  • Python Queue – Linux Hint

    Python provides many built-in modules, functions, and statements that help the programmers to perform various complicated tasks easily. It also provides many built-in data structures like lists, tuple, and dictionaries, which ensure the efficient creation and management of data in applications. A queue is a data structure that stores and manages the data. It stores the data in a first-in, first-out (FIFO) order. The element that is inserted first will be removed first. We can understand the working of the queue from our daily life example. It‘s like a queue of customers; the customer who comes first is facilitated first.

  • Python Multi-line Comments – Linux Hint

    Every programming language provides a mechanism to add comments to projects. Comments are the simple lines in computer programs that are ignored by the compiler or interpreter. Comments are often written in natural language to increase programmer comprehensibility. Developers use comments to ignore some parts of the code in the debugging or testing phase.

    Writing comments in Python can be very simple, and creating a comment in Python begins with the ‘#’ symbol. This article explains how to create multi-line comments in Python.

  • How to Join Lists in Python – Linux Hint

    Lists are an important data structure in Python, used to store multiple elements in a single container. Python lists can store both similar types and heterogeneous types of elements. In Python, you can join or concatenate two or more lists. Joining a list merges numerous lists into a single list. This article explains the joining or concatenation of Python lists in several ways.

  • Python Zip File – Linux Hint

    Python is a general-purpose programming language. It is widely used in machine learning, deep learning, artificial intelligence, and data sciences projects. Python is loaded with handy built-in modules, functions, and statements. Therefore, it helps the programmers a lot to perform many types of tasks. Performing the file related task in Python is super easy due to the availability of related modules. We can perform any type of file-related tasks, i.e., reading, writing, searching, and deleting a file.

    ZIP is a popular format of files that offers lossless compression. A ZIP file contains one or many compressed files and is a single file. The compression algorithms ensure that we can recreate the actual data from the compressed data without any loss. There are several benefits of using the zip file. By using the zip files, we can put all the related data in one single file with reduced file size. Encryption can also be applied while creating zip files. ZIP files are mostly created and used when we need to transfer data through online sources like social media applications and email. It ensures the fastest delivery of data. Python provides a built-in zipfile module to work on the ZIP files. In this guide, we will learn to perform various zip file-related tasks with examples.

  • Python Global Variables – Linux Hint

    In programming language, variables are used to store information. For example, in developing a student management software system, the name, email, and age of a student will be stored in the respective variables. Like other programming languages, Python has both global and local variables. In Python, global variables are declared outside of the function and can be used everywhere in the program. This article explains global variables in Python in detail with some examples.

    The scope of the global variable is very wide, and it is not limited to any specific function. These variables can be used both inside and outside of the function for storing and retrieving information.

  • Python getattr( ) Function – Linux Hint

    The vast variety of Python built-in modules, functions, and statements helps programmers to perform various tasks. The getattr() function is a Python built-in function that allows programmers to access the attribute value of an object. If the value is not found, then the getattar() function returns the default value. This is the reason why the getattr() function is used mostly to access the attribute values of objects. This article will provide a detailed explanation of the getattr() function with some examples.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
