I got a 7k bonus 20 years ago in the military. I seriously considered investing it in the Vangard total stock market index fund. In '04 it was trading at $54 per share, today $282. Had I invested that $7,000 I would have $365,555 today. Instead I “invested” it at the strip club because I was a young dumb E-3 in Pensacola and New Orleans was only a weekend pass away. Long story short, index funds are the way to go.
Great write up, now I have to google what a Meraenne Twister is. To use audio input noise as a random number gen I would just hook it up to a pressision digital db meter but I’m guessing the software implementation is a little more practical.
