Software engineering has never been an easy profession. Knowledge is assumed. Misunderstandings flourish. An opaque profession does not do itself any favors. This handbook is a modest attempt by the author to lay out an open source glossary of terms, for the benefit of practitioners everywhere. The Glossary Use the glossary on the left to look up terms and concepts. Each term in the glossary has a short definition, a section for related tags, and links to other resources on the internet, if any.
