Canonical’s recipe for High Performance Computing

HPC Ubuntu tech blog

In essence, High Performance Computing (HPC) is quite simple. Speed and scale. In practice, the concept is quite complex and hard to achieve. It is not dissimilar to what happens when you go from a regular car to a supercar or a hypercar – the challenges and problems you encounter at 100 km/h are vastly ...

High Performance Computing – It’s all about the bottleneck

HPC Ubuntu tech blog

But after giving it some thought, you may realize that, in fact, they do share a rather similar theme. Two words: Ubuntu Summit.

What happens in the Craft team stays in the Craft team … until today

Ubuntu Ubuntu tech blog

Snapcraft, Charmcraft, Rockcraft … you may have heard of these tools, but have you ever wondered how – and by who – they are developed? These tools are the intellectual and keyboard-driven product of Canonical’s Craft team. Officially, the team’s name is *Craft, and the asterisk symbol can easily be seen as a “star” (The ...

Hold your horses, I mean snaps! New feature lets you stop snap updates, for as long as you need

Desktop Ubuntu tech blog

One of the core aspects of the snap ecosystem is the built-in, robust auto-update mechanism. Whenever there is a snap update available in the Snap Store, the snapd service will apply it, keeping your software patched and up to date. Most of the time, this works great. In some scenarios, though, this may not be ...

Snaps & better refresh notifications

Desktop Ubuntu tech blog

Automatic updates grant snap users an ability to receive timely patches to their software, both in aspects of security and functionality. This can be rather useful and convenient, especially for applications that have online access.
