Cisco Updates Networking Products in Bid To Tap AI-Fueled Demand

3 weeks 6 days ago
Cisco is updating its networking and security products to make AI networks speedier and more secure, part of a broader push to capitalize on the AI spending boom. From a report: A new generation of switches -- networking equipment that links computer systems -- will offer a 10-fold improvement in performance, the company said on Tuesday. That will help prevent AI applications from suffering bottlenecks when transferring data, Cisco said. Networking speed has become a bigger issue as data center operators try to manage a flood of AI information -- both in the cloud and within the companies' own facilities. Slowdowns can hinder AI models, Cisco President and Chief Product Officer Jeetu Patel said in an interview. That applies to the development phase -- known as training -- and the operation of the models, a stage called inference. A massive build-out of data centers has made Cisco more relevant, he said. "AI is going to be network-bound, both on training and inference," Patel said. Having computer processors sit idle during training because of slow networks is "just throwing away money."

Fedora 41’s Immutable Future: The Rise of Fedora Atomic Desktops

3 weeks 6 days ago
by George Whittaker

The Fedora Project has long stood at the forefront of Linux innovation, often acting as a proving ground for transformative technologies later adopted by the wider Linux ecosystem. With the release of Fedora 41, the project takes another major leap into the future by fully embracing immutable desktops through its newly unified and rebranded initiative: Fedora Atomic.

This bold shift represents more than a technical update — it signals a philosophical evolution in how Linux desktops are built, managed, and secured. Fedora Atomic is not just a feature of Fedora 41; it's the flagship identity for a new kind of Linux desktop. In this article, we explore the origins, architecture, benefits, and implications of Fedora Atomic as it makes its debut in Fedora 41.

What Are Immutable Desktops? A Paradigm Shift in OS Architecture

An immutable desktop is a system whose core filesystem is read-only, meaning the foundational components of the operating system cannot be altered during regular use. This design flips traditional Linux system management on its head.

In mutable systems — like the standard Fedora Workstation or most desktop Linux distributions — the root filesystem is writable, allowing users or software to modify system libraries, configurations, and services at will. While this provides flexibility, it introduces risks of accidental misconfiguration, malware persistence, or system instability.

Immutable desktops tackle these issues with several key principles:

  • Read-Only Root Filesystem: Ensures the core system is consistent and protected.

  • Atomic Updates: System updates are applied as a whole, transactional unit. If something breaks, you can simply roll back to the previous working version.

  • Separation of Concerns: Applications are isolated in containers (e.g., Flatpaks), and development environments run in dedicated containers (e.g., Toolbox).

  • Reproducibility and Consistency: Identical environments across systems, ideal for testing and deployment pipelines.

Fedora Atomic is the embodiment of these principles — and Fedora 41 is the foundation upon which it stands.

From Silverblue to Atomic: The Evolution of Fedora's Immutable Desktop Vision

Fedora Atomic is not built from scratch. It is the evolution of Fedora Silverblue, Kinoite, and Sericea, which previously offered immutable desktop environments with GNOME, KDE Plasma, and Sway respectively. In Fedora 41, these projects are now rebranded and unified under the Fedora Atomic name, creating a streamlined identity and experience for users.
