Very cool #introduction to #qr #codes https://typefully.com/DanHollick/qr-code.. Much #simpler than I thought they would be! I guess all a #vision #algorithm has to do is #detect the #patterns - and then it can go from there.
Just saw this #article about writing a #printer #driver in #javascript https://kubesail.com/blog/2022-02-01-pri.. I always wanted to play with a #thermal #printer but never had an excuse - but I just thought of one. I could really improve the #business #process of a family member by printing #qr #codes to help them #track #products and #parcels !
Looks like these #qr #codes everybody have been using are #vulnerable to #string #manipulation - pointing people to different #url #locations https://www.androidpolice.com/google-cam.. Apparently #hackers are already using this #vulnerability and the general #trusting nature of people to point them towards #phishing #domains https://www.pcmag.com/news/fbi-hackers-a..
#qr #codes are genuinely pretty cool: https://huonw.github.io/blog/2021/09/qr-.. At some point in the future I would like to play about with them properly, perhaps in the context of #humanoid #robotics where all other #factors such as #detection #accuracy can be ruled out when designing #behaviours !
