  • Google Trumpets The Success Of Their Chrome "RenderingNG" Performance Initiative - Phoronix

    For the better part of the past decade Google has been pursuing performance improvements to their Chrome/Chromium web browser as the "RenderingNG" initiative to provide faster web page performance, lower memory consumption, and better battery life. This current work is finally wrapping up in 2021 to great success.

    In a new blog post on Wednesday, Google is talking up "150% or more faster graphics rendering" compared to older versions of Chrome along with a "6x reduction in GPU driver crashes on problematic hardware". Or even with the new Chrome 93 to 94 transition alone they are proclaiming up to 8% more responsive web pages, up to 1400 years of CPU time per day saved, and up to 0.5% improved battery life.

  • DIY compile chromium

    The saga has been going on for a couple of weeks. I am compiling chromium in EasyOS. Each build takes 13 hours, running on a Lenovo PC with Intel 8th gen. i3 CPU, 32GB RAM, swap partition on internal SSD, the source on an external USB3 SSD.

    [...]

    I don't recommend installing in a container, as video playing is choppy, with audio out of sync. I think that the other chromium SFS, the official build, does play OK in a container -- from memory -- but as it runs with the "--no-sandbox" option you get that warning message.
    Note to pup and *dog users. SFSs in EasyOS are a bit different, the SFS won't work for you, as-is. EasyOS has glibc 2.33, and if your pup has an older glibc then it probably won't work. Also, you would need to open it up and modify /usr/bin/chromium script so that it runs as 'spot'. There is folder '.control' that you won't need.
    Very ambivalent about compiling chromium. So many issues, so many patches. Think maybe should just use the official build from Google. I read some comments, some other distro maintainers are thinking the same thing, mostly because of the API keys problem.

  • DMA-BUF Support In WebRTC

    It will be almost three years since we landed initial support for screensharing on Wayland with the use of PipeWire in the WebRTC project. This enabled screensharing support in both major Linux browsers. Last year I implemented support for window sharing, added support for PipeWire 0.3 and added support for DMA-BUF and MemFD buffer types. Problem was, as it turned out, the DMA-BUF support was not implemented in a correct way.

    The original implementation was using mmap() to get the buffer content. This worked correctly for current Intel GPUs, but was terrifically slow on e.g. AMD GPUs. Proper solution is to use OpenGL context to get the content from buffer. However, there were many implementations using mmap() already, including WebRTC and we needed a way how to properly communicate between the server and the client that when the client advertises DMA-BUF support, it means it doesn’t use mmap() and goes through OpenGL context instead.

  • Chrome 96 To Feature Improved WebRTC Code, Better Wayland Screensharing

    Jan Grulich has been working on a new DMA-BUF implementation within the WebRTC code as the original DMA-BUF buffer sharing code was found to be inadequate. In particular, the original DMA-BUF mmap-based approach was found to perform very slow with the AMD Radeon Linux graphics driver and instead this new implementation allows using an OpenGL context to get the context from the buffer. Long story short, after a lot of work that new WebRTC DMA-BUF code is now good to go.

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.
