  • What is an SBC?

    Most of the under-$200 SBCs offer varying degrees of open hardware support. Schematics and other open hardware files are typically available, and most offer community resources like forums and online tech support.

    Customized Linux and Android images are typically available, which are increasingly tied to mainline Linux. There is a lot of sloppy work out there in OS support, especially on the lower-cost models, but OS reliability is improving.

    The most popular OS choices for Linux SBCs are Ubuntu and Yocto Project, which is not a distribution but a standardized collection of components and libraries. Other desktop distros such as Fedora are sometimes supported on higher-end x86 SBCs.

    Linux continues to dominate the Arm SBC world and increasingly competes with Windows 10 in the larger market for commercial x86 SBCs. Low-power microcontroller-driven boards that run real-time operating systems such as FreeRTOS, tend to be more like SOMs (see the new Raspberry Pi Pico). Many Arduino boards, however, are more like SBCs.

    In both the Linux and RTOS MCU board markets, the open source RISC-V architecture has begun to make inroads, with new Linux-driven SBCs such as SiFive’s HiFive Unmatched. We will examine RISC-V in a future article.

  • Arduino launches Portenta Machine Control industrial control unit

    Arduino Portenta Machine Control is a low-power, industrial control unit powered by Arduino Portenta H7 board and designed to drive equipment and machinery through digital and analog I/O exposed through terminal blocks.

    The industrial control unit adds to the Arduino Pro family that was introduced in 2020 with support for the Arm Pelion IoT platform, the launch of the STM32H7-powered Arduino Portenta H7 industrial board, and joins another application-specific solution, namely the Arduino Edge Control board for smart agriculture launched last month.

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.
