  • Files 40.alpha: Creation timestamp & Wallpaper portal

    In my last post I’ve promised that the next one would have screenshots of new developments in the Files app, and it’s finally here!

    It took me longer than I expected back then. After the 3.38 release, I had to had to focus my time elsewhere: assisting and training local primary health care teams in managing and following up of the raising number of COVID-19 cases assigned to them. With this mission accomplished, in December I’ve picked up again on my GNOME contributions and have something to show you now.

  • GNOME Shell Merges Port Of Extensions App + Portal To GTK4 - Phoronix

    With GTK4 out and stabilizing well, more GNOME components are working to migrate to this updated toolkit as part of the GNOME 40 development cycle.

    The latest GTK4 porting work to be merged is GNOME Shell's extensions application and portal components being moved from GTK3 to GTK4.

  • GNOME 40 Will Finally Show File Creation Times Within Its File Manager - Phoronix

    Finally in 2021 with the GNOME 40 release is the ability of GNOME's Nautilus file manager to show and sort by file creation times...

    Going back more than a decade have been requests for being able to show timestamps for when files are created within the GNOME file manager or to be able to sort by file creation times in a folder rather than the last modified date. Initially that was blocked by the Linux kernel / file-systems exposing the information while in recent years that's been addressed and more time until it was implemented for GNOME.

  • Philip Withnall: Add extended information to GErrors in GLib 2.67.2

    Thanks to Krzesimir Nowak, a 17-year-old feature request in GLib has been implemented: it’s now possible to define GError domains which have extended information attached to their GErrors.

    You could now, for example, define a GError domain for text parser errors which includes context information about a parsing failure, such as the current line and character position. Or attach the filename of a file which was being read, to the GError informing of a read failure. Define an extended error domain using G_DEFINE_EXTENDED_ERROR(). The extended information is stored in a ‘private’ struct provided by you, similarly to how it’s implemented for GObjects with G_DEFINE_TYPE_WITH_PRIVATE().

  • 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.
