Open Source Operating Systems: FreeRTOS and Genode OS

  • Announcing FreeRTOS Kernel Version 10

    The number of connected IoT devices worldwide is in the billions and growing rapidly. Many of these edge devices – from fitness trackers to sensors to washing machines to automotive transmissions – use low-cost, low-powered microcontrollers with extremely limited memory and compute capability. For some IoT use cases, very predictable response times can also be critical (think: automotive). A standard operating system won’t work here: you need a real-time operating system (RTOS) that works in very constrained systems.

  • Release notes for the Genode OS Framework 17.11

    In contrast to most releases, which are focused on one or two major themes, the development during the release cycle of version 17.11 was almost entirely driven by the practical use of Genode as a day-to-day OS by the entire staff of Genode Labs. The basis of this endeavor is an evolving general-purpose system scenario - dubbed "sculpt" - that is planned as an official feature for the next release 18.02. The name "sculpt" hints at the approach to start with a minimalistic generic live system that can be interactively shaped into a desktop scenario by the user without any reboot. This is made possible by combining Genode's unique dynamic reconfiguration concept with the recently introduced package management, our custom GUI stack, and the many ready-to-use device-driver components that we developed over the past years.

  • Genode OS 17.11 Reworks Its "Nitpicker" GUI Server

    Genode is the open-source operating system framework designed for "highly secure" special-purpose operating systems from embedded platforms to desktops while subscribing to a Unix philosophy and going for an L4 micro-kernel approach. The Genode OS 17.11 represents another quarter's worth of changes.

    A lot of the work represented by Genode OS 17.11 is on beating the operating system platform into shape to be a day-to-day OS. Among the changes to find is its GUI stack being reworked, scroll-wheel emulation and pointer acceleration finally, other input handling improvements, all x86 micro-kernels now using the GRUB2 boot-loader, Nim programming language usage, and more.

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.
