  • Rust support hits linux-next

    Followers of the linux-next integration tree may have noticed a significant addition: initial support for writing device drivers in the Rust language. There is some documentation in Documentation/rust, while the code itself is in the rust top-level directory.

  • Initial Support For The Rust Language Lands In Linux-Next

    For a long while now Linux kernel developers have discusses the prospects of optionally allowing the Rust language to be used for new device drivers within the Linux kernel areas and other areas within the kernel for this language that prides itself on safety and performance. As the first baby step towards that dream, initial Rust support appeared this week in the Linux-Next tree.

  • NZXT Kraken Liquid Cooler Driver Under Review For The Linux Kernel - Phoronix

    While NZXT does not provide any official Linux software support for their products like their all-in-one liquid coolers, the open-source community for years has worked to fill that void thanks to reverse-engineering. The latest work when it comes to the NZXT Kraken AIO liquid coolers is a proposed HWMON driver for the mainline kernel.

  • RISC-V XIP Support Queued Ahead Of Linux 5.13 To "eXecute In Place" - Phoronix

    It looks like the Linux 5.13 kernel will be supporting an interesting RISC-V feature this spring.

    Queued up now in RISC-V's "for-next" branch as of this week is support for XIP, or eXecute In Place. RISC-V XIP allows for code to be executed directly from non-volatile storage that is directly addressable by the CPU. RISC-V XIP allows for executing code directly off CPU-addressable storage like QSPI NOR flash memory without first having to load it into system RAM.

  • Zink OpenGL-Over-Vulkan Still Has ~200 Patches To Land, More Performance Work - Phoronix

    Mike Blumenkrantz who has been working under contract for Valve as part of their Linux graphics driver initiatives has provided a fresh status report on Zink as the Mesa Gallium3D effort for implementing OpenGL APIs atop Vulkan.

    With supporting OpenGL 4 already and continuing to squeeze out more performance, Zink is on a solid footing but there still is even more work to land to further enhance this OpenGL-on-Vulkan implementation. Mike noted in the latest post that his work-in-progress "zink-wip" branch is down to around 200 patches left to clean-up and see through the review process for merging. Two hundred or so patches isn't bad at all when considering a month or so ago they were around 600 patches.

  • A More Accurate Update

    lavapipe is ramping up towards Vulkan 1.1 support, which will, other than being a great milestone and feat of software engineering, enable zink CI testing through GL 4.5

The Rust Programming Language Is Now One Step Closer To Entering

  • The Rust Programming Language Is Now One Step Closer To Entering The Mainline Linux Kernel

    The Linux kernel community has been discussing the possibility of using the Rust programming language to write new kernel device drivers since last summer. Initial Rust support has now landed in the Linux-Next tree. This does not guarantee that Rust will be supported or even allowed in the mainline kernel, but it does mean that there is now a fair chance that Rust will eventually be required to successfully compile a Linux kernel.

  • This Week in Programming: Rust (Likely) Headed for Linux Kernel’s Development Branch

    Rustaceans’ dreams of Rust’s inclusion in the Linux kernel are one tiny, ever so slight step closer to becoming a reality, with this week’s “intentionally bare-bones” inclusion in Linux-next, the development branch of the Linux kernel. When last we looked, Rust was yet a mere twinkle in the eyes of those hoping to use the language in Linux kernel development, with Linux creator Linus Torvalds signaling his approval, and now that twinkle has brightened up just a bit more.

    Curb your enthusiasm, however, as this remains a rather tentative first step of many necessary steps before Rust fully lands in the Linux kernel.

  • 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.
