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.
Race and ethnicity in Latin America
An important phenomenon described for some parts of Latin America such as Brazil and Mexico is "Whitening" or "Mestizaje" describing the policy of planned racial mixing with the purpose of minimizing the non-white part of the population. This practice was possible as in these countries one is classified as white even with very few white phenotypical traits and it has meant that the percentages of people identifying as fully black or indigenous has increased over the course of the twentieth century as the mixed class expanded. It has also meant that the racial categories have been fluid. Unlike the United States where ancestry is used to define race, Latin American scholars came to agree by the 1970s that race in Latin America could not be understood as the “genetic composition of individuals” but instead “based upon a combination of cultural, social, and somatic considerations. In Latin America, a person's ancestry is quite irrelevant to racial classification. For example, full-blooded siblings can often be classified by different races (Harris 1964).
