Ingrid Betancourt: What six years in captivity taught me about fear and faith


In 2002, the Colombian guerrilla movement known as the FARC (Revolutionary Armed Forces of Colombia) kidnapped Ingrid Betancourt in the middle of her presidential campaign. For the next six years, Betancourt was held hostage in jungle prison camps where she was ravaged by malaria, fleas, hunger and human cruelty until her rescue by the Colombian government. In this deeply personal talk, the politician turned writer explains what it's like to live in a perpetual state of fear -- and how her faith sustained her. (In Spanish with English subtitles.)

Joseph Redmon: How computers learn to recognize objects instantly


Ten years ago, researchers thought that getting a computer to tell the difference between a cat and a dog would be almost impossible. Today, computer vision systems do it with greater than 99 percent accuracy. How? Joseph Redmon works on the YOLO (You Only Look Once) system, an open-source method of object detection that can identify objects in images and video -- from zebras to stop signs -- with lightning-quick speed. In a remarkable live demo, Redmon shows off this important step forward for applications like self-driving cars, robotics and even cancer detection.

Meet Françoise Mouly, The New Yorker's art director. For the past 24 years, she's helped decide what appears on the magazine's famous cover, from the black-on-black depiction of the Twin Towers the week after 9/11 to a recent, Russia-influenced riff on the magazine's mascot, Eustace Tilley. In this visual retrospective, Mouly considers how a simple drawing can cut through the torrent of images that we see every day and elegantly capture the feeling (and the sensibility) of a moment in time.

Grace Kim: How cohousing can make us happier (and live longer)

Rethink your home and how you live in it with this eye-opening talk.
