AMD and Intel: RdRand and Clear Linux Documentation

  • AMD Bulldozer/Jaguar CPUs Will No Longer Advertise RdRand Support Under Linux

    Not directly related to the recent AMD Zen 2 BIOS update needed to fix an RdRand problem (though somewhat related in that the original systemd bug report for faulty AMD RdRand stems from these earlier CPUs), but AMD has now decided to no longer advertise RdRand support for Family 15h (Bulldozer) and Family 16h (Jaguar) processors under Linux.

    The RdRand instruction will still work on capable CPUs, but the CPU ID bit is being cleared so that it won't be advertised for software explicitly checking for the support. Tom Lendacky of AMD reesorted to clearing the RDRAND CPU ID bit for 15h/16h processors (no impact for Zen, etc) due to RdRand issues cropping up after suspend/resume. Those issues have affected some users for a while and originate with the original AMD RdRand systemd bug report over problems following that cycle.

  • Clear Linux Project has a new documentation site

    The Clear Linux OS Docs team is happy to announce that our documentation site for the Clear Linux Project has moved to a Sphinx/reST site with the ubiquitous Read-The-Docs theme, consistent with many open source documentation projects.

  • Clear Linux Rolls Out Revamped Documentation

    While Arch Linux remains the gold standard for quality Linux documentation, Intel's Clear Linux has rolled out a new documentation web-site to assist new/existing users in making use of this performance-optimized and security-oriented Linux operating system.

Clear Linux launches a new documentation website

  • Clear Linux launches a new documentation website

    Clear Linux fans will now be able to have better access to more information about the operating system as Clear Linux announces a new and improved documentation website.

    New Linux users can be somewhat unfamiliar with the Clear Linux Project. Accordingly, let FOSSLinux give a brief introduction of this wonderful operating system. Powered by Intel, the Clear Linux OS is a Linux-based, rolling-release distro that has its eyes set on providing optimal performance and security. Other than that, users will also find this operating system to be manageable and customizable.

    Now that we’re done with its introduction let’s get to the actual news. The new Clear Linux documentation site is based on a Sphinx/reST framework and uses the Read-The-Docs theme, which you will find on most of the documentation sites out there. With this, it can be seen that Clear Linux wants to stay in the same lane as its competition.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
