  • PipeWire Audio Server on openSUSE Tumbleweed

    Linux audio has been considered a sore-spot with some audiophiles. Personally, I have been very happy with Linux Audio since about 2009 or 2010 or so and enjoyed its continual improvements as the project has matured. The high point for PulseAudio has been the intuitive, input / output switching. The downside has been the latency (which I happen to think has been an inflated claim) and the lack of granularity control on sound sources. Jack Audio has been the audio system for professional users with the benefit of lower latency and more granular control. In general, PulseAudio was the “consumer grade” solution with Jack Audio for the pros and require pro-level knowledge.

    The promised solution for Linux has been PipeWire which combines the benefits of both. With some distributions just now starting to include it, some by default, others as an option, I thought it was time to see how it would work on my EliteBook running openSUSE Tumbleweed. The impetus for this decision is, all of a sudden, my Bluetooth headphones started to have terrible quality and I figured, I have nothing to lose here. I can always just roll back my installation if I totally break it.

  • 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.
