Linux at Home: Explore the Universe from your Garden

Filed under
Sci/Tech

In this series, we look at a range of home activities where Linux can make the most of our time at home, keeping active and engaged. The change of lifestyle enforced by Covid-19 is an opportunity to expand our horizons, and spend more time on activities we have neglected in the past.

Even though many European countries have made significant steps in relaxing some of the restrictions of daily life, the advice is to maintain social distancing rules. The big fear is that there will be a coronavirus resurgence. But it’s important that we don’t cocoonourselves, we need to protect ourselves and be supportive to others. There are many fascinating hobbies that can spark our imagination. Astronomy is a great example.

A widespread belief is that astronomy is an activity which cannot be enjoyed without paraphernalia like telescopes and other expensive equipment. However, astronomy is for everyone, and even with just the naked eye, it can become a fascinating and rewarding hobby for life.

It’s a learning hobby. Its joys come from intellectual discovery and knowledge of the cryptic night sky. But you have to make these discoveries, and gain this knowledge, by yourself. In other words, you need to become self-taught.

With the aid of open source software, budding astronomers can learn how to ‘read’ the stars, to know which constellations lie overhead, their trajectory throughout the seasons, and the legends ascribed to them. With the following software you can learn about the night skies of both the northern and southern hemispheres. I recommend Celestia, Stellarium, and AstroImageJ. For the first two programs, I’ve produced a short video showcasing them in action. The software is cross-platform.

  • 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.
