The answer is complicated, and it depends on how much money you want to spend, how picky you are about sound quality, and a few other factors. There are ways to make an existing amp work with a sub, but the best results come from matching a subwoofer and an amplifier to achieve the harmony you desire. Who Needs a Subwoofer Amplifier? The short answer is that everyone who wants a subwoofer in their car also needs a subwoofer amplifier....

Bits, Bytes, and Prefixes All computers store data in a binary format as either a one or zero. Eight of these bits together form a byte. The various amounts of storage capacity are defined by a prefix that represents a specific amount, similar to the metric prefixes. Since all computers use binary math, these prefixes represent base-2 amounts. Each level is an increment of 2 to the 10th power or 1,024....

While these ads can be helpful in reminding you of products you may be interested in purchasing, they often clutter up content you do want to see and can slow down web page loading times. Online advertising is necessary to support websites and pay for expenses such as web hosting, compensation for writers and developers, and other costs. However, many people find online ads to be intrusive and annoying and prefer to turn them off....

HDR stands for High Dynamic Range, but it has nothing to do with those awful fairytale-looking photos of the same name. It’s a way of capturing a wider range of light (and dark), and then playing it back. It’s available on HDR TVs, but is a fairly new technology for mobile devices. Now, it’s available in the iOS YouTube app, but there are other apps that support it, too. “If you’re a producer, HDR video can elevate your work because it’s simply brighter and more colorful than standard video,” writes Engadget’s Steve Dent, describing an HDR project....

The Mac has way more power than the iPad and iPhone when it comes to automation. You can pretty much program it to do whatever you want. In theory. To use most of those tools—AppleScript, shell scripting, the supposedly user-friendly Automator—you have to be able to program. Shortcuts, on the other hand, is kind of like Legos for automation, in that anyone can pick it up and automate dull, repetitive tasks....

Earlier this week, Pine64 announced that it was working on an e-ink reader after years of fans asking for one. The PineNote, as it has been aptly named, is set to arrive sometime this year, and Pine64 says it should be one of the most powerful e-ink devices available when it launches. Set to retail at $399, the PineNote is a bit more expensive than some of the other e-ink readers that you might find available on the market today....

Zoom has a history of security and trust screwups, from installing secret web servers on your computer to lying about its number of daily active users. Now, Mac security researcher Patrick Wardle has discovered a flaw in the installer that leaves you open to exploitation. Given its track record, it seems likely that Zoom might have similar problems in the future, so how should you protect yourself? “Perhaps the marketplace will punish Zoom for the security breach, but this illuminates a much bigger issue in the cyberthreat arena....

The news about Meta is downbeat, which may signify the industry’s fate as the company is one of the top players in virtual reality. The company has invested billions in its Quest line of VR headsets to access the metaverse, a version of the Internet as a universal and immersive virtual world. Don’t believe the hype, some experts say. “For everyday users, VR offers an escape to another time and place—real or imagined,” Ryan Harmon, the president of Zeitgeist Design & Production, a company that produces immersive experiences, told Lifewire in an email interview....

Monitors using the new DisplayPort 2.0 spec already should be in stores, but COVID-19 canceled last year’s “plug tests.” These are in-person meetups where engineers from different companies hammer out interoperability issues. “VESA is now planning our next PlugTest for this Spring in Taiwan,” a Video Electronics Standards Association (VESA) spokesperson told The Verge, “so we expect to get this process rolling again.” DisplayPort 2.0 The big change in DisplayPort 2....

The problem is that ATT isn’t a block-all solution to trackers. If a user (you or I) opts out of being tracked by apps, then Apple disables its own built-in ad-tracking system, and requires developers to respect that decision and disable any other tracking software in their apps. What ATT doesn’t do is actually block those third-party trackers. For that, you need a third-party app—but you need to make sure you trust it....

Lean and light, AntiMalware tries to deliver top-notch protection without slowing the system down too much. With that said, we put this antivirus program through the paces and tested its performance, so read on to see our full thoughts. Type of Protection: Machine Learning AntiMalware 3....

Router manufacturers assign routers a default private IP address. The address 192.168.0.100 is not a common router address. Still, a few broadband router models and access points use it (as well as other devices), including some Netgear models and some printers by SerComm and USRobotics, among others. How Private IP Addresses Work Private network IP addresses cannot be accessed from the internet directly but can allow any device on a local network to connect to another device on that network....

This translator excels when you want to convert single words or phrases to see how they appear or sound in another language. It also works surprisingly well if you need to speak with someone when neither of you can understand the other language. Just type or speak, and then watch the translation appear off to the right. One of its best features is the ability to take any text you throw at it and accurately determine what language it’s in, and then instantly put it into a language you can understand....

The 502 Bad Gateway error displays inside the internet browser window, just like web pages do. What Does a 502 Bad Gateway Error Look Like? The 502 Bad Gateway can be customized by each website. While it’s fairly uncommon, different web servers do describe this error differently. Below are some common ways you might see it: 502 Bad Gateway502 Service Temporarily OverloadedError 502Temporary Error (502)502 Proxy Error502 Server Error: The server encountered a temporary error and could not complete your requestHTTP 502502....

In other words, 504 errors usually indicate that a different computer, one that the website you’re getting the message on doesn’t control but relies on, isn’t communicating with it quickly enough. Are You the Web Manager? See the Fixing 504 Errors on Your Own Site section further down the page for some things to consider on your end. How You Might See the 504 Error Individual websites are allowed to customize how they show “gateway timeout” errors, but here are the most common ways you’ll see one spelled out:...

Overall Findings At the end of the day, a mobile network and a fixed wireless access (FWA) network do exactly the same thing: provide access to the internet. However, like we discussed already above, the difference is that one of them lets you reach the internet from your phone while you’re out and about, while the other is only useful if you need internet at one place, like at home. Not all ISPs offer the same kind of 5G access, so knowing how they differ is important when choosing which provider to go with....

For example, if you were to enable 2FA on your Facebook account, you would be required to enter not only your login details but also a verification code whenever you’d want to sign in to your Facebook account from a new device. With 2FA enabled, however, Facebook sends an automatic text message to your mobile device during the sign-in process containing a verification code to enter in order to successfully log into your account....

What is a Dash Cam? So, what exactly does a dash cam do? A dash cam is essentially a way to record your driving whenever you go. With these recordings, you can prove fault in case of an accident, monitor your teenager learning to drive, and more. Not only that, but dash cams are getting increasingly affordable and easy to use, so they’re not limited to tech heads and early adopters....
