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 def…

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 i…

OP is being respectful and merely points out an issue: the codes generated don’t work with some devices. If you want a code that works with everything, you can’t do too much customization.

It’s a very okay thing to point out and there isn’t much negativity in it. I agree that we should support projects like this, but being dismissive of real issues is not the way.

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.

Thanks for trying it out! I definitely agree, the fancier it gets the harder it is to scan so these should not be used for real world stuff where reliability is important.

I basically only tested these on my own phone, a pixel 7 with default camera app, so I'm not surprised people with different hardware/software are getting varied results. I think I might try to automate testing using different scanners if I can figure that out.

I tested it with my phone and got similar results: I got only 9 out of the 21 QR codes to work. I don't know why you think such a finding should not be mentioned here.

If you want to use something for production, you shouldn’t only test on the latest stuff you personally have at home but on the crappiest stuff you reasonably expect users to have. Otherwise, you get websites that lag and spin up the fans on everybody’s laptops while the developer is happy on his workstation with 32 cores and a gaming GPU.

How have I never heard of pngpaste before?

Agree, but OP should not then "not recommend" and it shouldn't be top comment dissuading others from seeing this AWESOME project.

I think it should be mentioned but without the "so I'd recommend against using", because that's wrong. Also, specify OS, surface, time, etc for better test!
