hdhzy 8 years ago Excellent post! Months ago when I saw gopher QR code I was wondering how is it possible to encode picture like that but found nothing.
ingenieroariel 8 years ago It would be interesting to see traffic signs created this way. Readable both by humans and by machines from far away.
gabrielcsapo 8 years ago the article points to google code, is there another source? (gitlab, github, bitbucket, etc) niceperson 8 years ago AFAIK, no. AlbertoGP 8 years ago The code was exported to GitHub, to which I assume is the author's account (rsc):https://github.com/rsc/qrHowever, I'm not familiar with go and all I see there, is what looks like a plain QR encoding library.There is also code for the web server: https://github.com/rsc/swtch/blob/master/app/blog/qr.goAgain, I don't know how to dig further to find the source of the qrweb module.Any ideas?
