youtube has, fsr, implemented an "ai generate a thumbnail for your playlist" function, and fsr, it uses an EXTREMELY low-quality text to image model really harkens back to a time when ai slop would unsettle you and give you a headache instead of just disappointing you a bit
a prompt for "fruit in the style of dramatic photography" having generated a pineapple where the honeycomb segments have been unsettlingly replaced with some kind of nuts, next to a mango with the insides of an orange, and two apple-strawberry-tomatoes. another thumbnail next to it shows an apple and a pear with their stems fused like a pair of cherries

guide to reassuring your friends
manga comic, of two crossdressing boys.
panel 1: both boys are standing in a bedroom, wearing dresses.
boy A: … come on, don't cry.
boy B: but… i'm scared.
panel 2: zoom on boy B's face.
boy B: thinking that you might start to dislike me, i…
panel 3: boy A hugs boy B, who tenses up in surprise.
panel 4: zoom on boy A's hands fondling boy B's butt.
boy A: there's no way i'd dislike you.

it honestly kinda sucks that claude broke its "style" architecture i had a response style written to talk like an overly excitable gay nerd (cause i find that charming) and like 4 months ago (left) it read like an actual person. i tried it again now (right) and it's just like… gross, dude. like wtf
omg the battle of waterloo is like SUCH a huge deal in history lemme tell u (✿◠‿◠)

so like first off it basically ended napoleons whole career?? like he'd been conquering stuff and causing chaos across europe for years and this battle in 1815 was his final defeat. after waterloo he got exiled to st helena and never came back to power again which is kinda wild when u think about how powerful he was (*≧▽≦)okay so waterloo!! 1815, june, big big deal!! [bounces excitedly] heres why everyone still yells about it~

napoleon escaped exile (like a lil chaos gremlin lmaooo) and tried to take over france AGAIN, this is called the hundred days!! and basically all of europe was like "...no" and teamed up to stop him

for those of you wondering what's different between these qr codes (this animation doesn't go up to version 40 tho, it only goes up to 8)
the "sound" ones are
* "version" i.e. its size in pixels, raw data capacity (40 versions)
* "level" i.e. its degree of error correction and fault tolerance (4 levels)
* "mask" or masking pattern (8 masks)
and the unsound thing is, the message data in a qr code is basically formatted like a series of containers of character encodings: there's ASCII (256 chars, 8 bits/char), alphanumeric (45 chars, 11 bits/2 chars), and numeric (10 chars, 10 bits/3 chars)and they go like, first a header token saying how many characters are in this segment, and then the encoded character tokens. normally the data in a qr code goes something like
```
start of qr code
segment header: encoding X; Y chars
(character token)
(character token)
…
segment header: encoding W; Z chars
(character token)
(character token)
…
data terminator token
padding
error correction data
```what i'm doing is just inserting empty containers of 0 characters, so it's like
```
start of qr code
segment header: encoding X, 0 chars
segment header: ASCII encoding, 4 chars
(character token)
(character token)
…
segment header: encoding Z, 0 chars
segment header: ASCII encoding, 5 chars
(character token)
(character token)
…
…
```
which makes it like. very combinatorial and so on. lots of ways of expressing a single message

geogebra has a symbolic calculator that allows you to switch between an exact expression and a numerical approximation, and i somehow managed to confuse it into thinking 3/2 is the square root of 2
geogebra evaluating 2^x/(1+2^x) at 0.5 and -0.5. the ratio of those constants (0.58578… and 0.41421…) is given as both 3/2 and 1.41421…

yeah it looks awful right? but it does have a tripod screw hole on the back so you won't have to hold it with the mics plugged in. zoom makes the h4essential recorder too, which does have a much better design, but it seems slightly worse in terms of tech specs *and* slightly more expensive

two of my favorite manga artists rn are kuwabara tamotsu and sal jiang. both of them draw yuri where the girls get really pissed off and beat eachother up 🥰 they're also in a doujin circle together called "monophobia", i.e. the fear of being alone. which is 😚👌
"destroy it all and love me in hell" ch 25 (kuwabara): an angry girl with a bruised face and a nosebleed grabs another by the collar and says "it's obviously because i'm in love with you!""dumb mutt girlfriend" ch 1 (kuwabara): a girl grabs another girl by her jaw and wrenches her head away. she says "don't get so close when you've got the smell of another woman on you. take a bath." the other girl grits her teeth and says "…yes.""ayaka is in love with hiroko" ch 23 (jiang): an angry woman holds another by the collar and says "when i thought you had a boyfriend, when you treated me like a kid, when you played off my confession, when you lied about yourself, when you turned me down, i still loved you after all that!""black and white" ch 1 (jiang): two office ladies fighting and falling down onto a pile of loose papers. one of them says "hah… your… innocent act… is pissing me off!"
