How To: Passcode Lock Your Photos & Messages Apps in iOS 8
I hate to break it to you, but you're probably here because you were trolled. Thanks to a Photoshopped image making rounds across Twitter, Apple fans were tricked into believing that iOS 8 allowed them to lock individual apps, accessible only through a passcode or fingerprint ID. While that's not technically true, we've got the solution for you.
iOS Basics: How to Add Widgets to Your iPhone's Lock Screen & Notification Center
Apple definitely wasn't first to the widget game, but any iPhone running iOS 8 or higher can add widgets to their Today View found via a swipe down from the top of the screen when on the home screen or in any app. There's even access to widgets on the lock screen via the same swipe down on iOS 8 and iOS 9 (on iOS 10, iOS 11, and iOS 12, all you have to do is swipe right on the lock screen).
How To: Theme the Fingerprint Scanner on Your Galaxy S5
The Galaxy S5's fingerprint scanner feels like something straight out of a sci-fi movie. Giving you the ability to lock your device without having to fuss with a PIN or password every time you go to use it, the feature is definitely one of the device's main selling points, especially now that you can use it to unlock individual apps.
How To: App Ops Is Alive! Add It to Your Nexus 5's Settings Menu for Per-App Permissions Control
Android's permissions system is simple, transparent, and straightforward. When installing an app, you get a chance to review all of the permissions that the app has requested. These can range from accessing your location data to holding a "wakelock" in order to prevent your phone from entering sleep mode. But your only choice in this matter is to accept all requested permissions, or not install the app.
How To: Fit More Content on Your Screen by Changing the Pixel Density on Your Android Device
Because of Android's massive array of supported smartphones that carry vastly different display sizes and resolutions, the operating system uses a value known as DPI to determine the size of icons and visual assets that will best suit a given screen.
How To: Why Kitchen Shears Are the Best Tool You Aren't Using
Listen, I'm not disparaging using really good knives—they can literally change your life, or at the very least, the way you work in the kitchen. However, there are many cutting and slicing tasks where you're better off using a sturdy pair of kitchen shears rather than a chef's or even a paring knife.

How To: Secure Android Apps with Mathematical Expressions on Your Galaxy S4
Security is a priority for many when they first set up their mobile devices. Nobody wants to have a stranger or nosey friend go through their phone and discover risqué photos or embarrassing text messages. These days, the closet is gone—everyone keeps their skeletons in their phones.
How To: Cheering Sad Friends Up Might Not Be the Best Way to Help
Contrary to popular belief, taking someone's mind off their sadness and telling them to "cheer up" doesn't do much good. Misery loves company, and while it may be a tiresome cliché, there's actually some science behind it.
How To: Search Gmail & Compose New Emails Straight from Chrome's Address Bar
I'm all about saving time. If there's a quicker way to do something, I'm going to find it. For this reason, whenever I need to search through old emails or compose new ones in Gmail, I do it directly from Chrome's address bar, or as Google likes to call it, the omnibox—and you can, too.
How To: Take Spy Photos & Videos with Your Galaxy S3 or Other Android Phone
There are spontaneous times in everyday life that just scream to be recorded on video. The crazy guy yelling obscenities on the bus. Your favorite actor at the supermarket check-out register. Maybe even your kids just being super adorable.
How To: Have a Drink or Two at Work to Boost Your Creativity & Be More Productive
Boozing it up at work might have been okay back in the days of Mad Men, but today, employers prefer that their workers stay sober.

How To: Access Someone's Thoughts Using Only Their Eye Movements
Look away from this screen and try to remember the sound of your childhood hero's voice. Did you do it? Do it again, and this time pay attention to your eyes.
How To: Rename Almost Any App on Your Samsung Galaxy Note 2
Changing an app's name on your home screen is not something you can do on stock Android or TouchWiz, but it should be. If you think of it merely from a customization angle, sure, it's not a big deal, but having the ability to alter an app shortcut's name can do wonders for cleanliness and being able to distinguish from similar icons.
How To: Install the Samsung Galaxy S5's New Ringtones on Your Galaxy S3 or Other Android Device

How To: The Secret to Washing Your "Dry Clean" Clothes—Without Going to the Dry Cleaner
Unless your work clothes require dry cleaning, you probably only go to the cleaner a few times a year. And for those few items in your closet for which you do, you have to then find the time and extra budget to make a trip all the way to the cleaners and back again. In the end, it can be quite the hassle.
Hack Like a Pro: How to Hack Remote Desktop Protocol (RDP) to Snatch the Sysadmin Password
Welcome back, my budding hackers! One of the keys to becoming a professional and successful hacker is to think creatively.

