How to implement a real fast web chat with PHP? Has anybody ever wonder why Facebook chat is just so really really fast? even in IE without WebSocket. Isn't the only way is to setInterval in JS to check for new messages? But I feel it (Facebook chat box) like having instant reaction. How to implement such great thing with PHP? The instantaneous chat you're describing is generally acheived by a something called "Long Polling" or, if we're talking about AJAX, "Comet" ( Wikipedia talks about it). Polling tends to strain Apache servers, but there are some specialized servers to deal with it like

I am trying to write a simple android chat app. I have created a service class which handles all the networking communication. The DatagramSocket binding is in a separate thread. Once in while I am getting this error and the app crashes: java.net.BindException: bind failed: EADDRINUSE (Address already in use) at libcore.io.IoBridge.bind(IoBridge.java:89) at java.net.PlainDatagramSocketImpl.bind(PlainDatagramSocketImpl.java:68) at java.net.DatagramSocket.createSocket(DatagramSocket.java:133) at java.net.DatagramSocket.<init>(DatagramSocket.java:78) and this is the code which prodruces it. The

I'm doing research for making a chat based app for the iPhone (it's not really text chat in the regular sense, but the principles are the same). Maximum 6 people can be logged into the same chat room at any one time, and the most basic question is how to efficiently check for new messages? Would I need to simply poll the server periodically? Or is there a way I could trigger an event on the phone from the server whenever there is some new content to pay attention to? If having to poll all the time, I worry about the resulting lag as each participant will have to wait longer for others before

1)I want to devlop a website that has forums and chat. The chat and forums are linked in some way .Meaning for each thread the users can chat in the chat room for that thread or can post a reply to the forum. I was thinking of using django for forums and twisted for chat thing.Can i combine the two? The chat application devloped using twisted is linked to the forum. 2)If i use twisted and django what kind of web host shold i use while putting by website on web ?Shold i use a VPS? Or can i get a host that supports both? I would not combine the two per se; calls into Django would happen

Possible Duplicate: Recommended Live Chat software to add to a website? What solutions are there for creating a live support chat tool on the website? I would like to have it embedded (just like facebook chat for example, bottom of screen). A simple js i could load. Important to note: one2one chat. Preferably with a desktop client for operators. And, extra kudos for nice api's that we can later use to connect to our ruby website. I just checked out Pusher: looks great, but we have no time to implement it right now. Is there an easier "just paste & it works" kind of thing? I checked out old

We were planning to make an HTML5 based chat app using the Websockets technology. So my question is: Which are the browsers that support Websockets natively currently as of today? If a browser does not support it, what is a possible graceful fallback? Is there a polyfill that can help? Regards, Which are the browsers that support Websockets natively currently as of today? As pointed out in previous answers. See: http://caniuse.com/websockets http://html5please.com/#Websockets If a browser does not support it, what is a possible graceful fallback? If your realtime web server only supports

Could somebody explain to me the architecture behind chatroulette? I was thinking about a similar project that would only implement Audio support (for starters). Is the best way to set this up a flash server? If so, how should I go about getting into flash, will I need flex 4? I have some beginner experience with c++, c# and java but I have never developed anything for the web. I was also wondering how the randomizer matches up the participants. How would you code something like this. Im obviously pretty clueless here and I'd greatly appreciate some advice regarding this problem -- I don't

I just started learning NodeJS and Socket.io ... Until now I have this demo code, from official socket.io site: http://socket.io/demos/chat/ I am able to get the unique client's ID of each user (socket) which connects, I am still trying to figure out, How can I make my code to only connect with 1 random user at a time when somebody runs the application. I just want to make random chat like Omegle http://www.omegle.com/ Only 2 users should randomly connect and chat with each other till they re-run the app, if they come back they should get connected with someone else who is in the online queue.
