    Using 1,454,942 maximum size and minimum error correction QR codes in alphanumeric mode (byte mode is a lie) to store Base64-encoded binary data, you get roughly 4,687,823,124 bytes. 4.6 GB. If the cards are two-sided we get 9.2 GB.

    Minimum size of Windows 11 installer image seems to be 8 GB, so it checks out!

    KolibriOS, arguably the smallest modern GUI OS at 1.44MB, could be encoded on ~142 of them. I shouldn’t find that interesting but I do. MikeOS, which is an operating system used to teach about OS design, could fit on ~74.

    Making this a very dumb very impractical but nonetheless legitimately viable method for non-electromagnetic OS storage.

      Laminated paper qr codes for long-term storage could last centuries, possibly much more than an hard drive or a flash drive. That would probably outlive any computer it couls be used on, but it’s an interesting solution.

        Lol, i use qrencode for years in a tiny little function to display URL in the image viewer.

        Btw, Unixes used lf, Mac decided on cr, and that’s why MS used cr lf, for compatibility. Did i remember that right?

          I think I knew the answer to that last question about twenty years ago, but I can’t answer it with any guaranteed accuracy now, sorry.

          Actually … I thought it was carriage return (emulate sending the typewriter carriage back to the starting position), line feed (emulate typewriter moving paper up by one line). Or, to put it another way: ding!

        Maybe, but also I think I was looking at the raw ‘data bits’, not ‘binary’ data. It’s actually almost exactly 4GiB, even when dropping down to minimum error correction (1.7 GiB otherwise).

        (1454942×29531024÷1024÷10244.00

        Edit: So if alphanumeric mode could store lowercase letters, base64 would’ve stored more.

    The only thing that would top this would be using punch cards. I think that’d be around 58 million punch cards for Win11.

    I thought it would be cool to have qr-code stickers that when scanned would be an ebook.

    Sadly, they don’t hold enough data and I could not find any kind of compression that would help.

    I know it could be linked to a server, but then it’s reliant on an internet connection and for the server to be active.

      I love that idea. The first result I got on DDG says that QR codes can hold up to 3KB of data, 7,089 numeric, or 4,269 alphanumeric characters, so (very short) short stories should work!

        Or book chapters, spread out across the city or town, with clues at the end of where the next chapter is located, forcing readers to explore the town, as they look for the next chapters in the epic they’re reading, all while living their very own epic in the process.

        Now that’s a run-on sentence.

    So you see SCOTUS, the government can’t tell me to shut down my windows 11 printing press, because I’m reporting on its color scheme and people need to have a copy to understand my journalism.
