20151115 - glitch

A glitch is a short-lived fault in a system. It is often used to describe a transient fault that corrects itself, and is therefore difficult to troubleshoot. The term is particularly common in the computing and electronics industries, and in circuit bending, as well as among players of video games, although it is applied to all types of systems including human organizations and nature.

Computer glitch

A computer glitch is the failure of a system, usually containing a computing device, to complete its functions or to perform them properly.
In public declarations, glitch is used to suggest a minor fault which will soon be rectified and is therefore used as a euphemism for a bug, which is a factual statement that a programming fault is to blame for a system failure.
