Grumpy old sysadmin, #Linux, #OpenSource. #privacy & #security fanatic.

Happily running Linux as my daily driver since 1992.

Happily rocking my fedora at #RedHat since 2013.

Very, very married....

Now generally available: Red Hat Confirmed Sovereign Support drives digital autonomy for global enterprise

Learn about Red Hat Confirmed Sovereign Support, a premium, in-region operational service that helps protect critical workloads from violating jurisdictional boundaries. Discover how it maintains reliability in support engineering while enforcing data and operational sovereignty.

Managing #RHEL on Google Cloud just got more intuitive—and secure. 🐧

The new Red Hat Lightspeed Agent uses secure Agent-to-Agent (A2A) protocol to connect with Google’s Gemini. This lets SREs use natural language for infra tasks while keeping data in enterprise boundaries.

It’s a pragmatic way to scale expertise without the usual privacy trade-offs.

Unlock enterprise-ready, secure AI with Red Hat Lightspeed Agent for Google Cloud

The Red Hat Lightspeed Agent for Google Cloud is an enterprise-ready tool designed specifically for Red Hat Enterprise Linux (RHEL) to help Site Reliability Engineers (SREs) and IT administrators manage their Red Hat infrastructure on Google Cloud using natural language.

Managing Disconnected RHEL Environments

High-security or restricted environments require a specialized approach to content delivery. This resource outlines the methodology for managing disconnected environments, focusing on operational consistency when external connectivity is not an option.

Key Points:

Enablement: Architecting offline delivery.

Security: Hardened posture for air-gapped sites.

As an early user of Enlightenment, an OpenSource advocate and old man who is thrilled to see the accomplishments fo our next generation this story really made my day brighter.

Congratualtions Kamila Szewczyk!

Merging DRBD-9.3 into the Linux Upstream

Sounds like exciting times at LINBIT as their multi-peer code makes it's way into the upstream #Linux kernel.

Merging DRBD-9.3 into the Linux Upstream

We are currently working on merging DRBD-9.3 into the Linux upstream. But how did we get here? DRBD-8.4 works only with a single peer; it is a software for two-node failover clusters. And the DRBD that comes with the upstream Linux is equivalent to drbd-8.4. The most recent release was 8.4.11, eight years ago. However, […]

NEW, by me: Sweden has blamed Russian government-linked hackers for attempting a destructive cyber attack on a thermal plant in western Sweden in 2025.

The cyberattack failed, but it's the latest in a string of Russia-linked incidents targeting critical infrastructure in Europe in recent years.

Sweden blames Russian hackers for attempting 'destructive' cyberattack on thermal plant | TechCrunch

Sweden's minister for civil defense said Russian hackers are "now attempting destructive cyber attacks against organizations in Europe."

The EU has announced the EURO-3C, a cloud service to keep “sovereign data” in European servers. But 70 percent of EU cloud services are currently using US company services. Who can step in to fill the gap? https://spectrum.ieee.org/europe-cloud-sovereignty?utm_source=mastodon&utm_medium=social&utm_campaign=fedica-Mastodon-Daily-Pipeline
Is EURO-3C Europe's Path to Cloud Sovereignty?

How will the EU's new cloud framework impact the dominance of US tech giants in Europe?

In the enterprise, "stability" isn't a buzzword—it's a requirement. Red Hat just moved the needle with RHEL Extended Life Cycle, Premium. 🐧

We’re talking a 14-year lifecycle and 6 years of extended maintenance for minor releases in one subscription. This is about providing "well-lit paths" for mission-critical systems, allowing you to manage tech debt on your timeline, not a vendor's.

Red Hat Enhances Enterprise Stability with Red Hat Enterprise Linux Extended Life Cycle, Premium

Red Hat Enterprise Linux Extended Life Cycle, Premium, is a new subscription providing a predictable 14-year life cycle for major Red Hat Enterprise Linux releases. The stand-alone subscription consolidates extended support, simplifying the complexity of managing multiple support streams.

Global instant payments are scaling, but fragmented infra and legacy tech debt keep the real value out of reach. 🐧

To achieve true cross-border efficiency, we must solve the interoperability puzzle. Standards like #ISO20022 are "well-lit paths" to unlocking value and AI. The future depends on resilient, flexible platforms that bridge the gap between legacy and modern rails.

AI at the edge is an infrastructure puzzle. Red Hat is helping solve it by contributing llm-d to the #CNCF, establishing "well-lit paths" for AI-RAN orchestration with SoftBank. 🐧

This is about optimization—making inference a first-class citizen alongside traditional containers.

Proud to see Red Hat continuing our legacy of open-source leadership, from #Kubernetes and #etcd to #KEDA and now #llmd.
