  • Ubuntu Blog: Embedded systems: the advent of the Internet of Things – Part II

    This is the second part of the two-part blog series covering embedded Linux systems and the challenges brought about by the proliferation of Internet of Things (IoT) devices. In Part I, we surveyed the embedded ecosystem and the role Linux plays within that space. This blog takes you on the next step in the journey, where we explore the most demanding challenges facing manufacturers of tightly embedded IoT devices.

  • CyberDog: a four legged robot revolution with Ubuntu

    Late this year, Chinese tech giant Xiaomi unveiled CyberDog: a quadrupedal, experimental, open-source robot that the firm claims will improve the robot development environment and promote the development of the robot industry. Today, Canonical dives into the specifications of this four legged robot and discover how Ubuntu is helping the device become an open source technological platform.

    Xiaomi has a clear vision for its product. As Huang Changjiang, PM at Xiaomi, explains, “CyberDog is developers’ technological partner from the future. It equips inhouse-made high-performance servo motors, high computing ability, with built-in AI for visual detection system and voice interaction system, supporting a variety of bionic motion gestures.”

  • ZeroDown® Software Targets Open Source with New Canonical Partnership

    As businesses around the world and in every major industry define and accelerate their cloud strategies, the lack of open, flexible and complete high availability has become a major concern. The ZeroDown platform, built upon Canonical’s industry-leading operating system, Ubuntu, aims at integrating into Canonical’s broader Charmed OpenStack platform with its ZeroDown Ultra High-Availability TM Software, eliminating downtime and data loss for its customers, running seamlessly through planned or unplanned downtime events.

  • Data centre networking: what is OVS? | Ubuntu

    In one of our preceding blogs, we spoke about Software-Defined Networking (SDN) and the key drivers behind it. Virtualisation is one of the fundamental aspects that characterises SDN, and has influenced the architecture of network switching in the data centre. OVS (Open vSwitch) is a fundamental component of modern and open data centre SDNs, where it aggregates all the virtual machines at the server hypervisor layer. It represents the ingress point for all the traffic exiting VMs, and can be used to forward traffic between multiple virtual network functions in the form of service chains. Let’s take a closer look in order to understand what OVS is.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
