The Art of Data Visualization: Learn 7 visualizations in R. With ever increasing volume of data, it is impossible to tell stories without visualizations.
Data visualization is an art of how to turn numbers into useful knowledge. R Programming lets you learn this art by offering a set of inbuilt functions and libraries to build visualizations and present data. Before the technical implementations of the visualization, let’s see first how to select the right chart type. Selecting the Right Chart Type There are four basic presentation types: ComparisonCompositionDistributionRelationship To determine which amongst these is best suited for your data, I suggest you should answer a few questions like, How many variables do you want to show in a single chart? Below is a great explanation on selecting a right chart type by Dr. Understanding the emotional act of voting : Nature Human Behaviour. The mass media often suggests that people do not care about elections, that many abstain because they are not interested, but we repeatedly find that elections are actually a time of heightened emotion for many people.
In many elections, 20 to 30% of voters either make up or change their minds within a week of the vote, about half of them on election day itself1, a figure which commercial surveys confirmed yet again during the 23 June referendum in the UK. This finding obliges us to consider more carefully what comes to disrupt known patterns of electoral decision-making, which invariably implies understanding more about the emotional act of voting and how voters' emotions interact with institutional design (for example, whether citizens have to vote in polling stations or can do so from home, how ballot papers are designed, or how young people's first election is organized)2. Digital in 2016 - We Are Social UK. Today, we’re very excited to share our huge new Digital in 2016 report: We Are Social’s comprehensive study of digital, social and mobile usage around the world.
Last year’s global report has already been read almost 2 million times on SlideShare, but we’ve also had many requests for information on other countries, so this year we’ve decided to produce a report in three distinct parts: Science Says Women Need More Sleep Than Men Because Their Brains Work Harder. Great news, ladies!
Science has shown that because the brain of a woman is more complex than the brain of a man, she needs more sleep. Director of the Speech Research Centre at England’s Loughborough University Professor Jim Horne explains: “For women, poor sleep is strongly associated with high levels of psychological distress and greater feelings of hostility, depression, and anger.” Apple’s Next Encryption Battle Is Likely Playing Out in Secret in a Boston Court.
Apple's next big encryption battle with the federal government appears to be unfolding in a largely secret court case in Massachusetts involving an FBI bust of a gang called the Columbia Point Dawgz.
Thursday, the American Civil Liberties Union filed a motion to unseal a list of documents in the case (embedded below), in which the government appears to be trying to use the controversial All Writs Act of 1789 to force Apple to help it decrypt what is believed to be an iPhone 6 Plus running iOS 9.1.

Personal details of nearly 50 Million Turkish citizens, including the country's President Recep Tayyip Erdogan, have been compromised and posted online in a massive security breach.
Traffic From Streaming Web Video Expected to Grow by at Least 1300% That streaming videos makes up a huge percentage of the Internet's traffic is by now well-known.
Netflix alone makes up nearly 30% of all downstream traffic and we're now accustomed to hearing about the extraordinary amount of bandwidth eaten up by videos streaming during major news events. For example, during President Obama's inauguration, content delivery network Akamai delivered 7 million simultaneous streams of video, with traffic surpassing two terabytes per second (Tbps), which broke records. The next year, Akamai's network traffic peaked at about 3.45 Tbps. If you think we're eating up a lot of bandwidth streaming video now, just wait. That 3.45 Tbps figure from last year will be blown out of the water within five years, according to a detailed report put together by Akamai, Harvard University and University of Massachusetts. This growth is not guaranteed to be smooth, either.
The Billionaire King of Techtopia: Critical Eye. When Peter Thiel ventures outside for a run, typically in the early-early morning, when the fog drifts low and slow into the San Francisco Bay, he's often drawn to what the poet Lawrence Ferlinghetti called "the end of land and land of beginning.
" That means the San Francisco waterfront—especially the one-and-a-half-mile stretch of pathway hugging the marshy shoreline from Crissy Field to the base of the Golden Gate Bridge.

As the Obama administration comes to an end, so does the innovation-focused tenure of Ashton Carter as secretary of defense.
Under his leadership and the guiding precepts of the third offset, the Department of Defense initiated a series of Silicon Valley-inspired innovations. From chief innovation officers to the Strategic Capabilities Office and Defense Innovation Unit-Experimental, Carter’s Pentagon has focused on institutionalizing innovation. Unfortunately and as many other commentators have noted, this focus on top-down innovation may have unwittingly created innovation architectures that bypass the warfighter. As a result, critics question whether warfighter-led innovation can thrive in the third offset.
Nowhere is this critique more relevant or more concerning than in cyberspace, a domain characterized by prolific users, rapid evolution of capabilities, and persistent confrontation. Why Warfighter-Led Innovation Matters The Current State of Cyber Innovation Beyond Offset. Edward Snowden’s New Research Aims to Keep Smartphones From Betraying Their Owners. In early 2012, Marie Colvin, an acclaimed international journalist from New York, entered the besieged city of Homs, Syria, while reporting for London’s Sunday Times.
She wrote of a difficult journey involving “a smugglers’ route, which I promised not to reveal, climbing over walls in the dark and slipping into muddy trenches.” Despite the covert approach, Syrian forces still managed to get to Colvin; under orders to “kill any journalist that set foot on Syrian soil,” they bombed the makeshift media center she was working in, killing her and one other journalist and injuring two others. Syrian forces may have found Colvin by tracing her phone, according to a lawsuit filed by Colvin’s family this month. Syrian military intelligence used “signal interception devices to monitor satellite dish and cellphone communications and trace journalists’ locations,” the suit says.

How Covert Agents Infiltrate the Internet to Manipulate, Deceive, and Destroy Reputations. Panama Papers graphically demonstrate the power of the graph database. Graph databases have proved their worth with the technology being used to analyse the Panama Papers. The recent data leak from the Panamanian law firm Mossack Fonseca has captured the imaginations of the world, and in particular journalists at the Washington-based, International Consortium of Investigative Journalists (ICIJ), which includes The Guardian and the BBC in its membership list. The consortium fed the leaked data into a graph database, in this case Neo4j, which crunched the data and then revealed the underlying structure of that data -- thus illustrating the relationships between all of the individuals, companies, and customers involved.
A graph database is designed, like any other database, to handle large volumes of data. X-Files revival inspired by surveillance revelations, says show's creator. The new series of The X-Files has been partly prompted by recent exposés about government snooping, according to the show’s creator, Chris Carter. “It’s a perfect time to come back with the X-Files considering global politics,” said Carter, who was speaking in Cannes shortly after the first episode of the new series had premiered. “We’re trying to be honest with the changes dealing with digital technology: the capability of spying. Clearly we’re being spied on in the US – or at least spying on you – and there seems to be no shame in it.” The new six-episode series reunites agents Mulder and Scully – reprised by David Duchovny and Gillian Anderson – with its first episode setting up a series arc promising “the most evil conspiracy the world has ever known”.
Fans can expect some tearing up of history – “Roswell?
