  • How To Install and Configure Todoist in Linux Distributions

    The word Todoist is the phonetic short form of To-Do List, and it can be used for organizing work, tasks, and quick notes. The Todoist can remember all of your works for you and recall you when you need them. If you work for different clients, Todoist can also manage to remind you of the high prioritized tasks. Mostly, if you’re a Linux sysadmin, I’m sure there is too much work to do for you in the entire week.

    You can now use the Todoist tool on your Linux system to remind the tasks, share the load among others, customize workload, and keep a balance between your work and life. You can also use Todoist for managing your shopping, store, day-to-day life, and social gathering.

    The Todoist application is available for Windows, Mac, Linux, Android, and iPhones. It allows you to set labels, filters on the worklist, and even you can customize the Todoist theme based on your work category.

  • How to patch modules in Red Hat Enterprise Linux | Red Hat Developer

    Red Hat Enterprise Linux (RHEL), in version 8, introduced modules as a higher-level concept for packaging software stacks. Modules enable new features such as adding alternative versions of stacks, called streams. That's great, but what if you want to patch a stream? Is it possible? It is. Is it more difficult than patching non-modular software? Slightly. This article shows you how to patch a module stream while avoiding the invisible package problem.

  • 3 Ways to Remove Files from Trash on Ubuntu using GUI and Terminal

    By choosing files and documents and hitting the “Remove” key on the keyboard, users can remove all data. Those files are then moved to Junk, a computer location for discarded data. Deleted files remain inside the "Trash" folder unless you elect to clear it or restored the contents. Throughout this article, we'll look at the first choice: how and where to delete documents via Trash.

  • Get started with Argo CD | Opensource.com

    In a typical push-based deployment, tools like Ansible and Jenkins connect directly to the server or cluster and execute the provisioning commands. This approach works well when the cluster is accessible on the network and there is direct connectivity between your deployment server and the destination server. For compliance or security reasons, connectivity between the deployment tool and the cluster may not be possible.

    Argo CD is a pull-based deployment tool. It watches a remote Git repository for new or updated manifest files and synchronizes those changes with the cluster. By managing manifests in Git and syncing them with the cluster, you get all the advantages of a Git-based workflow (version control, pull-request reviews, transparency in collaboration, etc.) and a one-to-one mapping between what is in the Git repo and what is deployed in the cluster. This method is called GitOps.

  • 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.
