What is Hashing | Why we need Hashing | [Data structures and Algorithm]
Просмотров 7192 года назад
Hashing is a technique to convert a given object/value into another near unique value. This helps in improving the efficiency of a lookup operation by mapping the actual value to a specific key. This video explains the technique of hashing using simple examples.

Composition over Inheritance [Object Oriented Programming]
Просмотров 4,2 тыс.2 года назад
Prefer Composition over Inheritance. With composition, it's easy to change behaviour on the fly with Dependency Injection / Setters. Inheritance is more rigid as most languages do not allow you to derive from more than one type. This video talks about what is Composition and why to prefer it over Inheritance.

What is Service Mesh? 💡 [Microservices | System Design]
Просмотров 1,3 тыс.2 года назад
A service mesh is a dedicated infrastructure layer built right into an app that document how well (or not) different parts of an app interact, so it becomes easier to optimize communication and avoid downtime as an app grows. This video talks about what are th e challenges in service to service communication in microservices design pattern and how service mesh manages those complexities. Refere...

What is Time Complexity? ⏰ (Data Structures and Algorithms)
Просмотров 3492 года назад
Time Complexity is a technique used by Computer scientists to measure the efficiency of an algorithm. It is usually represented by Big'O Notation. Beginners usually feel that this is a complex concept to understand. In this video, I try to explain this concept as simple as possible.

What is Circuit Breaker? [Resilient System Design | Microservices]
Просмотров 5462 года назад
Circuit breaker in electrical domain, a device that controls the flow of electricity into the appliance. It protects the device from unusual flow of electricity. In this video, I am explaining, how the same pattern can be applied to microservices design.
