Using the tools and methods that will be discussed later, you can check the protection of your own Unity game and learn how to protect it from hacking and theft of resources.

The history of one fakap Yandex.Navigator. In six acts with prologue and remorse

As I wrote the guitar tuner for iOS on Swift. And also a little about DSP, standing waves and how to achieve accuracy of ± 0.1Hz

In this article I will talk about how I had the idea to write my tuner and what it led to. I will also share my modest knowledge in the field of DSP (digital signal processing) obtained at the university, and how they helped me solve some problems. And of course, I will share the source code and the experience of programming on Swift that I gained during the implementation of this project.
