Why does 4chan give files new names when you download them?

>>105695811 (OP)
files are named after the unix timestamp upon upload.
this is literally done because in 2004 or whatever when moot was retarded he decided this was a excellent way to prevent possible filename exploits (it was)

Why aren't there more duplicates if the file name matches the upload time. There's gotta be a bunch of times 2 anons upload ath the exact same time.

Sturdych@n lets you download files with their original names

>>105695972
that's my impression too
is it just the higher testosterone?

>>105696413
yes thats why there is a glitch where you post a picture and it posts something else.
doesnt happen often, usually the person brings it up
>wtf thats not waht i wanted to post

>>105696603
also the unix timestamp (default is just seconds) they use has the milliseconds, so it'd be even rarer for people to upload at the exact same millisecond or nanosecond i forgot.

iirc it used to be an issue when the timestamps had a lower resolution. But now, I think they also have some resolution heuristic in place that will resolve conflicts without collision.
Somebody can probably consult with the leaked source to confirm.

Tried to find an AI that would turn her white but none of the cucked online services allowed it

how long did she spend straightening her hair that day

Her black cuck does it for her as prep for his White bull

Why not MD5 hashes?

Why not screenshot or screen record?

Takes more compute?

>>105696843
it's AI.

I think so. Black girls seem to be the only ones who really love cum and getting "nasty" (and not in a purely performative way like white whores on porn sites)

That's because niggers are so fucking ugly to the point that your deformed asses look passable to them.

>Takes more compute?
Hashes are computed upon upload, so no, it wouldn't.

>>105700937
>>105702742
It would only take more compute on *delete* since you have to check in SQL if a file of a given has exists elsewhere on the site or not.

The up side is that it would significantly reduce the active content size, and if you use a htaccess trick then it can also allow arbitrary file names to be used.
For ex. store the file as files/{hash}/raw.jpg, and have a htaccess rule that any access to files/{hash}/{filename}.jpg will serve raw.jpg.
This may put more pressure on the http server and even allow retards to abuse it by using nigger file names.

>>105696413
this does happen, but on the upload not the download. every once in a while you will upload something and it will become a completely different image. happened to me twice so far

>>105696413

Yes, this used to happen all the time, you'd end up with the file you uploaded being changed to something else that someone uploaded at the same time.
Devs changed the file name to use thousandths of a second to reduce the chances of this happening, but it can still happen.

>>105696413
pure luck. it has happened sometimes on 4chan.

>>105696603
Honestly that glitch is so funny it deserves to stay.
