  • Cluster API to the Rescue: An Easier Way to Manage Your Kubernetes Clusters

    In less than a generation, we’ve gone from bare-metal servers to virtualization to containers. It’s a story of expanded possibilities aided by stakeholder communities coming together to solve problems. Over time, processes have become easier and more efficient for end users. We’ve learned to orchestrate containers with Kubernetes, and now we can manage Kubernetes clusters and their associated infrastructure needs across multiple cloud providers (and hopefully on-premises) with Cluster API.

    Looking back to how we got here, the path is entirely logical: physical servers were once underutilized. They frequently ran only one application per physical server, leaving a vast majority of their computing power just sitting idle.

    Virtual machines came about to let you convert your underutilized physical servers into appropriately sized virtual servers. They reduced waste and made things easier: You were able to pack multiple virtual machines into a single physical server. With virtual machines, you could increase density and reduce cost.

  • IWD 0.18 Wireless Daemon Brings Fast Initial Link Setup

    Released this weekend was IWD 0.18 as the latest version of the Intel-developed wireless daemon for Linux systems.

    The main feature with IWD 0.18 is support for FILS, the Fast Initial Link Setup. Fast Initial Link Setup is part of the 802.11ai specification for allowing a WLAN client to setup a secure link within 100ms.

  • Donating 5 minutes of your time to help the LVFS

    For about every 250 bug reports I recieve I get an email offering to help. Most of the time the person offering help isn’t capable of diving right in the trickiest parts of the code and just wanted to make my life easier. Now I have a task that almost anyone can help with…

    For the next version of the LVFS we deploy we’re going to be showing what was changed between each firmware version. Rather than just stating the firmware has changed from SHA1:DEAD to SHA1:BEEF and some high level update description provided by the vendor, we can show the interested user the UEFI modules that changed. I’m still working on the feature and without more data it’s kinda, well, dull. Before I can make the feature actually useful to anyone except a BIOS engineer, I need some help finding out information about the various modules.

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.
