What Does a Crossover Do? If you’ve ever really looked at a speaker, you probably noticed that a single speaker unit has multiple, smaller speakers within. These are known as drivers. In most cases, these aren’t all handling the same frequencies, but instead focus on delivering a specific range of frequencies to work in concert with the other drivers. A crossover (also known as a speaker crossover or audio crossover) simply splits a signal between different speakers, like woofers and tweeters....

What is Doxxing? Doxxing (sometimes spelled doxing) is the gathering of personal information about individuals and releasing it on the internet. The intention is to cause the doxxed individual some sort of problem or embarrassment or to open them up to abuse and trolling from others. It’s a simple but powerful online threat to your privacy and, in some cases, to your safety. Doxxing is not new. The name comes from the term dumping documents....

Gurus and Freaks The English language is voracious. It absorbs words from other languages like a linguistic version of the Borg. The assimilated words sometimes stay true—or at least, close—to their original meanings like entrepreneur (French), glitz (Yiddish), and moped (Swedish). But often the word mutates into something rather different. The original meaning of guru (Sanskrit) is someone considered a master of a spiritual or religious doctrine, especially if they are a teacher, guide, and mentor to others....

The Wikimedia Foundation is seeking a sound that it wants people to associate with “the sound of all human knowledge.” The idea is to identify content coming from its different projects, such as Wikipedia, whenever visuals are not available — for example, if you ask your phone’s assistant for information on something and it pulls content from Wikipedia. Wikimedia said on the contest page, “with a sound logo, people will always hear the same sound when responses come from a Wikimedia project....

The sudden turns, brakes, and movement of roller coasters can apparently make an iPhone 14 or 14 Pro think that the owner was in an actual car crash. When the phone’s car crash detection feature is triggered, it will call emergency services and notify emergency contacts that you were in a crash unless you’re fast enough to stop it. The issue has been reported by several people across amusement parks in the United States....

Where to Access the Default Settings For each of the settings we list below, you’ll head to the same initial spot to make the change which is the Excel Options....

GPS Navigation There is no person in my life who I’m ruder to than the GPS navigation voice, whether it’s Google Maps or Apple Maps or whatever robot lady is trying to help. Think about it: This poor app is using advanced satellite technology to help me get somewhere fast, letting me know if there are delays or car accidents along the way. Yet when I ultimately have an idea of where I’m going, I will yell at it to shut up and quickly grab the phone to turn it off, without even saying “Thanks” or “Couldn’t have done it without you....

Photo by Benjamin Gustafsson Anytime you’re making connections to anything outside of your network, security should be a concern, and this is doubly true for users of BitTorrent, who are getting data from all sorts of unknown sources. Here’s how to protect yourself. Note: This is the third part in our series explaining BitTorrent—be sure and read the first part of the series, where we explained what BitTorrent is and how it works, and then the second part, where we explained how to create your own torrents....

What Is screen? Screen is a GNU utility (GNU is a large collection of open source software, and the bundling thereof into an operating system is commonly known as Linux) which allows you start one or more screens inside your terminal. You may ask why would I want to start a screen inside my terminal, and can you define screen better/further? Sure. Imagine that you are using a remote server of SSH and suddenly your network connection breaks, right in the middle of the database migration or production backup, which was running inside your terminal window....

Note-taking apps have made the practice of making notes instead of actually getting anything done way more artful. They can combine different types of content like handwritten notes and audio recordings onto one page, allow you to search your notes for key phrases, and can be synced across all devices. But unless you’re doing a Mission Control check before takeoff, are all these features necessary or just a distraction from actually doing stuff?...

We also assume that the attacker has either access to a domain-joined computer or has access to the network. 1. Escalating to the SYSTEM Account Escalating privileges to the local system account on the computer is, in many cases, the first thing that an attacker needs to do. The attacker can use a wide range of techniques to perform the escalation, and some of them are summarized here. Of course, you’ve done half the job for the attacker if the user already has local admin on the computer....

After you setup Remote Access on your Windows Home Server, you’ll be able to access its shared files and folders from virtually anywhere. For this article we’re accessing WHS from an iPod Touch running iOS 4.0, but you can access it from any smart phone, tablet, Android device, computer…essentially any device with Internet access. The server we are using is a home built machine, and we’ll look at getting basic access to your documents through the Safari browser....

If you’re hosting web services on a cloud server, such as GCP’s Compute Engine, you probably want to use a static public IP address, as the default dynamic one is subject to change whenever the server is restarted. What Is a Static IP Address? Whenever you launch a server on any virtual cloud provider like AWS or Google Cloud Platform, it’s assigned two IP addresses—a private address for communicating internally, and a public address that allows anyone on the web to access services running on the machine, provided the firewall is open....

Caching is the process of storing downloaded data for later use, where it can be read from disk rather than requesting it again. Making proper use of your browser and CDN caching can speed up your website significantly. How Does Caching Work? Every user’s browser has a built-in cache, which stores static objects downloaded from websites. The next time they connect, if the object they’re requesting is still in the cache, it will load from memory rather than asking for it again, speeding up performance significantly and reducing the load on your web server in the process....
