TIME

What happens when the cameras stop rolling on reality television? Gabrielle Union busts some behind-the-scenes myths as she plays a Bravo reality star in the new film Top Five, which Chris Rock wrote, directed and also stars in.

TIME caught up with the actress last month to talk about wedding planning, her favorite rappers and what the film, which hits theaters Dec. 12, gets right about celebrity.

TIME: How do you prepare for the role of a Bravo housewife?
Gabrielle Union: Well, I didn’t look at the Housewives — she’s written as having created this empire off of her show with her sisters. I know a few big reality TV stars, and I knew them before they became big reality TV stars. What I wanted to show with Erica was their intelligence and their power and the fact that they are not being lead around by the nose. They…

After initially mapping 8 million flood-related tweets throughout the region over the past couple years as part of a Twitter Data Grant, the University of Wollongong and a local emergency agency have developed a project called PetaJakarta that builds a real-time map of areas affected by floods, based on geo-tagged tweets directed to the project using a specific hashtag. According to a Twitter blog post announcing the project, the goal is to help emergency workers and citizens in one of the world’ most-populous areas understand how floods are moving and what areas have been hit the hardest.

Follow the Sand to the Real Fracking Boom

TIME

This post originally appeared on OilPrice.com.

When it takes up to four million pounds of sand to frack a single well, it’s no wonder that demand is outpacing supply and frack sand producers are becoming the biggest behind-the-scenes beneficiaries of the American oil and gas boom.

Demand is exploding for “frac sand”–a durable, high-purity quartz sand used to help produce petroleum fluids and prop up man-made fractures in shale rock formations through which oil and gas flows—turning this segment into the top driver of value in the shale revolution.

“One of the major players in Eagle Ford is saying they’re short 6 million tons of 100 mesh alone in 2014 and they don’t know where to get it. And that’s just one player,” Rasool Mohammad, President and CEO of Select Sands Corporation told Oilprice.com.

Frack sand exponentially increases the return on investment for a well, and oil…

Half of Americans Don’t Know What a Privacy Policy Is

TIME

It looks like Facebook’s privacy-focused blue dinosaur has some more work to do, as a new survey from the Pew Research Center finds that 52% of American Internet users don’t actually know what a privacy policy is.

A majority of respondents believe that when a company posts a privacy policy, “it ensures that the company keeps confidential all the information it collects on users.” Only 44% of survey respondents knew that answer was false — a privacy policy simply states whatever rules a website has drafted to determine how it will share and use people’s data. Such policies often include fine print that actually make people’s data less private than they might expect, allowing it to be used in ads or handed off to third parties.

With so few people who understand privacy policies, it’s no wonder that a bogus Facebook post proclaiming to protect people’s copyright went viral this…
