SteelSeries Rival 3 Gen 2 Review: Good Budget Gaming Mice

Over the years, computer mice have become expensive. Everything has become expensive. It can be frustrating to look at a list of gaming mice and see even the cheapest options approaching $80, especially when games now cost $80 and new graphics cards regularly pass the $1,000 mark. This is where budget-oriented mice are perfect. Most high-end mice are past the point of diminishing returns for the average gamer, with most never needing the precision of a perfectly balanced, ultra-lightweight, 8,0

Elon Musk, during a news conference with President Donald Trump, inside the Oval Office at the White House in Washington on May 30, 2025. Tesla shares fell 6% in premarket trading on Thursday after the company reported a second straight quarter of declining automotive sales. Elon Musk's electric carmaker reported a top and bottom line miss on second-quarter results, noting that automotive revenue fell 16% year-on-year to $16.7 billion. On an earnings call, Musk said Tesla "probably could have

Qi2 25W wireless charging is coming to iPhones and 'major Android smartphones'

The newest version of the Qi2 wireless standard is coming to iPhones and some Android handsets. It has also received a snappy, new branding of Qi2 25W, denoting the wireless charging speed, which is miles better than the previous name of Qi2.2. The big hook here is right in the name. Qi2 25W provides up to 25 watts of power delivery to compatible products, which is a 66 percent increase over the pre-existing Qi2 platform. Paul Struhsaker, Executive Director of the Wireless Power Consortium (WPC

ChatGPT is rolling out 'personality' toggles to become your assistant

OpenAI is rolling out a new "personality" feature on the ChatGPT web app. This allows you to choose between multiple personalities, such as "Robot." ChatGPT is pretty good at coding and reasoning, but it falls a bit short on personality. On the other hand, Microsoft Copilot feels a bit more personal, but that could change soon. With the personality feature, which is slowly rolling out to some users across the world, you can personalize how ChatGPT interacts with you. By default, ChatGPT is ch

The best Xbox controller to buy right now

We live in a golden age of controllers. The gamepads on the market now are of higher quality, more versatile, and more customizable than anything from even one console generation ago. If you play games on an Xbox Series X or Series S (or a Windows PC), you have the unenviable task of choosing between several high-quality controllers from Microsoft as well as a plethora of great options from the likes of 8BitDo, PowerA, Razer, Scuf, Nacon, and Turtle Beach. Some of them have drift-proof Hall effe

GM Re‑Embraces Gas Cars as EV Dream Hits a Major Pothole

The electric vehicle revolution just got a harsh reality check. General Motors is tapping the brakes on its all-electric push, signaling that the gasoline-powered cars we’ve known for a century have a much “longer runway” than previously predicted. This marks a strategic pivot that speaks volumes about the cooling EV market. The shift in tone and strategy was laid bare during the company’s second-quarter conference call with analysts Tuesday, where executives announced plans to increase product

How to turn off ACR on your TV (and why you shouldn't wait to do it)

Adam Breeden/ZDNET Did you know that whenever you turn on your smart TV, you invite an unseen guest to watch it with you? These days, most popular TV models utilize automatic content recognition (ACR), a form of ad surveillance technology that gathers information about everything you watch and transmits it to a centralized database. Manufacturers then use your data to identify your viewing preferences, enabling them to deliver highly targeted ads. Also: Your TV's USB port is seriously underut

Google just released a convenient way to clean up Call Notes on your Pixel

Google TL;DR Google has started rolling out an auto-delete feature to Call Notes on Pixel 9 phones. This feature lets you automatically delete Call Notes after a specified period of time. The news comes a few months after we first discovered evidence of this option. Google revealed a Call Notes feature alongside the Pixel 9 series last year. This feature records, transcribes, and summarizes phone calls. We’ve seen evidence that Google could bring an auto-delete feature to Call Notes, and it’

Splitgate 2 is yanked back to beta a month after release

Splitgate 2, the follow-up to the hugely successful 2021 Quake-Portal hybrid concept, is returning to beta. The game launched last month, but developer 1047 Games is pulling it after deciding the release had been rushed. The company doesn't plan to release the project again until 2026. "We'll be heads down until early next year, rebuilding major parts of the game to capture the spirit of what made Splitgate special," the founders said in a post to the game's Reddit community. "That means rework

How to Check If That ‘Deleted’ Tweet Is Real

It happens almost every day. A screenshot of a social media post from a prominent figure like Elon Musk or Donald Trump goes viral because it demonstrates just how stupid these men really are. But sometimes it sounds too good to be true. You go to check X or Truth Social yourself and it’s not there. But maybe it was deleted. What do you do? Well, we’ve got some tips that might be helpful for uncovering the truth. Right off the bat, it’s important to note that there’s not always a foolproof way

Telegram's crypto wallet goes live to its 87 million U.S. users

Telegram users in the U.S. can now send, receive, and manage cryptocurrency directly inside the app — no downloads, extensions, or separate logins required. TON Wallet is built into Telegram's interface and is beginning its U.S. rollout this week. It is a self-custodial crypto wallet in which a user controls their own private keys. The service, developed by The Open Platform, which is known as TOP, and built on the TON blockchain, allows users to send stablecoins and other digital tokens to th

