Amazon’s $23M book about flies (2011)
I talked once to a dev who does this sort of thing. Its common. It's also interesting to consider what options folks have for quick, easy short-circuit algorithms. Any ideas for clever hacks to prevent the totally absurd with minimal state retention needed?<p>When I started talking about moving averages and trend related metrics, the person I was talking to commented that they where doing this in Excel or an Access database and wouldn't know how to handle that with say 250,000 books they might know or care about... then again maybe the downside of having one random crazy price is not even worth a cheap hack.
