Can You Use a Projector as a TV? While a projector can easily stand in for television for most functions, they aren’t entirely interchangeable. The most significant difference is televisions have built-in TV tuners, which allow them to receive over-the-air broadcasts. So while you can easily use a projector instead of a TV to play video games, stream movies and shows, and other activities, the crucial act of watching broadcast television requires additional hardware....

What is a Boolean Value? A Boolean value, which is sometimes called a logical value, is one of several types of data used in spreadsheets in applications like Excel and Google Sheets. Named after the 19th-century mathematician George Boole, Boolean values are part of a branch of algebra known as Boolean algebra or Boolean logic. Boolean logic is vital to all computer technology, not just spreadsheet programs, and rests on the concept that all values can be reduced to either TRUE or FALSE—or, because computer technology is based on the binary number system, either 1 or 0....

What is the DATEVALUE Function? The DATEVALUE function in Excel converts a text-formatted date into a serial number. Excel can then read the serial number to understand the date. This Excel function is necessary when a cell contains date information but it’s stored in regular text.

This can happen if the date has been copied or imported from elsewhere....

Virtual reality applications aimed at the fitness crowd range from boxing to all manner of exercises in virtual environments. But while the images may be virtual, the sweat is real, and there’s even some science behind the idea. A recent paper in the British Journal of Health Psychology found that exercisers feel better when they immerse themselves in music and computer-simulated environments. “It was quite striking how the combination of virtual reality with music boosted exercise-related pleasure, compared with just music or control conditions,” one of the paper’s co-authors, Costas Karageorghis, a professor at Brunel University London, said in a news release....

There are almost as many ways to take notes as there are people taking them. Some prefer paper, while others (the monsters) will just keep adding to a single Microsoft Word document. But let’s be honest—most people use the Notes app built into their computer or phone. For Apple users, that app just got a huge power-up in the form of Quick Notes, and it’s possible you’ll never lose a note again....

What Is Open Wi-Fi? It’s not safe to connect to an unknown open wireless network, particularly when transferring sensitive data, such as an online banking password. All information sent over an unsecured wireless network—one that doesn’t require a Wi-Fi Protected Access (WPA), WPA2 or WPA3 security code—is sent in plain text for anyone to intercept. The Risks of Using Unsecured Wi-Fi Networks When signing in to a website or using an application that sends data in clear text over a network, anyone so inclined can capture that information....

What Does ‘Connection Is Not Secure’ Mean? Browsers will return a “connection not secure” error when they can’t verify a website’s SSL certificate. SSL is a secure data-encryption method that keeps transmitted data private and safe. If a browser detects a problem with a site’s SSL certificate, it won’t load that site because it might be unsafe. While all this can sound very alarming, it’s likely that nothing is wrong....

Fernando is the founder and CEO of OxiWear, a vital-monitoring and emergency-alert accessory worn on the ear. The device can monitor a person’s oxygen levels, notify them when those levels dip too low, and alert the proper medical authorities if need be. Her health condition came as a result of an untreated atrial septal defect, a birth defect resulting in a hole near the heart. Fernando said she had experienced breathing problems her whole life, yet doctors simply diagnosed her with asthma as a kid....

The HDR Factor One “techie” term that has entered the TV mix is HDR. HDR (High Dynamic Range) is all the rage amongst TV makers, and there is a good reason for consumers to take notice. Although 4K has improved resolution, HDR tackles another important factor in both TV and video projectors, light output (luminance). As a result of HDR implementation, two established technical terms have risen to prominence in TV and video projector promotion: Nits and Lumens....

Despite having their choice of more than a few VR headsets, many still feel the pressure to purchase the most expensive option, thinking it will deliver the best VR experience. While the pricier head-mounted displays add a few extra bells and whistles, ultimately, VR can be enjoyed without spending thousands of dollars on the fanciest headsets. “You can absolutely enjoy VR experiences with a less-expensive headset,” Amy Peck, an AR/VR strategist and CEO of EndeavorVR, told Lifewire in an email....

Apple wasn’t the first company to make true wireless earbuds, but it set the standard and price point with the original $160 AirPods—and then opened up the floodgates for competitors to produce their own oft-similar renditions.

OnePlus threw its hat in the ring with the $80 OnePlus Buds, but now they’ve hit an even sweeter spot with the newer OnePlus Buds Z....
