How a bot-fighting test turned into edtech’s most iconic brand, Duolingo

Luis von Ahn, an entrepreneur who has dedicated his career to scaling free education, has probably annoyed you more than once. In fact, you’ve likely been annoyed by his work dozens and maybe hundreds of times over the years. A decade before he co-founded the whimsical and language-learning app Duolingo, one of the most popular education apps in the world with over 500 million downloads and 40 million active users, he was building the technology that would become CAPTCHA, those human-annoying bu...

Eureka: A family of computer scientists developed a blueprint for machine consciousness

Renowned researchers Manuel Blum and Lenore Blum have devoted their entire lives to the study of computer science with a particular focus on consciousness. They’ve authored dozens of papers and taught for decades at prestigious Carnegie Mellon University. And, just recently, they published new research that could serve as a blueprint for developing and demonstrating machine consciousness. That paper, titled “A Theoretical Computer Science Perspective on Consciousness,” may only a be a pre-print ...

Guest post by Samir Khuller on attending The TCS Women 2019 meeting

(I will post the solution to the problem in the last blog later in the week---probably Thursday. Meanwhile, enjoy these thoughts from Samir Khuller on the TCS Women 2019 meeting.) Guest Post by Samir Khuller: Am I even allowed here?” was the first thought that crossed my mind when I entered the room. It was packed with women (over 95%), however a few minutes later, several men had trickled in. I was at the TCS Women spotlight workshop on the day before STOC. Kudos to Barna Saha, Sofya Raskhodni...

An Immerman-Szelepcsényi Story

As a grad student in the late 80's I had the opportunity to witness many great and often surprising theorems in computational complexity. Let me tell you about one of them, the Immerman-Szelepcsényi result that nondeterministic space is closed under complement. I wish I had the original emails for this story but instead I'm working from memory and apologies if I get some of the details wrong. I'm expanding from a short version from the early days of this blog. I started my graduate work at UC Be...

Richard Feynman (1918-1988)

When I took cryptography from Manuel Blum, he handed out copies of the chapter "Safecracker Meets Safecracker" from Richard Feynman's book Surely You're Joking Mr. Feynman. Feynman, the Nobel Prize winning physicist who was born a hundred years ago today, wrote this book not about physics but just a series of stories from different times in his life. This chapter described how Feynman learned how to open locked safes in Los Alamos during the Manhattan Project. We all have interesting stories to...

Tech Nightmares That Keep Turing Award Winners Up At Night

itwbennett writes: At the Heidelberg Laureate Forum in Germany this week, RSA encryption algorithm co-inventor Leonard Adelman, "Father of the Internet" Vint Cerf, and cryptography innovator Manuel Blum were asked "What about the tech world today keeps you up at night?" And apparently they're not getting a whole lot of sleep these days. Cerf is predicting a digital dark age arising from our dependence on software and our lack of "a regime that will allow us to preserve both the content and the s...
