Linux Kernel Events

  • Plumbers and CKI hackfest highlights

    Laura Abbott led the distribution kernel microconference. The main goal was to discuss common problems arising from maintaining a non-mainline kernel, whether it comes to keeping in sync with bugfixes, packaging or testing. A lot of the topics circled around leveraging the similar work everyone is doing and figuring out common tooling and some discussions even lead to the distribution testing BoF.

    One of the great ideas mentioned was configuration fragments in the mainline – if you want to enable a feature you have to find out what the specific set of config options to enable is. Having the options condensed based on the features in the mainline kernel itself would make this enabling/disabling simpler and cleaner for everyone (users wanting to compile their own kernels, CIs, distribution maintainers…). The initial action plan is to send various feature fragments to the automated testing mailing list to compare and discuss specifics before pushing them upstream.

    Another action item directly related to the previous one was to update upstream configuration file merging. Each distribution has its own implementation, usually in a form of legacy perl script everyone is afraid to touch but depends on heavily. Using the upstream version (once it provides the functionality distributions need) instead of maintaining scripts on top of kernel would both simplify the work of maintainers and provide an easier way to build their own kernels to users.

    The arguably most important was the testing discussion. Distributions usually carry some patches on top of the mainline or stable releases they follow but these differences are small enough that comparing test results can help with pinpointing bugs in the base. This is however easier said than done as figuring out which tests to run is hard. The suites are not linked from the actual kernel sources, tests may be failing because of kernel or test bugs, you want a stable test release but also tests for new kernel features…

  • Kernel Recipes 2019, part 2

    This conference only has a single track, so I attended almost all the talks. This time I didn't take notes but I've summarised all the talks I attended. This is the second and last part of that; see part 1 if you missed it.

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.
