javascript - Nodejs - Simple Echo Server not working -


I do not understand why I can not write in the socket. I do not know whether my event is made properly or not, I am trying to learn Nodes and I'm new to JavaScript. 

  var events = need ('events'); Var Net = Requirement ('Net'); Var channel = new events Enter Emiter (); Channel.on ('included', function (socket) {this.on ('broadcast', function (data) {socket.write (data);})}}); Var server = net.createServer (function (socket) {socket.on ('connect', function) {channel.emit ('join', socket);}); Socket.on ('data', function (data) {data = data.toString (); channel.emit ('broadcast', data);});}); Server.listen (8888);    
 
 
 The event  connect  for a socket is only emitted My understanding, when you connect as a client; You're doing a server here, however, when callback is inside the  net.createServer , you're already connected to the socket, even if the  connect  event is emitted Even if you have gone, you will subscribe with it  socket.one ('connect', ... ... is too late.)  
 In return, because  connect < / Code> Callback is not called, you are never emitted on  joining  event and  on the event channel The broadcast handle  event handler is never registered, and the  socket. Writing  statement is never called. As mentioned, some  console.log  statement will help you to figure out which code is actually executed and reducing this issue.  
 You can just fix it by removing the  socket (but 'connect', ...) and the external function is doing it correctly, i.e.,  
  var server = net.createServer (function (socket) {console .log ("connect!"); Channel.emit ('join', socket); socket.on ('data', function Data) {...

c - Mpirun hangs when mpi send and recieve is put in a loop -

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
