Write once, run on every boards: portable mruby

In embedded programming, the development environment and libraries we use to program are different depending on hardware. So, we have to make different programs for each hardware. Would not it be nice if CRuby works on Mac and Windows, even if the hardware is different, would the same mruby program run? I have a plan off platform to make one same Ruby code run on various microcontrollers. In this session, I will introduce an example of running Ruby code on several microcomputers.
