iPads Might Be Dangerous for the Faint-Hearted

Apple customers with heart conditions could find out that taking their iPads to bed with them may have consequences. The matter is that tiny magnets within the iPad cover can shut off implanted defibrillators on a pacemaker if you leave the device on your chest. The same may happen if you fall asleep with the iPad lying on you.

Of course, it doesn’t seem likely as a death scenario, but it is quite surprising that the geniuses at Apple didn’t think about people with heart conditions. Actually, even a 14-year-old girl could spot this, and she did. Gianna Chien made the discovery as part of her science fair project. However, her project didn’t get first place, maybe because the judges thought that Apple was perfect and iPads can’t harm anyone. But Chien will soon again be presenting her findings to 8,000 doctors at a meeting of the Heart Rhythm Society in Denver. Hopefully, she will find a more reasonable audience there.

The girl says that if you fall asleep with the iPad2 on your chest, the magnets in the cover can “accidentally turn off” the heart device. Since her dad is a doctor, she believes that it’s pretty important that people know this. Her study found that 30% of 

patients with defibrillators who put Apple devices on their chest were affected by iPads. Although most defibrillators can turn back on after the magnet is removed, some of them must be reactivated manually, which may causes a life-threatening situation.

According to John Day, head of heart-rhythm services at Intermountain Medical Center in Murray, Utah, and chairman of the panel responsible for reviewing scientific papers which will be presented at the Denver meeting, Gianna Chien’s research offers a valuable warning for patients with implanted defibrillators that deliver an electric shock to restart a stopped heart.

Should we let wunderkinds drop out of high school?

 
NEW YORK (AP) -- It's one thing to say tech geniuses don't need degrees. After all, Bill Gates, Steve Jobs and Mark Zuckerberg all dropped out of college.
But now we've got David Karp, who doesn't even have a high school diploma. Karp, 26, founded Tumblr, the online blogging forum, and sold it to Yahoo for $1.1 billion.
Which raises the question: When is it OK for a wunderkind to drop out of school?
Some folks in Silicon Valley and elsewhere say a conventional education can't possibly give kids with outsize talents what they need. Others, like Vivek Wadhwa, a fellow at Stanford Law School who teaches and advises startup companies, say dropping out to pursue a dream is like "buying a lottery ticket — that's how good your odds are here. More likely than not, you will become unemployed. For every success, there are 100,000 failures."
But what about kids who are so good at computer programming that schools can't teach them what they need to know? "That's what internships are for; that's what extracurricular activities are for," says Wadhwa, who has founded two companies.
Karp, in an interview with The Associated Press on Monday, said he hopes teenagers don't look at his success as an excuse for leaving school. "That is not a path that I would haphazardly recommend to kids out there," he said. "I was in a very unique position of knowing exactly what I wanted to do at a time when computer science education certainly wasn't that good in high school in New York City."
Karp's mother gave him the option of home-schooling when he was 14, after he completed his freshman year at the Bronx High School of Science, an elite New York City public school that only admits students who score well on a difficult entrance exam. Karp took Japanese classes and had a math tutor while continuing with an internship at an animation production company, but by age 16, he was working for a website and was on his way to become a tech entrepreneur. He never did get his diploma. Karp's mother told the AP that she let him leave school because she realized "he needed the time in the day in order to create."
That resonates with Penny Mills of Hudson, Mass., who let her son Thomas Sohmers, 17, drop out of 11th grade this year. "I could see how much of the work he was doing at school wasn't relevant to what he wanted to learn," she said. "He always wanted to learn more than what the schools wanted to teach him. At times it was very frustrating. I was fortunate to find people that were able to teach him more, but he has gone beyond what high school could ever give him."
Thomas has been working at a research lab at the esteemed Massachusetts Institute of Technology since he was 13, developing projects ranging from augmented reality eyewear to laser communications systems. He just won a Thiel Fellowship, which gives $100,000 to 20 people under the age of 20 each year so they can skip college to focus on research or a dream, whether it's a high-tech project, a business or a nonprofit. But his mom says she would have let him drop out even if he hadn't won the award.
"The part that really bothers me is that there are a lot of Thomases out there and their needs are not being met," said Mills.
Thomas says he's sad to be leaving his teenage friends behind, but he's excited about the future. And he has mixed feelings about his years in school. "I've had some amazing, great teachers that really have the passion to teach, but most of what is in school now is teaching to a test," he said. "It's really sad. You're not learning the skills for how to solve the problem — you are just learning the answer to this question that is going to be on the test."
Susan Bartell, a psychologist based in Port Washington, New York who works with adolescents and their families, says she frequently encounters parents who are convinced that their kids are extraordinarily gifted. But she cautions that it's "the very rare exception when this decision (to drop out) makes sense." In the case of Karp, she said, "it worked out, but almost always it doesn't — even if a kid is extremely gifted. School is about much more than just academics and in most cases, even the most gifted kids need the socializing."
And not all young moguls take Karp's route. Earlier this year, a 17-year-old from London, Nick D'Aloisio, sold an app he created to Yahoo for $30 million — but he decided to stay in school.
On the other hand, there are examples of successful individuals in many fields who lack a high school diploma, from top performers such as Jay-Z to billionaire businessmen such as Richard Branson.
The tech community may be different from other industries. Degrees are not necessarily seen as a hallmark of achievement and programmers are judged on their ability to type lines of code. You are what you create.
What also sets the field apart is that computer programming is not taught at every high school, and even when it is, the most talented students often either "surpass the curriculum or feel it's not relevant to them," said Danielle Strachman, program director for the Thiel Fellowship. "They want to move at their own pace."
Strachman also emphasized that just because someone has left school, doesn't mean they've stopped learning. The Thiel program provides not just funding, but a community of peers and mentors to help recipients reach their goals. And they can always go back to pursue a degree when the fellowship is over.
It's a goal that even Karp has his eye on— despite his newfound wealth. "I hope I have an opportunity to go to school at some point," he said, "and study something completely different."

