its an extreme example also compression doesn't "compress data" per say but rather decreses the ineficency of the unrefined version Example: in a photo alot of pixels next to other pixels will naturally be the same color so you can just say "the same as before" when compressing alot but if you were to basicly randomise all the pixel colours then that photo would reach maximum data usage , and would be imposible to further compress. its kinda like that whole trying to find infinite energy thing, every time you think you can compress more data to less you realise: the older data was inheritly inefficent or the action of compressing adds too much data to actually make the difference Edit: typo cam -> can (damn turkish outocorrect, cam=glass in turkish)

@cryomaniac-tm5mg

What I ment in the last sentence was this: ımagine you can send a photo by each pixel having 15 diffrent colours So you have 15 things you can send. Now if you use a compressing algorithm then the 15 possiblities will become 16 with the "the same as before" command. if you are using a 4bit system you can either 1: use the extra space in the 4bits (2^4=16, 16-15=1) to carry extra data for an extra pixel (in this case. if you are efficent you can use 15×4bits to transmit 16 pixels or you can reserve one of those for the same as before thing. you cant do both since specifying which one you are doing for each pixel will cost valuable data, and if you do the math you will realise on avarage the refined version (assuming randomised data) will be of either the same or less efficency than the raw data one

File sizes can be weird, due to the fact that binary doesn't go in 1000s like normal metric, but in 1024s. Maybe it's actually like 68,000 bytes and change, and is just rounded up as 69 KB for ease of reading. Honestly, I'm more interested as to why they can't just slap PNGs directly onto the signs instead of decompressing them.

@OpenKeith

​​@@ultravioletcombat5933 The image has to be decompressed in order for the GPU to use it as a texture. The GPU has to be able to "jump around" the image and read whatever pixels it wants in any arbitrary order, which would be far too complicated to do by seeking back and forth in a compressed data stream (you can't just jump a fixed number of bytes to get to the desired pixel), so it needs you to decompress the image beforehand and hand it the raw array of pixel values.

I like that for a time you could enter a server with a functional memetic hazard all ready to go. Go full Perseus.

thank you for the great video!

Fun fact: until the release of Windows 10 21H2, all versions of Windows 8, 8.1 and 10 were susceptible to the exact same bug when copy-pasting an extremely horizontally large png from one place to another. It tries to unroll the png into a bitmap in memory to allow the destination to convert it into another format if it wants to, but if the image unrolls too large, it writes the clipboard buffer out-of-bounds. We even determined that you could interfere with other process memory that way, so it was given a CVE and patched in a week. Windows 8, 8.1 and 10 are no longer vulnerable to it. I discovered this after making a meme by stitching together large images of regional indicators (the white letters on a blue background) approximately 250k pixels wide and pasting it into Discord. Instant bluescreen, every time. We called the exploit "bluebomb", because blue was the dominant color in the program. There's a 10 line C file to reproduce the error, instantly crashing any vulnerable Windows system upon executon. Good times.
