I used to work in grocery store. Bar codes are used there. Now I hear that they need to move to QR codes. But, my understanding it's going to cost billions to do this. I almost feel they won't make the change until bar codes simply stop working. 😢

Doesn't SOS stand for Save our Souls.

I tried but you lost me at hello 😇
@cosmicdebris2223 Says:
couldn't resist it so I scanned the examples at 12:05 ...result? Version 1 "I'm the OG" and version 2 "I'm a bog standard QR code" ... funny. 3:40 when I was a kid over 60 years ago we were told that SOS stood for Save Our Souls. Has this been bogus inf. all that time?
@avatarcowboy2435 Says:
I was part of an imaging and print quality design group in a color printer and copier company. 20+ years ago we created color codes that could be printed on a page. These codes contained information about how we created the print or copy as well as other useful information about the state of the machine at the time the page was created. When scanning a print or copy to analyze image quality characteristics, the information color code was also scanned and decoded. While up to 16.7 million colors are typically available, the practical number that could be used for multicolor QR codes is much a smaller number. However, when compared to a binary, i.e. 2 color format, a multicolor format could provide much higher information density.

I am nearly blind and depend on audio for information. I did not get a chance to understand much of the information that was in Japanese. Very frustrating.

Most people watch YouTube on their mobile devices... so how do we scan the QR code on our mobile devices?
@hareshkanna1626 Says:
I tried each of the qr codes in this frame 28:23 ,they all decoded same thing
@megavinx Says:
I first noticed the qr codes when I was working in Japan and I thought these were strange looking code. But when I used my phone to scan it, it goes directly to a website which I found it fascinating! To whoever invented this... ingenious!
@papabear9715 Says:
I thought "S.O.S" stood for Save Our Ship.
@coenraadloubser5768 Says:
The first QR code contains some AI generated text about the history of QR Codes. The second one contains an exe: Snake.exe .. but it won't run on Wine or Dosbox. The Version 1 QR Code says "I'm the OG". Version 2 is "a bog-standard QR code". Couldn't scan the rest and have work to do now........ 😀
@coenraadloubser5768 Says:
12:16 Come on you lazy bum, you could've actually put the Apollo 11 data in the codes..... 😅

GO... Crazy With the game of QR.
@kdfox2007 Says:
This video reminds me of a Connections episode with James Burke in the 1980’s plus an advanced math class. Very, Very well done.
@yashvantB Says:
While paying, I noticed that scanning QR codes at odd angles still worked, and I realized that vendor-specific details are stored in the lower right corner. Today, this video confirmed that my assumption was correct. Superb explanation as always, happy to learn about QR and its inventors.

10:30 presents a go game with an impossible position. the black stone in the middle of the bottom third line should been... oh wow there are many mistakes in this clip.

What a totally fabulous and enlightening video. Thank you.
@streiger108 Says:
These might be stupid questions, but why not encode the bits linearly instead of across two columns? Also, what happens if you want to encode more data? The url you encoded was short, but how do longer URLs work?
