  • meg@akademy2017

    It's been a while since my last post over here. After being drained with a lot of work on the very first edition of QtCon Brasil, we all had to take some rest to recharge our batteries and get ready for some new crazinesses.

    This post is a short summary of the talk I presented at Akademy 2017, in the quite sunny Almería in Spain. Akademy is always a fascinating experience and it's actually like being at home, meeting old friends and getting recurrently astonished by all awesomeness coming out of KDE community Smile.

    My talk was about architecting Qt mobile applications (slides here | video here). The talk started with a brief report on our Qt mobile development experiences at IFBa in the last two years and then I explained how we've been using lean QML-based architectures and code generators to leverage the productivity and provide flexible and reusable solutions for Qt mobile applications.

  • 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.
