Google Cloud Messaging for Chrome channelId unique per device? -

-

suppose have extension installed on 2 computers, , logged both same google account.

will chrome.pushmessaging.getchannelid return same value both computers? there way request each individual install gets own channel? cannot find information readily available anywhere.

the question asked here on stack overflow https://stackoverflow.com/questions/13235810/google-cloud-messaging-and-identity, there no answer given.

from observe, channel id unique user's account, not unique install. not sure if intended behavior or can count on being case.

i think channel id per application id , stay way. otherwise, think how complex send message to, say, 100,000 installations of app. you'd have keep file of 100,000 channel ids, , take long time invoke api 100,000 times, since channel id part of api call send message.

sorry... wrong. quote https://developer.chrome.com/apps/cloudmessaging:

"the push messaging service returns channel id client; id linked app id , user."

if server needs send messages installations of app, needs keep track of channel ids sent server applications, , send message channel ids.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