Teen's invention could charge your phone in 20 seconds

Image of Eesha Khare
Waiting hours for a cellphone to charge may become a thing of the past, thanks to an 18-year-old high-school student's invention. She won a $50,000 prize Friday at an international science fair for creating an energy storage device that can be fully juiced in 20 to 30 seconds.
The fast-charging device is a so-called supercapacitor, a gizmo that can pack a lot of energy into a tiny space, charges quickly and holds its charge for a long time.
What's more, it can last for 10,000 charge-recharge cycles, compared with 1,000 cycles for conventional rechargeable batteries, according to Eesha Khare of Saratoga, Calif.
"My cellphone battery always dies," she told NBC News when asked what inspired her to work on the energy-storage technology. Supercapacitors also allowed her to focus on her interest in nanochemistry — "really working at the nanoscale to make significant advances in many different fields."
To date, she has used the supercapacitor to power a light-emitting diode, or LED. The invention's future is even brighter. She sees it fitting inside cellphones and the other portable electronic devices that are proliferating in today's world, freeing people and their gadgets for a longer time from reliance on electrical outlets.
"It is also flexible, so it can be used in rollup displays and clothing and fabric," Khare added. "It has a lot of different applications and advantages over batteries in that sense."

Hangouts Feature Emerges as a Big Bright Spot for Google+

 
Google still struggles to prove the value of its social network Google+; two years in, Time calls the project “tragic” and “perfunctory,” and the first question at a Google-sponsored “fireside chat” with developers was how to explain, as the questioner put it, “what it is” to users.
But there is, as the ongoing Google I/O developer conference in San Francisco makes clear, one unmitigated success for Google+: “Hangouts,” the video group chat feature introduced along with the rest of the social service two summers ago. Hangout has proven a topic of intense interest at I/O, packing in big crowds, and it’s clear listening to both the audience and presenters that the product is changing how people collaborate in educational settings as well as in certain workplaces, giving Google an impressive lead over rivals like Microsoft in an important and emerging new form of communication.
It’s no wonder that Google announced at this year’s I/O that it’s broadening the Hangouts brand beyond video chat, making it the basis of a new text, voice, and video chat layer intended to subsume disparate Google systems like GChat, Google Voice, and Google+ Messenger. But beyond the official corporate posturing and strategizing around Hangouts, there’s also an organic user story unfolding, which is to say: real people are using this thing in the real world to accomplish actual productive tasks, and they’re really liking it.
Online education is one obvious hotspot. An I/O session on “Online Learning with Google+” was packed as people jammed into a conference room at the Moscone West convention center to listen to stories from a two-person panel on how Hangouts use is evolving within education. The standing-room-only crowd listened intently as Coursera product engineer Pamela Fox ran through lessons her company has learned using Hangouts in conjunction with large online classes, including forming groups prior to gathering students in Hangouts for discussions, and having someone on hand within the chats to guide the conversation and restart it when a Hangout came to an awkward halt.
In a follow-up question and answer session, Fox fielded questions from a teacher, college administrator, and education startup. One member of the audience asked for further Hangouts-in-education tips at a Google+ “fireside chat,” and learned about how MIT has grappled with using Hangouts for the massive audience drawn to online courses offered by the university’s Media Lab. One common challenge: Coordinating student questions and answers through the app, for which one Google staffer recommended setting up a closed Google+ community.

