[HDGEM] A single decision by a single developer.

August 2012, an automated trading platform, some testing code that sneaked into production servers and the "one line of bad coding" - a feature flag that was used to activate that code was re-purposed for another feature. When that flag was switched on, one server still had the old test code. That caused the trading algorithm to go haywire and issue a millions of trade instructions in mere 45 minutes, causing the company a $440 million loss, from which it never fully recovered.
