  • What is RISC-V?

    Almost all new IoT/edge devices that can run Linux use either the x86 architecture (mostly Intel, some AMD) or Arm, which is licensed by vendors like Qualcomm, Nvidia, NXP, Huawei, and Samsung. Arm is ubiquitous in smartphones and dominant among open-spec, community-backed SBCs such as the Raspberry Pi (see What is an SBC?). When referring to such boards, I prefer to use the term open-spec. Even if a project is scrupulous in meeting open source requirements, there is always at least one component that is proprietary: the processor.


  • NXP’s Ultra-Wideband (UWB) evaluation kits work with Apple U1 chip - CNX Software

Out today is version 2.4 of Mir with more features and fixes.

    Mir 2.4 adds a new driver-quirks option for its GBM-KMS back-end, --enable-key-repeat is now respected with Mir's Wayland code, timestamps are now handled under Wayland for frame done events, and the Mir X11 platform has also seen a number of improvements too. On the X11 front, Mir 2.4 now adds the hostname to the window title when remoting via X-forwarding, the X11 platform code has finally been ported from Xlib to XCB, support for resizing Mir-on-X11 windows, and also a number of X11 platform fixes.

  • 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.
