The 12 Most Effective Cardio Workouts

Cardio is more than just running laps or hopping on a bike. It's any movement that gets your heart pumping, your body sweating and your energy levels soaring. Whether you're chasing a weight loss goal or looking to boost endurance, there's a cardio workout that fits your mood and motivation. Not into high-impact moves? Go for swimming or a rowing session that's easier on the joints. Want something that pushes your limits? Sprinting or HIIT might be your jam. Cardio is flexible and lets you mix i

Inside the US Government's Unpublished Report on AI Safety

At a computer security conference in Arlington, Virginia, last October, a few dozen AI researchers took part in a first-of-its-kind exercise in “red teaming,” or stress-testing a cutting-edge language model and other artificial intelligence systems. Over the course of two days, the teams identified 139 novel ways to get the systems to misbehave including by generating misinformation or leaking personal data. More importantly, they showed shortcomings in a new US government standard designed to h

First impressions of Alexa+, Amazon’s upgraded, AI-powered digital assistant

I owned a lot of Alexa-powered devices in my former home: There were Amazon Echos in most rooms, including an older Echo Plus in the living room, a smattering of Dots, a Spot in a bedroom, and an Echo Show in the kitchen. A Fire TV ran in the bedroom. And, in a drawer, a rarely used Fire HD tablet sat collecting dust. With the total loss of the home due to a March 2024 house fire, there also came a new opportunity: We could now make a fresh start to create a more modernized smart home after reb

Instagram is two months shy of turning 15, and as a sign of maturity, we’re getting the first official repost button: With reposts, you can repost public reels and feed posts, making it easie

LLM Inflation

One of the signal achievements of computing is data compression : we take in data, make it smaller while retaining all information (“lossless” compression), transmit it, and then decompress it back to the original at the other end. For many years, compression was an absolute requirement to get things done: storage devices were too small for the data we wanted to store and networks too slow to transmit what we wanted at an acceptable speed. Today compression is less often an absolute requiremen

Nigerian national Chukwuemeka Victor Amachukwu has been extradited from France to the U.S. to face charges of hacking, fraud, and identity theft for suspected spearphishing attacks on U.S. tax preparation businesses. The attack were designed to steal personal data and file fraudulent tax and loan applications, allowing threat actors to steal over $3 million in total. Specifically, the Nigerian national allegedly obtained approximately $2,500,000 from fraudulent tax refunds (out of $8.4 million

A New ‘Foundation’ Clip Digs Into Some Prickly Family Dynamics

When Foundation fans first met newlyweds Toran (Cody Fern) and Bayta (Synnøve Karlsen) Mallow, two things stood out: first, that last name, signifying Toran’s connection to season two hero Hober Mallow; second, the way their self-aware glamour made them very much resemble futuristic versions of the social media influencers we have today. But it was also apparent there was substance beneath the sparkle—and episode five, “Where Tyrants Spend Eternity,” explores that idea even more. io9 has an exc

Five ways that AI is learning to improve itself

That’s why Mirhoseini has been using AI to optimize AI chips. Back in 2021, she and her collaborators at Google built a non-LLM AI system that could decide where to place various components on a computer chip to optimize efficiency. Although some other researchers failed to replicate the study’s results, Mirhoseini says that Nature investigated the paper and upheld the work’s validity—and she notes that Google has used the system’s designs for multiple generations of its custom AI chips.

How to check for bad blocks on a Linux PC hard drive (and why you shouldn't wait to do it)

Kyle Kucharski/ZDNET I've had it happen before. Back when drives consisted of spinning, magnetic platters, that dreaded "tick" was a sure sign a hard drive was failing. Once upon a nightmare scenario, I waited too late and wound up losing everything on my drive. Sure, I could have recovered that data, but at a pretty high monetary cost. Also: The first 5 Linux commands every new user should learn Since then, I've always been vigilant about checking for bad blocks and sectors on hard drives.

How to Scale Proteomics

A cell is a vibrating bag of molecules, densely packed with DNA, proteins, RNAs, and lipids. The ratios of these molecules are not balanced, though. A typical HeLa cell, widely used as a model to study cancer in the laboratory, has about 20 times more protein than DNA by mass. Such imbalances are pervasive across the tree of life, but proteins are always the heaviest and most diverse group of molecules within a cell. A single human cell encodes more than 20,000 proteins, each built from 20 stan

Yamaha’s New Soundbar Has More Up-Firing Dolby Atmos Speakers Than There Are ‘Fast and Furious’ Movies

Sometimes more is better. Case in point: money. I could really use more money, and if you gave me more money, I’d be happy about that—I think most would agree with that sentiment, and if you don’t, I have a favor to ask. Speakers, like money, are also a thing you may want more of, and while they’re not as important as money, they’re important for your ears, and Yamaha is here to take your money in exchange for satisfying your ears in a very maximalist way.

I switched to the Dell 14 Premium for two weeks, and it made my XPS laptop look bad

Dell 14 Premium ZDNET's key takeaways Dell's latest high-performance laptop is currently on sale starting at $1,500.

5 command line backup tools every Linux user should use for desktops and servers

Javier Zayas Photography/Getty Images I use Linux for both desktop and server. My preference for a server OS is one without a GUI, which means I have to turn to a lot of command-line tools. In some cases, I prefer to use the same command-line tools for both desktop and server, because it simplifies everything. After all, I don't want to have to learn two different tools for the same job. On top of that, the command-line tools I've included in this list are very powerful and flexible enough to m

Thank God James Gunn Changed His Mind About Giving Superman Red Trunks

By this point, it’s safe to say that Superman has been an enormous success, both at the box office and among audiences and critics, for director James Gunn and the team at DC Studios.

Yesterday, graphic and surface designer Maybelle Pineda shared a post that gives DC fans a behind-the-scenes look at the creation of

Instagram is getting several new features that pull from competitors, and it’s updating a controversial feature that it added earlier this year. Starting today, users will have the ability to repost public Reels and grid posts from other accounts. And similar to TikTok, reposts will be collected in a designated tab on your profile and sprinkled into the feeds of people who follow you.

The Switch OLED went up in price, but you can still save $110

Nintendo recently made the unexpected decision to increase the prices of its last-gen Switch hardware due to “market conditions,” adding $30 to the cost of the $199.99 Switch Lite, $40 to the standard $299.99 Switch, and $50 to the $349.99 Switch OLED. The price difference between the Switch OLED and the standalone Switch 2 now stands at a mere $50.
