The 177 best Prime Day 2025 deals that we found

Prime Day , Amazon’s four-day thunderdome of exclusive deals, is here. Outside of Black Friday and Cyber Monday, we anticipate this to be the best moment of the year to score discounts on headphones, laptops, TVs, gaming gear, and really anything else that might be on your wishlist — or someone else’s. We sorted through thousands of deals, ultimately narrowing it down to including products we’ve tried (many of which we’ve reviewed) and can vouch for. To repeat, there will be four — count ’em —

macOS Tahoe: Reports of FireWire’s death not greatly exaggerated

How dead is FireWire support in macOS Tahoe 26? As dead as the iPod, as far as the Mac is concerned, which is at least a little sad. Stephen Hackett checked. In classic 512 Pixels fashion, he’s conjured together a real world demonstration using a battle-tested FireWire 800 cable-connected drive, two Thunderbolt adapters including a Thunderbolt 2 to 3 dongle, and a Mac. Woof. The result? A drive that correctly appeared as several volumes on macOS Sequoia just looks like an adapter to nowhere on

Following hiccup, macOS Tahoe 26 developer beta 3 is now available for Apple Silicon Macs

Earlier today, Apple released its new set of developer betas, but a distribution issue affected the Apple Silicon version of macOS Tahoe 26 developer beta 3. Now, the issue seems to have been resolved, and the update is now available for all compatible Macs. What happened? Users on X claimed that the hiccup involved Rosetta 26 beta 3, a required component for running Intel apps on Apple Silicon. Apple didn’t confirm the issue, but whatever the problem might have been, it seems to have been sol

Denis Villeneuve Will Shoot All of ‘Dune Messiah’ in IMAX

Dune: Part Two was masterful on its own, but in IMAX, it was truly breathtaking. When director Denis Villeneuve opened his aspect ratio up to the full screen 1:43:1 for scenes such as Paul riding the sandworm, it was like traveling from the theater to Arrakis itself. So, it’s no surprise that, hot on the heels of Christopher Nolan’s The Odyssey becoming the first ever Hollywood feature to be filmed entirely with full-screen IMAX 70mm-capable film cameras, we now know the second film to achieve t

Tulum Energy rediscovered a forgotten hydrogen tech and used it to raise $27M

It was a mistake that was ahead of its time. Between 2002 and 2005, engineers with the Techint Group were trying to dial in a new electric arc furnace for a steelmaker when they noticed something odd. The carbon electrodes, rather than breaking down, were growing larger. The team had inadvertently created what’s known as a pyrolysis reaction, which is basically burning something in the absence of oxygen. In this case, the furnace was splitting methane into pure hydrogen and pure carbon. The te

LookingGlass: Generative Anamorphoses via Laplacian Pyramid Warping

Anamorphosis refers to a category of images that are intentionally distorted, making them unrecognizable when viewed directly. Their true form only reveals itself when seen from a specific viewpoint, which can be through some catadioptric device like a mirror or a lens. While the construction of these mathematical devices can be traced back to as early as the 17th century, they are only interpretable when viewed from a specific vantage point and tend to lose meaning when seen normally. In this p

Waymo robotaxis are heading to Philadelphia and NYC

Waymo kicked off two “road trips” to Philadelphia and New York City on Monday, signaling the Alphabet-owned company’s interest in expanding into Northeastern cities. Waymo’s branded “road trips” don’t necessarily signal a commercial launch anytime soon. Waymo has announced several other road trips this year, including to Houston, Orlando, Las Vegas, San Diego, and San Antonio. Typically, the trips involve sending a small fleet of human-driven vehicles equipped with Waymo’s autonomous driving sy

Show HN: I Got Tired of Calculator Sites, So I Built My Own

I’ve always found that online calculators tend to have bad UIs, especially on mobile. Most of the calculator websites I’ve come across use outdated and inconvenient ways of inputting data, or they format the results in confusing ways. I’ve noticed that fraction calculators (especially mixed fractions) are terrible to use, even on desktop. I haven’t built one of those yet, but it’s something I’m planning to tackle soon. This is a project I’ve always wanted to work on, but I’m relatively new to

