  • Mesa 20.1.2 Release Led By Radeon Driver Fixes

    While Mesa 20.2 is the exciting development version in the works for release next quarter, those of you on the current Mesa 20.1 series now have the second point release available.

    Mesa 20.1.2 is out with two weeks worth of fixes for this stable series. This time around the Radeon Vulkan (RADV) and OpenGL (RadeonSI) driver changes make up a majority of the changes.

  • They want to be small, they want to be big: thoughts on code reviews and the power of patch series

    Code reviews are a central fact of life in software development. It's important to do them well, and developer quality of life depends on a good review workflow.

    Unfortunately, code reviews also appear to be a difficult problem. Many projects are bottlenecked by code reviews, in that reviewers are hard to find and progress gets slowed down by having to wait a long time for reviews.

    The "solution" that I've often seen applied in practice is to have lower quality code reviews. Reviewers don't attempt to gain a proper understanding of a change, so reviews become shallower and therefore easier. This is convenient on the surface, but more likely to allow bad code to go through: a subtle corner case that isn't covered by tests (yet?) may be missed, there may be a misunderstanding of a relevant underlying spec, a bad design decision slips through, and so on. This is bound to cause pains later on.

  • Mike Blumenkrantz: When Maths Get Weird

    During shader compilation, GLSL gets serialized into SSA form, which is what ntv operates on when translating it into SPIR-V. An ALU in the context of Zink (specifically ntv) is an algebraic operation which takes a varying number of inputs and generates an output. This is represented in NIR by a struct, nir_alu_instr, which contains the operation type, the inputs, and the output.

    When writing GLSL, there’s the general assumption that writing something like 1 + 2 will yield 3, but this is contingent on the driver being able to correctly compile the NIR form of the shader into instructions that the physical hardware runs in order to get that result. In Zink, there’s the need to translate all these NIR instructions into SPIR-V, which is sometimes made trickier by both different semantics between similar GLSL and SPIR-V operations as well as aggressive NIR optimizations.

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.
