nginx-admins-handbook is a practical, in-depth guide for configuring, securing, and operating NGINX across real-world deployments. It distills years of research, notes, and field experience into a single handbook that complements the official docs with concrete rules, explanations, and curated external references. The handbook spans fundamentals and advanced topics alike, from HTTP and SSL/TLS basics to reverse proxy patterns, performance tuning, debugging workflows, and hardening strategies. A centerpiece is its prioritized checklist of 79 rules, grouped by criticality, helping readers focus on what most impacts security, reliability, and speed. Instead of copy-paste snippets in isolation, it emphasizes understanding trade-offs, avoiding common pitfalls, and balancing security with usability. Designed for system administrators and web application engineers, it aims to be a living companion that encourages experimentation, measurement, and continuous improvement of NGINX configurations

The eng-practices project by Google is a public repository that documents the company’s established engineering best practices, accumulated through years of large-scale software development across diverse teams and languages. Its purpose is to share Google’s collective experience in areas such as code review, collaboration, and quality assurance with the broader software engineering community. The repository provides practical guidelines designed to help developers and reviewers produce cleaner, more maintainable, and higher-quality code. It includes Google’s comprehensive Code Review Guidelines, split into two major sections: The Code Reviewer’s Guide and The Change Author’s Guide, which detail the expectations and processes for both reviewers and authors. Additionally, it explains key terminology and practices commonly used within Google to make the documentation accessible to external audiences.

Natural Docs is an open-source documentation generator for multiple programming languages. You document your code in a natural syntax that reads like plain English. Natural Docs then scans your code and builds high-quality HTML documentation from it. SourceForge houses the source code and issue database for the old Perl version of Natural Docs, version 1.52. It is still available but no longer being updated. Please see NaturalDocs.org for the 2.x source code and issue database. However, you can still download the both the old and the new 2.x releases of Natural Docs here.

Official Support and Documentation for SourceForge.net, provided by the SourceForge.net Service Operations Group (SOG).

og-aws (The Open Guide to Amazon Web Services) is a community-maintained reference that consolidates tips, best practices, and practical knowledge for effectively using AWS. Unlike official AWS documentation, which provides only formal product details, this guide integrates real-world experiences, advice, and caveats gathered from engineers who work with AWS daily. It covers core services such as EC2, S3, IAM, load balancers, and EBS, while also providing insights into optional and advanced services. The guide is designed to be concise, practical, and continuously updated, making it a valuable resource for both beginners and experienced cloud practitioners. It addresses topics like cost management, lock-in risks, service selection, and alternatives, helping users make informed architectural decisions. As a collaborative effort, og-aws grows and evolves with community contributions, ensuring its content remains relevant in the fast-changing cloud ecosystem.

Badges is a utility / site that generates small status badge images for open-source projects (for example, build status, coverage, downloads, version). It allows projects to easily embed dynamic badges in their README or documentation that reflect project metadata or external service metrics. The badges system supports different styles, icons, and dynamic links, making them visually consistent and informative. It abstracts the generation of badge SVGs so the end user doesn’t need to manually create or update image files. The project also supports caching, HTTP APIs, and format options (e.g. to serve badges dynamically or with query parameters). It is used by many open source repos to display real-time project metrics in documentation pages.

This repository contains the source for the Express web site and documentation, the canonical reference for developers using the Express framework. It organizes material into API reference, getting-started guides, best practices, and topic-focused explanations such as routing, middleware, error handling, templating, and performance. Versioned docs help readers match API behavior to the framework version they’re running, reducing confusion during upgrades. The site showcases common patterns through concise examples, making it easy to translate concepts into working code. In addition to core Express usage, the documentation surfaces ecosystem guidance on things like security headers, structured logging, and integration with view engines or ORMs. Because it is open to community contributions, the documentation evolves alongside Express itself, reflecting real-world questions and solutions.
