Version control is a fundamental tool in modern software development, enabling teams and individuals to track, manage, and collaborate on projects with confidence. Whether you're working on a simple script or a large-scale application, keeping track of changes, collaborating with others, and rolling back to previous versions are essential aspects of development. Among various version control systems, Git has emerged as the most widely used and trusted tool — especially on Linux, where it integrates seamlessly with the system's workflow.

This guide will walk you through the basics of Git on Linux, explaining what Git is, how to install it, and how to start using it to manage your projects efficiently. Whether you're a new developer or transitioning from another system, this comprehensive introduction will help you get started with Git the right way.

What Is Git and Why Use It?

Git is a distributed version control system (DVCS) originally created by Linus Torvalds in 2005 to support the development of the Linux kernel. It allows developers to keep track of every change made to their source code, collaborate with other developers, and manage different versions of their projects over time.

Key Features of Git:

• Distributed Architecture: Every user has a full copy of the repository, including its history. This means you can work offline and still have full version control capabilities.

• Speed and Efficiency: Git is optimized for performance, handling large repositories and files with ease.

• Branching and Merging: Git makes it easy to create and manage branches, allowing for efficient parallel development and experimentation.

• Integrity and Security: Every change is checksummed and stored securely using SHA-1 hashing, ensuring that your project’s history cannot be tampered with.

Compared to older systems like Subversion (SVN) or CVS, Git offers far greater flexibility and is better suited to both small personal projects and large collaborative efforts.

Installing Git on Linux

Installing Git on Linux is straightforward thanks to package managers available in every major distribution.

For Ubuntu/Debian-based Systems:

sudo apt update sudo apt install git

For Fedora:

sudo dnf install git

For Arch Linux:

sudo pacman -S git

After installation, verify it with:

git --version

A new version of DeaDBeeF music player is out with some cool features, FFMPEG 7 support, and a flurry of bug fixes sure to appease long-time fans of this tool. Admittedly, the popularity of traditional desktop music player apps like this one has dipped considerably since the arrival of music streaming services like Spotify. They give on-demand (and often free) access to expansive music catalogues. Still, many people (myself included) continue to maintain music libraries filled with MP3s etc. I’d wager most such users have (by now) settled on a preferred music client; for many, that choice is DeaDBeeF.

In the world of Linux, where multi-user systems and server security are foundational principles, understanding file permissions and ownership is crucial. Whether you're a beginner exploring your first Linux distribution or a seasoned system administrator managing critical servers, knowing how permissions work is key to ensuring the integrity, privacy, and functionality of your system.

This guide will take you deep into the core of Linux file permissions and ownership—what they are, how they work, how to modify them, and why they matter.

Why File Permissions and Ownership Matter in Linux

Linux is built from the ground up as a multi-user operating system. This means:

• Multiple users can operate on the same system simultaneously.

• Different users have different levels of access and control.

Without a permissions system, there would be no way to protect files from unauthorized access, modification, or deletion. File permissions and ownership form the first layer of defense against accidental or malicious activity.

Linux Permission Basics: Read, Write, Execute

Each file and directory in Linux has three basic types of permissions:

• Read (r) – Permission to view the contents of a file or list the contents of a directory.

• Write (w) – Permission to modify a file or create, rename, or delete files within a directory.

• Execute (x) – For files, allows execution as a program or script. For directories, allows entering the directory (cd).

Permission Categories: User, Group, Others

Permissions are assigned to three distinct sets of users:

• User (u) – The file's owner.

• Group (g) – A group associated with the file.

• Others (o) – Everyone else.

So for every file or directory, Linux evaluates nine permission bits, forming three sets of rwx, like so:

rwxr-xr--

This breakdown means:

• rwx for the owner

• r-x for the group

• r-- for others

Understanding the Permission String

When you list files with ls -l, you’ll see something like this:

-rwxr-xr-- 1 alice developers 4096 Apr 4 14:00 script.sh

Will Ubuntu 25.10 be codenamed the Quizzical Quokka? It’s an adjective + animal moniker Canonical’s marketing team tersely tweeted today—sans context—but as today is April 1 (aka April’s Fools Day, aka the day when companies, teams, and unpaid marketing interns spam the web with try-hard lolslop)… I’m questioning it. Ubuntu 25.10 could well be a Quizzical Quokka, but it also may not be — and if it isn’t, should it? The ‘Quizzical’ element is a playful if slightly odd adjective to roll with.

In Linux, groups play a central role in managing user permissions and access control. Whether you're an experienced system administrator or a curious new user, understanding how to list and analyze group information is a fundamental skill. This guide explores everything you need to know about listing groups in Linux, using a variety of tools and techniques to get exactly the information you need.

What Are Groups in Linux and Why Do They Matter?

Linux is a multi-user operating system, and one of its strengths lies in the fine-grained control it offers over who can do what. Groups are a way to organize users so that multiple people can share access to files, devices, or system privileges.

Each group has:

• A group name

• A Group ID (GID)

• A list of users who are members of the group

Types of Groups:

• Primary group: Each user has one primary group defined in /etc/passwd. Files the user creates are associated with this group by default.

