  • An introduction to Linux virtual interfaces: Tunnels

    Linux has supported many kinds of tunnels, but new users may be confused by their differences and unsure which one is best suited for a given use case. In this article, I will give a brief introduction for commonly used tunnel interfaces in the Linux kernel. There is no code analysis, only a brief introduction to the interfaces and their usage on Linux. Anyone with a network background might be interested in this information. A list of tunnel interfaces, as well as help on specific tunnel configuration, can be obtained by issuing the iproute2 command ip link help.

  • A Partner’s Guide to Red Hat Summit

    Each year at Red Hat Summit we highlight the innovative and thought-provoking case studies and success stories coming from our partner network. Just as open source wouldn’t be the same without the community, Red Hat wouldn’t be the same without our partners. They play an integral role in our success and support our Red Hat Summit. For that, we want to say thank you.

    If you’re a partner and it’s your first (or your fifth time) going, a little planning can go a long way to helping you make the most of your time at the premier enterprise open source technology conference. Here are a few tips as you get ready to join us in Boston.

  • The making of Creating ChRIS: Creating and producing an original video series

    Rachel Rooney, producer, and Dave Baeumler, associate creative director, discuss building an original video series and how it contributes to the company’s marketing efforts. Dave breaks down the decision to do chapertized content versus creating one video asset, and Rachel walks through the logistical challenges and the unpredictability of being on set.

  • Setting kernel command line arguments with Fedora 30

    Adding options to the kernel command line is a common task when debugging or experimenting with the kernel. The upcoming Fedora 30 release made a change to use Bootloader Spec (BLS). Depending on how you are used to modifying kernel command line options, your workflow may now change. Read on for more information.

  • Fedora's Mesa Drivers Have Been Running Slower As They Were Accidentally Debug Builds

    It turns out Fedora 29's Mesa 19.0 packages have recently been shipping in a "debug" mode since they switched to using the Meson build system and that has been leading to slower performance.

    As is generally the case when building in a "debug" mode, various assertions and other extra validation paths are exposed and that can greatly influence the performance of the resulting binaries in code-bases like Mesa and their OpenGL/Vulkan drivers. Fedora 29 has mistakenly been shipping their production Mesa packages under a debug build when using the Meson build system.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
