  • Reasons Kubernetes is cool

    When I first learned about Kubernetes (a year and a half ago?) I really didn’t understand why I should care about it.

    I’ve been working full time with Kubernetes for 3 months or so and now have some thoughts about why I think it’s useful. (I’m still very far from being a Kubernetes expert!) Hopefully this will help a little in your journey to understand what even is going on with Kubernetes!

    I will try to explain some reason I think Kubenetes is interesting without using the words “cloud native”, “orchestration”, “container”, or any Kubernetes-specific terminology Smile. I’m going to explain this mostly from the perspective of a kubernetes operator / infrastructure engineer, since my job right now is to set up Kubernetes and make it work well.

  • Mining Ethereum With AMD Threadrippers Paired With Four RX Vega 64 GPUs

    If you do not have time to read the full article here the short version in one sentence: No, it is not practical to run Ethereum on AMD Vega 64 graphics cards on Linux because the ROCm OpenCL stack in the AMDGPU-PRO 17.30 is very slow in Ethereum so the whole system with four Vega64 cards make 16-23Mh/s and even a single old AMD-RX470 with the old Closed-source OpenCL AMDGPU-PRO stack run ~20+ Mh/s... This all could be the effect of the exponential function Ethereum-ICE-AGE Bomb...

  • Chef Habitat Builder Debuts for Container Cloud-Native App Deployments

    DevOps vendor Chef announced the launch of its Habitat Builder software-as-a-service (SaaS) offering on Oct. 9, providing new automation capabilities for developers who work with containerized cloud-native applications.

    Habitat Builder is an extension of Chef's open-source Habitat automation technology that debuted in June 2016. With the original Habitat project, Chef provided developers with tools to help automate package code for different platforms. The new Habitat Builder effort goes a step further, providing a SaaS platform for developers to both build and deploy container applications for different cloud and container orchestration platforms.

  • fwupd hits 1.0.0

    Today I released fwupd version 1.0.0, a version number most Open Source projects seldom reach. Unusually it bumps the soname so any applications that link against libfwupd will need to be rebuilt. The reason for bumping is that we removed a lot of the cruft we’ve picked up over the couple of years since we started the project, and also took the opportunity to rename some public interfaces that are now used differently to how they were envisaged. Since we started the project, we’ve basically re-architected the way the daemon works, re-imagined how the metadata is downloaded and managed, and changed core ways we’ve done the upgrades themselves. It’s no surprise that removing all that crufty code makes the core easier to understand and maintain. I’m intending to support the 0_9_X branch for a long time, as that’s what’s going to stay in Fedora 26 and the upcoming Fedora 27.

  • Fwupd 1.0.0 Released To Advance Linux Firmware Updating

    Richard Hughes has announced the release of fwupd 1.0.0 today, the utility increasingly being used by many vendors for supporting updating of device firmware/microcode on Linux.

    With fwupd 1.0, there is ABI breakage as they removed a lot of cruft that built up over the years and also sought to improve some of the interfaces for this firmware updating project and its daemon. Fwupd 0.9 meanwhile will continue to be maintained for existing users not yet migrating to v1.0.

  • Letrs – A Cloud-Based Font Manager for Developers and Designers

    Letrs is a beautiful cloud-based font manager for developers and designers alike. It is also an ever-growing catalog of Typefaces which you can search for and activate to use on your computer and in your projects.

    It features a minimalist User Interface with a green, black, dark blue, and white color scheme. As you would expect from a cloud-based application, it works with an online account to which all your selected and uploaded fonts, teams, and search history is saved.

  • KMail User Survey Results, Part 1

    Back in August, we ran a survey to get input from our users and get a better understanding of how they use KMail. First, let me start by thanking everyone who took their time to fill in the survey. We collected over 3000 responses which is much more than we expected. Thank you very much! We got some interesting numbers and data from the survey, which I’ll analyze later, but to my big surprise, the most interesting part was the comments that many of you left at the end of the survey. We got over 1000 comments which provided us with a consistent feedback from the userbase. In this and the next blog posts, I want to address the common themes, complaints, and remarks that appeared in the comments, address the concerns raised and present some action plans that we are going to take to address those.

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.
