When you see a color depicted on your computer, smartphone, or tablet, odds are it was processed as a hex triplet before it was rendered. Most modern websites and operating systems use a hexadecimal coding system to signify certain colors, and these are represented as 6 letters and numbers.
I once had a collection of over 300 different wallpapers for my MacBook, set to randomly change every 30 minutes. Needless to say, my desktop never got boring. Wallpapers can facilitate a mood, imply a political stance, or just add aesthetic appeal, so having to manually change them on my iPhone is a bummer because of how many times I want a new home or lock screen look.

Most of us know how to make a sandwich, but how many of us know how to make a sandwich correctly—i.e., so that the slippery ingredients like tomatoes and cucumber don't come gushing out the other end when we take a bite?
When exercising at a high intensity, you know to expect some level of pain. That can make it difficult to identify when your body gives you a warning sign of injury. If you pay close attention, however, you can tell the good hurt from the bad. I talked to Dr. Brian Parr again, professor at the Dept. of Exercise and Sports Science at the University of South Carolina Aiken, who explained which symptoms of exercise are normal and which are bad:
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.
With GPS chips and Wi-Fi positioning systems, a modern smartphone is capable of tracking its user's location with pinpoint accuracy. This being the case, it's strange that the most common text message sent today is still "Where are you?"
If you're one of the millions of people who use the WhatsApp service for messaging, you've probably noticed a recent propensity that the app has had for adding buttons to its interface. Two such buttons have made their way into the message thread screen, cluttering up the interface with functionality that is a tad bit redundant.
Real suffering is sitting through a thirty-second ad to watch a fifteen-second video, or watching your favorite music video in three-second fragments. Real suffering is this: “An error occurred, please try again later.” If you’re a modern human and multitask with multiple tabs while you're on YouTube, you don’t have to sacrifice your bandwidth and sanity. There's a simple way to watch YouTube ad-free and lag-free.
Remember those horrible, soul-crushing studies from a few years back linking grilled meats with cancer? Unfortunately, they're still true, but scientists have recently found that an unexpected ingredient can curb some of the harmful effects of high-temperature cooking.
There have been hundreds of reports of users hearing a grinding noise when they place a disc into their brand new Xbox One video game consoles. To prove it, here is an awesomely sad compilation of Xbox One owners having the issue.
Communication is the key to any healthy relationship, and when I say any, I mean human and non-human. Previously, one of the biggest culprits for not understanding what you meant was Siri, but now it looks like it has some competition with the new Kinect system, which can control practically everything on your Xbox One—if it can understand you.
It has been 7 long years since the PlayStation 3 was released, which makes it no surprise that over 1 million gamers purchased the new PlayStation 4 this weekend.
Welcome back, my aspiring hackers! As mentioned several times in previous Linux tutorials, nearly everything in Linux is a file, and very often they are text files. For instance, all of the configuration files in Linux are text files. To reconfigure an application in Linux, we simply need to open the configuration file, change the text file, re-save, and then restart the application and our reconfiguration is applied.
The worst thing about running shoes is that they're expensive, but you're supposed to abuse them. Even if you're not a runner, everyday wear and tear takes its toll. No matter how well you take care of them, if you use them enough, they're eventually going to wind up looking like this: And it's not just running shoes. I have a pair of Vans that I've worn for almost four years, and the heels are just about ripped all the way through.
There is nothing worse than losing valuable information or programs on your computer. And if you've ever accidentally deleted a file or document, you know how agonizing that entire process can be.
It only takes a minute for something well intentioned to turn into something sinister. Facebook created 'memorial pages' as way for friends and family to share their thoughts and feelings for those that are no longer with us.

RFID cards are becoming a fairly common way to purchase goods, but they're already widely used to pay fares on buses, trains, subways, and trolleys across various cities. TAP cards are quick and reliable, but it can be a real pain to remember to bring them with you, especially if you weren't planning on using public transportation that day. Luckily, an intrepid tinkerer at Adafruit has managed to find a way to embed an RFID card into her phone, something you're far less likely to leave at home.
There's a strange grey area for "guerrilla filmmaking" on YouTube. Generally, someone shooting a video needs to get permission from the people in it to show their faces. But on YouTube, that "rule" is more of a suggestion (and sometimes not even that).

The mother's body can be the source of delivery complications like placenta previa or uterine rupture. If delivery problems do occur, your doctor can usually help you manage these childbirth complications with medication or an emergency cesarean section.
This is NOT fake. To make someone faint, first have them squat down and breathe in deeply for about 10 seconds. Then, have them stand up straight against a wall and hold their breath. Get someone else to push hard against their chest. The person standing should then lose concsiousness for a few seconds! WARNING : This is dangerous and I am not responsible for any injuries/deaths that may occur. I do NOT encourage you to try this. Use this as inspiration for one of your April Fools Day pranks!

It may not seem like a big deal, but sometimes when your filenames are being saved in the incorrect case, it is. If you save a file with uppercase letters in the name, your computer may change them to all lowercase. This occurs when downloading files form a host server to a local hard drive. But what if you want them back how you had them? Well, there's a small Windows tweak you can use to stop it from happening. Learn how!
The tack is an important transitioning move that occurs when the nose of the board goes through the eye of the wind. Learning how to tack is key because it allows you to turn around. It is one of the most important transitions in windsurfing, allowing you to stay upwind and aid in your progression to using smaller boards in stronger winds. In this video, windsurfer Sam Ross shows you how.
This week, the beginning of an epic legal battle was set to begin between augmented reality players Magic Leap and Nreal, the small China-based startup accused by the former of stealing trade secrets.

OnePlus is one of the many partners that can now offer its users a chance to test the latest version early. That means you can install the newest Android Q beta right this second on your OnePlus 6, 6T, or 7 Pro just like Google's Pixel smartphones.
Switching phones has never been easier. Google backs up most of your app data on the cloud, which can then be restored onto your new phone. Sadly, Signal doesn't use this feature since it could compromise your security. Instead, Signal stores encrypted backups locally, requiring a bit of work to restore these messages.
Database technology has vastly improved the way we handle vast amounts of data, and almost every modern application utilizes it in one way or another. But the widespread use of databases naturally invites a slew of vulnerabilities and attacks to occur. SQL injection has been around for awhile, and as such, there are many defense methods in place to safeguard against these types of attacks.
Because augmented reality is still so new to so many people, there are a number of would-be experts opining online, often repeating basic facts anyone with a spare 15 minutes can find on their own. That's why it's important to point out when someone delivers what could be considered the ultimate cheat sheet for ramping up your AR IQ if you're unfamiliar with the finer points of the space.
Before, the only way to really tell how your iPhone's lithium-ion battery was performing was to use tools such as Geekbench and Battery Life, but now Apple has included some quick battery health checks right into iOS 11.
On June 11, 2016, an Arizona woman died from what appeared to be several infections, including pneumonia. She likely caught at least one of these from her dog.
More prescriptions for antibiotics are written for ear infections than any other type of infection. A new study comparing the incidence and causes of ear infections in children between the ages of six months and three years found that the incidence of ear infections over the last decade has dropped significantly since the 1980s.
When you have an infection, a doctor prescribes antibiotics to make the bacteria that causes it disappear. Sounds like a good idea, but the disappearance of microorganisms that have inhabited humans for millennia could be driving rising numbers of serious illness and debilitating conditions.
