Dennis Domino

Dennis Domino is a term used within some computing contexts to describe a specific type of bug or anti-pattern. It refers to a situation where a single, often seemingly small or insignificant change in one part of a system triggers a cascade of failures or unexpected consequences in other, seemingly unrelated parts. The analogy is drawn to a line of dominoes: pushing over the first domino causes a chain reaction that topples all subsequent dominoes.

The term is often used to highlight the complexity and interconnectedness of software systems, particularly large or legacy systems. A "Dennis Domino" scenario can be difficult to debug because the initial cause of the problem is often far removed from the ultimate symptoms. This requires careful tracing and understanding of the system's architecture and dependencies.

Identifying a potential "Dennis Domino" effect often involves analyzing change logs, reviewing system architecture, and considering the potential impact of even minor modifications. Preventing such issues requires robust testing practices, thorough code reviews, and a clear understanding of the system's dependencies. Understanding the potential for cascading failures is crucial for maintaining system stability and preventing unexpected outages. The origin of the name "Dennis" in this context is not widely documented or universally agreed upon, and may be specific to certain development teams or organizations.
