Wireless charging is pretty much ubiquitous among modern iPhones and Android smartphones, but the technology has brought a lot of clutter with it.
As businesses flocked to Zoom, Microsoft Teams, Google Meet, and other video conferencing platforms to bridge the gap, we wondered aloud -- why aren't more companies leaning even more heavily on augmented reality?
Choosing which programming language to learn next can be a truly daunting task. That's the case regardless of whether you're a Null Byter just beginning a career in development and cybersecurity or you're a seasoned ethical hacking and penetration tester with years of extensive coding experience under your belt. On that note, we recommend Python for anyone who hasn't mastered it yet.
Life is too chaotic to be organized all the time, but little steps in the right direction make things easier overall. File folders keep paperwork from spiraling out of control. Spice jars take the clutter out of cabinets. Storage totes keep basements neat and tidy. But to find what you're looking for faster, you need a label maker.
It seems like each day our phones become more integrated into our lives. School, work, shopping — so many tasks either require a phone or heavily benefit from one. But our phones are a double-edged sword that can easily distract us and harm our mental health as well.
A good smartphone can be the perfect workout companion. You have music for motivation, videos for pushing through boring cardio sessions, GPS to keep you on course, and even an array of sensors for gathering data about your workout. But not all phones are created equal when it comes to helping you stay fit.
While you might suspect your MacOS computer has been infected with malware, it can be difficult to know for sure. One way to spot malicious programs is to look for suspicious behavior — like programs listening in on our keyboard input or launching themselves every time we boot. Thanks to free MacOS tools called ReiKey and KnockKnock, we can detect suspicious programs to discover keyloggers and other persistent malware lurking on our system.
If you find yourself with a roommate hogging limited data bandwidth with video games or discover a neighbor has invited themselves into your Wi-Fi network, you can easily take back control of your internet access. Evil Limiter does this by letting you control the bit rate of any device on the same network as you, allowing you to slow or even stop data transfer speeds for them completely.
Nowadays, our phones are capable of just more than 30 fps video. Phones like the Galaxy S10 can shoot 4K at 60 fps, even on the front camera. Slow motion functionality has recently started to appear on more and more devices — but as you may have noticed, the quality of the feature differs from phone to phone.
Apple CEO Tim Cook has said that augmented reality (or, AR for short) will "change everything." But what, exactly, is augmented reality?
The Moto G7 Power is a phone that screams battery life. From its display resolution to the massive battery, it was designed for those who hate to recharge each night. But unlike other battery-focused smartphones, it comes at a price almost anyone can afford.
As intuitive as Google Maps is for finding the best routes, it never let you choose departure and arrival times in the mobile app. This feature has long been available on the desktop site, allowing you to see what traffic should be like at a certain time and how long your drive would take at a point in the future. Fortunately, Google has finally added this feature to the app for iPhone and Android.
You're minding your business when your Apple Watch taps you. To your surprise, the watch claims your heart rate dipped abnormally low. The news might come as a shock — especially if you have no history of a heart condition — but before you panic, you should take the time to fully understand what this alert is really saying and what you can and should do about it.
Apple Watch owners know the struggle — it's the end of the day, and those rings aren't met. Whether you forgot your watch before hitting the gym, let the battery run out, or just didn't move enough, you could feel the sting of fitness failure. But it doesn't have to be this way. You can actually close your Activity rings yourself; it just takes a little know-how.
Beginners learning brute-forcing attacks against WPA handshakes are often let down by the limitations of default wordlists like RockYou based on stolen passwords. The science of brute-forcing goes beyond using these default lists, allowing us to be more efficient by making customized wordlists. Using the Mentalist, we can generate millions of likely passwords based on details about the target.
In the Android community, Samsung's slow updates have long been the accepted norm. With the Note 8's recent Android Oreo update, Samsung completed annual version updates to their 2017 flagship lineup. Now is a great time to look back on how Samsung has fared with updates over the past few years. Hint: It's not pretty.
While Wi-Fi networks can be set up by smart IT people, that doesn't mean the users of the system are similarly tech-savvy. We'll demonstrate how an evil twin attack can steal Wi-Fi passwords by kicking a user off their trusted network while creating a nearly identical fake one. This forces the victim to connect to the fake network and supply the Wi-Fi password to regain internet access.
With over 1 billion downloads on the Play Store alone, Google Maps has become a staple for those traveling. Its popularity is the result of Google consistently improving its accuracy and adding new functionality. And this was only achieved with help of you — specifically, your data.
