HDR in Linux: Part 1

Submitted by Rianne Schestowitz on Friday 7th of May 2021 07:02:42 PM Filed under
Linux

In recent months I have been investigating high dynamic range (HDR) support for the Linux desktop, and what needs to be done so that a user could, for example, watch a high dynamic range video.

The problem with HDR is not so much that there is no material out there covering it, but that there’s a huge amount of material can be rather confusing. I thought it best to add more material that is probably also confusing, but may help me think through HDR better. The following content is likely wrong as I have no background in colorimetry, the human visual system, or graphics generally. I’d love to hear what makes no sense.

In this post I’ll cover what HDR is and why we care about it. In the next post, I’ll cover the work in specific projects that has been done to support it and what is left to be done.

  • 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.
