Load dynamic css in javascript -

-

i have javascript file other people use on site. creates button , loads css file hosted on our server:

 style.setattribute('href', 'http://mysite.com/assets/some.css');

the user can call in site so:

<script type="text/javascript" src="http://mysite.com/global.js"></script>

i want give user ability upload own css file on web app replace 1 setting in global.js.

currently, added custom_css:binary column in users table hold css file, requires user stay signed in on site. i'm not sure if right way approach or if there better way it. also, security risks approach?

i'm using ror backend.

any great!

update 1

i'm able store uploaded js file , load custom css, it's checking current_user - means stylesheet not rendered users. how can work around this?

i able find solution myself.

there several ways approach this:

  1. add query string js src
  2. scrape page element gets generated script

i opted option 1. when detect dynamically generated query string, send on controller in params hash , load css file accordingly.

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
