This blog post continues with the previous blog post about design patterns and the software operator pattern. In this part, this post takes a closer look at the description of the software operator pattern. What is a design pattern? Over the years, the software development and programming community developed a common understanding of desi

In the early days of software development, computers were sold with compilers and interpreters. Users wrote mostly their own small programs instead of buying software. During that time, most didn’t even consider downloading software as only a few were connected to mailboxes or the UUCP network. Most of the software was provided by the com

They implement operational tasks covering everyday application management. They help human operators, administrators to run their applications efficiently and effectively. On Opera

March 31, London – Canonical today announced the general availability of OpenStack Yoga on Ubuntu 22.04 Long Term Support (LTS) Beta and Ubuntu 20.04 LTS. This new version of OpenStack sets a foundation for next-generation, highly performant infrastructure as needed by telco NFV, media streaming, traffic analysis and HPC services, using S

Concept design is the fundamental of interaction design and the deepest level of design decisions. A concept in this context is described as a bridge between the designer and the users, who will only be able to make effective use of the interface if they grasp the underlying intent of the concept that is designed. 

An embedded device is a hardware and software system that performs a dedicated function within a larger computer system. It is typically resource-constrained and comprises a processing engine.  The software of an embedded Linux system runs on top of the Linux kernel, the fundamental core of the OS with complete control over everything occ

When talking about containers, a common confusion for potential users of LXD is that LXD is an alternative to Docker or Kubernetes. However, LXD and Docker are not competing container technologies, and they tend to serve completely different purposes. In this blog, we’ll briefly discuss the differences and the suitable use cases for both.

Getting started with software can be confusing – depending on the complexity of the software, of course. Despite the extensive documentation available for Charmed Operator SDK and Juju some just prefer to watch video material to start with. So, let’s take the opportunity to have a look at available tutorials and presentations available on

A key principle of open source computing is the ability for users to directly engage with development efforts, the primary avenue being through the use of bug reporting. Bug reports are a critical component to the success of open source projects world-wide, though how to write one successfully can be, admittedly, somewhat vague. In this

It’s Wednesday, and you have less than 2 days to make the quarter. Busy month with no time to catch up with the latest info? No problem! Get up to speed with this curated list of bite-sized chunks of IoT news. In case you missed it, here is the State of IoT from last February!

In blogs one and two of this series, we covered how far we’ve come from the earliest smart homes, including older technologies and standards, and smart-home ideas that covered the gamut from innovative to total head-scratchers. We also covered the smart home landscape today, and what developments are on the immediate horizon. Here, we’ll

March 29th, 2022—Canonical, the publisher of Ubuntu, announces that Firmus, the Australian cloud infrastructure provider that is revolutionising data centre technology, has built its ultra-efficient and sustainable public cloud on Canonical’s Charmed OpenStack and Charmed Kubernetes. Data centres are responsible for a staggering 2% of glo

We now deliver Ubuntu Frame, a display server for embedded devices that makes it easy for developers to deploy their graphics applications on Linux. Ubuntu Frame simplifies the development of embedded displays such as digital signage solutions, kiosks, IoT devices, robots, and more. In this blog, we will discuss the migration from mir-kio

In part one of this series, we covered how far we’ve come from the earliest smart homes, including older technologies and standards, and smart home ideas that covered the gamut from innovative to total head-scratchers. We also talked about the DIY movement in the present day and the role of open source in the smart

Changing our language If you follow Canonical’s code and documentation, you may have noticed that we’re slowly changing some common computing terms. You might wonder what has caused these changes. You might ask why Canonical is putting in the effort to make this more inclusive language stick. The changes at Canonical are part of a
