  • Download A Portion Of Youtube Video with Youtube-dl And FFmpeg

    Even though there are multitude of programs available to download and encode videos, I prefer to use Youtube-dl and FFmpeg.

  • Linux bluetooth HeadSet Audio HSP/HFP WH-1000XM3

    I am an archlinux user using Sony WH-1000XM3 bluetooth noise-cancellation headphones. I am also using pulseaudio and it took me a while to switch the bluetooth headphones to HSP/HFP profile so the microphone can work too. Switching the bluetooth profile of your headphones to HeadSet Audio works but it is only monophonic audio and without noise-cancellation and I had to switch to piperwire also. But at least now the microphone works!

    I was wondering how distros that by default have already switched to pipewire deal with this situation. So I started a fedora 34 (beta) edition and attached both my bluetooth adapter TP-LINK UB400 v1 and my web camera Logitech HD Webcam C270.

    The test should be to open a jitsi meet and a zoom test meeting and verify that my headphones can work without me doing any stranger CLI magic.

  • 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.
