if you tell a lie only once in a while, you can call those supine lies, since you are not prone to lying

I wonder what the probability that 32 random bytes happens to be valid UTF-8 is

fun fact: after the two bytes of QR code data wrapping (0x420…0) and ten bytes of error correction, there are still 7 empty modules (above the bottom finder pattern) that are filled with the mask pattern since they have no data

the details in brief:

• it computes a Version 2 QR code (25x25 modules), with Low error correction (Version 1 cannot fit 32 bytes, and larger versions would mean more code required to generate it)

• It does compute the 10 bytes of error correction properly! that’s the Galois field stuff, and it isn’t too bad with these hardcoded parameters

• it uses a fixed mask pattern 0, since evaluating all mask patterns would be way too much code

• it generates the QR code in a single loop, walking the complicated zigzag pattern so that it pulls out the encoded data in the right order once it knows that none of the static patterns apply

maybe some alternative choices could be made (generating the QR code in another orientation?), and there’s probably a few more tweaks left to reduce it even further, but subjectively it feels pretty close to optimal

wait, we can literally just use JavaScript template literals for Verbal Expressions, has someone done this before?

i guess it is still good to be specific, because .xcf is an image but not one that browsers will display, for example

… turns out i don't really need to be looking at chromium source

wanna know if it's an image? check if the mimetype starts with image/, and so on for audio/, video/, and font/
