  • GNOME's Window Rendering Culling Was Broken Leading To Wasted Performance

    It turns out for the GNOME 3.34 and 3.36 series, Mutter's window rendering culling code was broken and that led to extra rendering of windows not even visible... A fix is in the works and can lead to the performance doubling or more.

    As part of wanting to improve the GNOME performance at 4K with Intel graphics, Canonical's Daniel van Vugt has been profiling various desktop issues and looking to address them for GNOME 3.38 / Ubuntu 20.10.

    One of his recent discoveries is that the Mutter windows culling code in general was broken and given the greater number of pixels to handle at 4K becomes more pronounced there. Even windows not being presented at all were not being vulled and that leads to a huge waste especially at high resolutions. When dragging a small terminal window over eight maximized window terminals, fixing the issue led to a frame rate from 30 to 60 FPS. Or when running a maximized glxgears window over eight maximized terminal windows, the frame-rate went from 15 to 60 FPS.

  • Linux Plumbers Conference: Kernel Dependability and Assurance Microconference Accepted into 2020 Linux Plumbers Conference

    We are pleased to announce that the Kernel Dependability & Assurance Microconference has been accepted into the 2020 Linux Plumbers Conference!

    Linux is now being used in applications that are going to require a high degree of confidence that the kernel is going to behave as expected. Some of the key areas we’re seeing Linux now start to be used are in medical devices, civil infrastructure, caregiving robots, automotives, etc. This brings up a number of concerns that must be addressed. What sort of uptime can we count on? Should safety analysis be reevaluated after a bug fix has been made? Are all the system requirements being satisfied by Linux? What tooling is there to solve these questions?

  • LibreOffice GSoC Week 3 Report

    After a long time(work), I proudly present you the first prototype of the Additions dialog. For 3 weeks I have been dealing with both the extension manager’s code and the connection of UI components to the project. In addition, I worked for the API, which will serve as a bridge between the site where the extensions are hosted and the project. For example, I prepared a sample API response and define parameters which is essential part to call GET request.

  • 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.
