CodeCodex

Today at DZone.com I ran across the CodeCodex which could subsume the Software Provenance Database. The latter is (will be?) a place to store code snippets that help your program figure out "where am I?". The idea of CodeCodex is simply to be a repository of any small bit of useful code, from sorting implementations to CSV import code, in any language.

Google still does a reasonable job at finding existing code of course, and for things like these they're usually in the format of articles with some good explanatory text. CodeCodex uses a Wiki so the code can also be presented as an article, and can include implementations in multiple languages. Anyone can contribute, refine, and discuss once they land on the page.

This thing has been submitted to Digg (twice) and reddit within the past year, but I hadn't heard anything about it before.
