  • Ubuntu 22.04 System Monitoring with Conky widgets

    Conky is a system monitoring program for Linux and BSD that runs on the GUI. It monitors various system resources to report the current usage of CPU, memory, disk storage, temperatures, users logged in, currently playing song, etc. in a sleek little widget on your screen. This way, you’re able to see at a quick glance how your computer’s components are being utilized.

    Conky is lightweight and highly configurable, so you’re able to run it without having a negative impact on your system or seeing it stick out like it doesn’t belong. We’ll show you how to get it installed on Ubuntu 22.04 Jammy Jellyfish and some configuration options to get it looking nice.

  • Firmus Supercloud sets a new standard for sustainable cloud computing with Canonical’s open infrastructure | Ubuntu

    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 global greenhouse gas emissions, and that number is rising. This is largely due to the inefficiency of traditional data centre designs. The worldwide average for data centre energy efficiency is 1.59 power usage effectiveness (PUE), which means that for every megawatt that is spent powering computers, an additional 590 kilowatts are required to run cooling systems. This value has been stagnant for some time, resulting in inefficient data centres that are costly to operate, costly to access, and costly to the planet.

    Firmus is solving the data centre efficiency and sustainability issue with an innovative new immersion cooling solution: submerging servers in a bath of non-conductive, biodegradable fluid that is approximately 1000 times more effective at wicking away heat than air.

    The immersion cooling technology has led to what is arguably the most efficient data centre design in the world, coming in at just 1.03 PUE. This is enabling Firmus to offer a public cloud service, Supercloud, at a price point significantly lower than the rest of the market. What’s more, Firmus’ data centre is located in Tasmania where it is powered by genuine grid connected renewable energy.

  • 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.
