What is a tar.gz File, and How Do I Open It?

A tar file, often called a tarball, is a collection of files wrapped up in one single file for easy storage. Rather than keep track of a whole folder of files, you only need to keep track of one. Tar files are often compressed after being created, giving it the .tar.gz file extension. Technically these are TGZ files, but nearly everyone calls both .tar and .tar.gz files simple “tar files.”

How To Take Back A Friend Request On Facebook

You can send a friend request to other people on Facebook. It is up to other person to accept it and sometimes, they just let friend requests sit. This means your request is still pending; it’s there and it’s not going to be accepted. In such cases, you have the option to take back a friend request. You might have decided that you’re tired of waiting for your ‘friend’ to accept the request, and you’d like to rescind the invitation.

Take Back A Friend Request

Visit Facebook on your desktop browser. Click the Friend request button at the top right, and in the menu that open, click ‘See all’ at the bottom. This will take you to a list of all your pending friend requests. There’s an option on this page called ‘View sent requests’. Click it.

You will see all the people you’ve sent a friend request to. Hover the mouse over the ‘Friend Request Sent’ button and a menu will open. In the menu, click the ‘Cancel Request’ option.

On the Facebook apps, and go to the hamburger tab i.e., the one with the three lines icon. Scroll down and tap Friends. The Friends screen has tabs of its own. Go to the Outgoing tab. The Outgoing tab will list all the people you’ve sent friend requests to. Tap the ‘undo’ button under a request to take it back.

The person you sent the friend request to won’t know you took it back unless they compulsively check their pending friend requests to see who’s on it, and they notice one request is gone. If you send them a request again, they will be notified of the new request which means they will be able to work out what happened with the original request if they remember that you sent it before.

We should warn you not to abuse the feature. It’s fine to want to take a friend request back if it’s been sitting too long but to use the feature to repeatedly remind someone they have a friend request from you isn’t a good idea and probably borders on crazy. It might even be illegal in some countries but that’s just a guess. If you keep revoking and re-sending a friend request, it’s possible the person you send the request to will report you to Facebook or Facebook will take notice and maybe ban your account.

On that same note, if you’re tired of getting friend requests from someone, just block them.

How To Fix Missing Hibernation Option On Windows 10

Windows 10 lets you put your system to sleep, or hibernate it. Older versions of Windows had these same two options. You can choose to hide both the Sleep and Hibernate option on the power button menu from the Power Plan settings on Windows 10. That said, if you don’t see the hibernate option in the Power Plan settings, it may be because Hibernate is disabled. When hibernate is disabled, the option is removed from the UI completely. It doesn’t appear as a greyed out option. Instead, it just looks as though it doesn’t exist. Here’s how you can fix the missing hibernation option on Windows 10.

Fix Missing Hibernation Option

You can enable hibernation with a command prompt command. You will need administrative rights to enable it. Open Command Prompt with administrative rights. Run the following command. It won’t return anything but it takes only a split second to run and hibernation will be enabled.

powercfg -h on

After you enable hibernation, open the Power Plan options. Right-click the battery icon and select Power Options. Alternatively, open File Explorer and paste the following in the location bar.

Control Panel\Hardware and Sound\Power Options

Click the Choose what the power buttons do option on the left. Click the Change settings that are currently unavailable option. Enable the Hibernate option and it will start appearing in the Power button menu in the Start Menu.

Memory Usage

If you use Hibernate mode, it will take up space on your hard drive. Hibernation works by saving the current state of your system to the hard drive. Normally, this doesn’t add up to more than a few GBs of disk space however it can grow substantially large over time. To fix this, you can turn Hibernate off, and the file will be deleted. You can turn it on right after and continue to use the mode.

If you’re short on disk space as it is, you can use a command prompt command to set the hibernation file size. By default it’s set between 70% – 75%. The following command lets you change it to a different percentage. The percentage is that of your RAM and it cannot be set to less than 50%. You can grow it to 100% if you want, or reduce it to as low as 50% but nothing less than that. If it’s still taking up too much space on your system, consider using the Sleep mode, or shutting down your system instead.

