Design Pattern : Introduction

In our day to day lives as software engineers we encounter recurring conceptual problems, there may be many ways to solve that problem, but How do I go about finding the best  way to tackle it? The answer is Design Patterns. Design patterns are solutions to recurring problems, these are widely accepted solutions by software […]

MHz GHz zzzzz…..

Whenever we discuss about any system be it a laptop, a phone, a desktop we are always concerned  about the processor. How many GigaHertz is the processor? Which is the latest in the market? The higher the better?…  But what really is MHz and Ghz? And why is it so important? HERTZ Hz in MHz […]

Part I : RESTful API

In this post I will be covering: What is a Restful API Methods / verbs Implementing API calls API’s To explain API, i’ll use the Waiter analogy. Once you go to the restaurant and you are seated, the waiter comes to you with a Menu, Menu is a list of stuff you can order. So […]

Part I: How efficient is your code?

Given a problem statement, we tend to find out ways to solve the problem – Our focus is understanding the problem statement and solving it. But are we solving the problem Efficiently is my question. As Software Engineers we don’t just write code, we write an efficient code. When I say “Efficient” I not only […]

Structural Design Pattern: Decorators

As per Wiki structural design patterns are design patterns that ease the design by identifying a simple way to realize relationships among entities. In this post we will discuss Decorators. Decorators, add additional features to object dynamically without using sub-classing Let’s consider an analogy here, our bakery needs some automation, everyday I spend few hours setting up appliances like pre-heating […]

Creational Design Pattern: Prototype

Prototype Pattern is another creational pattern that clones objects as per the prototype. Basically it lets you make copies of existing object. Prototyping is important when we creating many similar objects, but this process can be expensive so the solution is ‘Cloning’ instead of making individual objects. Lets consider an analogy here, we are mass […]
