Lightning Talk – Michael King
summary
Shows concrete concurrency patterns and results: uses Ruby Thread and the Queue class for producer–consumer, demonstrates a Redis list with R push / L pop as a practical alternative, and models supply and demand in an "Economy Simulator 9000" that visualizes producers and consumers via what the transcript calls Ashen cable. Implements deadlock via the dining philosophers solved with a mutex, and measures a report generator of 100,000 rows, 5 columns where 10 threads win but hundreds of threads slow things down.
