Programmers knowledge base web-based software? [closed]

Question

I'm looking for some software (preferrably written in php or ruby) to maintain my own knowledge base. The reason why I don't think wiki-like systems are suitable for this purpose is they don't have strict categorization (manually create categories, manually assign category to article).

Any ideas?

Thank you.

I recently started using WorkFlowy.com and using it for this purpose. Not self-hosted - but it works great for organizing your thoughts.