Unlike many browsers, Firefox gives a lot of control to the user. By default, Firefox does a great job of balancing security and performance. However, within the app's settings, you can modify options to shift this balance in one direction or another. For those looking to shift it toward security, here are few suggestions.
It's easy to have your password stolen. Important people like executives, government workers, journalists, and activists face sophisticated phishing attacks to compromise their online accounts, often targeting Google account credentials. To reduce this risk, Google created the Advanced Protection Program, which uses U2F security keys to control account access and make stolen passwords worthless.
When traversing the web, you'll regularly come across websites that require you to create an account. With the majority of these accounts, protection is limited to a simple password. Despite this, many people are still using weak passwords such "123456." For these reasons, you really need a password manager, and our research has shown that LastPass is still your best bet.
Speakers today are a marvel for their portability and sound quality. No longer do we need giant boxes to bring down the house — a speaker that can fit in your hand can fill a room with your favorite music. This is even more important when you pair it with your smartphone, and there are lots of smartphone-friendly speakers on sale this Black Friday.
So much information exists online that it's easy to get lost in data while researching. Understanding the bigger picture can take a lot of time and energy, but narrowing the question to one that's easy to answer is the first step of any investigation. That's why analysts use open-source intelligence (OSINT) tools like Maltego — to help refine raw data into a complete understanding of a situation.
Code execution in Microsoft Word is easier than ever, thanks to recent research done by Etienne Stalmans and Saif El-Sherei. Executing code in MS Word can be complicated, in some cases requiring the use of Macros or memory corruption. Fortunately, Microsoft has a built in a feature that we can abuse to have the same effect. The best part, it does so without raising any User Account Control security warnings. Let's look at how it's done.
Apple's iPhone 8 and iPhone X announcement went about exactly as the rumors predicted. Really, there was only one surprise — the fact that all of the new models will support the Qi wireless charging standard.
One of the most popular usages of modern-day smartphones is listening to music. It doesn't matter if you download or stream your tunes, you are part of a massive group of users who do exactly the same. While statistics are a bit foggy on how many smartphones users download music, we do know that over 68% of American smartphone owners stream music on a daily basis.

Just like your gastrointestinal tract, and the soil we walk on — a dust storm has a collection of bacteria, fungi, and viruses all its own called a "dust microbiome."
Most carmakers now agree with Waymo that piloting driverless cars is best left to the machine — with no meddling from the human.
Most people are familiar with the decline of honeybee colonies around the world. Among other threats, Colony Collapse Disorder (CCD) is eroding the capability of honeybees to maintain their hives and provide their services to human farmers.
There is an Indian story called the Legend of Paal Paysam, and while it doesn't seem like it at first, it has a lot to say about what motivated Paul Travers in the augmented reality space.
Apple has some great features aimed at making the lives of globetrotters and mall aficionados significantly easier, such as having detailed floor plans for airports and shopping centers in its native Maps app. With this feature available in Apple Maps, you no longer need to rely on publicly posted maps and directions that are often hard to understand.
One thing that I got more and more excited about as we got closer and closer to the Microsoft Build 2017 developers conference was finally learning about the new Acer Windows Mixed Reality head-mounted displays (HMD). Brandon Bray, Principal Group Program Manager at Microsoft, had teased us a few weeks earlier at the Vision Summit event in Los Angeles, California, and said there would be a lot more information at Build. Fortunately for us, he was right.
HIV-infected people who are treated long-term with antiviral drugs may have no detectable virus in their body, but scientists know there are pools of the virus hiding there, awaiting the chance to emerge and wreak havoc again. Since scientists discovered these latent pools, they have been trying to figure out if the remaining HIV is the cause of or caused by increased activation of the immune system.
A sometimes serious disease spread by fleas is making inroads in Texas, quietly doubling case numbers since 2008, and beginning to encroach on larger metropolitan areas.
For some of us, winter puts the brakes on apps like Pokémon GO since smartphone screens usually only respond to bare fingers. Nobody wants to be that guy who caught frostbite chasing a Sneasel. When you use normal gloves, the display's sensor simple doesn't activate, so that doesn't help any. Fortunately, several options for touchscreen-friendly capacitive gloves are on the market to help you through this last blast of winter.
While its direct-selling model echoes brands like Avon and Tupperware, Indonesia's MindStores gives the approach a modern twist—with augmented reality.
When it comes to busted smartphones, liquid damage ranks right up there with shattered screens as one of the most common issues owners have to deal with—as well as the most embarrassing. Thankfully, though, with the rise of waterproof phones such as the Samsung Galaxy S7 and even the iPhone 7, this is becoming less and less of a worry. But not everyone has a waterproof device.
