  • Zstd Compressed Linux Kernel Images Proposed Once More

    Going back to at least late 2017 have been proposals for Zstd-compressing the Linux kernel images for the Facebook-developed Zstandard compression algorithm. In 2020 perhaps we will finally see the support mainlined.

    The 2017 effort didn't gain traction and in 2018 and 2019 it was re-proposed again for supporting Zstd compression for the kernel image and initramfs.

  • Intel Continues Working On Significant GPU Power Optimization For The Linux Kernel

    A set of kernel patches to Intel's graphics driver helps improve the GPU power consumption to the extent of on Chrome OS seeing about 45 minutes extra battery life and several percent under the likes of Ubuntu Linux.

    [...]

    Navik posted the seventh revision to those patches on Monday for context-aware user-agnostic EU/slice/sub-slice control.On a Geminilake platform running Chrome OS he found the battery life to improve by about 45 minutes with ~14% power benefit when watching YouTube content or engaging in WebGL demos. When gaming with Unity 3D, the performance benefit was still a respectable 6%.

    Or on the likes of Ubuntu, with various graphics tests it was in the 2~5% range, however, he hadn't done any YouTube/video tests on that front. But long story short, these patches at a minimum can improve the Intel Linux laptop battery life by several percent.

  • 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.
