json - Weird HTTP data accumulation on App Engine with Python and CouchDB -

-

i'm trying make relatively simple app engine app fetch pages on daily basis , post data couchdb server. i've got following code in app engine app (with couchdb-python library):

    # post result couchdb     price_data = {       'source': 'blah',       'date': str(result.headers['date'])     }     db.save(price_data)     db.put_attachment(price_data, file_one, 'prices_one.txt')     db.put_attachment(price_data, file_two, 'prices_two.txt')

file_one , file_two results earlier urlfetch requests.

now works fine except first attachment gets posted price_data json ({ 'source': 'blah', 'date': 'date here'}) @ beginning of prices_one text file, , second attachment gets prefixed both price_data json whole prices_one text file, followed actual prices_two.txt file.
i'm sure if tried add third attachment, post accumulated data one.
if go on couchdb @ file in db, it's full file, { 'source': 'blah', 'date': 'date here'} @ beginning.

any ideas causing app engine keep resending previous data each new http post? also, should note doing same thing before started using couchdb-python library, seems app engine related don't understand.

during investigation, try use raw http library instead of couchdb library. suggest native app engine library (urlfetch or perhaps urllib2). couchdb api simple, not have difficulty.

is there difference in result?

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
