The web is basically operational using HTTP requests and responses. In this mechanism, the client always initiates the connection. There is a timeout period after which the server discards the connection. Once discarded, the client must initiate a new connection. This is OK with normal web applications, but for real-time communication, this is not enough. A system called HTTP-long polling was…
We can easily write apps that communicate with IoT devices when we combine MQTT with Windows App Development like Delphi. Follow along with us now as Bruno Mileto tells us how to do it.
IoT – the unseen world
Internet of Things, or IoT, is a concept that defines…
Low code app development is increasingly popular today, and for good reason: it speaks to the demand for software paired with the difficulty of creating it. In many ways, Delphi led the low code revolution: RAD, where you build software by connecting components in a visual…
In the recent Data ETL focused TCoffeeAndCode episode there was some excellent discussion around the use of FireDAC to extract and manipulate data in various ways. In this article, you’ll get through what Data ETL is, what is LiveBindings, using Live Bindings with an IDE software , using LiveBindings with custom binding expressions and many more.

In early 2015, HTTP/2 was introduced as the new standard by IESG. This standard makes your application faster, simpler, and more robust. In this article, we take you through the differences between HTTP/1 and HTTP/2, the benefits, using HTTP/1 and HTTP/2 with windows…
WebSockets are gaining traction as more browsers, including those for mobile devices, support them. This article introduces WebSockets briefly and creates a chat app using a Websockets component for Delphi, a Windows Program Development, provided by Delphi component provider…
What are the fastest data encoding and decoding methods? Can we use shifting to encode or decode data or files? How can we make use of the C++ compiler? Can we use shifting on strings or binary data? Should we? We’ll do our best to answer all of these questions.
Bits and bitwise operations
Thebitis the most basic unit of information in computing and digital communications.
In this article, you’ll learn what scientific computing is, why we use python for scientific computing, and how to use python windows GUI builder with scientific computing libraries, the results, and many more.

In this post, we’re going to be covering tips and tricks on how you can optimize your c++ software projects to compile as fast as possible. While we’ll definitely be spending some time looking at optimizations geared for use with TwineCompile, some of these tricks apply…
The AI API “Fast Style” is a form of graphical style transfer which uses a neural network to combine the artistic styles of one image with another to render a new unique image. You can think of it as taking a photograph and combining it with a Manet painting to produce a unique photo after the style of Manet.
To make art, we will use the help of DeepAi.org a platform that you can…