Business types also queued up to ask about Hangouts, including one staffer from the popular online Q&A service StackOverflow, who said Hangouts are used extensively for company meetings but tend to mute background noise too aggressively, and another questioner who said the real-time chat tool “has been phenomenal for our business” but was confused about whether to use the new Hangouts mobile app or the Hangouts feature in the main Google+ app (use the Hangouts app, he was told).
Two years on, Google+ might be taking some licks in the press, as journalists fret over how the service can distinguish itself from competitors like Facebook and Twitter. But Hangouts already offers an easy, and readily corroborated, answer to that question.

The five ways Google is ‘assaulting’ Apple

 Google Vs Apple
Google CEO Larry Page spoke about peace in the industry during the Google I/O 2013 keynote, but that doesn’t mean Google has plans to slow its various attacks on rivals’ turf. Forbes contributor Peter Cohan laid out the five areas where Google is launching its “assault” on chief competitor Apple, and he discussed exactly how Google is hurting the world’s most valuable company in each area. Among Cohan’s five fronts are smartphones, where Google’s Android platform has overtaken the iPhone as the most popular handset operating system in the world; tablets, where strength in numbers will soon help Google top Apple’s market share once again; and innovation, the “most important front where Google is trouncing Apple.” Because the company is assaulting Apple on these five fronts and seemingly winning, Cohan says it looks like “Google is winning the war for the future.” Of course, whether or not this win will help Google top Apple’s record profits remains to be seen.

