Fitbit promised better sleep tracking with new update, but users say it got worse

androidauthority.com Unknown 2025-12-22 22:54:01

Kaitlyn Cimino / Android Authority TL;DR Fitbit has updated its algorithm for more accurate sleep tracking. The new algorithm now accounts for awake times better, supposedly rendering more accurate data about different phases. However, users have complained of increased sensitivity, resulting in their devices capturing shorter sleep durations than the actual time. Fitbit isn’t nearly as popular as it once was, and that is partly because Google, which completed its acquisition of the company

Ryan Whitwam / Android Authority TL;DR The Samsung Galaxy Tab S11 Ultra has passed by the website of China’s 3C regulatory body. The listing reveals that Samsung’s upcoming tablet will have 45W charging, in line with last year’s model. A Samsung executive previously confirmed that the Galaxy Tab S11 series was in the works.

New world record Weather satellites detect 515-mile-long lightning flash

news.ycombinator.com Stefanie Waldek 2025-12-19 15:10:28

Some areas are more prone to lightning storms than others. It's 2017, and a thunderstorm shoots off a lightning bolt. What's so special about that, you ask? Well, the bolt is an astonishing 515 miles (829 kilometers) long. Using archival satellite data, researchers just officially confirmed the length of this enormous bolt of lightning that stretched from Texas to Missouri. It sets a new world record, besting the previous title holder — a 477-mile (768-km) bolt from 2020 — by 38 miles (61 km).

How Supercomputing Will Evolve, According to Jack Dongarra

Quantum computing is interesting. It’s really a wonderful area for research, but my feeling is we have a long way to go. Today we have examples of quantum computers—hardware always arrives before software—but those examples are very primitive. With a digital computer, we think of doing a computation and getting an answer. The quantum computer is instead going to give us a probability distribution of where the answer is, and you’re going to make a number of, we’ll call it runs on the quantum comp

This Forgotten '90s Cyberpunk Flick Nailed the Dystopian VR Vibes

Pull up any list of the ultimate cyberpunk movies and you'll find The Matrix, Blade Runner and Ghost in the Shell. But there's one great tech noir flick that came out at the height of the cyberpunk craze -- and then all-but disappeared. Maybe that's partly because of its title. I'd wanted to rewatch Strange Days for a long time, but I kept forgetting because, honestly, I couldn't remember what it was called. Then I finally rediscovered the sci-fi thriller on Hulu.

The Galaxy S26 Edge battery rumors just got even more promising

Both leaks point to Samsung addressing one of the biggest complaints about the S25 Edge. The Galaxy S25 Edge was one of Samsung’s most criticized flagships of recent years, and much of that frustration rightly centered on battery life.
