The report projects implications of the Internet’s transformative potential to Africa’s financial services, education, health, e-commerce, agriculture, and government sectors.
Africa’s digital development is accelerating. A new report from the McKinsey Global Institute says the Internet could account for $300 billion of GDP by 2025.

So says a new research paper written by Jon Kleinberg, a computer scientist at Cornell University, and Lars Backstrom, a senior engineer at Facebook. The paper, posted online on Sunday, will be presented at a conference on social computing in February.
The pair used a hefty data set from Facebook as their lab: 1.3 million Facebook users, selected randomly from among all users who are at least 20 years old, with from 50 to 2,000 friends, who list a spouse or relationship partner in their profile. That makes for a lot of social connections to analyze, roughly 379 million nodes and 8.6 billion links. The data was used anonymously.
Their key finding was that the total number of mutual friends two people share — embeddedness, in social networking terms — is actually a fairly weak indicator of romantic relationships. Far better, they found, was a network measure that they call dispersion.
“A spouse or romantic partner is a bridge between a person’s different social worlds,” Mr. Kleinberg explained in an interview on Sunday.

Big Data Hits Real Life: Brick-and-mortar stores are looking for a chance to catch up with their online competitors by using software that allows them to watch customers as they shop, and gather data about their behavior.
Using video surveillance, and signals from shoppers’ cellphones and apps, retailers are tracking customers’ behavior and moods.

One of the biggest personal data collectors around is getting ready to open its vaults to the public. According to Forbes, you'll soon be able to request your personal files from Acxiom, a marketing company that holds a database on the interests and details of over 700 million people. That database reportedly holds information on consumers' occupations, phone numbers, religions, shopping habits, and health issues, to name a few. That data has traditionally been given only to marketers — for a fee, of course — but Acxiom has decided to let consumers peer into its database as well. Whether individuals will have to pay too is still up for debate, but it's been decided that a person can only view their own file.

Yet facial recognition technology is still a work in progress. While investigators in the Boston marathon bombing had multiple images of both suspects, the technology did not come up with a match. They were not identified by their faces, but by their fingerprints! Authorities won't say what went wrong. One possibility is that government data banks - through which the photos would've been searched - are not big enough.

First you’re smitten by a social network or Web service and can’t stop spending time on it. Then it starts asking how you’re feeling, what you like, where you are, with whom, and why you don’t share as much anymore.
Pretty soon, you’re ready to call it quits.
But trying to end your relationship with some prominent online services can be like breaking up with an overly attached romantic partner — they make it pretty hard to say goodbye.
And with good reason — more users are beneficial to a company’s bottom line, which often depends on generating revenue by selling you targeted advertisements. Possibly no social network understands this better than Facebook, whose chief executive, Mark Zuckerberg, proudly announced last October that his site had surpassed one billion active users.
“Their business model is about getting users to create content,” said Jeremiah Owyang, an industry analyst with the Altimeter Group. “It’s users who are creating content, liking things, and, ultimately, a brand sees this and comes to deploy advertising dollars. The product is us.”

Disruptive as the attacks were, they were by today’s standards primitive, consisting of “distributed denial of service” attacks (DDoS), which essentially overload servers with signals from hijacked, hacker-controlled PCs. Six years later, as computing power and IT dependency have increased hugely, cyberattacks are far more sophisticated and our vulnerabilities are far greater.

Most Internet users have become accustomed to using Facebook to keep up with friends — or at least, Facebook “friends” — while using more specialized sites and apps to search for restaurants, books and people. But if you have built up a network of friends on Facebook, those connections can now help you find people, places and things in the real world, in ways that more specialized sites like Google, Yelp and Amazon cannot.

BAD NEWS SELLS. If it bleeds, it leads. No news is good news, and good news is no news.
Those are the classic rules for the evening broadcasts and the morning papers, based partly on data (ratings and circulation) and partly on the gut instincts of producers and editors. Wars, earthquakes, plagues, floods, fires, sick children, murdered spouses — the more suffering and mayhem, the more coverage.
But now that information is being spread and monitored in different ways, researchers are discovering new rules. By scanning people’s brains and tracking their e-mails and online posts, neuroscientists and psychologists have found that good news can spread faster and farther than disasters and sob stories.

In agreeing to settle a case brought by 38 states involving the project, the search company for the first time is required to aggressively police its own employees on privacy issues and to explicitly tell the public how to fend off privacy violations like this one.
While the settlement also included a tiny — for Google — fine of $7 million, privacy advocates and Google critics characterized the overall agreement as a breakthrough for a company they say has become a serial violator of privacy.

Although algorithms are growing ever more powerful, fast and precise, the computers themselves are literal-minded, and context and nuance often elude them. Capable as these machines are, they are not always up to deciphering the ambiguity of human language and the mystery of reasoning. Yet these days they are being asked to be more humanlike in what they figure out.
And so, while programming experts still write the step-by-step instructions of computer code, additional people are needed to make more subtle contributions as the work the computers do has become more involved. People evaluate, edit or correct an algorithm’s work. Or they assemble online databases of knowledge and check and verify them — creating, essentially, a crib sheet the computer can call on for a quick answer. Humans can interpret and tweak information in ways that are understandable to both computers and other humans.
For example, when Mitt Romney talked of cutting government money for public broadcasting in a presidential debate last fall and mentioned Big Bird, messages with that phrase surged. Human judges recognized instantly that “Big Bird,” in that context and at that moment, was mainly a political comment, not a reference to “Sesame Street,” and that politics-related messages should pop up when someone searched for “Big Bird.” People can understand such references more accurately and quickly than software can, and their judgments are fed immediately into Twitter’s search algorithm.

Carnegie Mellon University conducted a study following more than 5,000 Facebook users over six years, from 2005 and 2011, and found that changes in the social network's privacy policies caused users to share more -- not less -- personal data. Lest you think this means that users suddenly trusted the site more, Carnegie Mellon says that Facebookers became more and more protective of their personal details as the social network grew in membership -- and that the uptick in shared information is a result of increasingly granular privacy settings. If you recall, Facebook introduced new in-depth privacy controls in 2010, and the study found that the release of these new settings corresponded to users sharing more personal data, both within their network of friends and with strangers and third-party applications.

Also to note that "why Big Data doesn't care about causes, just correlation"
"They crunched the numbers, and they found out that cars that were orange tended to not have breakdowns compared to other colors of cars ... So why might this be? Well, we can sort of concoct different scenarios. One is that orange tends to be a custom color, and if you order an orange car, perhaps the rest of the car was made in a custom way, a little bit more care was taken into it. We don't know why, and it's frankly, it's not that important. It might just bring us down a rabbit hole for us to try to find out why. But, again, if you just want to buy a car that's not going to break down, go with the correlation."

In summary, these are the three key findings for each channel:
Facebook: Strongest channel for driving visits
LinkedIn: Strongest channel for driving pageviews
Twitter: Strongest channel for driving leads
This data reveals that one social channel might be more effective than another based on the goal you're trying to accomplish. However since they all have different strengths, an integrated marketing approach will give you the greatest results for your effort.

As Facebook and Twitter become as central to workplace conversation as the water cooler, regulators are ordering employers to scale back policies that limit what workers can say online.
The government, frustrated by its inability to tax U.S. digital giants active in France, has outlined a new levy that would be a tax on the collection of personal data.
