"And now we have a working QE code. Try it out!" He says to me while I'm watching on my phone, and thus can't turn the camera on the screen...ffs

Who all tried to scan each and every QR Code in the video? 😅

[@NoobeeGaming]

I'd always assumed they were somehow related to QR decompositions

[@RagsRiches-d2o]

didn't bud few minutes a go changed the thumbnail?

Bit weird to me to use an image to represent an image. It's basically a tool to convert a picture to binary. To then encode that binary into an image sounds wasteful

[@sanjeevgrampurohit4374]

Was looking for this. Also, can't medical images of patients simply be transferred to radiologists as image files (DICOM perhaps)?

I bet you that someone will scan every qr code in this video😂

[@chaosjacky]

I'm pretty sure 99% of viewers watched that math segment without understanding a thing but kept watching

[@jeffs1571]

Wow man you're so cool

[@Wildflwers]

Only ogs will know the thumbnail was changed

Been working with barcodes in a nuclear research facility. Had to have those on barrels in toxic rooms so people can scan and get out asap. Learned most of the info back then. They're really neat, but somewhat limited.
