  • QEMU 6.2 Emulator Released - itsfoss.net

    The presented release of the project is QEMU 6.2 . As an emulator, QEMU allows you to run a program compiled for one hardware platform on a system with a completely different architecture, for example, to run an application for ARM on an x86-compatible PC. In virtualization mode in QEMU, the performance of code execution in an isolated environment is close to the hardware system due to the direct execution of instructions on the CPU and the use of the Xen hypervisor or the KVM module.

    The project was originally created by Fabrice Bellard to enable x86-built Linux binaries to run on non-x86 architectures. Over the years, support for full emulation has been added for 14 hardware architectures, the number of emulated hardware devices has exceeded 400. In the preparation of version 6.2, more than 2300 changes were made from 189 developers.

  • PAPPL 1.1 Open-Source Printer Framework Adds WiFi Configuration, IPP-USB

    While CUPS 2.4 was recently released as the first big update in years and since OpenPrinting took over upstream development, CUPS founder Michael Sweet continues concurrently developing PAPPL as a modern, open-source printer appication framework. Wednesday marked the release of PAPPL 1.1.

  • New user guide for Base

    Another user guide was published by the LibreOffice documentation team on December 8: the LibreOffice 7.2 Base Guide, for the database component. It is available in free PDF or ODT from the LibreOffice website, or in a low-cost printed copy from Lulu.com.

    Given the very few changes in Base since LibreOffice 6.4, the team decided to just rebrand the previous book, as part of an effort to produce a complete set of books for v7.2. If you want printed copies and already have the Base 6.4 book, you could choose to save some money by not buying this one.

  • Sublime ❤︎ Clojure

    REPL is Clojure’s superpower. For a long time, I’ve been enjoying Sublime Text but was unable to match it with Clojure. This ends today: I’m happy to present my new Sublime Text plugin, Sublime Clojure.

  • Python discusses deprecations [LWN.net]

    Feature deprecations are often controversial, but many projects find it necessary, or desirable, to lose some of the baggage that has accreted over time. A mid-November request to get rid of three Python standard library modules provides a case in point. It was initially greeted as a good idea since the modules had been officially deprecated starting with Python 3.6; there are better ways to accomplish their tasks now. But, of course, removing a module breaks any project that uses it, at least without the project making some, perhaps even trivial, changes. The cost of that is not insignificant, and the value in doing so is not always clear, which led to higher-level conversation about deprecations.

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.
