It's great to find all those little snippets of code on the Web for your current needs, but is there anything better than getting whole application source code at once and reading it like a book? There's no better way to learn positive and negative aspects of various architecture solutions.
That's why I was trying to find some known/big websites with its source code published, but haven't found anything more than I knew already ( http://code.reddit.com/browser )
Do you know anything more?
PS. Just being curious - have you heard about any unofficial big web site source code leak?
Wikipedia's source code (MediaWiki) can be found at http://www.mediawiki.org/
The most relevant parts are
- "phase3" (the core code; this strange name is because it was rewritten a couple of times)
- extensions (Wikipedia uses several of them; which ones can be seen at Special:Version)
Additionally, here is a very detailed explanation of Wikipedia's whole architecture: Wikipedia: Site internals, configuration, code examples and management issues.
You can check out SlashCode, which is the code behind Slashdot and any other sites that use that as a CMS / blogging solution. http://www.slashcode.com
Browsing through the SourceForge repositories is just what you want. There are tons of well-known, high-quality applications, like Hibernate to give one massive example. And all the source code is right there :)
Check out Rob Conery's screencast series, MVC Storefront, where he builds a small commerce website using ASP.NET MVC.
