  • Javier Martinez Canillas: Fedora 36: A brave new (DRM/KMS only) world

    The upcoming Fedora release includes a change proposed by Peter Robinson and yours truly, that disables all the Frame Buffer Device (fbdev) drivers in the Linux kernel package.

    This means that starting from Fedora 36, only Direct Rendering Manager (DRM) / Kernel Mode Settings (KMS) drivers will be used. No more legacy stuff.

    Many Linux developers have been arguing for over a decade now that fbdev is deprecated and it has been almost 7 years since the previous fbdev maintainer said that no new fbdev drivers would be added to the kernel. So this feels like a change long overdue.

  • The state of fq_codel and sch_cake worldwide - http://blog.cerowrt.org/

    A while back I’d got a small grant from NLNET (thx NLNET!) for a “CeroWrt II” project, to first review the state of the deployed network-latency-fighting art, while gathering new requirements and blue sky ideas for future edge routers, and also verify correct operation of the algorithms the Bufferbloat Project had been trying to make the defaults for the world’s bottleneck links since 2012.

    I was having trouble sleeping at night knowing that every packet for several billion users was now flowing through fq_codel and cake, while we were pushing to finally get those algorithms on more and more headends and cpe, that are hard to upgrade once deployed.

    Were we still killing network latency by 10-100x? Does our stuff scale? Was it deploying? What new problems had come up? After my encounter with Starlink, last year, I was really worried that we were going backwards.

    Dave Täht has put together a summary of the state of fair queuing and the fight against bufferbloat in general.

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.
