  • Developing Qt5 applications natively on Wind River Linux

    Wind River Linux provides the technologies essential to building a flexible, stable, and secure platform for your embedded devices.

    Based on OpenEmbedded releases from the Yocto Project, it is designed to let you customize your platform to include only the packages and features you need. Powered by bitbake, it provides the ability to build an entire Linux distribution from source by following repeatable recipes. This is really powerful, but can be foreign to application developers that already have a workflow they are comfortable with.

    Developers building graphical user interfaces (GUI) have their own set of tools that they rely on. Often they prefer to use an Integrated Development Environment (IDE) tailored to the language and frameworks they are working with. Typically this IDE and the tools it uses are running natively on the same platform they are building for.

    Fortunately, these developers can still do this on Wind River Linux. This tutorial describes building Wind River Linux with the GCC toolchain and Qt Creator included to enable native application development.

  • Udoo Bolt Gear mini-PC launches with Ryzen V1000 Udoo Bolt SBC

    Seco has launched a $399 “Udoo Bolt Gear” mini-PC kit built around its Ryzen Embedded V1000 based Udoo Bolt SBC. The $399 kit includes a metal case, 65W adapter, and a WiFi/BT M.2 card.

    A growing number of open-spec, community-backed SBCs ship with optional. and in some cases, standard enclosures, but most of these are simple plastic cases. Seco’s new Udoo Bolt Gear mini-PC, which is based on its Udoo Bolt SBC, provides a metal case, a power adapter, US and EU cables, a VESA mount, and a WiFi/BT kit. There are also plenty of vents to help the SBC’s standard fan cool AMD’s Ryzen Embedded V1000 SoC.

    [...]

    The Bolt and the Bolt Gear are further equipped with an Arduino Leonardo compatible Microchip Atmega32U4 MCU. The MCU can be used for robotics and other real-time applications. It can also be configured to run while the system is turned off and then turn on the computer based on trigger input.

  • Ultra-narrow DipDuino Arduino Compatible Board is a Perfect Breadboard Companion

    We previously wrote about a uChip DIP-sized Arduino Zero compatible board with 0.3″ spacing between the two rows of pins making it perfect for breadboards as it left four rows on each side of the breadboard.

    There’s now another similar option with the appropriately named DipDuino board equipped with a Microchip Atmega328P MCU compatible with Arduino Pro or Pro Mini boards.

  • Using Photoresistor From Raspberry PI To Detect Light

    Photoresistor (also known as photocell) is a Light Dependent Resistor (LDR). As the name suggests, this components act just like a resistor, changing its resistance in response to how much light is falling on it. Ususally, photoresistors have a very high resistance in near darkness and a very low resistance in bright ligh.

    This component is used to manage electronic or electric devices to answer light conditions enabling or disabling functions.

    Photoresistors are analogic components. So it can be used with microcontrollers having analogic inputs (like Arduino) to read light level.

    Unfortunately, Raspberry PI has only digital inputs (with threshold between High and Low being around 1V). This means that, without specific analogic-to-digital hardware, we’ll be able only to read if light is high or low.

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.
