  • SoM/baseboard combo forms ST Cortex A7/M4 hybrid-based SBC

    SeeedStudio has developed the Odyssey-STM32MP157C, an SBC comprised of an SoM based on ST’s STM32MP1 SoC and the Raspberry Pi-like NPI-STM32MP157C baseboard.

    SeeedStudio has built an SoM based on STMicroelectronics’ Arm Cortex A7/M4 hybrid SoC called the SOM-STM32MP157C, along with a Raspberry Pi “inspired” baseboard called the NPi-STM32MP157C. Together these products form a new SBC designated Odyssey-STM32MP157C. Although product details for the SBC yet to appear for on Seeed’s website at the time of this writing, specs and documentation are available on Seeed’s GitHub pages as well as distributor sites Digi-Key and Mouser. The SBC is targeted for applications such as consumer,industrial, white goods, medical and wearable devices.

  • Apollo Lake in-vehicle PCs have four PoE ports

    Nexcom’s “nROK 6222” and similar “VTC 6222” are rugged, Linux-ready in-vehicle computers with an Intel Apollo Lake SoC, 5x GbE (4x with PoE), 3x mini-PCIe, 2x SATA, 2x HDMI, and CAN, serial, VGA, USB 3.0, and GPS.

    Nexcom announced a nROK 6222 computer for rolling stock applications and a similar VTC 6222 system for more general-purpose in-vehicle usage. Both systems run Linux or Win 10 on an up to 2GHz, quad-core Atom E3950 from Intel’s Apollo Lake generation. They’re both designed to connect with IP surveillance cameras via 4x Power-over-Ethernet (802.3af/at) enabled GbE ports. They can also assist centralized fleet management applications with extensive wireless support.

  • The Future of Embedded Software

    As the world continues its steady march towards ubiquitous computing, almost everything from airplanes to toasters is being powered by embedded software. In fact, technology is so pervasive, we take connected homes, advanced medical equipment, and self-driving cars almost for granted.

    However, many of us who work in the industry have some misgivings about what this explosion in embedded software ultimately means. There are some very important issues that need to be openly discussed and solved before it’s too late.

    For instance, why are there no standards to ensure embedded products are designed with quality in mind? A washing machine breaking down due to poorly designed code is one thing, but what about a car? In an industry with no professional certification, who’s responsible for software-related tragedies? It’s easy to think that companies are sparing no expense to build and maintain critical software to the utmost degree of excellence – when we all know that the opposite may be closer to the truth.

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.
