iphone - Under iOS, does anyone know how UUID's are generated for executables and what information may be encoded therein? -

-

applications compiled on ios assigned identifiers (uuid's) @ compile time. these identifiers may revealed dwarfdump tool. know how uuid's generated , information may encoded within them?

almost they're generated corefoundation uuid machinery, creates them based off of mac address of ethernet card, timestamp, , other miscellaneous information. can generate own uuids running uuidgen. information encoded in them, that's there fragments of mac address. pretty relevance has may theoretically possible determine multiple uuids generated on same machine, don't know if that's possible.

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,
