Realtime Web with PocketIO
The Internet is changing direction. More and more web-sites want to notify their visitors in real time about changes that happen on the server (for instance, a different visitor uploaded a photo).
A library called Socket IO unifies all the various ways to send messages from the server to the computers of the visitors and allows the programmer to write an Internet application that gets updated in real time. vti implemented the library in Perl as Pocket::IO.
In this talk, I will present the ideas behind Real Time Web, including code excerpts in Perl which use the library in order to create interactive sites.
