  • Wayland support (and more) for Emacs

    Jeffrey Walsh started off his 2021 presentation with a statement that, while 2020 was not the greatest year ever, there were still some good things that happened; one of those was the Emacs 27.1 release. This major update brought a number of welcome new features, but also led to yet another discussion on the future of Emacs. With that starting point, Walsh launched into a fast-moving look at the history of Emacs, why users still care about it, what changes are coming, and (especially) what was involved in moving Emacs away from the X window system and making it work with the Wayland compositor.
    There were a number of good things to be found in the 27.1 release, which was a "huge jump" in functionality. Perhaps at the top of the list is support for the HarfBuzz library, which brings improved text-rendering support in multiple languages — and the support for color emoji that no self-respecting 2020s application can be without. Portable dumping was finally added, leading to faster startup and less system-dependent code. Emacs also now supports a tab-based interface, something that "had been asked-for forever", Walsh said.

  • OBS Studio Merges Its EGL-Wayland Code To Natively Support Wayland

    OBS Studio, the cross-platform open-source solution for live streaming and screen recording, has landed the last major piece of its effort to natively support Wayland.

    The EGL/Wayland renderer code that has been under review for about one year was finally merged into OBS Studio. This follows earlier work like EGL on X11 support and other preparations while now at last the EGL-Wayland code has been merged to offer native Wayland support via the new windowing system code path.

  • 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.
