A talk by bunnie introducing their Love to Code program, a program for teaching children (adults too) to code using cheap papercraft-inspired devices and tools. The argument is that the diversity problem that exists in coding can maybe be fixed by starting at the earliest stages, i.e., starting with children.
From a technical perspective they had to solve some interesting problems to make the technology fast, cheap and usable. In particular, they have a pretty awesome technique using sound to upload code to the microcontrollers they use.
Takeaway: Pretty cool technology for a societally relevant goal. Check it out.
