Tempur-Pedic Cooling Tech Helps You Sleep in the Heat

A cool sleep environment doesn't just feel better: Mountains of research show that it's also crucial to getting good-quality sleep. Our bodies begin the transition into sleep by dropping in temperature, and being cool helps us stay asleep so that we awaken feeling ready to tackle the day ahead. But slipping into dreamland can be a difficult task, especially when the summer heat waves set in. Thankfully, Tempur-Pedic's ProBreeze and LuxeBreeze mattresses are specifically built with exclusive coo

I've tested the Apple Watch, Oura Ring, and other sleep trackers - 5 tips to get the best results

Elyse Betters Picaro / ZDNET There are thousands of songs about staying up all night to have fun, yet fewer about how nice it is to go to bed early. After a long day of work, nerve-inducing headlines, and strenuous exercise, all I want is sleep. That's when the lyrics of Hall and Oates' song, "When the Morning Comes," a tune mainly about rejection that can be interpreted as an ode to a good night's rest, come to mind: "It'll be all right when the morning comes," the duo sing. As a sleep enthus

Study finds your smartwatch might be way off on one key health stat

Kris Carlon / Android Authority TL;DR Study finds smartwatch stress scores often don’t match how you actually feel. Researchers tracked 800 Garmin users for three months and saw “basically zero” correlation for stress. Sleep tracking was more accurate, but better at logging hours slept than rest quality. They’re meant to be your health sidekick, you might suspect that there’s only so much that a wearable can tell you about your mental state from taking a pulse reading. If this wasn’t already

TL;DR Samsung’s Galaxy Z Flip 7 and Flip 7 FE now let you add more Android widgets to the cover display. The new foldable phones allow you to add up to four widgets on one screen.

Intel CEO turns Trump around, but his job still hangs in the balance

Last week, President Trump called for the dismissal of Intel CEO Lip-Bu Tan over “highly CONFLICTED” ties to China, further escalating an already difficult situation for the executive. Today, following a meeting, Trump appeared to soften his stance, even if partially. A quick recap Before joining Intel, Tan worked as CEO for Cadence Design Systems, a firm that just pleaded guilty to an investigation by the Justice Department over charges of “selling its chip-design products to a Chinese milit

Get a Free Thing Skin, Thor Skin and More in Marvel Rivals Season 3.5

Looking to Recycle an Old Laptop or Printer? Here's Where You Can Take It

Got an old laptop or printer gathering dust in a closet? You're not alone. A recent CNET survey found that nearly a third of US adults are still hanging onto outdated electronics because they just don't know what to do with them. And while tossing tech in the trash might seem like the easiest option, it's illegal in many states and could land you a fine. The good news? Recycling your old devices is easier than ever. Major retailers like Best Buy, Staples and Office Depot accept laptops, desktop

Google’s unreleased Pixel Tablet Pen had its own magnetic sleeve

TL;DR An X (formerly Twitter) user got their hands on an unreleased Pixel Tablet Pen with the full packaging. It includes a full manual for the device. The stylus would have shipped with a magnetic sleeve that attaches to the back of the tablet. Once upon a time, Google planned to release a stylus for its Android tablet called the Pixel Tablet Pen. However, after the Pixel Tablet 2 was canceled, those plans completely evaporated. Although the Pen never saw the light of day, the unreleased dev

Handsoaps Recalled Over Bacteria That Can Cause Sepsis

The products, DermaKleen, KleenFoam, DermaSarra, and PeriGiene, have been recalled nationwide in the U.S. and Puerto Rico over the bacteria Burkholderia cepacia (spelled as cepecia in the FDA press relea

Engineering Breakthrough Opens Door to Cheap Hydrogen Power

As an alternative to fossil fuel combustion, hydrogen fuel cells hold tremendous promise. But they’re also notoriously difficult and expensive to manage, which largely explains why we don’t see them everywhere (or anywhere, for that matter, except for a few initiatives that are “exploring” their efficiency). But that may soon change. In a Nature Materials paper published August 8, researchers announced the development of a new type of solid-oxide fuel cell (SOFC) that addresses an underlying pr

Google Meet’s new full-screen mode puts presentations front and center

TL;DR Google Meet now has a full-screen option for presentations and screen shares. The feature pushes participants into a sidebar so content takes center stage. It’s rolling out now for Rapid Release and coming August 14 to Scheduled Release. If you’ve spent any time in a Google Meet call, you’ll know that part of the screen is a slide deck and the rest is a gallery of participants reacting or pretending to pay attention. Google’s latest tweak aims to make that first half a little easier to

