azure - Programmatically spawn new instances of a worker role -

-

is possible programmatically spawn new instances of worker role? have worker role that's dependent on service bus queue(s) grabs messages , puts data table storage, sql database , sends out notifications. need able add more instances depending on sb queue sizes can gradually receive larger amounts of messages in future. possible me control code? , in case how?

there multiple ways achieve functionality:

1) windows azure supports auto-scaling based on amount of messages in service bus queues. can configure scaling work inside azure management portal. free while in beta, , price has not yet been announced when live.

2) there open-source api called wasabi microsoft's patterns , practices group. you'll need place host it, it'll communicate azure service management api on behalf , provide framework implementing own auto-scaling based on service bus queues. using it, instrumenting configuration xml files

3) if don't mind using 3rd party products & services, there service called azurewatch (which i'm affiliated with) give way scaling based on service bus queues azure portal, it'll have bunch of other choices, features , services.

4) can use service management api directly change instance counts, don't recommend using directly api's such wasabi being around.

i wrote blog on auto-scaling choices http://blog.paraleap.com/post/2013/07/29/windows-azure-auto-scaling-options-side-by-side-comparison

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
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...
