Mathway Android app calculates how to improve your math skills

APPOLICIOUS ADVISOR RATING:

4 of 5 bars PRICE: FreeTASTY: Solves math problems in a variety of categories.BUMMER: You must pay for a subscription before the app “shows its work.”COOL: App’s keyboard mimics that of a scientific calculator.

Your Android works hard to entertain you, but don’t let that be its only purpose. Use that powerful Android device as a bionic brain implant as well, and get smarter using it to calculate your work and teach you math at the same time.

The Mathway app delivers solutions to your math problems in a large set of categories, including basic math, pre-algebra, algebra, trigonometry, pre-calculus, calculus, and statistics.

The app starts by asking you to choose a category and then to simply enter the problem you’re working on. The keyboard for input shifts automatically from whatever you’re using – the standard Android keyboard or some other option – to Mathway’s own, which features all the keys of a scientific calculator. You’ll be able to input even a complex equation easily. Ask the app to solve it and it will crunch away to deliver the answer. If that’s all you need, you’re done. But if you want to learn the steps the app used to solve the problem you’ll need to upgrade your Mathway account with a day, month, or year-long subscription fee.

Samples from the premium account show you what you get and it looks pretty good for students or teachers leading a math class in elementary, junior high or high school. You can even drill deeper into each section of the how-to instructions for additional information.

What’s not to love? Well, with resources like khanacademy.org out there, the web sports a lot of math tutoring for free. Still, there aren’t many apps with this level of math help. Math instructors may not love this app because it can help students a little too much if misused, but hopefully, it will promote deeper understanding of math fundamentals.

Summary Box: Obama admin seeks privacy rules

THE VISION: The Obama administration is calling for stronger privacy protections for consumers who use the Internet, mobile phones and other technologies.

THE DETAILS: Technology companies, consumer groups and others will now convene to jointly craft new protections. Such guidelines will initially be voluntary for companies, but those that agree to abide by them could be subject to sanctions for any violations.

THE REACTION: Consumer and privacy groups welcomed the effort, though some worried that it won't do enough. Legislation would be needed to require all companies to follow such guidelines.

OmniVision 3Q profit and 4Q outlook beat estimates

SANTA CLARA, Calif. (AP) — Image sensor maker OmniVision Technologies Inc. posted a sharp drop in its fiscal third-quarter profit on Thursday due to lower sales, lower prices, and greater operating expenses.

However, its revenue surpassed Wall Street estimates, and the company also forecast a better-than-expected fourth quarter. Its shares jumped $1.97, or 12 percent, to $18.05 in aftermarket trading.

Over the three months ended Jan. 31, OmniVision said its profit fell to $111,000 from $44.7 million. The company broke even on a per-share basis after reporting a profit of 75 cents per share a year ago.

OmniVision said it earned 13 cents per share if stock-based compensation and related costs are excluded. Revenue sank 30 percent, to $185.2 million from $265.7 million.

Analysts expected the company to report an adjusted profit of 13 cents per share on $176.6 million in revenue, according to FactSet.

OmniVision said its profit margins fell because of lower average sales prices and greater inventory costs. Its operating expenses grew to $44.4 million from $38.6 million.

The company said it expects to report an adjusted profit of 15 to 28 cents per share in the fourth quarter on revenue of $195 million to $215 million. That represents a decreased of 17 to 25 percent from the $258.3 million it reported in the fourth quarter of fiscal 2011.

Analysts were forecasting a fiscal fourth-quarter profit of 10 cents per share and revenue of $169.8 million on average.

OmniVision Technologies shares rose 2 cents to $16.08 during Thursday's regular trading session. The stock is still well below its peak of $37.05 touched in late May.

Eastern Europeans fuel fight for Internet freedoms

WARSAW, Poland (AP) — Eastern Europe's tradition of political revolt has met the digital age. This time it's not communists or food shortages fueling fury, but an international copyright treaty that opponents say threatens freedom on the Internet.

A grassroots protest movement erupted last month in Poland and spread quickly across the former Eastern Bloc and beyond. The growing opposition against the Anti-Counterfeiting Trade Agreement, or ACTA, has raised questions about the fate of the treaty, which is important to the governments of the United States and other industrialized economies.

There have been street protests across Eastern Europe, attacks on government websites in the Czech Republic and Poland, even a heartfelt apology from a Slovenian ambassador who signed it and then decried her act as "civic carelessness."

In a region where people remember being spied upon and controlled by oppressive communist regimes, the treaty has provoked fears of a new surveillance regime.

