Well, we have a confession: The man who blew up Wall Street.
How Michael Osinski Helped Build the Bomb That Blew Up Wall Street — New York Magazine .
Good read. A little bit of code, a few interesting ideas, expanded upon over a few decades, and *bam* he causes the entire economy to melt down. His great ideas, done in a conservative fashion worked, but when turned out willy nilly for everyone, caused a few years of over affordable credit, driving up housing prices and the stock market, until it collapsed.
Well worth your time to read!
