I disassembled my keyboard and found this. The USB connector has 5 pins. 4 of them are usual and go to the MCU, and the 5th pin goes to the chassis (metal casing of the keyboard).

But what's the purpose of that SS14 diode? Is it for ESD?

AI says complete nonsense, so I am asking real human beings for explanation. Help is appreciated.

C# is known for its boilerplate and verbosity. Most of the time, it's reasonable, and MS does a good thing by teaching you to follow the structure (so others can maintain your code, lol).

But sometimes you really want a simple IDisposable app, like university coursework or a small utility. In this case, people use Python. But now C# is a great candidate too!

Here's the code sample. It uses Avalonia, so it is cross-platform, and it uses no XAML for simplicity (my friends were surprised it's possible).

It has 3 NuGet references at the top, then here goes the class with AppBuilder, when we start an app, we:

1. Add a theme (optional, but it looks good)
2. Create a window object
3. Create a Label
4. Show the window we just created and run the app!

#:package Avalonia@*
#:package Avalonia.Desktop@*
#:package Avalonia.Themes.Simple@*

using Avalonia;
using Avalonia.Controls;

class MainClass {
    public static void Main(string[] args) {
        AppBuilder
            .Configure<Application>()
            .UsePlatformDetect()
            .Start(AppMain, args);
    }

    public static void AppMain(Application app, string[] args) {
        // Application needs a theme to render window content
        app.Styles.Add(new Avalonia.Themes.Simple.SimpleTheme());
        app.RequestedThemeVariant = Avalonia.Styling.ThemeVariant.Default; // Default, Dark, Light

        // Create window
        var win = new Window();
        win.Title = "Avalonia no XAML";
        win.Width = 800;
        win.Height = 600;

        var text = new Label();
        win.Content = text;

        text.Content = "Hello from C#!";
        text.HorizontalAlignment = Avalonia.Layout.HorizontalAlignment.Center;
        text.VerticalAlignment = Avalonia.Layout.VerticalAlignment.Center;
        text.FontSize = 72;

        win.Show();
        app.Run(win);
    }
}
