    In this tutorial, we will show you how to install Django on Fedora 35. For those of you who didn’t know, Django is a free and open-source high-level Python Web framework built by experienced developers to encourage rapid development and pragmatic design of web applications for programmers and developers. Its main goal is to ease the creation of complex applications and take care of the internal structure.

    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 Django Python Framework on a Fedora 35.

  • C: getsockname Function Usage

    Socket programming is well-known and common in C programming between developers and users. Within this kind of programming, we tend to connect two endpoints. These endpoints can be two servers, one server, one socket, etc. As the name suggests, the “getsockname” function is utilized to get the name of a socket working in the network. It may or may not be the socket name, but the address of that particular socket would be displayed using this function. Therefore, we have tried a simple method to illustrate the getsockname() function in C within this guide. Let’s take a fresh look at its example while working on the program using Ubuntu 20.04 Linux system.

  • How Do I Use Keyboard Shortcuts in Jupyter?

    Jupyter Notebook is a client-server application in which users can edit and run their notebook documents through a browser. The notebook documents that are created in Jupyter notebook consist of python or programming code and rich text elements such as paragraphs, images, links, and equations. When you work as a programmer, you like to use quick keyboard shortcuts to solve the routine work. These shortcuts help you to complete the programming code easier and quickly.

    In Jupyter notebook, various functions and notebook cell options are available that you can manage efficiently using the keyboard shortcuts. Most of the users do not know how they can find and use these shortcuts in the Jupyter notebook. However, today you will learn about all the keyboard shortcuts used in the Jupyter notebook.

  • How to Enable and Use Autocomplete in Jupyter Notebook

    No matter how good you are at writing computer programs, it is hard to remember all function names, syntax, and function parameters. So, programmers are required to use the auto code completion or IntelliSense menu feature in the Jupyter notebook. Usually, programmers and developers are familiar with different auto-completion tools.

    The code autocomplete feature by default included in most of the source code editors through which you can view IntelliSense menu or code suggestions inside the drop-down in a program file. The code autocomplete functionality saves you time for writing complex programs, receives fewer bugs, and you can quickly include methods, attributes, and classes in your code using drop-down suggestions.

  • 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.
