What it is

Chuck Moore, inventor of Forth, presents GreenArrays' 144-core asynchronous chip at Strange Loop 2013. He explains how idle cores draw almost no power and how tight code minimizes energy use.

Why Hacker News recommends it

It is the favorite recommendation for understanding Moore's minimalist, low-power multi-core designs and stack machines.
