Embedded solution developers are often attracted to the “free” aspect of Linux and choose the RYO development route. However, an unsupported distribution might leave developers vulner­able to a wide range of hidden costs, risks, and time-consuming activities. This paper explores the top questions and myths about unsupported Linux for embedded applications.

[...]

As an attractive development platform, unsupported Linux distributions tend to capture the attention of organizations through the concept of reduced investment and no upfront cost. When evaluating the associated costs, businesses should strategically weigh the long-term vs short-terms costs and re­quirements of unsupported Linux.

  • Barix Unveils Linux-Based Barionet Control Automation and IoT Devices

    The new devices, which debuted at ISE 2019, “combine the power and flexibility of the universal, programmable Barionet platform with the simplicity of Lua programming and a cloud-based code deployment solution,” according to the Barix press release.

    Barix’s latest models support the Lua scripting language, “making customization of the devices’ behavior easier than ever before,” according to the company announcement.

  • How to run DOS on a Raspberry Pi

    Please note: this tutorial is not for beginners. This tutorial requires the use of Raspian terminal commands which are text-based, so you’ll at least need to have basic Linux knowledge. You can’t run actual MS-DOS on the Raspberry Pi as is, instead you will be running DOS via an emulator. By using a combination of QEMU PC emulator and FreeDOS, you can play classic DOS games and run other DOS programs on the Raspberry Pi. Once you’ve set up QEMU as the virtual machine and installed FreeDOS, you can run DOS programs and games on the Raspberry Pi.

    At the moment, FreeDOS is the only DOS program that will allow you to run programs and games. The reason that you can’t install FreeDOS directly on the Raspberry Pi is because of the CPU architecture. Like any DOS, FreeDOS requires an Intel x86 CPU and a BIOS to provide basic runtime services. The Raspberry Pi operates using a completely different architecture, using an ARM CPU, which is not binary compatible with the Intel CPU and does not include a BIOS. Therefore, FreeDOS can’t run on the Raspberry Pi natively and instead must be used via an emulator.

  • 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.
