dogfoodn. [Microsoft, Netscape] Interim software used internally for testing. "To eat one's own dogfood" (from which the slang noun derives) means to use the software one is developing, as part of one's everyday development environment (the phrase is used outside Microsoft and Netscape). The practice is normal in the Linux community and elsewhere, but the term `dogfood' is seldom used as open-source betas tend to be quite tasty and nourishing. The idea is that developers who are using their own software will quickly learn what's missing or broken. Dogfood is typically not even of beta quality.
