Can someone explain the error correction a bit more? How exactly is it that you're blanking out 1/3 of the code and it still works? Does it matter which bits

Can someone explain the error correction a bit more? How exactly is it that you're blanking out 1/3 of the code and it still works? Does it matter which bits you disrupt? Couldn't your design, if comprised black and white squares, inadvertently BE readable QR data that screws up your message?

- darklajid 15y agoSomewhat off-topic, but this reminds me of those 'why math is gibberish to laymen' posts a couple of weeks ago. I know my math background sucks _and_ I'm stuck with the German version (i.e. the field suffers much more from being localized than CS. There are lunatics that try to create German words for everything from motherboard to stack - but I think we locked all of them up by now). This article is unreadable without clicking on every other link in there and starting from scratch for me. Embarrassing.
