I tried the Galaxy Watch 8 AI running coach, and it left me humbled (but motivated)

Nina Raemont/ZDNET Within less than 24 hours of wearing Samsung's newest Galaxy Watch 8, I knew a trial run (pun intended) of Samsung's new Running Coach feature was in order. Running Coach is one of my most anticipated features in the Galaxy Watch 8 lineup, and does exactly what it sounds like: employs AI to calculate metrics like strain, pace, and recovery to improve your abilities and keep you on track for your next race. Also: Your Samsung Galaxy Watch is getting a big upgrade. Four featu

The best VPN services for iPhone in 2025: Expert tested and reviewed

Whether you've invested in the iPhone 16 or have a legacy device, it's important to consider using a virtual private network (VPN) to improve your online privacy. While all Apple iPhone models tend to have excellent connectivity, I always recommend using a VPN to keep your data safe. Trustworthy VPNs encrypt your online traffic when you access email, social media, and online services. If you have to rely on public Wi-Fi hotspots, they are excellent tools for protecting your data from digital ea

Best Amazon Fire TV Stick VPNs 2025: Expert tested and reviewed

Signing up for a virtual private network (VPN) that works with Amazon's Fire TV Stick has many benefits. You can circumvent app and smart TV operating system restrictions, change your IP location to appear to come from another country, and potentially explore more streaming content libraries than those usually available in your home region. Amazon Fire TV Stick VPNs are not all equal, however. Some VPNs excel in terms of speed and stability, while others focus on country and server selection, s

The best mobile VPNs of 2025: Expert tested and reviewed

NordVPN is a fast and reliable VPN with an extensive server network, regardless of what device you use, making it one of my favorite mobile VPNs. Why we like it: Once you've figured out NordVPN, there's no additional learning curve for using it on other devices. When you first open it, you'll see a landing screen map. From here, you can pick a country or head to the fastest local server automatically. If your screen's too small for that to be convenient, you're only a swipe away from a VPN ser

Largest piece of Mars on Earth fetches $5.3M at auction

The largest piece of Mars ever found on Earth was sold for just over $5 million at an auction of rare geological and archaeological objects in New York on Wednesday. But a rare young dinosaur skeleton stole the show when it fetched more than $30 million in a bidding frenzy. The 54-pound (25-kilogram) rock named NWA 16788 was discovered in the Sahara Desert in Niger by a meteorite hunter in November 2023, after having been blown off the surface of Mars by a massive asteroid strike and traveling

How to Migrate from OpenAI to Cerebrium for Cost-Predictable AI Inference

How To Migrate From OpenAI to Cerebrium for Cost-Predictable AI Inference If you're building an AI application, you probably started with OpenAI's convenient APIs. However, as your application scales, you'll need more control over costs, models, and infrastructure. Cerebrium is a serverless AI infrastructure platform that lets you run open-source models on dedicated hardware with predictable, time-based pricing instead of token-based billing. This guide will show you how to build a complete c

Show HN: A rudimentary game engine to build four dimensional VR evironments

Hypershack Hypershack is a standalone, private space designed for tinkering and learning with 4D objects in Virtual Reality. There are some elements designed to help get oriented in the 4d world: there are small particles falling down, i.e. moving towards negative y-axis. The speed they are falling depends on the orientation of the observed 3d space in the 4d world, the closer the 3d space is aligned with y-axis, the faster the particles fall. If you rotate the 3d space to be perpendicular to

Python Audio Processing with Pedalboard

Python audio processing with pedalboard The pedalboard library for Python is aimed at audio processing of various sorts, from converting between formats to adding audio effects. The maintainer of pedalboard , Peter Sobot, gave a talk about audio in Python at PyCon US 2025, which was held in Pittsburgh, Pennsylvania in May. He started from the basics of digital audio and then moved into working with pedalboard . There were, as might be guessed, audio examples in the talk, along with some visual

The .a File Is a Relic: Why Static Archives Were a Bad Idea All Along

From the perspective of an SDK provider, we must not limit our customers. As such, we are expected to provide both the dynamic linking option, as well as the static linking one. And what will this mean? Dynamic linking — Provide Shared Object ( .so ) libraries, as well as matching compilation ( .pc ) definitions. ) libraries, as well as matching compilation ( ) definitions.

