Race condition
Race conditions arise in software when an application depends on the sequence or timing of processes or threads for it to operate properly. As with electronics, there are critical race conditions that result in invalid execution and bugs. Critical race conditions often happen when the processes or threads depend on some shared state. Operations upon shared states are critical sections that must be mutually exclusive. Failure to obey this rule opens up the possibility of corrupting the shared state.
Racialism
In 1903, W. E. B. Du Bois said that racialism is the philosophical position that races existed, and that collective differences existed among such categories, the races. He further stated that racism required advancing the argument that one race is superior to other races of human beings. In "In My Father’s House" (1992), Kwame Anthony Appiah summarized Du Bois's philosophical stance that "racialism" is value-neutral term and that "racism" is a value-charged term.
