Nmap

Nmap (Network Mapper) is a free and open-source network discovery and security auditing tool used to scan networks for hosts, services, and vulnerabilities. It helps identify devices on a network, detect open ports, determine service versions, and assess security risks. Widely used by network administrators, security professionals, and ethical hackers, it supports various scanning techniques and scripting for advanced tasks.

Also known as: Network Mapper, Nmap Scanner, Zenmap, Nmap Scripting Engine, NSE

🧊Why learn Nmap?

Developers should learn Nmap for network troubleshooting, security testing, and penetration testing in DevOps or cybersecurity roles. It's essential for identifying open ports in applications, verifying firewall configurations, and conducting vulnerability assessments during development or deployment phases. Use cases include pre-deployment security checks, monitoring network infrastructure, and automating network inventory tasks.

Other Testing and Inspection

.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 enabling HTTPS, blocking IP addresses, or setting custom error pages.

2D Drafting is the process of creating technical drawings and schematics in two dimensions using specialized software, primarily for engineering, architecture, and manufacturing design. It involves producing precise, scaled representations of objects, components, or structures with detailed annotations, dimensions, and symbols to communicate design intent and specifications. This skill is foundational for translating conceptual ideas into actionable plans for construction, fabrication, or analysis.

2D Drafting Tools

2D drafting tools are software applications used to create precise technical drawings, schematics, and blueprints in two dimensions. They enable engineers, architects, and designers to produce detailed plans with accurate measurements, annotations, and geometric shapes. These tools are essential for documenting designs before moving to 3D modeling or physical construction.

2D Drawing Review

2D Drawing Review refers to the process and software tools used to examine, annotate, and collaborate on two-dimensional technical drawings, such as blueprints, schematics, or CAD designs. It involves checking for accuracy, compliance with standards, and identifying errors or improvements in engineering, architecture, or manufacturing contexts. Tools for this purpose often include features like markup, version control, and real-time collaboration to streamline review cycles.

2D Graphics Software

2D graphics software refers to computer programs used to create, edit, and manipulate two-dimensional digital images, illustrations, and designs. These tools provide features like drawing, painting, vector graphics, image editing, and layout design for applications such as digital art, UI/UX design, game sprites, and print media. They range from professional suites like Adobe Photoshop to free alternatives like GIMP and Inkscape.
