  • [LibreOffice Writer] Week #5 - GSoC Weekly Report - 100 Paper Cuts

    So, the last decision is: get rid of writer-images. Convert them into drawing objects ,but also implement the writer-images services/attributes to drawing-images. Since there are lots of things to do and we have only 5 week left after the first evaluations week, I prefer to work on this issue after GSoC with a huge free time. Also, I want to work on other bugs too, not only one.

  • An eventful week — Kalendar week 5 (GSoC 2021)

    Last week’s MR turned into this week’s MR, and it just kept growing and growing and growing. I know I’m a mentor’s nightmare and I’m sorry Carl, I know it was a lot of changes to review…

    The good news is that it was all worth it, because there have been lots of changes this week — small and big. Even better, you’ll finally be able to find the changes I went through in last week’s post on Kalendar’s master branch.

    Let’s dive into the new stuff!

    Editing the event editor

    If you’ve been following these posts, you will have seen the event editor: an overlay sheet that lets you edit the details about an event down to a tee. Well, that overlay sheet is no more. It made sense when we had a few fields to fill, but as the capabilities of the event editor started to grow, it pretty quickly started to feel pretty cramped.

    On the desktop, we now use the incredible power of windows to create a detached event editor window. So now you not only have plenty of space to punch in your next visit to your grandma’s, but you can also move it around and resize it. How revolutionary.

  • Gtk-rs Is Pretty Neat

    Fortunately, we can look at the Gtk4 bindings for help, I found layout_manager.rs to be a useful example – one gotcha to watch out for is vfuncs, especially signals, as they don’t necessarily have a default implementation

    Unfortunatly gtk-rs doesn’t have any magic for generating introspection data (yet?) so we follow rsvg’s example and manually build C-ABI wrappers along with a hand-written header to use with g-ir-scanner – handle.rs is a useful resource when doing this.

  • Hackathon organised by IIT Madras encourages citizens to find solutions using IoT Sensor Board | Technology

    Citizens across the country can now participate in solving India-specific problems of societal interest using IoT Sensor Board through a national hackathon called 'SAMVEDAN 2021 - Sensing Solutions for Bharat', a statement said on Saturday.

  • 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.