Optimizing my sleep around Claude usage limits

For the past 4 weeks I have been managing my sleep schedule around maximizing the usage of my Claude Pro subscription. Every five hours your Claude session usage is reset. When I first began using Claude Code daily, this limit would often come at inconvenient times. I would be in flow, vibing with Claude on my B2B SaaS side project. Unfortunately, just as I was stepping into Claude's mind like I'm Raz, the dreaded usage warning would appear. Your limit will reset at 7am. But I was just getting t

How Boom uses software to accelerate hardware development

First in a series on lessons learned at Boom on how to develop hardware quickly and efficiently XB-1 is the world’s first independently-developed supersonic jet, breaking the sound barrier for the first time in January, 2025.

Optimizing My Disk Usage Program

In my previous post, Maybe the Fastest Disk Usage Program on macOS, I wrote about dumac. A very fast alternative to du -sh that uses a macOS-specific syscall getattrlistbulk to be much faster than the next leading disk usage program.

An AI Model for the Brain Is Coming to the ICU

The Cleveland Clinic is partnering with San Francisco–based startup Piramidal to develop a large-scale AI model that will be used to monitor patients’ brain health in intensive care units. Instead of being trained on text, the system is based on electroencephalogram (EEG) data, which is collected via electrodes placed on the scalp and then read out by a computer in a series of wavy lines. EEG records the brain’s electrical activity, and changes in this activity can indicate a problem. In an ICU

Revel shuts down its ride-hail business to focus on EV charging

Revel has shut down its ride-hailing service in New York City, in yet another pivot for the company that started out by renting electric scooters in 2019. Moving forward, Revel will instead focus on its nascent EV charging business, which includes operating five stations in New York and one in San Francisco. A visit to Revel’s app on Monday showed a message thanking users for “riding with us the last 4 years!” and announcing it has “permanently closed our rideshare service.” Revel’s website ech

OpenSSH Post-Quantum Cryptography

5 bloatware apps you should delete from your Samsung phone ASAP

Kerry Wan/ZDNET Samsung phones are well known for One UI, one of the most functional and intuitive Android interfaces. While it's highly customizable, these phones often come with preinstalled bloatware. Some built-in Samsung apps, such as Wearable and Wallet, are useful within the Samsung ecosystem. However, there are at least five first-party apps that even dedicated Samsung users rarely touch. The preinstalled bloatware apps can vary by device, price, and lineup, but many are common across

Self-Guaranteeing Promises

Companies break promises all the time. A self-guaranteeing promise does not require you to trust anyone. You can verify a self-guaranteeing promise yourself. File over app is a self-guaranteeing promise. If files are in your control, in an open format, you can use those files in another app at any time. Not an export. The exact same files. It’s good practice to test this with any self-proclaimed file-over-app app you use. “Stainless steel” is a self-guaranteeing promise. You can test it yourse

Faster substring search with SIMD in Zig

Faster substring search with SIMD in Zig I’ve been learning a lot about low-level programming languages lately, and for a long time there has been one thing that has interested me: SIMD (or ‘single instruction, multiple data’) code. I’ve seen a lot of articles about having massive performance gains by utilizing SIMD and wanted to learn how to do it myself. This article is a journey into implementing ~60% faster substring searching compared to Zig’s std.mem.indexOf using a SIMD-friendly algorit

Best Running Shoes for Women in 2025

Picking out a running shoe is a different experience than shopping for other types of footwear. For one, everyone has different preferences as far as style goes and their running needs. Some shoe brands are known to make shoes for specific types of running (trail, speed, daily), and you may notice some will market themselves as minimalist, maximalist or in-between sneakers. Running shoes, like walking shoes, can also be versatile enough to use for different activities. The only difference is tha

What Does Palantir Actually Do?

Palantir is arguably one of the most notorious corporations in contemporary America. Cofounded by libertarian tech billionaire Peter Thiel, the software firm's work with Immigration and Customs Enforcement, the US Department of Defense, and the Israeli military has sparked numerous protests in multiple countries. Palantir has been so infamous for so long that, for some people, its name has become a cultural shorthand for dystopian surveillance. But a number of former Palantir employees tell WIR
