Battery chargers and even portable generators are great to have on-hand, but what do you do when the battery bank runs out of power and the portable generator runs dry on fuel when you don’t have an outlet or gas station nearby? You use a portable solar charger, like the BigBlue 28W Solar Charger. Sure, this notebook-sized charger won’t power a fridge or toaster, but for times when you need a little extra juice in your phone in emergency situations or while out camping, folding solar panel chargers are a great solution....

Now, since the advent of the full-screen gauge cluster, analog gauges have given way to increasingly crowded slabs of information wrapped in overdesigned insanity. In a rush to brand themselves, some automakers have taken the one area in the car that should be reserved for only the most relevant information needed to pilot a vehicle safely and, in some cases, made it into a designer’s playground. Not the clean minimalism we actually need, but something eye-straining....

Why Siri Only Runs on Apple Devices Siri will probably always only work on iOS, iPadOS, and macOS because Siri is a major competitive difference for Apple. If you want all the cool things Siri does, you have to buy an iPhone or other Apple device. Apple makes the largest part of its money on hardware sales, so allowing such a compelling feature to run on its competitor’s hardware would hurt its bottom line....

Experts recognize Shaw, creator of side-scrolling arcade title River Raid, for her influence on the gaming industry during a time when men dominated the business (even more so than now). “I think she really helped paved the way for [the] female game designers that came later,” Julia Novakovic, archivist at The Strong National Museum of Play, told Lifewire in a phone interview. “She proved that women were not only exceptional programmers, but that they also deserved recognition for their work....

Each member of this group does a slightly different job, and the Count() function’s role is to count only numbers. It can do this two ways: What Is a Number in Excel? In addition to any rational number — such as 10, 11.547, -15, or 0 — other types of data are stored as numbers in Excel. The Count() function will count these as well if included with the function’s arguments....

What Is a DBF File? A file with the .DBF file extension is most likely a Database file used by the data management system dBASE. Data is stored within the file in an array with multiple records and fields. Since the file structure is pretty straightforward, and the format was used early on when database programs first arose, it’s been considered a standard format for structured data. Esri’s ArcInfo stores data in files that end in ....

What Is the Difference Between an Email Header and Email Body? When you think of traditional mail, the two parts are easy to see. With paper mail, there’s the envelope with the address, stamp, and postal information on it, and the letter or other paperwork inside. With email, it’s similar. There are also two distinct parts that make up a single email message. There is the header with control information and other data, and the body of the message which includes the sender’s text, as well as attachments and other components....

Via internet streaming and Ultra HD Blu-ray Disc. Limited broadcasting is expected to start in 2020; standards have already been adopted for 4K over-the-air TV broadcasts. However, it will be a couple of years after that before routine broadcasts and a sufficient number of TVs with tuners that can receive them will be available. On cable, things are progressing slowly as Comcast and Altice are the only major cable services offering 4K which includes access to Netflix 4K streaming content and limited special event programming....

What Is a DMA File? A file with the DMA file extension is most likely a DOORS module archive created with IBM Rational DOORS. If your file isn’t in that format, our next best guess is that it’s a DMOD audio file. How to Open a DMA File DOORS module archives can be opened with IBM Rational DOORS. DMA files that were created in an older version of the software should be able to open in newer versions through the File > Restore > Module menu....

Do Wi-Fi Extenders Work for Gaming? Yes, they do, but they aren’t the ideal solution. Generally, playing games via a Wi-Fi connection isn’t as effective as plugging your games console directly into a router. That’s because a hard-wired solution gives you much lower latency. Adding Wi-Fi extenders makes the latency even higher than simply using a Wi-Fi router, which can affect a game’s performance when playing something fast-paced online. Lag is more commonplace when using a Wi-Fi extender, especially if you use a cheaper, low-quality device....

Can I Use Alexa Without Wi-Fi? The processing power and storage available on Alexa devices are very limited, so most of Alexa’s functionality relies on an internet connection provided via Wi-Fi. That can be a standard Wi-Fi network like you have at home that uses your home internet connection, mobile data from a dedicated hotspot device, or a phone set up to work as a hotspot. Can Alexa Work With Mobile Data?...

This SIM card is virtually the same as the SIM card found in many smartphones. In the past, SIM cards were often tied to a particular carrier. As a result, some iPads were locked in to a specific carrier by a SIM card that didn’t work with other carriers unless the iPad is jailbroken. What Is the Apple SIM Card? And Do I Have One? If you think it was inconvenient for every SIM card to be tied to a specific telecom company and every iPad to be locked into that company, you are not alone....

5G’s Massive Speed Boost At speeds that are theoretically 20 times faster than 4G, 5G’s main selling point is definitely its speed. Apple says that iPhone 12 users can, in ideal conditions, expect download speeds that are twice as fast as what you’d get with 4G: 4 Gbps with 5G and 2 Gbps with 4G LTE. However, there are three types of 5G that are available to you depending on where you are and who your provider is: low-band, mid-band, and mmWave....

For years, Mac users moaned about iTunes, hoping for a simpler, less-bloated replacement. In a textbook case of “be careful what you wish for,” iTunes’ replacement was even worse. Even the name—Music—is confusing. Doppler is a glimpse into an alternate future where Apple put user experience first, instead of trying to encourage sign ups for Apple Music subscriptions. “Apple has been melding its Apple Music service with the basic music-library player functionality with an eye towards pushing users to use Apple Music,” Mac app developer Edward Brawer told Lifewire via email....

Overall Findings For many, Google is like the slightly unpleasant co-worker everyone puts up with because they do a good job. The degree to which Google tracks you is as astonishing as it is endemic to the use of its services. DuckDuckGo has been at the privacy game for years. DuckDuckGo’s claim to fame is that it tracks (nearly) nothing about you. But this could affect its search abilities. Search: Powerful Results Google’s searches are unquestionably top-notch....

The Enclave Audio CineHome aims to remove the tedium and stress of wiring a surround sound system by doing away with those cumbersome lengths of cord, syncing your speakers via wireless connections instead. The allure of a wireless house is a siren song to many—wires, cables, and cords of all descriptions are an eyesore and a frequent point of failure. Sadly, at least in the case of the CineHome, that glorious wireless future hasn’t quite fully arrived yet....

Video doorbells in the range of the Eufy T8200 are a good option for those who want something a bit more affordable. Compared to the latest offerings from Ring and Google Nest, the Eufy T8200 is around two-thirds the price, and it doesn’t require a monthly subscription service for storage and advanced features. To see if this doorbell is really as great as it sounds, I tested the Eufy T8200 for a week, evaluating its design, ease of installation, features, video quality, audio quality, app, and price....
