V3147. Non-atomic modification of volatile variable. V3148. Casting potential 'null' value to a value type can lead to NullReferenceException. V3149. Dereferencing the result of 'as' operator can lead to NullReferenceException. V3150. Loop break conditions do not depend on the number of iter...
Cheslav Versky got his start in systems engineering by hacking an early programmable calculator with one hundred steps of volatile memory, and 15 save registers. He later earned a degree in pure math, served a stint at a pioneering genomics startup, and spent over 20 years designing and impl...
