  • AMD Yellow Carp + Another Water Cooling Pump Head To Linux's Hardware Monitoring Code - Phoronix

    The Linux hardware monitoring "HWMON" subsystem for the 5.15 cycle is already seeing the AMD SB-RMI driver and AMD Cezanne Zen 3 APU temperature monitoring while there was also some last-minute additions around AMD next-gen "Yellow Carp" temperature reporting and separately support for another water cooling pump.

    As noted in the exciting news this weekend about Mario Limonciello joining AMD's Linux client CPU team, one of the tasks he's been working on has been enabling k10temp temperature reporting for Yellow Capr APUs. Yellow Carp is the Linux codename for what is looking like will be the next-gen AM Ryzen 6000 mobile series "Rembrandt" APUs.

  • Yet-To-Be-Released Intel "Bz" WiFi Chipset To Be Supported By Linux 5.15 - Phoronix

    While the Linux 5.15 merge window opening is imminent, merged today to net-next were the latest batch of wireless driver updates for this next kernel version. Notable to this batch of WiFi driver updates was the new Intel material.

    With this next kernel version the IWLWIFI driver used by current Intel WiFi chipsets now has support for discovery of hidden networks on the 6GHz band. Hidden 6GHz networks can now be discovered by the IWLWIFI driver when including the scan request direct SSIDs into the firmware scan request command. Previously there was no support in this Intel WiFi driver for being able to discover and connect to hidden 6GHz networks.

  • Linux 5.15 To Fix Regression In Its Floppy Disk Driver - Phoronix

    Near the beginning of the year was some rare work on Linux's floppy disk driver and -- a half-year later -- it was found out that not only do people with systems using floppy disks still move to newer kernels, but that work earlier in the year had regressed the Linux kernel's floppy disk handling. Now coming for Linux 5.15 is a fix.

    Since the changes to the floppy disk driver earlier in the year, the driver has continued to function but it silently and unintentionally altered some of the floppy disk handling code -- previously the kernel with the O_NDELAY flag would allow opening a floppy device even without a disk being inserted. The updated Linux kernel would yield an error if opening a floppy device without the media/disk inserted. Additionally, it broke opening up of floppy disks that are write-protected.

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.
