This Awesome Graph Shows Just How Boring Class Really Is
Source: http://www.businessinsider.com/this-awesome-graph-shows-just-how-boring-class-really-is-2012-11
This great graph, taken using a wearable sensor, shows a student’s emotional, physical, and mental arousal during all different phases of every day of the week.
The device measures what’s called Electrodermal Activity — which measures the activity of the sympathetic nervous system, best known to control the fight-or-flight response. It is activated by emotional arousal, increased cognitive workload, or physical exertion.
Spikes pop up during lab work, exams, studying, and sleep, but what’s stunning is how low activity levels were during this student’s classes. They must have been super boring.

The chart comes from a May 2010 paper via JoiIto. You can download the paper here.

Analytics Show Facebook Curbs The Reach Of Big Brands’ Posts
Source: http://www.businessinsider.com/facebook-curbs-the-reach-of-big-brands-2012-11
Billionaire entrepreneur Mark Cuban and “Star Trek” actor George Takei both complained recently that Facebook reduced the “reach” of their posts, limiting the number of fans likely to see any given post.
More seriously, two executives at major social media agencies owned by WPP group claimed the same thing — only with data.
In response, Facebook formally denied that it is “gaming” its Edgerank post algorithm to reduce the reach of posts (and thus force advertisers to pay to promote posts to reach all their fans).
Now comes PageLever, a Facebook analytics company, which gave Mashable some data that shows that the bigger fanbase your Facebook page has, the lower reach any individual post has. Brands with small fanbases of fewer than 10,000 people can get nearly 20 percent of them to see any individual post. But brands like Coca-Cola and Walmart, who have more than 1 million fans, can only get about 6 percent of them to see any given post — unless they pay:

The data suggest Facebook’s algorithm discriminates against bigger brands. It encourages smaller brands by offering them triple the reach of their larger competitors. But the more successful a brand becomes on Facebook, the more its organic average reach dwindles.! p>
By the time any company has more than 100,000 fans, of course, they’re pretty dependent on Facebook as a marketing medium — and thus may be more likely to pay to promote posts.

There was quite a stir sparked last week when it was revealed that Google was exploiting a loophole in a Apple’s Safari browser to track users through web ads, and that has now prompted a response from Microsoft’s Internet Explorer team, who unsurprisingly turned their attention to their own browser. In an official blog post today, they revealed that Google is indeed bypassing privacy settings in IE as well, although that’s only part of the story (more on that later). As Microsoft explains at some length, Google took advantage of what it describes as a “nuance” in the P3P specification, which effectively allowed it to bypass a user’s privacy settings and track them using cookies — a different method than that used in the case of Safari, but one that ultimately has the same goal. Microsoft says it’s contacted Google about the matter, but it’s offering a solution of its own in the meantime. It’ll require you to first upgrade to Internet Explorer 9 if you haven’t already, then install a Tracking Protection List that will completely block any such attempts by Google — details on it can be found at the source link below.
As ZDNet’s Mary Jo Foley notes, however, Google isn’t the only company that was discovered to be taking advantage of the P3P loophole. Researchers from Carnegie Mellon University’s CyLab say they alerted Microsoft to the vulnerability in 2010, and just two days ago the director of the lab, Lorrie Faith Cranor, wrote about about the issue again on the TAP blog (sponsored by Microsoft, incidentally), detailing how Facebook and others also sk! irt IE’s ability to block cookies. Indeed, Facebook readily admits on its site that it does not have a P3P policy, explaining that the standard is “out of date and does not reflect technologies that are currently in use on the web,” and that “most websites” also don’t currently have P3P policies. On that matter, Microsoft said in a statement to Foley that the “IE team is looking into the reports about Facebook,” but that it has “no additional information to share at this time.”
Update: Google’s Senior Vice President of Communications and Policy, Rachel Whetstone has now issued a statement in response to Microsoft’s blog post. It can be found in full after the break.
Microsoft finds Google bypassed Internet Explorer’s privacy settings too, but it’s not alone (update: Google responds) originally appeared on Engadget on Mon, 20 Feb 2012 16:59:00 EDT. Please see our terms for use of feeds.

After The Regretsy and Diaspora Account Freezes, We
Source: http://techcrunch.com/2011/12/06/paypal-account-freeze/
Hey PayPal, do you realize people no longer trust you? By heartlessly freezing the accounts of legitimate causes, you’ve shaken our confidence. By releasing the funds only in response to public pressure, you’ve shown that your policy enforcement is erratic and our money can disappear on a whim. The account freezes have become such fiascoes that they transcend the facts. Even if you’re boxed in by the law, even if these companies accidentally misused your product, it doesn’t matter. The public’s perception is that there’s a risk in keeping money with PayPal. If something doesn’t change, startups, causes, and merchants will start processing donations and payments elsewhere.
Today’s blunder where you froze the account of Regretsy as it tried to buy toys for poor kids is going to stick in people’s minds for a long time. It follows you freezing accounts of open source social network Diaspora, Minecraft creator Markus Persson, and social network for models Zivity. I won’t even get into your controversial stance on Wikileaks.
Sure, we don’t hear about the countless people you save from spammers, fraudsters, and thieves. But again, this is a public relations issue, and you need to be winning the hearts and minds. You’re essentially a bank, and banks are built on trust. That trust erodes with every errant account freeze. If I was an organization depending you, I’d be worried, and would consider withdrawing all my money. Unfortunately, that very action could lead my account to be frozen.
So get smart, and change how you deal with these issues. Here’s how:
1. Appoint a rapid response team to either pre-approve or immediately review any high-profile or contested account freezes.
2. Change your system to prevent people from using the Donation button if they aren’t a non-profit, or accidentally misusing any other feature.
3. Clearly explain to users that rapidly withdrawing large sums of money may trigger an account review, and suggest they regularly withdraw smaller sums instead.
This isn’t a comprehensive list, but it would probably help you avoid of large volume of erroneous account freezes. If some of these measures are already in place, they’re not working properly. Also, be less of a grinch. You’re a giant company, you could afford to give those Regretsy kids some extra toys or provide some token of good faith to those you’ve screwed.
PayPal, you’re the incumbent, and people are slow to switch to an unproven smaller payment service. But considering WePay dumped a 600 lb chunk of frozen money in front of your conference, startups are gunning for you. That first-mover advantage won’t hold up forever. As more commerce moves online, you’re going to have to uphold the trust of mainstream users that are highly influenced by bad press. And right now, you’re on thin ice.
