Pandora’s 48 million users tune in an average 11.6 hours a month. That could increase as Pandora strikes deals with the makers of cars, televisions and stereos

At the end of 2009, Pandora reported its first profitable quarter and $50 million in annual revenue — mostly from ads and the rest from subscriptions and payments from iTunes and Amazon.com when people buy music.

Its library now has 700,000 songs, each categorized by an employee based on 400 musical attributes, like whether the voice is breathy, like Charlotte Gainsbourg, or gravelly like Tom Waits.

Chinese Premier Li Keqiang finished his four country tour of Africa, making stops in Ethiopia (including the African Union headquarters), Nigeria, Angola, and Kenya. China’s activities in Africa are increasingly gaining media attention around the world, particularly as speculation heats up about a competition for the continent between China and the U.S. (or even China and Japan).

Li promised to devote “more than half of its foreign aid to Africa,” with no conditions attached to the funding. Li pledged China’s friendship to Africa, and reiterated Chinese support for Africa playing a larger role in world politics as it continues to develop. Li also stressed that China “will never attach political conditions to its assistance to Africa and will never use its aid programs to interfere in the internal affairs of African countries,” a tacit criticism of Western countries who often refuse to provide funding to countries seen as human rights violators.

Li Keqiang also acknowledged in a speech that China-Africa relations have encountered some “growing pains,” a nod to tensions in some African countries over issues such as illegal Chinese mining operations and resentment against local Chinese traders. But Xinhua was quick to emphasize that these “growing pains” are “problems that inevitably occur during the development of relations” — meaning no one (especially not China) is to blame.

BERLIN — The European Commission is planning a legal change next year that may prompt U.S. Web giants like Google and Facebook to rethink how they store and process consumer data, raising the prospect of a trans-Atlantic dispute over Internet privacy.

The European law gives individuals more control over the use of data they enter on free Web services, but it has not been revised since 1995, when the Internet was still in its infancy.

Facebook and Google have signed the Safe Harbor Agreement, a 2000 pact between the United States and the European Union under which U.S. signatories promise to handle the data of European citizens according to E.U. rules.

But it took a long time for solar sails to go from concept to reality. The first successful demonstration of the propulsion system didn't come until 2010, when Japan's Ikaros probe deployed its 46-foot-wide (14 m) sail and became the first craft ever to cruise through space on the backs of photons.

The $27 million Sunjammer mission, which takes its name from the Arthur C. Clarke story, will use a sail built by California-based company L'Garde that measures 124 feet (38 m) on a side. The sail, made of an advanced material called Kapton, is just 5 microns (about 0.0002 inches) thick. It weighs less than 70 pounds (32 kilograms) and packs down to the size of a dishwasher, NASA officials have said.

Closer to home, private industries like Mars One seek to establish a permanent settlement on the Red Planet. At the Smithsonian Magazine's "The Future is Here Festival" in Washington, D.C. this month, former astronaut Mae Jemison and NASA engineer Adam Steltzner spoke optimistically about the future of manned space exploration

Although the idea that bacteria — and life — could hitch a ride on traveling rocks to spread life to other planets is not new, Steltzner suggested a deliberate program that sounds more like science fiction than science fact. Such bacteria could carry our genome and the instructions to reassemble it after landing on a planet (and, one assumes, after the planet has been terraformed to support such life). Steltzner described the process as "printing human beings organically over time."

In addition to curiosity-motivated exploration, Steltzner pointed out that as long as humans remain on a single planet, we are at risk of extinction when disaster strikes. "Our real estate portfolio suffers from a concentration of risk," he said.

