i have developed udp client server application. want check if client sends string "exit", server receives string, compares "exit" string , program exits. in case, server not able compare received string "exit" string. below coding: client: char exitbuffer[]="exit"; if (sendto(socketidentifier,exitbuffer,strlen(exitbuffer) , 0 , (struct sockaddr *) &connectedsocket, sizeof(connectedsocket)) == socket_error) { exit(exit_failure); } server: if ((recv_len = recvfrom(socketidentifier, receivebuffer, sizeof(receivebuffer), 0, (struct sockaddr *) &clientsocket, &clientsocketlength)) == socket_error) { messagebox(null, exit(exit_failure); } // comparing contents of receive buffer if (receivebuffer == "exit") { exit(0); } i tried memcmp , did :) comparison done on server side follows: if(memcmp(receivebuffer,"exit",5) == 0) { //receivebuffer eqaul "exit". }

i have class has attribute pandas dataframe. define attribute in same class changes when dataframe altered. thought setter might correct approach haven't been able work. here toy example: import pandas pd class foo(object): def __init__(self, df=none): self._df = df self.altered = false # bool, set true if self._df changes @property def df(self): return self._df @df.setter def df(self, df): self.altered = true # since _df might change here set self.altered true self._df = df df_test = pd.dataframe([[1,2,3]], columns=['a','b','c']) cl = foo(df_test) cl.df.loc[0, 'a'] = 3 # change default value in dataframe print(cl.df) print(cl.altered) which prints altered dataframe cl.altered still set false. any suggestions? i don't know pandas. setter isn't called because line was: cl.df.loc[0, 'a'] = 3 it have been called if line was: cl.df = 3 one thing stor...

is there way make tensorflow variable larger? like, let's wanted add neuron layer of neural network in middle of training. how go doing that? answer in this question told me how change shape of variable, expand fit row of weights, don't know how initialize new weights. i figure way of going might involve combining variables, in initializing weights first in second variable , adding in new row or column of first variable, can't find lets me either. there various ways accomplish this. 1) second answer in post ( https://stackoverflow.com/a/33662680/5548115 ) explains how can change shape of variable calling 'assign' validate_shape=false. example, like # assume var [m, n] # add new 'data' of shape [1, n] new values new_neuron = tf.constant(...) # if concatenating add row, concat on first dimension. # if new_neuron [m, 1], concat on second dimension. new_variable_data = tf.concat(0, [var, new_neuron]) # [m+1, n] resize_var = tf.assig...

i hear these terms , wonder difference? how related continuous builds , continuous deployments? continuous integration / continuous builds getting developers commit code source code repository little , (and latest version repository, further changes based on other developers recent changes). reduces time wasted on merge resolution, it's easier merge in case. the process best automated using build server, can run unit tests. feedback provided developers in case of build / test failure, issues can fixed quickly. continuous deployment involves automated deployment of build artefacts build process onto test , production environments. mitigate risk involved this, people use feature toggles separate release (in controlled way) deployment. continuous delivery less technology , more organisations approach software delivery (although make heavy use of automation). devops larger area emphasises breaking down barriers between developers , operations teams, , getting...

what i'm trying achieve view controller can display items in both list form , collection form button can switch on between 2 display options. so i've implemented uiviewcontroller can hold both uitableview , uicollectionview . when view controller loads @ first time, uitableview appears fine. when press switching button (it changes self.view uicollectionview ), ends black view. and when try uitableview pressing switching button (again, changes self.view previous uitableview ), nothing happens. stays black. is there should after changing root view of view controller? it not recommended behavior change view of uiviewcontroller past point in time @ loadview called. you'll want view controller have one, persistent view lifetime. i'd recommend 1 of following. layering table view / collection view on top of view controller's view. way you're not monkeying main underlying view itself. having 2 instances of view controller, 1 table , oth...