I know genomes and I didn’t delete my data from 23andMe

As word spread last year that 23andMe was about to go bankrupt, many of their millions of customers wondered if they should delete their data. Social and conventional media were quick to offer advice, sometimes coming from experts in genetics and genomics–my field, I should note–on how to go onto the 23andMe website and delete all of your data. In March of this year, the California attorney general issued a warning that 23andMe was “in financial distress,” and he told Californians that they oug

Telegram’s crypto wallet launches in the US

Telegram is expanding access to its crypto wallet for its 87 million users in the U.S. The TON wallet, named because it is built on the TON blockchain, is integrated directly into the Telegram app. By existing within the app, Telegram’s crypto wallet is supposed to form an easier onramp for new crypto users. Telegram has offered crypto wallets to international users since 2023, though it was unable to roll out in the US until now due to regulatory uncertainty. Telegram says more than 100 milli

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

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

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

The iPhone 17 Could Be Revealed in Less Than Two Months. Here's What Date to Expect It

Anticipation is growing as the release of the rumored iPhone 17 draws near, but recent speculation about the release date offers us a glimpse into when we'll learn everything about the new iPhone. In his Power On newsletter on July 13, Bloomberg's Mark Gurman said that the announcement should come Sept. 9 or 10. That generally aligns with CNET Senior Editor Patrick Holland's prediction, based on his assessment of Apple's past announcements and a decade of reviewing mobile phones. We'll get more

FCC to eliminate gigabit speed goal and scrap analysis of broadband prices

The Federal Communications Commission is ditching Biden-era standards for measuring progress toward the goal of universal broadband deployment. The changes will make it easier for the FCC to give the broadband industry a passing grade in an annual progress report. FCC Chairman Brendan Carr's proposal would give the industry a thumbs-up even if it falls short of 100 percent deployment, eliminate a long-term goal of gigabit broadband speeds, and abandon a new effort to track the affordability of

Flickering lights? Blown breakers? Your home needs more power - here's what to do

PM Images/Getty The hair dryer routinely trips the breaker and kills power to the second floor. The kitchen lights dim when you run the microwave. The air conditioner can only cool one room at a time on a sweltering night. You don't have adequate power in your house to support your daily needs; we've all been there. These examples might be nostalgic for some, but if you can relate in your current living situation, you might be stuck at a CORE level 1 power-constrained state. Beyond the inconv

Jqfmt like gofmt, but for jq

Description I'm frequently passed long shell one-liners that require some visual inspection before running. These days, there's about as much jq in that one-liner as there is bash. I wrote jqfmt to help add line breaks in sensible locations while reading (or writing!) jq. At time of initial development, I naturally turned to https://github.com/itchyny/gojq expecting to be able to generate and walk a syntax tree—but gojq didn't seem to provide an AST that could be "walked," and it doesn't expor

Using the Matrix Cores of AMD RDNA 4 architecture GPUs

AMD RDNA 4 architecture GPUs AMD RDNA™ 4 architecture GPUs, which have 3rd-generation Matrix Cores, improved the performance of Generalized Matrix Multiplication (GEMM) operations. The table below compares theoretical FLOPS/clock/CU (floating point operations per clock, per compute unit) to previous generations. However, we changed the VGPR layout for the arguments of Wave Matrix Multiply Accumulate (WMMA) operations compared to the previous RDNA 3 generation [1]. Therefore, it does not have ba

New colors without shooting lasers into your eyes

1. Your eyes sense color. They do this because you have three different kinds of cone cells on your retinas, which are sensitive to different wavelengths of light. For whatever reason, evolution decided those wavelengths should be overlapping. For example, M cones are most sensitive to 535 nm light, while L cones are most sensitive to 560 nm light. But M cones are still stimulated quite a lot by 560 nm light—around 80% of maximum. This means you never (normally) get to experience having just o

James Webb Spots Planets Forming Into Solar System in Real Time, Like an Organism's First Cells

Astronomers have spotted a planetary system being conceived from the swirl of gas and dust surrounding a star — giving us an unprecedented, real-time look at how our solar system would've formed some 4.6 billion years ago. The findings, published as a study in the journal Nature, are the first time we're seeing such an early stage of planets being formed anywhere in the cosmos. "We've captured a direct glimpse of the hot region where rocky planets like Earth are born around young protostars,"

Android 16 is a mess right now

Joe Maring / Android Authority If you’re reading this article, chances are you love Android. Or, at the very least, have a fairly high interest in the OS. You probably like staying up-to-date with the latest features, new platform releases, and other happenings with Google’s operating system.

And this past week, Google just made it all the more obscure with the release of Android

A CarFax for Used PCs: Hewlett Packard wants to give old laptops new life

The United Nations’ Global E-waste Monitor estimates that the world generates over 60 million tonnes of e-waste annually. Furthermore, this number is rising five times as fast as e-waste recycling. Much of this waste comes from prematurely discarded electronic devices. Many enterprises follow a standard three-year replacement cycle, assuming older computers are inefficient. However, many of these devices are still functional and could perform well with minor upgrades or maintenance. The issue i

Why It’s Taking LA So Long to Rebuild After the Wildfires

This story originally appeared on Vox and is part of the Climate Desk collaboration. In the wake of the record-breaking wildfires in Los Angeles in January—some of the most expensive and destructive blazes in history—one of the first things California governor Gavin Newsom did was to sign an executive order suspending environmental rules around rebuilding. The idea was that by waiving permitting regulations and reviews under the California Coastal Act and the California Environmental Quality A
