Hacking Pranks: How to Flip Photos, Change Images & Inject Messages into Friends' Browsers on Your Wi-Fi Network

Networking is built largely on trust. Most devices do not verify that another device is what it identifies itself to be, so long as it functions as expected. In the case of a man-in-the-middle attack, we can abuse this trust by impersonating a wireless access point, allowing us to intercept and modify network data. This can be dangerous for private data, but also be fun for pranking your friends.

How To: Recreate Snake Eater's Costume from Metal Gear Solid 3: Snake Eater

If you're a fan of the Metal Gear video game series, an obvious Halloween costume choice would be Solid Snake, the protagonist of nearly all of the games.

He's was once a good man, but better known as the nemesis to Solid Snake. The below costume by YouTube user Erick Zeros showcases Naked Snake in his good era, in Metal Gear Solid 3: Snake Eate...

How To: Build a Low-Cost Shoe Rack Using PVC Pipes

How To: Discover the Hidden Colors in Everyday Objects with This DIY Video Spectrometer

A spectrometer is a device that splits light into all of the different colors it's composed of that can't be seen with the naked eye. It does this by using a prism to refract or bend the light. Jeffrey Warren over at Public Labs created a tutorial showing how you can make your own video spectrometer and create spectra like the one pictured below. Any guesses as to what the subject is? Believe it or not, that's what whipped cream looks like when viewed through a spectrometer. You can do this w...

How To: Use Quote Replies in Facebook Messenger to Prevent Confusing Conversations, Just Like in WhatsApp

Text conversations can get confusing fast. In the time it takes to type up a response to your friend, they can send you one, two, three, or more messages. Once you send the original reply, it no longer makes sense in the context of the chat. Clear up the confusion with Facebook Messenger's "new" quote reply feature, which shows both you and your friend exactly what message you're responding to.

Imagine what your child could do if they were able to harness this technical aptitude and put it to good use — and they can, with learning apps.

How To: Disable the Always-on Ambient Display on Your Pixel 2 or Pixel 2 XL

Unlike traditional backlit LCD technology, OLED screens don't use any power to display black pixels. Many manufacturers have taken advantage of this by implementing an always-on display, which only lights up a few pixels here and there to show relevant info when your phone is locked. But this leads to extra battery drain, albeit small, and it increases the risk of screen burn-in.

How To: Use the Much-Improved Face Unlock Feature in Android Lollipop

I think it's safe to assume that most of us appreciate a little privacy and security when it comes to our mobile devices, which is exactly why we have lock screens that require unique passwords, patterns, or PINs. Although someone can discretely peer over your shoulder to see what your password is, it's much more difficult for them to duplicate your face to unlock the device.

How To: "Find & Replace" Text Directly in Your Web Browser

I'm sure you've been there—halfway through typing something out, you realize that one word you've been using more than any other has been misspelled. Perhaps it's a single word, acronym, or line of code that you find yourself typing quite often at work, but this one requires complicated hand gymnastics that you'd simply rather not perform over and over again.
