  • What is embedded Linux? Part I

    The above is an excerpt from Linus Torvalds’ original announcement of what came to be known worldwide as the Linux operating system (OS), dated August 1991. In hindsight, it is inconceivably modest now that we are in a much better position to appreciate the full revolutionary extent of his post. Today, more than 96.4% of the top 1 million server applications run on Linux [2]. Across public clouds, 90% of the workloads use Linux as their OS, with Ubuntu being the most popular Linux distro [3], [4]. Despite debuting as a general-purpose operating system (GPOS) for x86-based hardware, Linux moved beyond web servers and has seen widespread adoption for embedded systems ever since.

    This two-part blog series aims to provide the reader with a broad overview of topics spanning the world of Linux, embedded systems and the Internet of Things (IoT) in general. In part I of this blog series, we’ll start by taking a look at the embedded ecosystem, followed by an explanation of Linux’s role in it, and will conclude by explaining the rationale behind the OS growing popularity in embedded systems. In part II, we’ll focus on the most pressing challenges facing enterprises today within the embedded space. Let’s get started.

  • A 100 Mhz 6502 CPU | Blathering – CubicleNate's Techpad

    I am not an expert in… well… anything, but I am I am continually impressed by the work done by so many in the world, especially in the “retro tech” world. I read this post by Jürgen Müller on his personal site concerning his project of an FPGA based 100 Mhz 6502 CPU. Just reading the title, my thoughts went in numerous directions about the amazing possibilities

    Using FPGA to emulate vintage computer hardware, let along the 6502 CPU is not new but packaging it on a small board the size of a 40-pin dual inline package hasn’t been done before. The work of Jürgen Müller is an extension on the work of others. This project is packaged on a Spartan-6 FPGA with 64 Kbyte on-chip RAM, mounted on a small circuit board and coined the 65F02. It has the ability to access the external bus on the host system with the correct timing. The FPGA CPU core runs at 100 MHZ where the idea is to make this a “universal” accelerator for 6502 and 65C02 based computers that only requires plugging it into the CPU socket.

    This won’t work with all computers based on this architecture and there are some limitations. More complex systems like the Commodore 64 with bank switching also provide some challenges as the extended memory cannot be run at the accelerated rate. The expansion boards and bank switching need to be known and emulated by the 65F02. While it makes an effort to detect and access the time-critical peripheral devices there are likely to be incompatible software and and-on hardware. Also, not all software should be accelerated, like video games as they are tied closely to the original systems timings.

  • OWC launches Mercury Elite Pro mini USB-C storage drive for Mac, Windows, and Linux [Ed: There's NO connection to "LINUX" (as usual) and I'm guessing that it's a sponsored 'article' that Brian Fagioli is being compelled to make, discrediting BetaNews and himself ahead of Black Friday SPAM festival. Meanwhile, CNX is selling out again, shilling Microsoft malware as as "Sponsored Post". Not the first time; even worse sellout than previous similar examples from the same site...]

    Today, OWC launches its latest portable storage drive. Called "Mercury Elite Pro mini," this elegant storage solution has a USB-C port and ships with both a USB-C cable and USB-A adapter. In other words, it can be used with any modern computer -- whether it has a USB Type-C port or not. In fact, the company says the drive is compatible with Mac, Windows, and Linux-based operating systems, including Android and Chrome OS.

  • AMD Ryzen V1000/R1000 Mini-ITX board is made for game arcades, slot machines - CNX Software

    Axiomtek GMB140 is a compact Mini-ITX motherboard powered by AMD Ryzen Embedded V1000/R1000 processor and mostly designed for gaming applications, as well as medical imaging, interactive kiosks, control rooms, and video surveillance.

    But when we’re not talking about your kids playing games at home here, but instead slot machines, arcade systems, and electronic gaming machines (EGM) powered by the GMB140 board with a PCIe interface for gaming I/O modules, and optional support for a 9-bit serial port for the SAS 6.02 protocol.

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.
