There is an ancient and mysterious legend about public static constructor, called createShit. If anyone want's just to create an instance of Shit be aware of it! This is too obvious! just Implement static method with the exactly the same fields, and make constructor private. Don't write a shit!

Where does the data come from? Where does it go? Why isn't this an endless recursive loop? Why has this worked for three years?

what if that mysterious power change it to be not null !! It gonna be a holly object and You should not "new" it anymore ?! damn ... :)))

When scientists write code, sometimes it's not pretty. It's rather redacted ("thing" was not "thing" in the original). I especially love that the Bash part uses `` rather than $().
if(!Hardware::initialize()) {
Serial.println("Hardware initialization failed!");
for(;;){}
}
if(!UI.begin()) {
Serial.println("SSD1306 allocation failed");
for(;;){}
}
For is best ever, why even bother with While, or even Return... Source of code: https://github.com/MausTec/nogasm-wifi/blob/master/ESP32_WiFi.ino
