Pincushion distortion is most often associated with telephoto lenses, and in particular, zoom telephotos. The distortion will usually occur at the telephoto end of the lens. The pincushion distortion effect increases with the distance the object is from the optical axis of the lens. Fixing Pincushion Distortion Pincushion distortion can be corrected easily in modern image-editing programs such as Adobe Photoshop, which contains a lens-distortion correction filter. Free photo-editing programs also offer slightly less sophisticated corrections....

Similarly, for image and video files, bit depth is used to determine the resolution of a picture. The higher the bit depth — 24 bit versus 16 bit, for example — the better the image. Bit Depth vs. Bit Rate Bit depth is often confused with bit rate, but they are different. Bit rate, which is measured in kilobits per second, is the data throughput per second when sound is played back, not the resolution of each discrete sample that makes up the audio waveform....

PBX Functions Modern PBXs have several management features that make communication easy and more effective within organizations, helping boost productivity.

How Intermodulation Distortion Works Similar to Total Harmonic Distortion, Intermodulation Distortion is measured and represented as a percentage of the total output signal. And as with Total Harmonic Distortion, lower numbers are better for improved performance. Intermodulation Distortion can occur when two or more signals are mixed through a non-linear amplifier device. Each of the tones interacts with one another, producing altered (or modulated) amplitudes. This results in the formation of frequencies (often referred to as “sidebands”) not present in the original signal....

How Does Microsoft Continuum Work? Once you launch the Microsoft Continuum app, you can project your phone to an external monitor or big screen in one of two ways. You can use a wireless adapter to cast what’s on your phone with or without an internet connection, with your phone functioning as a virtual trackpad and keyboard. It’s good for web browsing and viewing photos, but not much else. The second option is to use a wired adapter like the Microsoft Display Dock to connect your smartphone to external peripherals like a monitor, mouse, and keyboard....

Running a 64-bit operating system on your computer is smart: it enables your computer to process data in 64-bit chunks, rather than the standard 32 bits, which leads to better performance. Get that same performance from iTunes by downloading the 64-bit version. iTunes Versions Compatible With 64-bit Editions of Windows 10, 8, 7, and Vista Download current or older versions of iTunes 64-bit directly from Apple: iTunes 12.10.11 (this is the current version of iTunes for 64-bit Windows) iTunes 12....

What Is Music Metadata? Music metadata is also referred to as ID3 tags, which are the containers that hold metadata information. These tags hold data such as a song’s title, artist, the album it came from, track number, genres, songwriter credits, and more. Metadata is at work whenever you search for a song on services like Spotify or Pandora, when a recommended song pops up for you, or when a record label pays an artist royalties, to name a few examples....

iFixit has discovered that attempts to replace the iPhone 13’s screen—a common smartphone repair—can completely disable FaceID. So unless your iPhone 13 is taken to an Apple store, a repair shop in Apple’s Independent Repair Providers network, or a shop with more advanced tools, you’re risking that functionality. The culprit is a small microcontroller chip paired with the phone’s screen, which has to be synced in order to work properly....

The remotes for both models are similar in their shape with the Fire stick remote being a little slimmer and more modern in its aesthetic....

How the Nagle Algorithm Works The Nagle algorithm processes data on the sending side of TCP applications by a method called nagling. It detects small-sized messages and accumulates those messages into larger TCP packets before sending data across the wire. This process avoids the generation of unnecessarily large numbers of small packets. The technical specification for the Nagle algorithm was published in 1984 as RFC 896. The decisions for how much data to accumulate and how long to wait between sends are critical to its overall performance....

The announcement was made on Apple’s Newsroom blog, where the company said it will apply the change globally in early 2022. A reader app refers to an application that provides content or a subscription to paying users. Netflix and Spotify are examples of reader apps. Prior to this change, Apple required developers to use its built-in payment system to be listed on the Apple Store. That way, whenever someone signed up for a subscription, Apple could collect a commission from the developer....

Why Are My Messages Not Showing a Contact Name on Apple Watch? Even if your contacts on your Apple Watch have worked in the past, a few issues could cause them to stop working. For example, a software update or even adding a third-party app from the App Store could make your contact names stop showing up, or it could make your contacts disappear completely. While it might seem like the update or the new app is to blame for the problem, more likely, there’s a problem with the syncing function preventing your contacts from syncing entirely from your iPhone to your Apple Watch....
