There is some interesing news regarding Docker and its future. Then we’ll check out some Linux Gaming news with some really exciting news from Valve! 

  • PostgreSQL 12 boosts open source database performance

    Performance gains are among the key highlights of the latest update of the open source PostgreSQL 12 database.

    PostgreSQL 12 became generally available Oct. 3, providing users of the widely deployed database with multiple enhanced capabilities including SQL JSON query support and improved authentication and administration options. The PostgreSQL 12 update will potentially affect a wide range of use cases in which the database is deployed, according to Noel Yuhanna, an analyst at Forrester Research.

    "Organizations are using PostgreSQL to support all kinds of workloads and use cases, which is pushing the needs for better performance, improved security, easier access to unstructured data and simplified deployments," Yuhanna said. "To address this, PostreSQL12 improves performance by improving its indexing that requires less space and has better optimization to deliver faster access."

  • Heading levels

    the headings would be “Apples” (level 1), “Taste” (level 2), “Sweet” (level 3), “Color” (level 2). Determining the level of any given heading requires traversing through its previous siblings and their descendants, its parent and the previous siblings and descendants of that, et cetera. That is too much complexity and optimizing it with caches is evidently not deemed worth it for such a simple feature.

    However, throwing out the entire feature and requiring everyone to use h1 through h6 forever, adjusting them accordingly based on the document they end up in, is not very appealing to me. So I’ve been trying to come up with an alternative algorithm that would allow folks to use h1 with sectioning elements exclusively while giving assistive technology the right information (default styling of h1 is already adjusted based on nesting depth).

    The simpler algorithm only looks at ancestors for a given heading and effectively only does so for h1 (unless you use hgroup). This leaves the above example in the weird state it is in in today’s browsers, except that the h1 (“Color”) would become level 2. It does so to minimally impact existing documents which would usually use h1 only as a top-level element or per the somewhat-erroneous recommendation of the HTML Standard use it everywhere, but in that case it would dramatically improve the outcome.

  • openSUSE OBS Can Now Build Windows WSL Images

    As Windows Subsystem for Linux (WSL) is becoming a critical piece of Microsoft’s cloud and data-center audience, openSUSE is working on technologies that help developers use distributions of their choice for WSL. Users can run the same WSL distribution that they run in the cloud or on their servers.

    The core piece of openSUSE’s WSL offering is the WSL appx files, which are basically zip files that contain a tarball of a Linux system (like a container) and a Windows exe file, the so called launcher.

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.
