Tokens per watt (TpW) – the measure of useful AI work produced per watt of energy consumed – is the metric at top of mind for CEOs, heads of AI, and infrastructure teams alike. With the tremendous cost of GPU clusters, extracting as much value as possible from the expense is critical. But in the

Welcome to this blog series which explores innovative uses of Ubuntu Core. Throughout this series, Canonical’s Engineers will show what you can build with our releases, highlighting the features and tools available to you. In this blog, Asa Mirzaieva, engineer from the Silicon Alliances team, will show you how to deploy optimised AI model

Introduction One of the important offerings of the RISC-V Instruction Set Architecture (ISA) is the ability to customize and extend the base instruction set. An initial reaction to hearing this is often to worry about software portability and compatibility, since if every RISC-V CPU  offers a slightly different set of instructions, softwa

AMD ROCm is now available in Ubuntu 26.04 LTS. Learn what how to make the best of it, and find out what this will mean in the coming years for development in Ubuntu.

Microsoft has announced the preview of Azure Cobalt 200, its second-generation custom Arm silicon. Learn how Ubuntu and Ubuntu Pro support these new VMs from day one, offering seamless deployment, long-term security maintenance, and Kernel Livepatch without requiring engineering or platform changes

When distributed workloads stall because nodes cannot exchange small messages quickly and consistently, the network is the limiting factor. How do you solve that problem? InfiniBand offers one solution. InfiniBand is an interconnect, meaning the end-to-end communication system that links compute, storage, and accelerator nodes. It is impl

A 12-year-old bug in libnss-db caused getent enumeration to slow to a crawl – and showed how far expert support can go when a customer brings the right evidence and the right question.

By packaging OpenShell as a snap, Canonical is enabling enterprises to confidently run next-generation agentic workflows across local devices, hybrid environments, and private clouds.

Canonical and Google Cloud announced the availability of certified Ubuntu images for Google’s Cloud TPU Virtual Machines.

Most modern datacenters are inherently heterogeneous. VMware environments coexist with container platforms, databases, and other bare-metal workloads, often on the same hardware over several years. Servers are bought once, but their role changes as requirements evolve. However, ESXi (the VMware hypervisor) provisioning is often handled se

The purpose of this guide is to highlight the key differences between Apache Spark 3 and Spark 4, and provide advice on how to plan a migration. Let’s get started. The biggest changes Let’s talk about the biggest changes between Apache Spark 3.x and Spark 4. Scala 2.12 no more First up, there’s no support

Developers now benefit from consistency and repeatability for cutting-edge workflows, including agentic AI. Today, Canonical announced the release of Workshop, a solution for launching development environments with a single command. These environments are configured once, and can be reproduced on different machines. This means consistent

In the lead-up to Ubuntu Summit 26.04, Canonical and Arm are collaborating to certify the new Arm AGI CPU on Ubuntu 26.04 LTS (Resolute Raccoon). Learn what this means for developers and agentic AI.

I’ve yet to meet a developer that enjoys working with metered AI APIs. The need to pay for every API call in development works in direct opposition to the ethos of rapid iteration, and it’s easy for the costs to get out of hand. That’s why Canonical has created a different approach to building AI-powered

A local privilege escalation (LPE) security vulnerability in the Linux kernel, codename “PinTheft,” was publicly disclosed on May 19, 2026. The vulnerability was fixed in the mainline Linux kernel tree. A proof-of-concept exploit was published along with public disclosure. This has been assigned the CVE ID CVE-2026-43494; other discoverin

Canonical has announced the general availability of Managed Kubeflow on the Microsoft Azure Marketplace. This fully managed MLOps platform allows enterprise AI teams to deploy a production-ready environment in under an hour, eliminating infrastructure maintenance.
