Why so many ads
@vincenzoditerlizzi4379 Says:
There's a bit of QR codes in this advertisement
@eisbar7681 Says:
placing an ad every two minutes is just rude
@scotth9990 Says:
I'm getting one or two ads every 100 or so seconds. This is terrible.
@_dheyaalomaisi9494 Says:
what is the problem with all of these ads?
@ekaksana Says:
The quantity of adds...
@MitarbeiterMathlabs_1 Says:
In a NAS there’s also error correction. Is the system of RAID the same as with QR Codes?
@MitarbeiterMathlabs_1 Says:
22:19 Bro, if you send me this I wouldn’t understand it at all 😂
@officialgoogolplexandfour10104 Says:
why ads appear when i watch this video?
@Acheron2Liam Says:
mattKC mentioned
@tacticstories7159 Says:
The number of ads in this video are insane. It's one ad per minute!!!
@DanielRyan-n8t Says:
Lots of good information if you can ignore the 30 ads to get through the video
@reelshorts4908 Says:
To much add😢
@DJNoxious32 Says:
I figured SOS always stood for Send Out Somebody...
@eric-janhted9346 Says:
I always thought QR codes were much simpler. Wow, much thought went into them.
@JBentley893 Says:
8 ad breaks and only 10 minutes in. Do I really want 16 more interruptions to learn about qr codes?
@karamelflan Says:
that was a great video! I myself still don't understand polynomials; it was my least favorite and still confusing mathematics, but I get the logic and reason of creation of the error correction system.
@NathanZhu-n1h Says:
Does this mean if I draw a random sequence it will pop out a product?
@Oitausizgrpd Says:
Hey!! So, I have a good idea!!! Why not add +color layering to QR codes in the Z direction by using CYM additive color rules to add either; Hamming distance, for error correction, *or to triple data storage for the same area! EXAMPLE BELOW 👇 If the layering is represented; -bottom: magenta, -middle: yellow, and -top: cyan. __Rules for Combined colors__; all 0s/no color = white (W) magenta+ yellow= orange (ϴ), yellow + cyan. = green (G) cyan+ magenta. = purple (P) mag+yellow+cyan= black (B) ⁞⁞⁞⁞example data⁞⁞⁞⁞ Magenta = 101 110 001 ‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥(M0M MM0 00M) Yellow = 101 001 010 ‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥(Y0Y 00Y 0Y0) Cyan = 100 100 110 ‥‥‥‥‥‥‥‥‥‥‥‥‥‥‥(C00 C00 CC0) Output = (BWϴ PMY CGM) 🖤🤍🧡 💜🩷💛 🩵💚🩷 This would layer the three QR codes data in a readable way... and would look way prettier than the plain B+W codes. You're welcome 🤗😁
@yuvrajverma629 Says:
bro how many ada have the put on this video. Chill out
@MasterShigley Says:
Beautiful video. Would have finished it if it did not pause for ads every 2 minutes.
@utarefson9 Says:
33:58 "You have scanned countless QR codes" Bro it's 2026 and i've never seen any outside the internet
@elihatton2628 Says:
did anyone else get ads literally every 15 seconds 😭 this is getting egregious
@smileyfase-z7r Says:
too many adds every minute
@SolverCore Says:
13:03 watch the video with a camera. also the ad saved me. "Im the OG" "I'm the Bog-Standard QR code"
@LucasWilber-i2c Says:
This multi-dimensional and polynomial with this Reed-Solomon stuff can be mind-crushing, is definitely not a efficient try to do it on pen and paper especially for large sets. And yet phones can still recognize QR codes just fine with this crazy stuff with this ubiquitous Reed-Solomon code. Amazing!
@RezNoMore Says:
Myself, once thought that , can images be stored into QR codes , using colour code per pixle but that results a blury image . Guess why?❤
@drift_0712 Says:
13:16 I swear did anyone notice that if you scan the QR code you get rickrolled…

Did you copy mattbatwings or did Mattbatwings copy you....or are you the same guy :).... loved the video

@QuotePilgrim Says:
...and this video uses the incorrect SOS signal. The thing about SOS is that it is NOT the letters S, O, and S. It is not ••• ——— •••, but rather •••———•••. Can you tell the difference? There are no spaces in between the dits and the dahs. SOS is just a mnemonic to remember the code. It might as well be EEETTTEEE, IWB, VZE... because once you remove the spaces between letters, like you are supposed to do with SOS, they all become the same exact signal. The incorrect SOS is so ubiquitous, unfortunately, that no online Morse code encoder/decoder (that I could find) can generate nor decode it. If you go on English language Wikipedia, at least the audio at the top of the article is correct, but then it uses the wrong code for the light-based version.
@hanzo1010 Says:
how does all these calculation are being made in an instant. even managing error, alignment and orientation ??
@300pingdog Says:
i honestly think that you could have scanned it with your phone

Flaming hot mountain dew and sour patch oreos is crazy
@ArthurTheSecond Says:
Thanks for the Rick Roll 😂
@ayaankhizar-q6n Says:
you should watch matbatwings qr code video he realy deserve a appriciation from you guys
@jerryberry20 Says:
what about Save Our Souls?
@hhhhhhhhh7yhg Says:
1:00 HAMILTON REFERENCE!
@NeverlandSystemZor Says:
What is most amazing is that the creator of the modern QR code made it accessible to ANYONE rather than a closed-source sort of thing. He WANTED it to be useful and free to the world. Pretty cool.
@plrc4593 Says:
10:27 - these folks don't know how to play go.
@Progamere95 Says:
13:03 That qr code lead to never gonna give you up, basically rick roll
@boondaas Says:
SOS does actually mean something: "Save Our Souls" (thats not my myth its the truth)
@CheeZhiXuanEndeavourps Says:
18:16 ad skip

The legend made QR codes a public good. Remember barcodes? Those billions of fractions of pennies keep stacking up. And for what? A bar. Code.

How many go players had a stroke watching this?
