  • CMake-Based Qt Creator Snapshots

    About a year ago we started porting the build system that we use for building Qt Creator itself from qmake to CMake. Nowadays we are in the state that many Qt Creator developers use CMake for building Qt Creator for their daily work, but the official packages are still based on the qmake build.

  • Week #6 Progress [MyPaint Engine]

    Last week my prime focus was to add more and more settings in the preset editor and so as to make mypaint brushes a bit more customizable. I used KisCurveOptionWidget class which Krita already has and modified it so that it can accomodate the settings and dynamic mypaint brush options. This went on to become a lot more complicated than I anticipated. Although, it works fine there are still a lot of bugs and finishing required to mark this as complete.

  • Stack Abuse: What's New in Tensorflow 2.0?

    If you are a Machine Learning Engineer, Data Scientist, or a hobbyist developing Machine Learning Models from time to time just for fun, then it is very likely that you are familiar with Tensorflow.

    Tensorflow is an open-source and a free framework developed by Google Brain Team written in Python, C++, and CUDA. It is used to develop, test, and deploy Machine Learning models.

    Initially, Tensoflow did not have full support for multiple platforms and programming languages, and it was not very fast and efficient for training Machine Learning models, but with time and after a few updates, Tensorflow is now considered as a go-to framework for developing, training and deploying machine learning models.

  • 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.
