When you need the numbers just right – benchmark and profiling applications in the Snap Store

The world of software is a vast and complex one, often too difficult to easily assess by human intuition alone. Which is why detailed and accurate measurements of software behavior are essential in helping us understand and gauge how well our applications perform. The Snap Store has a fair share of productivity tools and utilities,

Migrating the Launchpad Keyservers from SKS to Hockeypuck

Ubuntu and Launchpad use OpenPGP keys heavily. Each source package is signed with the uploader’s key, and binary and source package downloads from Ubuntu’s primary archives and from users’ Personal Package Archives (PPAs) are indirectly signed by the publisher process with per-archive keys of its own. Access to Launchpad’s bug-manipulatio

MAAS CLI-only machine creation

The whole point of MAAS configuration is to get machines deployed. If you read the previous post in this series, you know how to install MAAS and do basic configuration using only the MAAS Command-Line Interface (CLI).  So far, so good, but now we need to enable networking and create some machines. Enabling DHCP The

Forecasting the future of cloud with OpenStack experts

OpenStack, the cloud computing platform, has proved to be a beacon of success for open source. It rounds off 10 years in existence this year, a period which has seen it reach nearly 200 countries, and we want to look ahead to what the future holds for the technology.  We’ve spoken to a number of

Install Amazon EKS Distro anywhere

One install, one cluster, snap! Today, we’re excited to announce that EKS is available outside of AWS, on any Ubuntu system, with the EKS snap. This announcement builds on the existing collaboration between Amazon and Canonical to ensure the quality, security, and usability of Ubuntu-based EKS clusters on AWS. “Amazon EKS Distro (EKS-D) b

Canonical’s LTS Docker Image Portfolio is now available on Amazon ECR Public

Today, Canonical announced the availability of its curated set of secure container application images on Amazon ECR Public, complementing the current offering. Multiple registries, one product Developers now also have access to the LTS Docker Image Portfolio from the Amazon ECR Public registry. Free and commercial versions of the hardened

CLI-only MAAS operation

MAAS provides a state-of-the-art User Interface (UI), which is relatively simple to use, if the required inputs are known and understood. You may be less familiar with the MAAS Command Line Interface (CLI), which is actually more robust, providing additional functionality that’s not accessible via the web UI. In this series of blog posts,

Productivity corner: offline translation

Language translation. Easily said, not easily done. Human languages have evolved over the past 30,000 years, tightly coupled to culture and collective memories of peoples, which is why, even today, we often struggle with fine nuances of meaning and context, especially when they need to be expressed in another language. But then, if we str

Exploring ROS 2 Kubernetes configurations

Kubernetes and robotics make a great match. However, as we have seen, robots running ROS 2 can be tricky to set up on Kubernetes. This blog series has explored running ROS 2 on Kubernetes, set up a simple talker and listener, and distributed that demo across three machines. The configurations presented may not quite fit

Distribute ROS 2 across machines with MicroK8s

Introduction Our simple ROS 2 talker and listener setup runs well on a single Kubernetes node, now let’s distribute it out across multiple computers. This article builds upon our simple ROS 2 talker / listener setup by running it on multiple K8s nodes. At the completion of this setup expect to have a ROS2 Kubernetes

Cybersecurity defenses for IIoT

Cybersecurity attacks on industrial IoT solutions can have detrimental consequences. This is the case because IoT devices record privacy-sensitive data and control production assets. Therefore, demonstrable trustworthiness is prerequisite to IoT adoption in industrial settings. Fortunately, IT security is a mature field. Experts have iden

Mark Shuttleworth on overcoming software complexity

While today we see an enormous amount of incredible software being published, both by tech giants and niche providers, there is a significant lag in the telco industry’s ability to leverage it.  The promise of a software-defined technology landscape is, of course, agility.  But what is the main factor preventing telecommunications enterpr

Edge computing is dead, long live micro clouds and IoT gateways

“The King is dead, long live the King.” It might be my french roots speaking, but it seems that actual use cases are replacing King Edge, and it might be for the best. Warning; do not read this blog if you’re particularly sensitive about edge computing (and if you don’t know what this is about,
