From Apple’s iPhone to high-end Android phones from manufacturers like Samsung, every flagship phone has a camera with a night mode now. Here’s how these phones manage to take such detailed shots, even in poor lighting conditions. Night Mode Keeps Getting Better Every year, smartphone manufacturers tout the new and improved cameras on their latest flagships, and with good reason. Over the last few years, phone cameras, and the image-processing techniques that power them, have become exponentially better at capturing photos in challenging lighting. Just a few years ago, phones had trouble capturing even half-decent photos in the dark unless the flash was used. Now, they can capture a spectacular amount of detail, even when shooting subjects that would be challenging for professional-grade mirrorless or DSLR cameras. Apple also improved the low-light camera on its iPhone 12 series . The press shots included several of dimly lit areas in the middle of the night. Using … [Read more...] about How Does “Night Mode” Work on Smartphone Cameras?

FragAttacks are a group of security vulnerabilities that can be used to attack Wi-Fi devices. Every Wi-Fi device ever created appears vulnerable, making it possible for attackers to steal sensitive data or attack devices on your network. Here’s what you need to know. What Are FragAttacks? Disclosed on May 12, 2021, FragAttacks stands for “ fr agmentation and ag gregation attacks .” These are a collection of security vulnerabilities announced together. Three of them are design flaws with Wi-Fi itself and affect most devices that use Wi-Fi. Additionally, the researchers found programming mistakes in many Wi-Fi products. These are even easier for attackers to abuse than the design flaws in Wi-Fi itself. The collection of vulnerabilities called FragAttacks were discovered by Mathy Vanhoef, the same security researcher who previously discovered KRACK , an attack on the WPA2 encryption protocol used to secure Wi-Fi networks. Which Devices Are Vulnerable to … [Read more...] about How to Protect Your Wi-Fi From FragAttacks
AirTags are small, coin-sized Bluetooth trackers that allow you to locate items near and far. This functionality is powered by Apple’s network of hundreds of millions of iPhones, iPads, and Macs already in the wild, providing unprecedented coverage on a global scale. While it might be tempting to put an AirTag on everything , there’s one thing you definitely shouldn’t track—and there are many reasons why that is the case. AirTags Are Designed to Track Objects The one thing that AirTags were not designed to track is people. There are naturally quite a few ethical and legal issues involved with tracking someone against their will, but that’s only half of the story. AirTags are designed to track things that you interact with regularly, whether it’s your bag, your golf clubs, or even your cat. It’s reasonable to expect that your iPhone will “touch base” with these items regularly while you’re at home or work. When an AirTag is away from its owner for three days, it … [Read more...] about The One Thing You Shouldn’t Track with Apple AirTags
Few amenities in the modern digital workflow are so widely available but so widely ignored (or outright abused) as the the email BCC function. If you’re guilty of misusing or neglecting its power (and there’s a good chance you are), it’s time to repent and, in the process, cut down on spam and protect the privacy of your friends and family. What Is BCC and Where Did It Come From? RELATED: What's the Difference Between CC and BCC When Sending an Email? There are three address slots in every email client: TO, CC, and BCC, which stand for “[deliver] to”, “carbon copy”, and “blind carbon copy”, respectively. These denotations are a holdover from the world that preceded electronic mail: physical letters and memos. In mid-century business memos, for example, there would be a TO slot for the primary recipient, a CC slot for individuals who needed to be in on the communication but who were not the primary recipients, and a third slot, BCC, for individuals who needed to be … [Read more...] about What BCC Is, and Why You’re a Terrible Person If You Don’t Use It
The Tor Project says that you can’t run the full version of the anonymizing Tor browser on a Chromebook. But, by using your Chromebook’s Linux subsystem, you can install and use it very easily. Here’s how. What Is Tor? The Tor Project has created a free, anonymizing computer network that anyone can use to maintain their privacy online. The Tor network uses the regular internet infrastructure along with its own overlay network of volunteer-provided Tor nodes. These do the routing for the Tor network traffic. They encrypt your traffic and use other tricks to make back-tracing and identifying your IP address difficult to the point of being almost impossible. RELATED What Is a VPN, and Why Would I Need One? The Tor browser allows you to access websites on the Tor network as well as on the regular web, which is known as the clear web. In both cases, your network traffic is routed over the Tor network. But remember that your traffic has to emerge from the cover of … [Read more...] about How to Install the Tor Browser on a Chromebook
