  • So I think it’s still probably unclear to people why “mix of keywords and identifiers” is bad: it means any new keyword could break backwards compatibility because someone could have already named a type the same thing as that new keyword.

    This syntax puts type identifiers in the very prominent position of “generic fresh statement after semicolon or newline”

    …though I’ve spent like 10 minutes thinking about this and now it’s again not making sense to me. Isn’t the very common plain “already_existing_variable = 5” also causing the same problem? We’d have to go back to cobol style “SET foo = 5” for everything to actually make it not an issue




  • I actually kind of looked at (jpeg) compression artifacts, and it’s indeed true to the extent that if you compress the image bad enough, it eventually makes it impossible to determine if the color was originally flat or not.

    (eg. gif and dithering is a different matter, but it’s very rare these days and you can distinguish it from the “AI noise” by noticing that dithering forms “regular” patterns while “AI noise” is random)

    Though from a few tests I did, compression only adds noise to comic style images near “complex geometry”, while removing noise in flat areas. This tracks with my rudimentary understanding of the discrete cosine tranform jpeg uses*, so any comic with a significantly large flat area is detectable as AI based on this method, assuming the compression quality setting is not unreasonably low

    *(which should basically be a variant of the fourier transform)

    I recreated most of the comic image by hand (using basic line and circle drawing tools, ha) and applied heavy compression. The flat areas remain perfectly flat (as you’d expect as a flat color is easier to compress)

    But the AI image reveals a gradient that is invisible to the human eye (incidentally, the original comic does appear heavily jpeg’d, to the point I suspect it could actually be chatgpt adding artificial “fake compression artifacts” by mistake)

    there’s also weird “painting” behind the texts which serves no purpose (and why would a human paint almost indistinguishable white on white for no reason?)

    the new ai generated comic has less compression, so the noise is much more obvious. There’s still a lot of compression artifacts, but I think those artifacts are there because of the noise, as noise is almost by definition impossible to compress


  • The thing missing here is that usually when you do texture, you want to make it visible. The AI ‘watercolor’ is usually extremely subtle, only affecting the 1-2 least significant bits of the color, to the point even with a massive contrast increase it’s hard to notice, and usually it varies pixel by pixel like I guess “white noise” instead of on a larger scale like you’d expect from watercolor

    (it also affects the black lines, which starts being really odd)

    I guess it isn’t really a 100% proof, but it’s at least 99% as I can’t find a presumed-human made comic that has it, yet every single “looks like AI” comic seems to have it


  • I also noticed how it suddenly went from great to crap.

    But the real reason I think is ironically AI. It used to be that you could easily crawl the web, but after the AI craze, images suddenly became valuable to crawl and every website gets bombarded by scrapers, and are adding more and more countermeasures to make it more difficult, so tineye’s own image scraper probably can’t compete with them and so can’t find any new images


  • I agree that the “arm things” are wrong, as it’s pretty clearly just an ‘artistic choice’ that a human could very much do.

    But that said these images are 100% provable to be AI. If you haven’t built up the intuition that immediately tells you it’s AI (it’s fair, most people don’t have unlimited time for looking at AI images), these still have the trademark “subtle texture in flat colors” that basically never shows up in human-made digital art. The blacks aren’t actually perfectly black, but have random noise, and the background color isn’t perfectly uniform, but has random noise.

    This is not visible to the human eye but it can be detected with tools, and it’s an artifact caused by how (I believe diffusion) models work




  • the trick is of course to look for the most disliked comments. Here’s a couple

    All humans are basically pure evil.

    You are probably cruel and violent to vulnerable individuals more than three times a day.

    Older men having sex with sexually mature teen girls is fine

    DUI laws are too strict. It shouldn’t be all or nothing at .08 BAC but more severe punishments for more severe inebriation. .08 is pretty low and people who drink regularly can function fine at that level.










  • get a motorized height adjustable standing desk, an egg timer and a slow treadmill, set the timer to 16 minutes and 43 seconds, every time the timer runs out, rotate between standing position, sitting position and walking position while resetting the timer.

    When you’re ready to level up, upgrade from just an office chair for the sitting positon to a mixture of office chair, saddle chair, prayer mat and stout 19th century four-legged wooden stool certified handmade in the russian far east. Rotation as follows:

    standing -> office chair -> treadmill -> saddle chair -> standing -> prayer mat -> treadmill -> flat stool -> repeat.

    When you’re ready for the endgame, upgrade from an egg timer to a stochastic bell timer powered by a brass cyclograph. This eliminates any possible linear relationship with your BRAC cycle, ensuring a well-rounded dynamic stress regimen.
