of data. Verizon is now bumping those up to 2GB and 4GB, respectively, with no price increase. The plan changes go into effect right away for existing customers that have either of the two plans, but new customers will have to wait until June 6th to have the option available when starting a line.
If you're new to Verizon's prepaid plans, you have to also remember that they are restricted to just its 3G service, and there's no indication of when (if ever) LTE will be included. With that being said, these are still a couple of good options that just got a little more competitive in the steadily expanding prepaid market.
LONDON (Reuters) - Britain's parliament will this week consider whether to probe the transparency of oil and mining firms listed in London, an issue highlighted by corruption probes at emerging market miners which lawmakers fear have dented the stock market's reputation.
The chairman of parliament's Committee for Business, Innovation and Skills said on Sunday he would this week propose an inquiry into issues including governance and anticorruption protection at mining and oil companies.
The probe could start before the end of the parliamentary session in July. The committee will, though, have to decide the specific terms of the inquiry.
Parliamentarian Adrian Bailey said those set to give evidence are expected to include executives from Kazakh miner ENRC and Indonesia-focused miner Bumi, both facing corruption probes that have hit already beleaguered shares. The banks that advised the two could also be called.
He said the committee had already been considering a look at the extractive industries but the current turmoil around ENRC - now facing a buyout bid from its founders that would take it private after just over five years - had given the inquiry "added significance".
"We will be looking at the issue of transparency in general. It is not an inquiry looking into just ENRC and Bumi," Bailey said, adding that the concerns raised by those two miners would, however, be central.
"We have not yet defined the focus of the inquiry, or indeed decided whether we are going ahead."
Parliamentary committees often bring political pressure to bear on companies by publishing reports and calling witnesses to evidence sessions. While their reports have no legislative weight, findings are aimed at influencing government policy.

Given the spotlight on London's reputation in recent months, the inquiry is widely expected to go ahead and could, among other things, look at the benefit of having major extractive companies listed in London.
It would also look at whether Britain should sign up to the Extractive Industries Transparency Initiative (EITI) as well as examining mining and oil companies' roles in communities and their environmental efforts.
The EITI, supported by the World Bank, was set up to improve transparency and accountability in countries rich in mineral resources.
Troubles at ENRC, the largest of the companies in question, have made it the focus of headlines and a fierce debate around foreign resources companies with majority owners. Boardroom battles and corruption probes have helped drag its share down more than 50 percent since the start of last year alone.
Indonesia-focused miner Bumi has been another listing troubled from the start. Corruption probes and a damaging shareholder battle between the founders - Indonesia's powerful Bakrie family and financier Nat Rothschild - have added to low coal prices, dragging the shares down almost 80 percent since its listing.
But Bumi and ENRC are only two of a clutch of foreign-owned resource companies that have listed in London in the past decade, transforming the once UK-focused bluechip FTSE index.
Scandals at both have overshadowed some of the successful listings, prompting questions over governance, the number of shares that should be required to be freely available for purchase and the role of willing bankers. The UK Listings Authority has proposed tighter entry rules, hoping to create a higher hurdle for companies wanting to access the London market.
The revised rules, on which it consulted with the market last year, could be published in the coming weeks.

