  • NVIDIA Contributing Tegra NVDEC Support To Linux 5.16 - Phoronix

    The Tegra DRM driver changes were sent out on Friday of the new material destined for Linux 5.16. Notable this time around is NVIDIA's NVDEC driver being included.

    After going through rounds of public code review, the Tegra DRM driver updates for Linux 5.16 include the introduction of the NVDEC driver for accelerated video decoding. This open-source video decode engine work is for the Tegra X1 (Tegra210) and newer, including the Tegra X2 and Xavier SoCs at this time.

  • Linux 5.15-rc5 x86 Changes Aim To Fix "Yet Another Hardware Trainwreck" - Phoronix

    Sent in this morning were an urgent set of x86 updates for the Linux 5.15-rc5 kernel due out later today.

    With this x86/urgent pull request is "Yet another attempt at fixing the never-ending saga of botched x86 timers, this time because some incredibly smart hardware decides to turn off the HPET timer in a low power state - who cares if the OS is relying on it..."

Linux Developers Push Urgent Patches...

  • Linux Developers Push Urgent Patches To Fix 'Yet Another Hardware Trainwreck' | HotHardware

    Accurate timers are critical to the function of the low-level parts of the underlying code that drives the user-facing software we actually use in our daily lives. Fortunately, x86-64 PCs include numerous timers. Actually selecting which of those timers to use in a given scenario, however, can be a headache due to bugs, design flaws or implementation issues.

    The preferred timer on most modern machines should be the High-Precision Event Timer, or HPET. Sadly, that's not always the case on recent Intel hardware. Back in 2019, Linux started disabling the HPET on Coffee Lake and Ice Lake-based Intel platforms, owing to problems with the timers' accuracy when the system enters the PC10 low-power state (part of the "S0ix" states introduced with Haswell. Remember when companies started selling "Haswell-ready" power supplies?)

The latest Linux release candidate...

  • The latest Linux release candidate helps circumvent a hardware disaster | TechRadar

    An urgent set of patches for the latest release candidate (RC) of the under-development Linux v5.15 kernel reportedly helped the popular open source kernel avert what’s described as a “hardware trainwreck”.

    Phoronix caught hold of last minute urgent updates sent hours before Linus Torvalds, the kernel’s principle developer, was to put out the fifth RC of the upcoming kernel.

    The patch was added by longtime kernel developer Thomas Gleixner who described it as “yet another attempt at fixing the never-ending saga of botched x86 timers...”

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.
