Install LAMP server on Ubuntu

All the components of the LAMP server are available to install using the default system repository of Ubuntu. Hence, we can configure the environment without adding an extra repository. However, before moving forward, just run the system update command to ensure the system rebuilds the APT package index cache.

sudo apt update

Install Lamp server

We can install LAMP server components one by one on our Ubuntu system. However, it is a time-consuming process, hence to make it short here we are using a single command. That will not only install the LAMP server but also enable and start all the required services.

sudo apt install lamp-server^ php

The above command will select all the required packages to set up Apache, MySQL, and PHP on your system.

Uninstall the LAMP Server

Well, when it comes to uninstalling the LAMP server completely from your Ubuntu system, we can use the given command:

sudo apt autoremove --purge apache2* mysql-server* php*

How to Convert PNG, JPEG to WebP in Linux?

Webp is an open-source image format in Linux which supports lossless and lossy compression for images on the web.

One of the best practices to optimize the website performance is using compressed images.

This article will cover how to use webp image format for creating compressed and quality images for the website.


The webp package is already available in the official ubuntu repositories. Run the command below to update the Ubuntu repository to the latest index and install webp package.

sudo apt install webp

Converting image to webp format

Using the cwebp tool, an image can be converted into webp format. Run the cwebp command with option -q to define the quality of image and -o to define the output file.

In this example, I have used image file linux.png and linux.jpeg file to convert in webp format. You can choose your image name accordingly.

cwebp -q 60 linux.png -o linux.webp
cwebp -q 60 linux.jpeg -o linux1.webp

Converting webp image to png and jpeg format

In the previous step, we converted jpeg and png images to webp using cwebp utility tool. Now we will use the dwebp tool to convert webp images into png and jpeg format.

Use the dwep command with the option -o to create png and jpeg image format from webp. In the example, image.webp is used for the conversion.

dwep image.webp -o image.png
dwep image.webp -o image.jpeg

How to use Match in PHP 8

In PHP 8, the match expression was introduced as a more concise and powerful alternative to the switch statement. The match expression allows you to perform pattern matching against a value and execute code based on the matched pattern.

Here’s the basic syntax of the match expression:

match ($value) {
    pattern_1 => expression_1,
    pattern_2 => expression_2,
    // more patterns and expressions...
    pattern_n => expression_n,
    default => expression_default

Here’s how it works:

  • The $value is the expression that you want to match against.
  • pattern_1, pattern_2, and pattern_n are the patterns you want to match against the value. These can be literal values, constants, or expressions.
  • expression_1, expression_2, and expression_n are the expressions that will be executed if the corresponding pattern matches.
  • default is an optional keyword that specifies the default case when none of the patterns match. expression_default is the expression executed in the default case.

The match expression evaluates the value and compares it against each pattern in order. If a pattern matches, the corresponding expression is executed, and the match expression completes. If none of the patterns match, the default case (if provided) is executed. If no default case is provided and no pattern matches, a MatchError is thrown.

Here’s an example to illustrate the usage of the match expression:

$result = match ($value) {
    0 => 'Zero',
    1 => 'One',
    2, 3 => 'Two or Three',
    4, 5, 6 => 'Four, Five, or Six',
    default => 'Other'

In this example, the value of $value is matched against different patterns, and the corresponding expressions are executed based on the match. The result is assigned to the variable $result.

The match expression in PHP 8 provides a more expressive and concise way to perform pattern matching, making your code easier to read and maintain.

How to disable window move with alt + left mouse button in XFCE

If you go to the Xfce menu and choose settings > settings manager > window manager tweaks > accessibility, you can select another key instead of alt to move the windows or choose none at all. This should be just what you want.

You can also use xfconf-query to set easy_click to none (or another key) on the command-line:

xfconf-query -c xfwm4 -p /general/easy_click -s none

In some programs, like Photoshop Alt + left mouse key used to modify some data and it is very important to disable window move with alt + left mouse button in XFCE for correct work of programs.

Ventoy – open source tool to create bootable USB drives

Ventoy is an open source tool to create a bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files.
