  • RISC-V gains momentum as it moves from MCUs to Linux-friendly SoCs

    The open source RISC-V ISA has evolved quickly into silicon, thanks to help from companies like SiFive and Microsemi. SiFive’s HiFive Unleashed board should arrive less than two years after SiFive announced its first Linux-driven Freedom SoCs.

    It’s been two years since the open source RISC-V architecture emerged from computer labs at UC Berkeley and elsewhere and began appearing in soft-core implementations designed for FPGAs, and over a year since the first commercial silicon arrived. So far, the focus has primarily been on MCU-like processors, but last October, SiFive announced the first Linux-driven RISC-V SoC with its quad-core, 64-bit bit Freedom U540 (AKA U54-MC Coreplex). A few days ago at FOSDEM, SiFive opened pre-sales for an open source HiFive Unleashed SBC that showcases the U540.

  • SiFive releases Linux SoC processor and board

    SiFive Inc. (San Mateo, Calif.), a startup that is offering processor cores that comply with the RISC-V open source architecture, has launched a Linux-capable RISC-V based processor chip, the Freedom U540 SoC.

  • Chip Embarks As First Linux-Capable RISC-V Based SoC

    SiFive launches what it calls the industry's first Linux-capable RISC-V based processor SoC. The company recently demonstrated the first real-world use of the HiFive Unleashed board featuring the Freedom U540 SoC, based on its U54-MC Core IP. During the demo, SiFive provided updates on the RISC-V Linux effort, surprising attendees with an announcement that the presentation had been run on the HiFive Unleashed development board. With the availability of the HiFive Unleashed board and Freedom U540 SoC, SiFive has brought to market the first multicore RISC-V chip designed for commercialization, and now offers the industry's widest array of RISC-V based Core IP.

  • PIXO Pixel - Open Source LED Display for Makers

    Sean Hodgins is an inventor and maker interested in purposing current technologies in new and different ways. He’s currently running a crowdfunding campaign on Kickstarter for the PIXO Pixel, an open source RGB display that controls 256 LEDs.

  • AFRL, NextFlex leverage open-source community to create flexible circuit system

    Lightweight, low-cost and flexible electronic systems are the key to next-generation smart technologies for military as well as consumer and commercial applications.

    An Air Force Research Laboratory-led project in conjunction with NextFlex, America’s Flexible Hybrid Electronics Institute, has resulted in the first ever, functional samples of flexible Arduino circuit board systems made by using a flexible hybrid electronics manufacturing process, setting the stage for smart technologies for the internet of things and sensor applications like wearable devices.

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.