• Secondary (or supplementary) groups: Users can belong to additional groups, which allow access to other resources.

How to List All Groups on a Linux System

To see every group that exists on the system, you can use the following methods:

getent group

getent group

This is the preferred method on modern systems because it queries the system’s name service switch configuration (NSS). It includes local and possibly remote group sources (like LDAP or NIS).

Example output:

sudo:x:27: docker:x:999:user1,user2 developers:x:1001:user3

cat /etc/group

cat /etc/group

This command prints the content of the /etc/group file, which is the local group database. It’s simple and fast, but it only shows local groups.

Each line is formatted as:

group_name:password_placeholder:GID:user1,user2,...

compgen -g (Bash built-in)

compgen -g

This command outputs only the group names, which is helpful for scripting or cleaner views.

How to List Groups for a Specific User

You might want to know which groups a particular user belongs to. Here’s how:

groups username

groups john

Outputs a space-separated list of groups that john belongs to. If no username is given, it shows groups for the current user.

id username

id alice

A new initiative, called "EU OS," has been launched to develop a Linux-based operating system tailored specifically for the public sector organizations of the European Union (EU). This community-driven project aims to address the EU's unique needs and challenges, focusing on fostering digital sovereignty, reducing dependency on external vendors, and building a secure, self-sufficient digital ecosystem.

What Is EU OS?

EU OS is not an entirely novel operating system. Instead, it builds upon a Linux foundation derived from Fedora, with the KDE Plasma desktop environment. It draws inspiration from previous efforts such as France's GendBuntu and Munich's LiMux, which aimed to provide Linux-based systems for public sector use. The goal remains the same: to create a standardized Linux distribution that can be adapted to different regional, national, and sector-specific needs within the EU.

Rather than reinventing the wheel, EU OS focuses on standardization, offering a solid Linux foundation that can be customized according to the unique requirements of various organizations. This approach makes EU OS a practical choice for the public sector, ensuring broad compatibility and ease of implementation across diverse environments.

The Vision Behind EU OS

The guiding principle of EU OS is the concept of "public money – public code," ensuring that taxpayer money is used transparently and effectively. By adopting an open-source model, EU OS eliminates licensing fees, which not only lowers costs but also reduces the dependency on a select group of software vendors. This provides the EU’s public sector organizations with greater flexibility and control over their IT infrastructure, free from the constraints of vendor lock-in.

Additionally, EU OS offers flexibility in terms of software migration and hardware upgrades. Organizations can adapt to new technologies and manage their IT evolution at a manageable cost, both in terms of finances and time.

However, there are some concerns about the choice of Fedora as the base for EU OS. While Fedora is a solid and reliable distribution, it is backed by the United States-based Red Hat. Some argue that using European-backed projects such as openSUSE or KDE's upcoming distribution might have aligned better with the EU's goal of strengthening digital sovereignty.

Conclusion

EU OS marks a significant step towards Europe's digital independence by providing a robust, standardized Linux distribution for the public sector. By reducing reliance on proprietary software and vendors, it paves the way for a more flexible, cost-effective, and secure digital ecosystem. While the choice of Fedora as the base for the project has raised some questions, the overall vision of EU OS offers a promising future for Europe's public sector in the digital age.

Linus Torvalds Acknowledges Missed Release of Linux 6.14 Due to Oversight

Linux kernel lead developer Linus Torvalds has admitted to forgetting to release version 6.14, attributing the oversight to his own lapse in memory. Torvalds is known for releasing new Linux kernel candidates and final versions on Sunday afternoons, typically accompanied by a post detailing the release. If he is unavailable due to travel or other commitments, he usually informs the community ahead of time, so users don’t worry if there’s a delay.

In his post on March 16, Torvalds gave no indication that the release might be delayed, instead stating, “I expect to release the final 6.14 next weekend unless something very surprising happens.” However, Sunday, March 23rd passed without any announcement.

On March 24th, Torvalds wrote in a follow-up message, “I’d love to have some good excuse for why I didn’t do the 6.14 release yesterday on my regular Sunday afternoon schedule,” adding, “But no. It’s just pure incompetence.” He further explained that while he had been clearing up unrelated tasks, he simply forgot to finalize the release. “D'oh,” he joked.

Despite this minor delay, Torvalds’ track record of successfully managing the Linux kernel’s development process over the years remains strong. A single day’s delay is not critical, especially since most Linux users don't urgently need the very latest version.

The new 6.14 release introduces several important features, including enhanced support for writing drivers in Rust—an ongoing topic of discussion among developers—support for Qualcomm’s Snapdragon 8 Elite mobile chip, a fix for the GhostWrite vulnerability in certain RISC-V processors from Alibaba’s T-Head Semiconductor, and a completed NTSYNC driver update that improves the WINE emulator’s ability to run Windows applications, particularly games, on Linux.

Although the 6.14 release went smoothly aside from the delay, Torvalds expressed that version 6.15 may present more challenges due to the volume of pending pull requests. “Judging by my pending pile of pull requests, 6.15 will be much busier,” he noted.
