Once upon a time, like around 1989 in the days of x86 processors, memory optimizers were essential utilities. I recall using Quarterdeck’s QEMM. I hadn't thought about memops since. Until today.

A laugh-out-loud moment from the Mac App Store, a customer review of the OSX app Memory Clean:

Free memory is like Inactive memory, it takes the same electricity to run, it's just as consumable by programs, but it has one difference. Free memory will never lift a finger to help the OS with file acceleration. If inactive memory is the roommate that bounces between part-time jobs, free memory is the one that refuses to ever get a job, and eats all your Cheez Curls.

On the trip down memory lane I also re-discovered a long-lost gem, the MS-DOS replacement DR-DOS.