By Samuel Greengard Communications of the ACM, Vol. 52 No. 7, Pages 18-19 10.1145/1538788.1538796 Comments (3) View as: Print ACM Digital Library Full Text (PDF) In the Digital Edition Share: Send by email Share on reddit Share on StumbleUpon Share on Tweeter Share on Facebook More Sharing ServicesShare Society has long cherished the ability to think beyond the ordinary. In a world where knowledge is revered and innovation equals progress, those able to bring forth greater insight and understanding are destined to make their mark and blaze a trail to greater enlightenment. "Critical thinking as an attitude is embedded in Western culture. There is a belief that argument is the way to finding truth," observes Adrian West, research director at the Edward de Bono Foundation U.K., and a former computer science lecturer at the University of Manchester. "Developing our abilities to think more clearly, richly, fully—individually and collectively—is absolutely crucial [to solving world problems]." To be sure, history is filled with tales of remarkable thinkers who have defined and redefined our world views: Sir Isaac Newton discovering gravity; Voltaire altering perceptions about society and religious dogma; and Albert Einstein redefining the view of the universe. But in an age of computers, video games, and the Internet, there's a growing question about how technology is changing critical thinking and whether society benefits from it. Although there's little debate that computer technology complements—and often enhances—the human mind in the quest to store information and process an ever-growing tangle of bits and bytes, there's increasing concern that the same technology is changing the way we approach complex problems and conundrums, and making it more difficult to really think. "We're exposed to [greater amounts of] poor yet charismatic thinking, the fads of intellectual fashion, opinion, and mere assertion," says West. "The wealth of communications and information can easily overwhelm our reasoning abilities." What's more, it's ironic that ever-growing piles of data and information do not equate to greater knowledge and better decision-making. What's remarkable, West says, is just "how little this has affected the quality of our thinking." According to the National Endowment for the Arts, literary reading declined 10 percentage points from 1982 to 2002 and the rate of decline is accelerating. Many, including Patricia Greenfield, a UCLA distinguished professor of psychology and director of the Children's Digital Media Center, Los Angeles, believe that a greater focus on visual media exacts a toll. "A drop-off in reading has possibly contributed to a decline in critical thinking," she says. "There is a greater emphasis on real-time media and multitasking rather than focusing on a single thing." Nevertheless, the verdict isn't in and a definitive answer about how technology affects critical thinking is not yet available. Instead, critical thinking lands in a mushy swamp somewhere between perception and reality; measurable and incomprehensible. It's largely a product of our own invention—and a subjective one at that. And although technology alters the way we see, hear, and assimilate our world—the act of thinking remains decidedly human. Back to Top Rethinking Thinking Arriving at a clear definition for critical thinking is a bit tricky. Wikipedia describes it as "purposeful and reflective judgment about what to believe or what to do in response to observations, experience, verbal or written expressions, or arguments." Overlay technology and that's where things get complex. "We can do the same critical-reasoning operations without technology as we can with it—just at different speeds and with different ease," West says. What's more, while it's tempting to view computers, video games, and the Internet in a monolithic good or bad way, the reality is that they may be both good and bad, and different technologies, systems, and uses yield entirely different results. For example, a computer game may promote critical thinking or diminish it. Reading on the Internet may ratchet up one's ability to analyze while chasing an endless array of hyperlinks may undercut deeper thought.

In the Ideal to Real TODAY/AOL Body Image survey, teenage girls revealed something unexpected: 65 percent said seeing their selfies on social media actually boosts their confidence. And 40 percent of all teens say social media helps "me present my best face to the world." 

Selfies seem inconsequential or goofy, but they can actually be incredibly important to teenagers, because they give teens a way to control the image of themselves that they’re showing to the world, experts say.

Still, for all that's empowering about selfies, teens — especially young women — naturally have mixed feelings about them. As long as young people are in control of the image, they are confident. But, in the TODAY/AOL body image survey, they acknowledge social media's power to make them feel bad about themselves, especially when confronted with glamorous, mostly happy, pictures of other people's lives.

Tags help you find and organize your bookmarks by letting you select all of your bookmarks with a certain tag or combination of tags. Quickly add relevant tags to a bookmark by clicking on any of the recommended tags that appear under the description field on the “Save Bookmark” pop-up. When you are satisfied with the information in the “Save Bookmark” pop-up, click the “Save Bookmark” button. Now a link to the page is stored in your Diigo library, and the information you entered is stored with it.

Highlight Highlighting lets you denote important information on a page, just like highlighting in a book, but with Diigo, the highlighted text will be conveniently saved to your library as well. There are some important things for me to denote on my recipe. My wife doesn’t like pineapple, my grandfather can’t have eggs or chocolate, and I don’t like coconut very much, so I highlight those items on the recipe to let me know I need to deal with them. Highlight by clicking “Highlight” on the Diigolet. Then select the text you want to highlight. The text will be visually highlighted and the text is now stored in your library. It’s that easy. Click the button again to exit highlighter mode. You can also change the color of a highlight by clicking the downward-pointing arrow next to “Highlight” and choosing a color. Colors are useful for differentiating different types of highlights. I will use a different color for each of the different people I need to consider.

To add a sticky note to a highlight, simply move your mouse cursor over a highlight. When the little pop-up tab with the pencil on it appears, move the cursor to it and a menu will appear. Choose “Add Sticky Notes”. Now you can type and post a sticky note just like before, but this time it will be tied to the highlighted text.

