    Fedora Linux 34, the latest version of the fully open source Fedora operating system, is now generally available.

  • Value range propagation in GCC with Project Ranger

    One of the optimizations GNU Compiler Collection (GCC) performs on C and C++ programs is value range propagation (VRP). VRP determines what subranges a variable can contain and uses that information to eliminate redundant calculations. This in turn makes programs smaller and run faster.

  • Red Hat Enterprise Linux 8.4 to focus on driving edge adoption - SD Times

    Red Hat announced new features coming to Red Hat Enterprise Linux (RHEL) 8.4, which will be released in a few weeks, at its Red Hat Summit virtual conference this week.

    According to the company, this release “refines the platform’s role as a lightweight, production grade operating system for edge deployments, adding new Linux container, deployment and management capabilities scaled for the needs of edge computing.”

    Red Hat recently released a report, “The State of Enterprise Open Source,” which showed that 72% of IT leaders are expecting open source to drive adoption of edge computing in the new two years. Red Hat Edge is a new effort being highlighted in RHEL 8.4 that aims to extend Red Hat’s cloud portfolio to the edge. This includes extending existing solutions like OpenShift, Advanced Cluster Management for Kubernetes, Ansible Automation Platform, Red Hat Integration, and Red Hat Data Services.

  • 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.
