A computer with hair, dust, or other forms of trash covering the vents releases particulates into the air, which, in turn, could aid in the triggering of allergies or even asthma or respiratory issues, especially within the warm climate of Brisbane, where air conditioning is a frequent necessi...
User spins locks may consume OS thread scheduling resources unnecessarily since the OS scheduler may be unable to determine if it should yield to another program thread rather than spin. It is generally recommended to issue sleep/wait instructions rather than spin locks. ...
