pubnub

问题 I have a mobile application where users can talk to each others via a chat (user to user only, not chatroom). Today, everything is synchronous. We are considering switching the solution to something more "real time", maybe using PubNub or Pusher. We are wondering about the best way to do it, given that our server will need to store every sent message. What we have in mind : Each mobile app would create a channel using user Id as the channel name. This channel would be used for mobile app /

问题 I'm looking to develop a chat application with Pubnub where I want to make sure all the chat messages that are send is been stored in the database and also want to send messages in chat. I found out that I can use the Parse with pubnub to provide storage options, But I'm not sure how to setup those two in a way where the messages and images send in the chat are been stored in the database. Anyone have done this before with pubnub and parse? Are there any other easy options available to use

问题 I've implemented a chat using Ionic2 with pubnub, the thing is how can I implement the isTyping to show it on my html ?

问题 I'm trying to get my Wink Hub working with Pubnub subscriptions in my iOS app, but all I ever get is a PNUnexpectedDisconnectCategory status in the didReceiveStatus callback. Here is the code: class AppDelegate: UIResponder, UIApplicationDelegate, PNObjectEventListener { var window: UIWindow? var client: PubNub override init() { let configuration = PNConfiguration(publishKey: "", subscribeKey: "fake-key") client = PubNub.clientWithConfiguration(configuration) super.init() client.addListener

问题 PubNub recommends "publish no faster than 5 msgs per second to any one channel." I was wondering if PubNub itself has some settings can throttle publish msgs? For example, I publish 100 msgs per second to one channel, PubNub server can drop first 95 msgs and only publish last 5 recent msgs per second. "windowing" parameter is something similar I found from PubNub, but it seems bundling msgs and compressed them instead of dropping them. "windowing" Specifies the time interval in milliseconds

问题 I am in the process of debugging some Posgtres connection leaks in our application. Few days back we suddenly crossed 100 connections when we should not be - coz we just have 8 unicorn workers and a sidekiq process (25 threads). I was looking at htop today and saw that a ton of threads were being spawned from my unicorn workers. Eg: Am I reading this correctly? This should not be happening right?

问题 Hello I am developing an auction app like tophatter.com. I want to implement an application that has background process in it. I want this process to run forever until I stop it http://eoction.com thatss our current site. The problem on our site when we refresh the page the auction also restart.
