How to Learn API Development?
Learning how to develop APIs is an important skill for modern-day developers. Here’s a mind map of what all you need to learn about API development:
API Fundamentals
What is an API, types of API (REST, SOAP, GraphQL, gRPC, etc.), and API vs SDK.API Request/Response
HTTP Methods, Response Codes, and Headers.Authentication and Security
Authentication mechanisms (JWT, OAuth 2, API Keys, Basic Auth) and security strategies.API Design and Development
RESTful API principles include stateless, resource-based URL, versioning, and pagination. Also, API documentation tools like OpenAPI, Postman, Swagger.API Testing
Tools for testing APIs such as Postman, cURL, SoapUI, and so on.API Deployment and Integration
Consuming APIs in different languages like JS, Python, and Java. Also, working with 3rd party APIs like the Google Maps API and the Stripe API. Learn about API Gateways like AWS, Kong, Apigee.
Over to you: What else will you add to the list for learning API development?
Must-Know Network Protocol Dependencies
Understanding network protocol dependencies is essential for cybersecurity and networking. Here’s a quick understanding of the same:
IPv4 and IPv6 are the foundation of all networking. ICMP and ICMPv6 handle diagnostics, while IPsec ensures secure communication.
TCP and UDP support various protocols. SCTP and DCCP serve specific cases.
Some TCP-based protocols are HTTP, SSH, BGP, RDP, IMAP, SMTP, POP, etc.
UDP-based protocols are DNS, DHCP, SIP, RTP, NTP, etc.
SSL/TLS encrypts HTTPS, IMAPS, and SMTPS.
LDAP and LDAPs are used for directory services over TCP and secured with SSL/TLS.
QUIC is a UDP-based replacement for TCP+TLS for faster, encrypted connections.
MCP or Model Context Protocol is an emerging standard for communicating with LLMs.
Over to you: Which other network protocol will you add to the list?

18 Key Design Patterns Every Developer Should Know
Patterns are reusable solutions to common design problems, resulting in a smoother, more efficient development process. They serve as blueprints for building better software structures. These are some of the most popular patterns:
Abstract Factory: Family Creator - Makes groups of related items.
Builder: Lego Master - Builds objects step by step, keeping creation and appearance
Prototype: Clone Maker - Creates copies of fully prepared examples.
Singleton: One and Only - A special class with just one instance.
Adapter: Universal Plug - Connects things with different interfaces.
Bridge: Function Connector - Links how an object works to what it does.
Composite: Tree Builder - Forms tree-like structures of simple and complex parts.
Decorator: Customizer - Adds features to objects without changing their core.
Facade: One-Stop-Shop - Represents a whole system with a single, simplified interface.
Flyweight: Space Saver - Shares small, reusable items efficiently.
Proxy: Stand-In Actor - Represents another object, controlling access or actions.
Chain of Responsibility: Request Relay - Passes a request through a chain of objects until handled.
Command: Task Wrapper - Turns a request into an object, ready for action.
Iterator: Collection Explorer - Accesses elements in a collection one by one.
Mediator: Communication Hub - Simplifies interactions between different classes.
Memento: Time Capsule - Captures and restores an object's state.
Observer: News Broadcaster - Notifies classes about changes in other objects.
Visitor: Skillful Guest - Adds new operations to a class without altering it.
