C++ Smart Pointers

Automatic memory management in C++ using smart pointers like unique_ptr, shared_ptr, and weak_ptr to prevent memory leaks and simplify resource handling.

C++

RAII Principle

Resource Acquisition Is Initialization (RAII) ensures automatic resource management by tying resource lifecycle to object lifetime, preventing resource leaks.

Pointer Arithmetic

Explore how pointers can be incremented and decremented to navigate through memory, enabling efficient array traversal and manipulation in C.

C++

Move Semantics

Efficiently transfer resources between objects by moving instead of copying, reducing unnecessary memory allocations and improving performance.

malloc Memory Allocation

Dynamic memory allocation in C using malloc() to create memory space at runtime, which must be manually freed to prevent memory leaks.

Dynamic Memory Malloc

Dynamically allocate memory at runtime using malloc() to create flexible memory management in C programs

Bitwise XOR Swap

Learn how to swap two variables without using a temporary variable by leveraging the XOR bitwise operation in C

Bitwise Operators

Explore bitwise operators in C for low-level bit manipulation, useful in embedded systems, optimization, and binary logic operations.

Bitwise Operations

Explore bitwise operators in C for efficient bit-level manipulation, useful in low-level programming, embedded systems, and optimization.

Bash

Bash Parameter Expansion

Advanced string manipulation techniques in Bash using parameter expansion for substring extraction, default values, and string transformations

Bash

Bash File Globbing

Use wildcard patterns to match multiple files quickly and perform batch operations in directories

Bash

Bash Command Substitution

Capture command output as a variable or argument using $() or backticks, enabling dynamic command execution and processing

Ansible

Ansible Vault

Secure method for encrypting sensitive data like passwords and keys in Ansible playbooks, ensuring confidential information remains protected during automation.

Ansible

Ansible Loops

Iterate through lists, dictionaries, and complex data structures using loop constructs in Ansible playbooks to perform repetitive tasks efficiently.

Ansible

Ansible Handlers

Handlers are special tasks that only run when triggered by other tasks, typically used for service restarts or configuration changes.

Ansible

Ansible Facts

Automatically gathered system information about remote hosts that can be used for conditional task execution and dynamic configuration.

Ansible

Ansible Blocks

Blocks in Ansible allow grouping of tasks with shared error handling, allowing you to apply common parameters and manage task execution flow.

Angular

Angular ViewChild Decorator

A decorator that allows direct access to child components, DOM elements, or directives within a component's TypeScript class.

Angular

Angular Directives

Directives extend HTML with custom attributes and elements, allowing dynamic manipulation of DOM and component behavior.

Angular

Angular Dependency Injection

A core design pattern in Angular that allows classes to receive dependencies from external sources instead of creating them internally, promoting loose coupling and easier testing.

Angular

Angular Async Pipe

A powerful pipe in Angular that automatically subscribes and unsubscribes from Observables, simplifying data streaming and preventing memory leaks.