This 1-Year Sam’s Club Membership (Auto-Renew) Drops to Nearly Free, a Cheap Alternative If Costco Is Too Far

Life is pretty darn expensive. In fact, it’s getting pricier by the day at the moment, at least for a lot of us, and that means that it’s really important to find ways to not only save money on luxuries that help keep us all sane, but also on daily essentials. That can be a lot harder to do though, but there are some really easy ways to get those savings going, and one of those is with a good warehouse membership. See at StackSocial Sam’s Club is a membership-only retailer that stocks a huge n

GM’s Cruise Cars Are Back on the Road in 3 US States—but Not for Ride-Hailing

Cruise robotaxis are back on the road … well, kind of. Though General Motors pulled the plug on its self-driving taxi business last year, the automaker has been quietly repurposing a few of the vehicles as it seeks to develop new driver-assistance technologies. This week, WIRED spotted a GM Bolt electric hatchback on the San Francisco–Oakland Bay Bridge and later saw a similar vehicle on Interstate 880 near Oakland. In each instance, the car was being driven by a human. But it held equipment on

Tesla loses $68 billion in value after Elon Musk says he is launching a political party

Now the tech billionaire's reinvolvement in the political arena is making investors nervous. The billionaire's involvement in politics has been a point of contention for investors. Musk earlier this year was instrumental in the so-called Department of Government Efficiency and worked closely with President Donald Trump — a move seen as potentially hurting Tesla's brand . Musk said Saturday that the party would be called the "America Party" and could focus "on just 2 or 3 Senate seats and 8 to

Ancient skull may have been half human, half Neanderthal child

Back in 1929, archaeologists unearthed several human skeletons (seven adults and three children) while excavating Skuhl Cave just south of Haifa, Israel. Dating back 140,000 years to the end of the Middle Pleistocene, most were classified as early Homo sapiens. But one skeleton was that of a child, between the age of 3 and 5 years old whose features seemed to show a mix of early human and Neanderthal characteristics. A new analysis involving CT scanning may resolve the long-standing debate, acco

Drive Capital’s second act — how the Columbus venture firm found success after a split

The venture capital world has always had a hot-and-cold relationship with the Midwest. Investors rush in during boom times, then retreat to the coasts when markets turn sour. For Columbus, Ohio-based Drive Capital, this cycle of attention and disinterest played out against the backdrop of its own internal upheaval several years ago — a co-founder split that could have ended the firm but may have ultimately strengthened it. At a minimum, Drive achieved something newsworthy in today’s venture lan

Everything you want to know about the Galaxy Z Fold 7, Flip 7, and Flip 7 FE just leaked

Hadlee Simons / Android Authority TL;DR Specs for the Galaxy Z Fold 7, Flip 7, and Flip 7 FE have leaked. The information reportedly comes from official Samsung promotional materials. The company’s foldables appear to sport disappointingly small batteries. Samsung is set to reveal its latest foldables at Galaxy Unpacked this week. While the showcase is scheduled for June 9, it doesn’t look like you’ll have to wait until Wednesday to learn more about the company’s new hardware. Some leaked pr

Tyr, a new Rust DRM driver targeting CSF-based ARM Mali GPUs

The last year has seen substantial progress on the DRM infrastructure required to write GPU drivers in Rust. While a great part of it was fueled by the development of Nova (the new driver for GSP-based NVIDIA GPUs), and by AGX (the driver for the GPUs on Apple's M-series chip that preceded Nova), a few components were being worked on to cater to a then undisclosed driver that was being prototyped behind the scenes. A driver that we now introduce to the community at large in a very early stage.

