For LinkedIn Members, their network and relationships are a rich source of insights and opportunity. In short, these relationships matter. Our members are also increasingly mobile – over 50% of them will use LinkedIn from a mobile device by the end of this year. Mobile devices enable us to better understand a member’s context, opening up some interesting ways for us to deliver LinkedIn’s value to them. This post focuses on the engineering behind LinkedIn Connected, our brand new iOS app that is replacing LinkedIn Contacts. LinkedIn Connected is designed to give members relevant, and timely, reasons to reach out and keep in touch with the people in their network. Connected also includes LinkedIn’s first anticipatory computing feature, and this post will discuss the platform we are building to enable more and more of these. http://engineering.linkedin.com/building-linkedin-connected

Media outlets everywhere shouted news that the 3-year-old ride-sharing service Uber charted an eye-popping valuation of up to $18.2 billion, after closing its venture capital round that raised $1.2 billion. In fact, by Forbes’ numbers, Uber is now worth more than Avis and Hyatt combined. For those who have been sequestered with monks somewhere up in the Himalayas, here’s what’s behind all the fuss. With Uber, customers can send a text message on a mobile app through the service to reserve a car. Uber charges for the ride based on distance traveled, or time, or demand, or a combination of all three. Uber is also the latest case study of how the “Internet of Things” is driving both innovation and disruption, if you’ll excuse the pun. The IoT is a phenomenon that is both real and here today. Just ask Uber and their customers. It not only means better, more personalized service, it means billions of connected devices resulting in billions and billions of dollars. http://bit.ly/1m2sULF

You click a button, the computer wurrs, and out comes a spidery pentagon that claims to map your personality. That pentagon is the product of a software startup called Five, which launched the personality-mapping tool Tuesday. The company analyzes Facebook posts and parses their language structure to deduce a user’s personality. The website then maps your personality on five axes that correspond to five character traits—extraversion, agreeableness, conscientiousness, neuroticism, and openness. According to Business Insider, the five traits were drawn from a study conducted at the University of Pennsylvania, which identified those traits as the “Big Five”. The site also lets you see which of the personality prognoses of your friends and compare your compatibility. It also includes the personalities of major figures, who range from Barack Obama to Mahatma Gandhi. I, for example, was classified as spontaneous and analytical—a deduction drawn from my exceedingly sparse Facebook presence. Five Labs also told me that I am 54 percent similar to Andy Warhol, while (shockingly!) only 8 percent similar to Oprah Winfrey. Five Labs founder Nikita Bier told the New York Times Wednesday that he has seen an initially strong response to the tool. According to a Facebook post by Bier, 45 million people created profiles to have their personalities analyzed during the first 24 hours that the tool was live. The tool obviously has some flaws (its prognoses seemed wildly off base for a few of my Facebook friends). And the wild enrollment may owe more to the site’s seamless design than the quality of its personality predictions. But what’s creepiest and perhaps most enlightening about the tool is that it offers a look at what major companies like Google and Facebook may be able to deduce from looking at our behavior online. Those companies have developed increasingly sophisticated tools to quantify user personalities and preferences in recent years and at least this tool offers us a window into how a company could do that. http://www.boston.com/business/technology/2014/06/12/new-online-tool-can-map-your-personality/4Pu9Offr3ZwWoLEZ91KyLO/story.html

Around the world teams of scientists are working on the next technological revolution: quantum computing. But what makes it so special? And why do we need it? We ask physicist Dr. Ruth Oulton of the Bristol University to explain. http://www.theguardian.com/science/2014/mar/06/quantum-computing-explained-particle-mechanics
