    The Ubuntu in the wild blog post ropes in the latest highlights about Ubuntu and Canonical around the world on a bi-weekly basis. It is a summary of all the things that made us feel proud to be part of this journey. What do you think of it?

  • TI10: The International for Dota 2 may not happen in Sweden now as it's not elite enough | GamingOnLinux

    The saga continues for the major upcoming Dota 2 tournament TI10: The International, with it now switching countries due to Sweden not accepting it.

    Delayed a while now thanks to the COVID-19 pandemic, Valve had been working closely with Stockholm Live and Visit Stockholm who seemed to repeatedly assure Valve it would qualify and get the same exemptions as "other elite sporting events there received". Sadly, that's not been the case.

  • Creating an app with QML: a heater control

    Last week I took the ICS course "Building an Embedded Application with Qt" and now it's time to put the gained knowledge into action. I decided to create an application to (simulate?) a heater control. Why? Because I have a very basic one at home, and I always dreamed of getting something better. So time to implement it.

  • Lisandro Damián Nicanor Pérez Meyer: Firsts steps into QML

    After years of using and maintaining Qt there was a piece of the SDK that I never got to use as a developer: QML. Thanks to ICS I've took the free (in the sense of cost) QML Programming — Fundamentals and Beyond.

    It consists of seven sessions, which can be easily done in a few days. I did them all in 4 days, but with enough time available you can do them even faster. Of course some previous knowledge of Qt comes handy.

  • Open Source 3D CAD Software for GNU Linux for 3D Printer Models

    OpenSCAD is a software for creating solid 3D CAD objects.

    It is free software and available for Linux/UNIX, MS Windows and Mac OS X.

    Unlike most free software for creating 3D models (such as the famous application Blender), OpenSCAD focuses on the CAD aspects rather than the artistic aspects of 3D modeling. Thus this might be the application you are looking for when you are planning to create 3D models of machine parts but probably not the tool for creating computer-animated movies.

    OpenSCAD is not an interactive modeler. Instead it is more like a 3D-compiler that reads a script file that describes the object and renders the 3D model from this script file (see examples below). This gives you, the
    designer, complete control over the modeling process and enables you to easily change any step in the modeling process or make designs that are defined by configurable parameters.

  • The Best of Both OSs | LINUX Unplugged 411

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.
