The code used to generate the badges for Boilermake VII on January 24-26, 2020.
The QR codes were added in this iteration, and we removed the skill icons on the hacker badges. The QR codes functioned as expected in a vacuum, but in practice, there was a problem with glare and/or the color combination of the badge and code itself. A black QR code on a white background seems to work best or at lease something with high contrast. White and light purple seemed to not be a great mix...something to think about next time.
