That’s the idea behind Quicksilver, an open source Mac application that makes launching software and a bunch of other tasks a lot faster. It’s easy to look at Quicksilver as a replacement for Spotlight, and it’s true that both can be used to quickly launch Mac applications. But beyond that, Quicksilver is an application that rewards users for digging in and learning more. With a little bit of configuration you can quickly crunch numbers, add items to your calendar, and search specific websites, all without touching your mouse....

Enable Fall Detection When you first set up your Apple Watch, it should have asked if you’d like to enable fall detection and emergency services. If you didn’t turn the feature on (or want to make sure you did), start by opening the “Watch” app on your iPhone. If you can’t find the app on your iPhone, swipe down on your homescreen and use Apple’s Spotlight search to find “Watch.”...

Bright blue-white light blasting in your face at night isn’t so great for your sleep or general health, but don’t worry; iOS supports color shifting so you can warm up the light of your iPhone for easy nighttime reading. RELATED: Artificial Light Is Wrecking Your Sleep, and It’s Time to Do Something About It There is a growing body of research suggesting that exposure to artificial light late into the evening, especially blue light like the crisp blue-white glow of our beloved gadgets, is a serious issue that affects our sleep cycles and general health....

So everyone knows that their preferred keyboard on Android has autocorrect, but did you know Android also has built-in spell check?

Spell Check vs. Autocorrect RELATED: The Best Keyboard Apps for Android One of the first things you’re probably wondering here is what makes spell check different than autocorrect....

RELATED: How to Reset Network Settings on Android How Factory Resets Work on Your Samsung Android Phone When you reset your phone, your phone deletes all your customized settings, apps, games, and everything else you’ve stored on it. Once the reset is done, you can set up your phone from scratch.

If you ever decide to sell or give your SmartThings hub to someone else, you’ll want to make sure that you reset it to the factory defaults, so the new owner can start from a clean slate. Here’s how to do that. RELATED: How to Set Up the SmartThings Home Monitoring Kit Keep in mind that factory resetting your SmartThings hub will erase everything, including the connections for all your sensors, as well as any automation tasks and routines that you have set up in the app....

Each network card on your computer has a built-in unique MAC (Media Access Control) address that can be used to identify your computer. This is usually fine, but it is possible to change it natively in OS X. RELATED: What Exactly Is a MAC Address Used For? If you are running Windows or Linux you can change your MAC address easily on those platforms as well, though we should note that this is more of an advanced topic and most people shouldn’t change their MAC addresses unless they really need to....

Google released an Android version of Chrome in 2012, and have never bothered to give it a fullscreen mode. If you’re tired of waiting on your favorite Android app to offer fullscreen, there’s a way to do it yourself with Immersive Mode. Come on Google, I’ve literally been begging you for years! There’s just no reason not to give us a fullscreen mode. There are ways to do this with third-party apps like Tasker, but assuming you’ll always want to keep a specific app in fullscreen, there’s a faster and more practical way to do it using only the Android debug bridge (ADB) desktop tool....

No one enjoys manually entering tons of data from printed material into a Microsoft Excel spreadsheet. You can save time, reduce the risk of errors, and eliminate a tedious task with the Data From Picture feature. Excel’s Data From Picture feature scans an image (for example, a table of values printed in a magazine, a printout of financial transactions, or even a screenshot of a table from a website) and analyzes it to find the relevant data....

There are tons of third-party partition managers for Windows, but did you know that Windows includes its own? Microsoft did a good job of hiding the Disk Management tool, but it’s there. RELATED: Beginner Geek: Hard Disk Partitions Explained You can use the Disk Management tool to resize, create, delete and format partitions and volumes, as well as change their drive letters—all without downloading or paying for any other software....

One point we often return to at How-To Geek is that to take better pictures, you need to understand how to manually control your camera—even if you don’t do it for every setting or shot. Your iPhone is no exception. Unfortunately, iOS doesn’t offer manual controls in the default Camera app so we’ll need to go with a third-party app. Apple (chasing Google) has continued to innovate and add software features to the Camera app—things like Smart HDR and Portrait Mode....

The Linux File System The file systems in Linux, macOS, and other Unix-like operating systems don’t use separate volume identifiers for storage devices in the way that, say, Windows does. Windows assigns each volume a drive letter such as C: or D: and the file system for each volume is a tree of directories sitting below that drive letter. In Linux, the file system is an all-in-one directory tree. A mounted storage device has its file system grafted onto that tree so that it appears to be an integral part of one cohesive file system....

Some games never go out of style. Over two decades after its release, Doom still enthralls players with its fluid, first-person shooter action. Thanks to a range of modern ports, you can now play the game with enhanced graphics and controls.

Its enthralling atmosphere, violence, dark themes, and innovative network support made it popular....

The good news is, with a simple $5 app, you can turn your Apple TV into a very capable video streaming device that will play virtually any TV shows or movies you have stored on your PC or Mac....

Chrome has built-in memory management that causes inactive tabs to “sleep” as RAM is filled. When you click the tab again, it has to reload the page. It’s annoying. While memory management is important, constant reloads can be exceedingly irritating—especially if you work with a lot of Chrome tabs at once. The more tabs you have open, the more likely they are to be moved out of memory and into this “sleep” mode as RAM starts to get full....

HomeGroups in Windows are great for sharing files between computers on a local network. At some point, though, you might find it necessary to disconnect from a HomeGroup. Here’s how to do it. HomeGroups make sharing files and printers between PCs on the same local network really simple. But you might find yourself needing to disconnect from a HomeGroup for whatever reason. Maybe you don’t need to share files anymore, or maybe you’re just setting things up from scratch again....

Apple’s HomeKit home control and automation system is largely plug, play, and enjoy, but sometimes stubborn devices need a nudge to play nice. Read on as we show you how to reset both devices and the general HomeKit configuration. In most cases, setting up your HomeKit equipment is pretty easy stuff. But if the company’s companion app crashes, if the HomeKit device gets added to the wrong device in your household, or there is some electronic gremlin you can’t quite pin down, then it’s time to tinker with your HomeKit configuration....

Let’s be honest here: GIFs and emoji are the new form of communication. As silly as they may seem, they somehow add an additional layer to the way we interact with friends and family over text or instant messages, which can otherwise come off as dry. While emoji has long been a part of Google Keyboard, Google added a way to search them—as well as GIF integration—into the new Gboard update....

Back in May of 2016, Dropbox announced on its official blog that it now has half a billion users. That’s a lot of people, which also means there’s likely a lot of information being stored in this cloud service that you wouldn’t want other people seeing. If you’re one of those 500 million, it’s time to secure your account. Choose a Strong Password Wait, don’t skip this section! I know you’ve heard this a million times, but there’s a reason: it’s important....
