  • Inspired by the likes of Cube World, open source RPG Veloren has the biggest update yet | GamingOnLinux

    Currently in development and not yet considered a full game but still very impressive anyway, Veloren is a free and open source multiplayer voxel RPG. Inspired by the likes of Cube World, Legend of Zelda: Breath of the Wild, Dwarf Fortress and Minecraft it's a very exciting project to be following. Written in the popular Rust programming language it fully supports Linux, macOS and Windows.

    This latest release is the biggest yet, with overhauls to various parts of the game as well as introducing plenty of new features to keep players busy.

    The full source code is up on GitLab.

  • Godot Engine - Godot's 2D engine gets several improvements for upcoming 4.0

    While the focus of Godot 4.0 Vulkan rewrite has largely been enhancements to the 3D engine, the 2D side will also see several improvements.

    Improved Performance

    Thanks to Vulkan (which has a much lower draw-call cost than OpenGL), 2D itself in Godot 4.0 will see a speedup for free. But that's not the only reason, many internal improvements and optimizations also contribute to a smoother experience. Changes in memory allocation strategy and internal simplification in draw call logic make it much more efficient to manually call thousands of draw() functions from a node's _draw() callback. Many of these improvements will also accelerate GLES3 and GLES2 back-ends.

    Improved 2D lighting

    Godot 3.x supported 2D lighting, but this did not happen without several constraints. The main one was performance due to every light being rendered in a separate draw pass. This is no longer a problem in 4.0, as all lights are drawn in a single pass.

  • Auditing the CRLs in CRLite • Insufficient.Coffee

    Since Firefox Nightly is now using CRLite to determine if enrolled websites’ certificates are revoked, it’s useful to dig into the data to answer why a given certificate issuer gets enrolled or not.

    Ultimately this is a matter of whether the CRLs for a given issuer are available to CRLite, and are valid, but the Internet is a messy place, and sometimes things don’t work as planned. If an issuing CA is not enrolled in CRLite, the Mozilla infrastructure emits enough information to figure out what went wrong.

  • How to install FreeBSD on Raspberry Pi? (step-by-step guide)

    FreeBSD is an original operating system you can install on Raspberry Pi to experiment a bit outside Linux. But the process is not always easy if you are used to working on Debian-like systems.

    Today, we’ll see how to install it on a Raspberry Pi, to configure it and use it like almost like any other operating system.

  • October/November in KDE Itinerary

    A lot has happened around KDE Itinerary in the past two months again, since the last summary blog. All components will be part of the KDE release service starting with the 20.12 series, we got a new backend server for the station maps, arrival and departure platforms are now properly identified, and much more.

    [...]

    The biggest news behind the scenes is that the new backend for maps.kde.org is now finally live! This gives us up-to-date OSM data for the train station maps, with a lot more detail and various precision loss issues fixed. Most visible is probably that we now also see platform section labels and ticket machines, as well as almost all geometry reassembly glitches being fixed now.

    This work not only helps KDE Itinerary, but also the primary user of this system, Marble. A big thank you to the sysadmin team for making that happen!

    A number of things are happening around KDE’s Android infrastructure as well, which KDE Itinerary relies upon. See the dedicated post on that.

  • About Asus Chromebox – Linux Hint

    In partnership with Google, Asus joined the bandwagon in reinventing desktops into smaller forms and integrating Chrome OS into it, breathing new life to the declining traditional forms. Asus Chromebox is an elegantly-styled, lightweight, compact, and versatile desktop. It’s highly favored by users who only need the basics of a desktop computer, such as web browsing, video streaming, and simple file processing. Furthermore, it has full support for Android apps on Google play. The price tag is also pocket-friendly, especially if you are content with lower-end models. There is also no need to install anti-virus software as the built-in security with Chrome OS automatically installs updates and fixes, keeping it safe from some malware and viruses. Although Asus Chromebox has not been the first in the market, it has been making waves since its introduction in 2014.

    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.
