Stack Overflow-esque source code

I am aware Stack Overflow isn't open source, but i have seen a MIX video of phil haack creating a Stack Overflow-like app called 'haackOverflow" . can anyone help me with the link to download its source code.

PS : I'm looking for a app that is developed开发者_如何学JAVA in ASP.NET MVC(with best practices). i have found music store, nerd dinner,and MS town hall app.

I wrote an Open Source StackOverflow-like site LampCMS. It has many features similar to SO and many featuers similar to Quora. It's written in php 5.3 and powered by MongoDB. It is very fast and can handle very high-traffic sites on a relatively inexpensive server and can easily scale horizontally to very large multi-server implementation.

Source code on gitgub.

Demo: http://support.lampcms.com

It isn't the one you mention in your question, but I believe that it is what you are after...

Don't be too put off by the style of their demo - look at the feature set and imagine your own design!
