       | This isn't as "CPU-based" as I had hoped, just metaphorically

       | level storage for items that are needed frequently, an Efficiency
       | Zone, with high-density racks for low-frequency items, and a
       | Shared Zone for mid-frequency items and overflow. The simulation
       | showed that this idea worked best, but the paper doesn't
       | investigate why.

         | No issue with your analysis, but it's a bit odd to say the
         | "idea of Performance and Efficiency cores" is from the Core i5.
         | 
         | First, the i5 is a tier in Intel's product stack and doesn't
         | refer to any specific generation. Core iX series processors
         | have existed since 2009 and have started using (general
         | purpose) heterogeneous cores only fairly recently (2020).
         | 
         | Second, I think most would credit ARM's big.LITTLE tech
         | (introduced in 2011) for the increase in popularity of these
         | types of heterogeneous (general purpose) cores on modern SoCs.

           | segmenting warehouse spaces into specialized zones
           | 
           | also jesus christ who cares - it's just a metaphor not stolen
           | valor.

       | Many years ago I operated the largest nationwide online DVD
       | rental business in my country. Our warehousing evolved from
       | alphabetical to numerical, with layout changes along the way.
       | Eventually we handed the rearchiving of DVDs to the database
       | itself and allowed it to allocate blocks of scanned in DVDs that
       | were being returned. New content also was allocated by this
       | system.
       | 
       | It was incredibly fun seeing things like cached new releases
       | going straight to dispatch rather than going into the warehouse.
       | Blocks of returning stock would be allocated to warehouse
       | sections that had gaps that had the physical size of the block of
       | DVDs that were being checked in.
       | 
       | Obviously, those empty areas were most commonly rotating stock,
       | so over time the warehouse would become more active in areas,
       | requiring a reallocation of stock to allow walking lanes for
       | picking staff to not become congested. Fun times and all done on
       | early Dell AXIMs with upgraded batteries, red laser scanners, and
       | this new thing called wifi.