The pact aims to fight intellectual property theft — like fake Gucci handbags and violations of pharmaceutical patents. But it also targets online piracy — illegal downloads of music, films and software — and calls for measures that critics say would bring surveillance of Internet users.

"Most of the people who have gone to the streets are young and don't remember communism themselves, but Polish society as an entity remembers," said Jaroslaw Lipszyc, the president of the Modern Poland Foundation, an organization devoted to education and developing an information society.

"In Poland freedom of speech is of special value, and there is a history of fighting for it."

Lipszyc, a prominent ACTA opponent, sees his work today as a natural extension of the same struggle for free expression that prompted his own family to illegally print anti-communist essays in their basement during the 1980s.

Eastern European countries, even those now in the European Union, are still much poorer than the West, and among critics are people who fear losing access to free — sometimes illegal — entertainment. With joblessness in Poland at 12.5 percent and the monthly minimum wage at just 1,500 zlotys ($465) pre-tax and average wages at 3,605 zlotys ($1,130), many say they can't afford 20 zlotys ($6.30) or more for a movie ticket.

"People became furious," said Katarzyna Szymielewicz, director of Poland's Panoptykon Foundation, which campaigns for privacy rights in a context of modern surveillance and opposes ACTA. "We have a history of rising up against injustice."

ACTA went from being an obscure international agreement to a household term in Poland in mid-January when the government said it would sign it within days. Civil rights organizations like Panoptykon were outraged because the government failed to consult with them first.

Szymielewicz said they got word out on Twitter and other social forums, and soon Internet activists in Poland and abroad — some with the group "Anonymous" — waged attacks on government websites, including those of the prime minister and parliament, leaving some unreachable for days.

The anger drew on a broader frustration in society, especially among youth, over a lack of jobs and a sense of alienation from the political process.

"This was the last drop that made it a flood," Szymielewicz said. "The Internet is a space of freedom — something people feel really belongs to them — and suddenly the government interferes with this space."

Poles and others were also primed to act because many had been following the opposition in the United States to two similar initiatives, the Stop Online Piracy Act and Protect Intellectual Property Act — known popularly as SOPA and PIPA. American lawmakers shelved those bills after massive pressure that included a one-day blackout by Wikipedia and other Web giants.

Days later, Poles took to the streets across the country against ACTA — activism that spread to Berlin, Sofia, Bucharest and many other cities where thousands rallied last Saturday. More rallies are planned for Feb. 25.

Opponents are also angry that the treaty was negotiated for almost four years in secret without input from civic rights groups, giving them the impression that it is a backroom deal made on behalf of powerful industries.

The United States and other proponents of ACTA deny that it will be invasive. They argue that protecting intellectual property rights is needed to preserve jobs in innovative and creative industries. The online piracy of movies and music costs U.S. companies billions of dollars every year.

Washington also vows that individuals would not be monitored online and that ACTA would instead target companies that profit from using pirated products like software.

"Civil liberties would not be curtailed," says the Office of the U.S. Trade Representative, which signed ACTA in October.

But opponents say the agreement is worded so vaguely that it is unclear what would be legal and what not. Some people fear they could be prosecuted for, say, mixing home video footage with a Lady Gaga song and putting it on YouTube to share with friends.

"Because it's unclear what is allowed, people will limit their creativity," said Anna Mazgal, a 32-year-old Polish civil rights activist. "People could censor themselves out of fear because it's so vague."

Many opponents also fault ACTA for putting commercial values like profit above rights like freedom of expression.

"It's not surprising that European citizens are taking to the streets in the thousands to protest against an agreement that puts rightsholders' private economic interests ahead of their fundamental rights," said Gwen Hinze, the international intellectual property director with the Electronic Frontier Foundation, a San Francisco-based group that defends civil liberties on the Internet.

All the uproar has put ACTA's supporters on the defensive, at least for now.

The agreement has already been signed by the United States, Japan, South Korea and about 20 other countries.

But some governments which have signed it now say they won't ratify it, including Poland, Slovenia and Bulgaria. The Czech Republic says it needs to analyze the matter before deciding. A key test will come in the summer when the European Parliament will vote on it.

Germany says it supports ACTA as a way of defending intellectual property rights, but has promised to clarify doubts about it before signing it. Thousands protested last Saturday against ACTA across Germany, where data protection has long been a widespread concern and officials have clashed with Internet giants such as Google and Facebook over privacy issues.

The Slovenian ambassador to Japan, who signed it in Tokyo last month on behalf of her nation, later apologized, saying she had not understood at the time how it could limit freedom "on the most significant network in human history."

"I signed ACTA out of civic carelessness," Helena Drnovsek Zorko wrote on her blog.

