  • Linux Is Fine, Nothing to See Here

    Recently, Linux kernel developers were prompted to revoke licenses to their pieces of code to protest against the new Code of Conduct. Over the last week a whole lot of outlets shed light on this event and mused about the morality and potential ramifications of the whole controversy.

    However, ethical and political aspects aside, there are at least two important things to understand: what are the developers opposing and whether they are really able to revoke the licenses for their code. We will try to figure out both as simply and briefly as possible.

    [...]

    The main question here is whether or not “contributors can, at any time, rescind the license grant regarding their property via written notice to those whom they are rescinding the grant from,” as it is put in the original email, urging kernel developers to protest against the Code of Conduct.

    Let’s start with something simple. General Public License is a framework license created by Free Software Foundation for open source software developers. Whenever someone creates a piece of software, they can add certain lines in the end of the code text saying that it is licensed under the GPL. And so, the GPL will apply to anyone who uses this code. Licensees will also be forced to apply the same licensing rules if distributing the code afterwards.

    Note, that GPL is a license in its essence. Hence, it is a legal construction that allows anyone to use a software developed by someone on a legitimate legal basis. It is also important that GPL license was iterated. In this case all the attention goes to GPL version 2.0 and version 3.0.

    The difference in question between GPL v.2.0 and v.3.0 is the inclusion of the non-rescission clause.

  • Intel Linux Graphics Driver Working Towards 5K+ Display Support With VESA DSC

    While 4K displays are great for now, 5K displays are on the horizon and Intel is hard at work preparing their open-source Linux graphics driver for supporting 5K displays and beyond.

    Critical to supporting next-generation monitors at least with DisplayPort interfaces is being able to accommodate DSC or Display Stream Compression. This display compression spec is said to be good enough for handling up to 8K laptop displays. VESA announced it a few years back while it won't be until Icelake CPUs with Gen 11 graphics before Intel is supporting the tech. Icelake is likely to be out either in late 2019 or early 2020, but the open-source driver crew is already working on the support.

  • Learn More About The Zinc Crypto API, Which Hopes To Get Into Linux 5.0 With WireGuard

    Last week at Kernel Recipes 2018 in Paris, WireGuard lead developer Jason Donenfeld presented on the Zinc crypto API that he has been developing for the Linux kernel to suit his in-kernel secure VPN tunnel needs but also to potentially replace the existing Linux crypto code in the future.

    If you are curious about Linux crypto support, Jason has shared his Kernel Recipes presentation on Zinc and it's embedded below.

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.
