Twitter cofounder Jack Dorsey is back with a new app that tracks sun exposure and vitamin D levels.
Sun Day uses location-based data to show the current UV index, the day’s high, and additional details like cloud cover, sunrise, and sunset times. Users can choose their skin type from six options and indicate their clothing, such as “light (shorts & t-shirt)”, then manually toggle when they’re in or out of the sun.
Based on this input, the app calculates how lo
Under the ocean’s surface lies the true backbone of the internet: an estimated 870,000 miles of submarine cables that ferry over 95% of global intercontinental data traffic across every major ocean. These cables are critical infrastructure, carrying everything from our daily video calls to mul
AI chatbot therapists have made plenty of headlines in recent months—some positive, some not so much.
A new paper from researchers at Stanford University has evaluated five chatbots designed to offer accessible therapy, using criteria based on what makes a good human therapist. Nick Haber, an assistant professor
The latest version of Elon Musk’s artificial intelligence chatbot Grok is echoing the views of its billionaire creator, so much so that it will sometimes search online for Musk’s stance on an issue before offering up an opinion.
The unusual behavior of
A gleaming Belle from Beauty and the Beast glided along the exhibition floor at last year’s San Diego Comic-Con adorned in a yellow corseted gown with cascading satin folds. She could barely take two steps before a cluster of little girls stopped her for photos. As she waved one hand, her other delicately held a red flower with mechanized fingers. The kids stared. It’s not every day you see a fairy-tale princess with a cybernetic hand. Disney meets Skynet. But this being the epicente
The internet wasn’t born whole—it came together from parts. Most know of ARPANET, the internet’s most famous precursor, but it was always limited strictly to government use. It was NSFNET that brought many networks together, and the internet that we use today is almost NSFNET itself.
Almost, but not quite: in 1995, the government that had raised the internet from its infancy gave it a firm shove out the door. Call it a graduation, or a coming of age. I think of it as the internet g
Computing revolutions are surprisingly rare. Despite the extraordinary technological progress that separates the first general-purpose digital computer—1945’s ENIAC—from the smartphone in your pocket, both machines actually work the same fundamental way: by boiling down every task into a simple mathematical system of ones and zeros. For decades, so did every other computing device on the planet.

Closed, it looks pretty much like any other laptop manufactured in 1995.
To be sure, it’s more compact than most—making it, in the parlance of the day, a subnotebook. But it’s still comically thick, standing almost as tall as four MacBook Airs stacked on each other. That height is required to accommodate multiple technologies later rendered obsolete by technological progress, such as a dial-up fax/modem, an infrared port, two PCMCIA expansion card slots, and a bulky connector for a
