KDE: Latte, Plasma Vision and GSoC

Filed under
KDE
  • Latte and "Flexible" settings...

    Following Latte and a "Shared Layouts" dream, today I am going to present you all the new settings pages for upcoming v0.9 and the approach used for them. In following screenshots you can find Basic and Advanced pages for docks and panels.

  • Plasma Vision

    The Plasma Vision got written a couple years ago, a short text saying what Plasma is and hopes to create and defines our approach to making a useful and productive work environment for your computer. Because of creative differences it was never promoted or used properly but in my quest to make KDE look as up to date in its presence on the web as it does on the desktop I’ve got the Plasma sprinters who are meeting in Valencia this week to agree to adding it to the KDE Plasma webpage.

  • Day 26

    I’m in the end of my semester at college, so I need to split my time with GSoC and my college tasks, so now I’m going slowly but on the next month I have my vacation and I’ll have all of my time dedicated to it.
    My menthors have helped me a lot so far, and I would like to say thanks for the patience, and say sorry for KDE for my initial project and for waste the first weeks on a thing that didn’t produce anything.

  • LabPlot getting prettier and also support for online datasets

    Hello everyone! I'm participating in Google Summer of Code for the second time. I'm working on KDE's LabPlot, just like last year. I'm very happy that I can work again with my former and current mentor Kristóf Fábián, and with Alexander Semke, an invaluable member of the LabPlot team, who is like a second mentor to me.

    [...]

    We had to create metadata files in order to record additional information about datasets, and also to divide them into categories and subcategories. We use a metadata data file which contains every category and subcategory and a list of datasets for every subcategory. Additionally there is a metadata file for every dataset containing various data about the dataset itself.

    In the "Datasets" section we highlight every dataset the metadata of which is locally available (in the labplot directory located in the user's home directory). When the user clicks on the "Clear cache" button every file is deleted from the above mentioned directory. The "Refresh" button provides the possibility to refresh the locally available metadata file, which contains the categories and subcategories.
    In order to make possible the import of datasets into LabPlot, and saving them into Spreadsheets I had to implement a helper class: DatasetHandler. This class processes a dataset's metadata file, configures the Spreadsheet into which the data will be loaded, downloads the dataset, processes it (based on the preferences present in the metadata file) then loads its content into the spreadsheet.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
