How To: Snapchat Increases Its Security Push, Adds Image Captcha Feature

Snapchat has had more than its fair share of security failures and mishaps. The photo-sharing company is looking to better address some of these security gaps by adding new features, and today its most recent addition is live: the Captcha. New users will be asked to verify their "humanness" by selecting the infamous Snapchat ghost out of a selection of images. The feature is supposed to help block hacker-made bots from creating fake accounts or accessing existing ones. But rather than using t...

How To: The Fastest Way to Share Large Files from a Nexus 7 to a Samsung Galaxy S3 or Other Android Device

Recently, I wanted to share a large video file from my Nexus 7 to my friend's Samsung Galaxy S3, and even though he was standing right next to me, it was an extremely difficult and frustrating thing to do. Every single Nexus 7 tablet comes NFC equipped, so it can share files with other NFC-equipped devices just by tapping and holding them together. With both NFC and Android Beam enabled, sharing a small file between two devices should be fairly simple.

How To: Fix the Home Button Lag on Your Samsung Galaxy S4

Your new Samsung Galaxy S4 is fast, but it can definitely be faster. One issue that carried over from the Samsung Galaxy S3 is Home button lag. Instead of it being an instantaneous response, it takes a split second for the action to take place—and a split second is enough to irritate the best of us. The culprit here is S Voice. The built-in voice assistant is great, but whether or not you use it, one of its features remains persistent—its strenuous use of the Home button—where you double-tap ...

How To: Put Your Samsung Galaxy Note 2 in Deep Sleep Mode to Save Battery Life

Newer smartphones are more power hungry than ever before, and the Samsung Galaxy Note 2 has a mighty appetite for amps that only Jenny Craig could possibly curb. On average, your Note 2 (or other Android device) lasts for what, a day, maybe two days before dying. Mine barely lasts 8 hours! This is thanks to all of the apps running in the background of your phone, even when you're not using them, eating through all of your CPU, leaving nothing but crumbs.

How To: Who's Unfollowing Your Twitter Account? Find Out with These Tracker Apps (And Get Revenge!)

Feelings can get hurt on Twitter as fast as an update. Everything is fine and dandy because two people are mutually following each other, then out of nowhere, one person has unfollowed the other out for seemingly no reason.

Well, now you can find out who unfollows you on Twitter with these mobile apps.

How To: Save Some Cash on Apple's New Hybrid Fusion Drive and Make Your Own!

At the most recent Apple event, the company announced its new Fusion Drive, a hybrid hard drive designed to increase performance and speed by combining traditional and flash storage. It's composed of a small solid-state disk and a larger spinning hard disk drive, and files and applications are moved back and forth between the two based on how often you use them. A chunk of memory is reserved for whatever task you're currently doing, which means that multitasking doesn't slow down your compute...

How To: Make Water Droplets "Levitate" on Water (Using Vibrations)

You can take some really awesome photos of water droplets if you've got a fast enough camera (and flash), but water drops aren't just spectacular as photographic subjects—you can also make them a part of the photographic process by using a water drop as a DIY projection microscope and even a macro lens for your iPhone. But as useful as a water drop can be, it's still way cooler when they're in front of the camera (as the subject). Recently, researchers from the National Autonomous University ...

News: Post-TIFF Micro-Blurbs

Every year the fine folks at Row Three do a post-TIFF mega-wrap up, collecting the micro-blurbs of a bunch of attendees into a giant meta-analysis of what everyone liked, loved, hated, etc. etc.. We'll link to that post when it goes up on the weekend, but in the mean time, here's my contribution:

News: This Real-Life Star Wars Hover Bike Could Be the Future of Personal Transportation

Admit it—at some point or another, you've wished that you had your own personal hovercraft. Don't worry, we've all been there. Well, a company called Aerofex wants to make a hovercraft that's way more than your standard leaf-blower-powered one, taking a queue from the swoop and speeder bikes from the Star Wars franchise, building their own sort of repulsorlift. This hover bike may not be quite as fast as the ones from Star Wars, but if the company has its way, it could be on sale by the end o...
