  • Open source Omega2 module gives way to a “Pro” SBC

    Onion’s “Omega2 Pro” update to its WiFi-enabled Omega2 board boosts RAM to 512MB and flash to 8GB and adds real-world USB and micro-USB ports. The Pro model runs OpenWrt on a 580MHz MIPS SoC.

    Boston-based Onion launched its IoT-oriented Omega computer-on-module on Kickstarter in early 2015 and returned the next year with an Omega2 model that switched the 400MHz Atheros AR9331 with a similarly MIPS-based, OpenWrt-driven 580MHz MediaTek MT7688 SoC that supported additional I/O. The open source module was also available in an Omega2 Plus model that added a microSD slot and doubled RAM and flash to 128MB and 32MB, respectively.

  • The Power of Zephyr RTOS

    The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures; it’s optimized for resource-constrained devices and built specifically with security in mind. To learn more, we talked with Thea Aldrich, Zephyr Project Evangelist and Developer Advocate, about the goals and growth of the project.

    The first question that comes to mind is what’s the need for Zephyr when the Linux kernel already exists? Aldrich explained that Zephyr is great in those cases where Linux is too big. “It’s a really small footprint, real-time operating system built with security and safety in mind for highly constrained environments,” she said.

  • A crash course in embedded Linux software deployment

    At ELC Europe, Mender.io’s Mirza Krak surveyed popular techniques for deploying embedded Linux software, including cross-dev strategies, IDEs, Yocto-OE package management, config utilities, network boot, and updating software.

    While many Embedded Linux Conference talks cover emerging technologies, some of the most useful are those that survey the embedded development tools and techniques that are already available. These summaries are not only useful for newcomers but can be a helpful reality check and a source for best practices for more experienced developers.

Onion Omega2 Pro open source

  • Onion Omega2 Pro open source, plug-and-play wireless Linux dev board

    A new tiny wireless Linux plug and play development board has been created by Onion in the form of the Onion Omega2 Pro. Offering a self-contained platform with the processor, memory, storage, and Wi-Fi radio baked into a single board. Watch the video below to learn more about this next generation Omega2 open source development board which is now available to preorder from $49 with free shipping throughout the United States and worldwide shipping available for just $6.

    “The Omega2 Pro is the next generation of our highly successful Omega2 and the most powerful IoT computer we’ve made yet. It is a standalone device – the processor, memory, gigabytes of storage, and Wi-Fi are all built-in, and it’s smaller than a breadboard. The storage is pre-loaded with the OpenWrt embedded Linux distro, so getting started is as easy as plugging in a Micro USB cable for power and taking a few minutes to go through the browser-based setup wizard.”

  • 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.
