About Hacker Dictionary

What Is HackerDictionary?

HackerDictionary is the cultural dictionary of computing. We document 9,800+ terms that technologists actually use: the slang, the jargon, the idioms, the acronyms. Each entry goes beyond a simple definition to trace the term back to its origins, explain how it evolved, and place it in cultural context.

Our Mission

We trace the language of technology from the MIT hackers of the 1960s to modern AI researchers. Computing has always been driven by its own vocabulary, a living language that reflects the culture, humor, and values of the people who build software. Our mission is to preserve and explain that language for current and future generations of technologists.

What Makes Us Different

HackerDictionary is not a corporate glossary or a bare-bones dictionary. Every term we cover includes:

  • Origin stories: Where the term came from, who coined it, and why.
  • Etymology timelines: How the meaning shifted over decades of use.
  • Cultural context: The communities, debates, and movements that shaped the term.
  • Plain English explanations: Accessible summaries for non-technical readers.

By the Numbers

  • 9,800+ terms defined with full etymology and context
  • 36 deep dives exploring the history behind major concepts
  • 69 comparisons breaking down commonly confused terms
  • 33 collections grouping related terms by theme

Standing on Shoulders

HackerDictionary draws inspiration from the Jargon File tradition, started in 1975 at the Stanford and MIT AI labs and later maintained by Eric S. Raymond as The New Hacker's Dictionary. We build on that foundation while expanding coverage into the modern era of cloud computing, AI and machine learning, DevOps, cryptocurrency, startup culture, and open source communities.

Community-Driven

HackerDictionary is built by its community. Developers, security researchers, open source maintainers, and AI engineers contribute terms, suggest corrections, and help refine definitions. Every submission is reviewed by our editorial team for accuracy, tone, and completeness.
