Apple's latest updates are all about AI—Apple Intelligence, that is. When you update to iOS 27 and macOS 27 Golden Gate, Apple will invite you to try Siri AI and other new Apple Intelligence features. (Assuming your iPhone supports Apple's AI features.) But whether you use the new AI-powered Siri all the time or find yourself frequently scrolling past the AI additions, Apple Intelligence is taking up space on your device—perhaps requiring more storage than you bargained for.I'll admit, I didn't think much of it when I updated my iPhone and Mac to the latest versions. I gave Siri AI a shot, adjusted Liquid Glass, and went back to doing pretty much the same things I was doing before I made the update. But once I saw headlines about how much storage Apple Intelligence actually takes up on the...

We may earn a commission from links on this page. When I test smartwatches and fitness trackers, I place a particular emphasis on accuracy. Is my running pace correct? Does the device capture the ups and downs of my heart rate? I even got a VO2max lab test to check a bunch of watches' fitness scores. But one thing I never test for accuracy is calorie burn. None of my devices come close to agreeing on the number of calories they think I'm burning, and I don't expect them to. Even scientists who study the accuracy of wearables can't answer the question in a way that's useful when you're shopping for this year's devices—but we'll get into why that is below. There was a time, before Fitbits, when nobody knew quite how many calories they were burning on a daily basis. Sure...

A VPN conceals your IP address by routing your internet traffic through a remote server, preventing anyone surveilling the network from tracking your online activity. Theoretically, that means no one should be able to identify you when you connect to a network and browse the internet, even your ISP. In practice, though, there are plenty of gaps that hackers can exploit. A while back, Lifehacker covered browser fingerprinting, which uses hundreds of data points, like your hardware specs, operating system version, web browser, and GPU signature, to establish a shadow profile that follows you around even when your VPN is enabled. There's another way cyberattackers can intercept your data, and it involves exploiting a communication leak right inside your browser. Major browsers like Chrome, Fi...
