The free and widely-used editor for Windows supports not only basic search and replace functions but also regular expressions. A helpful plugin assists in formulating regex, providing real-time expression validation. However, for many tasks you don't need regex; built-in functions and plugins often offer simpler solutions.

Most of the time, merging branches in Git is an automatic process of integrating the changes on one branch into another. Sometimes, a conflict prevents Git from completing the process without human intervention. This article briefly examines content (line) merge conflicts and how to resolve them. If you are new to Git, please read the previous guides in this Git beginner series.

Ansible's service module is used to manage services on remote systems. The service module is handy for tasks related to starting, stopping, restarting, and checking the status of services. It provides a consistent and declarative way to manage services across different operating systems. In this tutorial, we will explore how to use the Ansible service module with detailed examples to showcase its capabilities.

The provided Bash and PowerShell script helps automate the creation of Amazon Machine Images (AMIs) from existing AWS Elastic Compute Cloud (EC2) instances. This is particularly useful for creating point-in-time backups or disaster recovery. I mostly use the script to quickly clone an EC2 instance for testing or troubleshooting.

In my previous article, I discussed merge conflicts, specifically line merge conflicts, and how to resolve them on GitHub. In this article, I will focus on another type of merge conflict, the modify/delete conflict, and how to resolve it using Git.

Ansible variables store and manipulate data that can be accessed and utilized across playbooks, roles, and tasks. They allow for dynamic configurations and flexible automation by enabling the abstraction of values that may change based on different environments or use cases.

GUI solutions for Ansible, such as Red Hat’s Ansible Tower and PagerDuty’s RunDeck, come with a significant license cost, whereas the free versions are limited in features and complicated to install. Developed with ease of use in mind, Semaphore provides a GUI for Ansible with a set of powerful features.

Sometimes, the remote extensions that are installed by Microsoft Visual Code (VS Code) on remote systems can consume high amounts of CPU usage, making it difficult to use the server efficiently. However, my script can help limit the CPU usage of VS Code on a remote server.

Pulumi is an infrastructure-as-code (IaC) solution similar to Terraform. One advantage of Pulumi is that it allows DevOps engineers to use familiar programming languages to define, deploy, and manage cloud infrastructure. This post demonstrates how to deploy an EC2 instance with Pulumi.

This post will guide you in debugging containerized apps running in Docker using Visual Studio (VS) Code.

You can manage Docker images and containers directly within Visual Studio Code (VS Code) with Microsoft's Docker extension. This article walks you through adding Docker files to a Workspace, creating a containerized application environment, and explains how to build and run Docker containers directly from the VS Code interface.

JSON (JavaScript Object Notation) is gaining popularity as a format for configuration files. Unlike XML or the still-used INI format, editing JSON in a text editor can be tedious and error-prone. However, there are free JSON editors and plugins for Notepad++ that simplify this task.

This article will explain the four ways to upgrade to a new version of Python on a Windows system: installer, Microsoft Store, Winget, and Chocolatey. You will also learn how to use different versions of Python on your system and how to uninstall an old version.

Dev Drive is a new feature in Windows 11 23H2, also included in the preview of Windows Server 2025. It is a drive based on ReFS, specifically designed for the requirements of developers and IT professionals. It offers enhanced control over volume settings and file system filters.

If you want to deploy a web server like Apache or Nginx with Ansible, you can create a playbook outlining the installation and configuration steps. This approach works well for a single web server but can become repetitive and time-consuming if you need to deploy many servers. To streamline the process, you can use Ansible roles to avoid duplicating tasks and make deployment more efficient. To introduce the concept, this post provides a simple example of using Ansible roles.

Docker Desktop is designed for developers working on macOS and Windows. It offers a user-friendly interface for running Docker containers. It uses a lightweight virtual machine (VM) with a Linux kernel in the background so that you can run Linux containers on non-Linux systems. Docker Desktop does a great job hiding all the aspects of the VM under the hood so that Docker containers appear to be running natively on your host computer. Docker Desktop received an update a few days ago, and in this post, we will discuss what's new in Docker Desktop 4.28.

ShellGPT is an AI tool for Windows, macOS, and Linux that integrates OpenAI's GPT with standard command-line interfaces such as PowerShell, CMD, Bash, and Zsh. The AI integrated into your shell can generate shell commands and code snippets directly from the command line. In this guide, I'll walk you through installing ShellGPT, explain how you can use the tool with a local installation of LM Studio, and give examples of how to use ShellGPT.
