Hashtags are popular on social media site Twitter for quickly connecting your tweets to global movements, trends, and topics. Now that Facebook supports hashtags are you risking your privacy by using them? Let’s dig in and see what the deal is and whether our curious reader should be worried. When Facebook rolled out hashtags to our account we had the same reaction you did: surely this is a privacy disaster in the making....

We’ve covered two popular file copying programs for Windows: TeraCopy and SuperCopier. But how well do they really work, and do we even need them? We pit them in battle for your amusement, readers, so check out who won. Both TeraCopy and SuperCopier are How-To Geek favorites as alternative file copiers. Both offer extra features, such as queuing files, pausing and resuming transfers, and more. Perhaps most importantly, both make the claim of boosting copying speed....

In C#, the “T” parameter is often used to define functions that take any kind of type. They’re used to write generic classes and methods that can work with any kind of data, while still maintaining strict type safety. We’ll discuss how they work, and how to use them. How Does Work? The “T” variable you’ve probably seen in some method definitions is called a Generic type parameter, or simply just a “Generic....

Geeks often consider encryption a fool-proof tool to ensure that data stays secret. But, whether you encrypt your computer’s hard drive or your smartphone’s storage, you may be surprised to know the encryption can be bypassed at cold temperatures. It’s unlikely that your personal encryption will be bypassed in this way, but this vulnerability could be used for corporate espionage, or by governments to access a suspects’ data if the suspect refuses to disclose the encryption key....

If you’ve jumped on the Google Wifi train (or at least been considering it), then you know there are a lot of reasons to love Google’s mesh network setup. And as helpful as the indicator lights are to let you know everything is powered up and running smoothly, they can also be a distraction. Here’s how to turn them off.

Android Wear is a useful tool to have—notifications on your wrist are a brilliant thing. But it can also be incredibly distracting, especially if the notification isn’t “important.” Maybe you want something on your phone, but it has no place on your wrist. Here’s how to stop specific apps from pushing notifications to your watch. RELATED: How to Set Up, Tweak, and Use Your Android Wear Watch First things first, jump into the Android Wear app....

On Facebook, the News Feed is king. The algorithms behind it control which posts you see from your friends and your frenemies. Every little action you do on Facebook is tracked and it’s all factored in to determine which posts show up first. RELATED: How Facebook’s News Feed Sorting Algorithm Works Sometimes though, Facebook gets it wrong. Your News Feed ends up clogged with articles you’re just not that interested in and posts from people you don’t really know....

RELATED: How to Use System Restore in Windows 10, 11, 7, and 8 You can read more about how to use System Restore in our full guide. But if you’re just looking to create a quick Restore Point, the instructions below should help you out. It is recommended that you create a restore point before installing new software or making any major changes to your computer. Oftentimes, when you install new software, you’re given the choice to create a point but if not you can do one manually as well....

Can hackers really record your webcam during “private” moments, then blackmail you with the footage? This idea, from the latest season of Black Mirror, is downright nightmare inducing. It’s no wonder Mark Zuckerberg and FBI director James Comey both put tape over their webcams. We’ve taught you how to disable your webcam, but what if you still occasionally want to use it? A free Mac application, called Oversight, lets you know when your webcam and microphone are being used, so you can block unauthorized applications from doing so....

I would also suggest that if you are trying to configure a dual-boot system, your best bet is to backup all your data, and setup a fresh new dual boot system, remembering to install the oldest OS first. (XP before Vista, and Linux last) Problem Explanation The main problem that we encounter with the shrink volume feature is that you can’t shrink the volume even when there is clearly free space....

Raise to Wake is a new feature in iOS 10. When you pick your iPhone up, the screen is supposed to turn on so you can see all the revamped notifications on the lock screen. It sounds great on paper, but in reality, it can be a bit finicky to use. Sometimes, when you pick up your phone, you’re left staring expectantly at a blank screen. Rather than write Raise to Wake off, I decided to spend an embarrassing amount of time working out how to reliably trigger it....

Xposed is one of the most powerful tools a rooted Android user has in their arsenal. It brings things to the table that were previously only available on custom ROMs—like custom reboot menus, theme modifications, and so much more. Of course, all that customization comes at a cost: since it modifies the system partition, using Xposed essentially breaks Android’s update system. But not anymore. RELATED: Forget Flashing ROMs: Use the Xposed Framework to Tweak Your Android...

There may be times when you want users of a computer not to be able to change the screen saver. Here’s how to prevent it from happening. Maybe you have PCs in a small business setting and you’d like to make sure employees don’t set inappropriate images or text for the screen saver. Maybe you have a customer-accessible kiosk PC on which you’d rather settings be left alone. Or maybe you just prefer to be in control of what screen saver displays on the family PC....

If you use remote desktop, remote file access, or other server software, you may leave your computer on at home or work when you leave the house. This uses more power. Instead, you could remotely power on your PC whenever you need to use it. This takes advantage of Wake-on-LAN. In spite of its name, it’s possible to set up Wake-on-LAN so that you can send “magic packets” that will wake a computer up over the Internet....

Facebook Messenger on iOS has its own set of emoji, different from the emoji you’re used to seeing in standard iOS apps, such as Messages. If you don’t like the look of the Messenger emoji, you can switch to iOS’ default emoji instead. To switch to the system emoji in Messenger (shown on the right above), you need to change a setting in the Messenger app, not the iOS system settings....

Twitter launched in March 2006, which is crazy: that’s over a decade ago! Even weirder: all the old tweets from that pre-historic era are still out there. Which begs the question: can you dig up really old things that your friends said back in the day? Or perhaps, things your boss said? Halo 2 came out in 2004, so even in 2009 this reference was pretty dated. And how does one beat Tetris?...

You might think your home network is pretty simple, and there’s nothing to be learned from having a deeper look at it. You might be right, but the chances are you’ll learn something you didn’t know. With the proliferation of Internet of Things devices, mobile devices such as phones and tablets, and the smart home revolution—in addition to “normal” network devices such as broadband routers, laptops, and desktop computers—it might be an eye-opener....
