The Internet of Things (IoT) has changed how we interact with devices and created new opportunities for businesses to gather and analyze data. However, this has created a demand for device−to−device communication that is seamless. This is where IoT Communications APIs come to play a major role in communication systems. IoT Communications APIs are a set of protocols and interfaces that allow IoT devices and platforms to communicate with one another. These APIs enable developers to create apps that interface with IoT devices over conventional web protocols including HTTP, MQTT, CoAP, and others. Internet of Things ... Read More
Blockchain is a newly popular technology widely used for the secure storage and sharing of information. It is a shared ledger that improves the ability to store data and information virtually about transactions or assets. Using this technology, the data assets can be stored digitally and the data will stay unaltered. Also, this works without any third−party intervention, which makes it even better in terms of security. And as the truth in the data is equal for all, it creates greater confidence and trust. This technology is widely used in the cryptographic industry as a public network and is very ... Read More
As a TypeScript developer, you may encounter situations where you need to add functionality to an existing class or interface without modifying its source code. In such cases, extension methods can come in handy. Extension methods allow you to add new methods to a class or interface, providing additional functionality to make your code more modular and easier to maintain. In this tutorial, we will see what extension methods are, how to declare and use them and provide examples of their use. What are Extension Methods? Extension methods are a powerful feature of TypeScript that allows you to add new ... Read More
In this era of the Internet of Things (IoT), where massive numbers of devices are interconnected and share data and information via the Internet. This enormous amount of data demands a system that can comprehend and manipulate the data to understand human behavior better. By analyzing the interaction of humans with IoT and observing the pattern in their behavior, a better and more profitable marketplace can be created by influencing the behavior of humans. The term “Internet of behavior” was first introduced by Gothe Nyman, who was working as a professor of psychology at the University of Helsinki. He ... Read More
The technology, Internet of Things (IoT) has completely changed how we work and live. It is a system of linked devices that collaborate to exchange information and carry out different functions. In the Internet of Things, communication is essential for allowing devices to connect, work together, and share information easily. The IoT ecosystem is built on the communication capabilities of gadgets, which allows for the development of intelligent, interconnected systems that can boost productivity, decision−making, and numerous operations. IoT systems with effective communication can be built to increase productivity, enhance decision−making, and automate operations in a variety of ... Read More
As a beginner-friendly programming language, TypeScript offers a variety of features to handle file operations effectively. Reading a file is a fundamental task that developers often encounter when working on projects. In this tutorial, we will explore different scenarios for reading files in TypeScript and provide clear explanations, along with syntax and code examples. Syntax const fileReader = new FileReader(); fileReader.onload = () => { const fileContent = fileReader.result as string; console.log(fileContent); }; The above is the syntax to read files in typescript. We create a new FileReader instance and use its onload ... Read More
In TypeScript, casting JSON objects inside classes can be a useful technique for mapping JSON data to structured TypeScript objects. By explicitly defining the types, we can ensure type safety and access the properties of the JSON object seamlessly. In this tutorial, we will guide you through the process of casting JSON objects inside TypeScript classes, enabling users to leverage the full power of TypeScript's static typing. Syntax Users can follow the syntax below to create a cast of a JSON object inside a TypeScript class. class MyClass { // Define class properties property1: ... Read More
I got started with Angular and TypeScript by realizing the importance of building scalable and maintainable web applications. Angular, as a web application framework, provided me with the tools I needed to build complex and dynamic applications with ease. TypeScript, as a statically typed superset of JavaScript, gave me the ability to write cleaner code, catch errors before runtime, and improve the overall scalability of my applications. In this tutorial, I will share my experience and guide you through creating a simple Angular application using TypeScript. We will cover the basics of Angular and TypeScript and provide a step-by-step guide ... Read More
First, let us understand what a crontab file is. Cron is a software utility that helps us schedule tasks on the Unix based systems. So basically, you’ll be able to periodically run assigned tasks, for example, automated system backups at the end of the day, to auto shutdown or set mode to DND at a particular time and more such features. These "tasks" in cron are usually defined in a file called crontab, which is basically a text file that contains the commands to be executed. Let us now learn how we can write these crontab files in Python using ... Read More
In the year 2015, Google unveiled Android Things, an embedded operating system platform. The phrase "Hardware based development" is used to describe Android Things. You may create IoT devices using the Android Things platform, which is an addition to the Android operating system. Since you are all familiar with Android Development, you can create Android Things using your current software skill set. To create IoT software quickly and efficiently, developers can use well−known tools like Android Studio and the Android SDK. They can then grow the hardware from a single prototype into mass production. Anyone can create commercial ... Read More
