Quick Sort outperforms Heap Sort despite similar O(N log N) time complexity due to better cache efficiency, smaller overhead & adaptive pivoting. Quick Sort: O(N log N), O(log N) space. Heap Sort: O(N log N), O(1) space but slower.

The __new__ method in Python creates & returns a new instance of a class. Used for singleton patterns, caching, memory management & more!

Load balancing distributes network traffic across multiple servers, ensuring smooth user access. There are two types: Layer 4 (network-level) and Layer 7 (application-specific), each with its own strengths and use cases.

Caching strategies for scalable systems, including Cache-Aside, Read-Through, Write-Through, and more.

Edgar F. Codd's relational model revolutionized data management, leading to the development of SQL, which powers most modern databases today.
