python - No POST responses from real time callbacks -

-

basic idea of i'm doing. want grab users' likes , print them in cli application (python script listens get/post messages using twisted framework).

i have done oauth via inline canvas html:
<a target='_top' href="https://www.facebook.com/dialog/oauth/?client_id=1111111111111&redirect_uri=https://apps.facebook.com/xxxxxxx/&scope=user_likes">grant permissions</a>

right seems well?

okay i've gone real time subscriptions section within facebook app section , added

see image* :http://i.stack.imgur.com/l2i3t.png , when run test, python code returns result, see*: http://i.stack.imgur.com/9d2ek.png

so i'm stuck though. because expect happen when like callback show in callback script. i'm printing given render_post , render_get , responses come out fine, example

get {'hub.verify_token': ['test'], 'hub.challenge': ['73678294'], 'hub.mode': ['subscribe']} {'hub.verify_token': ['test'], 'hub.challenge': ['2038003566'], 'hub.mode': ['subscribe']}

but when go off , something, either myself or test user (with oauth completed) there's no post value. nothing @ all!

i figure there's i'm missing here. i'm expecting see 

{   "data": [     {       "category": "author",        "name": "iain m. banks",        "id": "111960934488822",        "created_time": "2013-04-22t13:21:42+0000"     },      {       "category": "movie",        "name": "the life of brian",        "id": "110881634936650",        "created_time": "2012-12-17t07:48:24+0000"     }   ],    "paging": {     "next": "https://graph.facebook.com/111111111/likes?limit=2&offset=2&__after_id=110881698346650"   } }

in post can proceed rest of code. hope can clear me! thank in advance!

*you need @ least 10 reputation post images

the field likes corresponds user/likes

all pages user has liked.

the user object supports following connections

this object supports real-time updates following connections: feed, friends, activities, interests, music, books, movies, television, likes, checkins.

https://developers.facebook.com/docs/reference/api/user/

so liking something may not want. ensure object liked page. facebook post callback.

in addition ensure seeing post variables, occur in request.args , not request

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
