But when Ranganth told Shaw about the problems, the data scientist had an idea. Why not take a shortcut? Foursquare already had a massive database of check-ins — location information about the places its users most liked to go. And this data didn’t just include the place where someone had checked in. It showed how strong the GPS signal was at the time, how strong each surrounding Wi-Fi hotspot signal was, what local cell towers were nearby, and so on. Leveraging this data meant that Foursquare could still grab a good current location even if users were underground, near a source of radio interference, or facing some other signal obstacle. Chances are, some prior Foursquare user had seen the world through the same flawed eyes and reported his or her location.
“It’s one thing for us to match one point to another point, but we have a lot more options when we can match a cloud of points to another cloud of points,” Ranganth says. “It was very much an ah-ha moment for everybody.””

Born in Denmark in 1978, John Kenn spends his days writing and directing television shows for kids. When he has time between TV and his twins, he draws his creepy little monster drawings on post-it notes, peeking into a little window into a different world, made entirely on office supplies.

What is the furthest one human being has ever been from every other living person? Were they lonely?
It’s hard to know for sure!
The most likely suspects are the six Apollo command module pilots who stayed in lunar orbit during a Moon landing: Mike Collins, Dick Gordon, Stu Roosa, Al Worden, Ken Mattingly, and Ron Evans.
Each of these astronauts stayed alone in the command module while two other astronauts landed on the Moon. At the highest point in their orbit, they were about 3,585 kilometers from their fellow astronauts.
You’d think astronauts would have a lock on this category, but it’s not so cut-and-dry. There are a few other candidates who come pretty close!

The diet industry is broken. Lift is going to fix this.
Everything people think they know about diet is contradicted somewhere else. What diets work? What does it even mean for a diet to work? Weight loss? Long term health? Enjoyment?
We’re partnering with Berkeley and Stanford to answer…

"Both my kids will have graduated from college in 4.5 years, and I’m heading to Mexico. I’m not kidding. Social Security goes a long way down there. For $300 a week, I could have a place to stay, a satellite dish, a fishing pole, and some rum."
