This was a late breaking session that was announced shortly after The Long Tail: Conversation with Chris Anderson and Joe Kraus. Unfortunately, I didn't take my tablet PC with me to the long tail session so I don't have any notes from it. Anyway, back to Google Code.
The Google Code session was hosted by Chris DiBona. The Google Code homepage is is similar to YSDN in that it tries to put all the Google APIs under a single roof. The site consists of three main parts; information on Google APIs, links to projects Open Sourced by Google that are hosted on SourceForge and highlighted projects created by third parties that use Google's APIs.
The projects Open Sourced by Google are primarily test tools and data structures used internally. They are hosted on SourceForge although there seemed to be some dislike for the features of the site both from Chris and members of the audience. Chris did feel that among the various Open Source project hosting sites existing today, SourceForge was the one most likely to be around in 10 years. He mentioned that Google was ready to devote some resources to helping the SourceForge team improve their service.
