  • ODYSSEY expandable mini PC supports Win10, Linux and Arduino

    A versatile new mini PC is now available to order in the form of the ODYSSEY X86J4105864, offering an easy way to build Edge Computing applications with powerful CPU and rich communication interfaces, say its developers. The ODYSSEY X86J4105 mini PC is based on Intel Celeron J4105, is a Quad-Core 1.5GHz CPU that bursts up to 2.5GHz. There is also an onboard ATSAMD21 Core, an ARM Cortex-M0+ MCU that allows you to program Arduino on the x86 platform.

  • What is ESP32 and Why Is It Best for IoT Projects?

    ESP32 is a low-powered, low-cost microcontroller (MCU) board, with both Wi-Fi and Bluetooth built in, and is based on a dual-core processor mechanism. The first one is a powerful processor, such as a Xtensa LX6 (~240 MHz) with 512 KiB memory and the second an ultra-low coprocessor (ULP) with only 8 KiB memory designed to run when ESP32 is in deep-sleep mode.

    Other components include around 48 I/O pins (variable); an array of peripheral interfaces including temperature, hall effect, and capacitive touch sensors; and an 8-centimeter LCD panel, prominently visible here in an ESP32-WROVER board by Espressif Systems.

    [...]

    In fact, it runs on FreeRTOS, a leading operating system supported by Arduino. A big advantage of ESP32 is that it is readily supported by Arduino IDE as a “shield” which can be accessed from Board Manager. One can easily use functions from the FreeRTOS libraries when coding for the ESP32 within the Arduino IDE.

    Considering the scale of ESP32 applications which could be tiny, coin cell devices, it is better to use a predictable memory OS such as FreeRTOS rather than have its own complete OS, which is supported by Raspberry Pi, for example.

  • Kiwi TCMS is partnering up with Pionir

    We are happy to announce that Kiwi TCMS is going to partner with Pionir on the development of open source hardware for testers! Pionir is a free school focused on creating a new generation of digital leaders, an exponential culture and solving challenges using technology. They are located in Kikinda, Serbia.

    [...]

    Pionir will be developing hardware black boxes for teaching exploratory testing in cooperation with Kiwi TCMS. We have dedicated €2000 from our bounty program for students of the free school towards completing this project.

    The goal of the project is to produce at least 3 boxes and reference designs that will serve as a didactic tool for teaching, but also be free and open hardware, and as such, available to everyone to build from source.

    This project will be trusted to the students of the free school who will get opportunity to take part in the challenging process of building a digital appliance, from designing the machine logic, to develop and prototype hardware.

    The project includes designing, assembling, programming, documenting and delivering this hardware to us! Everything is expected to be open source: list of components, assembly instructions, 3D design files, source code, documentation and instructions! Our goal is that this will be relatively cheap and easy to build so everyone else can build their own boxes. During the next several months there will be new repositories created under https://github.com/kiwitcms to host the various boxes.

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.
