How do square barcodes work? How many combinations are possible?

As always, liking, subscribing, and commenting are a huge help.

[@kirit2909]

Damn, scanning the QR at the beginning of the video takes you to: kzbin.info/www/bejne/moLaZapvjMyLmbM Which is a really cute puppy video, loved it

[@H3Vtux]

15 years later I'm still falling for this....

[@brentambrielcabigas1086]

Cute puppy video gave me flashbacks KZbin was Rick rolled and my theory states that KZbin was so mad that they removed the dislike count

[@antnoknee]

I am going to click it 🤚😐 ( that is the thing that solders do) Edit:well what can I say I enjoyed the song a little

[@mogusX37dot]

i memorised the link nice try

[@PhukPKummings]

I've always wondered this but never took the time to look it up but I'm glad I do now!

[@stachowi]

YES!!! I'm working on a QR project right now and this was super informative.

I really love this channel!

[@guesswhat8864]

I was googling about this just a few days ago!!! Thanks man

[@nxt6341]

man, your videos are really informative, and I thought it was pretty cool you showing yourself in the video :)

[@rossraymond813]

Thanks!

[@brentambrielcabigas1086]

Um What?

[@recaibey]

@@brentambrielcabigas1086 Lemme guess, You've seen most different comment section.

[@sharankhosla6666]

Wonderful Work👏🏻👏🏻

[@Populous3Tutorials]

just think about this: each human alive could create quadrillions of codes per second, all at once, and it would still last megazillions of years before we ran out of codes

[@Blaze_0101]

Thats cool!

[@bavajivenkatin976]

Nyc explanation bro

[@macchau6859]

Nicely explained

[@CivilEngineeringvideos]

l love your content

[@-wahatech3468]

Thanks a lot

[@user-fz4jr6tv5x]

i guess they can represent rick and roll video file in ascii or 1-0

[@AnupSingh-kw3ww]

Don't worry the universe will never run out of QR codes.

[@nassimdz]

What is the probability that two code qr are identical?

[@H3Vtux]

1/whichever number I showed being the amount of combinations. So for a 21X21 it's 1/the number at 1:05 though methods are taken to prevent them from being the same, so in reality the probability is even lower, down to essentially 0.

[@riex1044]

Why 1 byte = 8 bit only ?

[@abdullahalam3805]

I think you have to teach programming like C language

[@Salma-og5to]

hey can anyone please explain the ascii concept?? thank uu !

[@s-w]

Look it up

[@eduentmotiv3496]

Match QR code with any other QR code

[@erfanzr6422]

How simple you tell super complicated (binary+math) Things ! Your channel is “simplicated” .

[@anubhabmukherjee8486]

Please explain why your using 2 as a base to calculate the total number of possible combinations at 00:57 of your video...didn't get that.!!

[@H3Vtux]

Because anything with two values is base 2, and in this case either square can be black, or white. If each square could be black/white/red/green/yellow/orange/brown/grey/blue/purple then base ten would be the correct choice because there are ten "states" that each square can be in. For this each square only has two states, so it's essentially a really long base 2 number.

[@karanrajak_19]

Because there is only two characters 1 or 0 Black = 1 White = 0

[@deinemama6303]

Here is also a very interesting video about this topic: kzbin.info/www/bejne/e6naooGomtSWpsk

[@olgatihonova1775]

😝😝✊✊😠😠😠

[@ayaanyasser1677]

nvm this is outa my league of understanding

[@binarywizard69420]

Title:How many possible combinations? Doesn't tell the actual nos. Of combination

[@EricBussman]

Uhhh yeah he did. He clearly showed the calculation of the number of combinations. Did you even watch the video?
