Programmer Training Java Book

As the main author, I wrote the Java learning book called Programmer Training Java with another author.

The book introduces the basics of Java step-by-step, explains how to install JDK and create simple applets, and presents many examples, such as games, graphics programs, or modern information systems. It also contains advanced techniques, such as threads or the AWT.

The book was translated into multiple languages for the European market, its ISBN is 9783815813034, and it can be purchased at the link below.

VCV Rack Plugin for Using Formulas for Signal Generation

https://github.com/FrankBuss/FrankBussRackPlugin
A plugin written in C++ for VCV Rack is a platform-independent Eurorack emulator for Linux, Windows, and Mac. With it, a formula can be used to generate audio and control signals. The plugin is available for free from the official VCV Rack plugin site and is used to create patches and teach audio basics.
