NASA's Sound Suppression Water System
If you’ve ever watched a rocket launch, you’ve probably noticed the billowing clouds around the launch pad during lift-off. What you’re seeing is not actually the rocket’s exhaust but the result of a launch pad and vehicle protection system known in NASA parlance as the Sound Suppression Water System. Exhaust gases from a rocket typically exit at a pressure higher than the ambient atmosphere, which generates shock waves and lots of turbulent mixing between the exhaust and the air. Put differently, launch ignition is incredibly loud, loud enough to cause structural damage to the launchpad and, via reflection, the vehicle and its contents. To mitigate this problem, launch operators use a massive water injection system that pours about 3.5 times as much water as rocket propellant per second. This significantly reduces the noise levels on the launchpad and vehicle and also helps protect the infrastructure from heat damage.

Apple Stole My Music. No, Seriously.
some amazingly terrible product decisions here. Deleting local copies of unreleased WAV files -- on the assumption that the user will simply listen to them streamed down from Apple Music -- that is astonishingly bad, and it's amazing they didn't consider the "freelance composer" use case at all.
