Over the years the iPod Touch has evolved from a fun, but limited iPod to a powerful device that could almost replace an iPhone for some uses. This article tracks the evolution of the iPod Touch by covering the history, features, and specs of every generation of the iPod Touch. The iPhone ​had been out about 18 months when the first iPod Touch was released. The iPhone 3G had debuted a few months earlier and, by this time, Apple knew it had a hit on its hands with the iPhone....

It’s official, the previously-rumored iPad Pro actually exists, and it’s bringing along a friend in the new 10th Generation iPad. The new iPad Pro does indeed utilize Apple’s M2 chip, as many were anticipating, while the 10th Gen iPad boasts a 10.9-inch all-screen display. Of course, there’s more to both of the new iPads than what’s on the surface. Between the M2 chip, CPU, and GPU, the new iPad Pro claims vastly improved performance over M1 devices and a particular knack for machine learning and multitasking processes....

Spanish and Iranian researchers have proposed using the heartbeat as a biometric tool by recording its musical features, such as rhythm, and pitch, to uniquely identify people. In tests, the system managed to achieve a 99.6 percent accuracy rate. “We might use this solution in a building’s access control system where pre-registered users provide a template (a short ECG recording) to enter the facilities,” write the researchers in their paper illustrating a use-case for their heartbeat-based biometric system....

But here are five of the biggest obstacles HD Radio is facing. To compare, in 2012 about 34 percent of Americans reported listening to internet radio—including services like Pandora as well as online streams of AM and FM stations. Only 2 percent reported listening to HD Radio. Another issue is the slow adoption of HD Radio broadcast technology by stations. If you live in an area with good HD Radio coverage, then this isn’t an issue....

Octets vs. Bytes All modern computer systems implement a byte as an eight-bit quantity. Octets and bytes are the same from this perspective. For this reason, the two terms are used interchangeably. Historically, however, computers have supported bytes having different numbers of bits; octets and bytes mean different things in this context. Network professionals began using the term octet many years ago to maintain this distinction. Computer systems engineers often use the term nibble when referring to a four-bit quantity (half of one octet or byte) rather than calling it a half octet (or quartet, as is common in music)....

What Are TIF and TIFF Files? A file with the TIF or TIFF file extension is a tagged image file. This type of file is used for high-quality raster type graphics. The format supports lossless compression, in which no image data is lost during the compression process. This lets graphic artists and photographers archive their high-quality photos in a manageable amount of storage space without compromising quality. GeoTIFF image files also use the TIF file extension....

Can You Get Better Bass in a Car Without an Amp or Subwoofer? The cold, hard truth is that you’re not going to get really good bass in a sound system that doesn’t include both a subwoofer and an amplifier to drive it. The issue is that car speakers, even really good car speakers, aren’t big enough, and built-in car stereo amps aren’t powerful enough, to reproduce deep, distortion-free bass. That being the case, upgrading your stock car speakers can still yield some pretty powerful results....

Tighten Everything Before Packing Make sure all the covers are tight on the camera before packing it: USB ports, lens caps, battery compartment panel, etc. Jostling and bumps can tear off or break loose parts. Remove the Lens If you’re flying with a DSLR camera, don’t travel with the lens attached to the camera body. Shifts during the flight can stress or damage the threads that hold the lens to the camera....

For 720p and 1080p HDTVs, the optimum viewing distance is about 1-1/2 to 2 times the width of the television screen. This means that if you have a 55-inch TV, you should sit about 6 to 8 feet from the screen. If you sit too close to a TV screen, (although you won’t damage your eyes), there is a greater chance that you may see the line or pixel structure of the image, along with any processing artifacts, which can not only be distracting, but uncomfortable....

Troubleshoot Font Installations When you add a new font to your computer, follow the steps to download the font, expand the font archive, and install it. When an application, such as a word processor like Microsoft Word, doesn’t recognize the font, it might be broken. Some font problems can be fixed by deleting and reinstalling the font. If the font still doesn’t display properly, follow these troubleshooting tips. What Is an OpenType Font?...

Overall Findings Both a TV and a monitor provide high-definition displays for movies, games, and productivity. There’s overlap in terms of price, size, and functionality. Which one you use depends on your preferences and needs. TVs and monitors can work together to give you an extra screen for your computer or a bigger display for presentations and media. Size: HDTVs Provide More Screen Overlap exists between the sizes of TVs and monitors....

Twitch officially responded to the leak Wednesday, citing a server configuration change as the reason the hackers were able to access the site’s information and steal its source code. Twitch also says the investigation is ongoing, and at this moment there is no indication that login credentials were taken in the breach. Additionally, Twitch says full credit card numbers are not stored by the site, so users shouldn’t worry about their full card numbers being exposed by the hackers responsible for the leak....

Stated Power Ratings Can Be Deceiving When it comes to real amplifier power output, especially with surround sound receivers, you can’t take a manufacturer’s amplifier power rating statements at face value. You need to look closer at what they base their statements on. For example, for home theater receivers with a 5.1 or 7.1 channel configuration, is the stated wattage output specification determined when the amplifier is driving one or two channels at a time?...

Printer DPI Is Dots Per Inch Printers print by applying ink or toner onto the paper. Inkjets use nozzles that spray tiny drops of ink, while laser printers melt dots of toner against the paper. When more dots are squeezed into a square inch, the resulting image is sharper. A 600 dpi printer squeezes 600 dots horizontally and 600 dots vertically in every square inch of the sheet. Some inkjet printers have a higher resolution in one direction, so you might also see a resolution like 600 by 1200 dpi....

Isolation is an integral part of database transactional properties. It is the third property of the ACID (Atomicity, Consistency, Isolation, Durability) standards that ensure data remains consistent and accurate. How Isolation Works If Joe issues a database transaction at the same time that Mary issues a different transaction, both transactions should operate on the database in an isolated manner. The database should either perform Joe’s entire transaction before executing Mary’s or vice-versa....

What is USB? The Universal Serial Bus standard has been extremely successful. USB ports and cables are used to connect hardware such as printers, scanners, keyboards, mice, flash drives, external hard drives, joysticks, cameras, monitors, and more to computers of all kinds, including desktops, tablets, laptops, netbooks, etc. In fact, USB has become so common that you’ll find the connection available on nearly any computer-like device such as video game consoles, home audio/visual equipment, and even in many automobiles....