Apple ponders cash, caves on board-vote proposal

CUPERTINO, California (Reuters) - Apple Inc on Thursday adopted a measure long desired by investors and corporate governance activists, granting its shareholders a bigger say in the appointment of directors to the board of the world's most valuable technology company.

Chief Executive Tim Cook also repeated that he has been "thinking very deeply" about investors' demands that the consumer electronics company return some of its $98 billion in cash and securities to shareholders via a dividend.

Wall Street has bet on the rising likelihood that some of that enormous war chest could be doled out this year, since Cook told investors last week that discussions around that hoard had intensified.

"We've been thinking about cash very deeply," he said, echoing previous comments. "Frankly speaking, it's more than we need to run the company."

At its annual shareholders meeting in Cupertino, Apple finally acceded to demands from U.S. pension fund Calpers and other major investors that it require unopposed directors to secure a majority-share vote before getting elected to the board.

That move came after shareholders last year, in a rare show of activism for a group often content with the iPad and iPhone maker's sizzling growth and lofty share price, voted in favor of a similar proposal - despite Apple's recommendation they reject it.

Apple General Counsel Bruce Sewell said the company had previously resisted the change because it creates legal complications. "But this is Apple and we don't let complexity get in our way," he said.

The proposal's adoption predictably pleased Calpers, the largest U.S. pension fund that has long sought support for such a measure to be adopted at scores of other U.S. corporations.

Speaking to shareholders and executives, Calpers portfolio manager Anne Simpson invoked the words of former British Prime Minister Winston Churchill.

"We think Apple deserves the best, we want to keep Apple fresh," she said. "Democracy is a wonderful thing. Despite its complexity and challenges, as Churchill said, it may be the worst of all systems until you consider the alternatives."

Apple said directors who do not manage to secure a majority vote will voluntarily resign their positions.

The meeting comes days after Apple touched a lifetime high of $526.29, cementing its ranking as the most valuable U.S. company with over $450 billion in market capitalization.

Some analysts say the stock may even scale new heights next month, when the company is expected to unveil a new version of its best-selling iPad.

FROM TVS TO CHINA

Apple's yearly powwows with shareholders at 1 Infinite Loop are generally contention-free affairs, with executives mostly deflecting questions about upcoming products - whose new features are guarded fiercely.

One shareholder nonetheless tried to find a way around executives' wall of silence about its pipeline, including an Apple TV rumored for 2012 that could mark its entree into a television business now dominated by Samsung Electronics.

"I just bought a 55-inch LG TV for the Superbowl and I have 60 days to return it. Should I return it?" one shareholder asked as laughter erupted. Cook declined to comment.

Away from its gadgets and bottom line, Cook continues to grapple with negative publicity surrounding accusations of inhumane working conditions at the company's manufacturing partners in China.

A handful of protesters gathered outside the meeting, holding up small placards urging Apple to make an "ethical" iPhone. The company has been trying to direct the spotlight on its efforts to urge partners to treat their employees better.

Recent moves include inviting independent scrutiny of conditions at its biggest production partner Foxconn in southern China, where a rash of worker suicides put Apple's supply chain under a microscope.

It also unveiled the results of labor audits at over 100 of its suppliers and allowed TV cameras onto Foxconn's closely guarded facilities.

No shareholder broached allegations of labor abuse in China at Thursday's meeting but some said afterward they wanted Apple to improve the treatment of workers in its supply chain.

"With all that money, maybe we could minimize the exploitation of some of the labor force. I'd kick in an extra dollar to buy an iPod or $5 to buy an iPad if it meant somebody somewhere down the road wasn't being exploited," said retired airforce pilot Eric Schwalm as he left the meeting.

Summary Box: T-Mobile subs down, iPhone to blame

SUBSCRIBER DROP: Customers have been leaving T-Mobile USA, the country's No. 4 cellphone company, for the last two years. Now that all three of the bigger carriers have the iPhone, that stream has turned into a flood.

THE NUMBERS: It lost a net 526,000 subscribers in the fourth quarter. Worse, it lost a net 802,000 subscribers on contract-based plans, which are the most lucrative.

IN PERSPECTIVE: T-Mobile is now losing subscribers from contract-based plans faster than regular phone companies are losing landline customers.

White House privacy push seeks cooperation

WASHINGTON (Reuters) - The White House proposed on Thursday a "privacy bill of rights" that would give consumers more control over their data but relies heavily for now on voluntary commitments by Internet companies like Google Inc and Facebook.

