Rising from the Ashes: How AlmaLinux and Rocky Linux Redefined the Post-CentOS Landscape

When Red Hat announced the abrupt end of traditional CentOS in late 2020, the Linux ecosystem was shaken to its core. Developers, sysadmins, and enterprises that relied on CentOS for years suddenly found themselves scrambling for answers. Out of that disruption, two projects, AlmaLinux and Rocky Linux, emerged to carry forward the legacy of CentOS while forging their own identities. This article dives into how these two distributions established themselves as reliable, enterprise-grade options for developers and organizations alike.

The Fall of CentOS: An Industry Shockwave

For over a decade, CentOS was the backbone of countless servers, from small web hosts to enterprise data centers. It provided a stable, free, and RHEL-compatible platform, perfect for developers and administrators building and maintaining critical infrastructure.

That stability came to an end when Red Hat pivoted CentOS to a rolling-release model, CentOS Stream. Instead of offering a downstream, binary-compatible version of RHEL, Stream became a preview of future RHEL updates. This move caused widespread frustration:

  • Organizations that built production environments around CentOS suddenly faced shortened support lifecycles.

  • Developers who depended on a “set-and-forget” environment now had to deal with the unpredictability of a rolling release.

  • Compliance-driven industries were left in limbo, as running on an unsupported OS could trigger security and regulatory risks.

This disruption created a vacuum, and the Linux community quickly stepped up to fill it.

The Birth of AlmaLinux and Rocky Linux AlmaLinux: Community-Driven, Enterprise-Ready

Shortly after the CentOS announcement, CloudLinux, a company with deep experience in server environments, launched AlmaLinux. The first stable release landed in March 2021. True to its name, “alma” meaning “soul”, the project’s mission was clear: to embody the spirit of CentOS while maintaining community governance. The non-profit AlmaLinux OS Foundation now oversees the project, ensuring it remains free and open for everyone.

Rocky Linux: A Tribute and a Promise

At almost the same time, Gregory Kurtzer, one of the original CentOS founders, unveiled Rocky Linux, named in honor of CentOS co-founder Rocky McGaugh. From the beginning, Rocky positioned itself as a 1:1 binary-compatible rebuild of RHEL, mirroring CentOS’s original mission. Its governance structure, managed by the Rocky Enterprise Software Foundation (RESF), ensures that the project remains rooted in community oversight rather than corporate ownership.

Why GNOME Replaced Eye of GNOME with Loupe as the Default Image Viewer

Linux Journal
1 month 4 weeks ago
by George Whittaker A Shift in GNOME’s Core Applications

For over two decades, Eye of GNOME (often shortened to EOG) was the silent workhorse of the GNOME desktop environment. It wasn’t flashy, but it did exactly what most people expected: double-click a picture, and it opened instantly. Yet, with the arrival of GNOME 45 in late 2023, a new name appeared in the lineup of “core” apps: Loupe. From that moment forward, Loupe became the official default image viewer on GNOME desktops, displacing EOG.

This decision wasn’t made lightly. GNOME has been steadily refreshing its default applications in recent years, Gedit was replaced by GNOME Text Editor, and Cheese gave way to Snapshot. Loupe is the continuation of this modernization trend. Eye of GNOME is still available in repositories for those who want it, but the GNOME team has shifted its endorsement to Loupe as the better long-term solution.

What Loupe Brings to the Table

Loupe isn’t just a reskin of EOG. It was built from scratch with today’s hardware, design standards, and security expectations in mind. At first glance, the interface looks minimal, but there’s more happening beneath the hood than many realize.

  • Rust-Powered Foundation – Unlike Eye of GNOME’s decades-old C codebase, Loupe is written in Rust. This choice immediately grants it memory safety, helping avoid whole categories of crashes and vulnerabilities. For an app that regularly opens untrusted files, this is an important safeguard.

  • GPU-Accelerated Image Handling – Instead of pushing all rendering to the CPU, Loupe leverages the GPU. Panning across a large image or zooming into a 50-megapixel photo feels fluid, even on high-resolution displays.

  • Touch-Friendly Navigation – GNOME has been preparing for a future that includes more touch devices. Loupe fits right in, supporting pinch-to-zoom, two-finger swipes to move between images, and smooth transitions that feel natural on both touchscreens and trackpads.

  • Streamlined Metadata View – Instead of burying photo information behind a separate dialog, Loupe integrates an optional sidebar. With a click, you can see dimensions, file size, EXIF data, and even location details without leaving the main view.

  • Security Through Sandboxing – Image decoding is handled in isolated processes using a new backend called Glycin. If a corrupt or malicious image tries to crash the decoder, it won’t take the entire viewer down with it.

Ptyxis: Ubuntu’s Leap Into GPU-Powered Terminals

Linux Journal
2 months ago
by George Whittaker

For decades, the humble terminal has been one of the most unchanging parts of the Linux desktop. Text streams flow in monochrome grids, and while the underlying libraries have evolved, the experience has remained more or less the same. Ubuntu, however, is preparing to rewrite this narrative. The distribution is adopting Ptyxis, a fresh terminal emulator designed for modern computing, and one of its standout qualities is that it leans on the GPU for rendering rather than relying solely on the CPU.

This shift is more than cosmetic. It represents a rethink of how command-line tools should perform in an era of container-heavy development, high-DPI displays, and demanding workloads. Let’s unpack what makes Ptyxis a different breed of terminal, why Ubuntu is betting on it, and what it means for everyday users and power developers alike.

The Origin Story of Ptyxis

Ptyxis is not an accidental side project. It was initially prototyped under the name GNOME Prompt by Christian Hergert, a well-known GNOME contributor also behind GNOME Builder. Early experiments showed there was space for a terminal designed from scratch with today’s GNOME ecosystem and GPU pipelines in mind.

To avoid conflicts with existing software, the project was later rebranded as Ptyxis. The application has since matured rapidly, and major distributions such as Fedora and Ubuntu have committed to it. Ubuntu introduced it in experimental form in 24.10, and by the upcoming Ubuntu 25.10 “Questing Quokka”, it is expected to replace the aging GNOME Terminal as the default choice.

A New Kind of Terminal Experience GPU Acceleration as the Core

Traditional terminals typically rely on CPU-bound rendering stacks, often through libraries like Cairo and Pango. This works fine until you throw thousands of lines of log output or try to run full-screen text-based UIs that push rendering to its limits. Ptyxis sidesteps these bottlenecks by shifting the drawing work to the graphics processor, taking advantage of Vulkan or OpenGL backends supplied by GTK4.

The result is immediately noticeable: smooth scrolling, responsive updates, and consistent performance even with massive amounts of text on screen. It’s not just about speed, either, offloading rendering to the GPU reduces CPU strain, leaving headroom for the processes you’re actually running.
