问题 Im working on a simple chat app, probably 10 to 20 users per room. The Script that queries the database for new messages looks too simple for all the request it'll be getting. Below is the block of code that loops for new messages, the rest of the script is just getting the variables, construction of the query and the json response object: $sleepTime = 1; //Seconds $data = ""; $timeout = 0; //Query database for data while(!$data and $timeout < 10){ $data = getQuery($sql); if(!$data){ //No new

I got the following error when I get contents from file(" http://www.otherdomain.com "). file() [function.file]: php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution The domain server is linux. How to resolve this problem? Quoting: If you're having problems with fopen("url...") but you can run 'host url' in a shell window and get the correct lookup, here's why... This has had me banging my head against it all day - finally I found the answer buried in the bug reports, but figured it should really be more prominent! The problem happens when you're on an ADSL line

didReceiveRemoteNotification not being called when I tap on app icon after receiving a push notification while on background

问题 When my app is on background and I receive a remote notification, two things can happen: I tap on the push notification banner, my apps comes to foreground and didReceiveRemoteNotification is called. I tap on my app icon from the springboard, my app comes to foreground and didReceiveRemoteNotification IS NOT called. So, in the scenario 1, I can update my counter of unread messages inside the app in response to didReceiveRemoteNotification. In the scenario 2, I can't. How can I solve this

socket.io chat with private rooms

由 徘徊边缘 提交于 2019-12-04 07:35:16
问题 I started looking into node and socket.io. I already have created a simple chat application and I am amazed at how easy it was. Now, I would like to take a little bit further and provide a list of online users that have the ability to chat with each other in private. What would be the best way to approach this? I read on 0.7's new room feature. Would that be a way to go? Dynamically create a new room each time 2 users need to chat in private? But how the second user is going to be notified of

How to run a background thread in ruby?

由 南笙酒味 提交于 2019-12-04 07:29:05
I am new to ruby and thought it would be a great idea to rebuild a simple chat program I made in C#. I am using Ruby 2.0.0 MRI (Matz’s Ruby Implementation). The problem is I want to have I/O for simple server commands while the server is running. This is the server that was taken from the sample. I added the commands method that uses gets() to get input. I want this method to run as a thread in the background, but the thread is blocking the other thread. require 'socket' # Get sockets from stdlib server = TCPServer.open(2000) # Socket to listen on port 2000 def commands x = 1 while x == 1
