Kashif Hoda was getting onto a Southbound train at Harvard Square when a young man said he recognized him. The doors closed before he got a chance to ask the young man how, or who he was. A month later, the answer came in the form of a viral video.

Harvard students AnhPhu Nguyen and Caine Ardefyio modified Meta's smart glasses so that you can search someone's face quickly, almost without them knowing, and pull up personal internet...

Adam Aleksic's Roman Empire is language, particularly how algorithms are changing the way we all use words. This week, Endless Thread gets algospeak-pilled and learns how "unalive" spread from a kids' Spider-Man cartoon to TikTok mental health communities trying to avoid censorship; what we're really saying when we say we're "goblin-core," and whether this all means we're "cooked."

Who gets credit for starting a meme? Usually... nobody — they're made too quickly and organically. In the case of one of the most famous bait-and-switch memes of all time, the "Rick Roll," we may be looking at something experts call convergent evolution. Did the Rick Roll originate with a piece of code on the message board 4Chan, or with a prank call to a local sports show in Michigan? And why does the Rick Roll have such staying p...

2025 marks 20 years of Google Maps — a tool that many of us would be, quite literally, lost without.

We hear from New Orleanians who used Google Maps/Google Earth in its inaugural year to survey the damage to their homes following Hurricane Katrina.

We also talk to the internet's Map Men, who ask whether "the best maps humanity has ever produced are simultaneously the worst maps for humanity?" in their new book, "This Way Up: Whe...

There's a lot of drone warfare footage on the internet from Ukraine and Russia. But over the last year, a surprising change has emerged, via photos from the battlefront posted online. It has become clear that a huge part of the drone war, from dropping grenades on soldiers in bunkers, to dropping explosives on infrastructure or airfields, is wired. Those wires are fiber optic cable, stretching from drone operators to the drones, wh...

The internet decides what's for dinner.

Ruby Tandoh is the author of the new book, All Consuming: Why We Eat the Way We Eat Now. A stint on the Great British Bake Off when she was in college launched her into the world of cookbooks — increasingly irrelevant in a world where we're more likely to turn to Google for a recipe than turn to our bookshelves — and provided her an education in how pop culture stokes our cravings. She takes...

In honor of the day-after-Thanksgiving leftover sandwich, we're revisiting our conversation with Barry Enderwick, the man behind the beloved and wildly popular "Sandwiches of History" social media accounts.

First course: Chivegate, in which a Redditor vows to chop a cup of chives daily until the kitchen confidential subreddit declares perfection, only to be accused of fraud.  Second course: A Reddit user desperately seeking advice on how to quietly move 13 two-thousand-pound pallets of margarine.

The final episode of Hidden Levels explores the story of SEGA developer Tez Okano and the bizarre, meta-game he created: Segagaga.

Okano joined SEGA in 1992, witnessing firsthand the company's tumultuous experience in the "console wars" against Nintendo and Sony.

In the mid-1990s, SEGA struggled to make hardware that kept up with its rivals. The SEGA CD, the 32X, and the Saturn were all commercial failures. For Okano and many dev...

Video games are arguably the antithesis of nature; highly constructed worlds, synthetic, inorganic. If you grew up gaming, you may recall grown-ups telling you to shut down the console, go outside, and touch some grass.

These days, though, touching grass isn’t something you have to do outside. As gaming has grown into a 200 billion dollar industry, the boundary between screen and soil has muddied. New technologies and types of pla...

Dr. James "Butch" Rosser was a pioneer in minimally invasive surgery in the 1990s. When he credited his surgical skills to video games, people dismissed him. The prevailing narrative was that kids who played video games became killers, not doctors. So Butch set out on quest: to show how video games can help make better doctors.

Machinima — a portmanteau of “machine” and “cinema” — refers to movies filmed inside video games. The art form had a renaissance in the 1990s, and many thought it had a future in Hollywood. Among the early pioneers were the New York animation collective the Ill Clan, who puppeteered characters in real-time inside the video game Quake, bypassing traditional animation rendering. This technique exploded i...
