  • Google's UI Toolkit Flutter 2.2 Claims Cross-Platform Crown

    At the recent Google I/O conference, Google announced version 2.2 of its cross-platform UI toolkit, Flutter. According to a study, it is now the most popular cross-platform option. Google concentrated on fixing issues, optimizing performance, and refining existing features in this release. Microsoft, Samsung, Adobe, Sony, and Ubuntu Linux all increased their Flutter support.
    Google cited SlashData's "Mobile Developer Population Forecast 2021" and said that 45% of developers select Flutter now, with a 47% year-over-year growth. This would make Flutter the most popular cross-platform UI toolkit.
    Google also announced that 200,000 apps in the Play Store are built with Flutter. That is 50,000 more than at the end of 2020 and shows a growth rate of 440% since December 2019. In those same 16 months, though, the number of Google teams building Flutter apps only grew by 50%, from "over 20" to "more than 30". For comparison: In the 27 months from February 2019 to April 2021, Google's Angular applications increased 430% from "600+" to "2600 or 2700", as Google Developer Advocate Emma Twersky explained in this podcast (28:35 min).

  • Python Reduce Function Usage – Linux Hint

    Reduce() seems to be a Python method that performs the folding or compression of the mathematical approach. When you’re about to implement a method over an iterable and limit it to a singular cumulative value, reduce() comes in handy. Python’s reduce() method is famous among functional programmers, although Python has many more to offer. You’ll learn how to use reduce() functions and how to implement them efficiently in this article.

  • Python Sleep Function Usage – Linux Hint

    Python sleep () is used to delay the specific processes by adding a sleep function in the source code. The time provided in seconds allows a delay in the process. In this article, we will perform many examples to enhance your knowledge of the sleep method in Python. We have used the Spyder tool for the execution of code.

  • Python Time Module Examples Usage – Linux Hint

    You may use the Python time package to interact with all time-related methods. The majority of them merely call the same-named platform C library routines. There would be minor changes across platforms. The time package is included in all Python releases.

  • 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.
