baocin··on Sod – An Embedded Computer Vision and Machine Learning Tiny C Library
"Q16.16" seems to refer to fixed floating point precision (https://en.wikipedia.org/wiki/Q_(number_format)). The parent comment is unhappy that SOD doesn't support floats with 16 integer bits and 16 fractional bits. I'm unsure why lack of support for 32 bit floats is such a problem considering that SOD is suppose to run on such resource constrained devices. Is there a particular domain where this is necessary?
baocin··on Virtual Reality Can Leave You with an Existential Hangover
Reminds me of a Reinhold Niebuhr quote: "God, grant me the serenity to accept the things I cannot change, Courage to change the things I can, And wisdom to know the difference."

You could try adding in some simple motion, like raising your hand, before the system would start listening for hot words. Maybe connect a cheap infrared sensor to GPIO and block its view so it only detects motion at or above certain height.
baocin··on Offline messaging app (that actually works)
Really curious on how this works, is it just bluetooth or something fancier like Google Tone[0]?