Powercfg –h –size percentsize

Example

Powercfg –h –size 55%

How To Create Application Menu Shortcuts On Linux

Users start programs on Linux with “launchers”. These files contain specific instructions for how the Linux operating system should run the program and how the icon should look, among other things. On Linux, if you want to create application menu shortcuts, you’ll find that it’s a bit more difficult, compared to Mac or Windows, as users can’t just right-click on a program and select the “create shortcut” option. Instead, if you’d like to create application menu shortcuts on the Linux desktop, it’s an involved process that takes a bit of know-how.

Application Menu Shortcuts – Terminal

Perhaps the quickest way to create application menu shortcuts on the Linux desktop is to create one in the terminal. Going the terminal route is less user-friendly, as there’ isn’t a nice GUI editor to assign app categories, and no icon chooser, etc.

The first step to creating a new application shortcut in Linux is to create an empty Desktop file. In the terminal, use the touch command to create a new shortcut.

touch ~/Desktop/example.desktop
chmod +x ~/Desktop/example.desktop

The new shortcut icon is on the desktop, but it has no program instructions. Let’s fix this by editing the new file in the Nano text editor.

nano ~/Desktop/example.desktop

The first line for any application shortcut is “Name”. This line will give the application shortcut its name in the menus. In Nano text editor, give your shortcut a name.

Name=Example Shortcut

Following “Name,” the next line in the shortcut to add is “Comment.” This line is optional but very useful as it allows the menu to display some information about the shortcut.

Comment=This is an example launcher

With “Name” and “Comment” out of the way, we can get to the real meat of the launcher. In the Nano text editor, add the “Exec” line.

The “Exec” line tells your Linux OS where the program is, and how it should start.

Exec=command arguments

Exec is very versatile and can launch Python, Bash, and just about anything else you can think of. For example, to run a shell or bash script via the shortcut, do:

Exec= sh /path/to/sh/script.sh

Alternatively, set your app shortcut to run a Python program with:

Exec=python /path/to/python/app

Once the “Exec” line is set to your liking, add the “Type” line.

Type=Application

Need to set your custom shortcut up with an icon? Use the “Icon” line.

Icon=/path/to/custom/icon

Now that Name, Comment, Exec, and Icon are set, it’s safe to save the custom shortcut. Using the Ctrl + O keyboard combination, save the app shortcut. Then, exit Nano with Ctrl + X.

Install your custom app shortcut system-wide with:

sudo mv ~/Desktop/example.desktop /usr/share/applications

Application Menu Shortcuts – Alacarte

There are many menu editors on Linux. For the most part, they all work similarly and do the same thing. For best results, we recommend using the Alacarte app. It’s easy to use, works on everything and can be installed on even the most obscure Linux distributions (due to it’s relationship to the Gnome project).

Alacarte may already be installed on your Linux PC. Check and see by pressing Alt + F2, typing “alacarte” and clicking enter. If the app launches, you’ve already got it installed. If nothing happens, you’ll need to install it. Follow the instructions below to get it working.

Ubuntu

sudo apt install alacarte

Debian

sudo apt-get install alacarte

Arch Linux

sudo pacman -S alacarte

Fedora

sudo dnf install alacarte -y

OpenSUSE

sudo zypper install alacarte

Generic Linux

Not able to find the Alacarte menu editor app on your Linux distribution? Visit the souce code site and build it yourself!

Make Shortcuts

Making shortcuts with the Alacarte menu editor is refreshingly simple. To start off, click on a category. In this example, we’ll make a new shortcut in the “Internet” category.

In the “Internet” category, click the “New Item” button. Selecting the “New Item” option will open up “Launcher Properties”.

In the “Launcher Properties” windows, there are a few things to fill out. The first thing to fill out is “Name”. Write in the name of the launcher in the “Name” section. Then, move on to “Command.”

The “Command” section is where the user specifies what the shortcut will do. Click the “browse” button to search for a shell script, binary, python app, etc and load it in. Alternatively, write in a command, like one of the following:

python /path/to/python/app.py

or

sh /path/to/shell/script/app.sh

or

wine /path/to/wine/app.exe

When the launcher’s “Command” section is set, write a comment in the “Comment” section and then select “OK” to finish. After clicking the “OK” button, Alacarte will instantly save and enable your new app shortcut on the Linux desktop!
