The Whoop 5.0 Is a Massive Upgrade to Health Tracking. I Wasn’t Ready.

gizmodo.com Claire Maldarelli 2025-08-07 03:00:24

At some point in the late 2010s, I became obsessed with my heart rate. I was at a point in my fitness life that I was training for marathons and I cared a whole lot about every process involved. I spent a certain percentage of my workday staring at my heart rate on my fitness watch and feeling smug if I kept my resting heart rate below 50 beats per minute (bpm) and wigging out if it went over 60 bpm. Heart rate was my gateway drug into health tracking, and it soon devolved into an unhinged compu

The Fantastic Four Were Too OP For the Infinity Saga

gizmodo.com Justin Carter 2025-08-07 04:30:34

One of the big draws of next week’s Fantastic Four: First Steps is seeing Marvel’s First Family in the retrofuturist Earth-828. They’re Earth’s only heroes in that dimension, and before Galactus shows up, it sounds like they’ve done a pretty good job protecting the planet. They might even be too good at it, which is why they’re in their own universe to begin with. During a recent MovieWeb interview, director Matt Shakman discussed how the Four were made “in this time of optimism during the spac

Microsoft is moving closer to a password-free future, and if you're still using the Authenticator app to manage logins, big changes are coming fast. Starting Aug. 1, the app will no longer support passwords at all. This shift has already been in motion-new password creation was disabled in June, and autofill support was cut off in July. For years, Microsoft Authenticator was a go-to for managing both multi-factor authentication and saved passwords. But now, it's being refocused to support passk

Here's How to Turn Off Some Annoying iPhone Texting Features

Texting is one of the easiest ways to stay in touch with friends and family, and if you can't find the right words to use in a text, you can always use an emoji. But you might find some texting features on iPhone to be downright annoying. Some of the biggest culprits include autocorrect and predictive texting. Autocorrect can cut down on the number of typos when you're typing, and predictive texting can make it easy to write a full message in a few quick taps. But when I use these features, mor

A new Martian climate model suggest a mostly cold, harsh environment

arstechnica.com Unknown 2025-08-07 01:13:05

The Curiosity rover was sent up the Mount Sharp, the biggest sediments stack on Mars. On the way, it collected samples that indicated a portion of carbon dioxide in the Martian atmosphere might have been sequestered in the sedimentary rocks, just as it happens with limestone on Earth. This would have drawn carbon dioxide out of the atmosphere, reducing the greenhouse effect that warmed the planet. Based on these findings, a team of scientists led by Benjamin Tutolo, a researcher at the Universi

For Algorithms, Memory Is a Far More Powerful Resource Than Time

wired.com Ben Brubaker 2025-08-07 01:00:00

That classic result was a way to transform any algorithm with a given time budget into a new algorithm with a slightly smaller space budget. Williams saw that a simulation based on squishy pebbles would make the new algorithm’s space usage much smaller—roughly equal to the square root of the original algorithm’s time budget. That new space-efficient algorithm would also be much slower, so the simulation was not likely to have practical applications. But from a theoretical point of view, it was n

The upcoming GPT-3 moment for RL Matthew Barnett, Tamay Besiroglu, Ege Erdil Jun 20, 2025 GPT-3 showed that simply scaling up language models unlocks powerful, task-agnostic, few-shot performance, often outperforming carefully fine-tuned models.

Hill Space: Neural nets that do perfect arithmetic (to 10⁻¹⁶ precision)

When understood and used properly, the constraint W = tanh(Ŵ) ⊙ σ(M̂) (introduced in NALU by Trask et al. 2018 ) creates a unique parameter topology where optimal weights for discrete operations can be calculated rather than learned . During training, they're able to converge with extreme speed and reliability towards the optimal solution. Most neural networks struggle with basic arithmetic. They approximate, they fail on extrapolation, and they're inconsistent. But what if there was a way to m
