Writing Custom Ansible Modules in Python: Introduction Ansible is an open-source automation tool that helps you automate configuration management, application deployment, and task automation. It is agentless, which means it doesn’t require any software to be installed on remote systems. Ansible modules are the building blocks of any Ansible playbook, and they are responsible for executing specific tasks on managed hosts. While Ansible comes with a large number of built-in modules, you may encounter situations where you need to write your own custom module to perform a specific task that isn’t covered by the existing modules.…

Introduction to 3D modeling and its applications Three-dimensional (3D) modeling is the process of creating a digital representation of a physical object or scene. It has numerous applications in various fields such as video games, films, architecture, engineering, and medicine. Python is a popular programming language that can be used for 3D modeling due to its ease of use, readability, and large number of libraries and packages. Python’s packages like NumPy, Matplotlib, and VPython provide functionality for working with 3D objects and visualization.…

Introduction to Ansible and Python libraries Ansible is an open-source automation tool that allows you to manage and automate the configuration of multiple systems at the same time. It is known for its simplicity, ease of use, and powerful features. Ansible provides a wide range of modules and plugins that allow you to automate various tasks such as installing packages, configuring services, and managing files. Python, on the other hand, is a widely-used high-level programming language that is known for its readability, ease of use, and versatility.…

Introduction to Ansible Inventories and Python Ansible is an open-source IT automation tool that allows you to automate tasks across multiple servers. It accomplishes this by using inventories, which are lists of hosts and groups of hosts that Ansible can manage. An inventory file typically contains information about the hosts, such as their IP addresses or domain names, as well as information about the groups to which each host belongs.…

Introduction to Image Enhancement Techniques Images captured through various mediums such as cameras, scanners, etc. often contain unwanted noise and imperfections. Image enhancement techniques are used to improve the visual quality of these images by removing or reducing such imperfections. The image enhancement process can be divided into two categories: point processing and neighborhood processing. Point processing techniques modify each pixel of the image independently, whereas neighborhood processing techniques use the neighboring pixels to modify each pixel in the image.…
