  • Radeon Vulkan Driver Adds Option Of Rendering Less For ~30% Greater Performance - Phoronix

    If your current Vulkan-based Radeon Linux gaming performance isn't cutting it and a new GPU is out of your budget or you have been unable to find a desired GPU upgrade in stock, the Mesa RADV driver has added an option likely of interest to you... Well, at least moving forward with this feature being limited to RDNA2 GPUs for now.

    RADV as Mesa's Radeon Vulkan driver has added an option to allow Variable Rate Shading (VRS) via an environment variable override. This RADV addition is inspired by the likes of NVIDIA DLSS for trading rendering quality for better performance but in its current form is a "baby step" before being comparable to DLSS quality and functionality.

  • Bas Nieuwenhuizen: A First Foray into Rendering Less

    In RADV we just added an option to speed up rendering by rendering less pixels.

    These kinds of techniques have become more common over the past decade with techniques such as checkerboarding, TAA based upscaling and recently DLSS. Fundamentally all they do is trading off rendering quality for rendering cost and many of them include some amount of postprocessing to try to change the curve of that tradeoff. Most notably DLSS has been widly successful at that to the point many people claim it is barely a quality regression.

    Of course increasing GPU performance by up to 50% or so with barely any quality regression seems like must have and I think it would be pretty cool if we could have the same improvements on Linux. I think it has the potential to be a game changer, making games playable on APUs or playing with really high resolution or framerates on desktops.

    [...]

    VRS is by far the easiest thing to make work in almost all games. Most alternatives like checkerboarding, TAA and DLSS need modified render target size, significant shader fixups, or even a proprietary integration with games. Making changes that deeply is getting more complicated the more advanced the game is.

    If we want to reduce render resolution (which would be a key thing in e.g. checkerboarding or DLSS) it is very hard to confidently tie all resolution dependent things together. For example a big cost for some modern games is raytracing, but the information flow to the main render targets can be very hard to track automatically and hence such a thing would require a lot of investigation or a bunch of per game customizations.

  • Dota 2 version 7.29 is out with the new Dawnbreaker melee hero

    Valve has put out a major upgrade for their popular free to play MOBA with Dota 2 getting Dawnbreaker. This brand new hero is focused on melee, with a low-skill entry level so it should be suitable for a lot of players. You can see a dedicated hero page for Dawnbreaker here.

    "Dawnbreaker shines in the heart of battle, happily crushing enemies with her celestial hammer and healing nearby allies. She revels in hurling her hammer through multiple foes and then converging with it in a blazing wake, always waiting to tap her true cosmic power to fly to the aid of her teammates — eager to rout her enemies on the battlefield no matter where they are."

  • Grape times ahead with the release of Wine 6.6 noting plenty of fixes

    No wine-ing about the puns please. Jokes aside, the tasty compatibility tech that is Wine has a new development release available today with Wine 6.6.

    For newer readers and Linux users here's a refresher - Wine is a compatibility layer built for operating systems like Linux, macOS and BSD. The idea is to allow other platforms to run games and applications only built and supported for Windows. It's also part of what makes up Steam Play Proton. Once a year or so, a new stable release is made.

  • Rancher Platform Partner, Weka delivers Stateful Storage for Containers at Scale

    Containers rose to the mainstream primarily due to workload portability and immutability advantages. Kubernetes became the primary orchestration tool and was initially supporting stateless applications, commonly referred to as the cattle vs. pets approach. However, data-centric applications need stateful-ness while still leveraging the cattle vs. pet approach. Microservices, Containers, and Kubernetes are now moving mainstream as increasingly more stateful applications are adopting them.

  • Am I FLoCed? A New Site to Test Google's Invasive Experiment

    FLoC is a terrible idea that should not be implemented. Google’s experimentation with FLoC is also deeply flawed . We hope that this site raises awareness about where the future of Chrome seems to be heading, and why it shouldn't.

    FLoC takes most of your browsing history in Chrome, and analyzes it to assign you to a category or “cohort.” This identification is then sent to any website you visit that requests it, in essence telling them what kind of person Google thinks you are. For the time being, this ID changes every week, hence leaking new information about you as your browsing habits change. You can read a more detailed explanation here .

    Because this ID changes, you will want to visit https://amifloced.org often to see those changes.

  • The Brave browser basics: what it does, how it differs from rivals

    Boutique browsers try to scratch out a living by finding a niche underserved by the usual suspects. Brave is one of those browsers.

    Brave has gotten more attention than most alternate browsers, partly because a co-founder was one of those who kick-started Mozilla's Firefox, partly because of its very unusual — some say parasitical — business model.

  • 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.
