Basics of JSON data format

This article is an introduction to Javascript Object Notation or JSON for short. JSON is an open standard data-interchange format for transmitting data objects in the form of key-value pairs. JSON data is stored in .json files.

Contents:Basic SyntaxData TypesJSON SchemaDecoding JSONEncoding JSONApplicationsBasic Syntax

Although JSON is referred to as Javascript Object Notation, it is language independent, meaning many modern languages have libraries or classes to decode or encode data i...

Supervised, Unsupervised and Semi-Supervised Learning

In this article, we will learn more about the differences between Supervised, Unsupervised and Semi-Supervised Learning.

Table of contentsSupervised learningUnsupervised learningSemi-Supervised learningSummary

In machine learning, the tasks are broadly categorized into supervised and unsupervised learning. Semi-supervised learning falls between supervised and unsupervised learning. Let us understand what these terms mean.

Supervised learning

In supervised learning, we have a basic idea b...

stat command in Linux

In this article, we have discussed the stat command in Linux which is used to display information regarding files and file systems in Linux.

Table of contents.Introduction.Syntax.Commands.Summary.References.Introduction.

The stat command is used to print out the status of Linux files, directories and file systems.

Unlike ls command, stat prints out a lot of information regarding files, directories and file systems such as their sizes, blocks, inodes, permissions, timestamps for modificat...

Interprocess Communication: Mapped memory

Interprocess communication involves processes communicating with each other in this article we cover mapped memory and how it aids in this communication.
