The Download: Ukraine’s drone defenses, and today’s climate heroes

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Meet the radio-obsessed civilian shaping Ukraine’s drone defense

Drones have come to define the brutal conflict in Ukraine that has now dragged on for more than two and a half years. And most rely on radio communications—a technology that Serhii “Flash” Beskrestnov has obsessed over since childhood.

While Flash is now a civilian, the former officer has still taken it upon himself to inform his country’s defense in all matters related to radio. Once a month, he studies the skies for Russian radio transmissions and tries to learn about the problems facing troops in the fields and in the trenches.

In this race for survival—as each side constantly tries to best the other, only to start all over again when the other inevitably catches up—Ukrainian soldiers need to develop creative solutions, and fast. As Ukraine’s wartime radio guru, Flash may just be one of their best hopes for doing that. Read the full story.

The big story

What does GPT-3 “know” about me?

August 2022

One of the biggest stories in tech is the rise of large language models that produce text that reads like a human might have written it.

These models’ power comes from being trained on troves of publicly available human-created text hoovered up from the internet. If you’ve posted anything even remotely personal in English on the internet, chances are your data might be part of some of the world’s most popular LLMs.

Melissa Heikkilä, MIT Technology Review’s senior AI reporter, wondered what data these models might have on her—and how it could be misused. So she put OpenAI’s GPT-3 to the test. Read about what she found.

In this section yesterday we stated that Amazon had acquired iRobot. This was incorrect—the acquisition never completed. We apologize for the error.
