  • Free RPG Day: Create maps for your Dungeons & Dragons game with Mipui | Opensource.com

    It's Free RPG Day again, and there's no better to play a free roleplaying game than with free and open source software. In this digital era of pen-and-paper gaming, it's still relatively unusual for adventures to include digital maps. In fact, it's also unusual for paper adventures to include maps that are sized correctly for miniatures, and many that do have colourful and richly textured maps that look great in a glossy book but look murky when photocopied and enlarged for the tabletop. Long story short: a tabletop gamer is often in need of a quick and convenient way to produce maps. Mipui is an open source web app that enables you to create grid-based maps for role-playing games, and it works great for virtual and physical tabletops alike.

  • Hackaday Podcast 174: Breaking Into The Nest, The Cheapest 3D Printer, A Spy In Your HDMI, And AI All Over The Place

    Fresh from vacation, Editor-in-Chief Elliot Williams makes his triumphant return to the Hackaday Podcast! He’s joined this week by Managing Editor Tom Nardi, who’s just happy he didn’t have to do the whole thing by himself again. In this episode we’ll talk about tackling BGA components in your custom PCBs, a particularly well executed hack against Google’s Nest Hub, and why you probably don’t really want the world’s cheapest 3D printer. We’ll also take a look at an incredible project to turn the Nokia 1680 into a Linux-powered handheld computer, a first of its kind HDMI firewall, and a robot that’s pretty good at making tacos. Listeners who are into artificial intelligence will be in for quite a treat as well, as is anyone who dreams of elevating the lowly automotive alternator to a more prominent position in the hacker world.

  • 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.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think).
