  • Linux 5.10 Adding Support For AMD Zen 3 CPU Temperature Monitoring

    The next version of the Linux kernel will allow monitoring temperatures of the upcoming AMD Zen 3 processors.

    While CPU temperature monitoring support may seem mundane and not newsworthy, what makes this Zen 3 support genuinely interesting is that it's coming pre-launch... This is the first time in the AMD Zen era we are seeing CPU temperature reporting added to the Linux driver pre-launch. Not only is it coming ahead of the CPUs hitting retail channels but the support was added by AMD engineers.

  • FFmpeg Now Supports GPU Inference With Intel's OpenVINO

    Earlier this summer Intel engineers added an OpenVINO back-end to the FFmpeg multimedia framework. OpenVINO as a toolkit for optimized neural network performance on Intel hardware was added to FFmpeg for the same reasons there is TensorFlow and others also supported -- support for DNN-based video filters and other deep learning processing.

  • Intel SGX Enclave Support Sent Out For Linux A 38th Time

    For years now Intel Linux developers have been working on getting their Software Guard Extensions (SGX) support and new SGX Enclave driver upstreamed into the kernel. SGX has been around since Skylake but security concerns and other technical reasons have held up this "SGX Foundations" support from being mainlined. There has also been an apparent lack of enthusiasm by non-Intel upstream kernel developers in SGX. This past week saw the 38th revision to the patches in their quest to upstreaming this support for handling the Memory Encryption Engine (MEE) and relates SGX infrastructure.

    [...]

    The Intel SGX foundations v38 code can be found via the kernel mailing list. The Linux 5.10 merge window is opening up next month but remains to be seen if it will be queued for this next cycle or further dragged out into 2021.

  • Intel SGX foundations
    Intel(R) SGX is a set of CPU instructions that can be used by applications
    to set aside private regions of code and data. The code outside the enclave
    is disallowed to access the memory inside the enclave by the CPU access
    control.
    
    There is a new hardware unit in the processor called Memory Encryption
    Engine (MEE) starting from the Skylake microacrhitecture. BIOS can define
    one or many MEE regions that can hold enclave data by configuring them with
    PRMRR registers.
    
    The MEE automatically encrypts the data leaving the processor package to
    the MEE regions. The data is encrypted using a random key whose life-time
    is exactly one power cycle.
    
    The current implementation requires that the firmware sets
    IA32_SGXLEPUBKEYHASH* MSRs as writable so that ultimately the kernel can
    decide what enclaves it wants run. The implementation does not create
    any bottlenecks to support read-only MSRs later on.
    
    You can tell if your CPU supports SGX by looking into /proc/cpuinfo:
    
    	cat /proc/cpuinfo  | grep sgx

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.