DES MOINES, Iowa (AP) ? It's all about the odds, and one lone ticket in Florida has beaten them all by matching each of the numbers drawn for the highest Powerball jackpot in history at an estimated $590.5 million, lottery officials said Sunday.
The single winner was sold at a Publix supermarket in Zephyrhills, Fla., according to Florida Lottery executive Cindy O'Connell. She told The Associated Press by telephone that more details would be released later.
"This would be the sixth Florida Powerball winner and right now, it's the sole winner of the largest ever Powerball jackpot," O'Connell told AP. "We're delighted right now that we have the sole winner."
She said Florida has had more Powerball winners than any other state.
The winner was not immediately identified publicly and O'Connell did not give any indication just hours after Saturday's drawing whether anyone had already stepped forward with that winning ticket.
With four out of every five possible combinations of Powerball numbers in play, lottery executives said earlier that someone was almost certain to win the game's highest jackpot, a windfall of hundreds of millions of dollars ? and that's after taxes.
Saturday night's winning numbers were 10, 13, 14, 22 and 52, with a Powerball of 11.
Estimates had earlier put the jackpot at around $600 million. But Powerball's online site said early Sunday that its latest tabulations of all tickets sold put that jackpot at an estimated $590.5 million.
Terry Rich, CEO of the Iowa Lottery, initially confirmed that one Florida winning ticket had been sold. He told AP that following a winner, the Powerball grand prize was being reset at an estimated jackpot of $40 million, or about $25.1 million cash value.
The chances of winning the prize were astronomically low: 1 in 175.2 million. That's how many different ways you can combine the numbers when you play. But lottery officials estimated that about 80 percent of those possible combinations had been purchased recently.
While the odds are low for any one individual or individuals, O'Connell said, the chance that one hits paydirt is what makes Powerball an "exciting game to play."
"There is just the chance that you will have the opportunity and Florida is a huge Powerball state. We have had more winners than any other state that participates in Powerball."
Such longshot odds didn't deter people across Powerball-playing states ? 43 plus Washington, D.C., and the U.S. Virgin Islands ? from lining up at gas stations and convenience stores Saturday for their chance at striking it filthy rich.
Calls by AP to the Publix supermarket where the winning ticket was sold were not answered early Sunday.
Before the drawing, there was a rush for tickets around the country.
At a mini market in the heart of Los Angeles' Chinatown, employees broke the steady stream of customers into two lines: One for Powerball ticket buyers and one for everybody else. Some people appeared to be looking for a little karma.
"We've had two winners over $10 million here over the years, so people in the neighborhood think this is the lucky store," employee Gordon Chan said as he replenished a stack of lottery tickets on a counter.
The world's largest jackpot was a $656 million Mega Millions jackpot in March 2012. If $600 million, the jackpot would currently include a $376.9 million cash option.
Clyde Barrow, a public policy professor at the University of Massachusetts-Dartmouth, specializes in the gaming industry. He said one of the key factors behind the ticket-buying frenzy is the size of the jackpot ? people are interested in the easy investment.
"Even though the odds are very low, the investment is very small," he said. "Two dollars gets you a chance."
That may be why Ed McCuen has a Powerball habit that's as regular as clockwork. The 57-year-old electrical contractor from Savannah, Ga., buys one ticket a week, regardless of the possible loot. It's a habit he didn't alter Saturday.
"You've got one shot in a gazillion or whatever," McCuen said, tucking his ticket in his pocket as he left a local convenience store. "You can't win unless you buy a ticket. But whether you buy one or 10 or 20, it's insignificant."
Seema Sharma doesn't seem to think so. The newsstand employee in Manhattan's Penn Station purchased $80 worth of tickets for herself. She also was selling tickets all morning at a steady pace, instructing buyers where to stand if they wanted machine-picked tickets or to choose their own numbers.
"I work very hard ? too hard ? and I want to get the money so I can finally relax," she said. "You never know."

I am writing a program for my programming class and I seem to be having trouble with making sure the cells come to life correctly I think the issue is in my neighbor If statements but cant seem to find it. Here are the instructions my code and the text file
The game of life is a computer simulation of the life and death events of a population of organisms. This program will determine the life, death, and survival of bacteria from one generation to the next, assuming the starting grid of bacteria is generation zero (0). Each cell has a total of up to 8 neighbors, including the 4 immediately adjacent cells and the 4 diagonal cells. The rules for the creation of each cell in the next generation are as follows:
If the cell is currently empty: If the cell has exactly three living neighbors, it will come to life in the next generation. If the cell has any other number of living neighbors, it will remain empty. If the cell is currently living: If the cell has one or zero living neighbors, it will die of loneliness in the next generation. If the cell has four or more living neighbors, it will die of overcrowding in the next generation. If the cell has two or three neighbors, it will remain living. All births and deaths occur simultaneously (make sure you don't get this one wrong!).
line 100 if(life[row][col]== true && life[row+1][col]==true & row+1<20)//bottom
This should be && shouldn't it
line 139 is the same...
you have variables that you dont use as well.
Regards
Snoopy.

so i switched to for loops but I am not sure how to check the edge cells here is my new neighbor count code
int livecellNeighbors (bool life[SIZE][SIZE],int row,int col) { int neighbors=0; if (life[row][col]==true) { for (int i=-1; row+i<=row+1; i++) { for (int c=-1;col+c<=col+1;c++) { if (i==0 && c==0) { } else if (life[row+i][col+c]==true) neighbors++; } } } return neighbors; }
Adobe's Photoshop Express has been taking care of our botched photos on Android and iOS for quite some time, but it hasn't had its turn on a desktop-class platform. That changes with today's launch of a version for Windows 8 and RT. Like their mobile counterparts, Windows users can now make basic edits, apply filters and sync photos to Revel in a touch-friendly interface; the chief difference is the landscape-oriented Windows Store look. If you've wanted to use your Surface as a mobile photo workshop without paying for apps, you can grab Express for free at the source link.
