  • Marcus Lundblad: Christmas Maps

    So it's that time of the year again and about time for an end-of-year post.
    Some news in Maps for the upcoming GNOME 42.

    Finally, we have added support for running development versions of Maps (such as from the Nightly Flatpak repo) in parallel with the stable ones

    The develop one is distinguished by the “cogwheel” background in the headerbar, and also by it's ”bio-hazard” strip icon as seen above.

  • AMD AOCC 3.2 Helps Squeeze A Bit More Out Of Zen 3 - Phoronix

    Released earlier this month was AMD's AOCC 3.2 compiler based on LLVM/Clang/Flang that provides optimized support for AMD Zen processors.

  • Intel oneAPI Toolkits 2022 Released - Phoronix

    Intel has now made their oneAPI Toolkits 2022 release publicly available after announcing it earlier this quarter.

    Intel's oneAPI Toolkits offers a wide assortment of open-source software components for maximizing the potential out of Intel hardware from CPUs to GPUs/XPUs. This includes packages from their oneDNN deep learning library to their Data Parallel C++ compiler, optimized Python packages like for TensorFlow and PyTorch, OpenVINO, and a lot more. It's quite an incredible assortment of packages at this point and quite useful to developers.

  • QML Component Design - KDAB

    In a well-designed QML application, the UI is built using re-usable components, while the data and logic live in C++ based components we call controllers here. The QML part of the application uses these components (that themselves may be written in QML or C++) to build up the user interface and connect these components with the controllers. In this setup, the controllers provide the data as well as receive input from the UI. How hard can it be?

  • Registry of pickles for GNU poke

    GNU poke allows the users to write their own descriptions of the data they want to edit or operate with. These descriptions are written in the Poke programming language, and consist on type definitions, variables, functions, pretty-printers and so on.
    We call 'pickles' to Poke source files containing definitions of types, variables, functions, etc, that conceptually apply to some definite domain. For example, is a pickle that provides facilities to poke ELF object files. Pickles are not necessarily related to file formats: a set of functions to work with bit patterns, for example, could be implemented in a pickle

  • 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.
