  • Google's FS-VERITY File Authentication Called For Inclusion In Linux 5.4 Kernel

    Linux kernel engineer Eric Biggers of Google has sent in a pull request adding FS-VERITY support to the Linux 5.4 but it remains to be seen if Linus Torvalds is content with pulling the code at this stage.

    FS-VERITY is the code Google has been working on for a while now in the context of Android. The focus is on providing transparent integrity/authenticity support for read-only files on an otherwise writable file-system. See this presentation to learn more on this file-based authenticity protection.

  • Linux 5.4 Brings Working Temperature Reporting For AMD Ryzen 3000 Series CPUs

    Due to a combination of poor timing and an oversight at AMD, the CPU temperature reporting under Linux for the Ryzen 3000 series processors isn't in order until this new Linux 5.4 cycle. Back at the Ryzen 3000 series launch event I was told everything was "all good" from the Linux support perspective for thermal monitoring, after having been closely following the situation for past Zen CPUs and ended up myself adding the Linux CPU temperature monitoring support for Threadripper 2 among other hudles in the past. That all-good though just ended up meaning that there is no Tcontrol offset needed for these new CPUs, which is great news no longer needing the temperature offset by an arbitrary amount. But the oversight was the Family 17h Model 70h ID was never added to the AMD k10temp driver. As a result, temperature monitoring wasn't actually working and took an extra kernel cycle before this trivial addition landed.

  • All about Reactive Foundation,The Linux Foundation's new baby

    The Linux Foundation has announced the launch of the Reactive Foundation, a community of leaders established to accelerate technologies for building the next generation of networked applications. The foundation is made up of Alibaba, Lightbend, Netifi and Pivotal as initial members and includes the successful open source RSocket specification, along with programming language implementations.

    The aim of reactive programming is to build applications that maintain a consistent user experience regardless of traffic on the network, infrastructure performance and different end-user devices (computers, tablets, smartphones). Reactive programming uses a message-driven approach to achieve the resiliency, scalability, and responsiveness that is required for today's networked cloud-native applications, independent of their underlying infrastructure. The Reactive Foundation establishes a formal open governance model and neutral ecosystem for supporting open source reactive programming projects.

The Reactive Foundation establishes a formal open governance model and neutral ecosystem for supporting open source reactive programming projects.
    "From the beginning of our work on RSocket during my time at Netflix, our intent was to have an open system that encouraged broad adoption, which is essential for networking technology. We're thrilled to be hosted at the Linux Foundation with commitment from leaders and disruptors in the industry, and are excited to make progress enabling reactive programming," said Ryland Degnan, Co-Founder, and CTO at Netifi and Foundation community chair.

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.
