It’s got three programmable buttons and a delightfully smooth scroll wheel. As someone who has suffered from repetitive stress injury (RSI), I’m always looking to switch up my mousing game. A wise physical therapist once told me that regularly changing up your pointing device is key to preventing RSI....

For the headline iOS 15 features, either take a look at Apple’s overviews or check out Lifewire’s own posts on the new OS. There’s a lot there, but there’s even more under the hood, from a huge revamp of keyboard shortcuts, to translations everywhere, to the amazing Siri Knowledge. “Almost all iOS 15 features that didn’t get any stage time during the keynote were mostly about polishing the rough edges....

What Is Roblox? Roblox is a trendy, international, free, online game platform. So, while it’s easy to think of it as a single game, it’s really a platform. That means folks using Roblox create their own games for others to play. Visually it looks like a marriage of LEGO and Minecraft. Is Roblox a game? Yes, but not precisely. Roblox is a game platform that supports user-created, multi-user games. Roblox refers to this as a “social platform for play....

Because each disk has less to do and writes to each disk occur concurrently, it takes less time to write the data. The same is true when reading data; instead of a single disk having to seek out and then send a large block of data, multiple disks each stream their part of the data stream. As a result, RAID 0 striped sets can provide a dynamic increase in disk performance, resulting in faster OS X performance on your Mac....

Causes of Mac Hardware Failures Some Mac issues, such as those involving startup problems, can be caused by software or hardware issues. A good example is getting stuck at the blue screen or gray screen when you start a Mac. The reason the Mac is stuck could be a hardware or software problem. Running the Apple Hardware Test can narrow down the cause. Apple hardware fails from time to time, with the most common failure being RAM....

The most obvious difference between the Apple Watch and Google’s new Pixel Watch is the shape. Google’s is round, but it’s also very similar. Google copies Apple’s digital crown; pressing the side button brings up a list of recent apps; the watch is laser-focussed on fitness. This is good news for Android users who want a Pixel version of the Apple Watch, but not so great for people who want a different take on the wearable computer....

However, if BIOS encounters an issue but hasn’t booted far enough to be able to display a POST error message on the monitor, a beep code—an audible version of an error message—will sound instead. Beep codes are especially helpful if the root cause of the problem has something to do with video. If you can’t read an error message or error code on the screen because of a video-related problem, it’s definitely going to deter your efforts of finding out what’s wrong....

What Is a TAR File? Short for Tape Archive, and sometimes referred to as tarball, a file that has the TAR file extension is a file in the Consolidated Unix Archive format. A program or command that can open archives is needed to open a TAR file. Because the TAR file format is used to store multiple files in one single file, it’s a popular method for both archiving purposes and for sending multiple files over the internet, like for software downloads....

A drive’s volume label can be changed at any time, but is usually set during the formatting of the drive. Volume Label Restrictions Certain restrictions apply when assigning volume labels, depending on which file system is on the drive—NTFS or FAT: NTFS Drives Maximum of 32 charactersNo tabs FAT Drives Maximum of 11 charactersNo * ? . , ; : / \ | + = < > [ ]No tabs...

How Do Automatic Braking Systems Work? Each car manufacturer has its own automatic braking system technology, but they all rely on some type of sensor input. Some of these systems use lasers, others use radar, and some even use video data. This sensor input is then used to determine if there are any objects present in the path of the vehicle. If an object is detected, the system can then determine if the speed of the vehicle is greater than the speed of the object in front of it....

What OLED TV Is OLED stands for Organic Light Emitting Diode. OLED is an outgrowth of LCD technology that uses organic compounds formed into pixels to create images, without the need for extra backlighting. As a result, OLED technology allows for very thin display screens that are much thinner than traditional LCD and plasma screens. OLED is also referred to as Organic Electro-Luminescence. OLED Versus LCD OLED is similar to LCD in that OLED panels can be laid out in very thin layers, enabling thin TV frame design and energy efficient power consumption....

Uplink vs. Downlink A downlink is a connection made in the opposite direction of an uplink, either from a satellite to the ground or from an outside network into a local network. Internet downloads, for example, travel over a downlink to the downloading device, while internet uploads travel over uplink connections. Uplinks are commonly used in satellite telecommunications to broadcast satellite radio and television. Broadcasters transmit signal feeds from ground stations to the orbiting satellite, a process known as satellite uplink....

HFS+ and HFS (an earlier version of the Hierarchical File System) were created in the days of floppy disks, the primary storage medium for the Mac back when spinning hard drives were an expensive option offered by third parties. Apple flirted with replacing HFS+ over the years. Eventually, APFS, which is already included in iOS, tvOS, and watchOS, became the default file system for Macs running macOS High Sierra and later....

There are multiple reasons to use cloud storage services. Maybe your local hard drives are running low on disk space, in which case you can use the cloud as extra storage. If you want to be able to stream your music collection from anywhere, access your work files at home, easily share vacation videos, etc., you can upload your files online to a cloud storage service. Another reason to use cloud storage is if you want to keep important files secure behind a password and encryption....

What Is ENIAC? ENIAC is an acronym for Electronic Numerical Integrator and Computer. Also known as The Giant Brain, it was the first programmable general-purpose electronic digital computer. In the 1940s, physicist John Mauchly began working on his concept for an electronic calculating machine while teaching at the Moore School of Electrical Engineering at the University of Pennsylvania, which was a center for wartime computing. The U.S. Army needed a faster computer to calculate the trajectory of artillery shells during World War II, and funded his work to develop such a machine....

The tools are easily accessible for users of any experience level (i.e., you don’t need to be an expert in 3D design to know how to use it). Plus, it’s also perfectly functional as a 2D program and works much like the classic Paint program, only with more advanced features and an updated user interface. Paint 3D serves as a replacement for the older Paint program. How to Download Paint 3D Paint 3D is available only on Windows 11 and Windows 10....

What Is Samsung DeX? Dex extends the Android Multi-Window or split-screen mode, allowing you to multitask easily between apps, tools, and devices. In DeX mode, you can see your full list of apps, access an on-screen keyboard, search for apps and items, and access and edit your phone’s photos and files. You can also reply to text messages and take calls. DeX is not a full-fledged desktop replacement. It’s a companion that is slower and less dynamic than a traditional desktop environment....

The word originally referred to the association between software code and genetic code, where an organism’s DNA, which is physically wet, resembles software instructions. In other words, wetware references the software that belongs to a living organism—the instructions contained within its DNA, similar to how the instructions behind a computer program are called its software or firmware. Computer hardware can be contrasted with a human’s “hardware” like the brain and nervous system, and software can refer to our thoughts or DNA instructions....
