het posted:I can't even tell if you're joking, maybe I'm dumb using a gig of memory on a modern computer is not a problem like right now, on my computer: skype is using 400 megs of memory of who knows what. I havent even used it, it's just sitting in the background. loving putty uses over 100 megs for showing a bunch of text in a terminal. those are my top two non-browser memory using programs right now. oh no, my megarams

i guess your point is having lovely resource management is bad? if so, i agree, but you can get away with some amazing actual poo poo depending on the environment.

tef posted:tbh this is a perfectly good strategy for short running programs, assuming you'll finish working before you run out of memory. the flash vm has this thing where garbage collection will only go so far down the tree. once it hits a certain depth it gives up and says "welp, too far down, im not goin all the way down there, better just leave it where it is." Which sounds insane until you realize that the average lifespan of a flash object is 30 seconds. they optimized for the common case and, welp, there u go.

use as much memory as you want. theres no reason to aggressively manage it yourself. as long as you arent constantly destroying and creating large objects you'll be fine.

seriously the worst thing about cs nerds and useless academics is how not only are they incapable of just doing what works, but they actually see it as a moral good. you're a bad programmer unless you do all this extra unnecessary poo poo computers have been able to do for you since the eighties!

the people you're thinking of who make tradeoffs based on analysis of the problem instead of spraying projectile diarrhea into a text file and begging a vm to run it are "engineers"

you know what i like to do in java? i read an image file into an array of 32-bit packed pixels, aarrggbb. i then make a copy of those pixels, separating each channel in each pixel into their own double. then i do my processing using those doubles. i'll probably make several copies of those doubles during the various processing steps. once i'm done, i'll pack them into yet another int array. i never free one byte of memory. processing one 5-megapixel image will use several hundred megabytes of memory.

what does using doubles buy you in that case btw? is it just that narrow integer arithmetic makes things lovely when you're doing your fft arithmetic?

probably nothing. it might have affected the color or a pixel or two in the whole image compared to integer math, but ehh. if you want to gamma correct your images before/after other processing steps, you might want to separate your channels into floats. doubles are probably overkill in any case.
