GitHub Actions

GitHub Actions is a CI/CD platform created and maintained by GitHub (Microsoft). Unlike standalone CI tools like Jenkins or CircleCI, it integrates directly into GitHub repositories, enabling automated workflows triggered by repository events like pushes or pull requests. Companies like Shopify use it for continuous deployment of their e-commerce platform, while Netflix employs it for testing microservices. A key technical detail is its YAML-based workflow syntax where jobs run in parallel by default unless explicitly chained with 'needs' dependencies.

Also known as: gha, gh-actions

🧊Why learn GitHub Actions?

Use GitHub Actions when your project is hosted on GitHub and you need seamless integration with repository events, such as automating tests on every pull request. It is not the right pick for complex multi-cloud deployments requiring deep vendor-specific integrations, where tools like GitLab CI/CD might be better. The community acknowledges a weakness in limited customization of runner environments compared to self-hosted solutions like Jenkins.

Other CI/CD Tools

.env is a file format and tool used to store environment variables, which are key-value pairs that configure application settings like API keys, database URLs, and other sensitive or environment-specific data. It allows developers to separate configuration from code, making applications more secure and portable across different environments (e.g., development, testing, production). Tools like dotenv in Node.js or python-dotenv in Python parse .env files to load these variables into the application's environment at runtime.

.htaccess (Hypertext Access) is a configuration file used on Apache web servers to control directory-level settings, such as URL redirection, access control, and performance optimizations. It allows developers to override global server configurations for specific directories without modifying the main server configuration files. This file is commonly used for tasks like password protection, custom error pages, and enabling features like mod_rewrite for URL manipulation.

.htaccess (Hypertext Access) is a configuration file used on Apache web servers to control directory-level settings, such as URL redirection, access control, and performance optimizations. It allows developers to override global server configurations for specific directories without modifying the main server configuration files. This file is commonly used for tasks like enabling HTTPS, blocking IP addresses, or setting custom error pages.

.htaccess Redirect

.htaccess redirect is a server-side configuration technique using the .htaccess file on Apache web servers to manage URL redirections, such as redirecting old URLs to new ones, enforcing HTTPS, or handling errors like 404 pages. It operates through directives like Redirect, RedirectMatch, and RewriteRule, allowing developers to control traffic flow without modifying server-wide settings. This method is essential for SEO, user experience, and maintaining link integrity during website migrations or updates.

.NET Interactive

.NET Interactive is an open-source tool that enables interactive programming experiences across multiple languages (C#, F#, PowerShell, SQL, HTML, JavaScript) within notebooks like Jupyter, Visual Studio Code, and Azure Data Studio. It allows developers to create and share executable documents that combine code, visualizations, and narrative text, facilitating data exploration, documentation, and teaching. The tool integrates with the .NET ecosystem, providing rich output capabilities and extensions for data science and machine learning workflows.

.NET Profiling Tools

.NET profiling tools are software utilities used to analyze the performance, memory usage, and behavior of .NET applications during execution. They help developers identify bottlenecks, memory leaks, and inefficiencies by collecting data on CPU usage, garbage collection, thread activity, and method execution times. These tools are essential for optimizing .NET applications to ensure they run efficiently and reliably in production environments.
