How to Share Your Mac’s Screen Using Messages

Mac-Screen-Sharing-Cover.jpg macOS users can use iMessage to send and receive messages from other Apple users. But the Messages app allows for greater functionality than you might know. One of the features is the ability to share your screen with another user. This will save you the effort of having to install third-party apps to remotely access another Mac. Here is how to share your screen with other with the Messages app. Note: it’s recommended to share your screen only with someone you know and trust, as sharing your screen allows others to control your computer and access your files and data, too….

How to Use All Linux’s Search Commands

Concept of a Linux terminal full of text on a laptop

Linux offers six different ways to search, and each has its merits. We’ll demonstrate how to use find, locate, which, whereis, whatis, and apropos. Each excels at different tasks; here’s how to choose the right tool for the job.

You’re spoiled for choice when it comes to commands for searching and finding in Linux. Why so many? Well, they each have their specialties and perform better than the others in certain circumstances. You could think of them as a sort of Swiss-Army knife for searching. We’re going to look at each blade in turn and find out its particular strengths.

The find Command

The behavior of the find command is difficult to determine by trial and error. Once you understand the syntax, you start to appreciate its flexibility and power.

The simplest way to use find is to just type find and hit enter.

Used in this way find behaves like ls, but it lists all of the files in the current directory and those in subdirectories.

Some implementations of find require you to put the . for the current directory. If this is the case with your version of Linux,  use the following command:

find .

TwitterFacebook

Slack is having problems on a Friday, a sure sign from the gods that you should leave work, throw your laptop into a burning pyre, and return to a feral state in the wild until at least Monday. 

Users have described problems with messages not sending, or double-posting. 

“We received reports of multiple issues regarding Slack’s degraded performance, which we are currently investigating,” Slack said on Friday morning. 

According to Down Detector (which is owned by Ziff Davis, the parent company of Mashable), there have been issues in Europe, Japan, and both coasts of the United StatesSlack Status says there are currently problems with messaging, file uploads, calls, notifications, and more.  Read more…

How to See All Your Saved Wi-Fi Passwords on Windows 10

Wireless router on tableMayuree Moonhirun/Shutterstock.com

Windows remembers every Wi-Fi password you’ve ever used. That’s how it reconnects to those networks. Here’s how you can view the saved password of any network you’ve ever connected to on your Windows PC.

Download NirSoft’s WirelessKeyView

You can view saved passwords with built-in command-line tools in Windows, but we recommend NirSoft’s free WirelessKeyView application. It’s a lightweight tool you don’t even have to install to use—just download it, open the ZIP file, and then double-click the included EXE file. You’ll then see a list of saved network names and their passwords stored in Windows.

The “Network Name” column shows the name of the Wi-Fi network—in other words, its SSID. To find the password associated with a network, look under the “Key (Ascii)” column for that network name. This is the password you type to connect to that network.

To back up this information, you can select File > Save All Items. You’ll get a text file containing this information, so you can take it with you to a new PC or store it for later.

NirSoft WirelessKeyView running on Windows 10

Use the Command Line

Windows 10’s standard Control Panel only lets you see the password of the Wi-Fi network you’re currently connected to. If you don’t want to download third-party software, you’ll have to use command line tools to discover this information.

To find a password on Windows without third-party software, open a Command Prompt or PowerShell window. To do this, right-click the Start button or press Windows+X, and then click “PowerShell.”

Run the following command to see the list of saved network profiles on your system:

netsh wlan show profiles

How Do Bone Conduction Headphones Work?

A man wearing AfterShokz bone conduction headphones. He looks very thoughtful. Perhaps he's listening to a podcast.AfterShokz

If you haven’t heard of bone conduction headphones, then prepare yourself for something weird. They’re ultraquiet, they don’t sit on (or in) your ears, and they vibrate your skull. But how can you hear sound through your skull?

Sounds Are Just Vibrations

Before diving into bone conduction, let’s first look at how sound works. Like light, sound travels through the air in waves. But unlike light, sound can also travel through dense objects. This is why sounds are usually referred to as “pressure waves.” They cause objects to vibrate, even if you can’t see it.

There are a bunch of tiny organs in your ear designed to react to sound. In other words, they’re great at vibrating. The star of the show is your eardrum, which is a thin flap of skin that vibrates like the head of a drum or the diaphragm of a microphone. It encourages your other ear organs and tiny ear bones to vibrate. (As a side note, don’t look up pictures of the eardrum. It’s gross.)

Once everything starts shakin’, your cochlea looks around and records what’s going on. It then sends that data to the brain, where it’s translated into music, voices, or any other noise that you’re subjecting yourself to.

So far, it seems like hearing is a relatively simple process. And guess what? Bone conduction is just as simple.

Bone Conduction Skips Your Eardrums

Alright, so typical hearing depends on the eardrum to vibrate all of the little organs and bones of your inner ear. The eardrum isn’t necessary for hearing, but without it, your inner ear bones and organs would be static.

See where this is going? Bone conduction bypasses your eardrum by sending vibrations to your inner ear through your skull. Once all the tiny bones and organs of your inner ear start moving, your cochlea doesn’t know the difference. It records the vibrations, sends them to the brain, and you suddenly hear music, podcasts, or the obnoxious videos that automatically play on news websites.

Now, this doesn’t mean that bone conduction headphones are totally silent. They’re still audible (a lot less audible than earbuds), but they’re designed to push sound waves through your skull, rather than through the air.

Why Use Bone Conduction Headphones?

Again, bone conduction headphones skip the eardrum and don’t push much sound into the air, so they have several practical uses. For one, you can use them to free up your ears while exercising, talking to people, or listening for traffic. You can also use them to avoid the harmful sound levels of typical headphones. They’re essentially the opposite of noise-canceling headphones.

It’s Used on Nearly Every Server Linux is the standard for servers. There’s no way around it. Linux has long been the most popular HTTP server software, and it’s built firmly on top of the Linux kernel. Enterprise users might lean towards Windows for compatibility with Windows’s workstations, but server admins broadly work in Linux. If you want to understand and work with servers, you need to understand Linux. 2…. Read more

How to Use the Linux type Command

Terminal on a Linux laptopFatmawati Achmad Zaenuri/Shutterstock.com

Find out if a command resolves to an alias, a disk file, a shell function, a built-in command, or a reserved word. Use type to discover how your Linux commands are executed and understand your system better.

Do My Bidding

When we open a terminal window and start issuing commands to our Linux computer, we rarely stop to think what software components within the operating system are reacting to our commands and carrying them out for us. We type the command, get the result, and move on with our workload.

Knowing how the commands are carried out gives us a better understanding of the way our Linux or other Unix-like operating system is constructed. Having a peek beneath the hood can make us a more informed driver.

The instructions we issue to the command line are in one of the following categories:

  • Alias: A user (or system) defined command that causes other, usually long-winded or complex, command sequences to take place.
  • Disk file: A binary executable file, such as /usr/bin/top.
  • Shell function: A user (or system) defined function that can be used on the command line or included in scripts.
  • Builtin command: A command that is carried out by the shell itself, such as pwd.
  • Reserved word: A word that is reserved by the shell such as if and elif. They are also called keywords.

The type command tells us which category any of the Linux commands belongs to. Here’s a quick tutorial to understanding the command’s output.

The type Command

Let’s rattle through some quick examples, for each of the command categories.