On Monday, Bluesky announced three updates to enhance notifications, allowing users to personalize their experience while decluttering their notification center and reducing unnecessary alerts. The updates include the ability to receive activity notifications for specific accounts, as well as options to adjust notification preferences to control which alerts you receive. For instance, users can choose to be notified only when certain accounts reply to them. Bluesky users can now navigate to Se

Gemini’s new overlay is getting ready to bounce onto your screen (APK teardown)

AssembleDebug / Android Authority TL;DR Google’s currently working on a number of visual changes to how you interact with the Gemini overlay. In addition to updating the coloring and shape of the overlay, we’ve identified a new animation it could use to appear on screen. We can trigger this effect both when accessing the overlay via swiping, as well as long-pressing the power button. Google continues to make the case for Gemini in — well, pretty much everything — and little by little it’s be

The Chinese EV Carmaker That Is Quietly Crushing Tesla

While Tesla’s struggles dominate the headlines, a quieter but more significant story is unfolding: Chinese electric vehicle makers are on a tear. For the second consecutive quarter, Elon Musk’s Tesla has seen its sales decline, a stark contrast to the booming growth reported by rivals like BYD and NIO Inc, who are steadily gaining market share and widening their lead. The second-quarter sales numbers paint a bleak picture for the American EV pioneer. Tesla delivered 384,122 vehicles worldwide,

Zillow Lists the Fantastic Four’s Home for a Surprisingly Low Price

Few sites on the internet can be as fun, or frustrating, to cruise as Zillow. It’s the place to see how impossible it is to afford your dream home and also see how far a dollar can go in places you don’t live. However, it seems in whatever time and dimension the Fantastic Four live in, the dollar goes a long, long way, even in one of the priciest real estate markets of all, New York City. Marvel has teamed up with Zillow for a very fun piece of marketing where the Baxter Building, home to the F

The 8 Best Travel Pillows (2025), Tested on Planes

I’m sorry, but I find this travel pillow hideous. It’s just so big and dorky. But damn if it isn’t effective. It’s actually really comfortable. It’s sort of like a scarf that you wrap around your neck, with a built-in frame that cradles your head securely and comfortably. The scarf part is nice and made of soft fleece, similar to other travel scarves or blankets. The hook-and-loop attachment point isn’t too loud when you adjust it, so you won’t disturb your neighbors. The Trtl comes in a few col

Nintendo wants to keep ‘traditional approach’ to development as costs skyrocket

A bigger, more powerful Switch means bigger, more intensive games that take more time and money to make. But as development costs skyrocket across the industry, Nintendo seems to have a plan to keep things in control as it transitions into the Switch 2 era. In response to a question during a recent shareholders meeting about the increased costs of making games for its new console, Nintendo president Shuntaro Furukawa admitted that “recent game software development has become larger in scale and

Best Window Air Conditioners 2025: 10 Picks to Cool You for Years

The EcoFlow Wave 3 is not for the weak. I mean that literally, as it weighs nearly 56 pounds when attached to its 22-pound lithium battery. At 6,100 BTU cooling capacity, the Wave 3 is designed for a car, RV, tent, boat, or any space that might be either temporary or off the grid. The Wave 3 also has a slightly higher 6,800 BTU heat mode. I have a van and and a dog, so for me, the Wave 3 offers a specific type of assurance on hot or cold days. Portable doesn’t mean you can move it around a lot.

CoreWeave acquires data center provider Core Scientific in $9B stock deal

In Brief CoreWeave announced Monday that it signed a $9 billion all-stock deal to acquire Core Scientific, a data center infrastructure provider. As a result of the deal, CoreWeave says it will gain access to more than a gigawatt of data center capacity — enough energy to power more than 850,000 homes — that it can rent out for AI training and inference workloads. Much like CoreWeave, Core Scientific previously offered Bitcoin mining services, but now its GPUs will run and train generative AI

SUS Lang: The SUS Hardware Description Language

The compiler keeps track of many aspects of your hardware design, and displays them in the editor. Core Philosophy The SUS HDL is meant to be a direct competitor to Synthesizeable Verilog and VHDL. Its main goal is to be an intuitive and thin syntax for building netlists, such that traditional synthesis tools can still be used to analyze the resulting hardware. SUS shall impose no paradigm on the hardware designer, such as requiring specific communication protocols or iteration constructs. In

Tesla Is Losing the EV War to Chinese Carmakers
