GParted is a graphical dynamic partition management tool for Linux. In other words, it does useful things like non-destructively expand or shrink disk partitions while they contain data. It's not unfair to describe it as a FOSS recreation of the late lamented PartitionMagic.

Python is one of the most ubiquitous development languages; it's used frequently by sysadmins, data scientists, back-end software developers, and web developers. Python has many use cases, and this tutorial explores how to use it for scripting common sysadmin tasks.

For some reasons, the Chromium browser is occasionally affected by an annoying graphical glitch which occurs mostly when watching YouTube videos. Let's see some solutions to fix this problem.

With the evolution of technology, we find ourselves needing to be even more vigilant with our online security every day. Our browsing and shopping behaviors are also being continuously tracked online via tracking cookies being dropped on our browsers that we allow by clicking the “I Accept” button next to deliberately long agreements on websites before we can get the full benefit of said site.

When you're a technologist, and you hear "containers" and "supply-chain," your mind immediately turns to Docker containers and supply-chain software. Most people, however, think of container ships and the physical supply chain that brings milk and bread to their local grocery store. However, these two concepts have more in common than you might think. A. P. Møller - Mærsk A/S (Maersk) is a leading global container logistics and shipping services leader company that uses open-source software to deliver its goods.

When you run the lsblk -l or df -h command to list out the available block/storage devices, you may find the /dev/loop filesystem, especially if you are using the Snap package manager, and it’s quite common to find in Ubuntu distributions. If you are keen on knowing what loop devices are and how to mount and unmount them from the system, then this article will be enough for you because it will cover all the necessary aspects of loop devices, like how to create a loop device, loop filesystem, mounting, and unmounting steps.

There are so many open source backup software out there, each with different features. But ever thought that you don’t want these complicated and fully-fledged solutions? Try Duplicati for simplicity.

Amazon Simple Storage Service (S3) is a web service offered by Amazon Web Services (AWS) for storing and access to objects via the internet. S3 offers websites, web services, and mobile applications the ability to upload data and store it on its servers. In this guide, we will create and configure a simple static website using Amazon S3.

AlmaLinux vs Rocky Linux! Undoubtedly, they are the two most popular RHEL forks, but which one is the right choice? In this article, I’ll share my thoughts on the matter.

The first part of this series appeared back in 2018. It describes how you can use gnuplot to build a simplified GIS. I wasn't intending to do any more with this idea, but I was tinkering with animated map GIFs and realised that the gnuplot approach had some advantages.

Netdata is a free, open-source and real-time server monitoring tool that visualize and monitor real-time data like CPU usage, RAM usage, Load, SWAP usage, Bandwidth usage, Disk usage, etc. In this tutorial, we will show you how to install the Netdata monitoring tool on Alma Linux 8.

Arm says heterogeneous compute architectures – those with a mix of CPUs, GPUs, DPUs, and other processor types – pose a challenge for software developers, and greater multi-architecture support is needed to address this.

Ryan Finnie announced today the release of Finnix 124 as the newest stable version of his Debian-based live Linux distro targeting casual system administrators with hundreds of utilities for system recovery, maintenance, testing, and more.

Rolling Rhino is a new community remix of Ubuntu, but with a unique twist: it has a whole new release model, rather than just a different desktop. The new remix builds upon a tool of the same name. The Rolling Rhino script converts an installation of one of Ubuntu's daily images into a rolling release by setting it to track the devel branch of the distro. The Rolling Rhino remix simplifies this process somewhat by allowing you to install the distro already configured in the relevant way.

The Fedora Project announces the immediate availability of Fedora Linux 36 Beta, the next step towards our planned release at the end of April.

If you speak to people running Kubernetes in production, one of the complaints you'll often hear is how difficult multitenancy is. Organizations use two main models to share Kubernetes clusters with multiple tenants, but both present issues.

For the second summer, Major League Hacking (MLH) is running the Production Engineering Track of the MLH Fellowship, powered by Meta. This 12-week educational program is 100% remote and uses industry-leading curriculum from Linux Foundation Training & Certification. The program is hands-on, project-based, and teaches students how to become Production Engineers. The goal of the program is for all participants to land a job or internship in the Site Reliability Engineering space, and it will be opened to 100 active college students who meet our admissions criteria.

In this tutorial, we are going to explain the “du” command used on every Linux distribution such as Ubuntu, Debian, or CentOS.

“Du” stands for Disk Usage and every Linux user should use it very often to check the amount of disk space used by directory or file. Using the “du” command is very simple by typing it on the console and adding additional phrases called options. In other words, the “du” command is different every time, according to the needs of the user and what the user wants to be displayed as output.

Many technology firms are turning to open source tools to accelerate innovation and growth. As these firms work to influence open source projects, governance practices sometimes shift from coordination among a small group of developers and firms to management by large communities of contributors and organizations, often with competing priorities.