How To: Give Your Friends Custom Voicemail Greetings & Unwanted Callers the Slip on Your Nexus 5
For my money, one of the greatest improvements brought about from the smartphone revolution is the advent of visual voicemail. No longer do we have to slog through dial menus or trudge through every single message to get to the next. We can just look at our messages, right there on our screens, organized neatly like emails or text messages.

How To: Is Tor Broken? How the NSA Is Working to De-Anonymize You When Browsing the Deep Web
Ever since the FBI took down the Silk Road and Dread Pirate Roberts last month, many questions have been raised about whether Tor still provides anonymity or not, and if it's now broken. I'll try to address that question here today succinctly from multiple angles, keeping it as simple and plain-language as possible. The Closing of Silk Road
Hack Like a Pro: How to Spear Phish with the Social Engineering Toolkit (SET) in BackTrack
Welcome back, my rookie hackers! Many newbie hackers focus upon the technical aspects of hacking and fail to give enough attention to social engineering. In fact, I would say that technical hacks should ONLY be attempted if social engineering attacks fail. Why bother spending hours or days trying to hack a password if someone will simply give it to you?

How To: Change the Text Color & Default Blue Facebook Theme for a More Swaggy Profile
My favorite color is blue, but if everyone I knew said the same thing, I'd probably switch to red—there's nothing cool about uniformity. One place I'm guaranteed to see plenty of my favorite hue is on Facebook. The social network has gone through many redesigns, but its signature color scheme has never changed. While Facebook introduced cover photos, which allows for a little more creativity on your Facebook page, everything else is pretty much the same across all one billion plus profiles. B...
How To: Get Out of Your AT&T Contract Early Without an Early Termination Fee (ETF)
Earlier this month, AT&T quietly introduced a new "Mobility Administrative Fee" which levies a $0.61 monthly charge to all postpaid contracts. While it's a seemingly small amount on an individual basis adding up to $7.32 per year, with its huge customer base, AT&T stands to make around half a billion from the tight-lipped move. AT&T has stated that the fee will "help cover certain expenses, such as interconnection and cell site rents and maintenance" that's consistent with other phone carrier...
Hack Like a Pro: How to Conduct Active Reconnaissance and DOS Attacks with Nmap
Welcome back, my nascent Hackers! In my last blog, we looked at a passive way to gather information necessary for a hack. The advantage of using passive recon is that it's totally undetectable, meaning that the target never knows you're scouting them and you leave no tracks. The disadvantage, of course, is that it's limited to only some websites and not entirely reliable.
How To: Eradicate Unwanted Junk Mail from the Post Office Forever (Or… Repurpose It!)
Unwanted advertising is everywhere. Annoying pop-up ads, overly loud late night commercials, spam...it never ends. And before spam, there was junk mail. Junk mail is even worse because unlike TV commercials and internet ads, it's physical. You can't just delete or ignore it—and it's an awful waste of paper. So what can you do about it?
How To: Tired of Paying for Calls & Texts? These 6 Free Apps Can Cut Down Your Cell Phone Bill
Smartphones are great. They help you keep in touch with your loved ones and stay up to date on what's going on in the world. The problem is that like everything else that's useful, they cost money to use, and between calling, texting, and data plans, it can get really expensive.

How To: 6 Ways to Access Members-Only Websites and Forums Without Giving Up Your Real Info
One of the most frustrating things on the Internet are sites that make you register just to view content. I'm not talking about paywalls—I mean the sites that make you give them personal information to look at free articles or forum threads. Most people are uncomfortable with this because a lot of these sites either spam you themselves, or sell your information to someone else who will.
How To: Hack Someone's Cell Phone to Steal Their Pictures
Do you ever wonder how all these celebrities continue to have their private photos spread all over the internet? While celebrities' phones and computers are forever vulnerable to attacks, the common folk must also be wary.

How To: Don't Like Traditional Christmas Trees? Try Out One of These 7 Festive DIY Alternatives
The concept and structure of Christmas hasn't changed much since its inception. In its infancy, Christians recruited Roman pagans by associating Christmas with the Saturnalia, an ancient Roman festival in honor of the deity Saturn (also held in December). The pagans had long worshiped trees (as did other historical cultures) and would bring them into their homes and decorate them, something that influenced our modern holiday decorations. While certain things such as gifts and ornaments have b...
