Idea of Layer 4 and Layer 7 Load Balancing

We have covered the idea of Layer 4 and Layer 7 Load Balancing along with advantages and disadvantages. This is an important topic in System Design and is an effective Load Balancing technique.

Software Engineering

Idea of Consistency patterns in System Design

We have explained consistency pattern in System Design along with examples for different types like Eventual, Strong and Weak Consistency.

Software Engineering

Cloud Design Patterns

Cloud Design Pattern as defined by cloud computing experts are a general reusable solution to commonly occurring problems in cloud architecting. We have explained the different Cloud Design Patterns like Scale Up Pattern.

Software Engineering

Dynamic Memory Allocation in C++

Dynamic Memory Allocation in C++ is the process of allocating memory while a program is running or at run time rather than at compile time. C++ uses new and delete operator for dynamic allocation and freeing up of memory.

Problems on Binary Tree

Implement Binary Tree in Python

We have explored the strategy to implement Binary Tree in Python Programming Language with complete explanation and different operations like traversal, search and delete.

Software Engineering

2D arrays in C++ (2 ways)

We have discussed what are 2 Dimensional (2D) arrays and what are the different ways we can initialize them and how we can use them in C++.

System Design

Sidecar Design Pattern in System Design

We have explored Sidecar Design Pattern in System Design along with its advantages and disadvantages and a real System Design example using Sidecar Design Pattern.

Data Partitioning in System Design [Explained]

Data partitioning in simple terms is a method of distributing data across multiple tables, systems or sites to improve query processing performance and make the data more manageable. We have explored Data Partitioning in System Design in depth.

Software Engineering

Abstraction in C++ [Explained]

In this article, we have explained Abstraction in C++ in depth with different types of abstraction and C++ code examples.

Software Engineering

qsort: Sorting using stdlib.h in C [Explained with examples]

In this article, we have explained how to use qsort that is Sorting using stdlib.h in C. We have presented the use-case using code examples.

Software Engineering

Functions in Python [Explained with examples]

In this article, we have explored everything about functions in Python along with different types of functions that are available with Python code examples.

System Design

In memory Database [Explained]

In memory Database is a type of Database that is stored in main memory (instead of hard disk) which makes to significantly fast (100X improvement) with some limitations.

Software Engineering

Fixed width integer types (int8) in C++

C99 has defined a set of fixed-width integers that are guaranteed to have the same size on any architecture. These can be found in stdint.h header. This enables to use INT8 in C++.

System Design

System Design of Online Coding Judge (Competitive Programming Platform)

In this article, we have explored the system design of an online coding judge like HackerRank and CodeForces in depth and explored the best choices.

System Design

Memory Pool with C++ Implementation

Memory Pool is an optimization technique of allocating a specific amount of memory beforehand and handle all allocation and deallocation of memory from a concerned software system from this pre-allocated memory (which is known as Memory Pool).

Machine Learning (ML)

Back Propagation (Intuitively)

Back Propagation is one of the most important topics of Neural Net Training. It is the process of tuning the weights of neural network and is based on the rate of error of previous epoch.

System Design

System design of an URL Shortener (TinyURL or Bit.ly)

We have explained the ideas involved to design a system for URL shortening service which is scalable in the real environment.

Machine Learning (ML)

Stacking in Machine Learning

Stacking (a.k.a Stack Generalization) is an ensemble technique that uses meta-learning for generating predictions. We have explained stacking in Machine Learning (ML) in depth.

Software Engineering

Basics of Unordered multiset in C++

An unordered multiset is an unordered set (a set in which a key can be stored in any random order) that allows different elements to have equivalent values (allows duplicate items).

Software Engineering

Basic commands for using VIM editor like a Pro

In this guide, we have presented all basic commands that you will need to use VIM editor for doing all tasks efficiently. You will learn how to search for a word, how to replace the word, select, copy, paste, using various special features of VIM and much more.

Software Engineering

Create a custom UITableView in iOS using Swift

Create an iOS app which has a custom table view (UITableView) using MVC pattern using Swift.

Machine Learning (ML)

Concept Whitening in Machine Learning

Concept Whitening is a technique that can be used to find the inner functioning. The difference in its approach is that rather than searching for solutions in the trillions of trained parameters it tries to find answers by interpreting the networks.

Software Engineering

Immediate Functions in C++

Immediate functions or the functions which have consteval keyword before their return type has been introduced with the release of C++ 20 , consteval functions are the functions that must be evaluated at compile time to produce a constant.

Software Engineering

Explicit in C++

Explicit is a keyword in C++ which was introduced with C++ 11 this is used to cast a data type and also to change the by default implicit conversion in C++.
