Race condition
A race condition or race hazard is the behavior of an electronics, software, or other system where the system's substantive behavior is dependent on the sequence or timing of other uncontrollable events. It becomes a bug when one or more of the possible behaviors is undesirable.
Judicial aspects of race in the United States
Americans feared that mixed race citizens would be able to reap the benefits of being white and instituted laws to prevent this. Mixed race citizens could legally categorize themselves as white because of their ability to self-report race to the census bureau, the requirement of choosing only one racial category, and the ability of those who were only marginally black to appear white. By 1890 people were required to report any degree of African or Native American ancestry. The idea that a single drop of African or Indian blood qualified someone as officially black or Native American was a generally obeyed legal principle, although the “one-drop” rule was never codified federally. This qualification meant the mixed race individual in question could never obtain the benefits of being white.
