Signal secures all your conversations with end-to-end encryption, offering more privacy and security than your average chat app. But Signal offers some other useful security options. Here’s how to take advantage of them. Enable Registration Lock to Protect Your Signal Account Your Signal account is tied to your phone number, with no need for a password at all. When you first register for Signal (or re-register a device at a later stage), Signal will verify who you are by sending a code to your number. Enter the code to prove you are who you say you are and you’re good to go. But what happens if someone gets access to your phone number? While this might seem like an unlikely eventuality, it’s within the realm of possibility. Someone could steal your smartphone’s SIM card or fool your phone service provider into transferring your number to a new SIM using social engineering techniques . With access to your phone number, someone could gain access to your entire Signal … [Read more...] about How to Make Your Signal Chats as Secure as Possible

The HomePod mini uses the proximity-sensing U1 chip that makes certain models of iPhone vibrate when they get near. This allows you to “hand off” music to the speaker, but some people don’t find the feature particularly useful. If the vibrations and notifications are driving you mad, you can turn the feature off. How to Turn off Proximity Features You’ve probably noticed this feature if you have a HomePod mini and a recent iPhone like the iPhone 12, 12 Pro, 11, and 11 Pro. These devices can take advantage of the U1 chip in the HomePod mini, automatically sensing when the smart speaker is within range. When you get close to a HomePod mini, certain iPhone models will start to vibrate. These vibrations will increase in intensity the closer you get, and the screen will blur and give you audio controls instead. Any music you are playing will be transferred to the speaker. To turn the feature off, first, launch the Settings app and tap “General.” Scroll down and … [Read more...] about How to Turn off HomePod mini Proximity Vibrations and Notifications on iPhone
The power supply (PSU) is a critical part of any PC. It powers all the components in your PC, and a bad or faulty one can bring everything down. Here’s what to look for in a power supply while putting together a PC. A PSU Is a Critical Piece of PC Infrastructure When we turn on a light, open a faucet, or walk down a nicely paved street, we don’t often think about the wondrous infrastructure making all that possible. But if somebody hadn’t taken the time to think about it, things wouldn’t be so wondrous. It’s the same when building a PC. We get obsessed with how many cores a CPU has or the number of compute units in a GPU . But rarely do we think twice about the power supply unit (PSU,) which provides power to everything else in your PC. You don’t need to think about your power supply too much, of course. But, if you don’t consider the PSU at all, there’s a good chance you’ll be thinking about it a lot once it starts causing problems. If your computer doesn’t get … [Read more...] about How Important Is the Power Supply (PSU) When Building a PC?
High-quality sound on PCs from drop-in sound cards and external DACs is a weird subject. It’s not as necessary as it once was. In fact, nobody even thinks about it much anymore. There’s no song or game that you won’t be able to listen to because of underpowered gear. Sound vs. Graphics Hardware Your computer’s built-in sound is pretty good for most tasks. Contrast that with gaming, where if you want to play the newest AAA games at high frame rates, you need a graphics card. A CPU’s integrated graphics processor simply isn’t up to the challenge. Nevertheless, some people still want better sound than a motherboard can offer. When that’s the case, it comes down to two primary choices: a sound card or an external DAC (digital-to-analog converter). A quality listening experience needs a minimum of electrical interference, which is a problem because a PC motherboard is a hotbed of electrical activity. That’s why onboard motherboard audio has shielding to protect itself as best … [Read more...] about What Is an External DAC, and Do You Need One for a PC?
If you’re a photographer, you know that capturing RAW photos allow you to edit them after the fact without sacrificing quality. With Apple ProRAW available on iPhone, you can replicate that experience while continuing to use the company’s other photography smart features. What is Apple ProRAW? Smartphones like the iPhone use computational photography to improve the look of the photos they take. Apple’s built-in Smart HDR, Deep Fusion, and Night Mode features use machine learning to take higher resolution and crisper shots even in poor lighting situations. Unfortunately, it’s not possible to capture a true RAW photo and still use Apple’s smart technology. You can take RAWs with an iPhone , but it won’t use any machine learning to improve the image before it’s captured. But with ProRAW, you get something between a standard iPhone HEIC or JPG and a RAW file that holds a record of what the sensor captured. ProRAW is Apple’s custom, in-house RAW format. When capturing … [Read more...] about How to Shoot Photos in ProRAW on an iPhone
