This next-gen flagship has a rear screen that’s basically the Z Flip 7’s cover display

TL;DR A Xiaomi 17 Pro series teaser video shows off several uses for the rear display. The rear screen can show various clock styles, lock screen text, avatars, and more, much like a Flip phone’s cover display. A previous leak also notes that this screen can display exercise info, app notifications, and ‘travel card’ swiping. The Xiaomi 17 series will be the first phones with the Snapdragon 8 Elite Gen 5 processor. Xiaomi confirmed that the Pro phones have a rear screen, and a new teaser has

Should we drain the Everglades?

Lake Okeechobee, the largest lake in Florida, has an average depth of only nine feet (2.7 meters). Oh, and it has 30,000 alligators, but try not to think about that. Dough4872 , CC BY-SA 4.0 , via Wikimedia Commons I can’t explain why this bothers me so much, but something about it being so big and yet so shallow just creeps me out. I find it unsettling, okay? Mentally, it makes me feel like noodles, if that makes sense. It’s the eighth-largest (freshwater) lake in the country but I’ve swam i

Don’t worry, the Apple MacBook Air M4 is back to its record-low price!

Slow Social Media

Slow social media 16 Sep, 2025 People often assume that I hate social media. And they'd be forgiven for believing that, since I am overtly critical of current social media platforms and the effects they have on individuals and society; and deleted all of my social media accounts back in 2019. However, the underlying concept of social media is something I resonate with: Stay connected with the people you care about. It's just that the current form of social media is bastardised, and not socia

LimeWire (Which Still Exists) Buys Fyre Festival (Which Never Did) on eBay

Mix two internet touchstones together and what do you get? We’re going to find out. LimeWire, the peer-to-peer file-sharing network, announced that it won the rights to the Fyre Festival brand in an auction. The company indicated it has no plans to use the branding for a music festival, but rather bought up the name and likeness mostly for the memes. LimeWire said in a press release that it plans to “unveil a reimagined vision for Fyre — one that expands beyond the digital realm and taps into r

Meta Connect 2025: What to expect and how to watch

Meta Connect 2025 — the company’s biggest conference of the year where it unveils smart glasses and VR headsets — kicks off on Wednesday night. We’re expecting the star of Meta Connect 2025 to be the company’s new AI-powered smart glasses with Ray-Ban and Oakley, but the company may have some other surprises in store regarding the Metaverse, Quest headsets, or even its broader AI ambitions. Meta says it has sold millions of Ray-Ban Meta smart glasses, and earlier this year, Meta unveiled its la

NHTSA is investigating Tesla over its electronic door handles

Who says journalism is dead? Less than a week after Bloomberg published a damning report about Tesla's "dangerous doors," the US National Highway Traffic Safety Administration (NHTSA) is now looking into it. On Tuesday, the regulator said it opened an investigation into the automaker's electrically powered doors. The problem: They stop working if the vehicle's low-voltage battery fails. The NHTSA's probe will cover the 2021 Model Y, which covers an estimated 174,290 vehicles. But the agency sug

Implicit ODE solvers are not universally more robust than explicit ODE solvers

A very common adage in ODE solvers is that if you run into trouble with an explicit method, usually some explicit Runge-Kutta method like RK4, then you should try an implicit method. Implicit methods, because they are doing more work, solving an implicit system via a Newton method having “better” stability, should be the thing you go to on the “hard” problems. This is at least what I heard at first, and then I learned about edge cases. Specifically, you hear people say “but for hyperbolic PDEs

Wind turbine blade transportation challenges

The world’s largest airplane, when it’s built, will stretch more than a football field from tip to tail. Sixty percent longer than the biggest existing aircraft, with 12 times as much cargo space as a 747, the behemoth will look like an oil tanker that’s sprouted wings—aeronautical engineering at a preposterous scale. Called WindRunner, and expected by 2030, it’ll haul just one thing: massive wind-turbine blades. In most parts of the world, onshore wind-turbine blades can be built to a length o

In Defense of C++

Dayvi Schuster 12 min read Tuesday, September 9, 2025 In Defense of C++ Why C++ remains a powerful and relevant programming language in today's tech landscape. The Reputation of C++ C++ has often and frequently been criticized for its complexity, steep learning curve, and most of all for its ability to allow the developers using it to not only shoot themselves in the foot, but to blow off their whole leg in the process. But do these criticisms hold up under scrutiny? Well, in this blog post,

Xiaomi 17 Pro has an iPhone-like design, but with a second display on the back [Video]

Ahead of its formal debut in the near future, Xiaomi is showing off the new Xiaomi 17 Pro, which has an iPhone-like camera bar on the back, but uses that real estate for a rear display. In a post on Weibo, Xiaomi shares a brief video that shows the Xiaomi 17 Pro. At first, the phone is shown with a sectioned design that features a section along the top that includes the cameras. It’s not quite a Pixel-like “Camera Bar,” but rather more similar to Apple’s iPhone 17 Pro redesign. The twist, thou

Scuba-Suit-Clad Thief Steals Thousands of Dollars From Floating Disney World Restaurant in Heist Ripped Right Out of the Movies

When we hear of criminal activity at Walt Disney World, it’s not usually pertaining to an action sequence that feels like it’s come right out of a Disney movie itself. But that was apparently the case this week in Orlando, when over $10,000 was stolen from a Disney World restaurant by a scuba-diving criminal mastermind. WFTV9 (via Cinemablend) reports that in the early hours of today, an unidentified man staged a robbery at the Paddlefish seafood restaurant in Disney Springs, a shopping and din
