My week is going well, I was watching a Veritasium video about QR codes. About 20 minutes in he talks about some sort of complicated maths that I do not understand but the idea behind QR codes is cool. It actually got me thinking about how archive.org went down and how cool it would be to have a code that holds lots of information for preservation. I was thinking each square could represent a single character based on its hex colour once all characters are used other hex colours could be used to store combinations of characters. Idk how practical it would be but if the size of the .png/.webp size can get smaller than the size of the information stored it would be really useful for data preservation.
I watched that video and I was thinking about how the regular person without math background would think that is extremely confusing.
All I really understood was it starts in the bottom right going up and changes direction whenever it reaches the end in a snake like pattern. I think from doing that but with every square being a hex/RGB pixel the amount of information that could be stored could be huge. The video also mentioned if you made a random pattern its likely it would mean nothing. Using some of the patterns that don't translate to anything and having them mean their own thing could add even more information. I might be getting ahead of myself but this could be useful for stuff like peertube storing videos using less storage and then decoding them. The main problem is I would need to find someone who knows how to make qr hexcode/hybrid a reality since I have no idea how I would go about it.
