database - Password in postgres 8.3 not working -

-

i have installed postgres 8.3, entered test password while installation...my problem each time try access local database...each time enter password...it database connecting failed...i have tried change password via command line not work...even tried change configuration file...it not work...is there way out me make database work? reply...

often people cannot connect postgres password because configured default use ident authentication local connections. try switching postgres system account , connecting username. if in without password you're configured ident. can check authentication methods in pg_hba.conf.

if want switch using passwords local connections, can modify setting in pg_hba.conf. @ bottom of file there's section this:

# not disable! # if change first entry need make sure # database # super user can access database using other method. # noninteractive # access databases required during automatic maintenance # (autovacuum, daily cronjob, replication, , similar tasks). # # database administrative login unix sockets local           postgres                          ident sameuser  # type  database    user        cidr-address          method  # "local" unix domain socket connections local                                         md5 #ident sameuser # ipv4 local connections: host                    127.0.0.1/32          md5 # ipv6 local connections: host                    ::1/128               md5

you can see on second "local" line have changed setting use md5 authentication instead of ident sameuser. allows me log in database user system account using correct password. if make same change , restart postgres might solve problem.

be careful not change first "local" line. postgres user super user , if change authentication mechanism may not able in.

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....