How to Build a Functional Smart Home When You’ll Never Own a House Yourself

Ah, yes, the American dream. A house with a white picket fence, a dog, and as many products as you can pile into a pickup truck that you paid for in cash, which I’m told is a type of green paper you can exchange for goods and services. Sounds nice; sounds normal; sounds totally and completely out of reach. The classic American dream may be dead, but at least we have the Internet of Things and the never-ending font of smart home products it’s given rise to, right? I say that with my tongue ready

What Glasses Suit My Face: Shape, Skin Tone and More

Are you looking for new glasses during your annual glasses prescription and check-up, but aren't sure which frames truly suit you? You're not the only one. There are plenty of Reddit threads looking for advice on how to pick the right frames that truly complement your features.

Our guide is here to help by breaking down everything you need to know

Is Your Iced Coffee Making You Dehydrated in the Summer Heat? I Asked the Experts

As the summer sun beats down, we should all stay hydrated, as dehydration can increase our risk of heat exhaustion and heat stroke. However, when I saw the National Weather Service in Las Vegas advising residents across parts of California, Nevada and Arizona to stop drinking caffeine in extreme heat to prevent dehydration, I wondered if that was taking things too far. To find out whether caffeine actually causes dehydration to the point where you need to put your iced coffee down, I consulted

SAVE Student Loan Borrowers Have Less Than 2 Weeks Before Interest Restarts. Here's What to Do

Interest will restart for SAVE borrowers whose loans remain in a general forbearance on Aug. 1. Viva Tung/CNET If you're a student loan borrower enrolled in SAVE, you may feel pressured to switch to a new repayment before interest payments restart on Aug. 1. Although we know that you'll eventually have to move off this payment plan, you're not required to make any moves before August. In some cases, it might be better to remain in the general forbearance. Earlier this month, the Department of

Want a Fiber Internet Connection? Read This First

We write a lot about fiber internet at CNET. It's often touted as the "gold standard" of broadband by policymakers, experts and internet users alike. The Fiber Broadband Association estimates that a little over 76 million homes have made the switch to a fiber internet connection, representing a growth of 13% in the past year. If you've ever struggled with slow speeds or outages while using cable, 5G, satellite or (God forbid) DSL internet, you've probably considered switching internet providers

How to Recycle Your Old Computers and Printers for Free

It's weirdly difficult to get rid of old laptops, desktops and printers sitting around your house -- even when it's been over a decade since you last plugged them in. But recycling old tech is easier than you think and can free up a lot of space for you. A CNET survey found that 31% of US adults are still holding onto old, unused devices, including laptops, because they're unsure of what to do with them. The survey also found that 19% of respondents just toss old devices in the trash -- which i

This $20 Item Is the Thing I Buy First for My Kitchen When I Move

As a former girl scout I believe in always leaving a place better than I found it. As a food writer and former culinary school student, this entails always leaving behind a certain feature in any kitchen where I've lived. (As a former NYC resident, yes, there were numerous kitchens.) It's the first thing I buy for a new kitchen, without even needing to take measurements. Where I put it might be up for grabs, but it's guaranteed to be going somewhere. I'd sooner live without a microwave or a (*g

DOCSIS 3.0 vs. 3.1 vs. 4.0: How Are They Different?

If you have cable internet, then you're using DOCSIS technology. DOCSIS stands for Data Over Cable Service Interface Specifications, and it's a standard that defines how your modem relays cable internet signals to and from your home. If you have cable internet from Cox, Spectrum, Xfinity or a regional cable internet provider like Armstrong, you're using a DOCSIS-compliant modem. The DOCSIS 4.0 cable modem is ideal since it produces faster upload speeds. But while specifications for DOCSIS 4.0 h

Best Samsung Phone of 2025

If your family and friends are on Apple services like iMessage and FaceTime, stick with an iPhone. If you’ve been deep on Samsung, stay on Android. Know that switching between the two has never been easier. Phone makers promise varying lengths of long-term software and security support ranging from just one year to as many as seven. These updates not only ensure you get many of the latest features but also keep your phone secure. Phone cameras have gotten better over the past five years. Don’t

AT&T Promo Code: Get a Gift Card Worth Up to $200

Major wireless carriers: A necessary evil if you travel a lot, have a family, or are just interested in coverage that’s reliably consistent and widespread. AT&T is the third-largest provider in the US (first for 5G), with the largest coverage map. I’ve had various AT&T plans for more than a decade, first for just myself and now for my whole family, even though I only get one cell bar at my house and have to stand in one 5-square-foot patch of yard to make a phone call. And have lost entire days

