  • Find the coefficients of the Quadratic Equation of the given two roots with Python

    In this example, you are expected to find the coefficients of the quadratic equation of the given two roots (x1 and x2) with a python function.

    The Quadratic Equation looks like this ax^2 + bx + c = 0. Our mission is to find the coefficients of the equations which is a, b, and c. The return type from the function is a Vector containing coefficients of the equations in the order (a, b, c). Since there are infinitely many solutions to this problem, we fix a = 1.

    Below is the method to find the return Vector.

  • Python 3.9.0b4

    Python 3.9 is still in development. This release, 3.9.0b4, is the fourth of five planned beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release.

  • Python 3.9.0b4 is now ready for testing

    On behalf of the entire Python development community, and the currently serving Python release team in particular, I’m pleased to announce the release of Python 3.9.0b4.

  • 10 most useful Python Dictionary Methods

    Dictionary is used in python to store multiple data with key-value pairs. It works like an associative array of other programming languages. The curly ({}) brackets are used to define a dictionary and the key-value is defined by the colon(Smile. The content of the key and value can be numeric or string. Python has many built-in methods to do different types of tasks on the dictionary data such as add, update, delete, search, count, etc. 10 most useful dictionary methods of python are explained in this article.

  • 10 most useful Python String Methods

    The string data is the characters of an array that contains one or more characters as value for any programming language. All printable characters such as alphabets, numbers, special characters, etc. are commonly used in the string data. ASCII code and Unicode are mainly used for converting any character to a number that the computer can understand. Python uses Unicode characters for string data. We need to perform different types of tasks based on the programming purpose on the string data such as searching the particular character or characters, capitalizing the first character, making all characters uppercase, etc. Python has many built-in string methods to do these types of tasks very easily. The 10 most useful python string methods are explained in this article.

  • 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.
