Submission + - HOWTO Make Mozilla Firefox Blazing Fast On Linux (linuxreviews.org)

Submitted by xiando
xiando writes: The Firefox web browser is, by default, much, much slower than it can be on Linux. There is, luckily, several ways to make it a whole lot faster by changing one or more configuration options that are not so easy to find or understand. Newly released Firefox 88 made it easier, though you can make older Firefox versions and Firefox LTS versions faster with some trickery.

Submission + - The Linux Mesa Vulkan Driver For AMD Will Get An Option Boosting Performance 30% (linuxreviews.org)

Submitted by xiando
xiando writes: Those who have the very latest Radeon RX 6000 series graphics cards from AMD will get the option of doing fewer fragment shader invocations per pixel rendered in Vulkan games when Mesa 21.1 is released come May. This can provide a huge performance-boost, or nearly none at all, depending on the game or workload. The new Mesa option requires variable rate shading support in hardware, so it is only for those who have a shiny new GPU from AMD.

Submitted by xiando
xiando writes: Signal Messenger LLC forgot to update the GitHub repository for the server-side part of their Signal messaging application for almost one year. Their last git commit to the Signal server was done on April 22nd, 2020 — until someone there remembered that they had promised to be a "open source" company a few hours ago. Signal just pushed a massive source code dump with all the code commits for Signal Server v3.21 to v5.48 to their public GitHub repository.

Submitted by xiando

Submission + - Almalinux 8.3 Is Released As A Stable RHEL Clone For Those Who Liked CentOS (linuxreviews.org)

Submitted by xiando
xiando writes: CentOS used to be the go-to alternative for those who wanted to use Red Hat Enterprise Linux (RHEL) without having to pay RedHat to use it. It was a almost 1:1 clone until RedHat took control of it and turned it into what is now a RHEL beta-version, not a stable RHEL release without the branding. Almalinux is one of several projects that have made their own RHEL forks in response. The first Almalinux version is now released.

Submission + - Linus Torvalds on Intel And AMDs New Approaches To Interrupt And Exception Handl (linuxreviews.org) 1

Submitted by xiando
xiando writes: AMD and Intel are both working on new standards for handling interrupts and exceptions on x86-64 processors. AMD is proposing a set of new "Supervisor Entry" extensions as a band-aid to the current interrupt descriptor table event handling system. Intel wants to throw that whole legacy system away and start over with a fundamentally different "Flexible Return and Event Delivery" (FRED) system. Linux-architect Linus Torvalds weighted in on the merits of both approaches a few weeks ago.
