  • Arduino Create Platform Can Now Program Linux Internet of Things Devices

    The official Arduino development team has today revealed at the Embedded Linux Conference 2018 expansion of a number of architectures supported by its Arduino Create platform for the development of Internet of Things applications. The latest release allows Arduino Create users can manage and program a wide range of popular Linux single-board computers such as the awesome Raspberry Pi which has today received a new addition to its range in the form of the Raspberry Pi 3+, AAEON UP² and BeagleBone as if they were regular Arduino development boards.

  • An introduction to RISC-V

    LWN has covered the open RISC-V ("risk five") processor architecture before, most recently in this article. As the ecosystem and tools around RISC-V have started coming together, a more detailed look is in order. In a series of two articles, I will look at what RISC-V is and follow up with an article on how we can now port Linux distributions to run on it.

    The words "Free and Open RISC Instruction Set Architecture" are emblazoned across the web site of the RISC-V Foundation along with the logos of some possibly surprising companies: Google, hard disk manufacturer Western Digital, and notable ARM licensees Samsung and NVIDIA. An instruction set architecture (ISA) is a specification for the instructions or machine code that you feed to a processor and how you encode those instructions into a binary form, along with many other precise details about how a family of processors works. Modern ISAs are huge and complex specifications. Perhaps the most famous ISA is Intel's x86 — that specification runs to ten volumes.

    More importantly, ISAs are covered by aggressive copyright, patent, and trademark rules. Want to independently implement an x86-compatible processor? Almost certainly you simply cannot do that without making arrangements with Intel — something the company rarely does. Want to create your own ARM processor? You will need to pay licensing fees to Arm Holdings up front and again for every core you ship.

    In contrast, open ISAs, of which RISC-V is only one of the newest, have permissive licenses. RISC-V's specifications, covering user-space instructions and the privileged instructions are licensed under a Creative Commons license (CC BY 4.0). Furthermore, researchers have determined that all RISC-V instructions have prior art and are now patent-free. (Note this is different from saying that implementations will be open or patent-free — almost certainly the highest end chips will be closed and implementations patented). There are also several "cores" — code that compiles to Verilog and can be programmed into an FPGA or (with a great deal more effort) made into a custom chip — licensed under the three-clause BSD.

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.
