  • Play the drums on Linux with Hydrogen | Opensource.com

    Much of today's music features the exacting work of a drum machine. The term might make you think of a drum set with mechanical levers and cranks armed with drumsticks, but all it actually refers to is a synthesizer programmed to play drum sounds. A good drum machine programmer (often also a drummer) can make a drum machine sound either hyper-robotic (if that's the sound the producer's going for) or almost human, with nuance and swing. Drum machines can be physical devices, like the famous Roland TR-808, TR-909, Alesis HR-16, and many others, but lately, they've been implemented as software. The excellent LMMS application contains a drum machine, and there's the drumkv1 plugin for DAWs like Ardour, Qtractor, and Rosegarden. But there's also the dedicated Hydrogen drum machine that has just one job, which it does very well, and has done for the past 20 years: be a great, fully-featured, and open source drum machine.

  • 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.

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.

  • 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.
