Chocolate is beloved by...well, most humans, it would seem. But this sweet treat that, for many of us, brings instant happiness, has a nasty secret: most of the world’s cocoa comes from a place where child labor, and sometimes even enslavement, is rampant. For decades, the giant companies that dominate the chocolate industry have said that it was impossible to know if their cocoa was tainted by labor abuses — the supply chain is too long, how can you possibly track cocoa beans back to a small farm in West Africa? Enter technology. But, it turns out, technology may not truly offer the answer to the intractable problem of child labor. The solution may, in fact, be lurking in plain sight. We talk to Nathan Hodge, of Raaka Chocolate; Charity Ryerson, of Corporate Accountability Lab; and Frans Pannekoek, of Tony’s Chocolonely.  Find out more at rawdatapodcast.com

Over the past few decades, computer vision has held the promise of making the world a better place, from aiding the blind to helping doctors better analyze medical imagery. But as it turns out, teaching computers to see has some unintended consequences. Joseph Redmon, a researcher at the University of Washington and computer vision researcher, tells the story of the history of this quickly evolving technology, as well as his own experience seeing a something he built be put to uses he’d never envisioned — applications that might, quite literally, be used to kill.  Find out more at rawdatapodcast.com

In June 2017, something weird — and very alarming — started happening at a company in Copenhagen. It seemed that hackers had shut down the company’s network, and were demanding a ransom. But it turned out this was no ordinary cyberattack. What unfolded was the most devastating cyberattack in history — one that brought operations to a screeching halt in companies across the world, and cost billions of dollars. Andy Greenberg, writer at Wired Magazine and author of the book Sandworm, tells the behind-the-scenes story of the attack, dubbed NotPetya — which, in its aftermath, was revealed to be not a sophisticated tool to steal money, but instead, a weapon designed to destroy a nation.   Find out more at rawdatapodcast.com

Get out your smartphone, and you can almost instantaneously know where you are — and find out how to get where you want to go. Which, when you think back on the history of human navigation is...pretty astounding. How did we come to hold such immense power in our hands? It’s all thanks to GPS, a technology born from the Cold War and the Space Race, and delivered into our personal pocket computers thanks to a series of dramatic, sometimes tragic events, and at least one war. Our guide is Paul Ceruzzi, a former curator at the Smithsonian and author of the book GPS. And Jordan Frith, a professor at Clemson University, talks about it means now that, for better or worse, we never have to get lost ever again.

Originally broadcast in April 2019. As we approach the end of 2019, the Financial Times recognizes Shoshana Zuboff's "The Age of Surveillance Capitalism" as one of the best business books of the year. Shoshana Zuboff doesn’t mince words when it comes to the data economy. According to Zuboff, author of the recent book *The Age of Surveillance Capitalism, *our very souls are at stake. But the seeds of surveillance capitalism were planted rather innocently, back in the heady days of the dotcom bubble. As Zuboff tells it, it all began with Google. When the young company entered crisis mode, they needed to find new ways to make money. And a whole new economic logic was born — one that has now spread across every sector of the economy, and has invaded every facet of our online lives. Zuboff warns that surveillance capitalism threatens much more than just our privacy. Find out more at rawdatapodcast.com

When humans predict something, it’s basically an educated guess, based on our experiences. When a machine makes a prediction, it uses data and math. And we are increasingly relying on machine prediction to help make decisions in everything from banking to insurance to education. But Meredith Broussard, a professor from New York University, argues that this has all gone too far, especially when you look at what data are being used in machine predictions. And that the “futures” that machines predict should be taken with large grains of salt. Find out more at rawdatapodcast.com

Imagine a life without the Internet. No email, no Instagram, no texting, no Google maps, no Netflix...what would you do? A “normal” life would be next to impossible. But huge numbers of Americans face this very problem. Access to high-speed Internet is still an enormous challenge for a lot of people. We talk with Nicol Turner Lee, a fellow at the Brookings Institution, about what it means to be “digitally invisible,” and the toll lack of access takes. It’s a complicated problem, and one with no easy answers. And, for some context, we take a trip through time to see how America tackled a similarly dire issue at the height of the Great Depression.

In the world of computer science, being a hacker means you know what’s up, and you have street cred. Outside of technology circles, though, hacking is more associated with things like data breaches, ransomware, and malware. So where does the term come from, and why does it have different meanings to different people? In our conversation with Meredith Broussard, a professor at New York University, we explore the roots of hacking, and what it says about society’s relationship with technology today.

It’s 2019, and machine learning is everywhere. It might not be Skynet, but it can still sound a little scary. If the robot apocalypse isn’t around the corner, what is? We talk to Kantwon Rogers, a lecturer at Georgia Tech and frequent guest of the show, to demystify this increasingly omnipresent technology. We learn about about how the heck machine learning actually works, how it’s being used to improve our lives, and what should be keeping us awake at night when it comes to this powerful technology. (Hint: It’s not because of killer robots. Not yet...) Find out more at rawdatapodcast.com

What exactly is memory? And why is it so important to how our devices work today? Friend of the show and Georgia Tech computing lecturer Kantwon Rogers breaks it down into bits and bytes — and hints at what kinds of clouds the future may bring. BONUS: Andrea offers up her global solution to solve the issue of tailgating. Find out more at rawdatapodcast.com
