  • Linux audio - only speakers or microphone available, not both

    Here we go. I am happy to have fixed the issue, but I am terribly disappointed that this kind of problem can or should occur in 2021. You might be inclined to blame hardware, and you might even search for specific audio issues with the AMD Raven/Raven2 Audio Processor, which could be a good indicative starting point. But in the end, it's not hardware stuff we ought to blame. I do not know why the PulseAudio configuration should be any different for this particular card on this distro, but in any case, you have this tutorial, so hopefully things will be all jolly from now on.

    If you're facing audio issues on your Linux laptop, try to debug your problem methodically. Does the audio work correctly in other operating systems? Does the audio work selectively in your distro? If so, do you have the right kind of configuration in place? Use the lspci and pacmd commands to try to figure out what's wrong, and then, you're far more likely to zero in on the right configuration changes for the audio subsystem. In my case, it was the "simple" matter of creating a new PulseAudio profile. Once again, big thanks to the ArchLinux Wiki folks. Party on, fellas.

  • Openbox tweaks and tricks – no {dbus,ck2,elogind,dm} no user services needed

  • How to Configure Static IP Address on Linux System

    A Static IP address is a 32-bit identification address of your network that never changes where the dynamic IP address changes frequently. Establishing a dial-up internet connection through the PPPoE method is more straightforward than configuring an internet connection through a static IP address. The ISP could often provide you an IPv4 address, sub-netmask, and gateway address to establish your internet connection. Suppose you are a newbie on internet configuration and not familiar with a Linux system’s network manager. In that case, it could be a bit trickier to configure a static IP address on Linux-based systems.

  • How to Mount and Use an exFAT Drive on Linux System

    As a Linux user, you probably already know that Linux uses the Ext4 journaling file system, where the entire operating system is stored inside the root directory. Other operating systems and a lot of digital gadgets use NTFS, Fat, Exfat, and other file systems. Here, the problem is Linux kernel doesn’t support the exFAT file system. Now, you might be fine with the Ext4, Fat and NTFS, and other file formats on your Linux system. But you need to know how to handle and mount an exFAT drive on your Linux system to use an exFAT Pendrive or flash drives.

  • Merging git branches on the command line and GitHub - The Linux Juggernaut

    In our previous articles on git branches we explained what are branches in git terminology. Branches provide a means to have a working copy of our code available in the master branch while we continue to make changes to it in a different branch. We also practically demonstrated how to create branches and work with them. In this article we will demonstrate how we could merge the work or updates that we’ve made while working in a branch with the master branch. The demonstration will consist of merging changes with the master branch on the command line as well as on a remote. For the purpose of this demonstration we will be using GitHub as our remote since we’ve already set it up and synced our repositories up there.

  • 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.

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.

  • 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.
