During my years as a TechRadar Homes Editor, I tested an awful lot of vacuums. But the one that's been my constant companion throughout has been the Dyson V15 Detect . It's not a review sample — my partner bought it, and it's the vacuum we've been using at home for the past 21-plus months. It's been used to clean hard tile floors, carpets, lots of stairs, and a whole heap of dog hair. The V15 is not the newest Dyson vacuum. It came out in 2021 and there are now two newer flagship models: the Gen5detect (launched 2022) and the V16 Piston Animal (2025). However, despite not being the latest-and-greatest, it's still the model that sits atop our best Dyson vacuum guide . So after nearly two years of regular cleaning with the V15, would I still recommend it? How does it match up against the rest of the best cordless vacuums on the market — and specifically, the newest models...

The Samsung Galaxy Z Fold 8 is smaller, cheaper, and has fewer cameras than the Galaxy Z Fold 8 Ultra, but it may end up being the most popular Galaxy foldable to date. Why? Because its 7.6-inch inner screen has a 4:3 aspect ratio, which is supposedly “the new standard for viewing content,” as Samsung told us in an interview — and if there’s one thing most of us can’t get enough of in 2026, it’s content. The Galaxy Z Fold 8 Ultra, meanwhile, has an eight-inch inner screen with a 10:9 aspect ratio, which is great for spreadsheets and multitasking, but less brilliant for movies and YouTube videos. Don’t believe me (or Samsung)? I compared the experience of streaming Netflix, watching YouTube, and scrolling through Instagram Reels on the Galaxy Z Fold 8 and Galaxy Z Fold 8 Ultra — in both portrait and landscape orientations, where possible — to help you visualize the aspect ratio differences betwee...

Meta rebuilt storage systems after slow data repeatedly stalled expensive AI GPUs SSD caching dramatically reduced AI dataset loading times from hours to minutes Meta replaced complex metadata lookups with a faster unified storage architecture Meta says storage systems have failed to keep pace with AI computing power, creating delays that leave costly GPUs waiting instead of processing workloads efficiently. According to the company's engineers, storage bottlenecks remain a major cause of GPU stalls, increasing operating costs while slowing research progress and extending development timelines. To address those delays, Meta redesigned its storage architecture, arguing that faster movement of data can unlock greater value from expensive AI hardware investments. Meta rebuilds storage architecture to keep GPUs working Meta's engineers explained that the company operates hundreds of exabyte-...

When Sony announced that it would no longer be producing physical PlayStation discs from 2028, the response was not positive, to put it lightly. Yes, PC gaming may now be almost entirely digital, and things have certainly been moving in a similar direction with consoles over the last few years, but ceasing production of physical games entirely? It’s a significant step many didn’t want to happen so soon. PlayStation fans have been vocal in calling out the negatives of Sony’s decision, specifically what this means for game ownership, preservation, and collectors who enjoy buying physical. The company has been reticent to address the backlash, but the comments section of every blog entry, social media post, or trailer release since the announcement is full of anger, pleas to reverse the decision, and glib remarks at Sony’s expense. For anyone, like myself, who has enjoyed building a collection of ph...

Growing up music-obsessed, my household CD collection was substantial. Along with my own music, it was largely made up of albums my parents had accumulated separately. Like a library filled with books, it unlocked an educational portal on all things music and ignited my respect for the album. And yes, I use the best music streaming services to satisfy my daily music needs, but I’m still an album-listener, and I haven’t left physical music out of my consumption habits. That said, I’ve always imagined what it would be like to bring the nostalgia of CD-browsing into the digital era. Thankfully, Ricardo Amorim is doing just that with his start-up company Spine Music . Launching on Kickstarter this fall, Amorim’s inaugural product is the Spine display, a digital music display you can connect to your Spotify , Apple Music , and Tidal account. But what’s impressive about Spine is that it displays all o...

“It’s not red,” IBM’s design center manager patiently explained. “It’s magenta.” The safety function officer wasn’t buying it. Between his fingers, he held up a small, rubbery disc that looked like a pencil eraser. “You know it’s red and I know it’s red,” he said. The design manager didn’t back down. He insisted that what the man held was indeed magenta. The safety officer called his boss. The boss called Tom Hardy, Design Program Director at IBM. Hardy didn't flinch. “It’s not red. It’s magenta.” It was one of the boldest lies ever told in tech. And it made the ThinkPad iconic. Years later, Hardy relayed the incident in an interview with Laptop Retrospective, detailing the design origins of the TrackPoint, the input stick resting in a central position of the ThinkPad keyboard since 1992. Instantly recogni...

It starts on the 4 Train, that straight-run subway line from Grand Central to Yankee Stadium, where I start to notice the red shirts. By the time I reach the massive gray stadium, people are circling the Bronx Bomber’s edifice like thousands of red ants, all queuing up for a rare baseball season sight: football (soccer) in Yankee Stadium. Most of the shirts are for Premier League side Liverpool FC, but there's a smattering of Wrexham kits. Some of them look threadbare, and none feature the club’s newest sponsor: Firefox. The travel and away kits were unveiled just days before — too soon for die-hard fans to show their support for the team and its well-known but, by some measures, marginal web browser. Walking through Babe Ruth Plaza, I follow behind the red shirts until I’m lined up behind fans who have come from as far as Arkansas and California to witness the pre-season match. None are mus...
