Canonical announces live kernel patching for Arm64

Canonical Livepatch now officially supports Arm64, further expanding its security patching automation capabilities. For the first time, Ubuntu on an Arm64 machine can apply critical kernel updates, without service interruption or rebooting. Starting with Ubuntu Core 26 for Arm64, and for Ubuntu Core 20 and onwards for AMD64 machines, a wider range of devices and cloud virtual machines can achieve timely vulnerability remediation through Canonical Livepatch.

Five things your logs will never tell you

A customer escalation hit my queue when I was on the customer smoke jumpers team at an observability vendor. My team was the group that parachutes into Fortune 500 accounts one bad week from churning and usually after a big customer outage. The customer had filed a billing dispute three weeks earlier and their on-call engineers were stuck. They had our full stack: logs, metrics, traces, end-to-end instrumentation, every product we sold and some we didn't. They could see the request came in. They could see it returned a 500. They could not see the body. The trace was sampled out. The log line was truncated at 4KB.

From firefighting to forward planning: a practical route to operational innovation

Operational innovation is often treated as a back-office efficiency exercise, but in practice, it is becoming a strategic discipline. As AI moves deeper into day-to-day operations, technical leaders need a clearer way to cut toil, reduce risk and build the capacity to innovate. For many operations teams, it starts with incident management. When responders are trapped in noisy alert streams, manual escalations and fragmented workflows, innovation is pushed aside by the urgent work of keeping services available.

Who's in Charge? The 4 Key Pillars of AI Governance in 2026

You hire an astute, hard-working, fresh graduate to run things for you. You hand them the keys to everything in your company; that includes every system, every endpoint, every file, and every password, all of it. Your only instruction to them? "Go ahead and improve things!" Then, trusting in their competence, you leave them to it. Doesn't that sound like a recipe for disaster? Yet that's precisely what's happening in IT departments across the world.

How network change management could've prevented a costly switch misconfiguration

Unplanned outages often trace back to a simple but overlooked cause: an untracked configuration change. In many organizations, network device configurations are updated manually without approvals, documentation, or rollback plans. This lack of structure can lead to performance issues, downtime, and compliance risks. In this blog, we'll see how a core switch misconfiguration exposed the risks of unmanaged changes.

Who's Driving Your Data? How to Regain Control of Your Apache Kafka Infrastructure

Apache Kafka often succeeds faster than operational maturity can keep pace. Consumer lag, partition drift, and configuration sprawl create dangerous blind spots. Learn how unified visibility, governance, and automation transform reactive Kafka operations into predictive control.

AI Coding Security Risks Demand Dependency Firewalls | Harness Blog

AI coding assistants accelerate development but can rapidly introduce vulnerable, malicious, or non-compliant open-source dependencies into your codebase. Harness Artifact Registry's Dependency Firewall acts as a registry-level control point, evaluating and blocking risky external packages before they enter your CI/CD pipeline—essential protection against modern npm-style supply chain attacks.
