Today’s programmer of the day is Yukihiro Matsumoto aka Matz! <3
Matz is the creator and chief designer of the Ruby programming language and it’s reference implementation MRI (Matz Ruby Interpreter).
Matz says he created Ruby to make programmers happy, and designed it to be expressive. He is a famously nice guy, so much so that the Ruby community has adopted the saying MINSWAN, or: Matz Is Nice So We Are Nice.
Here is a great keynote Matz gave in 2008 about Ruby and why he created it.
