  • New in Qt 5.11: improvements to the model/view APIs (part 1)

    The Qt model/view APIs are used throughout Qt — in Qt Widgets, in Qt Quick, as well as in other non-GUI code. As I tell my students when I deliver Qt trainings: mastering the usage of model/view classes and functions is mandatory knowledge, any non-trivial Qt application is going to be data-driven, with the data coming from a model class.

  • GNOME Is Removing the Ability to Launch Binary Apps from Nautilus

    Last year Nautilus lost the ability to show desktop icons — now GNOME developers plan to drop another familiar feature.

    According to a code commit on Gitlab the famous file manager is set to lose the ability to run binaries and launch apps directly.

    Or, to put it another way, you won’t be able to double-click on programs, scripts or apps to launch them using Nautilus.

  • Mageia Blog (English) : Issues with the Grand Update?

    This should not be needed, as 32-bit libraries should be able to co-exist on a 64 bit install, as they may be needed for third party applications.

    Bug 23016 has been reopened to study this a bit more. For now, we’re watching for reports, and giving you the workaround of uninstalling the 32 bit library.

    It’s not that 32-bit isn’t able to mix with 64-bit in all cases, just in some, where there are files in the lib package that should be in a different (non-arch specific) package. In these two cases, it’s the /usr/share/locale/ files are in both the 32 and 64 bit packages, with identical names and paths.

    The rpm package manager allows a file to be owned by more than one package, provided the attributes are identical, but it blocks updating with a new version, since it’s trying to update one of the packages, but until the other version is updated too, there is a conflict. We’re keeping a watch-out for these packaging errors.

    It’s possible that if you’ve used DNF to do the update, rather than urpmi, you won’t have this problem; as we gather more information, we’ll add it to roundups in the coming weeks.

    While all this Grand stuff has been happening, we’ve also been doing plenty of the usual things, including over 300 packages into Cauldron.

  • 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.

  • 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.