Newly Discovered ‘Infinity Galaxy’ Could Prove How Ancient Supermassive Black Holes Formed

A team of astronomers have discovered a curious figure in the universe. It is two distant galaxies colliding with each other to form a larger structure. From Earth’s perspective, the junction of the disks resembles the number eight lying down, similar to the infinity symbol (∞). Because of this resemblance, the researchers—who are based at the universities of Yale and Copenhagen—have nicknamed it the “Infinity Galaxy” and have detailed their discovery in a paper published in the Astrophysical J

Did Tesla’s Robotaxi Launch Backfire?

Would you consider a ride in a self-driving car? After hearing a bit about Tesla’s robotaxi launch in Austin, Texas, last month, just under half of US consumers wouldn’t even think about it, according to survey data shared exclusively with WIRED. Thirty-one percent of the survey’s respondents said they’re not considering riding one right now. Sixty-five percent said they hadn’t even heard about Tesla’s robotaxi launch, which includes just a handful of cars and is open only to invited users—most

OpenAI’s ChatGPT Agent Is Haunting My Browser

Most people’s browser tabs are filled with unread news articles. Mine are filled with AI agents and ghost clicks. I have four instances of OpenAI’s ChatGPT Agent—the generative AI tool released last week, which can run searches and perform tasks on the web—already open with each running in its own tab. I’ve given these first four agents relatively simple jobs based on ChatGPT’s suggestions. One is clicking around to find a birthday gift on the Target website, and another is generating a pitch d

How to Spot and Guard Against Wrong Number Scams

Something you can be sure of when it comes to scams and swindles is that the methods used to try to part you from your data, your money, or both are constantly changing—which of course makes it more difficult to spot scenarios where someone is attempting to trick you. One simple scam that's continuing to get more common starts off with text from someone who has apparently messaged the wrong number. There's no mistake though: Your number is being deliberately targeted by a fraudster. A wrong nu

X Data Center Fire in Oregon Started Inside Power Cabinet, Authorities Say

A recent, hours-long fire at a data center used by Elon Musk’s X may have begun after an electrical or mechanical issue in a power system, according to an official fire investigation. WIRED was the first to report on the blaze, which occurred on May 22 in Hillsboro, Oregon. Data center giant Digital Realty operates the 13-acre site, and multiple people familiar with the matter previously told WIRED that the Musk-run social platform X has servers there. Data center fires are rare, with about tw

Fiberglass-Free, Chemical-Free: Natural Fire Barriers for Mattresses

What do mattresses and a box of matches have in common? It's not just that they’re both rectangular—both can can be very flammable if you're not careful. Mattresses have historically posed a significant fire hazard, and they still can without careful attention to the materials used. In the US, an estimated 20,800 residential fires occurred due to mattresses and bedding igniting from flame exposure between 1996 and 1998, according to FEMA. At that time, fires involving mattresses and bedding wer

Tesla opens retro-futuristic diner as Elon Musk hints at more locations

In Brief The Tesla Diner & Drive-In, a long-awaited and hyped facility that combines retro nostalgia and futurism with the automaker’s fast-charging network, officially opened at 4:20 p.m. on Monday in Hollywood, California. The Tesla Diner & Drive-In is technically a place for Tesla drivers to charge their EVs and maybe get hamburgers, hot dogs, or other classic diner menu items (which Eater shared in full). The diner, according to Not a Tesla App, is loaded with Tesla-branded merchandise, an

Instead of selling to Meta, AI chip startup FuriosaAI signed a huge customer

South Korean AI chip startup FuriosaAI announced a partnership on Tuesday to supply its AI chip, RNGD, to enterprises using LG AI Research‘s recently unveiled EXAONE platform. RNGD is optimized for running large language models (LLMs) and just last week, the Korean tech giant LG unveiled its next-generation hybrid AI model EXAONE 4.0.

Google Store starts teasing Pixel 10 series with a full-blown reveal!

Google TL;DR Google has scheduled its next Made by Google hardware event for August 20. The company is expected to introduce the Pixel 10 series, Pixel Watch 4, and maybe even some new Pixel Buds.
