Why Stereo? Stereo provides a listening experience where sounds are placed across two channels to create a stage. Music mixing places some sounds to the left and others to the right of a primary listening position. Sounds placed in both the left and right channels (such as vocals) come from a phantom center channel between the left and right speakers. In short, it creates an audio illusion of sound coming from different directions....

Computer Requirements for Work-From-Home Jobs Probably the most important piece of equipment you’ll need is a computer. Unless the company you’re working with provides a system for you, you should keep in mind the computer specs you’ll need to meet your specific job requirements. For example, if your company requires remote workers to use a Windows computer but you go out and buy a Mac, you might find you can’t function the way you need to....

The Vive Pro 2 handily beats the Oculus on specs. As befitting a device that costs $799 and is geared to pro users, the Pro 2 offers 5K resolution, 120 Hz refresh rate, and a 120-degree field of view. These features should allow the Vive to offer significantly smoother video and a more realistic experience than most competitors when it’s released next month. Goodbye, Motion Sickness? As fun as it is to use, I’m still prone to “VR sickness” on occasion while using the Oculus....

When a car runs on software, it’s easy for an automaker to switch features on and off remotely. Then, it can charge a subscription for those features. That’s exactly what Toyota is doing with vehicles from 2018 onwards. Users will have to pay $8 a month or $80 a year for the Remote Connect service to enable the remote-start feature. “The initial reaction online was mainly confusion and anger that a feature that has been in most cars for years is now provided at extra cost in Toyotas,” AutoInsuance....

The tabs are: CPU: Shows the effects of processes on CPU activity Memory: Monitors usage of memory including the RAM physical memory Energy: Indicates the amount of energy used by each app Disk: Shows the amount of data read from and written to the disk Network Usage: Indicates which processes are sending or receiving data over your network...

The Trouble With Remote Car Starters and Manual Transmissions When you install an automatic starter in a vehicle that has an automatic transmission, it typically checks two things before starting the engine: that the transmission is in park and that the parking brake is set. In some installations, it will only check that the transmission is in park. The biggest problem with manual transmissions is that there is no park. They have only neutral, which is sort of like park, but the transmission is able to freewheel....

How to Use Facebook’s Built-In GIF Tool GIF files are short, repeating images often taken from video clips. They can also be homemade animations or just sparkly moving images. Facebook has its own built-in GIF tool that you can use to search for and easily insert GIFs into both your status updates and comment sections. Using GIF in Facebook Comments Inserting GIFs into comments on your friends’ posts is just as easy as inserting them into your own status updates — and you can do it both from the web and the app too....

Why Are Vacuum Tube Stereos Still Around? In the years following the end of the Cold War, the traditional vacuum tube became common in high-end audio products. With the U.S. firmly entrenched in the production of digital solid-state devices, countries that were previously behind the digital curve still had large tube manufacturing facilities. Those countries began producing and exporting vacuum tubes to the West. As a result, American manufacturers such as Audio Research, Cary Audio, ECP Audio, Glow Audio, Granite Audio, Jolida, Manley Labs, McIntosh, Rogue Audio, and others have tapped into this phenomenon....

If a font doesn’t display correctly in a document, the font file may be damaged. If a document won’t open, it’s possible one of the fonts used in the document is the problem. Using Font Book, you can test fonts for problems and remove them. You can also validate fonts before you install them to head off future problems. Validating fonts at installation cannot prevent the files from becoming damaged later, but it prevents you from installing problem files....

There are many other differences between the two, which should help you decide which cable and converters you may need to use. Overall Findings Video Graphics Array (VGA) was the standard video cable for computers when it was first released in 1987 and are easily recognizable by their blue 15-pin connectors. At that time, the supported resolution was 640x480, but eventually expanded in stages up to Ultra Extended Graphics Array (UXGA) in 2007....

A History of Video Game Emulators Video game emulators became popular in the 1990s with the rise of personal computers and the web, which allowed aspiring developers to work together and create software capable of emulating their favorite game consoles like the Atari 2600 and the Nintendo Entertainment System. The goal of emulation is generally to match the experience of using the original hardware, but many game emulators include extra features like options to integrate cheats, take screenshots, and create save states....

The VIVO VP01W is a low profile universal projector mount that’s designed for standard ceiling heights. It has a decent range of tilt and swivel motion, and can be rotated, but there is no height adjustment. Since it’s a universal mount, it can be used with most projectors that weigh under 30 pounds. We recently installed one of these mounts in a home theater setting to get some first-hand experience with how easy they are to install and adjust, how reliable they are, and how they hold up under real-world conditions....

High-performance EVs boast blisteringly quick acceleration, hit impressive top speeds, and exhibit excellent handling as well. Gasoline-powered vehicles offer stiff competition and benefit from over 100 years of accumulated research and development, but this is one race that might be tighter than you expect. How Do EVs Stack Up to Gasoline-Powered Vehicles? Electric and gas-powered vehicles come in lower-performance budget models, high-performance luxury models, and everything in between. There are many more gas vehicles on the road, which means there are more low-performance and high-performance gas models than electric vehicles, but electric vehicles have an advantage at both ends of the spectrum....

The American Automobile Association (AAA) suggests using contactless payments or gloves and a disinfectant at the pumps. “There are ways motorists can minimize touching surfaces when filling-up: using gloves/plastic bags or contactless payment are two options to consider," said AAA spokesperson Jeanette Casselano in an email. “Regardless, when touching the pump (and screen), we suggest using gloves or plastic bags as a barrier to touching the surface, using disinfecting wipes/hand sanitizer after filling up, wipe down the card as well....

What Are Expansion Slots Used For? The expansion card is plugged directly into the expansion port so that the motherboard has direct access to the hardware. However, since all computers have a limited number of expansion slots, it’s important to open your computer and check what’s available before you buy one. Some older systems require the use of a riser board to add additional expansion cards; however, modern computers not only usually have enough expansion slot options, but they also have features integrated directly into the motherboard, eliminating the need for so many expansion cards....

How Speakers Work Speakers make sound by vibrating, which is another way of saying sound is the product of tiny airwaves. To produce airwaves of a certain loudness or frequency, the speakers that produce those airwaves require a certain amount of power. Speakers that connect to an AV receiver are passive speakers, meaning they do not have a built-in power source, also known as an amplifier. Without connecting to an amplifier, the speakers have no source of energy to vibrate or “drive” the speakers and reproduce the sounds being fed into them....

Send an Anonymous Text With SMS Gateways The simplest way to text anonymously is to use SMS gateways, which only require an email address. All major carriers offer a service where your phone number also serves as an email address, and any emails sent to that address are delivered to your phone as a text. For example, if your friend’s number is 555-867-5309, and they’re on Sprint, you can send an email from your email address to 5558675309@messaging....

This is possible through Boolean operators such as AND, OR, NOT, and NEAR, as well as the symbols + (add) and - (subtract). When you include an operator in a Boolean search, you’re either introducing flexibility to get a wider range of results, or you’re defining limitations to reduce the number of unrelated results. Boolean Meaning George Boole, an English mathematician from the 19th century, developed an algebraic method that he first described in his 1847 book, The Mathematical Analysis of Logic and expounded upon in his An Investigation of the Laws of Thought (1854)....
