  • How to Resize Images Using Python

    Python has become the go-to choice for a programming language; not only for general object-oriented programming but for various scientific, mathematical, statistical, etc. applications.

    All this has been possible due to a strong developer community that has developed libraries and APIs for every purpose, in Python. From machine learning to medicine, it has libraries for all sectors.

    SPVM is a module that can convert Perl-like source code into C language and execute it.

    I have succeeded in generating an executable in a very stable way.

  • Rakudo Weekly News: 2021.06 Collect, Conserve, Remaster

    Elizabeth Mattijsen has started the Raku Collect, Conserve, Remaster Project to collect old blog posts from the 20+ year history of Raku, into a repository with the goal of preserving all of the information in these blog posts (many of which have already disappeared from the directly accessible internet). If you know of old blog posts (possibly your own), please create a PR to have them added to the Collect phase of the CCR project. The preliminary results are Remastered blog posts in markdown format, that can be rendered at a later stage to provide more up-to-date Raku content on the Internet (/r/rakulang comments).

  • How to overcome today’s development challenges for mobile and smart devices with Qt and Felgo

    Qt makes it easy to develop applications for Desktop, Mobile and Embedded platforms, all from a single code base. No other solution offers to build native cross-platform apps for all these platforms at once. But since the rise of mobile and smart devices in all kinds of shapes and sizes, bridging the gap between platforms has become even harder. By solving a lot of common problems in many real-life projects, Felgo built a variety of higher-level APIs and development tools on top of Qt that help you save time and worries. Read on to learn how to overcome these challenges from the development to the release.

  • Mozilla Welcomes the Rust Foundation

    Today Mozilla is thrilled to join the Rust community in announcing the formation of the Rust Foundation. The Rust Foundation will be the home of the popular Rust programming language that began within Mozilla. Rust has long been bigger than just a Mozilla project and today’s announcement is the culmination of many years of community building and collaboration. Mozilla is pleased to be a founding Platinum Sponsor of the Rust Foundation and looks forward to working with it to help Rust continue to grow and prosper.

    Rust is an open-source programming language focused on safety, speed and concurrency. It started life as a side project in Mozilla Research. Back in 2010, Graydon Hoare presented work on something he hoped would become a “slightly less annoying” programming language that could deliver better memory safety and more concurrency. Within a few years, Rust had grown into a project with an independent governance structure and contributions from inside and outside Mozilla. In 2015, the Rust project announced the first stable release, Rust 1.0.

  • Rust Foundation Established To Steward The Rust Programming Language

    Mozilla has been sponsoring the Rust programming language for more than a decade while in 2020 as part of Mozilla's big round of layoffs most of the Rust team was let go along with dropping the Servo web engine team. Following that plans were drafted to create the Rust Foundation as an independent entity.

  • Hello World! [Ed: Microsoft is in the Board of the Rust Foundation]

    Today, on behalf of the Rust Core team, I’m excited to announce the Rust Foundation, a new independent non-profit organization to steward the Rust programming language and ecosystem, with a unique focus on supporting the set of maintainers that govern and develop the project. The Rust Foundation will hold its first board meeting tomorrow, February 9th, at 4pm CT. The board of directors is composed of 5 directors from our Founding member companies, AWS, Huawei, Google, Microsoft, and Mozilla, as well as 5 directors from project leadership, 2 representing the Core Team, as well as 3 project areas: Reliability, Quality, and Collaboration.

  • 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.
