If you have a .edu email, digitalocean used to give out a $100 voucher. I think the lowest tier of hosting is about $5 a month so you can get a little under 2 years worth of hosting out of it.

vultr�s lowest tier is $3.50 a month for a similar type of vps, they also have some kind of sign up bonus. if you really want to cheap out like me

honestly im pretty sure that's because atm im not caching the images so it's doing the math again every single time (the responses are cached to keep the script from sending like 6 billion get requests)

tonight im gonna work on caching the images tho

sounds like its time for redis

a forums authentication provider

say I want to prove I own the forums account eschaton

I create an account in your app, tell it my forums username is eschaton, and it gives me some derived hash to put on my profile

I put the hash on my profile and tell your app �ok, verify me,� now it knows the app account and the forums account are related�and I didn�t actually have to give you or anyone else any �real� info about myself

and your app can act as an OAuth provider that confirms my forums identity

so if someone makes some other app for forums peeps, they can just use an OAuth flow for a �forums login identifier� such as https://forums-auth.hbag.com/eschaton (or whatever your app server and domain is)

now that other person�s app can trust it�s being used by forums poster eschaton and not someone pretending to be me

yo hbag if you actually did this it would be pretty impressive to future employers i bet

well anyway now im trying to figure out if there's a way to test if an image is entirely transparent
as in, test if the image is nothing BUT transparent pixels, no color whatsoever

if you dig in to the png spec youll find this shouldnt really be that hard. start here: https://www.w3.org/TR/PNG/#11transinfo

hbag posted:

welp after reading this im not sure if theres an alpha channel for the ENTIRE image's transparency or if there's only alpha channels for individual pixels

realistically your image library probably can do this for you. without having used it before i'd probably try this method and see if the max value for the alpha band is 0, assuming there is an alpha band

https://pillow.readthedocs.io/en/stable/reference/Image.html#PIL.Image.Image.getextrema

idk if that will actually work but read the docs imo

i dont think checking the transparency of a pixel at most 32,400 times is very efficient
ill give it a try

32,400 is not a big number for a computer though

You can just iterate through the pixels and check the alpha value, but unless people are using giant transparent avatars maybe you should just check whether the avatar is like 5x5 or smaller?

yeah and because this problem is embarrassingly parallel you can parallelize it for efficiency, each �process� only needs to check one pixel each and your result is still accurate

code:

from multiprocessing import Pool

def is_transparent(alpha):
  return alpha == 0

# imagine this is a sequence of every pixel's alpha value
alphas = range(32400)

if __name__ == '__main__':
  with Pool(processes=32400) as p:
    x = p.map(is_transparent, alphas)

  print(all(x))

Fart simpson is just trying to make everything complicated.

i already posted a link to the pillow docs for the built in method that tells you the min and max pixel values for an entire band of the whole image :shrug:

seems pretty simple and useful here to me

okay so the code assumes you have a 1-dimensional list that has all the pixel values of your av image.
it defines a function that tells you if the image is transparent or not, and then starts a (lightweight thread, i think is the default?) pool of executors that each take a single entry in that list and calculate if that pixel is opaque or transparent, and then the all() (iirc) tells you if any of them are opaque

the use of the map function there is some unintuitive stuff to newcomers � you�re not calling the is_transparent function in that map line. you�re passing the function itself in as an object that then gets called by map() with the proper alpha array entry for each one in the list.

i can never remember what the technical cs term for it is but it�s one of those things that broke my mind when i learned ruby from a codebase full of people who loved map and filter and the like.
rip vine

actually from what i can tell in the docs, it forks 32,400 new python interpreter processes and sends the alpha value of one pixel and the is_transparent function to each process. each process calls is_transparent on the value of the one pixel it was assigned, and passes the result back to the main process. the main process collects all the results and puts them into a sequence called x, and all() tells you if all of them are transparent, or at least one isn�t transparent

so basically what you said but it�s forking a new process for each pixel to maximize parallelization

As noted earlier a single threaded version checks the whole avatar in 7 milliseconds so you could have people doing this 12 million times a day on average before you even start to overlap requests, let alone produce noticeable lag.

that 7 milliseconds also included constructing the list of values and printing to console too!
