Study: Youâve Never Met 7% Of Your Facebook âFriendsâ

Source: http://techcrunch.com/2011/06/16/study-youve-never-met-7-of-your-facebook-friends/

A just-released Pew study on the ways people use social networking sites has found, unsurprisingly, that the most popular social network is Facebook, with 92% of social networking users reporting that they have a Facebook account.

The study also found that on average Facebook users have about 229 Friends, with about 22% of their total Friends list being comprised of people they know from high school, 12% extended family, 10% coworkers, 9% college friends, 8% immediate family, 7% people from extracurricular groups and 2% being neighbors.

According to Pew, the average Facebook user has never met 7% of their Facebook “Friends” in real life, which means that on average about 16 people on a given Facebook Friends list are actually more like strangers. Users on average have only met 3% of their list (around 7 people) just once.

These numbers seem about right: A quick scroll down my Facebook Friends list reveals a smattering of people I’ve just added because I know “of” them and a few people I’ve added who I’ve met once at a conference. These not-quite friends Facebook Friends serve as reminders that Facebook should make it easier to mass “un-Friend.”

Either that or come up with a different word for the relationship.

Brain Workshop Is a Brain-Training App That Might Actually Make You a Little Bit Smarter [Video]

Brain Workshop Is a Brain-Training App That Might Actually Make You a Little Bit SmarterWindows/Mac/Linux: Though it may not look very different from other (dubiously beneficial) brain-training games, Brain Workshop is special in that there's a growing body of evidence to suggest that it may actually succeed in making its players a little bit smarter.

Free, cross platform, and open source, Brain Workshop is founded upon the "dual n-back," a tricky sort of memory game where the objective is to keep track of two unrelated sequences of events at once. In most versions of the game, that means paying attention to a spoken list of letters while simultaneously tracking the changing position of a block on a three-by-three grid. Every turn, the game provides a letter and grid position and, every turn, the player has to indicate whether these newest values match the ones given a fixed number of turns ago. The more you play, the higher that number gets. Sound tiring? It can be! But it can also be kind of energizing. The dual n-back is, in that sense, the only brain exercise we've encountered that actually feels like conventional exercise.

If it were like other self-styled "brain games," dual n-back training would probably make you very skilled at dual n-back training and little else. What researchers have found, however, is that, with a little practice, the game can bring about significant improvements in a person's short-term or "working" memory (often abbreviated WM), a faculty the University of Michigan describes as "the ability to maintain information in an active, easily retrieved state, especially under conditions of distraction or interference." It's believed that this improvement in working memory, in turn, can boost "fluid" intelligence, a person's ability to solve unfamiliar problems independent of acquired knowledge.

How much practice does it take to see those effects? Surprisingly little, though it does seem the more you put in, the more you get out. Study participants are generally asked to perform the task about 20 minutes a day for a period of 3 or 4 weeks. While the cognitive benefits of n-back training aren't permanent (and thus require upkeep to maintain), research shows that, at least in schoolchildren, they can persist for up to three months after training has stopped. And, interestingly, new research indicates that single n-back training may be just as effective as the more complicated dual-task sort. (Brain Workshop makes it easy to switch between dual and single n-back modes should you find you prefer one to the other.)

Standard postmodern caveats apply. Your own mileage may vary, yada yada. But, even if the positive effects are in your head, that's where your brains are anyway, right?

Scan Is the Best QR Code Scanner for iPhoneThere are a ton of QR code scanners for iPhone so it almost seems silly to highlight one above the rest, but if you've gone through a bunch of them you know they're not all made equal. Scan is great because you launch it, it's immediately in scanning mode, and it can pick up a code within seconds. There is no BS—it just does its job.

Really, that's all there is to it. You launch it, scan the code (it even works from far away, out of focus, and at an angle), and it provides you with what's inside. If the contents are a URL, it just loads the URL in its built-in web browser. It does its one job really well, so if you need a QR code scanner this is the one to download. And as an added bonus, it's completely free.

Acer unveils Aspire Ethos laptops built to please eyes and ears in the US and Canada

Source: http://www.engadget.com/2011/06/16/acer-unveils-aspire-ethos-laptops-built-to-please-eyes-and-ears/

We got acquainted with Acer's new Aspire Ethos 8951G and 5951G laptops a week ago, and told you all about its hot hardware and its £999 price in the UK. Well, now these marvelous multimedia machines have journeyed across the Atlantic and brought their nifty detachable touchpads, which double as multimedia remotes, with them. The North American versions (named AS8951G and AS5951G) also pack the same 18.4-inch and 15.6-inch HD displays and USB 3.0 ports as their British counterparts. There's Core i5 and Core i7 Sandy Bridge silicon and GeForce GT 555M graphics to give you plenty gaming grunt, and to ensure that the sounds match the visuals, both models pump out 5.1 channel surround sound. Low end audio in the AS5951G comes courtesy of a bass booster, while its big brother has a small subwoofer stuffed in its underside. So, what's the damage to your wallet for these two black beauties? The AS5951G and AS8951G run $1,400 and $1,600, respectively, here in the States, while prices start at $1,200 and $1,500 CAD for our friends in the Great White North. Interested parties can find the full nitty gritty in the PR after the break.

Apple patent application highlights location-based social networking, encourages intimate pinging

Source: http://www.engadget.com/2011/06/16/apple-patent-highlights-location-based-social-networking-encour/

Making friends is hard. Apple knows this. In fact, the company outlined such difficulty in a newly surfaced patent, highlighting the sort of "long and awkward conversation" sometimes required to discover common interests. The patent application, filed back in late-2009, describes a location-based social network that helps users discover people in their vicinity, based on common interests like books, movies, and, naturally, music. Of course, Cupertino already dipped its toes in the social networking waters with the iTunes-based Ping, which, in spite of initial excitement, failed to really capture the imagination of Apple's dedicated base. And this isn't the first time the company has flirted with the idea of location-based social networking either, as a patent that surfaced halfway through last year can attest. The company has clearly learned its lesson with this one, however, and that lesson is: more drawings of women winking and references to Springsteen songs in the application process.
