I came across Firebase which looks good. However, I don't quite get the setup for it. Can I host Firebase on my own server and not have to subscribe to any of Firebase's plans? 回答1: Firebase offers a few products: the Firebase realtime database Firebase hosting (for hosting static resources) Firebase authentication I think you are

阅读更多关于 Comet & PHP: How to use Comet with a PHP Chat System?

问题 I have to build a simple chat system in PHP using Comet. I don't know what would be the best approach to this project.

My regards. 回答1: You may want to

Best python XMPP / Jabber client library? [closed]

阅读更多关于 Best python XMPP / Jabber client library? [closed]

问题 What are your experiences with Python Jabber / XMPP client libraries? What do you recommend? 回答1: It depends what license you can use. Some popular libraries are GPL which can cause serious issues if you need to use it for work, especially if you need to keep proprietary extensions. The LGPL libraries are a little less popular, I think, but you have more flexibility with what you can use them for. I'd once looked at using twisted directly for some simple XMPP scripting but the documentation

Comet VS Ajax polling

阅读更多关于 Comet VS Ajax polling

问题 I need to create a chat like facebook chat. With Comet I need more memory to keep the connection. With Ajax polling there is a latency problem if I send request every 3-4 seconds. So... If the latency ( 3-4 seconds ) doesn't matter, Is Ajax Polling better for my case ? 回答1: Latency is not the only problem. COMET (long-polling) "saves" your traffic - when you use polling, you cannot know, if there were changes on the server, so some of the calls may be just a waste of traffic and resources (e
