  • Announcing the Arduino IDE 2.0 (beta)

    The Arduino IDE is the well-known software we all use to program our boards. Its development started in 2005 based on the graphical interface of the Processing project and has never stopped since. During these years, countless hours of development by the Arduino team with the help of a vibrant community made the Arduino IDE the de facto standard for electronics prototyping. Thanks to an extensible framework based on modular board support packages, the IDE supports more than 1,000 official and non-official boards; it’s translated in 66 languages, mentioned by more than 3,000 books, and is still growing: during the last year, it was downloaded more than 39 millions of times. More than ever.

  • A neat way to add a reset button to Raspberry Pi Pico

    The Raspberry Pi Pico is a nice little board, but if you program in C language, you’d need to disconnect the micro USB cable each time you’d like to flash the UF2 firmware. That’s not convenient and could damage your board over time. The Raspberry Pi Foundation even decided to write a blog post explaining how to add a reset button to your Raspberry Pi Pico using a breadboard circuit.

  • Raspberry Pi CM4 Carrier Board comes with RS485/Modbus, CAN, 1-wire interfaces (Crowdfunding)

    Another day, another Raspberry Pi CM4 carrier board. Just like the TOFU carrier board, CM Hunter carrier board for Raspberry Pi CM4 targets industrial applications, but in a different way, as it focuses on industrial communication protocols with Galvanically-Isolated RS485/Modbus, 1-Wire, CAN 2.0B, and together with more common interfaces like Ethernet, HDMI, USB, etc…

    [...]

    The project will be open-source hardware with Eagle Schematic and PCB design files, custom libraries, BOM, part numbers, and custom Raspbian Image with all Python libraries and instructions released once the crowdfunding campaign is over.

    The Raspbian (Raspberry Pi OS) image comes with the FBCP driver for the display, and a demo user interface based on Python 3.7, PySide2 5.12, and QML 5.12 to showcase and control the Modbus, CAN, 1-Wire interfaces respectively using python-can, modbus_tk, and Pyownet open-source libraries, as well as the RTC and the relay.

  • 3.5-inch Atom x6000E embedded SBC features 3x GbE, 2x SATA, 6x USB, and more

    Several Elkhart Lake SBC’s integrate two Ethernet ports including Avalue ECM-EHL 3.5-inch SBC or Congatec Conga-PA7 Pico-ITX board with the former equipped with 2.5GbE and GbE ports, and the latter two GbE ports.

    But if your industrial project requires more Ethernet ports, iBase IB836 3.5-inch Atom x6000E embedded SBC offers three Gigabit Ethernet RJ45 ports, as well as two SATA ports, six USB interfaces, plus various display options, as well as M.2 and mPCIe expansion sockets.

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.
