Glossary
This is a glossary of terms as used in this essay. These do not necessarily have a standardized meaning to other people. Eric S. Raymond has compiled a massive and informative glossary[HackerDict] that rather surprisingly can pleasurably be read cover-to-cover once you can appreciate a fraction of it.
