  • Ubuntu Remote Desktop: How to Set Up and Connect to it

    This step-by-step guide explains how you can enable an Ubuntu remote desktop so that you can access and control it remotely.

    Remote Desktop is a service that allows you to take over and use another computer remotely. In Ubuntu, it can be enabled on a graphical client machine to control a host machine. This feature is beneficial for users who are using a GUI interface or are not familiar with a command line.

    In this tutorial, we walk you through the process of setting this up and then connecting to that Ubuntu remote desktop via the Remmina remote desktop client.

  • Open Source Robotics Challenges – Planning for Security

    Open Source Robotics Challenges is a series of blogs that will share guidelines and advice for open source companies to overcome market barriers.

    We will touch on topics regularly raised by companies in our open source community such as security awareness, prototyping strategies, safety architecture, adoption and more. Our aim is to help organisations overcome the barriers associated with open source adoption in robotics so they can experience the inherent benefits that come with open source technologies. Agility, modularity and adaptability are some of the biggest benefits that open source robotics has been bringing to the field. This first blog will talk about security and security compliance.

  • Ubuntu Blog: Snapcraft for Windows – Preview [Ed: Canonical works for Microsoft]

    Two weeks ago, Snapcraft reached its fifth milestone release, 5.0. This version brings in a number of significant changes, including the removal of the base (core) snap, which has been relegated to the 4.X channel track. For snap developers, especially those working in mixed environments, the availability of the first preview release of Snapcraft for Windows(!) will more likely be the interesting piece of good news.

    Since its inception, the goal of Snapcraft has been to provide a robust, friendly development platform, regardless of your choice of operating system. The original Linux support has since been extended to macOS and now, Windows. You can build your snaps inside a Windows system, or upload them to the store, without having to have a Linux machine handy.

    [...]

    Snapcraft for Windows is an important addition to the snap ecosystem, offering developers across the operating system board to create and publish their applications with ease. At the moment, there might be some rough edges, but you can already make decent progress and test the functionality, including store-related commands and perhaps even build operations. We’d also appreciate feedback, so if you have anything to share, please join our forum and let us know what you think.

  • 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.
