perl - Apache server preprocessing POSTed FORM data -

-

i want display progress bar showing live status of file upload. had solution involved perl reading stdin , me ajaxing file every second or , worked fine, hosting providers seem have changed , doesn't work anymore.

what appears happening form submits data in entirety , runs script. data being uploaded first , script processes it. on big uploads page seems hang 40 seconds , "uploads" data 40 seconds, while processes data upload (during second phase progress bar works, know perl scripts running)

but... if set target of form file doesn't exist, still takes 40 seconds before comes 404, implies first thing apache accept upload?

i'm programmer more sysadmin type , advice or comments appreciated.

if had guess, sounds provider set reverse-proxy in front of perl web application. lightweight proxy handles file upload in entirety before passing request onto application in order keep resource-intensive processes waiting on network traffic.

if that's case, there's nothing can correct problem; you'll have contact hosting provider ask if there's work-around.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
