  • SiFive RISC-V Proven in 5nm Silicon

    Today, I am pleased to see OpenFive, a SiFive business unit that is the leading provider of customizable, silicon-focused solutions with differentiated IP, is continuing to make progress with AI design solutions with the creation of a reference design chiplet architecture using OpenFive Die-to-Die interface, OpenFive HBM3 IP subsystem, and SiFive 7-Series processor IP, for 2.5D-based SoCs. More details on the full announcement can be found on OpenFive’s announcement here, but today I want to call out the SiFive milestone of our first RISC-V processor core in 5nm.

  • SiFive Tapes Out Their First 5nm RISC-V Processor Core

    SiFive's OpenFive business unit announced today they have completed their first tape out of a RISC-V processor core using TSMC's 5nm process.

    This 5nm RISC-V SoC will be for "advanced AI/HPC" solutions using a chiplet architecture with SiFive 7-Series processor IP and OpenFive HBM3 IP subsystem.

  • SUSE Update Infrastructure Setup Guide for Cloud Service Providers

  • Linux 5.13 To Allow For OpenBMC Development With A Lower-Cost ASRock Rack Motherboard - Phoronix

    The Linux Foundation's OpenBMC project to provide an open-source BMC firmware stack is quite exciting for freeing this low-level aspect of servers, but finding a supported motherboard that works well with OpenBMC can be a challenge at this stage. Fortunately, Linux 5.13 is set to support a lower-cost motherboard option in hopes of boosting OpenBMC development/usage.

    Queued into the SoC "for-next" Git tree is support for the baseboard management controller on the ASRock Rack E3C246D4I motherboard.

  • Blog: kube-state-metrics goes v2.0

    kube-state-metrics, a project under the Kubernetes organization, generates Prometheus format metrics based on the current state of the Kubernetes native resources. It does this by listening to the Kubernetes API and gathering information about resources and objects, e.g. Deployments, Pods, Services, and StatefulSets. A full list of resources is available in the documentation of kube-state-metrics.

  • Local Storage: Storage Capacity Tracking, Distributed Provisioning and Generic Ephemeral Volumes hit Beta

    The "generic ephemeral volumes" and "storage capacity tracking" features in Kubernetes are getting promoted to beta in Kubernetes 1.21. Together with the distributed provisioning support in the CSI external-provisioner, development and deployment of Container Storage Interface (CSI) drivers which manage storage locally on a node become a lot easier.

    This blog post explains how such drivers worked before and how these features can be used to make drivers simpler.

    [...]

    The first problem is volume provisioning: it is handled through the Kubernetes control plane. Some component must react to PersistentVolumeClaims (PVCs) and create volumes. Usually, that is handled by a central deployment of the CSI external-provisioner and a CSI driver component that then connects to the storage backplane. But for local storage, there is no such backplane.

    TopoLVM solved this by having its different components communicate with each other through the Kubernetes API server by creating and reacting to custom resources. So although TopoLVM is based on CSI, a standard that is independent of a particular container orchestrator, TopoLVM only works on Kubernetes.

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.
