Facebook's Cross-Language Network Library
koreth writes "Facebook has released Thrift, a toolkit for making remote method calls. It generates interoperable network code in C++, Java, PHP, Python, and Ruby. Its protocol is much more lightweight (and probably much higher-performance) than SOAP or CORBA. Facebook uses it internally for high-traffic services like search. The license is extremely permissive."
You do realize that Facebook is a fantastic example of a clean, functional UI that only uses fancy 'web 2.0' features ala AJAX where it's actually useful?
MySpace, on the other hand, is a piece of shit.
