One of the key features of the QT framework is providing communication between objects via signals and slots. For QT developers, this is a very convenient and organic way to do things, but the nature of the feature does not allow to communicate between objects located in different address spaces. Therefore, the need arose to create a library that would allow establishing communication between objects located in different processes in a way when the user just needs to connect signals and slots of these objects.
The results of this effort I called the QRpc library, and here is how it is applied and built.

There’s a lot of IoT SCADA solutions for factories and other manufacturing needs. Yet, there are cases (and quite a lot), when you need to develop your own SCADA system to cover specific needs of your project.
We often use awesome Qt framework for implementing complex IoT solutions. For a bunch SCADA and SCADA-like projects, we came across the need for quick tool for developing device dashboards. That’s why we developed super lightweight unofficial Qt library. The library is open source, customizable, and free to use under MIT license. We also share a small set of developed widgets.
Enjoy and use Qt ;)
README: This library is created for desktop, mobile, and embedded projects developed on Qt. To use it, you should know Qt/ C++ and QML.
For example, well-known companies including LinkedIn change their server-side code to Node.js.
Currently, it is used by 94.5% of all websites and help web developers to make web pages dynamic and interactive by implementing custom client-side scripts.
Note* Scripting language used to create and control dynamic web components (things like photo slideshows, animated graphics, and interactive forms).
In order to provide the best condition to developers, the framework gives the best conditions for combining JavaScript with HTML and CSS and certainly be your choice for the next project.
It is an open-source front end javascript framework used for building robust web applications.
It is one of the most downloaded, cross-platform runtime environments for executing JavaScript code.
Extending the same knowledge, the emergence of Node.js has enabled front-end coders (who used to make use of JavaScript only) to adopt back-end coding equally well.
Node.js is a fast and scalable option for medium sized to large network applications based on event-driven non-blocking input/output model that makes use of synchronous programming.
There is always some kind of generic implementation that is unique to the framework for every Node.js function which would then require the user to follow the lead of the framework by adding more codes to define its use cases.
Set of routing libraries, powerful collection of frameworks and focus on high performance, a multitude of easy to use HTTP utility methods, middleware and functions enable developers to easily write robust APIs.
Writing a simple program to print “Hello World”
const express = require('express') const app = express() const port = 3000 app.get('/', (req, res) => res.send('Hello World!'))
