  • Years Late: Linux 5.5 To Offer Mainline Support For SGI's Octane MIPS Workstations

    The Linux 5.5 kernel due out as stable in early 2020 will finally have mainline support for the MIPS-powered SGI Octane and Octane II workstations that originally ran with SGI's IRIX operating system about two decades ago.

    There have been out-of-tree patches for running Linux on the SGI Octane MIPS-based systems while Linux 5.5 is set to finally have this support mainlined for these two decade old workstations should you still be running the hardware and looking for something else besides IRIX or support in other platforms like OpenBSD. Mind you, these workstations were already succeeded by the SGI Octane III a decade ago with Intel x86.

  • The Linux Kernel Seeing Backport Progress Finally For The "$1.5 Million Dollar Bug"

    Several weeks ago we wrote about a kernel fix for Linux 5.4 to address performance issues for highly-threaded Linux software running under CFS quotas. The fix can yield up to a 30x improvement in performance and one company estimated the impact of the bug cost them at least $1.5 million USD in extra resources/hardware. But now it looks like it will soon appear in a Linux 5.3 point release and possible back-ports to earlier kernels.

    The CFS quota performance issue was spotted with Kubernetes workloads that make use of a CFS scheduler quota to restrict CPU shared resources. The bug was highly-threaded software in turn not getting their fair access to the CPU leading to higher latency and lower performance.

  • Linux Day 2019 @ Bari: A Retrospective

    How about Fedora? Well, Fedora was ever present during the event. We placed gadgets on the registration desk, dedicated a special lunch menu entry, tried to install it everywhere we could put our hands on people PCs. We also used Fedora to win a Cybersecurity challenge! You may ask: how did we do so many things? Don’t worry, let’s see them with some quick photos

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.