Steve Jobs’s Widow Debuts on Philanthropic Stage

Marlene Castro knew the tall blonde woman only as Laurene, her mentor. They met every few weeks in a rough Silicon Valley neighborhood the year that Ms. Castro was applying to college, and they e-mailed often, bonding over conversations about Ms. Castro’s difficult childhood. Without Laurene’s help, Ms. Castro said, she might not have become the first person in her family to graduate from college.
It was only later, when she was a freshman at University of California, Berkeley, that Ms. Castro read a news article and realized that Laurene was Silicon Valley royalty, the wife of Apple’s co-founder, Steven P. Jobs.
“I just became 10 times more appreciative of her humility and how humble she was in working with us in East Palo Alto,” Ms. Castro said.
The story, friends and colleagues say, is classic Laurene Powell Jobs. Famous because of her last name and fortune, she has always been private and publicity-averse. Her philanthropic work, especially on education causes like College Track, the college prep organization she helped found and through which she was Ms. Castro’s mentor, has been her priority and focus.
Now, less than two years after Mr. Jobs’s death, Ms. Powell Jobs is becoming somewhat less private. She has tiptoed into the public sphere, pushing her agenda in education as well as global conservation, nutrition and immigration policy. Just last month, for example, she sat down for a rare television interview, discussing the immigration bill before Congress. She has also taken on new issues, like gun control.
“She’s been mourning for a year and was grieving for five years before that,” said Larry Brilliant, president of the Skoll Global Threats Fund who is an old friend of Mr. Jobs. “Her life was about her family and Steve, but she is now emerging as a potent force on the world stage, and this is only the beginning.”
But she is doing it her way.
“It’s not about getting any public recognition for her giving, it’s to help touch and transform individual lives,” said Laura Arrillaga-Andreessen, a philanthropist and lecturer on philanthropy at Stanford who has been close friends with Ms. Powell Jobs for two decades. She is also the daughter of a wealthy real estate developer in Silicon Valley and the wife of Marc Andreessen, the venture capitalist.
“If you total up in your mind all of the philanthropic investments that Laurene has made that the public knows about,” she said, “that is probably a fraction of 1 percent of what she actually does, and that’s the most I can say.”
While some people said Ms. Powell Jobs should have started a foundation in Mr. Jobs’s name after his death, she did not, nor has she increased her public giving.
Instead, she has redoubled her commitment to Emerson Collective, the organization she formed about a decade ago to make grants and investments in education initiatives and, more recently, other areas.
“In the broadest sense, we want to use our knowledge and our network and our relationships to try to affect the greatest amount of good,” Ms. Powell Jobs said in one of a series of interviews with The New York Times.
Still, the fortune she inherited, making her the world’s ninth wealthiest woman, according to the Bloomberg billionaires index, has catapulted her into the upper echelon of global philanthropists. And that has led to certain expectations.
Ms. Powell Jobs has a net worth estimated at $11.5 billion, according to Bloomberg, most of it in shares of the Walt Disney Company. Mr. Jobs helped found the animation studio Pixar, which Disney acquired in 2006 and paid for in stock. With 131 million shares, worth about $8.7 billion, the Laurene Powell Jobs Trust is Disney’s largest shareholder with a 7.3 percent stake in the company, and she has benefited from the stock having more than doubled since her husband died in October 2011.
Mr. Jobs also owned 5.5 million shares of Apple at the time of his death, and it is unclear whether she has sold her position.
“She knows that she is in an unusual position and has the standing to have a major impact on the world stage,” said Peter Seligmann, chief executive of Conservation International, on whose board Ms. Powell Jobs sits. “It will be fascinating to watch the choices that she makes.”
Like many technology titans, her husband was criticized for not giving away as much money as he could. Mr. Jobs did not give publicly during his life — though there have been rumors of at least one major anonymous gift, to a hospital.
He also declined to sign the Giving Pledge, the organization started by Warren E. Buffett and Bill Gates to persuade the country’s richest families to vow to give away at least half of their fortunes. During the interview, Ms. Powell Jobs, who still wears her diamond wedding ring, would not discuss her husband or her children. And when asked if she would join the Giving Pledge, she demurred.
“Whether someone signs something is not what’s important,” said Ms. Powell Jobs. “It’s what they do and how they do it that matters.”
Ms. Powell Jobs, 49, grew up in West Milford, N.J., and earned an undergraduate degree from the University of Pennsylvania. She worked for three years at Goldman Sachs as a fixed-income trading strategist. Her boss was Jon Corzine, who would go on to run the firm and become governor of New Jersey. After Goldman, she attended Stanford Business School. In 1989, when Mr. Jobs visited the school to give a speech, he found himself seated next to her.
“I looked to my right, and there was a beautiful girl there, so we started chatting a bit while I was waiting to be introduced,” Mr. Jobs told Walter Isaacson, the author of the biography “Steve Jobs.”
They went out to dinner that evening, married two years later, and together had three children. Mr. Jobs died at 56 after a long battle with pancreatic cancer. Ms. Powell Jobs, a food lover, lives with her children in the same unpretentious red brick home she and Mr. Jobs bought two decades ago, where they raise bees and send friends Christmas baskets with hand-labeled Mason jars of honey.
Ms. Powell Jobs is best known in the education field for College Track, which she started in 1997. The group helps prepare low-income students from underserved communities for college, providing rigorous academic training and extracurricular activities. The program, which operates in a number of locations including East Palo Alto and New Orleans, has trained more than 1,400 students and sent 90 percent of them to college.
Last year, to be with her grieving family, Ms. Powell Jobs decreased her board seats to five from eight. But she also became a trustee at Stanford, which is near her home in Palo Alto.
Her involvement with immigration flowed from College Track. In its early years, a number of her students in the program were teenagers who had come to the country, unauthorized, at a young age and finished high school, but then could not obtain citizenship or receive any state or federal funds for college.
“This continues to be a purgatory that they find themselves in,” she said in an interview. “It is one of these issues that seems discordant with what our country stands for.”
Ms. Powell Jobs has become a leader in pushing for decade-old legislation known as the Dream Act, a measure that would provide legal status for immigrants who arrived in the country as young children. Last December, she enlisted the Academy Award-winning documentary filmmaker Davis Guggenheim to make a documentary about immigration. The two had met through their work in education; Mr. Guggenheim’s most recent film, “Waiting for Superman,” examined the crisis in America’s public schools.
“Laurene asked me how much time I needed to make a movie, and I told her about a year and a half,” Mr. Guggenheim said. “But she said that she needed something done in three months because the legislation was coming up for a vote.”
So instead of a creating a big feature with a broad theatrical release, Ms. Powell Jobs commissioned a 30-minute film, “The Dream Is Now,” which is viewable online and being shown at college campuses across the country. Last month, Ms. Powell Jobs and Mr. Guggenheim traveled to Washington with several young immigrants and their families who were featured in the film; the purpose of the trip was to screen the documentary for a group of lawmakers on Capitol Hill.
Ms. Powell Jobs said that while trying to make change in Washington can be frustrating, she remains devoted to her causes.
“Despite the setbacks and the sometimes obstreperous political processes, once we are committed to working in a field where we can help advance knowledge or more equal opportunity, we cannot quit,” Ms. Powell Jobs said. “I am so motivated by the stories of their students and their families, and I don’t give up because they don’t give up.”
Last December, Ms. Powell Jobs hired Russlyn H. Ali, who was assistant secretary for civil rights at the United States Education Department, to oversee education grants and investments at Emerson Collective. The name of the group pays homage to Emerson’s essay “Self-Reliance.”
Ms. Powell Jobs’s work is not limited to domestic issues. She has supported numerous causes in Africa, and has visited the continent several times. In 2010, she traveled to Congo with Ben Affleck and has provided support to his organization, the Eastern Congo Initiative. Last year, as a board member of Conservation International, she traveled to Botswana for a meeting of sub-Saharan Africa heads of state.
“She’s a very private person who might be more comfortable being in the back,” Mr. Seligmann said. “But she’s a smart, amazing communicator who is also very effective in the front.”

