My Little Contribution to GNOME 40

Submitted by Roy Schestowitz on Monday 10th of May 2021 05:29:10 PM Filed under
GNOME

GNOME 40 is finally out and I'm happy to say a small contribution of mine made it into the release. My contribution adds a new feature to GNOME System Monitor version 40. Few articles about GNOME 40 mention it, but some power users might find my contribution useful.

This new feature essentially turns GNOME System Monitor into a graphical user interface for GNU Taskset, allowing you to set or adjust the CPU affinity of any process using a simple check box dialog window similar to how it's done in the Windows Task Manager.

To use this new feature all you need to do is right click any process and then click the "Set Affinity" menu item, this will bring up the CPU affinity dialog with check boxes for each processor core. These check boxes will be prefilled/auto-checked based on the process' current CPU affinity. Check or uncheck specific cores, then hit apply and you've successfully adjusted which CPU cores the process is allowed to run on.

  • 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.
