DuckDB: Not Quack Science | Ubuntu Summit 26.04
Could you process hundreds of gigabytes of data on your laptop, or tens of terabytes on a single server? DuckDB is an open source SQL database system, geared towards analytical workloads. DuckDB ships a state-of-the-art database architecture as a single package, that is available both as a command line tool and as an in-process library. Uniquely among databases, DuckDB focuses on user experience and portability, making it easy to set up almost anywhere.
Welcome Keynote | Ubuntu Summit 26.04
Welcome to Ubuntu Summit 26.04! In this welcome keynote, Mark Shuttleworth (CEO, Canonical), and Jon Seager (VP Engineering, Canonical), detail how Ubuntu is driving speed, safety, and community access in the era of agentic engineering. Learn how Canonical is balancing the need for rapid innovation with strict safety sandboxing through snaps, LXD, and microVMs. You'll also get a first look at what's in store for Ubuntu.
Introducing Workshop | Ubuntu Summit 26.04
In this talk from Ubuntu Summit, Dmitry Lyfar (Engineering Manager at Canonical) introduces Workshop: a new solution for launching composable, secure, and fast development environments on Ubuntu in a single command. Learn how to create sandboxed, reproducible environments for running agents with different development stacks consistently and securely. Ubuntu Summit 26.04 is a showcase for the innovative and the ambitious.
Using Bootc to Manage Ubuntu Hosts | Ubuntu Summit 26.04
What if you could manage your Ubuntu hosts the same way you manage your containerized applications? Managing Ubuntu hosts traditionally means configuration management, package updates, and drift control using tools like Puppet, Chef, or shell automation. Bootc streamlines the process. A Cloud Native Computing Foundation (CNCF) Sandbox project, bootc lets you define your Ubuntu systems as OCI container images and deploy them consistently across bare metal, virtual machines, edge devices, or cloud environments.
Introducing Workshop: launch sandboxed development environments on Ubuntu with a single command
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 workflows across development machines and deployment pipelines, and less time managing dependencies.
Decoding design: How design and engineering thrive together in open source
Open source thrives on engineering-driven processes. Fast feedback loops, terminal tools, Git workflows: they’re the lifeblood of how we build software in the open. But for software to truly excel, we need to create user experiences that empower people to use them. I wanted to bring this conversation into the spotlight as part of Canonical’s Open Design initiatives. What better way than at FOSS Backstage 2026 Berlin?
Ubuntu Core 26 fleet observability
What is Ubuntu Core? Ubuntu Core is a minimal and strictly confined variant of Ubuntu powering devices around the world. Ubuntu Core 26 now integrates with the Canonical Observability Stack, streaming device logs and metrics to centralized Grafana, Loki, and Prometheus infrastructure, deployable in the cloud or on-premise, without burdening the device's primary workloads.
Canonical announces fully Managed Kubeflow AI operations platform on the Microsoft Azure Marketplace
Canonical, the publisher of Ubuntu, today announced the general availability (GA) of Managed Kubeflow on the Microsoft Azure Marketplace. This solution enables AI teams to get a fully managed, production-ready MLOps platform in their own tenant. Upstream Kubeflow is a powerful tool for machine learning, but it remains notoriously challenging to deploy and maintain.
Developing web apps with local LLM inference
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 applications; one where the model lives inside your app, not behind a pay-per-token HTTP call.