The plan comes amid growing consumer concern about their lack of control over the collection and trade in vast amounts of detailed information about their online activities and real-life identities.

As part of the announcement, an online advertising coalition associated with Google Inc, Yahoo Inc and Microsoft Corp said its members agreed to placing "Do Not Track" technology in Web browsers, something the Federal Trade Commission has been advocating since 2010.

But privacy advocates said that commitment was of limited scope and consumers should avoid thinking their Internet activity would be totally shielded.

Various federal agencies, including the FTC and Department of Commerce, have recommended similar privacy rights in the past, but broad legislation has failed to get traction. Privacy laws have been narrowly tailored toward protecting children, or categories of data such as credit reports and health records.

Legislators and privacy advocates said they hoped the White House call for talks with Internet companies, consumer groups and other stakeholders would lead to voluntary adoption of strong protections, which would undercut industry lobbying against legislation in a divided Congress.

"The hope would be that this is a measure that you get all the large advertisers to agree to. Then it gets to be in their interest to get it enforced on the others through legislation," said Christopher Calabrese, lobbyist for the American Civil Liberties Union.

A leading Republican on the issue in the GOP-controlled House, Representative Mary Bono Mack, gave tepid support, saying she would work with the administration but that "any rush-to-judgment could have a chilling effect on our economy and potentially damage, if not cripple, online innovation."

The White House proposed seven basic protections that consumers should expect from companies.

Consumers should have control over the kind of data companies collect, companies must be transparent about data usage plans and respect the context in which it is provided and disclosed. Companies would have to ensure secure and responsible handling of the data and be accountable for strong privacy measures.

The bill of rights also calls for reasonable limits on the personal data that online companies can try to collect and retain, and the ability for consumers to correct their information.

TARGETED AD PROTECTION

The White House said an existing industry-backed system for giving consumers the ability to avoid targeted online ads, that companies can charge more for, had been strengthened.

Microsoft's Internet Explorer and Mozilla's Firefox already allow consumers to indicate that they do not want to be tracked as they surf the Web, but advertisers can ignore those requests. Google said on Thursday that it would add a "Do not track" button to its Chrome browser.

The Digital Advertising Alliance, a self-regulatory body representing media and marketing trade associations said its members would honor consumer requests and it would work with browser companies to give consumers preference tools.

Stu Ingis, the group's general counsel, said he expected within nine months for browsers to include a simple, clear mechanism for consumers to opt-out of data collection.

That opt-out would not end tracking, privacy advocates said.

"It's a bogus sham," said John M. Simpson, privacy director at Consumer Watchdog. "All it does is that advertisers stop serving you targeted ads, but they continue to track. It doesn't go far enough."

Consumers might still receive ads aimed at small groups of people, said Fred Cate, an Indiana University professor and former FTC adviser. And companies would be free to use what they know about individuals for market research and to tailor their products.

Obama's announcement comes as he hones his strategy for winning re-election in November.

"American consumers can't wait any longer for clear rules of the road that ensure their personal information is safe online," President Barack Obama said in a statement.

"As the Internet evolves, consumer trust is essential for the continued growth of the digital economy. That's why an online privacy Bill of Rights is so important."

WORKING WITH INDUSTRY

The Commerce Department now will work with companies and privacy advocates to develop "enforceable" privacy policies based on the bill of rights, said the White House.

FTC Chairman Jon Leibowitz said a failure to meet privacy commitments, once adopted, could be a deceptive act or practice, warranting FTC fines or other action.

Internet companies have tried to get ahead of reforms by adopting privacy policies, but have still come under fire from Congress and consumer groups.

In the latest flare-up, a group of 36 state attorneys general sent a letter to Google on Wednesday with concerns about the search giant's plans to begin sharing users' personal information across Google products on March 1 without giving consumers an opt-in option.

"It rings hollow to call their ability to exit the Google products ecosystem a 'choice' in an Internet economy where the clear majority of all Internet users use - and frequently rely on - at least one Google product on a regular basis," the National Association of Attorneys General said in the letter.

Google said it viewed targeted ads and other Internet features that allow users to personalize their Web experience as a good thing. But consumers need choice through product controls that are easy to use, the company's senior vice president of advertising Susan Wojcicki said in a blog post.

Facebook's chief privacy officer-policy, Erin Egan, said the social networking site looked forward to helping develop enforceable codes of conduct that would balance "the public's demand for new ways to interact and share."

Marc Rotenberg, executive director of the Electronic Privacy Information Center, called Obama's privacy rights statement "the clearest articulation of the right to privacy by a U.S. president in history.

"But there are real concerns about implementation and enforcement," he added.
