free chat website that lets you connect with people quickly and easily.
Featuring mobile chat rooms as well, helps you find and connect with single women and men throughout the globe.
Another challenge is ensuring the timely delivery of the messages themselves.
The project I'm currently working on, Facebook Chat, offered a nice set of software engineering challenges: The most resource-intensive operation performed in a chat system is not sending messages.It is rather keeping each online user aware of the online-idle-offline states of their friends, so that conversations can begin.The naive implementation of sending a notification to all friends whenever a user comes online or goes offline has a worst case cost of O(average friendlist size * peak users * churn rate) messages/second, where churn rate is the frequency with which users come online and go offline, in events/second.for free chat rooms features, amazing online chat rooms, and mobile chat at the click of a mouse.free chat now , chat no register , free text chat , random chat , Singles chat , Nickname , Age , Sex ( Male / Female ) , Country and State.This is wildly inefficient to the point of being untenable, given that the average number of friends per user is measured in the hundreds, and the number of concurrent users during peak site usage is on the order of several millions.Surfacing connected users' idleness greatly enhances the chat user experience but further compounds the problem of keeping presence information up-to-date.
