How to Shorten the cwebp Command in Linux Mint with a Bash Function

Posted on August 20, 2026Last updated on August 20, 2026 by Shah Alom

I usually optimize images locally before uploading them to the live servers for my websites. Since I use Linux Mint, one of my regular tools for this job is cwebp, which I run directly from the command line to convert PNG and JPG images to WebP.

My most-used command is simple:

cwebp image-name.png -o image-name.webp

It works well, but after using it again and again, I started looking for a way to avoid typing the same filename twice every time I converted an image. When filenames are long, that small repetition becomes even more annoying.

Because I already use the Linux terminal for this task, I wanted a solution that would stay simple and keep using cwebp rather than adding another application. I solved it by creating a small Bash function called towebp.

Arkansas Facts: Capital, Major Cities, Geography & Economy

Posted on August 20, 2026Last updated on August 20, 2026 by Suma Akter

Arkansas is a state where mountain country, broad river valleys, forests, farmland, and fast-growing cities all meet. Located in the south-central United States, it stretches from the Ozark and Ouachita mountains to the flat, fertile lands along the Mississippi River. Little Rock is both the state capital and its largest city, while Northwest Arkansas has become one of the state’s busiest centers for population growth, education, retail, food production, and transportation.

Arkansas is also deeply tied to American history. It entered the Union in 1836, played an important role in the Civil War, and later became the setting for one of the defining school-desegregation struggles of the Civil Rights Movement. Today, the state’s economy mixes agriculture and manufacturing with retail, logistics, healthcare, tourism, and other services.

This guide covers the most useful Arkansas facts, including its capital, major cities, geography, population, economy, GDP, history, landmarks, state symbols, and facts students are likely to encounter in school or general-knowledge quizzes.

How to Install and Uninstall Software on Linux Mint and Debian-Based Linux

Posted on July 16, 2026Last updated on August 5, 2026 by Shah Alom

Installing software on Linux Mint, Ubuntu, Debian, and other Debian-based Linux distributions is usually simple. However, Linux applications are distributed in several formats, including APT packages, .deb files, Flatpaks, Snaps, AppImages, compressed archives, and source code.

Each format uses a different installation and removal method. For example, an AppImage is normally removed by deleting its file, while an application installed through APT should be removed with an APT command.

This guide explains how to safely install, update, identify, troubleshoot, and uninstall software on Linux Mint and other Debian-based operating systems. It is written for beginners but also includes useful commands for experienced Linux users.

Important Corrections to Common Linux Commands

Before starting, it is important to correct a few common misunderstandings about Linux software installation.

A .tar.gz file is a compressed archive. It is not a Snap package.
An AppImage is normally a portable executable file. It is not managed by apt or dpkg.
To remove an AppImage, you normally delete the AppImage file and any optional shortcuts or settings it created.
For a local .deb package, sudo apt install ./package.deb is usually better than sudo dpkg -i package.deb because APT can resolve dependencies.
You normally do not need sudo to make an AppImage executable.
apt purge removes package-managed configuration files, but it does not normally remove all personal settings from your home directory.

The Center of the Universe: Tulsa’s Echoing Enigma

Posted on December 20, 2024Last updated on December 20, 2024 by MD. Sadikul Islam

In the heart of Tulsa, Oklahoma, lies a curious acoustic phenomenon called the Center of the Universe. Located on the Boston Avenue Pedestrian Bridge, this seemingly ordinary circular platform, surrounded by a ring of bricks, boasts an extraordinary property: it amplifies and distorts sound.

Standing within the circle’s center, a person’s voice echoes back with surprising intensity, creating a unique and almost private auditory experience. This effect is largely imperceptible to those outside the circle, adding an element of intrigue.

What is the difference between Gorge and Canyon?

Posted on October 24, 2024Last updated on August 16, 2026 by MCQ Academy

The terms “gorge” and “canyon” both refer to deep valleys with steep sides, often formed by the erosion caused by rivers over time. However, there are a few distinctions between them, particularly in terms of size and geological characteristics:

Definitional difference between gorge and canyon:

A gorge is typically a narrow, steep-sided valley that is often smaller and more confined. Gorges are usually formed by rivers cutting through hard rock, creating steep walls on either side. Often used to describe smaller, more dramatic and steep-sided valleys.
A canyon is a much larger, wider, and deeper valley with steep cliffs on both sides, often formed over a long period by the erosion caused by rivers. Canyons are typically broader in scale compared to gorges. Used for larger-scale valleys that are wide and deep.
