An Engineer's love song

I was alone and all was dark, Beneath me and above
My life was full of volts and amps, But not the spark of love

But now that you are here with me, My heart is overjoyed
You turn the square of my heart, Into a sinusoid

You load things from my memory, Onto my system's bus
My life was once assembly code, Now it's C++

I love the way you solder things, My circuits you can fix
The voltage across your diode is, much more than just point six

With your amps and resistors, You have built my integrator
I cannot survive without you, You are my function generator

You have charged my life,increased gain, And made my maths discreet
And now I'll end my poem here, Control, Alt, and Delete
