  • How I teach Python on the Raspberry Pi 400 at the public library |

    After a long and tough year, I've been looking forward to once again sharing my love of Python and open source software with other people, especially middle and high school students. Before the pandemic, I co-wrote a grant to teach Python programming to middle school students using Raspberry Pi computers. Like many other plans, COVID-19 put mine on hold for over a year. Fortunately, vaccines and the improved health in my state, New York, have changed the dynamic.

    A couple of months ago, once I became fully vaccinated, I offered to self-fund a Raspberry Pi and Python programming course in our local public library system. The Chautauqua-Cattaraugus Library system accepted my proposal, and the co-central library in Olean, N.Y., offered to fund my program. The library purchased five Raspberry Pi 400 units, Micro-HDMI-to-VGA adapters, and inline power adapters, and the library system's IT department loaned us five VGA monitors.

  • Speech to Text – Linux Hint

    Speech recognition is a technique that converts the human voice to text. This is a very important concept in the Artificial Intelligence world where we have to give commands to a machine like a driverless car, etc.

  • Iterate Through Dictionary Python – Linux Hint

    Just like a regular manual dictionary, a Python dictionary also works in the same way. The dictionary helps the user in storing and manipulating data in different data structures. Items of the dictionary are changeable, ordered, and concurrent. In this article, we will elaborate on the working of Python dictionaries.

  • Python Zip Function Examples – Linux Hint

    The zip() method in Python builds an iterator that combines items from several iterables. The iterator that results may be used to handle basic programming challenges such as constructing dictionaries. The zip() method accepts a list of iterables, which might be zero or maybe more, and returns a tuple. But when you give it a tuple, you must convert the resultant list into a tuple first. You will learn how to utilize the Python zip() method to tackle real-world situations in this article using Ubuntu 20.04 Linux System. First of all, we need to log in from the Ubuntu Login panel after starting it.

    After the login, you have to make sure that your system and its apt package are updated to the current date to work efficiently on Python. Then, launch the Ubuntu 20.04 command-line terminal to work on the console. You can open it from the shortcut key “Ctrl+Alt+T” or otherwise open it from the activity search bar from the applications provided in the corner. After opening the terminal, we need to update the apt package from the mentioned below query.

  • Using Namedtuple in Python – Linux Hint

    Python comes with an inbuilt module called collections, which provides various classes and functions as an alternative to Python inbuilt data structures such as dict, list, set, and tuple.

    This Python tutorial will discuss namedtuple, one of the factory functions of the collections’ module. We will go through all the important concepts of Python namedtuple with examples and syntax.

  • How to Use the Counter Module in Python – Linux Hint

    This article will explain how to use the “Counter” module that comes by default with the Python programming language. All code samples in this article are tested with Python version 3.9.5 on Ubuntu 21.04.

  • 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.
