ruby - Using rubzip2 and paperclip in rails, how to you create a temporary zip file and save it to paperclip? -

-

i had code preciously zipped load of files, created zip file in tmp file system , added files there.

i'm trying make more efficient using ruby's tempfile store file in code instead of manually writing tmp directory myself , deleting later on.

i've written code try , it…

def zip_up_files   require 'zip/zip'    t = tempfile.new(["temp-filename-#{export_type}", '.zip'], :type => 'application/zip')   zip::zipoutputstream.open(t.path) |z|     #pop files in zip...   end    #save has_attachment :download on model   self.download = file.open(t.path)   self.save    #delete tempfile...   t.close end

this sucsfullt saved tempfile .download on model. if navigate saved zip file it's not zip file garbled text document. wondering if there's missing creation or saving of zip before get's saved modle. i've tried putting type tempfile creating. looks zip's missing mimetype. i'm not sure, can help?

thanks!

the problem is, you've written binary file disk, open in text mode rather binary mode. mess data.

# opens in text mode default! #self.download = file.open(t.path)  # change to... self.download = file.open(t.path, 'rb')

incidentally, close not delete temp file. file getting deleted when file handle garbage collected. it's recommended call unlink explicitly delete temp file, otherwise you'll have tons of temp files on disk waiting garbage collected. (see synopsis , practices in tempfile docs.)

#delete tempfile... t.close t.unlink

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...
