  • Using Modern CMake with Qt

    KDAB’s Kevin Funk presented Using Modern CMake with Qt at Qt Virtual Tech Con last month.

    Kevin reported that the Qt Company did a great job moderating the sessions at this event, and there was a lively Q&A at the end – Kevin had to pick from about 60 questions, so this is a hot topic.

    Now the event is over you can access the talks, including Kevin’s and the answers he had time for, and also Kevin’s slides, below this abstract.

  • Qt Design Studio 1.5 released

    We are happy to announce that the Qt Design Studio 1.5 is now available via the online and offline installers.

    Qt Design Studio 1.5 comes with a fully supported 3D editor which enables designing seamlessly integrated 2D and 3D UIs.

    We have taken the best concepts from Qt 3D Studio and ported them over to Design Studio. This is the first time we have a one unified designing tool that supports both 2D and 3D.

    To streamline collaboration between designers and developers Qt Design Studio can be used by both, designers and developers.

  • Qt 5.15 LTS Released

    I'm thrilled to announce that we've released Qt 5.15 LTS today. Qt 5.15 is going to be the last feature release of the Qt 5 series. As such, it is a bit special, and a lot of work has gone into preparations towards Qt 6, our next major release. While Qt 5.15 is supported as usual for all our users, Qt 5.15 will also provide long-term support for three years to all commercial license holders, including the new Qt for Small Business. Option for extended support is available after the three year support period.

  • Qt 5.15 Released With Graphics Improvements, Preparations Ahead Of Qt 6

    Qt 5.15 is a big LTS update and the last ahead of the Qt 6.0 release expected before the end of 2020. Qt 5.15 offers many graphics improvements, including the isolating its OpenGL renderer to a plug-in and experimental support for Vulkan with its Wayland platform code. Qt's embedded EGLFS layer has introduced support for Vulkan via the VK_KHR_display extension. Qt 5.15 additionally is bringing greater multi-threading within QImage scaling/conversion methods, support for rendering to multiple surfaces with Qt Multimedia, qmlformat to format QML code according to the QML coding guidelines, support for the nullish coalescing operator with QML, an updated Qt WebEngine, native file dialog support on Android, and countless other improvements for this open-source toolkit.

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.