 Feature Highlight: Highlights Diigo saves the day with "highlights". Highlights let you select the important snippets on a page and store them in your library with the page's bookmark. Let's try it. Just open a page, maybe one of your old-school bookmarks or one of your new cat bookmarks, and find the information on that page you actually care about. Select that important text. Got it? Okay, now put your hemet on, 'cause this might blow your mind! Click the highlight icon on the Diigo toolbar. It's the one with the "T" on a page with a yellow highlighter. You will notice that the selected text gets a yellow background. This means that the text has been saved in your library, and as long as you have the Diigo add-on the text will be highlighted on the page! How's that for easy?   Now you've highlighted the text. It will appear in your library within the bookmark for the page it is on. Go to your library and you can see how it works. If you're not sure how to get to your library, just click the second icon on the toolbar (Diigo icon to the left of the search bar) and then select "My Library »".

Sticky Notes on the Web What? I can put a sticky note on a web page? How? Oh, that's right! Diigo. Just right-click anywhere on the page and choose to "add a floating sticky note". Type up your note and choose "Post", then move the note anywhere on the page. You have to type a note first, before you move it where you want, otherwise there's nothing to move!

Big, though, because the closure makes Netflix the latest of the big tech companies and services to have restricted their APIs. Twitter has done it. So has Amazon. So has Google.

APIs are enablers of remix culture, essentially. And what they mix is structured data.

Because of all that, APIs have been seen, traditionally, as symbolic and practical.

Within these contexts, the act of arranging objects, images or sounds into an order that may or may not have meaning has proliferated throughout the creative and cultural industries. The curator is now a producer: you might curate your Flickr feed, your mates playing records at a bar or an exhibition in your own apartment – a trend showcased by the Serpentine Gallery's co-director Hans Ulrich Obrist, a master orator of what he calls a "global dialogue… in space and time".

A space has now opened up – both physically and online – where anyone can give curating a go.

What, then, if we're looking in the wrong place for qualified, ground-breaking curators? Perhaps they are no longer in museums, galleries or cultural institutions, but instead in front of a screen – sociable and connected. Curating in the age of the internet is the act of responding to social and technological developments: their usability, instability and the various networks of communication in which they are presented online.

t’s a truism that Facebook is the many-headed frenemy, the great underminer. We know this because science tells us so. The Human–Computer Institute at Carnegie Mellon has found that your “passive consumption” of your friends’ feeds and your own “broadcasts to wider audiences” on Facebook correlate with feelings of loneliness and even depression

Even the positive effects of Facebook can be double-edged: Viewing your profile can increase your self-esteem, but it also lowers your ability to ace a serial subtraction task.

A closer look at Facebook studies also supports an untested but tantalizing hypothesis: that, despite all the evidence, Facebook is actually not the greatest underminer at the social-media cocktail party (that you probably weren’t invited to, but you saw the pictures and it looked incredible). Facebook is not the frenemy with the most heads. That title, in fact, goes to Instagram

Pandora continues to grow with 250 million registered users

There are one billion FM radios in the US and 160 million smartphones and 160 million PCs, so it’s still a subset of the FM marketplace.

Pittman doesn’t believe streaming hours will overtake traditional radio in his lifetime.

The Internet has become an essential propagator of knowledge, both through free as well as paid services. The credibility of this form of education and whether it is safe, secure, and trustworthy, is usually proven through the quality and authenticity of content presented by each website. The World Wide Web has become a remarkable avenue for the academically unprivileged, to amass greater knowledge and know-how on subjects.

The World Wide Web has become a remarkable avenue for the academically unprivileged, to amass greater knowledge and know-how on subjects. The entire scope of homeschooling has expanded because of increased accessibility to videos of teachers giving lectures, showing diagrams and explaining concepts, much like a real classroom. Nonprofit organizations too have opened websites that seek volunteers and donations in order to help the ones in need. There are also sites like Wikipedia, Coursera, Babbel, Archive, and Teachertube, among others, that have dedicated themselves to the art of imparting knowledge to people of all age groups.

About 99% of U.S. households (the total of which are in the 115 million range) have a TV, and 56% have cable. Compare that to Netflix, which has more than 48 million members worldwide. That means its entire global viewership is still not even half the U.S. However, that's not bad for a company founded in 1997, tackling a nearly 64-year-old industry.

In the summer months, it's easy to assume Netflix usage would go through the roof, thanks in part to younger students who now have three free months of time.

While Netflix doesn't share specific data on its viewers, spokeswoman Jenny McCabe said the site doesn't acquire more subscribers during the summer months. Rather, it picks up more viewers in Q1 (January, February and March) and Q4 (October, November and December).
