surveyor respondent pattern in nanomsg in python -

-

i trying write surveyor respondent pattern. throws error:

nanomsg.nanomsgapierror: operation cannot performed in state

from nanomsg import *  s1 = socket(surveyor) s1.bind('ipc://bob') s1.send(b'hello nanomsg') print(s1.recv()) s1.close()  nanomsg import *  s2 = socket(respondent) s2.connect('ipc://bob') print(s2.recv()) s2.send(b'hello') s2.close()

how can implement pattern in python?

its bug, can circumvented inserting "time.sleep(0.1)", after bind or connect statement.

from nanomsg import * import time   s1 = socket(surveyor) s1.bind('ipc://bob.ipc') time.sleep(0.1) s1.send(b'hello nanomsg') print(s1.recv()) s1.close()

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
