  • Python uppercase string – Linux Hint

    The upper() function translates all the lowercase characters in a string into uppercase and returns the string. The upper() function is an integral function in Python. In certain cases, the upper() function is very useful. For example, if we are developing a university management system and want to convert the name of all the students into uppercase letters, in this case, we will definitely use the upper() function. This article explains the use of the upper() function with the help of simple examples.

  • Basics of Parsing Command Line Arguments in Python | FOSS Linux

    Command-line applications are one of the oldest and most used types of apps. If you are an experienced Linux user, you may have hardly used GUI tools instead of command-line tools to do the same task. For example, Anaconda, the package manager for python, has command-line tools named conda and GUI tool named anaconda navigator.

  • How To Take A Screenshot Using Python & Selenium? | Codementor

    The goto software framework for any web developer looking for an open-source, free test automation tool is Selenium.

  • How To: Simple HTTP Server with Python

    When building new infrastructure elements and deploying servers, quite often you need to test firewall rules before the rest of application stack is deployed. The basic tool of my choice here is curl which is great to testing TCP connections. But it has an important dependency: you actually need to have something listening on the other end of the connection you’re testing. If there’s no software running and servicing the port you specify, you will receive an error.

    Traditionally there have been small programs or scripts you’d write - first (many years ago now) in C, later in Perl. They would imply that you have to bring your test code or compiled binary to the server you need to test.

    Today I’d like to share a super easy way to start a basic HTTP server with Python - it’s literally just one line that will work in most cases since Python is now ubiqutous enough to be installed by default in most Linux distributions.

  • 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.