Comparisons to Dubya? Obama Planning Online Wiretapping Law

As you know, the British Labour Government will surely go down in history for its extensive use of CCTV cameras, but in the meanwhile, Barack Obama can become known for his online wiretapping laws.


ndaa+2013+big+brother.jpg


Media reports say that Barack Obama is going to end the long-running debate over online snooping with a legislation allowing law-enforcement agencies tapping into many types of online communications.

Everyone understands that bringing in this law will surely have political, technical and legal obstacles. Indeed, if Obama gets it through it would really represent a sea change in American culture. Industry experts point out that if he succeeds, the FBI and other agencies will have a right to snoop on voice-over-Internet-protocol (VoIP) services like Skype and real-time chats.

Apparently, it would end a regime where the FBI has difficultly snooping but is able to eavesdrop on traditional telephone calls. Of course, tech firms hate the idea, which would likely face stiff opposition in Congress. At the moment, spooks can ask the courts to wiretap almost anything, but only traditional telecommunications carriers are demanded to make it easy.

The law in question – Communications Assistance for Law Enforcement Act – doesn’t apply to any of Microsoft’s services, for example. This includes Skype, as it doesn’t class Microsoft as a traditional telecommunications carrier.

Thus, Obama’s new legislation would encompass VoIP, chat and any other online communication services. However, it is still unclear how tech companies could be compelled to help the authorities unscramble encrypted communications, apart from providing access. Actually, Obama’s proposed legislation is a slightly watered down version of what the Federal Bureau of Investigation wants. The FBI had called for a blanket requirement that ISPs provide authorized officials the same kind of sweeping, turn-key access to their networks that phone companies do.

However, tech firms, civil libertarians and some government officials claimed that it was impractical for smaller firms and such back doors can present serious security risks. Some of the critics insist that the fact the President would end up pushing the legislation will make him the punching bag for every American citizen who is already worried about their government.
