This looks super cool but I could only get 10/21 to scan with the classic zxing scanner (>100M downloads), and 3 of those took a bunch of playing with camera angles and distance, so I'd recommend against using anything too fancy for real world barcodes.

Did anyone else just watch the Veritasium video

I always notice these patterns on HN. Always gives me dejavu and that feeling you get when you suddenly start encountering some new topic or word in suspiciously large amounts. Some big sciency/techy outlet puts something interesting out, and suddenly related topics start popping up everywhere else. I am guilty of a few of these myself.

Ah, yes. The classic “works on my device” argument.

Edit: from testing with zbarimg on my laptop: Basic, Camo, Neon (inverted), Glass, Blocks, Alien all seem to work reliably. Not sure what the problem is with some others, but maybe they’ll also work with some tweaking (Mondrian seems simple enough! maybe contrast issues?)

  wl-paste -t image/png | zbarimg -
  # macOS:
  pngpaste | zbarimg -
Edit 2: for codes that will definitely be scanned using a camera [1], some styles can work because phone camera isn’t perfect. E.g. if you slightly blur Dots, it works with zbarimg, which also means it would work if you slightly move around your phone.

[1]: Screenshots are used sometimes! E.g. for importing TOTP codes into a password manager, etc.

Interestingly enough, it didn't work well with my android. Only couple of them were scanned easily.

Precisely the OP.

More importantly it's sad and bad when a obvious negative comment is at the top of a front-page Show HN, that misrepresents and then deigns to provide recommendations against this nascent beautiful project that needs our support. Effectively shutting down the experience and enjoyment for incoming audience, and for the creator.

That is a very bad thing and should not be tolerated. Speak up against it.

This is awesome. Does anyone know if there is a library for the amazing optical codes that apple uses in its device transfer? I know they have a custom patent for it so I don't know if its something anyone has tried to recreated...

Do you have link for more info on optical codes?
