  • A journey comes to an end

       As this year's Google Summer of Code comes to a close, so does this series of blogposts. Since this is my last post related to GSoC I have decided to summarize my contributions to Xfce and give you a glimpse of what I'll be working on in the foreseeable future. If you have read my previous posts, you can skip right to the end since you have already read most of the stuff that I'm going to write.

    [...]

    Google Summer of Code might be ending, but my job isn't done. I will continue working on adding a decent recursive-search. A lot of progress has been made on that front, but the performance isn't quite there yet. Besides that, I want to give Thunar users an option to easily create Shared Thumbnail Repositories which is something that I will probably do through a new plugin.

  • Arduino partners with Altium and the IPC Education Foundation to launch #PCBeTheChange competition | Arduino Blog

    We’re excited to announce that Arduino has partnered with Altium and the IPC Education Foundation (IPCEF) to launch a student electronics design challenge to engage, educate, and enhance PCB design capabilities while developing STEM solutions to environmental challenges.

    The Innovation for Environmental Change 2021 International Student Design Competition (#PCBeTheChange) encourages student teams to help address common environmental concerns using Altium’s educational tools with Arduino hardware. Teams from high schools and colleges will be using Altium’s Upverter Modular PCB design software and the Portenta H7 to create a prototype design that will improve the environment in each team’s respective local area. The students will be challenged to tackle one or more environmental concerns, such as air pollution, water quality and solar energy capture.

  • ATOI Function in C

    The C programming language contains a collection of useful functions that we can use to perform actions in our program. One such function is the atoi function.
    The atoi function is part of the C standard library. Its primary use is to parse a string and convert its contents to the corresponding numerical value of int type.

    This tutorial will discuss how to use the atoi function to convert strings to integer values in C.

  • LLVM Clang 14 Begins Landing Intel AVX-512 FP16 Support - Phoronix

    Last month Intel began posting the developer documentation around AVX-512 FP16 support coming with Sapphire Rapids and initially accompanied by GCC compiler patches along with LLVM/Clang. While that GNU Compiler Collection support around AVX-512 FP16 has yet to be merged, the LLVM Clang support for this next iteration of AVX-512 has begun landing.

    Next-generation Intel Xeon Scalable "Sapphire Rapids" will support AVX-512 FP16 with full-speed handling of denormal FP16 values - not to be confused with AVX-512 BF16 (BFloat16) found on Cooper Lake. AVX-512 FP16 should help with deep learning models and other cases where FP32 isn't necessary.

  • 9 digital transformation truths that the pandemic rewrote | The Enterprisers Project

    In the seeming blink of an eye, the pandemic changed everything: how we worked, shopped, went to school, entertained ourselves, got medical or mental health care, engaged with government agencies, and connected with friends and family. “The world shut down and everything was forced to adapt,” says MJ Johnson, managing director in the product and experience lab at business and technology consultancy West Monroe. “Every part of society was affected.”

    The pandemic has also rocked many of the core tenets of digital transformation. “With a forced change of this magnitude, we witnessed the impossible become possible,” Johnson says. “Projects that would have taken years took just weeks, business models that were dependent on being ‘in-person’ successfully pivoted to being delivered digitally, and customers ultimately adapted and found businesses that pivoted gracefully throughout the pandemic. Our assumptions and beliefs have completely changed.”

    "The result was accelerated, barrier-breaking service delivery."

  • Building an adaptable 5G Core on an open source container platform

    5G aims to enable the delivery of highly immersive experiences for people and ultra reliable, low latency communication between devices. At the heart of each 5G network lies the 5G Core (5GC), with service providers needing to make several key decisions when building the 5G Core.

    Their platform should be able to support a wide range of use cases without adding operational complexities and cost. The proposed architecture conceives 5G Core as a set of disaggregated, cloud native applications that communicate internally and externally over well defined standard interfaces.

    Each 5GC component is implemented as a container-based application and is referred to as cloud-native network function (CNF). This requires the container platform to support functionalities and operational features like automated deployment, intelligent workload placement, dynamic scaling, hitless upgrades, and self healing.

    This post covers how to architect an open 5G Core solution with cloud-native technologies, focusing on an on-premise, stand-alone deployment approach.

  • 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.
